Abra o terminal e digite os seguintes comandos:&lt;br /&gt;
&lt;br /&gt;
&lt;ol class=&quot;syntax highlighted&quot;&gt;
&lt;li class=&quot;line ln1 alt first&quot;&gt;&lt;div class=&quot;source bash&quot;&gt;
&lt;span class=&quot;bash&quot;&gt;sudo add-apt-repository &lt;span class=&quot;string&quot;&gt;&quot;deb http://archive.canonical.com/ $(lsb_release -sc) partner&quot;&lt;/span&gt;
&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li class=&quot;line ln2&quot;&gt;&lt;div class=&quot;source bash&quot;&gt;
&lt;span class=&quot;bash&quot;&gt;sudo apt-get update
&lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;li class=&quot;line ln3 alt&quot;&gt;&lt;div class=&quot;source bash&quot;&gt;
&lt;span class=&quot;bash&quot;&gt;sudo apt-get install skype&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;source bash&quot;&gt;
&lt;span class=&quot;bash&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;source bash&quot;&gt;
&lt;span class=&quot;bash&quot;&gt;Pronto, bom bate papo! &lt;/span&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;/ol&gt;

A dica de hoje vai para usuários iniciantes do Kali Linux. Durante a instalação, o Kali Linux solicita aos usuários que configurem uma senha padrão para o usuário &lt;em&gt;root&lt;/em&gt;.
 Entretanto, caso você opte por iniciar a imagem live ao invés de 
instalar, as imagens i386, amd64, VMWare e ARM são configuradas com uma &lt;strong&gt;senha de root padrão – “&lt;span style=&quot;color: red;&quot;&gt;toor&lt;/span&gt;“&lt;/strong&gt;, sem as aspas.&lt;/div&gt;

Python é uma linguagem super poderosa, prática e bastante fácil de se aprender.&lt;br /&gt;
Muitas vezes quando estamos escrevendo um programa em Python nos perguntamos se estamos programando ou escrevendo um poema. De tão simples e prático as vezes parece um texto em inglês, pois parece muito com a linguagem humana.&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Um pouco de história&lt;/b&gt;&lt;br /&gt;
A linguagem de programação Python foi criada em 1991 por Guido van Rossum no centro de matemática e ciencias da computação ( CWI, sigle holandesa) sede Holanda.&lt;br /&gt;
Guido Van Rossum é o principal autor da linguagem Python e nasceu em 1956 na Holanda e em meados de 2005 foi contratado como desenvolvedor Google Inc, onde atualmente trabalha.&lt;br /&gt;
O nome da linguagem de programação foi baseada na admiração de seu criador pelos humoristas britanicos do Monty Python, uma série de televisão de sucesso em 1969 e 1974.&lt;br /&gt;
O site oficial da linguagem é www.python.org e lá podemos encontrar o link download para a versão mais recente da linguagem em todo tipo de plataforma.&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Instalando o Python&lt;/b&gt;&lt;br /&gt;
Antes de começar a programar vamos instalar primeiro o interpretador python, que é a linguagem em sí. &lt;br /&gt;
Digite os seguintes comandos no terminal para instalar o pacote (Linux): &lt;br /&gt;
&lt;br /&gt;
sudo apt-get install python 3.4.0&lt;br /&gt;
&lt;br /&gt;
Vamos instalar um outro pacote para nos auxiliar durante o processo de programação, vamos instalar a interface gráfica. &lt;br /&gt;
&lt;br /&gt;
sudo apt-get install idle-python 3.4.0&lt;br /&gt;
&lt;br /&gt;
para abrir usamos os seguintes comandos no terminal:&lt;br /&gt;
&lt;br /&gt;
idle-python3.4.0 &amp;amp;&lt;br /&gt;
&lt;br /&gt;
Observe que o &amp;amp; (&quot;i comercial&quot;) é apenas para liberar o terminal depois de abrir a interface gráfica. &lt;br /&gt;
&lt;br /&gt;

A linguagem C foi criada em 1972 no Bell Telephone Laboratories por Dennis Ritchie com a finalidade de permitir a escrita de um sistema operacional(o Unix), ultilizando uma linguagem de relativo alto nível, evitando assim o recurso ao Assembly.&lt;br /&gt;
Devido às suas capacidades através da divulgação do sistema Unix pelas universidades dos Estados Unidos, a linguagem C deixou cedo as portas dos laboratórios Bell, disseminou-se e tornou-se conhecida por todos os tipos de programadores, independentemente dos projetos em que estivessem envolvidos, sendo o livro&lt;i&gt; The C Programming Language,&lt;/i&gt; de Kernighan &amp;amp;&amp;nbsp; Ritchie, o único elo comum entre os programadores.&lt;br /&gt;
Essa dispersão levou a que diferentes organizações desenvolvessem e ultilizassem diferentes versões da linguagem C, criando assim alguns problemas de portabilidade, entre outros. Diante de tal estade de coisas, e uma vez que a linguagem C se tinha tornado um verdadeiro fenômeno entre os programadores e organizações, o American National Standards Institute (ANSI) formou em 1983 um comitê para a definição de um padrão da linguagem C, padrão esse que visa ao funcionamento semelhante de todos os compiladores da linguagem, com especificações muito precisas sobre aquilo que a linguagem deve ou não fazer, seus limites, definições, etc.&lt;br /&gt;
O nome da linguagem( e a própria linguagem) resulta da evolução de uma outra linguagem de programação desenvolvida por Ken Thompson também nos Laboratórios Bell, chamada de B. Dessa forma, é perfeitamente natural que a evolução da linguagem B desse origem à linguagem C.&lt;br /&gt;
&lt;br /&gt;
Qual a área de desenvolvimento C se destina?&lt;br /&gt;
&lt;i&gt;Nenhuma em particular&lt;/i&gt;. É muitas vezes denominada de &lt;i&gt;general purpose&lt;/i&gt;, que é uma das suas grandes vantágens, pois adapta-se aos desenvolvimento de qualquer projeto, como sistemas operacionais, interfaces gráficas, processamento de registro, etc. A linguagem C é até mesmo ultilizada pra escrever os compiladores de outras linguagens.&lt;br /&gt;
&lt;br /&gt;A filosofia da linguagem C é uma pouco parecida com a do Unix, incorporando, aliás, algumas das suas características( &lt;i&gt;case sensitive&lt;/i&gt;, por exemplo).&lt;br /&gt;

O compilador de Fortran da intel® tem suporte para o padronizado mecanismo do Fortran 2003 que parmite o código em Fortran se cominicar de forma confiável (ou interoperar) com um código em C. &lt;br /&gt;
&lt;i&gt;&amp;nbsp;&lt;/i&gt;&lt;i&gt;Como chamar um programa em C a partir de um em fortran e como chamar um programa fortran a partir de um em C&lt;/i&gt;, tema de hoje. &lt;br /&gt;
&lt;br /&gt;
Para chamar funções em c a partir de um programa Fortran ou chamar subrotinas em Fortran a partir de C envolve resolver as seguintes problemas:&lt;br /&gt;
&lt;br /&gt;
* &#39;Case sensitivity&#39; ( uma vez que C é &#39;case sensitive&#39; porém fortran não é)&lt;br /&gt;
* Possivel sublinhado adicional (&quot;_&quot;) em nomes de funções em C (o&lt;br /&gt;
&amp;nbsp;&amp;nbsp; sublinhado é adicinado por alguns compiladores em fortran.)&lt;br /&gt;
* Possiveis bibliotecas adicionais em Fortran que precisam ser linkadas para&lt;br /&gt;
&amp;nbsp;&amp;nbsp; construir executáveis.&lt;br /&gt;
* Subrotinas em fortran são sempre &quot;chamadas por referência&quot; enquanto&lt;br /&gt;
&amp;nbsp;&amp;nbsp; em C podem ser tanto &quot;por referência quando por valor&quot;. &lt;br /&gt;
&lt;br /&gt;
No que se segue, especificos exemplos são dados para compiladores intel e compiladores GNU. Se vc está usando outro compilador mudanças podem ser requeridas.&lt;br /&gt;
&lt;h3&gt;
C chamando subrotinas em fortran suboutines&lt;/h3&gt;
&lt;pre&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;span style=&quot;font-family: Arial,Helvetica,sans-serif;&quot;&gt;Exemplo de programas em C. Programa principal (c-call-f.c) -- note o sublinhado arrastado&lt;/span&gt;&lt;/span&gt;&lt;/pre&gt;
&lt;pre&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;span style=&quot;font-family: Arial,Helvetica,sans-serif;&quot;&gt;no nome da função for_sub_:&lt;/span&gt;&lt;/span&gt;&lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;#include &lt;stdio .h=&quot;&quot;&gt;
void for_sub_(int *, double *, double *, int *);
int main()
{
int i = 1, ny = 3;
double pi = 3.14159;
double y[] = {1.1, 2.2, 3.3};
// pular uma linha para melhor visualizacao
printf(&quot;\n&quot;);
printf(&quot;_____________________________________________\n&quot;);
printf(&quot; C chamando subrotina em fortran, passando\n&quot;);
printf(&quot; i = %d, pi = %g\n&quot;, i, pi);
printf(&quot; y[] = %g, %g, %g\n&quot;, y[0], y[1], y[2]);
printf(&quot;_____________________________________________&quot;);
//pular uma linha para melhor visualizacao
printf(&quot;\n&quot;);
for_sub_(&amp;amp;i, &amp;amp;pi, y, &amp;amp;ny);
return 0;
}
&lt;/stdio&gt;&lt;/pre&gt;
&lt;br /&gt;
Programa exemplo: subrotina em fortran, em &quot;formato livre (free format)&quot; ( f_sub.f) &lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;subroutine FOR_SUB(i, pi, y, ny)&lt;br /&gt;IMPLICIT NONE&lt;br /&gt;integer :: i, ny&lt;br /&gt;double precision :: pi&lt;br /&gt;double precision :: y(ny)&lt;br /&gt;! pular uma linha para melhor visualizacao no terminal&lt;br /&gt;print *, &quot; &quot;&lt;br /&gt;print *, &quot;____________________________________________&quot;&lt;br /&gt;print *, &quot;Esta eh uma subrotina em Fortran...&quot;&lt;br /&gt;print *, &quot;i = &quot;, i, &quot;, pi = &quot;, pi&lt;br /&gt;print *, &quot;y = &quot;, y(1:ny)&lt;br /&gt;print *, &quot;____________________________________________&quot;&lt;br /&gt;! pular uma linha para melhor visualizacao no terminal&lt;br /&gt;print *, &quot; &quot;&lt;br /&gt;end subroutine FOR_SUB&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
Como compilar:&lt;/h3&gt;
&lt;h4&gt;
&lt;code&gt;&lt;/code&gt;&lt;code&gt;Usando compiladores Intel icc e ifort&lt;/code&gt;&lt;/h4&gt;
&lt;pre&gt;$ icc -c c-call-f.c
$ ifort -free -c f_sub.f
$ icc -o c-call-f-icc  c-call-f.o  f_sub.o -L/u/local/&lt;/pre&gt;
&lt;pre&gt;compilers/intel/fce/current/lib -lifcore -limf
$ ./c-call-f-icc
&lt;/pre&gt;
&lt;h4&gt;
Usando compiladores GNU gcc e gfortran &lt;/h4&gt;
&lt;pre&gt;$ gcc -c c-call-f.c
$ gfortran -ffree-form -c f_sub.f
$ gcc -o c-call-f-gcc  c-call-f.o f_sub.o  -lgfortran
$ ./c-call-f-gcc&amp;nbsp;
&lt;/pre&gt;
&lt;h3&gt;
Fortran chamando funções em C &lt;/h3&gt;
Exemplo de programa: Programa principal em fortran,&lt;br /&gt;
em free format 
(&lt;code&gt;f-call-c.f&lt;/code&gt;):

&lt;br /&gt;
&lt;br /&gt;
&lt;pre&gt;program f_call_c&lt;/pre&gt;
&lt;pre&gt;IMPLICIT none &lt;/pre&gt;
&lt;pre&gt;integer :: i = 1, ierr
double precision :: pi = 3.14159 &lt;/pre&gt;
&lt;pre&gt;print *, &quot;______________________________&quot; &lt;/pre&gt;
&lt;pre&gt;print *, &quot;Fortran chamando C, passando&quot;
print *, &quot;i = &quot;, i, &quot;pi = &quot;, pi
ierr = cfun(i, pi)&lt;/pre&gt;
&lt;pre&gt;print *, &quot;______________________________&quot;&lt;/pre&gt;
&lt;pre&gt;end program f_call_c&lt;/pre&gt;
&lt;br /&gt;
&lt;pre&gt;&lt;span style=&quot;font-family: Arial,Helvetica,sans-serif;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Programa exemplo: função em C(cfun_c) -- note que o sublinhado arrastado no nome da&lt;/span&gt;&lt;/span&gt;&lt;/pre&gt;
&lt;pre&gt;&lt;span style=&quot;font-family: Arial,Helvetica,sans-serif;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;função cfun:&lt;/span&gt;&lt;/span&gt;&lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;#include &lt;stdio .h=&quot;&quot;&gt;
int cfun_(int *ip, double *xp)
{
int i = *ip;
double x = *xp;&lt;/stdio&gt;&lt;/pre&gt;
&lt;pre&gt;printf(&quot;\n&quot;);&lt;/pre&gt;
&lt;pre&gt;printf(&quot;______________________________&quot;); &lt;/pre&gt;
&lt;pre&gt;printf(&quot;Esta eh uma funcao em C...\n&quot;);
printf(&quot;i = %d, x = %g\n&quot;, i, x);&lt;/pre&gt;
&lt;pre&gt;printf(&quot;______________________________&quot;);&lt;/pre&gt;
&lt;pre&gt;printf(&quot;\n&quot;); &lt;/pre&gt;
&lt;pre&gt;return 0;
}&lt;/pre&gt;
&lt;h3&gt;
Como se compilar&lt;/h3&gt;
&lt;h4&gt;
Usando compiladores Intel &lt;code&gt;icc&lt;/code&gt; and &lt;code&gt;ifort&lt;/code&gt;&lt;/h4&gt;
$ ifort -free -c f-call-c.f
$ icc -c cfun.c&lt;br /&gt;
$ ifort -o f-call-c-icc f-call-c.o cfun.o
$ ./f-call-c-icc



&lt;br /&gt;
&lt;h4&gt;
Usando compiladores GNU &lt;code&gt;gcc&lt;/code&gt; and &lt;code&gt;gfortran&lt;/code&gt;&lt;/h4&gt;
$ gfortran -ffree-form -c f-call-c.f&lt;br /&gt;
$ gcc -c cfun.c&lt;br /&gt;
$ gfortran -o f-call-c-gcc f-call-c.o cfun.o&lt;br /&gt;
$ ./f-call-c-gcc
&lt;br /&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;

&lt;br /&gt;
É de praxe que é a gravidade que nos mantem &quot;grudados&quot; ao nosso planeta. Apesar dela ser a mais fraca entre as quatro forças fundamentais da natureza, ela também se estende a toda a Via Láctea, evitando que se disperssem os bilhões e bilhões de estrelas, as incontáveis moléculas e particulas isoladas que de distribuem ao longo de nossa relativamente colossal galáxia.&lt;br /&gt;
&lt;br /&gt;
A força gravitacional se estende ao espaço intergalático, mantendo unidas as galáxias do Grupo Local, que inclui, além da Via Láctea, a nossa vizinha Andrômeda, as várias galáxias anãs mais próximas, tais como, a satélite galáxia, a grande Núvem de Magalhães. O Grupo Local citado faz parte do Super Aglomerado Local de Galáxias está atraído pela força gravitacional para uma região do espaço, excepcionalmente densa, mais conhecida como Grande Atrator. A força gravitacional se estende ainda mais longe, já que tenta manter unido todo o Universo, que está se expandindo.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
A força da gravidade também é responsável por uma das entidades mais misteriosas do universo, o buraco negro. Quando uma estrela consideravelmente maior que o Sol se apaga, a força gravitacional entre suas partículas pode fazer com que a estrela se contraia indefinidamente, formando um buraco negro.&lt;br /&gt;
&lt;br /&gt;
A senhora da matéria na superficie de uma estrela desse tipo é tão intensa que nem a própria luz pode escapar, por isso o nome buraco negro.&lt;br /&gt;
&lt;br /&gt;
Mesmo hoje a força da gravidade não está totalmente compreendida mas o grande Isaac Newton deu o ponta pé inicial para o intendimento que temos hoje sobre uma coisa que ninguém sabe exatamente o que é mas que chamamos de gravidade.&lt;br /&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;

&lt;br /&gt;
&lt;br /&gt;
Sistema de Pitolomeu: O sistema geocentrico de ptolomeu sobreviveu por 1400 anos guiando a filosofia, a ciencia e a religiaão. Nesse periodo, a sociedade assistiu a acessão e queda do império romana, as invasões barbaras e a formação de uma sociedade feudal, dominada pela igreja católica.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;NIcolau copernico, um padre nascido na polônia.&lt;br /&gt;
&lt;br /&gt;
Entre os séculos XV e XVI viveu Nicolau Copérnico(1473-1543), astrônomo polonês que contestou as idéias de Aristólteles ao propor, como &lt;b&gt;Aristarco de Samos&lt;/b&gt;, o sistema heliocêntrico.&lt;br /&gt;
A teoria heliocentrica de Copérnico foi posteriormente modificada, pois apresentava falhas, que alguns cientistas trataram como corrigir. Deixando de lado esse aspecto,a grandeza desse pensador não está tanto no sistema de universo que propôs, mas no fato de que suas ideias foram a semente da grande revolução científica do século XVII, iniciada por galileu.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; Anos depois, um jovem filosofo e frade dominicano chamado Geordano Bruno expandiu a ideia de copernico acreditando em um universo infinito, sem limites em que a terra girava em torno do Sol e as estrelas eram centros de outros sistemas planetário. Acabou queimado na fogueira em 1600.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;Poucos anos depois Galileu aperfeiçoou o telescópio holandez , descobriu quatro luas de Jupiter, aneis de saturno, manchas solares , crateras e montanhas da lua, descobriu assim que o ceu não é tão divino. Foi condenado a prisão perpétua ao deixar o tribunal, dizem que falou: Epur si mouve, e contudo, ela se move.&lt;br /&gt;
&lt;br /&gt;
O astronomo dinamarquês Tycho Brahe durante mais de 20 anos observou as orbitas dos planetas até então conhecidos. Usandos dados conseguidos por Brahe, o astronomo alemão, Johannes Kepler coletou esses dados e percebendo que neles haviam certas regularidades elaborou três leis que descreveria completamento o movimento de todos os planetas ao redor do Sol.&lt;br /&gt;
Primeira Lei:&lt;br /&gt;
A orbita dos planetas não é uma orbita circular, como se acreditava até então, e sim eliptica e o Sol ocupa um dos focos dessa elipse e o outro foco, obviamente, é vazio.&lt;br /&gt;
&amp;nbsp;Segunda Lei:&lt;br /&gt;
A linha que uni o planeta ao Sol varre áreas iguais em tempos iguais. A consequência disso é que os planetas aceleram quando estão mais próximo do Sol.&lt;br /&gt;
Terceira Lei:&lt;br /&gt;
&lt;br /&gt;
Essa constante depende do corpo central na qual o planeta está orbitando e não depende da massa do planeta.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Vale ressaltar que as Leis de Kepler não servem apenas para descrever o movimento de planetas ao redor do Sol e sim descrever o movimento de qualquer corpo em orbita do outro de massa maior.&lt;br /&gt;
Exemplos clássicos disso são o da Lua ao redor da Terra, de satélites artificiais ao redor do nosso planeta de estrelas orbitando estrelas, etc.&lt;br /&gt;
&lt;br /&gt;
Mais tarde, Isaac Newton percebeu que as três Leis de Kepler, juntamente com as ideias e descobertas de Galileu, poderiam ser unificadas em uma só lei, que ele chamou de Lei da Gravitação Universal. Era a forma para o entendimento do cosmos, que deixava de ser puru e divino e ganhava a dimensão das coisas terrenas, passando a ser assim natural, uma extensão da terra, ou seja, as leis que se aplicavam na terra, poderiam ser aplicadas no céu. &lt;br /&gt;
&lt;br /&gt;
Enunciado da gravitação universal.&lt;br /&gt;
&lt;br /&gt;
ou seja, quanto maior a massa do objeto e menor a distância entre eles, maior a força gravitacional entre eles. Essa atraçao garante estabilidade e evolução do universo, sendo a gravitação a causa da movimentação dos planetas.&lt;br /&gt;
&lt;br /&gt;
Anos depois nasce Eistein e concluir que não seria apenas isso. A deformaçao do próprio espaço tempo. A primeira Lei de Newton diz que um corpo viaja em linha reta a não ser que uma força ou um conjunto de forças atue sobre ele. Depois de Eistein trajetórias retilínias passam a ser curvilínias pela simples deformação do espaço, e assim acontece a atração gravitacional, não mais uma força, como propunha Newton e sim a própria deformação do espaço-tempo causada pela presença da matéria. Tempo e espaço são uma coisa só, a grande sacada de Eistein.&lt;br /&gt;
&lt;br /&gt;

1 hertz = 1 Hz = 1 oscilação por segundo = 1/s&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuY09CUi8TV7baRpOTfTsGzVWFWQxenJfClpSJov7tkWaIr6wMMLBHbXdSZPTAs0G6gOhelard7cBdaOywGa5EjAt3t7o6WmNL8_6ry5T88NNKxWJnxSmj0x2SV3uqElMy_qVzVb9FXhb5/s1600/mhs_234234.gif&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuY09CUi8TV7baRpOTfTsGzVWFWQxenJfClpSJov7tkWaIr6wMMLBHbXdSZPTAs0G6gOhelard7cBdaOywGa5EjAt3t7o6WmNL8_6ry5T88NNKxWJnxSmj0x2SV3uqElMy_qVzVb9FXhb5/s1600/mhs_234234.gif&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;br /&gt;
Uma grandeza relacionada a frequência é o período T do movimento. &lt;b&gt;O período&lt;/b&gt; de alguma coisa é o tempo necessário pra completar uma oscilação ou um ciclo.&lt;br /&gt;
&lt;br /&gt;
&lt;i&gt;&lt;u&gt;Exemplo&lt;/u&gt;&lt;/i&gt;: &lt;i&gt;Podemos dizer que a Terra tem um período de 365,25 dias para completar o seu ciclo ou período anual.&lt;/i&gt;&lt;br /&gt;
&lt;i&gt;&lt;br /&gt;&lt;/i&gt;
&lt;i&gt;&lt;br /&gt;&lt;/i&gt;
&lt;br /&gt;
O tipo de movimento que se repete em intervalos regulares e se repete em intervalos regulares é chamado de movimento periódico ou movimento harmônico.&lt;br /&gt;
&lt;br /&gt;
Nesse tópico, vamos estudar o tipo de movimento em que o deslocamento x da partícula em relação a origem é dado por uma função do tempo da forma:&lt;br /&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;b&gt;x(t) = x&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;m&lt;/span&gt;&lt;/span&gt; cos( ωt + &lt;span class=&quot;st&quot;&gt; ϕ&lt;/span&gt;)&amp;nbsp;&lt;/b&gt;&lt;br /&gt;
onde:&lt;br /&gt;
x&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;m,&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;&lt;b&gt; &lt;/b&gt;&lt;span style=&quot;font-size: small;&quot;&gt;ω e&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;b&gt;&lt;span class=&quot;st&quot;&gt; &lt;/span&gt;&lt;/b&gt;&lt;span class=&quot;st&quot;&gt;ϕ são constantes&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;x(t) = deslocamento&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;x&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;m&amp;nbsp; &lt;span style=&quot;font-size: small;&quot;&gt;=&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;amplitude&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;ω = frequência angular&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;/span&gt;&lt;span class=&quot;st&quot;&gt;ϕ = constante de fase ou ângulo de fase&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&amp;nbsp;&lt;/span&gt;( ωt + &lt;span class=&quot;st&quot;&gt; ϕ&lt;/span&gt;) = fase&lt;b&gt; &lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;São essas grandezas que determinam a forma de um gráfico&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;b&gt;&lt;/b&gt;
&lt;span class=&quot;st&quot;&gt;A esse movimento damos o nome de movimento harmônico símples ou MHS. Essa é uma expressão que significa que o movimento periódico é uma função senoidal do tempo.&lt;/span&gt;&lt;b&gt;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
A grandeza&lt;b&gt; &lt;/b&gt;&lt;span class=&quot;st&quot;&gt;&lt;b&gt;x&lt;/b&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;&lt;b&gt;m &lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;b&gt;&lt;span class=&quot;st&quot;&gt;denominada&lt;/span&gt; amplitude&lt;/b&gt; do movimento, é uma constante positiva cujo valor depende do modo como o movimento foi produzido. O indice &#39;m&#39; indica valor máximo, que que a amplitude representa o deslocamento máximo da partícula em um dos sentidos.&lt;br /&gt;
&lt;br /&gt;
( ωt + &lt;span class=&quot;st&quot;&gt; ϕ&lt;/span&gt;) é chamada de fase do movimento e a constante &lt;b&gt;&lt;span class=&quot;st&quot;&gt; &lt;/span&gt;&lt;/b&gt;&lt;span class=&quot;st&quot;&gt;ϕ é chamada de constante de fase ou ângulo de fase. O valor&amp;nbsp;&lt;/span&gt;&lt;b&gt;&lt;span class=&quot;st&quot;&gt; &lt;/span&gt;&lt;/b&gt;&lt;span class=&quot;st&quot;&gt;ϕ depende do deslocamento da velocidade da partícula no instante t = 0.&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;Para interpretar a constante&amp;nbsp; &lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;ω &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;st&quot;&gt;o da , denominada frequência ângular do movimento. Note que o deslocamento x(t) deve ser igual a x(t+T) para qualquer valor de t.&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;Para simplificar a análise, fazemos&amp;nbsp; &lt;/span&gt;&lt;span class=&quot;st&quot;&gt;ϕ = 0.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&lt;b&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/b&gt;x&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;m&lt;/span&gt;&lt;/span&gt; cos(ωt) =&amp;nbsp;&lt;/span&gt;&lt;b&gt; &lt;/b&gt;x&lt;span style=&quot;font-family: &amp;quot;Courier New&amp;quot;,Courier,monospace;&quot;&gt;&lt;span style=&quot;font-size: xx-small;&quot;&gt;m&lt;/span&gt;&lt;/span&gt; cos&lt;span class=&quot;st&quot;&gt;[ω&lt;/span&gt;(t + T)]&lt;b&gt;&lt;span class=&quot;st&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/b&gt;&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;A função co-seno se repete pela primeira vez quando seu argumento, que é a fase, aumenta em 2&lt;/span&gt;π,&lt;br /&gt;
Assim&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; ω&lt;/span&gt;(t + T)&amp;nbsp; = &lt;span class=&quot;st&quot;&gt;ω&lt;/span&gt;t + 2π&lt;br /&gt;
&lt;span class=&quot;st&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; ω&lt;/span&gt;T = 2π&lt;br /&gt;
Assim, de acordo com T = 1/f&lt;br /&gt;
&amp;nbsp;&lt;span class=&quot;st&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; ω = &lt;/span&gt;2π/T = 2πf&lt;br /&gt;
A unidade de frequência angular no SI é o radiano por segundo e por coerência&amp;nbsp; &lt;span class=&quot;st&quot;&gt;ϕ deve ser expresso em radianos.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;h4&gt;

Os pinos digitais são esses dois blocos pretos do lado esquerdo da figura numerados de 0 a 13.&lt;br /&gt;
Os pinos digitais no arduino podem ser configurados tanto como entrada ou saida. É importante notar que a maioria dois pinos analógicos do arduino podem ser configurados e usados exatamente da mesma maneira que os pinos digitais, note também que quando falamos dos pinos do arduino estamos falando dos pinos do Atmega, que é o microcontrolador que vem no hardware do arduino.&lt;br /&gt;

&lt;pre&gt;normalmente vamos precisar rodar,primeiramente, o comando&lt;/pre&gt;
&lt;pre&gt;&#39;sudo updatedb&#39; (que vem de update database) para atualizarmos&lt;/pre&gt;

&lt;br /&gt;
&lt;span style=&quot;font-size: small; line-height: 22px;&quot;&gt;&lt;span style=&quot;color: black; font-family: arial, sans-serif;&quot;&gt;Se o seu navegador está apresentando algum &lt;b&gt;erro relacionado a proxy&lt;/b&gt; e você não está conseguindo&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small; line-height: 22px;&quot;&gt;&lt;span style=&quot;color: black; font-family: arial, sans-serif;&quot;&gt;acessar a alguns ou nenhum site, talvés ele esteja configurado para acessar a páginas por meio de um servidor&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small; line-height: 22px;&quot;&gt;&lt;span style=&quot;color: black; font-family: arial, sans-serif;&quot;&gt;proxy. Um servidor proxy serve para intermedir a sua conexão com o servidor, que é a sua página. Porém se ele estiver configurado errado ou mesmo usar sem necessidade, certamente o seu navegador não consiguirá acessar a diversos sites do mundo web. &lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-size: small; line-height: 22px;&quot;&gt;&lt;span style=&quot;color: black; font-family: arial, sans-serif;&quot;&gt;Segue abaixo os passos para resolver este problema:&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;ol&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Clique no menu do Google Chrome na barra de ferramentas do navegador.&lt;/li&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Selecione&amp;nbsp;&lt;b style=&quot;font-family: inherit; font-style: inherit; outline: 0px;&quot;&gt;Configurações&lt;/b&gt;.&lt;/li&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Clique em&amp;nbsp;&lt;b style=&quot;font-family: inherit; font-style: inherit; outline: 0px;&quot;&gt;Mostrar configurações avançadas&lt;/b&gt;.&lt;/li&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Na seção &quot;Rede&quot;, clique em&amp;nbsp;&lt;b style=&quot;font-family: inherit; font-style: inherit; outline: 0px;&quot;&gt;Alterar configurações de proxy&lt;/b&gt;. Isso abrirá a caixa de diálogo &quot;Propriedades de internet&quot;.&lt;/li&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;Clique em&amp;nbsp;&lt;b style=&quot;font-family: inherit; font-style: inherit; outline: 0px;&quot;&gt;configurações de LAN&amp;nbsp;&lt;/b&gt;.&lt;/li&gt;
&lt;li style=&quot;border: 0px; font-family: inherit; font-style: inherit; margin: 0px 0px 0px 2em; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;&lt;b&gt;Desmarque&lt;/b&gt;&amp;nbsp;todas as caixas de seleção, salve e reinicie seu navegador.&amp;nbsp;&lt;/li&gt;
&lt;/ol&gt;
&lt;br /&gt;
&lt;i&gt;&lt;b&gt;Se mesmo assim não resolveu&lt;/b&gt;&lt;/i&gt;&lt;b&gt; tente o seguinte&lt;/b&gt;, caso esteja no ambiente windows:&lt;br /&gt;
&lt;br /&gt;
&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311194391=298815b7069e159f128.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;1. Pressionem a combinação de teclas Windoes + R e digitem: &quot;gpedit.msc&quot;&lt;/span&gt;&lt;/span&gt; &lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311238985=202e64ea81ca1ea2490.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;a tecla windows é aquela tecla perto do espaço que tem o símbolo do windows&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;br /&gt;
&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311254589=240aa2465203fc65382.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311273255=2fce64ce4e30029f531.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;3. Na
 janela que se abre, dê duplo clique em &quot;Configuração de Usuário / 
Modelos Administrativos / Componentes do Windows / Internet Explorer&quot;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311273255=2fce64ce4e30029f531.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&quot;_5yl5&quot; data-reactid=&quot;.4l.$mid=11406311290185=27a19977b993b786c68.2:0.0.0.0.0&quot;&gt;&lt;span class=&quot;null&quot;&gt;4. Dê um duplo clique em &quot;Desabilitar o cache de scripts de Proxy Automático&quot;
Marque [Habilitar] e dê [OK]&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;

&lt;pre&gt;Existem várias formas de instalar o flashplayer para rodar&lt;/pre&gt;
&lt;pre&gt;os mais diversos videos da web em seu browser. Segue&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;abaixo o modo mais símples e geral para resolver os seus&lt;/pre&gt;
&lt;pre&gt;problemas quando estiver tentando fazer isto&lt;b&gt; no ambiente linux.&lt;/b&gt;&lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;&lt;b&gt;Abra o terminal e digite os comandos:&lt;/b&gt; &lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;sudo apt-get install flashplugin-nonfree
update-flashplugin-nonfree --install&lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;&lt;b&gt;Reinicie seu navegador e pronto.&lt;/b&gt;&lt;/pre&gt;
&lt;pre&gt;&amp;nbsp;&lt;/pre&gt;
&lt;pre&gt;Abra o seguinte site e &lt;b&gt;se a animação na parte superior estiver&amp;nbsp;&lt;/b&gt;&lt;/pre&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Neste tópico, como exemplo, vamos fazer o sistema ler seu pen drive e listar as informações que o sistema teve dele.&lt;br /&gt;
Siga os seguintes passos:&lt;br /&gt;
&lt;br /&gt;
Plugue o pendrive&lt;br /&gt;
Abra o&amp;nbsp; terminal
(como root)&lt;br /&gt;
&lt;br /&gt;
Digite no terminal: &lt;br /&gt;
fdisk -l (L minúsculo)&lt;br /&gt;
&lt;br /&gt;
Esse comando vai mostrar as partições detectadas,&lt;br /&gt;
inclusive o seu pen drive&lt;br /&gt;
Algo tipo isso: &lt;br /&gt;

Olá a todos&lt;br /&gt;
&lt;br /&gt;Estou iniciando uma série de posts relacionado ao grande sistema operacional linux e neste primeiro tópico vou mostrar como formatar um pen drive dentro desse SO.&lt;br /&gt;
&lt;br /&gt;
A distribuição que eu realizei este tuturial foi o kali linux, mas você pode fazer isso em qualquer outra distribuição. Eu também usei o gparted, que é nativo nesta distro.&lt;br /&gt;
&lt;br /&gt;
O primeiro passo é&amp;nbsp; abrir o terminal e digitar &quot;gparted&quot;&lt;br /&gt;
&lt;br /&gt;
No GParted, tu vai ver a partição do pendrive.&lt;br /&gt;
Simplesmente deleta e cria outra, do tipo vfat ou fat32 (mesma coisa).&lt;br /&gt;
Se funcionar, depois é só checar a integridade da partição e devolver o pendrive.</content><link rel='replies' type='application/atom+xml' href='http://cienciaemtodaparte.blogspot.com/feeds/8778704614040346756/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2014/07/como-formatar-um-pen-drive-no-linux.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/8778704614040346756'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/8778704614040346756'/><link rel='alternate' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2014/07/como-formatar-um-pen-drive-no-linux.html' title='Como formatar um pen drive no linux'/><author><name>Claudemir</name><uri>http://www.blogger.com/profile/01857471365638258794</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhDBLsp6mGh9p5h4D6JL1_utqCq8USY-JSl9LN__KcTcoClFNhytaQ1NK8dYKP57tPnvTUtDIbuBrJPqd9vcTvQVh5kyehMemQmd8r0DGnNgNSdtnZsy9TC4V2PTvRXJ4aw30qCL2UuL5D2/s72-c/usb_cienciaemtodaparte.png" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3320023355260357600.post-8354121119149244969</id><published>2013-07-31T16:07:00.001-07:00</published><updated>2013-07-31T16:15:29.981-07:00</updated><title type='text'>Um pouco da história de Bill Gates</title><content type='html'>&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

Olá pessoal! &lt;br /&gt;
No conteúdo do link abaixo retrata-se um pouco da vida desse homem que é tão criticado, mas é um verdadeiro exemplo de empreendedor. O homem mais rico do mundo não planejou isso da noite para o dia, mas sua história mostra que esses planos vieram muito cedo...&lt;br /&gt;

Moore&lt;/span&gt; fez sua  &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_0&quot;&gt;famosíssima&lt;/span&gt; profecia, na qual o número de &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_1&quot;&gt;transistores&lt;/span&gt; dos chips teria um aumento de  100%, pelo mesmo preço, a cada período de 18 meses. Essa profecia  tornou-se realidade e acabou ganhando o nome de &lt;b&gt;Lei de Moore&lt;/b&gt;.  Esta serve de modelo para um gigantesco número de dispositivos digitais,  além de &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_2&quot;&gt;CPUs&lt;/span&gt;. Na verdade, qualquer chip está ligado a lei de Moore, até  mesmo &lt;a href=&quot;http://pt.wikipedia.org/wiki/CCD&quot; title=&quot;CCD&quot; class=&quot;mw-redirect&quot;&gt;&lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_3&quot;&gt;CCD&lt;/span&gt;&lt;/a&gt;  de &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_4&quot;&gt;câmeras&lt;/span&gt; fotográficas digitais (sensor que capta a imagem nas &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_5&quot;&gt;câmeras&lt;/span&gt;  nuclear; ou &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_6&quot;&gt;CNCL&lt;/span&gt;, sensores que captam imagens nas &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_7&quot;&gt;câmeras&lt;/span&gt; fotográficas  &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_8&quot;&gt;profissionais&lt;/span&gt;). Esse padrão se manteve e não espera-se mudanças até mais ou menos 2015.&lt;br /&gt;&lt;br /&gt;Muita coisa ainda vai mudar e certamente a Lei de Moore não valerá mesmo pois quando, e será não &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_9&quot;&gt;muio&lt;/span&gt; distante, for desenvolvido computadores &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_10&quot;&gt;quanticos&lt;/span&gt; a coisa irá variar &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_11&quot;&gt;bastate&lt;/span&gt; pois, estaremos lidando com um mundo novo.

&quot;hoje eu estou apenas com uns dez por cento de disposição&quot;. &quot;Eu estou cheio de amor pra dar&quot;...As alegações são as mais diversas. O problema é que: amor; felicidade; paixão; disposição...&lt;span style=&quot;font-weight: bold;&quot;&gt; não podem ser medidos ou seja, não são grandezas físicas.&lt;/span&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;font-weight: bold;&quot;&gt;Grandeza física é tudo que pode ser medido e assim representado por um número e uma unidade.&lt;/span&gt; Assim, qual seria a unidade de amor ou de paixão que poderia uma pessoa ter em determinado momento? Nenhuma, pois não são grandezas físicas.&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;Um lugar onde poderíamos encontrar as mais diversas formas de grandezas seria se &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_0&quot;&gt;estivéssemos&lt;/span&gt; em um jogo de futebol. Uma bola deve ter entre 400 e 500 gramas e deve está a 9,15 metros da barreira e a partida deve durar 90 minutos. Temos nesse caso três grandezas físicas. A grandeza da bola é a massa e a unidade ( o número que representa essa grandeza) o grama. No caso da barreira em posição a bola, a grandeza física é a distância e a unidade o metro. E por último a duração do jogo. A grandeza física que representa a duração de qualquer coisa é o tempo e a unidade o segundo. Massa, distância e tempo são exemplos de grandezas físicas fundamentais. &lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;Existe outras grandezas muito usadas no nosso dia-a-dia. Digamos que você queira comprar uma casa. Uma das coisas que mais vai te interessar será a área. Uma das unidades da área é o metro quadrado (m²) que vem do metro. Digamos que um participante de uma corrida de carroças de burro percorreu 50 km em 2 horas ou seja, sua velocidade média é de 25 km/h. A velocidade é definida a partir da distância pelo tempo, duas grandezas fundamentais. A unidade é o km/h. Como a velocidade surge à partir de duas grandezas fundamentais, essa é considerada uma grandeza derivada. &lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;Uma grandeza derivada, como por exemplo a velocidade, possui, também, uma unidade derivada. O metro quadrado (m²) é derivado do metro; O km/h deriva-se do metro e do segundo. Existe outras grandezas derivadas também: a força, a aceleração, a densidade etc.&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;As sete grandezas fundamentais estabelecidas pelo Sistema Internacional de medidas (SI) são: O comprimento, massa, tempo, corrente elétrica, temperatura, quantidade de matéria e intensidade luminosa. Existem unidades que fazem parte do SI ( arrobas, jardas, braças...) então é bom ficar ligado.&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt;Estarei publicando aqui em breve algumas coisas relacionadas em um futuro breve, por isso fiquem atentos e não esqueça de seguir o blog ou no twitter ou facebook.&lt;br /&gt;&lt;/p&gt;  &lt;p class=&quot;MsoNormal&quot;&gt; &lt;/p&gt;</content><link rel='replies' type='application/atom+xml' href='http://cienciaemtodaparte.blogspot.com/feeds/301324111790851287/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2011/11/grandezas-fisicas.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/301324111790851287'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/301324111790851287'/><link rel='alternate' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2011/11/grandezas-fisicas.html' title='Grandezas Físicas'/><author><name>Claudemir</name><uri>http://www.blogger.com/profile/01857471365638258794</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg1yFEYhIcJNPpfSmG2PMN17n-pkHXrn4P3AIQqZvyl0C5Er1Chs9stEl946IPqqbgeIvHGw02NupvjJRnS5UM7c7REbp9K2IrT91HJise8rLcscYK1lMJE8lie-KHQ5yuMeShYXZ2karvO/s72-c/magnitude.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3320023355260357600.post-5361906172536648787</id><published>2011-11-14T04:09:00.000-08:00</published><updated>2011-11-14T04:40:43.954-08:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="Ciências"/><category scheme="http://www.blogger.com/atom/ns#" term="curiosidades"/><category scheme="http://www.blogger.com/atom/ns#" term="física"/><title type='text'>Um pouco da História da Ciência</title><content type='html'>&lt;a onblur=&quot;try {parent.deselectBloggerImageGracefully();} catch(e) {}&quot; href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCoi37DwiMznvd8bJ6i3I1Q_ZNcRPdjlskvyEiuy2mWfmfBOHrtC8M2G8FGpZ-Z_9_xSMu68biGdNZhrF5RLqhNC-W6vFgVSemH9kvx28sCJSpMEby6uP7fFnU9f8schEcn3bygcxn7CZW/s1600/filosofia+natural.jpg&quot;&gt;&lt;img style=&quot;display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 224px;&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCoi37DwiMznvd8bJ6i3I1Q_ZNcRPdjlskvyEiuy2mWfmfBOHrtC8M2G8FGpZ-Z_9_xSMu68biGdNZhrF5RLqhNC-W6vFgVSemH9kvx28sCJSpMEby6uP7fFnU9f8schEcn3bygcxn7CZW/s400/filosofia+natural.jpg&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5674828584015875122&quot; border=&quot;0&quot; /&gt;&lt;/a&gt;&lt;br /&gt;Você já se perguntou o que é Física, Química, Astronomia, Biologia, Matemática...? Sua resposta poderia ser  a mais complexa ou &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_0&quot;&gt;técnica&lt;/span&gt; &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_1&quot;&gt;possível&lt;/span&gt;, hoje. Mas se você voltasse no tempo, pelo menos a duzentos anos, você não precisaria se &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_2&quot;&gt;preocupar&lt;/span&gt; com isso, pois todas &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_0&quot;&gt;essas&lt;/span&gt; áreas do conhecimento faziam parte de uma só: a Filosofia Natural.&lt;br /&gt;&lt;br /&gt;Com o passar do tempo as coisas construídas ou descobertas pelo homem aumentaram de tal &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_1&quot;&gt;maneira&lt;/span&gt; que foi preciso dividir o conhecimento em várias ciências.&lt;br /&gt;&lt;br /&gt;A invenção, por exemplo, da máquina a vapor e as descobertas sobre &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_2&quot;&gt;eletricidade&lt;/span&gt; fizeram surgir pessoas interessadas em aplicações práticas do conhecimento científico. Essas pessoas, que hoje chamamos de engenheiros, estavam mais interessados em tecnologia e daí abandonaram a Filosofia Natural.&lt;br /&gt;&lt;br /&gt;Os primeiros filósofos apareceram no século VI a.C nas &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_3&quot;&gt;colónias&lt;/span&gt; da Magna Grécia e da &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_4&quot;&gt;Jônia&lt;/span&gt;. Como na antiguidade a economia era baseada no trabalho escravo, o trabalho manual e as &lt;span class=&quot;blsp-spelling-error&quot; id=&quot;SPELLING_ERROR_5&quot;&gt;atividades&lt;/span&gt; práticas eram &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_6&quot;&gt;desprezadas&lt;/span&gt;. Dessa forma a filosofia se preocupava com assuntos inteiramente &lt;span class=&quot;blsp-spelling-corrected&quot; id=&quot;SPELLING_ERROR_7&quot;&gt;teóricos&lt;/span&gt;.&lt;br /&gt;&lt;br /&gt;A preocupação central desses pensadores  era explicar o universo; o tema básico de sua filosofia era de encontrar o princípio básico de todas as coisas. Antes os filósofos detinham conhecimento de praticamente tudo na ciência. Hoje a ciência está muitíssimo ampla que cada pessoa, na maioria das vezes, deve, apenas, se especializar em uma dessas áreas por vez. Hoje, literalmente, é impossível conhecer tudo, algo que um dia, já houve, pleno menos, a impressão de se conseguir.</content><link rel='replies' type='application/atom+xml' href='http://cienciaemtodaparte.blogspot.com/feeds/5361906172536648787/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2011/11/um-pouco-da-historia-da-ciencia.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/5361906172536648787'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/3320023355260357600/posts/default/5361906172536648787'/><link rel='alternate' type='text/html' href='http://cienciaemtodaparte.blogspot.com/2011/11/um-pouco-da-historia-da-ciencia.html' title='Um pouco da História da Ciência'/><author><name>Claudemir</name><uri>http://www.blogger.com/profile/01857471365638258794</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCoi37DwiMznvd8bJ6i3I1Q_ZNcRPdjlskvyEiuy2mWfmfBOHrtC8M2G8FGpZ-Z_9_xSMu68biGdNZhrF5RLqhNC-W6vFgVSemH9kvx28sCJSpMEby6uP7fFnU9f8schEcn3bygcxn7CZW/s72-c/filosofia+natural.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-3320023355260357600.post-3189971028532212052</id><published>2011-11-13T15:45:00.000-08:00</published><updated>2011-11-13T15:51:21.186-08:00</updated><title type='text'>Conheça a página do blog também no facebook</title><content type='html'>&lt;a onblur=&quot;try {parent.deselectBloggerImageGracefully();} catch(e) {}&quot; href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKZR7JmRwmJ-rsAqDnuPKNQZoUBk2N3GPUArBEiOk143SrD8GJpx3B7PcZzgSwDtK8aYPTpTopWBZO9KwzQ2LGkWnUXu0yeVb8CQPFrku-jpubtXnkPobA9nIEaL_LgzGOooe0XI7PydKR/s1600/ciencia+em+toda+parte...+foto+do+velho.jpg&quot;&gt;&lt;img style=&quot;display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 321px; height: 323px;&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKZR7JmRwmJ-rsAqDnuPKNQZoUBk2N3GPUArBEiOk143SrD8GJpx3B7PcZzgSwDtK8aYPTpTopWBZO9KwzQ2LGkWnUXu0yeVb8CQPFrku-jpubtXnkPobA9nIEaL_LgzGOooe0XI7PydKR/s400/ciencia+em+toda+parte...+foto+do+velho.jpg&quot; alt=&quot;&quot; id=&quot;BLOGGER_PHOTO_ID_5674632204419955474&quot; border=&quot;0&quot; /&gt;&lt;/a&gt;&lt;br /&gt;Pra galera que curte o blog está disponível, também, a  página no facebook.
