There is really no better way to be judged than an internet journal. I'm not gonna lie, that doesn't make me want to burn myself on any6 unnecessary stakes, but who knows who or what is watching now or ever. And don't get me wrong either, I'm not saying that means I reject whatever deity may be at the top of the spiritual food chain, but I do believe in madness. As well as equality. And equality for madness. Regardless, (retardless?) I do find myself with more than one thing on my mind throughout any given day, and in no special way, I plan to spoonfeed that to you, the general populace. Another words, if your here, and your reading this, you must really enjoy suffering.

a friend asked me a way to have a bigger lunchbox.
this is what i told him.

and onto some science. I found this in a book fer college a couple weeks ago, and thuoght i'd share. If your up to the task, it might just be more everyday for you than you think.

Thomson’s experiments
Physicist J.J. Thomson at Cambridge carried out a series of
de nitive experiments on cathode rays around the year 1897. By
turning them slightly o course with electrical forces, k, he showed
that they were indeed electrically charged, which was strong evidence
that they were material. Not only that, but he proved that
they had mass, and measured the ratio of their mass to their charge,
m=q. Since their mass was not zero, he concluded that they were
a form of matter, and presumably made up of a stream of microscopic,
negatively charged particles. When Millikan published his
results fourteen years later, it was reasonable to assume that the
charge of one such particle equaled minus one fundamental charge,
q = ��e, and from the combination of Thomson's and Millikan's results
one could therefore determine the mass of a single cathode ray
particle. The basic technique for determining m=q was simply to measure
the angle through which the charged plates bent the beam. The
electric force acting on a cathode ray particle while it was between
the plates would be proportional to its charge,
Felec = (known constant) q .
Application of Newton's second law, a = F=m, would allow m=q
to be determined:
m
q
=
known constant
a
There was just one catch. Thomson needed to know the cathode
ray particles' velocity in order to gure out their acceleration. At
that point, however, nobody had even an educated guess as to the
speed of the cathode rays produced in a given vacuum tube. The
beam appeared to leap across the vacuum tube practically instantaneously,
so it was no simple matter of timing it with a stopwatch!
Thomson's clever solution was to observe the e ect of both electric
and magnetic forces on the beam. The magnetic force exerted
by a particular magnet would depend on both the cathode ray's
charge and its speed:
Fmag = (known constant #2) qv
Thomson played with the electric and magnetic forces until either
one would produce an equal e ect on the beam, allowing him
to solve for the speed,
v =
(known constant)
(known constant #2)
.
Knowing the speed (which was on the order of 10% of the speed
of light for his setup), he was able to nd the acceleration and thus
the mass-to-charge ratio m=q. Thomson's techniques were relatively
crude (or perhaps more charitably we could say that they stretched
the state of the art of the time), so with various methods he came up with m=q values that ranged over about a factor of two, even
for cathode rays extracted from a cathode made of a single material.
The best modern value is m=q = 5.69 10��12 kg/C, which is
consistent with the low end of Thomson's range.
The cathode ray as a subatomic particle: the electron
What was signi cant about Thomson's experiment was not the
actual numerical value of m=q, however, so much as the fact that,
combined with Millikan's value of the fundamental charge, it gave
a mass for the cathode ray particles that was thousands of times
smaller than the mass of even the lightest atoms. Even without
Millikan's results, which were 14 years in the future, Thomson recognized
that the cathode rays' m=q was thousands of times smaller
than the m=q ratios that had been measured for electrically charged
atoms in chemical solutions. He correctly interpreted this as evidence
that the cathode rays were smaller building blocks|he called
them electrons | out of which atoms themselves were formed. This
was an extremely radical claim, coming at a time when atoms had
not yet been proven to exist! Even those who used the word \atom"
often considered them no more than mathematical abstractions, not
literal objects. The idea of searching for structure inside of \unsplittable"
atoms was seen by some as lunacy, but within ten years
Thomson's ideas had been amply veri ed by many more detailed
experiments.
