Response to EPSRC Research Portfolio Map

2011-07-26T18:04:00.000+01:00

21 July 2011

In response to the publication today, Wednesday 20 July, of the Engineering and Physical Sciences Research Council’s (EPSRC) map of its full research portfolio, Professor Sir Peter Knight, the Institute of Physics’ incoming-president, said, “Members of the physics community have already expressed their concern that the UK’s strong track record in science, which has stemmed from funding excellence in research, as judged by scientific peers, will be jeopardised by too strong a focus on short-term gains.

“They also have concerns about the introduction of a fundamentally new approach without broadly-based consultation across the science community. Although the Institute of Physics was briefed on the plans, despite statements to the contrary, the Institute was not consulted.
“A key part of EPSRC’s remit is to fund basic research and enable researchers to take the first steps in, what might promise to be, exciting new fields. This type of research can lead on to key new scientific and engineering developments with large societal benefits and huge economic value.
“A prime example is the discovery of superconductivity 100 years ago; a discovery which lacked any obvious applications for 50 years but has since made magnetic resonance imaging (MRI) possible, saving millions of lives and creating a flourishing global industry. MRI is just one example that illustrates how scientific advances come about.”

Pinpointing Problems In The Brain

2011-07-14T16:09:00.000+01:00

Neurologists Use New Brain Scanning Device To Better Control Seizures

March 1, 2007 — Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much more accurately than the traditional method of electroencephalography (EEG). Using a combination of MEG and MRI, neurosurgeons have a detailed brain map that allows them to remove just the damaged tissue while preserving healthy cells.

ScienceDaily (July 12, 2011) — Machine logic is based on human logic. But although a computer processor can be dissembled and dissected in logical steps, the same is not true for the way our brains process information, says Mark Shein of Tel Aviv University's School of Electrical Engineering.

First raytracing tutorial

2011-07-03T16:37:00.000+01:00

If you read just the FIRST page from this webpage, it goes into a lot of details of how raytracing works. It also has pictures. We won't be using his code as our first tutorial, it's pretty complicated for beginners. So don't download the code.

http://www.flipcode.com/archives/Raytracing_Topics_Techniques-Part_1_Introduction.shtml

So let's take a look at the code we will be trying. It's really small and thus makes a good starting point. It simply draws a sphere and has ambient light.

They are using OpenGL for the tutorial. I am using SDL. So I am converting it to use SDL without hardware acceleration. If we need higher frame rates I will change it from software rendering to hardware rendering using OpenGL, which will run under Linux and Windows.

links to the code. One file is for doing the graphics, the other for doing the raytracing.

Being fooled by optical illusions might mean you’re more self-aware

2011-07-03T16:26:00.000+01:00

But bigger is not necessarily better in terms of brain power. It might be better to have fewer synaptic connections for more focused and coherent decision making. A brain with more visual volume and less frontal volume might actually work better."

Not everyone reacts to optical illusions equally: some are completely fooled by them, while others just can't see what all the fuss is about. It depends on the size of your visual cortex...and that can determine how introspective you are. Specifically, the amount of gray matter in the visual cortex goes a long way to determining how much a person is able to process and solve optical illusions, a fact that was discovered last year by researchers at University College London. They then decided to take things a step further by looking for other parts of the brain that correlate with the size of the visual cortex.
