It's hard to compare the swedish math education to the american. I don't know how much calculus I know for instance compared to what year of college/ high school in US. But derivatives, integrals, differential equation, complex numbers (don't know if what i read qualifies as complex analysis)...

Hi! This is a question for the physicists. What types of math do I need to study the physics of ... let's say loop quantum gravity, string theory, quantum electro dynamics/ chromodynamics and general relativity on the basic level? Tnx

Thanx!

Hi, I was just wondering if there is available the proof of fermats last theorem on the web, as well as the proof for the poincare conjecture. I was looking over the Riemann hypothesis and I'm having some difficulties... It's claimed that the functions have trivial zeroes at the even...

Damn! I was going to intergral from 0 to 2r... Trial and error

Hi, i can't seem to get the antiderivative to the formula f(x)=(2xr-x²)^(1/2) right. Can anyone help me out? By the by, if could anyone link a site with formulas for antiderivatives that would be nice.

It's quite interesting that some of the depression medication has proven to be a big fat placebo, i.e. SSRI-medication. The effect has been the same with SSRI as placebo pills in patent diagnosed with depression, exept in cases where the depression was extremely severe. This argument kind of...

Care to link that?

In that case, thanks :cool:

I understood your point. There's so very little we know about our brains. It's the least understood object in the universe :cool: One of the greatest questions in science is right with what gravity is and how the perfect guitar riff must sound like what the scientific definition of...

Don't get too excited, this theory isn't perfect either, but it has a lot of potential ;D

Circadian rhythm = any rythmic behaviour with periodic time of 24 hours

Aren't there examples of plants/animals whos circadian cycle is not stimulated but dictated by external stimuli?

Here's an interesting article on the topic: http://www.scienceblog.com/cms/physicists-challenge-notion-of-electric-nerve-impulses-say-sound-more-likely-12738.html It suggests that nerve-impulses are mediated not by electrical signals, but by soundwaves, rendering the electrical signals...

How comes the clinical presentation differs between LE and MG? In both cases anti-bodys attack the neuromuscular junction, LE attacks the calcium channels on the pre-synaptic axon terminal, and MG the receptor muscles Na/K-channels... Why is there difference in symptoms?
