ETH Zürich physics student reporting in, bretty good, workload is intense, but the second and third year of the bachelor are rumored to be less stressfull. The ETH is among the best universities of the world when it comes to physics. (still wishing I was studying in Cambridge though, oh well). Any questions?
>>7698667 >Girls do better than boys in math + science That is definitely not true. I will give them that girls and boys can be as good as each other when it comes to math and science. Seriously, this femenist proapaganda of "womyn be gud and buys b dumm" hurts my head.
>stereotypes keep them away from STEM Says who? Where's the data. Has a woman ever said: Oh, I really wanted to get a 300k starting job in mathematics but the stereotypes... Comment too long. Click here to view the full text.
>>7698667 Arguable, the success you experience in school and the success you gain in professional work is not likely as correlated as you would like. The 1%'ers that make it as successful and productive STEM'ers, especially in the hard sciences, are different in a way grades only partially show. They certainly got good grades, but there is a huge difference between learning and creating.
ITT I will try to solve (and in fact solve) all the Millennium Prize Problems one by one. I will do so by a new proof technique that has been proved to be quite powerful. It combined homothopy theory with algebraic geometry. Having said that, the proof technique itself is elementary though. So, let's go ahead.
1. [math] \displaystyle P = NP [/math]
By definition, polynomila algorithms admit decomposition in chains of smaller polynomial algorithms. Consequently, polynomial time algorithms do not solve problems where blocks, whoose order is the same as the underlying problem, require simultaneous resolution. Thus, in fact [math] \displaystyle P \neq NP [/math]
2. Hodge conjecture
Assuming that if a compact Kähler mainfold is complex-analytically rigid, the area-minimizing subvarieties approach complex analytic subvarieties. The set of singularities of an area-minimizng flux is zero in measure. The rest it left to the reader as an easy routine excersize.
3. Riemann hypothesis
This is a simple experimental fact. [math] \displaystyle 10^13 [/math] roots of the Riemann hypothesis have been already tested and it suffices for all practical applications. In fact, one state a suitable statistical hypothesis and check it on the sample of, say, [math] \displaystyle 10^5 [/math] roots.
4. Yang–Mills existence and mass gap
Well, discrete infinite bosonic energy-mass spectrum of gauge bosons under Gelfand nuclear triples admits non-perturbative quantization of Yang-Mills fields whence the gauge-invariant quantum spectrum is bounded below. A particular consequence is the existence of the mass gap.
>>7698139 Ejaculation decreases testosterone (and dopamine), while increasing prolactin. Lack of orgasm increases testosterone levels for ~1 week. I don't know if it truly drops back to baseline after that, but that's what's frequently said. No literature I've read has gone into that aspect.
Is theoretical physics basically a meme science now?

First year student here. Not 100% sure on major but thinking about Chemistry. What to expect out of Gen Chem. 1 and Calc 1? Also, I have to take either philosophy or psychology and I'm going philosophy, anyone have any opinions on Philosophy classes?
>>7697650 Elevation of heat shock proteins (by non-thermal means). Certain cells are vulnerable to its magnetic field, and more so during specific parts of their cycle. Exposure results in increased ROS production. Changes in gene expression, naturally, are also observed.
Not going to go into the research about pyramidal cell dysfunction, or dysfunction of cells in the dentate gyrus / hippocampus. Don't care to go into increased blood brain barrier permeability either. Some studies show statistically significant... Comment too long. Click here to view the full text.
