Why are germans so intelligent and hard working? Is it genetics? What's the deal? Germany is one of the most well-living country in the world despite the wars.

Hey, /sci/. I have a scientific hypothesis about a subject that would normally be discussed in /x/, that is Telekinesis. I have heard countless explanations on how telekinesis would work, mostly involving quantum mechanics and the Heisenberg Uncertainty Principle and some other bullshit. However when I was in high school I came up with an idea for how telekinesis worked that involved one of the four fundamental forces in physics: electromagnetism. It works like this. Try pressing your hand against a table. Notice your hand did not move past the table? This is because the electrons orbiting the atoms that make up your body are producing an electromagnetic field that repels the electromagnetic field generated by the electrons in the atom of that table much like how magnets repel each other when you try to force the identical poles together. That said, these forces are in play when you use your hand to exert force on a solid object like say a cardboard box. So in other words, electromagnetism is necessary in order for an individual to physically affect the world around them. Hell, it's the very thing that is keeping gravity from pulling you through the ground towards the Earth's core. Based on this, my hypothesis is that Telekinesis is simply this same electromagnetic force, except projected over a distance like radio waves (which are also electromagnetic waves). What I want to know is, is there any validity to this hypothesis? Also, inb4 FUCKING MAGNETS

any chance to selfstudy topology somewhere? a solid book or good videos? Ive read through some wiki articles, but I just didn't get my hands on the topic without some proper guidance. thanks in advance

Hey guys, I was bored so I burned sugar. It was cool, first it became caramel brown and then black (only C). but what fascinating was was the fact that when you hold a fire at the gas what comes out from it it burns. what kind of gas is that? (a sugar molecule is C6H12O6)

Hi /sci/ It has been a long time since i did math How do i reverse engineer functions? Ex.: f(-2)=17, t(3)=-8 the function would then look like this: y=-5x+7 Thanks pic unrelated

I do not see the point of science when god is the answer to everything and he decides how everything is. Science is more than pointless the way i look at it.

OK, so the biggest obstacle to marsforming Earth could arguably be its magnetic field. What could we possible do to solve this problem?

>Absolute temperature is usually bound to be positive. Under special conditions, however, negative temperatures—in which high-energy states are more occupied than low-energy states—are also possible. Such states have been demonstrated in localized systems with finite, discrete spectra. Here, we prepared a negative temperature state for motional degrees of freedom. By tailoring the Bose-Hubbard Hamiltonian, we created an attractively interacting ensemble of ultracold bosons at negative temperature that is stable against collapse for arbitrary atom numbers. The quasimomentum distribution develops sharp peaks at the upper band edge, revealing thermal equilibrium and bosonic coherence over several lattice sites. Negative temperatures imply negative pressures and open up new parameter regimes for cold atoms, enabling fundamentally new many-body states. >Negative Absolute Temperature for Motional Degrees of Freedom discuss pic unrelated. my exam timetable

Sci, would you care to explain something to me? This is just what I believe, skip this if you want. When you think something, a manifestation of it is created externally, perhaps in another dimension, it really doesn't matter. Either way, your thought takes form in some way or another. Every living thing puts these off and they are everywhere. This is why you can look at someone and know how they feel. Some people can receive these better than other naturally. So we have shit flying around everywhere out of people and it can be received, to an extent, when around someone. Ever notice the people you are always around you can know what they are thinking? You become adjusted to their frequency and just tap into it much better. If you have a wife, or someone that your close to like that, then have you ever known exactly what that person was thinking, while being miles away? ALL the time I know what friends are thinking, I can finish their sentences. A lot of the time I know where my fiancé is and what she's doing. Sometimes she'll be on her way home and stop somewhere but she wont have told me and I'll drive up there to meet her. It's crazy. That's just my theory though, I'm here to find facts. Why is it, that people can just know exactly what someone they're really close to is thinking or doing even when they are not around them?

if einstein takes 4 minutes do paint 1m2 of wall and newton does it in 3 minutes, how much time do they take to paint 9m2 togheter? assumin newton doesnt stop to drink tea every time he finishes 1m2.
