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've been watching some science related videos lately and wanted to know what are some of your favorite videos and channels on youtube. My favorite channel so far is Sixty Symbols. And favorite video https://www.youtube.com/watch?v=UBmBMmuUBMk

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

Photographic memory

Are there some downsides in people with eidetic memory? Not something like they're autistical, but something else that might affect their intelligence more commonly than "normal" people. I find it quite interesting how someone can remember a lot of things, almost feels like cheating when considering that this kind of memory can be used for incredible stuff that might require excellent memory. Does anyone on /sci/ have photographic memory? Does your friend have photographic memory? Also just general talking about the subject

Can someone help me visualize whey a negative times a negative ='s a positive my initial response to doing this on a number line would be to go to the negative number and proceed to go in the negative direction with the other negative number

Would it be possible to make a blimp that contained vacuum rather than Helium or Hydrogen? What material would be necessary, and could this ever become practical as the Earth slowly loses its Helium?

Hello /sci, I need your help on something. I'm trying to use wolframalpha to solve a 6 variable equation. It doenst seem to work. Does anyone know a good site to do this on ? Thank you so much ! PS : Here it is 1797*a+899*b+2696*g=0 ; 1797*b+899*a+2696*g=3 ; 1652*b+826*c+583*f=-3 ; 1652*c+826*b+583*f=147580 ; 1652*d+826*b-583*f=147580 ; 1652*c+826*d-583*f=295163 PS2 : Me and my friend are working on the displacement field of a beam.

if prime numbers can be easily guessed with stuff like the ulam spiral, why do people still think RSA is secure?

Have you ever had to study anything so obvious that you could have easily figured out by your own in a matter of minutes or seconds? I have three: Bolzano's theorem. Rolle's theorem. Mean value theorem. I am baffled at how stunningly easy these theorems are and yet Bolzano and Rolle immediately get their names stamped in History for it. Not that they weren't great in mathematics but still... Anyone ever felt similar?

I've been thinking about the Chinese Room experiment for a while, and there is something that sprung to mind, it's probably wrong, but I wanted to know what /sci/ thinks. Atoms and molecules act in the same way as the man inside the room does, they receive stimuli, and due to the laws of physics, an effect occurs. We are conscious beings, but our building blocks are not, meaning that the man inside the room might not be "conscious", but enough of them compounded with each other could produce something that is. Does this make any sense?

Science of Dragonball How the Kaio Ken works The energy is drawn from the Dan Tian (energy field in the lower body, Chinese: ??), and sent out to the chest, back, head and four limbs. The Ki travels underneath the skin and causes the muscles to bulge and the flesh to become thick around the bones. As the Ki reaches the surface of the body in this dimension it manifests as heat, wind, and electricity. When Goku employs the Kaio Ken he opens up all the cells in his body and taps into their energy on a molecular and sub-molecular level. Goku’s cells, molecules, atoms, neutrons, quarks and all other sub atomic particles are opened up and tapped into for a very short amount of time.
