Yes, I know that moving charged particles are affected by magnetic fields. But that means that 1 pole of the magnet attracts negative charge and the other one repels it. From that can we derive that one pole of the magnet has + charge and the other one has - charge or not?
When watching some videos about neodymium magnets, I came upon a very interesting phenomenon. Namely, the maker of the video put a large magnet near an old CRT TV.
At first, a big black spot appeared on the screen. This means that the electrons were repelled from from the magnet and didn't...
You can convert fictional currencies in there.
Well... this isn't really a resource, but it can help you when you are figuring out the value of money in your own sci-fi universe.
This is one of the sites. I couldn't find the other ones but I can guarantee you that there are more
Some sources say, that alcubierre warp drive would have no need for exotic matter but to create a warp bubble around a shuttle-sized spaceship would require only 100-500 kg of antimatter. Still some believe it would not function without exotic matter and some positive energy. The question is: Is...
This is more of a Chemistry game but still... powdertoy.co.uk
Powder Toy has fluid and powder physics. If you have ever played Powder Game then this is more advanced. It has nuclear fission, fusion, subatomic particles, electric currents, acids, diferent states of matter, photons and more cool...
I have a site that tells nothing about putting wax between the tubes: http://phys.org/news156781465.html Some say that the wax will make the muscle stronger.
But why is a single nanotube stronger than a bundle of CNTs?
Can we make exoskeletons out of CNTs? I have a few questions
1. Do CNTs expand when electricity is applied or you have to put wax betwen them?
2. Can we produce enough nanotubes to make a full-body suit?
3. Is graphene suitable for an armor? Some say that when you put a elephant on a...
