1. ## Does it make sense to say that something is almost infinite? If yes, then why?

Thanks for guidance. ðŸ™‚
2. ## Does it make sense to say that something is almost infinite? If yes, then why?

So can I say ''infinite pieces'' of vertical lines instead of ''almost infinite pieces''?

4. ## Does it make sense to say that something is almost infinite? If yes, then why?

I remember hearing someone say "almost infinite" in this video. As someone who hasn't studied very much math, "almost infinite" sounds like nonsense. Either something ends or it doesn't, there really isn't a spectrum of unending-ness. In this video he says that ''almost infinite'' pieces of verticle lines are placed along X length. Why not infinit?
5. ## Why do shapes with the same area have different perimeter?

what do you mean by considerable (infinite) variation?
6. ## Why do shapes with the same area have different perimeter?

For example, Consider two shapes; a circle and rectangle. Both these shapes have same area but the perimeter of circle is less than that of rectangle. Why?
7. ## Can quantum particles communicate in the past?

The quantum entanglement and delayed choice quantum eraser variation to the double slit experiment has given very strange results. So if a particle is detected then the pattern is changed. Does the detected particle communicate with its entangled pair in the past? or there is another explanation to it?
8. ## Do photons have mass?

Fermions are weird in that they distinguish left and right also. What do you mean by that?
9. ## Do photons have mass?

Therefore I can say that, ''Quantum Particles are weird. They only work in one way, 'their way'.
10. ## Do photons have mass?

So each quantum particle has a unique set of characteristics?
11. ## Do photons have mass?

Does the same happen for electron?
12. ## Do photons have mass?

How do we know that?
13. ## Do photons have mass?

So photon only works one way, 'Its way'.
14. ## Do photons have mass?

Doesn't momentum depend on velocity and mass?
15. ## Do photons have mass?

Do photons have mass?
16. ## Are we waves ?

Quantum particles are not little spherical balls. They are just localized waves. At all times, their behaviour is described by a wave function. If quantum particles are sent through double slit, we obtain an interference pattern which tells that they are waves. If the particles are sent through single slit, a non interference pattern is obtained. But the non interference pattern does not tell the opposite of what interference pattern tells. The non interference pattern does not mean particle. It just means we are inconclusive about waviness. So quantum particles are waves but their tininess can give them some semblance of location. In general double slit experiment is not a wave test or particle test. Its a 'which way' test. The point is to test which way something went. For example, did a photon went through slit A, slit B or both slits simultaneously.
17. ## Are we waves ?

OK. what is the difference between particle and wave?
18. ## Are we waves ?

So you mean they have mass?
19. ## Are we waves ?

Give an example that quantum particles behave in ways that waves definitely do not. Quantum particles always behave in the way waves do
20. ## Are we waves ?

Quantum particles are waves. We are made up of them. So does that makes us waves? Sorry for such a stupid childish question.

23. ## How is an atom ionized by electron impact?

Can someone walk me through in detail what happens when an atom is ionized by colliding with an electron? I would prefer a solid example so I can understand it more concretely. What I think: The electron collides with the atom giving it energy, but then goes away after that. This energy excites an electron inside the atom, which receives enough energy to leave the atom. The atom is ionized. However, I also thought of another way: The electron collides with the atom and gets bound up in the atom. The atom is now ionized (negative ion, since extra electron) Are any of these descriptions correct?
24. ## Ionization Energy

Why ionization energy of Nitrogen is more than that of oxygen?
