Yeah a graph could help! by figure, I mean graph

Yes. How is it at rest if a force is acting on it?

When a ball is thrown upward it becomes at rest at maximum height, at this it is not in equilibrium although it is at rest. It is not at equilibrium because force of gravity is acting on it? Still I cannot find good explanation from exam point of view.I also cannot find the figure/diagram.

Can you suggest a video or an article on dimensions(geometry) ?

Thanks for guidance. 🙂

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

1:23

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?

what do you mean by considerable (infinite) variation?

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?

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?

Fermions are weird in that they distinguish left and right also. What do you mean by that?

Therefore I can say that, ''Quantum Particles are weird. They only work in one way, 'their way'.

So each quantum particle has a unique set of characteristics?

Does the same happen for electron?

How do we know that?

So photon only works one way, 'Its way'.

Doesn't momentum depend on velocity and mass?

Do photons have mass?

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.

OK. what is the difference between particle and wave?

So you mean they have mass?

Give an example that quantum particles behave in ways that waves definitely do not. Quantum particles always behave in the way waves do

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

Yes. Please explain it more.
