1. ### Time in different dimension

Is ten minute for an observer in different dimension, with the same speed relatively, same for every observer?
2. ### Wave-Particle Duality

Does this describe wave particle duality correctly? 'Whether observed or not, a matter's wave particle duality still persist. The wave and matter characteristic cannot be isolated: A matter cannot be a wave sometimes and particle the other times. It must be both at anytime. However, when we...
3. ### Quantitized dimension

Recently I was thinking about these statement: 1. Dimension is as if a 3-D graph, which every coordinate is the smallest unit for dimension. 2. Volume of an object is a whole number multiply the volume of the dimension unit. 3. Distance is a whole number multiply the length of the dimension...
4. ### Observation definition

Can someone tell me the definition of observation?
5. ### Wave-Particle Duality

This is my understanding towards wave particle duality: Matter is neither wave or particle.The matter position can only be determined when we observed the matter. When the matter is not observed, the matter can be in any position, and have a wave function. So, I make the following deduction...
6. ### Photon s energy

Photon"s energy When photons trasfer energy to electron, can it transfer only part of its energy and not whole?
7. ### Does the electron teleport ?

Does the electron "teleport"? Let say there's an electron gun in the box as if Schrodinger Cat experiment. The electron is in position A. Since electron behave like wave in this box, the electron can be in any position after the box is close. I don't think that the electron will interact with...
8. ### What is a black hole in 4th dimension looks like?

If there is a black hole in the 4th dimension, how will it looks like in the observer in 3rd dimension?
9. ### What does a researcher do?

What does a : a) Theoratical Scientist b) Experimental Scientist c) Computer Modeling Scientist do?
10. ### Teleportation-possible or not?

Let say our dimension is a 4Dimension graph, and every position is a coordinate. If a matter disappear in its original coordinate and reappear in another coordinate(without travelling), does this contradic with any physic laws or theories? In other word, are there any physics facts that show...
11. ### Can Dimension and Time be quantized?

Can Dimension and Time be quantized? For example, distance and time is a whole number multiple a smallest unit. p/s: I don't have any facts to support my question, so this is possibly one of my illogical thought :smile:
12. ### Where is the electron?

To make myself clearer, lets imagine the same apparatus used by the Schrodinger Cat Paradox(without the cat and the poison). An electron is shot from position A. It is moving to the other side of the box. Now, the quesion is, when we open the box and observe the electron after a long period...
13. ### Photon and its momentum

Momentum can be categorised under electromagnet force, and electromagnetic force carrier is photon. But photon have momentum. Isn't this paradoxical?
14. ### What is in the strange point?

When universe is still a strange point, what is in the universe? (asume big bang did happen and universe was created in a certain time)
15. ### Alternative way to replace CFC?

Since CFC is hazardous to our atmosphere, are there any better substitute to replaced CFC in fridge, air conditioner etc.?
16. ### Beta decay of a neutron

When an atom experience beta decay, will the atom become ion? This is my deduction: 1.An atom will release an electron in beta decay. 2.The electron is replaced by the electon produced from the decay of neutron. 3.However, the proton number increase by one. It still need one more electron...
17. ### Why light diffract?

Why waves, such as light, will diffract when they pass through a small hole or slid?
18. ### Potential of a charged plate

Quote: “We can see from our definition that the positive plate in Fig. 23-1 is at a higher potential than the negative plate........." I saw this statement in a book. May I know how to calculate the potential of a charged plate?
19. ### Photon's role

Photon doesn't interact with external force and move with light speed. But why can it act as force carrier, play a role in photoelectric etc.?
20. ### What exactly is electric field?

Recently I am reading about electirc and electromagnet. I found electric field and the field line a bit confusing. What forms the field, or the field line? Is it photon? Secondly, why must electron orbit around proton, and not proton orbit the electron? :confused: Thanks in avanced.
21. ### Does science career suit me?

I like science(at least I think so), but I don't like every part of it equally. For example, I like Relativity and QM, but I don't really like mechanic. I like to ask question and do experiment, but I wonder whether I suit the research career, or which science field. Are there any test or guide...
22. ### Evolution Factor

Beside mutation, molecular drive, and variation of genetic, what are the factors which triggled the evolution?
23. ### Website for self-learning purpose needed

Your guys physic knowledge is so awesome! I am a secondary student, and I wish to learn more about physic. Can anyone suggest a website to me?
24. ### Does light wave never collaspe?

1. Observation means interaction in QM. 2. Photon doesn't interact with gravity or electromagnetic force. 3. Thus, light wave is never observed and will therefore maintain superposition. Is this deduction correct?
25. ### Why photon never stop?

I know photon has no mass, and have energy 0/0, which mean photon can have any energy. But photon can interact with matter. It also can be absorbed by electron. But these interaction, and the fraction never stop photon, nor do photon lose it energy. Why?
26. ### How do we control our thinking?

For example, when you are doing an essay, you must get some idea to write. Thus you send an impulse through the nerve cell to the brain. But what send the impulse, and how is it controlled?
27. ### Why light go straight?

In normal condition, light always go straight. But since photon move randomly, why must they go straight?
28. ### Communication among animals

As we all know, animal can communicate with each other with body language, sounds, etc. just like human. But does every animal of the same species communicate the same way? For example, are cats in different areas communicate the same way?
29. ### What make system different from environment?

When I was reading about QM, I always saw the word system and environment. What differentiate them?
30. ### When do livings acquire the ability to think?

If I am not wrong, the most primitive life is in molecular form. Somehow, they acquire the ability to duplicate themselves, and get better and better through evolution. But, how, and when do livings acquire the ability to think?(In other words, acquire a brain)
