Hi guys, I have recently come across a video on YouTube which gives you a brief intro to Quantum Mechanics/Physics. Can someone tell me if this video is accurate? Could someone suggest some introductory reading or resources for learning QM? Is it even accessible to a 15 year old? Should I just...

Thank you very much for your help it has certainly made a difference thanks again for everyone's contributions. :)

Hi guys, essentially I have been talking with my Physics teacher about Beta Decay and she was saying that sometimes electrons come from the nucleus because of the quarks in the protons and the neutrons? I didn't fully understand it so I have likely got it wrong what she was trying to explain. Do...

Thanks for your speedy replys guys. I am only a high school student so I don't exactly have contacts in the physics world. I will try your suggestions, thanks again for your time. :)

Hey guys basically as the title says, I have been recently trying to find these papers but I have had no luck. All I seem to get is articles from Magazines like New Scientist and Scientific American. Any help would be greatly appreciated. Thanks in advance MattA147. :)

Transisiton metal electronic structure question. :) Hey guys, basically I know that Chromium and Copper "donate" one of their electrons from the 4s sub-shell to the 3d sub-shell. Is this true for ALL transition metals? Any help would be greatly appreciated. :)

Thanks for your reply, that article is making a lot more sense than any other article I found. It is appreciated. :)

Electronic Structure question? :) Hey guys essentially in my GCSE Chem class we were told that the maximum number of electrons that can be held in the first four shells are as follows - 2,8,8,2. Now in my AS Level textbook it is saying that it goes 2,8,18,32. Can someone please explain to me...

It is to do with ionization energies. When you go from left to right (and up) you encounter smaller atoms. Which means that the proximity of their electrons is a lot closer than a larger atom. Due to the fact that the Oxygen electrons are a lot closer to the nucleus of the atom a higher amount...

Hi guys basically I'm in secondary school and my teacher started taling to me about the four forces in space which are tryin to be unified by TOE and the Grand unification theory. She said that at my level I don't need to know what they are and she said that she wouldn't go into them in depth...

Hey guys, in class today we learned about the life cycle of a star and at the very first stage gravity pulls the helium or Hydrogen nuclei at such a speed that they fuse (nuclear fusion). As I understand it there is little gravity in space so where is this extra gravity coming from? Thanks...

How in a series circuit do the components know how much of the "electricity" to use? How does this happen? Why doesn't the first lamp in a series use all the volts? How does it know if there are any other lamps in the circuit? Any help would be greatly appreciated. :)

How do I work out "a" as in F= ma? Hey guys basically just as the title says. Any help would be greatly appreciated. :)

What is the national Grid? Where does it run? How does it work? What is a transformer? 3 Advantages of the national grid 3 disadvantages of the national grid Any help would be a great help. :D
