Cheers Pythagorean. I was thinking of interviewing a guy working on quantum gravity first. However, I know somebody in HEP who I'm sure would be keen as well.

Hi Guys, I am starting a new blog and was looking for a bit of input. As I have friends in many "interesting" research groups around the UK, I was thinking of doing a bit of science journalism, interviewing people about their research. I was looking for input/advice, specifically if there...

Most definitely weak!

Could somebody please explain to me the difference between flavour and mass eigenstates. The question is "Neutrinos can be produced from charged pion decay, What force is involved, and at the time of creation is the neutrino in a flavour or mass eigenstate, and why?" And why would it be...

Wave function collapse is a highly debated area, and to my knowledge there is no clear cut answer. My question for a while has been why is only when we "observe it" does it collapse. Everything in the universe is one big system as everything interacts by gravity etc, and so there is never an...

I think a more interesting way to bring quantum physics to a larger scale would be to try and use viruses in a double slit experiment. This would show that life can exhibit wave properties, assuming one thinks viruses are actually alive.

The strength of an object does not scale with its size...so yes, there would probably be a difference. You would not be able to walk without a lot of your bones breaking.

HAHAHA...i done some of those questions last year for revision! lol

Listen to blechman, if you do have fifteen minutes at maximum your going to have about 30 seconds a slide, do you think you can explain the De Broglie hypothesis in that time or quantum tunneling in a minute. My advice is keep it simple and keep the audiences attention, there is no point...

Thanks for pointing that out for me, I was under the impression that they were 2 sides of a coin.

At the moment i am studying a level physics and so i do not understand all what these contributers are talking about, but i am eager to learn and i will now read up on it. What I was originally talking about was the original Newtonian view of gravity ie. the inverse square law etc. Thanks I...

The first article of the most recent new scientist talks about this...check it out.

Is it not weight that causes something to accelerate towards a mass, weight being caused by gravity. w=mg

I had to do a similar thing in my physics class only i had to talk about bucky balls for 5 minutes. I just talked about carbon nano tubes and put a large spinning picture up of one and the teacher was impressed. The secret is to distract them with nice pictures and make up the rest, no one will...

Sorry, what i meant was there are a few similarities between them and if this could be one. I have read about gravtomagnetism in the new scientist about a year ago...i must dig it up out of the pile of them under my bed. Thanks
