Seeing as how the LHC produces two beams in opposite directions with energy 7 Tev each (total collision energy is 14 Tev) this accelerator has 3 or 4 orders of magnitude to scale before it can even begin to compete with the LHC.
I first learned of the neutrino oscillation through a profs class notes. Since I respect the guy too much to actually put up his PDF (it was an example in the application of matrix diagonalisation) the best I can do is give the reference he used at the end. It looks like it has alot of detail (51 pages) but apparently it is suitable for an introductory quantum course (I haven't read it so I cannot attest).
As someone who is a physics undergrad... I don't know, maybe they don't sleep. Or don't hand in assignments. I am not willing to do either so I had better get back to my PDE's assignment.
As other people have said, perfect on every assignment won't help you in the midterm and the final. I am a physics major and I have seen the same sort of stuff, students will download the assignment solutions for next years classes and hope they are the same (often they are), or order the solutions manual from the publisher (alot of them are suprisingly lax in who they send it to).
Personally I find that sort of pointless, sure it means I can get 100% on the assignments, but when the exam is worth 55% of the mark and the midterm is worth 20%, that doesn't amount to much. I generally learn the course by struggling through the assignments, no matter how little they are worth. When it comes time for the final I have significantly less studying to do.
Gauss's Law
Green's/Stokes Theorem
Eulers formula (Of Course)
The Wave Equation (And Schrodingers Equation)
Gauss's Law is one of the coolest equations I have ever used, unfortunatly it is pretty useless in all but the simplest of circumstances.
Fermions are anything with spin (2n+1)/2, whereas bosons are anything with integer spin n. In both cases n is an integer.
Atoms can also be fermions if the electron configuration dictates it (electrons are fermions but the electron configuration may cancel out and make the net atom into a boson), For example helium atoms are bosons but silver atoms are fermions. In fact, the original Stern Gerlach (did I spell that right?) experiment was done with silver atoms.
About a year ago I saw a presentation where some people in Spain I believe were using BEC to slow light down. They had some pictures of a monoatom which were black dots. I barely remember the presentation though.
Perhaps I should clarify, I didn't want to give my SIN to VISA despite the fact that it took 3 weeks longer because I didn't trust VISA with my SIN
Since then my SIN was stolen from the offices of the pension managers for a business I used to work at, so I put a flag on my credit file. This requires VISA/The Bank to demand a photo ID and I believe a birth certificate from whoever is applying for credit in my name.
IIRC the only reason VISA wanted my SIN was to do a quicker credit check.
That's right, the last time I had to use my SIN was for my taxes last April, the time before that was when I was filling out the staff information form for my current job.
As I mentioned in my post I had mine stolen, this prompted me to put a flag on my account so that no one could apply for credit in my name. This means that whenever anyone applies for credit in my name they have to go to the bank and prove that they are me, with photo id and a birth certificate IIRC
I originally applied for my credit card through my bank and I think they compared my signature to the one they had on file, and made sure I had my access card with me.
In Canada the equivalent of the SSN is the SIN (Social Insurance Number). In any case a few years ago it became law that you cannot be refused a service because you refuse to give out your SIN. The exception to this is that it has a valid use (Pretty well the only valid uses are ones that deal directly with taxation, for example you must give it to your employer so they can report income tax stuff correctly).
That being said companies can ask you for your SIN but you are not obligated to give it to them. For me that meant waiting 3 weeks longer for a credit card, but at least VISA doesn't have my SIN
The main reason why I am so paranoid about my SIN is I actually had mine stolen a while back. A company I used to work for outsourced their pension stuff. About a year ago the place got broken into and computers containing my SIN along with 30000 or so other people got stolen. The process of making sure that no one can apply for credit in my name is something I do not want to repeat.
I find it sort of funny when someone tries to take notes on a laptop in classes I am in. First of all I should explain that I am a physics major at a university with a tiny physics department (6 undergrad honours students are in the same year as I).
In any case I had a second year class called modern physics. It is basically a relativity and introductory QM survey course which alot of majors require their students to take (this means it has about 40 people in it). In any case, on the first day one guy walks in with a laptop and starts setting up. When the prof walked in he took one look at the guy with the laptop and started laughing because he knew that it would be impossible to take notes on a laptop.
Lo and behold the laptop geek dropped the class after he failed the first midterm miserably. His notes were likely terrible
That being said, I think that the only place a laptop could be usefull is well out of the sciences (except perhaps computer science, although I would stick with a pencil and paper)
Interestingly enough, a physicist by the name of Robert Forward (did alot of work with space tethers) published a book called Dragons Egg about life on a neutron star. He actually said it was really a book on neutron star physics described as a science fiction book. Anyways the sequel to it was called Starquake where exactly this happened. Both books were interesting reads, and although this is kind of off topic, it just reminded me of them.
I can see it now, in the year 2505 a United Planets resolution will propose that because computer programs weren't built to handle a 25 hour day, we should make a leap day once every 12000 years
I doubt it is Al Qaeda, since it was obviously timed to coincide with the G8 summit it was probably extreme anti-globalisation people or something along those lines
"The BBC has an article that pretty much sums up everything you might need to know if you wanted to refine nuclear fuel and build some atomic weapons."
This is true, in the same way
"Everything you need to know how to build a car is that pistons get pushed down by gas exploding which turns the crankshaft which turns the wheels"
is everything you need to know to build a car. Or
"Think of space as a sheet with masses as balls"
Is everything you need to know about general relativity
A general overview of anything is usually quite simple however in practise building a nuclear bomb is pretty difficult.
I am a huge fan of rhythmbox. I prefer it to iTunes any day. I use rhythmbox at home however at work I have to use iTunes (I take my ipod back and forth and plug it in at work). iTunes is alot slower, and has useless eye candy (so many animations... so useless)
My teacher did this, he used a cattle prod but it is the same thing.
The funny part was that he got stuck, he wasn't sure he could turn the thing off without grounding himself. Since he was holding the end of the cattle prod in one hand, and the tube in the other hand he really didn't have any free hands. He solved it by getting another teacher to come and help him.
They are missing the blueshift you would encounter at that speed. However I guess they couldn't be accurate because wouldn't the frequency would shift to far above the ultraviolet quite quickly?
I was wondering what the original post and this one was talking about until I realised that I am in canada and am automatically redirected to the google.ca page. groups.google.ca still has the old interface
Great now you have me worried about my health! (That is about my height and weight). Although I fell fine and am active and stuff, just quite skinny. Some people are just naturally skinny, I eat quite a bit, never skip any meals and never gain a pound. Although I have been like this all my life.
Technological tends to be an exponential thing. We have only had high school mathematics (calculus) for the last.3% of that time. We have only had a decent understanding of electricity and magnatism for the last.1% of that time (Maxwells equations). In the past 400 years (I would say that the invention of calculus is the beginning of this) the human race has come a long way much farther than from then to the dawn of recorded history.

Man, why not print out certificates for "The People Fund - Money for People", it would suck slightly less.

Whoops, when I say helium I mean helium 4 which makes up the unbelievably vast majority of helium
