According to modern definitions, the unqualified word "mass" refers to invariant mass (which for massive particles is called "rest mass", although that term makes no sense for photons which can never be at rest). Thus, photons are referred to as massless particles.

The kind of mass you're talking about is nowadays referred to variously as "mass-energy", "effective mass", "relativistic mass", or just "energy" when people feel like slurring the difference.

Really? Where did you study?

UMIST cosmology course

Google search on term "rest mass" at UMIST, in the UK

Similar google search on Stanford in the US

You can run the same search on Berkeley, Princeton... you name it. You'll get very very similar results.

So either no-one's using the modern definitions, or you're talking about a very specific subfield where they've defined their own terminology.

It's real. I applied to study it at Southampton University as a fall-back in case I didn't get in doing Software Engineering at UMIST.

Nonsense. Apparently you missed all the other quotes on this thread, or didn't believe them. Just in case it'll help, here is the math. Note that Jupiter is not even close to half of the mass required for sustained fusion.

Here is a 700+ page book similar in content to a freshman college text MotionMountain

This is a Classical Electrodynamic book at a graduate level Classical Electrodynamics-Bo Thide

A site for Statistical and Thermal Physics with some good notes by Harvey Gould Statistical and Thermal Physics (STP) Curriculum Development Project

Quantum Mechanics--Niels Walet-- see the "Big .ps file

A list of books to look into Cease's Book List

A few authors I like are A.P. French, Halliday Resnick for intro, Griffiths

A very respectable Oxford Physics booklist can be found in their handbook here

Hmm, for some reason, /. tells me "This discussion has been archived" when I try and reply in your journal.

Anway, try talking to these people. Nice folks. If they don't have anything that could help, I'm pretty sure that they will be able to point you in the right direction.

Has anyone else gone to college intending to prepare for one career, only to fall into another, either by luck or design?

Many people ended up programming based on these forces. When there is a scarcity, employers tend not to care much about your degree (the recent dot-boom was an extreme example of this phenomena). But inversely, the number of jobs for physics majors per se has always been far less than the number of people competing for them.

Mathematically, it's the Pigeonhole Principle. Small numbers of jobs and large numbers of people chasing them lead to many people not getting the jobs. So they go elsewhere by necessity. It's that simple. See what a math education gets you ...

> > I suppose it is also true if there are 367 people in the room, there is a 100% chance two of them share the same birthday.

> no, there is always a finite chance that someone would have a unique birthday

No. There are only 366 possible birthdays (365 most years). If everyone in the room has a unique birthday, there can not be more than 366 people there.

This is a pretty simple idea, but it actually has a name - The Pigeonhole Principle.

Students would be able to view previous examinations, learn exactly what questions professors ask, and learn only those questions. This will lead to focused studying instead of the broad studying necessary for a real education.

You mean you were never given past papers at University? Wow. You must have some really unimaginiative and lazy professors and lecturers. I studied at UMIST Computation and all past papers for all courses including a large amount of the notes were freely available internally, both in paper and Word .doc format. No problems there because the papers were so different every time.

Professors will have extra work to do in keeping the web page up-to-date.

Ummm... what do you think they write their lecture notes and exam papers on? A typewriter? No, all this means is that Word and Powerpoint files just have to be linked to on a departmental web-site. If they want to convert to (bad) HTML, that's not really a problem in Office is it?

Students would grow mad at professors who do not keep their site up-to-date, leading to lawsuits pertaining to fair education, etc.

Only in America would somebody sue a professor for not keeping his course notes up to date. How brain dead are you people? It's your job to learn and to go and find information - if all you're going to do is read just the notes for the course the night before the exam, you can't really expect to be able to sue when you fail, can you?

Students with computers at home (i.e., financially stable students) will have access at all times, while others (minorities, etc) will not, leading to an even bigger gap between upper- and middle-class.

I think you'll find that the course notes will still be made available to the students on paper. If not, I'm sure there are some computer labs somewhere with printers.

This project is not about under-mining MIT. It's not about replacing notes with HTML. It's not about giving professors extra workload. It is however, about a 15-year old who has above average intelligence getting free access to professional materials that match his ability from anywhere in the world. You're just angry because you put yourself in debt going to college and seem to think that this proposal will replace a degree. It won't, but I suspect you don't have one anyway, huh?

I have to say, I think this is a great idea. I'm sure UMIST would do this at some point themselves, but I understand the main problem is with copyright retention and Universities stealing each other's materials. MIT is showing the rest of the world the way it should be done from now on.
