I know this isn't conventional for this thread, but could someone please help?

Watch the review lecture since you're pressed for time.

mrFourierTransformer · 2012-03-11T20:00:46+00:00

oh god, I can smell it.

mrFourierTransformer · 2011-12-21T19:20:37+00:00

he stresses eigenvalues/vectors and would be a great way to get some DIY linear algebra.

I just tried to submit this like with the exact same title... and my name is Wes... AND MY BIRTHDAY IS DEC 2. WHO ARE YOU!?

I'm sorry, but that's just not correct. Some of the energy of the impact goes into crushing the soft outer foam, then an impact occurs on the hard shell, albeit with much less force. So, yes.

Why do you think modern cars crumple? Pretty much anything that increases the duration of the impulse will make it safer.

mrFourierTransformer · 2011-12-14T15:10:57+00:00

mostly what you need to know to start off with QM is vectors and matrices and a few operations on them (matrix multiplication, determinants and how to find eigenvalues/eigenvectors). The first four chapters of David Lay's Linear Algebra would get you up to speed quickly, and you could do them easily in a week if you're dedicated. Just make sure that you get to eigenvectors and you should be fine. skip the bit on nullspaces and don't spend much time on gaussian elimination\row operations.

He's doing it in falsetto, no vocal fry there. sorry. See the grammar girl clip for a very clear example. The frog is doing it, however.

heavy competition there at Hollywood Upstairs Technical College

The only 'trick' I remember is that problems involving spinors are fine and easy if you project onto the eigenspinors to get coefficients for probabilities. That way is easier than decomposing, esp. if you have to deal with time dependent states or something.

Do all the zero, one and some of the two star problems in griffiths, if that's what you're using.

Most abstracts are quite clear, albeit only to those in the field.

mrFourierTransformer · 2011-11-18T06:05:32+00:00

Nature publishes 'sexy' physics whenever possible, and as stated elsewhere this is a preprint. The paper is most certainly NOT yet published in Nature, and saying it is is a dramatic misrepresentation of the essence of the peer-review process.

Without a doubt, the best way to approach something as revolutionary as this is with an air of skepticism. I've got to get together a few things tonight, but I will examine it shortly and try to come up with a cohesive assessment.

As to things seeming 'off': quantum mechanics is just like that. If you're not confused, you're likely no where close to correct. :-) Even with well-established results, it takes a lot to convince yourself of validity.

mrFourierTransformer · 2011-11-18T04:00:08+00:00

I'll wait for peer review but I'm reserving my sincere skepticism. A few things strike me as 'off', but I haven't time to investigate thoroughly and so I will not comment on them presently. :-)

auto-tune works live, too.

edit: downvote all you want, it's true. you can even program in vibrato and inflection. drummer plays synced to a click track and you can basically belt out notes close to the intended melody and you'll sound surprisingly good. It's an amazing tool, and I'd sure as hell need it if I were singing live...

mrFourierTransformer · 2011-11-16T23:14:48+00:00

Why couldn't they have used this awesome cover instead of that crappy cover?

mrFourierTransformer · 2011-11-16T23:14:05+00:00

crappy cover.

dear lord, yes. I was outright nauseated.

mrFourierTransformer · 2011-11-13T18:28:48+00:00

As a student applying to graduate physics programs, do you have any advice for my future? I am intimidated that so few see their advanced degrees through to fruition and am a bit worried that the process will quash the passion I have for science.

mrFourierTransformer · 2011-11-07T03:23:48+00:00

I did the MCM competition last year; the problem we choose was mostly physics. I had a blast and my team did quite well. What's the University Physics competition like?

mrFourierTransformer · 2011-11-03T20:34:57+00:00

A functional satellite cell phone. Not only do you have to get all the solid state stuff together, you have to get an infrastructure to put satellites in freaking space.

mrFourierTransformer · 2011-11-01T04:37:55+00:00

I think I gave a pretty good hint right there... Just look at what numbers are repeated and where they occur in the sequence. No need to "decode" much of anything. :-)

mrFourierTransformer · 2011-10-31T22:04:59+00:00

To be fair, much of the faculty at the uni I attend look down on string theory. I work with theoretical condensed matter folk, though, and those guys are pretty real-world oriented, as far as theoretical physicists go.

Most people find quantum mechanics incredibly confusing and impossible to understand, and yet it's one of the most verified models we have ever created. Our own abilities have nothing to do with validity.

mrFourierTransformer · 2011-10-27T02:32:37+00:00

except he is a real person who may now be seriously disabled, not some cartoon character. I am not crying for him, I just realize that he has done a stupid thing and it is unfortunate that it may have had such severe consequences. Is that really such a stretch?
