Whoa - he didn't put a time scale or units on his graph are we looking at one month, one year, or 50 years? His graph definitely looks more attractive but I would add that it's very important to put scales and units on your graph. And don'

Hey no offense but I'm guessing that you haven't spent very much time interacting with children that aren't your own. In my experience children lie and dissemble and deceive before they learn to talk. Think about all of the crying and mal

Picking a bike lock is pretty impressive - I had to resort to a battery powered masonry saw when I was in this situation. In high school I made my own set of lock picks only I used hacksaw blades and a bench grinder. One of my friends in

I'm very unimpressed - I had high hopes alas, here are some real queries from my lab where google gives me the right answer within 1-2 links. (or I can reach for the CRC handbook) W|A Q: speed of light in glass A: c (speed of light) and sma

This part I found particularly interesting: (if true) "War had been extraordinarily profitable for the German economy. By 1948 - despite six years of conflict, Allied bombing and post-war reparations payments - the capital stock of assets s

Wow this is really depressing to contemplate. Has anyone here been through the experience where you went to grad school for curiosity and found that it made you unemployable? I really fear this outcome. I went to graduate school because I

Hey as long as he's not breaking a law, it's a free country he can do whatever he pleases. I think I understand the origin of this sentiment - $tanford has people beating down it's doors to get in and 10 ambitious amazing kids were rejecte

I've heard that the soft drink 7-up once contained lithium among its ingredients. I don't think it's a good idea to add lithium to drinking water because of its toxicity, but I don't see anything intrinsically wrong with adding chemicals p

I'm not sure if the t'Hooft page is a joke or not. Looking over the Herring Box is a humbling experience. A common hope that a lot of children have is that even though there was no way that anyone could read every book in the library it

To get an idea of the amount of work required to gain "depth" consider these famous lists: HOW to BECOME a GOOD THEORETICAL PHYSICIST by Gerard 't Hooft This is a web site (still under construction) for young students - and anyone else - wh

Well you are right that these articles tend to be overly optimistic, but I wouldn't say that it never happens. The most conspicuous example I can think of is: Giant MagnetoResistance (GMR) read heads. These went from a laboratory discove

I like this idea except for the part about investigative teams being more activist. I think that having a political agenda, even a completely overt one, undermines the credibility of such a team.

This is the kind of thing that should be picked up by statistical parsers which presumably use patterns like this to choose the "correct" parse of a sentence from the multitude of possibilities. Of course it is more meaningful when a human

I think I honestly prefered the tables, despite their flaws - although he makes some good points. Maybe it just takes some getting used to.

Whoa, that's awesome! My advisor got to take Emag from J.D. Jackson himself - Taking a course from the author of a famous text is truly the kind of thing that you get permanent bragging rights about.

So this is why Mermin and Ashcroft's Solid State Physics has been one of the standard graduate texts for the field since it was published in '76. According to Wikipedia Lev Landau ranked physicists on a log scale - Newton was 0, Einstein 1

I think that the biggest limitation is the number of qualified teachers. Surely not everyone has the aptitude to learn these ideas, but of those who do only a tiny fraction are given access to quality instructors. It was definitely not a

yeah this was a pretty lame introduction, but there are several BIG ideas in lagrangian and hamiltonian mechanics that I think would be entirely appropriate for HS - in fact the earlier people are exposed to these the better. (1) The loca

I've heard this theory floated before. The people proposing it have a good point. They have to find something to do with all of these young men or trouble could emerge. I guess an alternative strategy would be to bring back monasteries.

These remind me of Doug Hofstadter's "Parquet Deformations" in metamagical themas. Good stuff.

Thanks for the link - these results are encouraging. I'll think about it - if I come up with anything I'll let you know. Good luck.

I apologize for threadjacking but you guys might be able to help. I have a different problem - I would like to compute an approximate SVD of a very large sparse matrix, (for spectral clustering) but I can't find a good implementation whic

you have a good point, but for what it's worth here's the practical example that is the basis of my opinion on this. I had a very large corpus of text and I wanted to construct a word association graph. This involves multiplying together
