Why is this completely necessary? What would be an acceptable proof to you of this statement?

Sort of. The way I was taught, a progression is called arithmetic because each term is the arithmetic mean of its predecessor and successor, i.e. if A comes before a term X and B comes after a term X in an arithmetic sequence, then X = (A+B

I believe the paper the author is referring to is Franks, John. "Flow equivalences of subshifts of finite type." Ergodic Theory and Dynamical Systems (1984). 4:53-66. Cambridge University Press. Also, minor errors in mathematics papers are

There are two biographies that I think should be required reading for wannabe Silicon Valley entrepreneurs: (1) High St@kes, No Prisoners by Charles H. Ferguson and (2) The New New Thing by Michael Lewis, about Jim Clark And two that, w

In linear algebra, for a given linear transformation (a certain kind of matrix which generally represents some operation) M, an eigenvalue of M is a scalar c such that given a non-zero vector v (called the eigenvector), Mv = cv, where multi

Write the idea down somewhere. However, ideas are a dime a dozen and are essentially useless unless you have a viable plan of attack. For instance, I would love to work on something world-changing like time-travel, teleportation, or anti-gr

To me, the article isn't saying to abandon the road to mastery, but merely to take some detours once in a while. Dedicating a lot of time and energy to something is definitely fulfilling and has a compounding effect, but as many astute prog

In my experience, reading papers with math gets a lot faster as you get used to the conventions. It used to take me almost a whole day to digest a single math or CS paper in a field I was familiar with, but now I can get through a couple in

That certainly seems true, but how much of that is because by doing so you get to go to a school like Caltech, Harvard, or MIT? A more interesting question to me would be whether American IMO contestants have a better chance of doing good m

From what my high school math teacher told me, it's because the modern U.S. curriculum was last drastically revamped in wartime to pump out future engineers and physicists, which is why there is so much emphasis on trigonometry and calculus

From the real number axioms: Let x \in R. Then we have that x*0 + x*0 = 0*x + 0*x = (0+0)*x = 0*x = x*0 by commutativity of multiplication, distributivity, the existence of a neutral element 0 for addition, and the commutativity of m

Because the concentrated effort needed to "not do something" seems to increase the likeliness that you will do exactly that, especially under stress. For some reason, it seems that it is not the will or intent of the thinker that is importa

It also tends to work better than not telling anybody about it at all. If you tell people that you are quitting something, there is a social pressure on you to follow through on your promise. Your friends and family might also be willing to

Some schools are fighting back against this. For example, I know that the UCLA math department has a policy that professors are required to search for a replacement textbook once a textbook goes beyond the third edition, unless there is a s

I'm glad I'm not the only person who has #3. For some reason, I seem to get miraculous insights into problems when I'm exercising, so I've taken to keeping a tiny pen and a couple index cards within reach at all times. While running, this h

"It's not a shortcoming, it's a feature!" While I am now an Apple fan, this reminds me of the ridiculous excuses Apple fanboys gave me when they compared their early-generation iPods to my MP3 player at the time (a Rio Karma). "It doesn

Does anybody here know somebody that has used this program to aid their learning of computer science concepts? It's certainly an admirable cause, but is this a better introduction to programming than something like Logo, which has been used

These are the times when I wish that this technology was open-source (correct me I'm wrong), so if it was lacking, it could be added. I would love to have some similar way of turning commutative diagram sketches into TeX-ready form. It woul

No way. There are tons of people in the sciences with very interesting lives, they just don't have people knocking down their door to write popular biographies like Feynman, Erdös, or Tesla. I say that living mathematicians like John Nash J

The reason that short, frequent publishing is so pervasive on the web is that you have to compete with everything else on the internet that is shiny, flashing, and begging for your attention. I think that we, as humans, have a predilection

A good way for me to maintain motivation when slogging through information-dense nonfiction books (like textbooks, programming language manuals) is to read through actively (writing notes/questions in margins or post-its) and then to quickl

In my opinion, the original quote by Aldous Huxley is more accurate: "An intellectual is a person who has discovered something more interesting than sex." [ http://en.wikiquote.org/wiki/Aldous_Huxley ]

First of all, I am no expert in psychology, and most of my exposure to it was through readings in AI courses. For a good example of a milestone in modern psychology, consider the Rescorla-Wagner Model--an attempt to model classical (Pavlovi

I really dislike it when people (especially people of a technical mindset like math/physics/CS majors) summarize the above article in the way, and use it to justify their dislike of the social sciences. It's not about the problems of method

Also consider that if you're a musician, people are less likely to say that they dislike music to your face, out of politeness. I don't think it's so much cultural pressure as it is unusual. It's like meeting somebody who doesn't like art.

If I could choose one book on sales, it would be Non-Manipulative Selling by Tony Alessandra. This is a diamond in the rough among sales books. Many other books on sales, at least in the few that I've read and others I've skimmed, seem to b
