Art of Problem Solving is a good web site for math enthusiasts, and their "Beast Academy" books may interest your son. A math curriculum I like is Singapore Math. I suggest searching the Davidson Gifted Forum http://gif

They can only do so with error, but I bet that a higher percentage of country music fans than rap music fans are Republican. Given racial voting patterns, "white" genres of music will tend to have more Republicans.

This change does not affect me, but I don't want to be pressured into referring to a male as female if he really is a male. Part of the transgender agenda is forcing others to accept such "gender identities". I don't wan

"All people are the same: race does not matter." In the U.S. whites score about one standard deviation above blacks on IQ tests such as WISC and Stanford-Binet, and in adoption studies that try to control for environment, this dif

I wish Guido van Rossum had left well enough alone, so that the above line was valid code in current Python (it works for Python 2, not Python 3).

The article's criticism of IIT and IIM (elite Indian universities) could be made of the elite U.S. schools too: "The short point: our system is designed to keep people out, not get them in. The true value of an IIT or IIM is not t

I buy Windows computers from HP and Dell and hardly notice the difference between the two companies. I don't worry that they might stop producing PC's, because I am sure somebody will.

Fortran 90 and later versions of Fortran have array operations, as in Matlab, but you can also write loops and have the compiler optimize the code. There already is a high-level language for scientific computing with C-like performance.

Maybe 100K LOC in a dynamic language is more difficult to maintain than 100K LOC in a statically typed language, but what if the same functionality requires 500K LOC in the statically typed language? It is easier to maintain a small code ba

Btw, Fortran arrays start at 1 by default, but the lower bound can be specified by the user, for example real :: x(-10:10) is a real vector of 21 elements from -10 to 10.

"I want a language to be a tool that I can use to solve scientific and engineering problems with minimal conceptual overhead due to minding language features." Among compiled languages, isn't that Fortran, especially since Fo

The reason for a Female Founders Conference is presumably that women are under-represented among founders. A quote from Paul Graham may explain why: http://www.paulgraham.com/start.html "One advantage startups have ove

Arrays in Fortran 90+ are a powerful feature -- there are whole array operations and operations on array slices, as in Matlab and Python with numpy. It's easy to allocate multidimensional arrays. Compilers are good at optimizing code -

I see many books on Python listed. It's a good language for data analysis and scientific computing, especially with scipy, but there are alternatives, of course. I like Fortran 95, which is available in gcc as gfortran. A relevant book

If data is drawn from a Laplace distribution of the form p(x) = exp(-|x|), the mean absolute deviation is more informative than the standard deviation, but if its form is close to the normal, p(x) = exp(-x^2), the standard deviation is more

PC's with 2-3 terabyte hard drives and 8+ GB of RAM are not that expensive, and download speeds are fast with broadband, which allows "excess" resources to be used to obtain and install a Linux iso within Windows using Virtua

Much of our ruling class graduated from selective universities with legacy preferences and "development" cases. Making a stink about nepotism in China is hypocritical.
