Either he left the answer in the question or asked for another term for it. Only one I know of is Kala Azar (Hindi for black fever)...

Welcome to the forum.

Your country's not to blame as most education boards have adopted a system of rote learning.Best thing you can do is go with the flow, get good grades and do some studying on the side. It gets better in university.

I think it is a terrible way to promote the more "liberal arts type" education. It was the primary reason as to why I decided not to even apply to Chicago or Columbia.

What languages do you guys code in? As for me: BASIC, JB(Just Basic), RB (RunBasic), VB (Visual Basic), COBOL, FoxPro, Liberty Basic (LB), Python, C#, C, C++ and Java. That was compiler and IDE based. As for web: HTML (no duh!), CSS (no duh x2! (not factorial)), PHP,, JS, Ajax and Flash. I am fluent in most so...

It is funny how in the past 2 years, I have almost exclusively been using MATLAB, Mathematica, C++ and Fortran (also somewhat Java and Python, although I'm getting less and less impressed with the scientific computing abilities of those two languages, although Python isn't too bad). Obviously that led me to forget the specific details of most of the other languages, except C and PHP (at least I think).

If you're looking for problems, Project Euler is a very good site (although you must know programming for most of the problems).

Merry Christmas to you too.

hi BonaviaFx

Don't want to join up to that, sorry.  Why not just tell me the name, exam board etc.  I'll find it from there.


You don't have to download a program, you can just download the file.

But anyway, here is another direct site: … 5/AM27.pdf

I only know graphing in two variables. Linear inequalities, slopes etc etc

A quadratic equation is in two variables. y = x^2 + x - 6

Now, since Shivam is here, I guess we could request him to explain the idea. He has probably tried working in that field too.

Which idea?

Physicist do not think they are god, most do not believe in god.

Actually, a survey conducted by APS showed that while theist physicists are in the minority, but not by much.

I learned a significant amount of things about Wilson loops today.

#24 Re: Euler Avenue » What had you learned today that you found interesting? » 2014-12-02 09:26:13

I learned about the collisionless Boltzmann equation and baryon asymmetry today (well, not for the first time, but more in detail).

#25 Re: Science HQ » When would the eight planets line up? » 2014-11-30 13:46:17

They never line up perfectly. Planetary alignment does occur but it usually is between 3 or so planets with a discrepancy of around 30 degrees. The last time all planets came in an alignment of 30 degrees was in, I believe, 500. The next time should be around 2800. Each such alignment occurs every 500 years and there is usually a 30% chance of it being aligned within 30 degrees.
