4. C# is programming language Programming languages allow us to communicate with the computer. Just as English is a verbal/written language to allow us to communicate with other people. We can’t speak with computers, we can only write to them. This written language is called a PROGRAM! C# programs are written in text then compiled (translated) from text to binary machine language that the computer understands.

25. The rise of mathematics is heating up the job market for luminary quant's, especially at the Internet powerhouses where new math grads land six-figure salaries and rich stock deals. Tom Leighton, an entrepreneur and applied math professor at Massachusetts Institute of Technology, says: "All of my students have standing offers at Yahoo! and Google. Top mathematicians are becoming a new global elite. It's a force of barely 5,000, by some guesstimates, but every bit as powerful as the armies of Harvard University MBAs who shook up corner suites a generation ago.
