Amplitude Modulation, or AM, works by modulating the sound on the "peaks and valleys" of the frequency. If you were to look at the waveform of the carrier frequency, you would see it as variance in the "power levels" of the signal, going higher and lower depending on what's being sent.

Because of how AM works, you can actually hear what's being transmitted by causing an electrical arc. It's the same concept of hearing a "buzz" from high voltage power lines, except in a controlled fashion to produce sound.

All work and no play makes Sally a dull boy. Or whatever. But seriously: don't over-work yourself. I mean if you really want to, go for it, but the quality of your work will decline with you. Meet some new people, go hiking, go outside, eat better, live better, work better, and your work will look better with you.

Re:Ask HN: Would you still by Apple stock? on Wednesday February 29, 2012 @09:47PM (#3650707)
Yeah, there's still time to buy Apple Stock. I asked myself the same thing this time last year when it was around $300. Prediction: $800 by 2014.
Re:Attention Comp Sci Majors: on Monday August 29, 2011 @06:39PM (#2939353)
yeah, I probably wouldn't call "the 37signals guys" script kiddies, David Hannson created Ruby on Rails. I agree with your take on innovation, Pandora would be in the same boat.

Attention Comp Sci Majors:

To all of you Comp Sci majors out there: How well has the major prepared you for programming modern frameworks and languages? Will the work pay off for someone who wants to learn frameworks like RoR or languages like HTML5, CSS3? I'm asking this because with comp sci, you usually need to take heavy math courses. Would a programmer be better off going into design so he/she has more time to teach...
