Say “oooh” as in “noodle.” Then say “aaah” as in “park.” When you say “oooh” your mouth is more closed, with less resonating space and a smaller opening. This configuration blocks the higher overtones of your voice. When you say “aaah” your jaw and lips open, creating more resonating space and letting more high overtones …

Do computers think? Is the brain a computer? We use computers as metaphors for the brain and vice versa. Is the comparison apt? Brains and computers can imitate each other in limited ways. Deep down, how much similarity is there?
Engineers describe a system whose input and output behavior are known and whose inner workings are otherwise mysterious as a black box. Bruno Latour describes the black box as: the way scientific and technical work is made invisible by its own success. When a machine runs efficiently, when a matter of fact is settled, one …
The parts of the computer that do the “thinking” are mostly made of little electronic switches called transistors. If you connect two wires to a transistor, you can use the voltage on one wire to control the voltage on the other. What’s especially handy for engineering purposes is that the presence or absence of a …
How do you get sound in and out of a computer? There are two steps. You have to turn the sound into electricity, and then you have to turn the electricity into numbers.
