4.3 Gamete production in men

A sexually mature man is producing sperm all the time at a rate of around 300–600 per gram of testis per second. This provides the 500 million or so which are released at each ejaculation. But the formation of an individual sperm takes about nine weeks (64 days). Sperm are produced in the testes, and production is most efficient at a temperature several degrees lower than the normal body temperature of 371°C. For this reason the testes (plural of testis) are suspended outside the body cavi

Birding at the Museum: Artists Behind the Dioramas
Long before sophisticated wildlife photography, artists in the field captured the color and movement of birds for the background paintings of the Museum's dioramas. Similarly, bird taxidermists studied their subjects' anatomy and behavior to achieve a natural effect, most dramatically in flight. Here, long-time exhibition artist Stephen C. Quinn explores the work of painters Louis Agassiz Fuertes and Francis Lee Jacques and taxidermist David Schwendeman. VIDEO CREDITS: MUSIC "Missive Accomplis

3.2 Recording on the wire

A paper published by Oberlin Smith in an 1888 issue of Electrical World discussed the possibilities for recording sound using the property of magnetism. He envisaged a cotton thread impregnated with steel dust passing through a coil carrying a current controlled by a microphone. The variations with the sound in the strength of the current would cause corresponding magnetic fluctuations in the magnetic medium. Unfortunately he dismissed his idea because, as he said in his paper, he thou
