Features
Electroluminescence
When a luminescent substance such as zinc sulfide is placed in an alternating electric field, it emits light. This effect makes possible thin illuminating panels and many other useful devices...
How Fishes Swim
In which the speed of small fishes is measured in the laboratory and their power calculated. Similar observations in nature suggest that water may flow over a dolphin completely without turbulence...
The Ear
It translates sound between some 16 cycles per second and 20,000 into nerve impulses. Together with the auditory centers of the brain, it is an instrument that is not only remarkably sensitive but also selective...
The Plasma Jet
Magnetohydrodynamic effects in an electric arc generate a beam of electrons and ions with a temperature of 30,000 degrees F., the highest maintained beyond an instant by a man-made device...
Single Human Cells in Vitro
when a suspension of bacteria is spread on a layer of nutrient, each bacterium gives rise to a colony of genetically uniform descendants. The same thing can now be done with cells of various human tissues...
