Example text

Scale = 1,000:1 = 103 41 −4 The electron microscope helps us to get an idea of the shapes of some of the living creatures. We see a diphtheria bacillus (1) and a colon bacillus (2), which itself is being attacked by bacteriophages (3), as well as a smallpox virus (4). We see how keratin of the skin is curling up (5) before falling off. Some gold leaf (6) left on the girl’s hand, possibly from book binding, demonstrates its extreme thinness; in fact this gold leaf is so thin that you could use it to cut a bacterium, such as is depicted near it, in two, if only you could hit it.

As to the oxygen molecules (3) moving in the air, their average speed at a temperature of 10o Centigrade (= 50o Fahrenheit) would be 470 meters per second (= 1,000 miles per hour) in reality. In the image that speed would be 108 times greater, that is, more than 100 times the speed of light! In the inset the helical structure of the flagellum which could be recognized in −7 can no longer be seen, as again only hydrogen atoms are indicated, and all other atoms behind them (oxygen, carbon, and nitrogen) are left out.

In picture = 10−7 cm. 001 micron. Scale = 10,000,000:1 = 107 45 −8 The sodium (1) and chlorine (2) atoms of the salt crystal are clearly indicated. The shading here and in later pictures has only a symbolic value: a darker grey only means that the probability is greater that an electron will be found there than in a place that is more lightly shaded. As to the oxygen molecules (3) moving in the air, their average speed at a temperature of 10o Centigrade (= 50o Fahrenheit) would be 470 meters per second (= 1,000 miles per hour) in reality.
