Hans Dieter Baehr,Karl Stephantet man sie aber mit einer Lupe aus der Nähe, sagen wir aus 5 cm Entfernung, dann unterscheiden sich die in etwa 9500 bekannten Ameisenarten so stark voneinander wie Elefanten, Tiger und Mäuse. Schon allein die Größenunterschiede sind sagenhaft. Eine gesamte Kolonie der kleinsten Ameisen, z.B. eine

Thermal radiation,resence of matter; electromagnetic waves also transfer energy in empty space. Temperature gradients or differences are not decisive for the transferred flow of heat, rather the difference in the fourth power of the thermodynamic (absolute) temperatures of the bodies between which heat is to be trans
