The present crisis in science and science education (expressions like
"terminal decline" and "farewell to physics" have become commonplace)
has many and various sources and is probably irreversible. Still, in a
desperate counterattack, two fundamental falsehoods should be dealt
1. The false conclusion of Clausius according to which all heat engines
working between the same two temperatures have the same maximal
efficiency should be replaced with its negation: Heat engines working
between the same two temperatures could have different maximal
efficiencies. Then all possible deductions should be made.
2. Einstein's false second postulate according to which the speed of
light is independent of the speed of the light source should be
replaced with its negation: The speed of light does depend on the speed
of the light source. Then all possible deductions should be made.
