Every evening, I come home tired and have just enough energy to fill out the endless tax forms, to pay bills, not to let my house neglected and to hear the radio concert for an hour.
Fritz ZwickyMountains were once my big adventure but is is over since a long time; I still dream from the wonderful days sometimes, read also a few pages from a mountain book. But the thought of doing again active mountain climbing has faded.
Fritz ZwickyWith all reserve we advance the view that a supernova represents the transition of an ordinary star into a neutron star consisting mainly of neutrons. Such a star may possess a very small radius and an extremely high density. As neutrons can be packed much more closely than ordinary nuclei and electrons, the gravitational packing energy in a cold neutron star may become very large, and under certain conditions may far exceed the ordinary nuclear packing fractions.
Fritz ZwickyI soon became convinced... that all the theorizing would be empty brain exercise and therefore a waste of time unless one first ascertained what the population of the universe really consists of.
