It is thus probable that germs of the lowest organisms known to us are continually being carried away from the earth and the other planets upon which they exist. As seeds in general so most of these spores thus carried away will no doubt meet death in the cold infinite space of the universe. Yet a small number of spores will fall on some other world and may there be able to spread life if conditions be suitable. ~ Svante Arrhenius 1859 to 1927 - Physical Chemist
Science is the acceptance of what works and the rejection of what does not. That needs more courage than we might think. - Jacob Bronowski 1908 to 1974 Mathematician Biologist
