Avogadro Quotes (1 quote)
Astronomers tell us that there are about 1023 stars in the universe. That’s a meaningful number to chemists—an Avogadro number of potential solar systems of which between 1 and 50 percent are estimated to have planets. … Planets are plentiful—and from this fact we can begin our exploration of how life might have evolved on any one of them.
