Man has made this exquisite beverage for 6,000 years, but it is only in the past century that he has begun to understand the subtle enzyme chemistry and microbiology of the process
Self-Reproducing Machines
In which simple units are built which assemble themselves into larger units, which in turn make copies of themselves from other simple units. The process sheds light on the self-reproduction of biological molecules...
Junction-Diode Amplifiers
They are simpler than the maser, quieter than the vacuum tube. Their low internal noise permits them to amplify radio signals much too faint for conventional receivers
