The physical sciences have advanced far beyond our imagination. A short 75 years ago we had a “supercomputer” that took up a full room. The machine was huge, weighing 30 tons, using 200 kilowatts of electric power. It contained over 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors. It spit out punch cards for programmers to decipher. Now we have a Smartphone – a supercomputer that fits in ones hand and is 5 million times faster.
A supercomputer that can access anything anywhere in the world, we have any information we want just by asking this phone. It will track us in real-time anywhere we are, allow us to talk to anyone in the world, all from a 6” x 3” flat object in our hand. But the brain has yet to be solved by the Science community.
