Thinking about quantum physics is like unraveling your brain and putting it back together again upside down. Much like studying Kabbalah.

But while doing that I'd been following a variety of fields in science and technology, including the work in molecular biology, genetic engineering, and so forth.

What is innovation if not our ticket to every business interest in the world? It's the ticket to solving the world's problems - the energy problems, the pollution problems, the global warming problems. If it isn't for science and engineering, how will we compete in the new world?
