The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.

One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.

Chemistry is the melodies you can play on vibrating strings.

When I get bored, or get stuck on an equation, I like to go ice skating, but it makes you forget your problem. Then you can tackle the problem with a fresh new insight. Einstein liked to play the violin to relax. Every physicist likes to have a past time. Mine is ice skating.

I like to engage the public because when I was in high school, I had all these questions about anti-matter, higher dimensions and time travel. Every time I went to the library, every time I asked people these questions, I would get some strange looks. Nobody could answer any of these questions.

Remember the movie 'The Matrix,' where virtual information popped up to help inform physical day-to-day reality? Such things won't always be the stuff of Hollywood. If the Internet is accessible via contact lenses, biographies will appear next to the faces of the people we talk to, and we will see subtitles if they speak a foreign language.

Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it. Michio Kaku

No one knows who wrote the laws of physics or where they come from. Science is based on testable, reproducible evidence, and so far we cannot test the universe before the Big Bang.
Michio Kaku

Humans are natural-born scientists. When we're born, we want to know why the stars shine. We want to know why the sun rises.

I am a futurist, projecting trends in science into the next decades and century, but ironically my two daughters - one is a neuroscientist and the other is a pastry chef - tell me that my taste in music is positively prehistoric. Michio Kaku

It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.

You can mass-produce hardware; you cannot mass-produce software - you cannot mass-produce the human mind.
