Quote of the day

He who dreams. . . does not know he is dreaming. . . . Only when he awakens does he know he has dreamt. But there is also the great awakening (ta-chiao), and then we see that [everything] here is nothing but a great dream. Of course, the fools believe that they are already awake-what foolishness! Confucius and you, both of you, are dreams; and I, who tell you this, am also a dream.

Hover boards, unfortunately, currently violate the laws of physics. Supermagnets exist, but they have to be cooled to near absolute zero, and they are extremely expensive. So Michael J. Fox's hover boards are not possible until we invent room temperature super conductors.

As Heinz Pagels has said, The challenge to our civilization which has come from our knowledge of the cosmic energies that fuels the stars, the movement of light and electrons through matter, the intricate molecular order which is the biological basis of life, must be met by the creation of a moral and political order which will accommodate these forces or we shall be destroyed. It will try our deepest resources of reason and compassion.

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.

The human mind has a desire to know its place in the universe and the role we play in the tapestry of life. This is actually hardwired into our brains, the desire the know our relationship to the universe. This was good for our evolution, since it enabled us to see our relationship to others and to nature which was good for our survival. And it is also what drives our curiosity to understand the universe.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

No one knows when a robot will approach human intelligence, but I suspect it will be late in the 21st century. Will they be dangerous? Possibly. So I suggest we put a chip in their brain to shut them off if they have murderous thoughts.
