Stephen William Hawking CH, CBE, FRS, FRSA is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation. Hawking was the first to set forth a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He is a vigorous supporter of the many-worlds interpretation of quantum mechanics... (wikipedia)
Intelligence is the ability to adapt to change.
My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit as well as physically.
I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.
Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.
People won't have time for you if you are always angry or complaining.
However difficult life may seem, there is always something you can do and succeed at.
I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.
If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans.
Science is not only a disciple of reason but, also, one of romance and passion.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
