Two objects exert a force of attraction on one another known as "gravity." Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion. The force tugging between two bodies depends on how massive each one is and how far apart the two lie. Even as the center of the Earth is pulling you toward it (keeping you firmly lodged on the ground), your center of mass is pulling back at the Earth. But the more massive body barely feels the tug from you, while with your much smaller mass you find yourself firmly rooted thanks to that same force. Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance.
The Newtonian laws of motion have excellent predictive powers.
Sciences dealing with fuzzy data (human behaviour, climate) sometimes can't predict twenty-four hours ahead (Mr. Fish).
But as a very large driver in any election is the economy, I will be giving more credence to a self-made billionaire who has experience running an incredibly large company employing hundreds of people.
Smartest man in the world? I guess that depends on your definition of smart, clever scientific man he is but unfortunately due to his condition he does not really live in the real world.
And remember many clever people with a high IQ have low common sense.
He has reached an opinion based on his circumstances and the way he lives. So that is fine and his prerogative, personally I disagree with him vehemently .
I'm sure SD can speak for himself, but for my part I don't expect anyone to vote Labour just because Hawking says so. But then the same goes for Lord Sugar and not voting Labour.
Oh and, by the way, *everyone* lives in the real world.
