'Smart growth' destroys the environment. 'Dumb growth' destroys the environment. The only difference is that 'smart growth' does it with good taste. It's like booking passage on the Titanic. Whether you go first-class or steerage, the result is the same.
First you guess. Don't laugh, this is the most important step. Then you compute the consequences. Compare the consequences to experience. If it disagrees with experience, the guess is wrong. In that simple statement is the key to science. It doesn't matter how beautiful your guess is or how smart you are or what your name is. If it disagrees with experience, it's wrong. That's all there is to it.
As a child, I wanted to know how things worked and to control them. With a friend, I built a number of complicated models that I could control.
Basic research is what I am doing when I don't know what I am doing.
A single neuron in the brain is an incredibly complex machine that even today we don't understand. A single 'neuron' in a neural network is an incredibly simple mathematical function that captures a minuscule fraction of the complexity of a biological neuron.
The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.
