Quotes about Physics

You must have carbon. Arsenic, boron, and silicon are the only other elements on which complex molecules can be based, but arsenic and boron are relatively rare and, where concentrated, poisonous to life, and silicon can hold together no more than about a hundred amino acids. Only carbon yields the chemical bonding stability and bonding complexity that life requires. Given the constraints of physics and chemistry, we now know that physical life must be carbon-based.

Aristotle had discovered only half the principle of inertia—that a body at rest remains at rest unless moved by another—but not the other half—that a body in motion remains in motion unless acted on by another.

Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.

I am now convinced that theoretical physics is actually philosophy.

God is an awesome mathematician and physicist.

I am now convinced that theoretical physics is actual philosophy.

If I want to understand the laws of physics I have to first believe what I read about physics. I have to have faith in what I read.

Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes.

But in the science of physics, power means something different. Power describes how fast you use energy. For example, it takes the same amount of energy to walk across a football field as it does to run across a football field. But running is faster. Therefore, running has more power. This is the kind of power that makes things happen.

If I want to understand the laws of physics I have to first believe what I read about physics. I have to have faith in what I read.

Cosmology is a rapidly advancing field.

The faster you go, the shorter you are.
