Quote

With no gravitational force to work against, your body not only doesn't need the same amount of muscle and bone, it starts breaking them down. As on Earth, so in space: use it or lose it. And exercise may not solve the problem.

So while you're getting ripped apart head to toe as you fall into a black hole, you will also extrude through the fabric of space and time, like toothpaste squeezed through a tube. To all the words in the English language that describe ways to die (e.g., homicide, suicide, electrocution, suffocation, starvation) we add the term spaghettification.

With one linear centimeter of your lower colon there lives and works more bacteria (about 100 billion) that all humans who have ever been born. Yet many people continue to assert that it is we who are in charge of the world

I am not the most annoying person to bring to a movie 'cause I basically hold it in and write about it later or tweet about it. The most annoying people to bring to movies, I think we all agree, are those who read the book first.

I know of no time in human history where ignorance was better than knowledge.

I remain fearless of airplanes after 9/11. But during a trip to Los Angeles on a Boeing 767, I couldn't keep my mind from drifting: What's the largest piece of this airplane that could crash into the World Trade Center, explode out the other side, and survive intact? The landing gear? My computer battery? My belt buckle? My wedding ring?

Science, and its impact on a person's livelihood is the common denominator.

Science is like an inoculation against charlatans who would have you believe whatever it is they tell you.

If you are that person, you are more likely to believe that God cured you, this invisible force, creator of the universe, cured you, than that you had three idiotic doctors diagnose you. ... I taught physics to pre-med students who became doctors. Not all of them are smart, I assure you.

The history of science shows that great mysteries get solved. It may be that there's an answer that humans are too stupid to understand. I'm intrigued by that possibility.

I have a personal philosophy in life: If somebody else can do something that I'm doing, they should do it. And what I want to do is find things that would represent a unique contribution to the world-the contribution that only I, and my portfolio of talents, can make happen. Those are my priorities in life.

You say you're worried about kids? I'm not worried about kids, I'm worried about grown ups... Children are not the problem here... We spend the first year of their lives teaching them how to walk and talk, and the rest of their lives telling them to shut up and sit down.
