Neil deGrasse Tyson

There is no shame in not knowing. The problem arises when irrational thought [...] fill the vacuum left by ignorance.

Knowing how to think empowers you far beyond those who know only what to think.

Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.

We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.

The good thing about science is that it`s true whether or not you believe in it.

The more I learn about the universe, the less convinced I am that there`s any sort of benevolent force that has anything to do with it, at all.

For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You`d be surprised how far that gets you.

It`s the inspired student that continues to learn on their own. That`s what separates the real achievers in the world from those who pedal along, finishing assignments.

The best educators are the ones that inspire their students. That inspiration comes from a passion that teachers have for the subject they`re teaching.

Some of the greatest poetry is revealing to the reader the beauty in something that was so simple you had taken it for granted.

If you need to invoke your academic pedigree or job title for people to believe what you say, then you need a better argument.

Scientific inquiry shouldn`t stop just because a reasonable explanation has apparently been found.

Ignorance is a virus. Once it starts spreading, it can only be cured by reason. For the sake of humanity, we must be that cure.

The Universe is under no obligation to make sense to you.

Science is a philosophy of discovery. Intelligent design is a philosophy of ignorance.
