We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Stephen HawkingRead
Imaginary time is a new dimension, at right angles to ordinary, real time.
Interpretation
Imaginary time provides a theoretical framework that contrasts with our traditional understanding of time.
In this quote, Stephen Hawking introduces the concept of imaginary time, suggesting that it offers a new perspective on the nature of time itself. Unlike ordinary time, which is linear and subject to relativity, imaginary time exists in a dimension that could potentially allow for a more comprehensive understanding of the universe, challenging our conventional notions and opening up new possibilities in theoretical physics.
In practice
In a lecture on theoretical physics, this quote can be used to explain concepts of time.
We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
In my opinion, there is no aspect of reality beyond the reach of the human mind.
Imagination alone is not enough, because the reality of nature is far more wondrous than anything we can imagine
The investigation of nature is an infinite pasture-ground where all may graze, and where the more bite, the longer the grass grows, the sweeter is its flavor, and the more it nourishes.
Yes, I am the last man to have walked on the moon, and that's a very dubious and disappointing honor. It's been far too long.
Science offers the chance to cure debilitating and once-intractable disorders like hemophilia and sickle cell disease. But we need to make sure the ability to access these therapies, or the risk that someone can be locked out of them, doesn't widen gaps between the rich and poor.
We need to look at NASA, not as a handout, but as an investment.
The best way to conduct research on a larger scale is to make sure everyone knows what everyone else is doing... The sooner the better - start talking to other people about what you're doing. Because that's what will stimulate things the fastest.
