We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Stephen HawkingRead
Not to leave planet Earth would be like castaways on a desert island not trying to escape...Sending humans to other planets ... will shape the future of the human race in ways we don't yet understand, and may determine whether we have any future at all.
Interpretation
Exploring other planets is crucial for the survival and evolution of humanity.
In this quote, Stephen Hawking emphasizes the importance of space exploration for the future of humanity. He compares the act of not venturing beyond Earth to being stranded on a deserted island without attempting to escape, underscoring his belief that our endeavors in space could significantly impact our survival and evolution, even in ways we cannot yet foresee.
In practice
This quote can be used to inspire students in a science class about the importance of space exploration.
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.
Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by the authors to save the appearances, exist only in the imagination.
I often compare open source to science. To where science took this whole notion of developing ideas in the open and improving on other peoples' ideas and making it into what science is today and the incredible advances that we have had. And I compare that to witchcraft and alchemy, where openness was something you didn't do.
Every great advance in science has issued from a new audacity of imagination.
As we get better at understanding how little we know about the body, we begin to realize that the next big frontier in medicine, is energy medicine. It's not the mechanistic part of the joints moving. It's not the chemistry of our body. It's understanding for the first time how energy influences how we feel.
Wherever there is a design that is highly successful in a broad range of similar environments, it is apt to emerge again and again, independently - the phenomenon known in biology as convergent evolution. I call these designs 'good tricks.'
If there is a small rocket on top of a big one, and if the big one is jettisoned and the small one is ignited, then their speeds are added.
