We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Stephen HawkingRead
The increase of disorder or entropy with time is one example of what is called an arrow of time, something that distinguishes the past from the future, giving a direction to time.
Interpretation
Entropy increases over time, symbolizing the directionality of time from the past to the future.
In this quote, Stephen Hawking explains the concept of entropy as it relates to the flow of time, highlighting that the natural tendency of disorder in the universe increases as time progresses. This notion of an 'arrow of time' serves to differentiate between past events and future possibilities, underscoring the irreversible nature of time's passage and its implications in understanding the universe.
In practice
This quote can be used in a discussion about the laws of thermodynamics in a science class.

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.
I think the really cool and compelling thing about math and physics is that it opens up entry to all these hypotheticals - or at least, it gives you the language to talk about them. But at the same time, if a scenario is completely disconnected from reality, it's not all that interesting.
[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.
Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn't even nothing or once.
It may be conceit, but I believe the subject will interest the public, and I am sure that the views are original.
Men became scientific because they expected Law in Nature, and they expected Law in Nature because they believed in a Law Giver.
The idea that you can ask one question and it makes the point - well, that wasn't how psychology was done at the time.
