We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

As those who have seen Jurassic Park will know, this means a tiny disturbance in one place, can cause a major change in another. A butterfly flapping its wings can cause rain in Central Park, New York. The trouble is, it is not repeatable. The next time the butterfly flaps its wings, a host of other things will be different, which will also influence the weather. That is why weather forecasts are so unreliable.
Interpretation
Small changes can have large, unpredictable effects in complex systems.
This quote illustrates the idea that minor events can lead to significant consequences, emphasizing the interconnectedness of systems like weather. Stephen Hawking uses the metaphor of a butterfly flapping its wings to highlight the unpredictability inherent in such systems, where even the slightest variation can result in dramatically different outcomes, thus challenging the reliability of predictions.
In practice
In a science class, when discussing chaos theory and its implications on weather patterns.
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.
Some of the best theorizing comes after collecting data because then you become aware of another reality.
People look down on stuff like geography and meteorology, and not only because they're standing on one and being soaked by the other. They don't look quite like real science. But geography is only physics slowed down and with a few trees stuck on it, and meteorology is full of excitingly fashionable chaos and complexity. And summer isn't a time. It's a place as well. Summer is a moving creature and likes to go south for the winter.
At lunch Francis [Crick] winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.
After I give lectures-on almost any subject-I am often asked, "Do you believe in UFOs?" I'm always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I'm almost never asked, "How good is the evidence that UFOs are alien spaceships?"
I tried out various experiments described in treatises on physics and chemistry, and the results were sometimes unexpected. At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience.
There is fuel in every bit of vegetable matter that can be fermented. There's enough alcohol in one year's yield of an acre of potatoes to drive the machinery necessary to cultivate the fields for a hundred years.
