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

A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.
Interpretation
What this quote means
A good theory effectively explains many observations with minimal assumptions and predicts future outcomes.
Stephen Hawking's quote emphasizes the criteria for a robust scientific theory. It should not only provide an accurate account of a wide range of phenomena with simplicity but also be able to forecast future observations, thus demonstrating its reliability and usefulness in understanding the natural world.

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.

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.

A strong intuition is much more powerful than a weal test. Normals teach us rules; outliers teach us laws. For every perfect medical experiment, there is a perfect human bias.

The radiations that pour upon the earth cause the biosphere to take on properties unknown to lifeless planetary surfaces, and thus transform the face of the earth. Activated by radiation, the matter of the biosphere collects and redistributes solar energy, and converts it ultimately into free energy capable of doing work on earth.

Development of Western science is based on two great achievements: the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility to find out causal relationships by systematic experiment (during the Renaissance). In my opinion, one has not to be astonished that the Chinese sages have not made these steps. The astonishing thing is that these discoveries were made at all.
