Many Latino kids should become scientists because we need scientists all over the world from all different backgrounds. We have many tough problems, and we need everybody's help to solve the problems.

One action society needs to take is to use energy much more efficiently. Instead of incandescent light bulbs, you could switch to LEDs that consume a lot less electricity, for example.

The scientists I looked up to at the beginning were not Latino. They were famous scientists of many years ago, like Madame Curie. Later, I realized that there were also, but a very few, Latino scientists. There were good ones, but very few, because there wasn't as much a tradition to be a scientist in our culture. But this is changing.

Laboratory experiments, field observations and atmospheric modeling calculations have now established that chemical reactions occurring on PSC particles play a central role in polar ozone depletion.

Politics follows the lines of physics: every action creates an equal and opposite reaction.

The initial motivation of the experiment which led to this discovery was a subconscious feeling for the inexhaustible wealth of nature, a wealth that goes far beyond the imagination of man.

Part of the scientific temperament is this tolerance for holding multiple hypotheses in mind at the same time.

I don't think immortality is necessarily the key to understanding the world. You have to be careful with what you think you're achieving. I'm all for science discovering amazing and fantastic things about our world, but I think the motivations behind it are slightly askew.
