As an elder of the Americas and of the rest of the planet, it is my responsibility to care for and protect, to the best of my ability, the young. ↗

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic? We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected. ↗

I do not think that there is a reputable scientist on this planet who would advocate using this technology to generate a human child as was just announced. ↗

Public discourse has been polluted now for decades by corporate-funded disinformation - not just with climate change but with a host of health, environmental and societal threats. The implications for the planet are grim. ↗

People from a planet without flowers would think we must be mad with joy the whole time to have such things about us. ↗

I'm a staunch believer that we are in an earth cycle. There's no question the planet is changing, and the fact that the Mayans had an end date and their history talks of change, I find that fascinating. ↗

For me, Batman is the one that can most clearly be taken seriously. He's not from another planet, or filled with radioactive gunk. I mean, Superman is essentially a god, but Batman is more like Hercules: he's a human being, very flawed, and bridges the divide. ↗

You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else. ↗

Most of man's problems upon this planet, in the long history of the race, have been met and solved either partially or as a whole by experiment based on common sense and carried out with courage. ↗

I don't see how I possibly could have come from where I entered the planet to where I am now if there had not been angels along the way. ↗
