“We make the world we live in and shape our own environment.” -Orison Swett Marden If you had never heard of global warming before, how would you figure out whether it’s real or not? And if it is real, how would you figure out what humanity’s role in it is? To answer this, I’ve decided to…

“There is no question that climate change is happening; the only arguable point is what part humans are playing in it.” -David Attenborough It’s been a long time since I’ve written anything on this blog about global warming, climate change, or most Earth-based environmental topics in general. After all, I’m a physicist — an astrophysicist…

“Next to reasoning, the greatest handicap to the optimum development of Man lies in the fact that this planet is just barely habitable. Its minimum temperatures are too low, and its maximum temperatures too high. Its day is not long enough, and its night is too long… These factors encourage depression, fear, war, and lack…

“What was most significant about the lunar voyage was not that men set foot on the Moon, but that they set eye on the Earth.” -Norman Cousins What would life on Earth be like without the Moon? Our nearest neighboring body in the cosmos has a profound effect on us. It’s helped not only shape…

The Rarest Eclipse of Them All

“You can’t exactly bake a man to your specifications… A hybrid of Einstein, Tarzan and Inge Meysel doesn’t exist.” -Peer Steinbruck Of course, if you create enough chances, all the things that could eventually happen will come to pass.

Because it’s during those scary moments, those unsure steps taken, that I am able to see that I’m like a comet hitting a new atmosphere: suddenly I illuminate magnificently and fire dusts begin…

“To disagree leads to study, to study leads to understanding, to understand is to appreciate, to appreciate is to love. So maybe I’ll end up loving your theory.” -John Wheeler Out there in the Universe, there’s a lot to marvel at. Over billions of years, gravity has attracted different portions of the expanding Universe together…

“…because today, with cameras as pervasive as they are, there is no such thing really as professional photographers.” -Marissa Meyer Before you get irate, I don’t actually agree at all with that quote above; I have no talent for photography at all and a tremendous respect for those who do, and who cultivate it to produce something…

The Far Future of our Solar System

“No valid plans for the future can be made by those who have no capacity for living now.” -Alan Watts “They do not see what lies ahead, when Sun has faded and Moon is dead.” -J.R.R. Tolkien One of the most amazing facts about the Universe is that, despite only having spent a few hundred years…

Missions to Mars and Nuclear Fusion

“We are much closer today to being able to send humans to Mars than we were to being able to send men to the moon in 1961, and we were there eight years later. Given the will, we could have humans on Mars within a decade.” -Robert Zubrin Of all the planets in the Solar…
