“By refocusing our space program on Mars for America’s future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it’s time for us to live and work on Mars, first on its moons and then on its surface.”…

“Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. We kick reality and feel it kick back. From the intensity and duration of thousands of those kicks over many years, we have formed a coherent theory of matter and forces, called the standard model, that…

I may not blog as much as I used to, but I do still sometimes put myself out there. I just did a podcast with Jim Stein, posted over at the New Books Network. Jim is professor of mathematics at California State University at Long Beach. The conversation was about the book I coedited with…

“Love doesn’t make the world go ’round. Love is what makes the ride worthwhile.” -Franklin P. Jones It’s been such a busy time here at Starts With A Bang that we’re a day late bringing you last week’s recap! And we’ve got to get rocking on it, because there’s so much coming up to consider as well!…

“The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.” -Richard Feynman One of the strangest, most novel predictions of Einstein’s relativity is that mass would not only curve space, but…

I’ve had this piece by Rick Borchelt on “science literacy” and this one by Paige Brown Jarreau on “echo chambers” open in tabs for… months. I keep them around because I have thoughts on the general subject, but I keep not writing them up because I suspect that what I want to say won’t be…

“When you get just a complete sense of blackness or void ahead of you, that somehow the future looks an impossible place to be, and the direction you are going seems to have no purpose, there is this word despair which is a very awful thing to feel.” -Stephen Fry Perhaps the most fundamental difference…

A whole bunch of physics posts over at Forbes so far this month: —Recent Physics Books: Gravitational Waves and Brief Lessons: Short reviews of Janna Levin’s Black Hole Blues and Carlo Rovelli’s Seven Brief Lessons on Physics. —The Real Reasons Quantum Entanglement Doesn’t Allow Faster-Than-Light Communication: Expanding on and correcting some stuff I didn’t like…

“To explain all nature is too difficult a task for any one man or even for any one age. ‘Tis much better to do a little with certainty & leave the rest for others that come after you.” -Isaac Newton Perhaps the greatest, most successful scientific theory of the past century is Einstein’s General Relativity,…

“We’ve known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make…
