"Think binary. When matter meets antimatter, both vanish, into pure energy. But both existed; I mean, there was a condition we'll call 'existence.' Think of one and minus one. Together they add up to zero, nothing, nada, niente, right? Picture them together, then picture them separating--peeling apart. ... Now you have something, you have two somethings, where once you had nothing." -John Updike Looking out at our Universe, at the myriad of stars, galaxies, and, well, &q...

"One of the great things about music is that it has the capability of time travel - you smell a certain smell in the room and it takes you back to your childhood. I feel like music is able to do that, and it happens to me all the time." -M. Ward

"The size of the universe is no more depressing than the size of a cow." -David Deutsch But it is bizarre, I'll give you that. The most common scientific question I get asked is how, if the Universe is 13.7 billion years old, and the speed limit of the Universe is the speed of light, why do I say the observable Universe is 93 billion light years across?

Research done at Cornell has uncovered the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and other big questions in astrophysics.

“Do you know where to find marble conference tables? I'm looking to have a conference... not until I get the table though” -@kanyewest on Twitter

This is a note on, the Turing Award laureate, Ted Codd's revolutionary paper — A Relational Model of Data for Large Shared Data Banks. In this post, I will review the paper and add my comments with a perspective from modern distributed databases. Tight couplingHow users used to interact with databases

"We now have the best picture of how galaxies like our own formed their stars." -Casey Papovich The expanding Universe is counterintuitive in a lot of ways: on the largest scales, the distances between galaxies are increasing at an alarming rate, yet the distances between the stars in our own galaxies or the atoms in our bodies don’t appear to change. It makes one wonder whether there’s a size limit to how small a piece of the Universe can be and still expand?

“Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation.” -Edwin Hubble We really got into some wondrous stuff here at Starts With A Bang this past week, including:

“Faultily faultless, icily regular, splendidly null, dead perfection; no more” -Lord Alfred Tennyson Ahh, the Standard Model of elementary particles and their interactions. It's right up there with General Relativity -- our theory of gravitation in the Universe -- as the most successful physical theory of all-time.
