It's now clear I'm on a Black Hole binge (I can stop when I want, by the way). They're endlessly fascinating. My recent interest was in particular focused on simulating visualizations of the Schwarzschild geometry. I was preoccupied by the problem of generating a decent accurate representation of how the curvature of…
KAHNEMAN: Could you elaborate on these possibilities? I mean, what's the distinction between predicting and setting up a range of possibilities?
To reject gods and spirits is easy: just bully them away in the name of science.
Even as we discover more about Ceres, some mysteries only deepen. Mission Director Marc Rayman gives an update on Dawn as it moves ever closer to its next…
This text is designed to accompany your study of introductory digital signal processing. 1 It’s an eccentric piece of not-so-rigorous literature with a preoccupation for explaining things using interactive visualizations, animations and sound. 2 My goal is to explain the Discrete Fourier Transform using a miniature…
It’s one of the nearest red supergiants to us, and a supernova is only a matter of time. What are we in for when it happens?

No need for color correction—Harvard physicists’ flat optics, using nanotechnology, gets it right the first time
The original paper that introduced the simulation argument
Graham's number is so big, we need a whole new set of tools to even discuss it.
An-225 Mriya (which is referred to Dream from Ukrainian) is the heaviest airlift cargo aircraft ever taken off in the sky. The maximum takeoff weight makes 640 tons. An-225 was designed, due to the necessity to create the air transport system for the Soviet reusable Space Shuttle Buran. This is the…
As I write this post, New Horizons is nearing the end of a weeklong optical navigation campaign. The last optical navigation images in the weeklong series…
Formal Theory of Creativity & Fun & Intrinsic Motivation (1990-2010) by Jürgen Schmidhuber
Researchers delivered a modified RNA that encodes a telomere-extending protein to cultured human cells. Cell proliferation capacity was dramatically increased, yielding large numbers of cells for study.

Scientists at the Institute of Optics have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings.
The NASA/ESA Hubble Space Telescope has captured the sharpest and biggest image ever taken of the Andromeda galaxy — otherwise known as Messier 31. The enormous image is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s…
