    A boost for quantum reality: the wave function is real!

    Long suspected and hotly debated, the wave function, treated as "merely" a useful mathematical tool since its discovery, has now been conclusively proven to be "real", ie, to accurately reflect the actual reality of how the universe works.

    New exoplanet in habitable zone discovered - 4.5*Earth mass, 22 light years away. Another day, another exoplanet. This one wasn't even by Kepler.

    Gaming O-F iterated prisoner's dillemma tournament - rules finalised, START YOUR AGENTS

    For the uninitiated: I wrote a python script that pits two IPD strategies against each other. Each is aware of its, and its opponent's current score and action history, and must decide whether to defect or...

    Kepler finds "Mars-size" exoplanets I wonder how much longer Kepler will continue to revolutionize our understanding of how solar systems work on a weekly basis. Remember how we used to think our neighbourhood was littered with super-Earths and hot Jupiters?

    Relative vector rotation in cartesian space

    Okay, my vector magic is running low here, some help would be appreciated. I'm trying to rotate a vector in the coordinate origin in Cartesian space with coordinates (x,y,z) by some angle about it's relative y-axis - that is, the axis that points at (0,1,0) when the vector is pointing straight...

    Launch News 神舟八号 (Shenzhou 8 atop CZ-2F, 31st Oct 2011 22:00 UTC)

    Probably only days left until the launch, and there's next to no news about it anywhere. Shenzhou 8 is an unmanned mission which will test automatic rendezvous and docking procedures with the Chinese Tiangong-1 space station module launched in September. China to launch Shenzhou-8 early...

    Rant The hypocrisy of Jobs

    First off, I'd just like to say I've decided not to post this in the other Jobs thread out of respect I have for the man as an innovator. However, I feel this needed to be said. First, thinking in the long term, Steve Jobs claims to be an avowed deathist, claiming death is "the best invention...

    Science f.lux: Prevent your computer monitor from ruining your circadian rhythm

    f.lux I've been experimenting with this for a week now and I'm finding it much easier to fall asleep after using my computer in the evening. There's considerable science behind this.

    Science Mind uploading ("What will computers be like" fork)

    Consider the following scenario: One of your the neurons in your brain is replaced by a nanomachine with the exact same function as the replaced neuron. It's similar enough that your body doesn't even reject it as a foreign object. All of the neural connections and their weights are preserved...

    Generic / planet-specific terms

    In astronomy discussions, which do you prefer? For example, while the generic terms for the orbital apses are "periapsis" and "apoapsis", using planet-specific terms (eg, "Periareion", "Apocynthion", etc) can make a debate much clearer when discussing an interplanetary mission with several...

    Electron-positron annihilation as a propellant

    So, an electron and a positron colliding at low energies (ie, relatively slow, not in a particle accelerator) tend to produce two photons at gamma-ray energy levels (511 keV). Could this reaction be leveraged for spacecraft propulsion? Consider the following, even a miniscule amount of...

    Subjective FTL travel (relativity thread)

    Because the other relativity debates came close to making my head hurt and produced no agreeable conclusion, can a theoretical physicist please clear this up: A starship headed for a star 100 ly distant accelerates up to a velocity of .9c relative to an Earth-based observer. At that velocity...
