The Voyager 1 probe is travelling 11 miles per second.

Wednesday is April Fools day. (I wonder what will happen this time...)

Life is so awesome.

The first sans-serif font was created in the mid-1930s, and Times New Roman was released in 1928.

Facebook has around 30,000 servers which must store more than a couple petawatts of data.

Some of Poland's first tanks included the 7TP (7 Tonnes Polish/Siedmiotonowy Polski).

If you were to scoop out a piece of neutron star material from a neutron star's core, the neutron degenracy pressure would be released in a massive explosion, vaporizing everything around it. The next step would be neutron decay, as within the time-span of 10 minutes neutrons decay into neutrinoes, however, if we calculate how much mass is lost in this decay and times it by the speed of light squared, we will get the result that due to this decay another 50 million megatons of energy would be released, enough to destroy the entire Earth instantly.

Because magnetic fields don't pass through superconductors, superconductors can float above magnets.

The Tunguska explosion wielded forces around 30 megatons, some 2000 times more powerful than the Hiroshima bomb and scientists found substancial amounts of fall-out, but because this happened in 1908, there were no nuclear weapons. Scientists today predict it may have been a meteorite and some conspiracy theories claim that Nikola Tesla accidentally fired his death ray there instead of the North Pole.
