Heard a very interesting “ space pen “ story from a seminar, which deserved some deep thinking for our IT guys.
In order for those astronauts to be able to write in the outer space where there is no gravity, US NASA spent millions of dollars inventing a device called “Space Pen”. This look-to-be-normal pen has a very sophisticated device at the other end of the pen that will give constant pressure to the ink such that the ink can come out of the pen even without gravity.
While Americans were so prod of their invention, they were wondering how Russian solved the problem. To their surprised, the Russian astronauts just used a pencil.
