This day is a great celebration for those who have to write at high altitudes in the course of their work. Until this fateful day, all those who took to the air had to accept the fact that either they would have to write with a pencil or get smeared up to their ears with ink squeezed out of “eternal nibs” by internal pressure. Laszlo Biro came up with a way to save the day: he replaced the old-fashioned goose nib at the tip of the pen with a micro ball. So not only we are in debt before the Hungarian inventors for the Icarus and Rubik’s Cube, but also for the ability to write even upside down.
