Coloured SEM of the nib of a ball point pen
Nib of a ballpoint pen. Coloured scanning electron micrograph (SEM) of the ball at the nib of a ballpoint pen. The ballpoint pen was invented in 1938 by Hungarian journalist Laszlo Biro. It was adopted by the RAF in 1944 to resolve the problems pilots faced in writing when flying at high altitudes. In 1953 Bich,a French baron,developed a process for producing ballpoint pens at a low cost. We now buy three thousand million of them every year.
