Time travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world

Road?  Where we’re going, we don’t need roads. – Dr. Emmett Brown.
Here’s a look back at the maker world and beyond!


Way Back In Time…

1947


The first polaroid camera was shown on February 20th, 1947. Inventor Edwin H. Land showed it off at a meeting of the Optical Society of America in New York.


1896


Henry Grenon, an African American inventor, received American patent number 554,867 on February 18, 1896, for a Razor Stropping Device intended to help travelers carry their razors more safely in a frame to protect the blade.


1201

Born on February 18, 1201, just before the sweeping destruction of the Mongol invasions destroyed Baghdad and the Abbasid Empire, Nasir al-Din al-Tus was a logician, astronomer, philosopher and all around great thinker and helped expand knowledge in every field in which he worked. He discovered the law of tangents for spherical tangents, described an early version of the law of conservation of mass and wrote poetry and about law and ethics.
