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!


Lucite, more commonly known today as plexiglass, began commercial production seventy-seven years ago today at a Dupont chemical plant.



Williamina Fleming, part of Edward Pickering’s infamous “harem,” (really a group of women who performed calculations for his research) was the first to identify “white dwarves” and died 102 years ago today.  Starting out as a maid at Pickering’s house, she gradually moved up to clerk, then to performing mathematical calculations for his work, and finally conducting research in her own right.  She also notably discovered the Horsehead Nebula in 1888.


In 1819 the first bicycle was seen on the street of New York City. Officials were quick to ban these dangerous “velocipedes” from “public places and on the sidewalks of the city.”
