1675 – Gottfreid Leibniz wrote the integral sign in an unpublished manuscript. It’s a sign that would later haunt the nightmares of students and be widely misapplied on blackboards in movies. So happy Integral Day!

1878 – Willgodt T. Odhner Was Granted a Patent for a Calculating Machine That Performed Multiplications by Repeated Addition

           The patent, a modified and compact version of Gottfried von Leibniz’s stepped wheel, was acquired and embodied in Brunsviga calculators that sold into the 1950s.

1969 – The first ever computer to computer link was established on the ARPANET. UCLA student Charley Kline sent the character l and o to Stanford. The connection crashed before he could finish sending ‘login’. The Internet has been crashy right from the start.

1988 – Sega launched the Mega Drive console in Japan. It would be released elsewhere in the world later as the ‘Genesis.’

2012 – Apple announced Scott Forstall would leave the company in one year, and that retail head John Browett had left the company as well.

2013 – William Lowe, Invertors of the IBM PC Passes

             If you grew up in the 80’s, you knew what an IBM PC was. Even in the 90’s and 00’s, the PC was what you had in the corner of the house to do homework on, surf the internet, work out expenses and more. William C. Lowe was the man that brought that all together. He joined IBM in 1962 and left in 1991. It was in 1981 that the IBM PC debuted.

2013 – Motorola announced its modular phone project called Project ARA. It would end up becoming Google’s project after Google sold Motorola.
