engineeringhistory:

Page from Nikola Tesla’s application for Fellow of the American Institute of Electrical Engineers (AIEE), 1916, the organization’s highest membership grade. When applying for a Fellow, one had to be personally recommended by other AIEE Fellows. On this page, Paul Lincoln, AIEE President from 1914 to 1915 and long time Westinghouse employee writes of his friend “His work on polyphase alternating current is known and recognized the world over as original work of the highest order.”

engineeringhistory:

Front page of a Latin edition of Ibn al-Haytham’s Thesaurus opticus (Book of Optics), written around 1000. The book was a foundational text in the field of optics and this illustration depicts the siege of Syracuse (214 - 212 BC) in which Greek engineer Archimedes was purported to have constructed a series of parabolic mirrors reflecting the sun’s heat onto the besieging Roman ships, catching them on fire.

Urgent security update

support:

Bad news: A major vulnerability has been disclosed for the technology that powers encryption across the majority of the internet. That includes Tumblr. Our team took immediate action to fix the issue, but you should still take some time to change your password, not only here but on any other sites you visit. 

You should also strongly consider enabling two-factor authentication. It’ll go a long way to ensure that no one besides you can access your account. Thanks, and take care.
