The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage. It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer. The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

William Ferrel was an American meteorologist, developed theories which explained the mid-latitude atmospheric circulation cell in detail. He demonstrated that it is the tendency of rising warm air, as it rotates due to the Coriolis effect, to pull in air from more southerly, warmer regions and transport it poleward. It is this rotation which creates the complex curvatures in the frontal systems separating the cooler Arctic air to the north from the warmer continental tropical air to the south.

Mosaic is the web browser credited with popularizing the World Wide Web. Marc Andreessen is best known as co-author of Mosaic, the first widely used Web browser. He is one of only six inductees in the World Wide Web Hall of Fame announced at the first international conference on the World Wide Web in 1994.
