The shuttle program ends, and with it, an era of American tech excellence

The last American space shuttle, STS-135, lifted off this morning, bringing to a close a remarkable era in U.S. technological dominance. I stayed home and watched the launch on TV, just as I watched the very first shuttle launch on TV in 1981. Both events were deeply tied into the computer era. In 1981, I […]

May 25, 1945: Sci-Fi Author Predicts Future by Inventing It

1945: Arthur C. Clarke begins privately circulating copies of a paper that proposes using space satellites for global communications. It was a bold suggestion for 1945, as the war was just winding down and most people were undoubtedly more concerned about the necessities of life than they were with beaming radio waves down from space. […]

How a Legacy From the 1800s Is Making Tokyo Dark Today

A strange legacy of the Japanese power system’s infancy in the late 1800s is complicating efforts to keep Tokyo supplied with electricity. The problem, as explained by IDG News Service’s Martyn Williams, is that half of the country uses power whose current alternates at 60 Hz, while the other half gets its power at 50 Hz. […]

Nov. 2, 1815: Boole Born, Boolean Logic Logically Follows

1815: English mathematician George Boole, who would help establish what is now known as Boolean logic, is born. Boole’s breakthrough was the insight that logic, which had previously been considered a branch of philosophy, was actually closer to mathematics. All you needed to do was express logical problems in a symbolic format, and they could […]

October 7, 1954: IBM Gets Transistorized | This Day In Tech | Wired.com

1954: IBM builds the first calculating machine to use solid-state transistors instead of vacuum tubes. IBM already had a business selling calculating machines, and it was humming along quite nicely. The IBM 604 Electronic Calculating Punch, which IBM introduced in 1948, was a desk-sized cabinet that ate and spat out punch cards in its single-minded […]

Feb. 25, 1837: Davenport Electric Motor Gets Plugged In | This Day In Tech | Wired.com

1837: The U.S. Patent Office approves Thomas Davenport’s application for a patent on an “Improvement in Propelling Machinery by Magnetism and Electro-Magnetism.” We’d call it an electric motor. Davenport was a Vermont blacksmith and an amateur tinkerer, not a trained scientist or engineer. When he heard about a machine that used an electromagnet to separate […]
