‘Letterlocked’ Trove: X-Rays to Peer into Sealed 17th-Century Notes

November 20, 2015 by www.livescience.com Leave a Comment

For years, Jana Dambrogio, a conservator at MIT, has been studying the elaborate ways people used to fold and seal their letters to keep busybodies and spies from reading their secrets. The way a paleontologist analyzes fossils to reconstruct extinct creatures, Dambrogio looks at the blobs of wax and the folding patterns on flat, already-opened letters in manuscript collections so that she can reverse-engineer "letterlocking" techniques. She had never held a historical, unopened locked letter in her hand until she got a call from her colleague, Daniel Starza Smith, at the University of Oxford. "He asked me, 'What would you do if I told you there was a trunk with 600 unopened letters?'"Dambrogio said. "He had me at 'unopened.'" [ See photos of the treasure trove of sealed 17th-century letters ] That trunk, which belonged to a 17th-century postmaster, had been sitting undisturbed in The Hague's Museum voor Communicatie since 1926. It was recently rediscovered and … [Read more...] about ‘Letterlocked’ Trove: X-Rays to Peer into Sealed 17th-Century Notes

Squid skin inspires novel “liquid windows” for greater energy savings

February 2, 2023 by arstechnica.com Leave a Comment

Squid and several other cephalopods can rapidly shift the colors in their skin, thanks to that skin's unique structure. Engineers at the University of Toronto have drawn inspiration from the squid to create a prototype for "liquid windows" that can shift the wavelength, intensity, and distribution of light transmitted through those windows, thereby saving substantially on energy costs. They described their work in a new paper published in the Proceedings of the National Academy of Sciences. “Buildings use a ton of energy to heat, cool, and illuminate the spaces inside them,” said co-author Raphael Kay . “If we can strategically control the amount, type, and direction of solar energy that enters our buildings, we can massively reduce the amount of work that we ask heaters, coolers, and lights to do.” Kay likes to think of buildings as living organisms that also have "skin," i.e., an outer layer of exterior facades and windows. But these features are largely static, limiting how … [Read more...] about Squid skin inspires novel “liquid windows” for greater energy savings

Blue State Blues: My African-American Education

February 3, 2023 by www.breitbart.com Leave a Comment

Florida Governor Ron DeSantis (R) stirred controversy last month when he objected to the contents of the College Board’s new Advanced Placement (AP) course on African-American Studies. Florida law prohibits radical philosophies like Critical Race Theory, which describes America as fundamentally racist, from being taught to children. So he was well within his rights — and seems to have encouraged some improvements . For his trouble, DeSantis has been smeared as a racist and a fascist who is opposed to the teaching of black history — as if “black history” must be whatever the left decides it is. This week, the College Board released its current framework for the AP course — which does include radical ideas such as “intersectionality,” which holds that black people must back other “oppressed” groups, even when doing so is against their own interests. However, the AP framework also includes material on “black conservatives,” which is encouraging (provided their ideas are … [Read more...] about Blue State Blues: My African-American Education
