Dolphin with wearable computer? (photo blog)
Finishing up our mirror theme, we promised one last very special animal (or animal group) that is the last of the currently known animals that can recognize themselves in a mirror. (All of the others are mammals, with the exception of magpies. We started off with extinct mammoths, who are closely related to elephants, then went through magpies and great apes, with a lot of mirror photos along the way.) The actual animal that passed the mirror test is the bottlenose dolphin (shown here), but it is believed all cetaceans can pass the test. Cetaceans include dolphins, whales, and porpoises, known to be some of the most intelligent animals out there. This particular leaping bottlenose dolphin is named K-Dog, and has been trained by the US Navy in mine-clearing operations. He’s wearing what looks like a camera, but is described as a locator beacon (and probably includes a camera and other aspects of a wearable computer.)… Read the restElectronic silicon wafers & Chinese magic mirrors (Photo)
Almost wrapping up our mirror theme, we wanted to point out one important application of mirrors in the manufacture of silicon wafers for electronics. Chinese magic mirrors go back to the Han dynasty in China (206 BC — 24 AD). Called “Makyoh” in Japanese, they are a traditional art form in Japan, requiring great skill to manufacture by hand. The manufacture involves first engraving image (intended to be hidden) on a metal surface. This image is then sanded down so that the image is no visible to the naked eye, with the metal now appearing smooth. A mercury amalgam is then poured over to create a mirror surface. The mirror appears to be a normal mirror. However, when exposed to bright light, it projects the hidden image onto a wall. This was used by the “Kakure Kirishitan” (“Hidden Christians”) in Japan to allow the temporary projection of secret images onto walls (e.g.,… Read the restRecent Posts
