Sextant: data and historical old ship GPS navigation
Continuing from our last post on models of historic civilizations and data, we’re drawing a line from Carl Sagan to the Conquistadors (and modern TV documentaries’ theories about them). This historic photo is an antique sextant from 1890. This historical navigation device worked by measuring the angle between the sun (or stars) and horizon using two mirrors. It was the GPS (or Apple Maps) of its day. And, as we learned from Apple Map’s initial glitches, then as now, successful navigation required a lot of information (or data) to work correctly! Since the Internet didn’t exist, this data had to arrive by some other means, which we’ll talk about in a future post. (So we’re also continuing on our earlier mirror theme.) The use of two mirrors’ reflection to align the image of the object with the horizon (when the sextant was set at the correct angle) enabled accurate measurements when on a moving platform, such as by a sailor on a boat at sea.… Read the restIOT Internet toilet senses disease (and talks?)
We promised to return to Earth after our previous photo post discussing 3,000-year-old Chinese sunspot observations and catastrophic space weather. How else could we do this other than another important Asian trend that we missed: Internet-connected toilets. Don’t laugh, this isn’t a Google April Fools joke (although Google reportedly has installed an earlier non-IOT model of these “advanced” toilets by the same manufacturer, Toto of Japan, in their offices). IOT Internet toilets actually make a lot of sense. These Japanese units from Toto can automatically detect disease via blood glucose, blood pressure, and BMI sensors. They can transmit this health information via WiFi. As they say in startup world, this is obviously a billion dollar idea. All of this can then be integrated with something like Apple’s HealthKit. Thus, they can be integrated with the rest of iOS. So, in the not to distant future, your toilet should be able to talk to you via Apple Siri.… Read the restDolphin with wearable computer?
Finishing up our mirror animal consciousness theme, we promised one last very special animal (or group). This is it. Cetaceans, which includes dolphins, are the last of the currently known very small group of highly intelligent 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 animals out there. This particular leaping bottlenose dolphin is named K-Dog, and has been trained by the in mine-clearing operations by the US Navy. Many people (and some bloggers) erroneously believe chimps are the second smartest animal after humans.… Read the restEbola: Can big data or semantic text help?
“Many problems” in this case Yes it can. We’ll get to to how big data or semantic meaning can help in a moment. First a few observations. As the Prof. Redlener, the NYT’s expert on disaster preparedness put it, “There are many, many problems that have been revealed by this single case.” This is a polite way for saying what at the Dallas hospital was a major screw-up that needlessly put lives in danger and unnecessarily forced additional people into a 21-day quarantine. We can talk about using semantic text technologies to prevent these kinds of hospital errors, or big data to improve traveler screening processes. At the end of the day, however, this is a type of error that the billing department at the Dallas hospital should have been able to catch. EbolaCare(TM) insurance “Where do we send this bill?” “Hmmm, address in Liberia. Looks like he has EbolaCare(TM), the national health plan of Liberia.”… Read the restRecent Posts
