Hisense XR10 Smart Projector Review: RGB-Powered Wonder


Pebble has answered its most common customer question โ whatโs the smallest vehicle that can tow the Flow electric travel trailer โ with a MINI Cooper-sized electric pickup.
The company posted photos of TELOโs MT1 electric truck pulling its full-size, 5,800-lb Flow trailer, a pairing made possible by the Flowโs own active propulsion system.
Watering your lawn in the summer can be both pragmatic and fun with so-called "silly sprinklers," designed to create amusing loops and spirals of water jets. And there's some fascinating physics at work to boot. Researchers at New York University's Courant Institute conducted a series of experiments with different silly sprinkler designs to find the answer to a longstanding problem in fluid dynamics, according to a new paper published in the Proceedings of the National Academy of Sciences.
As previously reported, the reverse sprinkler problem is associated with physicist Richard Feynman because he popularized the concept, but it actually dates back to a chapter in Ernst Machโs 1883 textbook The Science of Mechanics (Die Mechanik in Ihrer Entwicklung Historisch-Kritisch Dargerstellt). Machโs thought experiment languished in relative obscurity until a group of Princeton University physicists began debating the issue in the 1940s.
Feynman was a graduate student there at the time and threw himself into the debate with gusto, even devising an experiment in the cyclotron laboratory to test his hypothesis.ย One might intuit that a reverse sprinkler would work just like a regular sprinkler, merely played backward, so to speak. But the physics turns out to be more complicated. โThe answer is perfectly clear at first sight,โ Feynman wrote in Surely Youโre Joking, Mr. Feynman (1985). โThe trouble was, some guy would think it was perfectly clear [that the rotation would be] one way, and another guy would think it was perfectly clear the other way.โ

Today, lepidosaurs -- the reptile group that includes lizards, snakes and New Zealandโs tuatara -- are among the most diverse vertebrates on Earth, but their earliest evolutionary history remains poorly understood.

BYD Energy Storage has landed a contract to supply 11.275 GWh of battery storage for Masdarโs Round the Clock (RTC) project in Abu Dhabi โ one of the single largest energy storage procurements ever signed.
The RTC project pairs a 5.2 GW solar array with a 19 GWh battery system, making it the worldโs largest combined solar-plus-storage plant. BYDโs award covers the majority of that storage.
