Researchers have designed micro-unmanned aerial vehicle inspired by a maple seed. The University of Maryland engineers studied the spiral flight the seeds take when they fall from a tree and created what the university claims is the "world's smallest controllable single-winged rotocraft."
In the 1950s, researchers first tried to create an unmanned aerial vehicle that could mimic a maple seed's spiraling fall. Ever since, their attempts have been foiled by instability, resulting in a lack of control over the tiny (less than one meter) vehicles, which were easily knocked off course by wind.
The Clark School (Aerospace Engineering) students have solved the steering problem and provided a solution that allows the device to take off from the ground and hover, as well as perform controlled flight after its initial fall to the ground after being deployed from an aircraft. The device can also begin to hover during its initial descent, or after being launched by hand.
California assemblyman Jim Cooper (D-9th) has copy-pasted New York assemblyman Matthew Titone’s (D-61st) insane, reality-denying bill that bans companies from selling smartphones with working crypto on them, introducing nearly identical measures in the California legislature.
Trumpscript — a python variant — only allows numbers over 1,000,000; has no import statements (all declarations must be homegrown); only has integers because floating-point numbers are un-American (America never does anything halfway); only allows popular words and the names of politicians as variable names; limits error messages to direct Trump quotes; and requires that […]
“Radical ecology” has come to mean a kind of left-wing back-to-the-landism that throws off consumer culture and mass production for a pastoral low-tech lifestyle. But as the brilliant science journalist and Marxist Leigh Phillips writes in Austerity Ecology & the Collapse-Porn Addicts: A Defence Of Growth, Progress, Industry And Stuff, if the left has a future, it has to reclaim its Promethean commitment to elevating every human being to a condition of luxurious, material abundance and leisure through technological progress.
