UBI Plans

most of them fail on basic math – they rely on funding schemes that wouldn’t come close to covering costs. The rest are too small to actually lift people out of poverty. None of them are at all credible. These plans fail even though they cheat and give themselves dictatorial power. “End corporate welfare, then redirect the money to UBI!” But if it was that easy to end corporate welfare, wouldn’t people have done it already, for non-UBI related reasons? “We’ll get a UBI by ending corporate welfare” is an outrageous claim. And even the plans that let themselves make it fail on basic math.

Space Radar

Capella’s high revisit x-band constellation with InSAR capability will capture millimeter-scale change’s on the Earth’s surface. Interferometric synthetic aperture radar is a radar technique used in geodesy and remote sensing. This geodetic method uses 2 or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite or aircraft. The technique can potentially measure millimeter-scale changes in deformation over spans of days to years. It has applications for geophysical monitoring of natural hazards, for example earthquakes, volcanoes and landslides, and in structural engineering, in particular monitoring of subsidence and structural stability.

Thought Transparent World

China, India, Iran, Russia, Japan, USA and European nations are actively working to improve existing electroencephalography, magnetic resonance, functional infrared, and the magnetic encephalography spectrums to develop future military applications. The US Air Force believes BCI interfaces could provide faster reaction times for firing missiles, drones and guns.

5x heat exchangers

Possible 5X improvement in heat exchangers

Researchers have discovered a simple way to give a major boost to turbulent heat exchange, a method of heat transport widely used in heating, ventilation and air conditioning (HVAC) systems. In a paper published in Nature Communications, the researchers show that adding a readily available organic solvent to common water-based turbulent heat exchange systems can boost their capacity to move heat by 500%

DIY Phone Farmers

D’Alesandro’s $2000 a month revenue high didn’t last. In 2018, there was a “very sharp downfall”. Advertisers started to crack down. “I think the people putting money into it weren’t exactly sure how it was being used,” he added. In December, D’Alesandro posted his last video to YouTube. In the video description he wrote, “It’s been a great ride, but I feel I need to quit now and focus on other things to grow as a person.” Other farmers have felt the dip too. Goat_City, the farmer who had over 100 phones, is only making around $10 a day now. CallMeDonCheadle took a break after the profits over the past couple of years decreased dramatically. “It has a lot to do with it being less passive and admittedly I can sympathize now that I have a job. Not everyone wants to spend their free time clicking at screens to make fractions of pennies every hour, especially if they have families, friends, and living life in general to attend to.”

Universal Scaling

And this scrambling process happens very early indeed. In their papers this spring, Berges, Gasenzer and their collaborators independently described prescaling for the first time, a period before universal scaling that their papers predicted for nuclear collisions and ultracold atoms, respectively. Prescaling suggests that when a system first evolves from its initial, far-from-equilibrium condition, scaling exponents don’t yet perfectly describe it. The system retains some of its previous structure — remnants of its initial configuration. But as prescaling progresses, the system assumes a more universal form in space and time, essentially obscuring irrelevant information about its own past. If this idea is borne out by future experiments, prescaling may be the nocking of time’s arrow onto the bowstring.

Base rate fallacy

The flawed reasoning behind the Replication Crisis

Medical students are now routinely taught the diagnostic importance of base incidence rates. Bayes’ theorem helps them properly contextualize test results and avoid unnecessarily alarming patients who test positive for something rare. To leave out that final ingredient, the Bayesian prior probability, would be to commit a fallacy of the same species as the one in the Sally Clark case. The crisis of replication has exposed the fact, which has been the shameful secret of statistics for decades now, that the same fallacy is at the heart of modern scientific practice.
