Real World Turbulence Is So Difficult To Understand Even Quantum Turbulence Is Simpler To Model
Turbulence is part of the cultural lexicon. For casual situations where there are short-term challenges that just require some managing, people often say they are experiencing turbulence. Anyone who has taken a few plane trips has experienced the bumpy ride caused by turbulence in the air.A new technique for studying turbulence in quantum fluids used a mechanical resonator, a miniscule bar 1/1000th the width of a human hair, in superfluid helium near absolute zero temperature to effectively 'trap' a single vortex for study.
Chemicals To Put Out Fires Are ‘Riskier’ For Firefighters Than Actual Fires? Not According To Science
A new paper uses emotional verbiage like "forever chemicals" and sketchy correlation to try and claim that fires are not what firefighters should be worried about when the alarm rings, it's the chemicals created by Evil Corporations they should fear.Firefighters are going to be enraged if they see it, and they should be. It puts their lives at risk. This is not junk science, it isn't science at all.
Did Science Just Create The Perfect Lullaby?
Getting kids to go to sleep has long been a challenge for some, and there are beliefs that it got more challenging during the COVID-19 pandemic.Spotify got science and music together (the parts that aren't already together, music is applied math) to create what they are calling the perfect lullaby. Maybe it will help.
Swedish rappers Jaqueline “Mapei” Cummings and Jason “Timbuktu” are both parents of young children. After Jaqueline gave birth they went to the studio armed with the science of what sounds to use to create the most soothing lullaby according to sleep expert Helena Kubicek Boye. Then they released the work on Spotify Kids.
60 Years Ago Today Alan Shepard Became The First American In Space – Where Will We Be In 60 More Years?
Today is May 5th, when modern Americans assuming this is the day of Mexican independence (it isn't) consume Mexican stuff like burritos and margaritas (those aren't Mexican) but what we should be celebrating is Mercury astronaut Alan Shepard going into space.On this day in 1961, 60 years ago, Alan Shepard let himself be strapped into a capsule sitting on top of a skyscraper of rocket fuel using parts all selected because they were the lowest bidder on a government contract - and set off for the unknown.
Seriously, this was a risk only test pilots would happily have taken. If you look at the spec that NASA gave to all the corporations that actually put us into space, it reads like aspirational quotes more than engineering:

Latte Nonsense: No, Your Genes Do Not Tell You How Much Coffee To Drink
When 23andMe was in its most ridiculous phase of existence, the co-founder was telling FDA to talk to the hand while she assumed campaign donations to members of Congress would exempt them from being told to stop lying about their tests allowing consumers to “take steps toward mitigating serious diseases” like breast cancer.Feel Heavy? There Are 10,000,000 Pounds Of Space Dust Falling On Us Each Year
About 23,000,000 years ago, something hit the giant Asteroid 4 Vesta(1) some 120,000,000 miles away and the impact sent huge rocks into space. In 2018, one such meteorite from that time hit Botswana.It was not unique. Over 30 percent of such Howardite-Eucrite-Diogenites (HED) meteorites that hit Earth year come from just the impact that formed the Antonia crater on Vesta. And then there is everything else happening outside our atmosphere piling on.
6-Foot Rule Does Little To Prevent COVID-19 Exposure
There were a lot of rules introduced during the COVID-19 pandemic that originated during late 2019 in Wuhan, China. Some were pretty Draconian. China welded the homes of people shut and destroyed 16,000 coronavirus samples at the world's largest coronavirus lab nearby. Some were pointless, like everyone carrying Clorox wipes around. Most were less intrusive and at least somewhat helpful; wear a mask, stay six feet apart.Should The Biden Administration Ban Menthol Cigarettes To Protect Black Americans?
Unidentified sources made their way into the Wall Street Journal a short while ago and by stating that the Biden administration was going to ban menthol cigarettes the article caused tobacco stocks to plummet.FDA has until the end of the month to do what the President wants, it was said.It's entirely believable but what is interesting is the new reason for the ban; the government has pivoted from claiming menthol cigarettes "target" people of color to instead claiming they are used by children.
Uncanny Valley: A Webcam That Looks Like A Human Eye
Are you being monitored all of the time? You certainly are, by both corporations and the government. It just may not be obvious in the U.S., whereas in London you are filmed by government 300 times each day, and that concerns privacy advocates.What if the spying were more obvious? Like a webcam that looks like human eye?
