Maderization

Maderisation is a process that involves the heating and oxidisation of a wine. The term is named after the process used in the production of Madeira wine, where it occurs while the wine is in cask. The resulting wine darkens in color and acquires a Sherry-like character.

Sounds on frozen lakes


Incredible sound. 

Reminds me of this guy getting excited over the same sound, starts at 3:41



But this is still probably the best example:
Skating on a newly-frozen lake


8 cinematic drone movements


Tilt up reveal
Bird's eye - create symmetry, gives viewer something to decode
Tracking - follow subject through a scene
Crane/jib shot - emulate a crane, lift above eye level, use slow motion
Pullback shot - like a "dronie"
Orbit
Low altitude - dynamic sense of speed with landscape rushing under camera

Arctic Dining: Think Frozen Sashimi - The New York Times

"Fishermen and reindeer herders in northern Siberia have long snacked on raw, frozen fish and meat. Shaved thin and often dipped in sauce, the dish is one of Russia's hidden delicacies."
"It is raw, frozen fish or meat, shaved thin with a sharp knife so that it curls off the blade. Hurry — you have to eat it before it thaws for the best flavor and texture, dipping the frozen shavings into a salt-and-pepper mix or your favorite sauce, then chewing lightly as they melt on your tongue, like a Popsicle version of sashimi or carpaccio."
"Its bracing and freezing rawness, followed by its subtle tenderness, distills the wild, blustery, softly lit grandeur of the Far North."

Driving in snow

Control a skid by steering INTO the direction of the skid: look where you want the car to go, and steer hard that way. You can start watching at 1:29 if you don't have a lot of time. 

For a more detailed look with lots of examples, they illustrate this in more detail in this video at 6:11.  
And in the same video, at 1:52, beware of bridges where the wind cools the road surface from both top and bottom, so it freezes earlier.

Parent's Kiss to remove nasal foreign bodies




Genius. It's such a clever technique because the kid will only cooperate with their own parent putting the straw in, and they will naturally close their glottis when surprised when the parent blows air in, forcing the air out through the nose and expelling the foreign body.

Physicists in China challenge Google’s ‘quantum advantage’ - DNA Zone

The numbers in this report are absolutely mind-blowing. 
"Pan and colleagues could find solutions to the boson-sampling problem in 200 seconds. They estimate these would take 2.5 billion years to calculate on China’s TaihuLight supercomputer — a quantum advantage of around 1014."

Maurice Hilleman arguably saved more lives than any other single person in history.

One single scientist developed over 40 vaccines in his lifetime, including eight of the vaccines that are still routinely given to every child. He's described in this podcast as someone who just had an innate gift for the judgments in a lab when making a vaccine. 
Reflecting on his life, he said, humbly, at 35:40 "I'm kind of pleased about it – I'm not smug. There's a great joy in being useful in life."

Babies prefer to gaze upon beautiful faces | New Scientist




"[Researchers] showed paired images of faces to babies as young a one day old and found that they spent more time fixated on the more attractive face.

"Attractiveness is not in the eye of the beholder, it's innate to a newborn infant," says Slater."

"...[they] took pictures of a variety of female faces and asked adult subjects presented to rate them for attractiveness. Subjects scored each face on a scale from 1 to 5. The researchers then searched for pairs of photographs that were similar in all respects – in brightness and contrast, for example – but at opposite ends of the attractiveness scale.

They then presented these paired photographs to newborn infants, who ranged in age from one to seven days old. All babies were still in hospital after birth. One researcher held each infant upright about 30 centimetres away from the two photos. Another stood out of view and noted where the babies eyes were directed."

SPAC investments

"Special purpose acquisition companies" are shell companies offering venture capital as a quick shortcut to raising capital without the paperwork of an IPO. A spate of them recently NKLA, DKNG,. UTZ has made them popular. 
This article offers these caveats to consider:
"
  • Is the target business established and generating cash flow?
  • If not, does it have a viable strategy and is it positioned to achieve its goals?
  • Will the company need to make major investments in technology, talent or other resources to succeed?
  • How accomplished is the management team, and are they staying with the company after its acquisition by the SPAC?
  • Does the target company have a durable, competitive advantage, such as a patent or cutting edge technology, that gives them "a wide and long-lasting moat," to quote from Warren Buffet's most important factor when evaluating an investment?
  • What are the target's biggest risks factors? "

The Sailboat Designed to Fly

Pretty amazing sailboat design. Huge weight saving by eliminating a keel and instead having an outboard hydraulic hydrofoil generating force like a buttress holding the sailboat from heeling (heeling is lateral roll or tilt caused by force of wind on the sail versus drag of the hull in the water)

You can start at 2:19 in this video for an explanation of the "canting T-foils" that buttress the boat from the leeward side. 

And you can start at 1:46 in this video for an analysis of hull design, with the lift created by the upper surface of the deck described at 5:03.

This American Life: The Feather Heist


An intriguing and surprising story that takes you on a journey you'd never expect. 

Pandemic effects on society

Just as I thought. Police are worried about catching COVID from traffic stops, so policing decreases and people are feeling free to speed more. 
"The rate of crash deaths in the U.S. rose as the coronavirus pandemic erupted this spring, fueled by an increase in risky behaviors like speeding and by a reduced police presence on roadways"



What about STDs? I thought maybe people are isolating and not interacting with others as much...but that's outweighed by individual's reluctance to get tested (for fear of getting COVID) which fuels rampant spread from unabated sexual activity despite the pandemic, combined with a hampered ability to trace their contacts. 

STD rates appear to be quietly skyrocketing across the US, as fewer people get tested and treated during the pandemic.

"Flash" graphene made from plastic waste

Sounds like a win-win: 
"at industrial scale, the process could produce graphene for about $125 in electricity costs per ton of plastic waste..."
"Rather than recycling plastic into pellets that sell for $2,000 a ton, you could be upcycling to graphene, which has a much higher value..."
"We produce considerable amount of hydrogen, which is a clean fuel, in our flashing [production]  process..."
"The nice thing about graphene is its biological degradation under many conditions is very slow, so in most cases it doesn't reenter the carbon cycle for hundreds of years..."

Debussy himself plays Clair de Lune (1913)

I've always wondered this. Did Debussy want Claire de Lune played by taking liberties with the time? 

He was inspired by the impressionist painters, and, as I suspected, wants the dappled random points of light in impressionist works to infuse this piece with a random, joyful, sparkling of notes in the upper register. And, the bass is more subtle than most people play it. We are so constrained with the rigidity of many classical composers that people don't feel comfortable talking liberties with the time signature when playing this piece. Wonderful. 

At 0:34, and again at 0:54, the melody arrives at a significant bass note, and most pianists emphasize that note like the "drop" in a pop song. He artfully makes that note quite subtle, again emphasizing the random playful upper notes. 

What follows after 0:54 is usually played quite regularly and rhythmically, but he has this lovely, random cascading saltatory progression through the chords, like he's pausing to smell the roses when there's a particularly nice chord. Beautiful.

And here's a lovely rendition by Victor Borge:

And, of course, have to include that classic Victor Borge hilarious bit about spoken punctuation:

Realistic Water Bubble Simulation


At 2:30, he marvels that adding realistic air - water interaction requires such a simple calculation: "...one unified technique to add foam, spray and bubbles..." 
3:49 " ...bubbles and foam appear at the regions where air gets trapped beneath the surface...at wave crests...by looking for regions where the curvature of local fluid geometry is high and locally complex" 

This simplification allows the bubble effect to be added or taken away in post-processing, meaning that after 40 hours of rendering, the bubbles can be added or subtracted without having to render the entire simulation again. He illustrated this at 3:14

Here's his subsequent video on bubbles simulation.

Police have no special duty to protect - Radiolab

This podcast is an intriguing and rather sobering  investigation into the landmark cases that have defined what the police must do. It turns out, in order to broadly protect us all from living in a police state with severe punishment for everything, surprisingly, the police have no duty to protect you from imminent harm. Unless four (almost never true) conditions are met - you ask them to help, they perceive the threat is real, they agree to help, and you change your behavior as a result of knowing that they will help. 

It's also an extension of the fact that citizens are not legally required to help someone in need when they're passing by - it might be heroic or morally right to help them, but not legally in that you wouldn't have to cover their damages. 

As they explain, certain people have a "special relationship" with you so that they are legally bound to protect you - like a hotel owner, a transit organization when you're their passenger, or a cab driver. So they're legally bound. 

So in the contemporary angst about what the "police role" is and whether we should fund them, there isn't any fundamental specific guide or charter describing what they're legally bound to d. This surprising absence is distinctly different than the entire rest of the government like the FDA, FAA and so on.
