A play on Mr. Lovenstein’s original by Dorsa Amir.…

And why it was very silly of me to think of them as mere adornments: The larger fur liner creates a larger boundary layer [a thin layer of air created by molecules bumping into each other]. (Cached: fur, no fur)…

Forget where I saw this illustration but I love it and had a lovely time drawing some versions of it myself, experimenting with various shadings. It’s from a book called Géologie by Marcel Oria, published by Hatier press in 1958. This is what its cover looks like.…

I have never given Jeff Bezos a moment’s thought before this week. I am always interested in extraordinary achievement and often admire it. I am fascinated by what extraordinary achievers understand, and how evolved they are as people. Looking at him in his astronaut costume, and his cowboy hat, a…

It’s hosted by three University of Iowa engineers and scientists who are tired of “cropaganda” and is rather entertaining. The latest episode calls the recent E15 Law a “Fart in a Hurricane”. One of the hosts is an engineer named Chris Jones who also writes a very lively blog with wonderful nugget…

I can’t see a thing on the surface of Venus. Why not? Because it’s covered with a dense layer of clouds. Well, what are clouds made of? Water, of course. Therefore, Venus must have an awful lot of water on it. Therefore, the surface must be wet. Well, if the surface is wet, it’s probably a swamp.…

A study of DNA extracted from the leg bones of extinct moa birds in New Zealand found that the half-life of DNA is 521 years. So every 1,000 years, 75 per cent of the genetic information is lost. After 6.8 million years, every single base pair is gone. Bacterial RNA is much tougher and sequences h…

This is the Schmidt Sting Pain Index, an eponymous and subjective measurement of the pain caused by bees, wasps, and ants (and other things in the order hymenoptera.) It ranges from 0-4. In Level Zero, you don’t feel any pain whatsoever; the stinger doesn’t even penetrate your skin. The humble and…

In college, I remember being blown away by a huge, physical map of metabolic pathways our Biochemistry professor once brought into class. It looked like this: Here it is online. Kinda like a Google Maps of cellular reactions. It was impressed upon us that the interior of a cell (especially a euk…

Note that you can certainly burn them. That’s not ‘cooking’, however. The key here is that mushroom cell walls are composed of chitin which is far more heat-stable by virtue of the structures it forms, compared to pectin which is what you’d find in veggies1. In this video, Dan Souza explains all t…

Nakamuro and his team looked at the videos Sakakibara had captured and were the first people ever to see tiny cuboid crystals made of tens of molecules of NaCl emerging from the chaotic mixture of separate sodium and chloride ions. Straight away, they noticed a statistic…

It was found in 1982 in France. It’s 165M years old. Researchers reconstructed it in 3D using “synchrotron microtomography.” I was unable this reconstruction because the system of scientific journals is a money-grubbing bullshit system run by greedy people. Here she is though ♥️…

By the Audubon Society cached. Ravens are beefier, gauche, and less ‘refined’. They’re also relatively solitary. They have curvier beaks, wedge-like tails, and soar instead of flap. Here’s what a raven and a crow sound like.…

Here’s the full graphic. Watch anything by PBS SpaceTime on the subject 💯…

Was looking for a portable iPhone microscope and came by this one on Amazon. Doubted the “50x-1000x magnification” claim and landed on this video by Oliver Kim (here’s his channel on YouTube) on how to make sense of that feature. https://www.youtube.com/watch?v=Whvviay3fu4 The key idea here is to…

👉 Of all the stuff I could’ve attempted to appreciate from the genius’ collegiate notebook, I loved these annotations the most and don’t care what that says about me.…

Look we just wanted to make sure The Ocean would remember our species for having delivered value at any cost.…

One of my favorite things in the world. Located southwest of Orion in the southern-hemisphere constellation Fornax, the rectangular image is 2.4 arcminutes to an edge, or 3.4 arcminutes diagonally. This is approximately one tenth of the angular diameter of a full moon viewed from Earth (which is…

https://www.youtube.com/watch?v=-AdW030xQB4 TL;DW: This is “anti-fouling” that repels barnacles, algae, and mollusks by emitting “biocides”. This is desirable because they cause drag (think fuel) and structural damage. Red because traditionally some oxide of Copper. Also this: In nature bright…

Stumbled upon this nearly three-hour, real-time, annotated simulation of the Titanic sinking. Late night1. Which led me to James Cameron’s 2012 documentary Titanic: The Final Word, in which he assembles a group of engineers and historians to fix the simulation in the 1997 movie, which leads to thi…

This video of a ball swinging in front of concave mirror (starts at 2:00, cannot embed for some reason) reminded me of simulations of what it would be like if one fell into a Black Hole. Here’s a Schwarzschild Black Hole, one “with mass, but with no electric charge, and no spin.” (Source) https:/…

Best thing I’ve seen this year. About as spiritual as it gets. https://www.youtube.com/watch?v=uD4izuDMUQA After an unimaginable length of time, even the black holes will have evaporated and the universe will be nothing but a sea of photons, gradually tending towards the same temperature, as the…

NPR on why many of us can identify with little Agnes: https://www.youtube.com/watch?v=1SI6rhotAkE The study found that for the entire group of participants, cuter creatures were associated with greater activity in brain areas involved in emotion. But the more cute aggression a person felt, the m…

Minute Physics on how Muons reaching terrestrial detectors from the upper atmosphere are direct proof of time dilation/length contraction in Special Relativity. https://www.youtube.com/watch?v=rVzDP8SMhPo What a Boss 🙏 💯…

The 1.25s interval between each ‘tick’ in the background score of the water planet scenes1 in “Interstellar” indicates the passage of a single day on Earth. #theydidthemath See also: thalassophobia↩︎…

When we arrived we were introduced to Henry Bethe, who is now five years old, but he was not at all impressed. The only thing he would say was “I want Dick. You told me Dick was coming,” and finally he had to be sent off to bed, since Dick (alias Feynman) did not materialise. About half an hour la…
