In a Memorial Day reflection, historian Heather Cox Richardson highlights a pamphlet distributed by the US War Department to Army soldiers during World War II on the topic of fascism: what it is and how to combat it.
The War Department thought it was important for Americans to understand the tactics fascists would use to take power in the United States. They would try to gain power "under the guise of 'super-patriotism' and 'super-Americanism.'" And they would use three techniques:
First, they would pit religious, racial, and economic groups against one another to break down national unity. Part of that effort to divide and conquer would be a "well-planned 'hate campaign' against minority races, religions, and other groups."
Second, they would deny any need for international cooperation, because that would fly in the face of their insistence that their supporters were better than everyone else. "In place of international cooperation, the fascists seek to substitute a perverted sort of ultra-nationalism which tells their people that they are the only people in the world who count. With this goes hatred and suspicion toward the people of all other nations."
Third, fascists would insist that "the world has but two choices — either fascism or communism, and they label as 'communists' everyone who refuses to support them."
It is "vitally important" to learn to spot native fascists, the government said, "even though they adopt names and slogans with popular appeal, drape themselves with the American flag, and attempt to carry out their program in the name of the democracy they are trying to destroy."

The Inouye Solar Telescope is the largest and most powerful solar telescope in the world. The telescope is still in a "learning and transitioning period" and not up to full operational speed, but scientists at the National Solar Observatory recently released a batch of images that hint at what it's capable of. Several of the photos feature sunspots, cooler regions of the Sun with strong magnetic fields.
The sunspots pictured are dark and cool regions on the Sun's "surface", known as the photosphere, where strong magnetic fields persist. Sunspots vary in size, but many are often the size of Earth, if not larger. Complex sunspots or groups of sunspots can be the source of explosive events like flares and coronal mass ejections that generate solar storms. These energetic and eruptive phenomena influence the outermost atmospheric layer of the Sun, the heliosphere, with the potential to impact Earth and our critical infrastructure.
In the quiet regions of the Sun, the images show convection cells in the photosphere displaying a bright pattern of hot, upward-flowing plasma (granules) surrounded by darker lanes of cooler, down-flowing solar plasma. In the atmospheric layer above the photosphere, called the chromosphere, we see dark, elongated fibrils originating from locations of small-scale magnetic field accumulations.

Mosfilm, one of the largest film studios in the USSR during the Soviet era, has put full-length versions of many of its most acclaimed and influential films on YouTube for free, including six of Andrei Tarkovsky's films: Stalker, Solaris, Ivan's Childhood, The Mirror, Andrei Rublev, and The Passion According to Andrei. Also available is Battleship Potemkin by Sergei Eisenstein. Several of these movies appear on Sight and Sound's 2022 list of the best 100 movies of all time. (via @irwin)
Oh this is so nerdy and great: Veritasium introduces us to Micromouse, a maze-solving competition in which robotic mice compete to see which one is the fastest through a maze. The competitions have been held since the late 70s and today's mice are marvels of engineering and software, the result of decades of small improvements alongside bigger jumps in performance.
I love stuff like this because the narrow scope (single vehicle, standard maze), easily understood constraints, and timed runs, combined with Veritasium's excellent presentation, makes it really easy to understand how innovation works. The cars got faster, smaller, and learned to corner better, but those improvements created new challenges which needed other solutions to overcome to bring the times down even more. So cool.
The length of a human life is around 80 years. You might get 100 if you're lucky. The universe is about 13.7 billion years old. The vast difference between a human lifespan and the age of the universe can be difficult to grasp — even the words we use in attempting to describe it (like "vast") are comically insufficient.
To help us visualize what a difference of eight orders of magnitude might look like, Wylie Overstreet and Alex Gorosh have created a scale model of time in the Mojave Desert, from the Big Bang to the present day. This is really worth watching and likely to make you think some big think thoughts about your place in the universe and in your life.
This is a followup of the scale model of the solar system they built and a video they made about people seeing the Moon through a telescope for the first time.

Last week, popular YouTuber, author, and science communicator Hank Green announced that he had cancer (very treatable Hodgkin's lymphoma). His video announcement was part of a series of back-and-forth videos he does with his brother John Green, popular YouTuber and novelist. John replied to Hank's video with a short one of his own, noting that humor is one way that people deal with grief but also a way in which we can accompany people through tough times.
To work, the humor has to feel like love rather than judgment, like inclusion rather than stigma, and like celebration rather than dismissal. And that's a tough balance. Sometimes well-intentioned people, including me, get it wrong. And it also depends on, like, who's saying it and the context.
Good luck and my warmest thoughts to the Greens and their family as they navigate this difficult time. And, you know, fuck cancer.
