Rediscovering Réaumur: The Forgotten Temperature Scale | May 28 2026, 21:48

LOL, it turns out that besides Fahrenheit and Celsius scales, there was another scale, and relatively recently. The attached photo is mine, taken in 2009 in Baku at a friend’s house.

So where did this Réaumur come from? In 1730, he proposed a temperature scale, one degree of which equals 1/80 of the difference between the boiling point of water and the melting point of ice. Why 80? Because it’s easier to remember, although in fact Réaumur took only one reference point – the melting point of ice. Hence, the “zeros” of the Celsius and Réaumur scales coincide. And one degree of Réaumur corresponds to a temperature change during which the volume of alcohol increases or decreases by 1/1000.

In Réaumur’s days, there were already several different scales, including the widely known Fahrenheit scale, which is still used in some countries, including the States (and which I have never gotten used to). In France, the use of this scale was abolished on April 1, 1794, in connection with the transition to the metric system. The Réaumur scale was used in Tsarist Russia until the 1917 revolution. But in general, the 18th century was a mess with this, and few people know that besides these Kelvin, Celsius, and Fahrenheit, their scales were also invented by Rankine, Rømer, Newton, Delisle, and Réaumur.

Vodka and Revelations: Notes from “Project Hail Mary” Unseen in Film | May 25 2026, 04:15

I’m almost finished with Project Hail Mary. I’ll write separately about my impressions. Today – some notes along the way that somehow didn’t make it into the movie.

Russian engineer Olesya Ilyukhina drinks vodka from a frighteningly large glass at a meeting, and during the rocket launch, she joyfully screams and downs one shot after another. In her personal baggage for the space flight, 5 liters of vodka in bags are found. Grace directly asks the Russian scientist Dmitry: “Are all Russians crazy?”, to which he smiles and replies: “Yes. It’s the only way to be Russian and happy at the same time.” Ilyukhina, planning her own death, asks to be provided with heroin. She wants to die from an overdose to experience “maximum pleasure” before death (while the Chinese Yao pragmatically chooses a gun). During the launch of the ship’s modules (cabin, laboratory, and sleeping compartment), broadcasted from the Flight Control Center in Moscow, Russian cosmonaut Olesya Ilyukhina drinks vodka and yells at the TV: “Don’t screw up my home, bastards from Roscosmos!” But overall, Russian space technologies are occasionally even praised – for instance, it is claimed that experts from around the world have recognized the Russian “Orlan” spacesuit as the safest and most reliable, so it is used in the mission.

When the main character (Grace) sees the Black American scientist Martin Dubois, he turns to the project director Stratton: “Dubois turns out to be Black! Surprising that you allowed that! Aren’t you afraid he’ll ruin the mission with talk about rap music and basketball?”

When they decide to send Grace to space forcibly, they lock him in a special room at the Baikonur Cosmodrome. This room resembles a college dormitory but has a steel door and bars on the windows. The hero quips about this: “Why is there a prison cell at the Baikonur launch complex? I don’t know. Ask the Russians.”

Grace complains about how the work with malfunction reports is organized during the spaceship’s preparation. Instead of sending an email, they bring him stacks of paper documents. Grace: “Because Russians do things a certain way, and it’s easier to work with them than to complain about it.”

Out of scientific curiosity, Grace decides to observe how his alien friend Rocky eats. It turns out, Rocky is a “monostome”, meaning he both eats and excretes through the same opening in his body. Grace watches as a gray lump falls out of the alien’s stomach with a moist sound, after which Rocky tosses pieces of fresh meat into the same opening. Grace concludes: “The subject defecates from the mouth… Yep, that was pretty disgusting.”

The caricature nature of the characters, stereotypes, fantastic coincidences, and “plot contrivances” like deus ex machina are somewhat annoying.

The Radical Survival Strategy of Elysia marginata: Decapitation and Regrowth | May 24 2026, 21:10

Today I learned about the sea slug Elysia marginata, which (I quote) can lose its head like no other: when this slug is overwhelmed by parasites, it doesn’t go on marathons to Instagram gurus but takes a radical approach — it detaches its head and starts a new life. (I quote Anna Fe above and below because I learned everything from her post) The slug’s neck has a special groove labeled “cut here.” The head separates along this line, not immediately, but over several hours. Having shed its fatty, annoying body, the head, giggling, crawls away, saying “goodbye” to its former self – along with all the parasites, and also with the heart, kidneys, intestines, and reproductive organs. The slug survives understandably – “like everyone else, using its head (it eats with it).”

And here I started thinking: is the definition of a head—where you eat from? How do biologists understand where the head is in some fantastical creature? For example, does a sea cucumber have a head?

I Googled it. Wow, interesting. No, the head is not where you eat from. It is what first encounters the surrounding environment when moving forward. Since this end needs to quickly understand what’s ahead (danger or food), during evolution, two things concentrate there:

1) Main sensory organs (eyes, antennae, locators, chemical receptors)

2) CNS (brain or the largest nerve nodes – ganglia), to instantly process the information received from these organs.

Therefore, they write, when a biologist looks at an unknown fantastical thing,” he looks not for the mouth, but for the main control point. Where there is the highest concentration of nerve cells and receptors, there is the head.

But let’s return to the independent head of the slug. How does it manage without a stomach?

These slugs feed on algae and are able to retain their chloroplasts (structures for photosynthesis) in their tissues. Thus, the head temporarily turns into a plant and gets energy directly from sunlight, while it regrows its new body. The wound on the neck heals within 2 days, a new heart takes about a week to grow, and a fully new torso with all organs—just 20 days.

The former body, meanwhile, just lives its life on the ocean floor. Its heart beats and nerves feel, but poor thing, it cannot eat and eventually dies from exhaustion.

Asian Fair Discovery: The Uni-ball Pen and Its Surprising Study | May 18 2026, 18:13

We recently had an Asian fair here – Japanese, Chinese, Korean goods, and street food. We bought a pie and some kind of pen for 6 bucks from Japanese vendors, which they beautifully packaged and asked for a review on Instagram. The pen is just a pen. Compared at home with our existing gel pens – no difference. But I Googled it out of curiosity.

“These inks are not just good-looking — they can even help you learn better. A study conducted at Ritsumeikan University in Japan showed that students who reviewed material from notes written with a black Uni-ball One pen retained information better than those who read notes made with regular black ink.”

I wonder who conducts such ridiculous research and who orders it. No surprises at all. Mitsubishi Pencil (the manufacturer of Uni-Ball) goes to the university, finds Professor Masashi Hattori (服部雅史) from the psychology department at Ritsumeikan University, and he organizes a report about a ‘memory reproduction task’ conducted on high school students: it compared the memorization of handwritten text with pens of different ink density, resulting in the conclusion that text written with dense black ink from the sponsoring company was reproduced more accurately than with regular gel ink.

Some of the co-authors of the report were Mitsubishi Pencil employees. There was no peer-reviewed article, only a conference presentation at the 38th Congress of the Japanese Society of Psychonomics (日本基礎心理学会第38回大会) on December 1, 2019; the results were also presented at the 32nd International Congress of Psychology ICP 2020+.

So, that’s the story with this pen 🙂

Comparing Work Cultures: From Conflict to Courtesy | May 15 2026, 15:12

I reminisce about working on various projects and in different companies up until 2016, comparing it with what I see from the USA (projects in the USA, Europe, and Asia), and I notice one interesting thing – there are no screaming matches during calls, no hysterical outbursts, no unhinged managers yelling at everyone around, and getting upset over every little thing. There are no overt conflicts. Of course, there are still covert games and politics, but if someone is unpleasant to someone else, they do it with a smile and politely (though, overall, not often).

In my past life,” this was a common occurrence that nobody really considered abnormal. Especially if the hysterics were over some genuinely important work issue, and the person was truly passionate about the results.

What I’m really interested in is – what has changed? There are four likely explanations, probably working in conjunction:

1) I moved to the USA

2) times are different

3) people are on meds

4) online etiquette is different.

There’s also an obvious fifth reason – “I have changed,” but it doesn’t quite fit here, because I’m not talking about conflicts involving me or with me, but about observing others’ interactions, which are unlikely to have changed. From my perspective, as I observe, interactions during meetings have become much kinder, but I can’t tell if times have really changed everywhere or if Russian companies are still the same, and I just don’t see it for obvious reasons. Or is it the nuances of online meetings, where yelling at a computer somehow feels odd? We’re talking about major serious companies, not a meeting at a city sports committee.

Human Behavior Under Isolation: Lessons from the SPHINX Experiment | May 10 2026, 18:01

In the book Project Hail Mary, Stratt tells Grace that in the USSR there was supposedly an experiment where people were locked up for several months to see what would happen, and that the people almost killed each other, leading to the experiment being halted. That wasn’t the case, but I googled and found there was another experiment – SPHINX in 1999.

There were several groups. In the first, there were four Russians and during the New Year celebrations with alcohol, they beat each other up (10 minutes, blood, they had to be pulled apart). Another group had three guys and a girl (Judith Lapier) and the mission ended because during the New Year’s celebrations, driven by excitement, Judith was attempted to be kissed twice, leading to the mission being terminated.

As VICE reports, the dialogue was “We should try kissing, I haven’t smoked for six months. Then we can kiss after the mission and compare. Let’s experiment now.”

The team included doctors with degrees (Lukyanuk, Karashkin, Murashov) and Haider Hobikhozhin, who essentially was a randomly included technician with secondary education, taking the place of the Japanese man to the right in the photo and who was first in the second photo. Who beat up or kissed whom is now somewhat forgotten.

Vadim Gushchin, a coordinator from IMBP, after the scandal stated that the fight was “friendly,” and that Lapier “ruined the mission, the atmosphere, by refusing to be kissed.”

At the Canadian Space Agency, Lapier was told that such behavior is normal for Russians and that public complaints would be considered taboo in the culture of the host country.

Navigating Simple English in “Project Hail Mary” | May 10 2026, 15:30

I’ve read about a quarter of Project Hail Mary so far. The English is very simple, easy to read, captivating; the movie so far follows the book closely, but still, it makes reading quite interesting. However, I generally find it hard to read fiction because I keep getting distracted to google stuff. I reached the phrase “..I used the bathroom (or “head” I guess, because I was on the ship)…” and it got me thinking, it’s interesting to learn that the toilet is called differently on a ship not just in Russian. And why “head”? Turns out that “galley” in Danish and German is “head”. Interestingly, galleys are also found on airplanes, and historically, galleys were used only by sailors; officers did not use them.

The text is very childish, and understandably so – the main character is a physics teacher at a school after all. All these motherfluffer and dang it, gosh darn it, fudge, holy moly, for cripes’ sake instead of for Christ’s sake, there’s even bull-puckey instead of bullshit. “To go wee” is how they say “to pee” in the book. I recall, the day before yesterday we entered a mattress store, and the consultant, while discussing the topic “if one of you goes to the toilet, the other won’t even notice that the first one got up” – well, because the mattresses are so soft – actively used the verb “to pee”. So what? 🙂

Update: when the physics teacher encounters an alien ship on page 120, the chapter ends with holy fucking shit! That’s what all the rest was leading to;)

Occasionally, there are quite funny expressions that can even be used in life 🙂 For instance, the main character asks, “Who pooped in your Rice Krispies?” which is the idiom “to poop in someone’s cereal” – “who messed up your meal”.

In conclusion, if you’re choosing your first book to read in English – this one is at the top of my list. Even something seemingly simple like “Harry Potter” is more sophisticated, in my opinion. Here, there’s a lot of dialogue, school level but almost slang-free vocabulary, and a pretty interesting plot. Plus, it’s real science fiction, where the author educates the reader about the scientific method, how the world works, etc., all from the viewpoint of the hero, a physics teacher, who shares various facts and thoughts on how physics works, relating it to the plot in his interactions with other characters or thoughts to himself (rather than directly to the reader). It’s middle school level so far, but maybe it’ll get more complex later on.
