Thermomajorization theory provides new framework for quantifying mysterious Mpemba effect

The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when they are warm or colder. This effect was observed in various systems, including water, which sometimes freezes faster when it is hot than when it is cold. While it is now well-documented, the Mpemba effect remains poorly understood from a theoretical standpoint. This is partly due to the methods that conventional physics theories offer for quantifying the speed with which a system relaxes (i.e., its relaxation speed). Researchers at Kyoto University recently devised a new rigorous and unified approach for quantifying the Mpemba effect. The criterion they devised, presented in Physical Review Letters, is rooted in thermomajorization theory, a mathematical framework for comparing the disorder (i.e., entropy) between different thermodynamic states.

FINALIZED BETA GODTIERS YAHOO

[bluereset]

AGHH I FINALLY GET TO SHOW OFF THIS WORBLA PIECE I SPENT THE FIRST HALF OF THE SEMESTER WORKING ON IT AND HERE IT IS!!! It’s a Nightwing inspired piece, not too on the nose since it was for class and we have to do original designs, but I really love how it came out! This outfit was sort of just put together with what I had but feel free to use it if you want to for fan art just credit me please! Thank you! If we want better pics of just the breastplate let me know!

HAVE A FANTASTIC DAY, YOU ADORABLE THING YOU.

NO, YOU HAVE A FANTASTIC DAY, ANON! A damn KIWILICIOUS day even!!!

[skinteresting-enough]

A black cat walks up to a leg, and politely paws at it.

The camera zooms out to reveal that the leg belongs to Nimona. Nimona looks down at the cat, and shapeshifts into a pink cat herself.

The black cat startles at this for a bit, but as Nimona meows, they quickly calm down and meow back.

"You want to stand in this spot?" Nimona asks.

The cat meows once, then headbutts Nimona.

Nimona headbutts back affectionately, and then turns around and jumps down from where she first stood. The black cat moves to sit down in the now free spot, closes their eyes, and starts purring.

The camera zooms out further to reveal that the black cat and Nimona are standing on a tiered podium labeled "Mal's Top 3 Favorite Movies of All Time". Nimona is standing on the no.2 spot, and the cat is sitting in the no.1 spot. (The no.3 spot has a black bar over it for some reason.)

...

Yeah, Flow (2024) is definitely the movie of all time. Achingly lonely and hauntingly beautiful. Definitely give it a watch (preferably with some of your money attached, if you can afford it) sometime.

Now if you'll excuse me, I need to cry for a couple of hours.

Researchers discover new mechanism to cool buildings while saving energy

With temperatures rising globally, the need for more sustainable cooling options is also growing. Researchers at UCLA and their colleagues have now found an affordable and scalable process to cool buildings in the summer and heat them in the winter. Led by Aaswath Raman, an associate professor of materials science and engineering at the UCLA Samueli School of Engineering, the research team recently published a study in Cell Reports Physical Science detailing a new method to manipulate the movement of radiant heat through common building materials to optimize thermal management. Radiant heat, which is felt whenever a hot surface warms our bodies and homes and is carried by electromagnetic waves, travels across the entire broadband spectrum at ground level between buildings and their environments, such as streets and neighboring structures. On the other hand, heat moves between buildings and the sky in a much narrower portion of the infrared spectrum known as the atmospheric transmission window. The difference in how radiant heat travels between buildings and the sky versus the ground has long presented a challenge to cooling buildings with less skyward-facing surfaces. These buildings have been hard to cool in the summer as they retain heat from the ground and neighboring walls when the outside temperature is high. They are equally difficult to warm in wintertime as the outdoor temperature drops and the buildings lose heat.

2024 Movie Odyssey Award for Best Picture

Here now are my ten Best Picture winners for the last calendar year. A reminder that films that count towards the Movie Odyssey are movies that I saw in their entirety for the first time over that calendar year. Rewatches don't count.

In other words, these are my top ten "new-to-me" films from my 2024 viewings. I name all ten as "Best Pictures" in alphabetical order. I don't rank them. Any links in the titles take you to my write-ups... regrettably, there are only two:

Adam's Rib (1949; dir. George Cukor)

George Cukor's legal comedy comes with the tagline: "It's the hilarious answer to who wears the pants!" Spencer Tracy and Katharine Hepburn were long-unmarried romantic partners, and their professional partnership included nine films from 1942-1967. Here, he plays a prosecutor; she plays a defense attorney. While in court, Hepburn will claim that a woman’s (Judy Holliday) attempted murder of her adulterous husband is justified. Despite that crazy premise, Adam’s Rib sizzles: this is an ideal movie to watch if you want to know what the comedic and romantic chemistry between Tracy and Hepburn was like.

Awaara (1951, India; dir. Raj Kapoor)

In only his third feature film, Raj Kapoor directed himself, Nargis, and Rithviraj Kapoor (Raj’s father) in a gorgeously made Bollywood movie unafraid of asking questions of class, crime, capitalism/socialism, and personal redemption. The title, which can be translated to “tramp”, is only the first of several aspects in this film reflective of Raj Kapoor’s admiration of Charlie Chaplin’s silent films – humor, pathos, and social consciousness colliding, poetically, into a deeply human work. One of the few ‘50s Bollywood movies to achieve widespread popularity beyond India's borders: it's a touchstone in the former USSR nations, the Balkans, and China. You can watch it here.

The Big Heat (1953; dir. Fritz Lang)

One of two films noir here, this one by German director Fritz Lang (whose film M, from 1931, heavily influenced the creation of noir). Homicide Det. Dave Bannion (Glenn Ford) is investigating the death of a fellow cop when he receives word from “upstairs” to stop. He suspects a conspiracy, and turns in his badge (but not his .38) to get to the bottom of it. How far will he go? The Big Heat benefits from a cavalcade of excellent supporting actors – including Lee Marvin and especially Gloria Grahame. Don’t read reviews or other pieces before viewing this film: The Big Heat contains one of the most vicious moments in film history – unforgettable to anyone who sees it, not just to noiristas.

Detour (1945; dir. Edgar G. Ulmer)

Film noir #2 among this year’s Best Pictures. Edgar G. Ulmer’s Detour was made by “Poverty Row” studio PRC (derisively nicknamed “Pretty Rotten Crap”) and does so much with so little. Unemployed piano player Al Roberts (Tom Neal) is the unreliable narrator recounting how his life was destroyed after hitch-hiking cross-country to reunite with his girlfriend (Claudia Drake) and his encounter with maybe the meanest woman in film noir history, Vera (Ann Savage; what a surname). Detour’s tawdry, yet brilliant, filmmaking and unreliable narration subconsciously creates its own internal logic. This 68-minute film has the tone and rhythm of a nightmare. In the public domain. Best watched in the dead of night, half-asleep. Did you watch or dream this movie?

Dinner at Eight (1933; dir. George Cukor)

Ten years ago? George Cukor’s Dinner at Eight (Cukor again!) doesn’t make this list. I’ve taken a while to come around to comedies of manners. Based on the play of the same name with an adapted screenplay by Herman J. Mankiewicz, Dinner at Eight sees a socialite (Billie Burke, Glinda in The Wizard of Oz) organize a dinner party for all her friends. Also starring Marie Dressler, John Barrymore (whose fallen silent film actor character is alarmingly prescient), Wallace Beery, Lionel Barrymore, and especially a fantastic Jean Harlow, this is a racy, elegantly-costumed witty comedy of high society figures deceiving themselves about their stations in life.

Flow (2024, Latvia/Belgium/France; dir. Gints Zilbalodis)

One of two animated features this year. In only his second feature, Latvian director Gints Zilbalodis delivers a dialogue-free animated feature that follows a black cat and their companions in a boat while they navigate the world, which has been destroyed by water. Made with free software Blender, this is a remarkable production that, like Detour, succeeds beyond its paucity of resources. Zilbalodis – who also was co-producer, co-writer, co-composer, cinematographer, editor, and art director – will tell you not to sweat plot details. This is a movie that is about how one learns to trust and work with others – something that Zilbalodis, usually a one-man show, learned himself while making Flow.

One Way Passage (1932; dir. Tay Garnett)

Along with Dinner at Eight, this is one of two pre-Code films among the Best Picture winners. Tay Garnett’s romantic drama stars two major figures from the pre-Code era: William Powell and Kay Francis. On a monthlong ferry from Hong Kong to San Francisco, Francis plays a terminally ill woman (not that you could tell she was terminally ill) who falls for a murderer (Powell) who has escaped authorities and is bound to be hung. Despite what might appear to be a morbid premise, One Way Passage has a romantic delicateness to it, mixing light comedy with unsentimental gestures for a most curious concoction. Fantastic ending.

Son of the White Mare (1981, Hungary; dir. Marcell Jankovics)

As some of you may know, one of my cinematic blind spots that I am most aware is a blind spot and would like most to address is Eastern bloc animation. Marcell Jankovics’ Son of the White Mare is a mythological movie that takes elements of the creation myths of the ancient nomads of the Eurasian steppe. Our main character is Treeshaker, the third human son of a mare, who has superhuman strength. He later meets his two similarly strong older brothers, Stonecrumbler and Ironrubber. Our trio journey to defeat three dragons spreading evil across the world. Jankovics’ film may be standard folklore, but its visual splendor – bright and bold colors, representational character animation – has never been imitated.

​A Special Day (1977, Italy; dir. Ettore Scola)

No other Italian actors could fit the idea of glamor as much as Sophia Loren and Marcello Mastroianni. And in Ettore Scola's Una giornata particolare, the two inhabit roles far away from their public and on-screen personas. On the day of Hitler's arrival in Rome on May 3, 1938 to citywide celebrations, a housewife (Loren) and a recently-sacked radio announcer (Mastroianni) have a chance encounter. With everyone else in the apartment complex away to watch the pomp and circumstance, the two discuss their lives, their disappointments, and the expectations hoisted upon them by others. Both actors tap into their wartime experiences to deliver performances among the best of their careers.

20 Days in Mariupol (2023, Ukraine; dir. Mstyslav Chernov)

“It's painful to watch. But it must be painful to watch.” So narrates director Mstyslav Chernov. Produced by the Associated Press and PBS for the latter’s Frontline, 20 Days in Mariupol is a war documentary that captures the twenty days that Chernov and his fellow AP photojournalists spent in Mariupol at the beginning of Russia’s 2022 invasion of Ukraine before their dangerous escape. With spare narration from Chernov (that I think I could’ve done without), we see moments unfold that became some of the most infamous images of the conflict in those early weeks – all involving the suffering and deaths of civilians (including children). Essential journalism, harrowing filmmaking. Available on Frontline’s YouTube.

Flows

An easy exercise in heat transfer. It is, but the curious stuff in it resides in how circuits/electronics and heat flow work the same way bc of the "resistance" to thermal and electric flow do. Then, laminate the material causes the same effect in both phenomena heh.

[nineoftoads]

I am truly obsessed with how we develop like, ohm's and kirchoff's laws for circuit analysis and then we're like, oh cool we can apply this to like so many things that flow actually.

[buggbuzz]

i may be picky about everything else in the world but you will NEVER catch me picky about music i fucking love music so much. jazz, hyperpop, rap, lo-fi, rock, indie, even some classical, i dont give a fuck, i will listen to almost any genre if its got a good beat, a good flow, and a good melody.

sorry im just listening to chromakopia and its so fucking heat that its making me wanna wax poetry about the existence of music i love music so goddamn much. anyways go stream thought i was dead its making me lose my mind
