Amari and the Night Brothers by B.B. Alston is a work of magical creativity. All Amari wants to do is find her missing big brother. The detectives on the case think her brother is a runaway or into some no-good business. But Amari knows better. She locates a case left by her brother meant only for her. Inside is a secret message that sends her to a school for those with magical abilities, that only certain individuals with the right talent and skills can see and access. Amari doesn’t even know she has magical abilities! From there, it’s a battle to prove herself so she can stay at the school long enough to find clues to locate her brother. It’s an amazing read that will keep you hooked until the very twisted end.

A longstanding explanation for why perovskite materials make such good solar cells has been cast into doubt thanks to new measurements. Previously, physicists ascribed the favorable optoelectronic properties of lead halide perovskites to the behavior of quasiparticles called polarons within the material’s crystal lattice. Now, however, detailed experiments at Germany’s BESSY II synchrotron revealed that no large polarons are present. The work sheds fresh light on how perovskites can be optimized for real-world applications, including light-emitting diodes, semiconductor lasers, and radiation detectors as well as solar cells.

Lead halide perovskites belong to a family of crystalline materials with an ABX₃ structure, where A is cesium, methylammonium (MA), or formamidinium (FA); B is lead or tin; and X is chlorine, bromine, or iodine. They are promising candidates for thin-film solar cells and other optoelectronic devices because their tuneable bandgaps enable them to absorb light over a broad range of wavelengths in the solar spectrum. Charge carriers (electrons and holes) also diffuse through them over long distances. These excellent properties give perovskite solar cells a power conversion efficiency of more than 18%, placing them on a par with established solar-cell materials such as silicon, gallium arsenide, and cadmium telluride.

Researchers are still unsure, however, exactly why charge carriers travel so well in perovskites, especially since perovskites contain far more defects than established solar-cell materials. One hypothesis is that polarons – composite particles made up of an electron surrounded by a cloud of ionic phonons, or lattice vibrations – act as screens, preventing charge carriers from interacting with the defects.

In a triumph of observation and data processing, astronomers at the Event Horizon Telescope have captured the first-ever picture of the supermassive black hole at the center of the Milky Way Galaxy.

The black hole is named Sagittarius A* (pronounced “A-star”), and the reveal of its image received an international rollout this morning in simultaneous press conferences held by the National Science Foundation (NSF) at the National Press Club in Washington, D.C., and the European Southern Observatory headquarters in Garching, Germany.

The image represents 3.5 million gigabytes of data taken at millimeter wavelengths by eight radio telescopes around the world. “It took several years to refine our image and confirm what we had,” said Feryal Özel, an astronomer at the University of Arizona in Tucson, at the NSF press conference. “But we prevailed.”

When galaxies collide, the central supermassive black holes that they contain begin to orbit each other. This supermassive black hole binary attracts gas, which flows through the system to form two disk-shaped structures, one around each of the supermassive black holes. The gas in these “minidisks” heats as it falls toward the holes and begins to radiate light. Astronomers have detected around 150 galaxies with candidate supermassive black hole binaries. And, as observations become more detailed, they expect the light from the minidisks in those systems to bear recognizable, time-dependent signatures from black hole distortions [1]. Now, Jordy Davelaar and Zoltán Haiman of Columbia University have theoretically tested how one such distortion—the “shadow” of the black hole—affects this light signature, finding that it causes a dip in the signal that should be observable in about 1% of candidate systems [2, 3]. The technique could allow astronomers to study black holes that are currently beyond the reach of conventional imaging methods (Fig. 1).

From gravitational-wave measurements of merging black holes to direct imaging of the plasma circling a black hole, the last decade has seen an explosion of observational evidence for black holes (see Viewpoint: The First Sounds of Merging Black Holes and News Feature: Black Hole Imaging Tests Einstein’s Limits) [4–6]. Yet despite these achievements, many questions remain about black holes, including a critical one: How do black holes grow to supermassive scales—millions to billions of times the mass of the Sun?

A black hole is a simple object, described by its mass, angular momentum, and electrical charge. Supermassive black holes are typically electrically neutral, so their mass and angular momentum parameters determine their gravitational fields. The gravitational field determines how the black holes bend light and thus how they appear to an observer on Earth. Light passing near the black hole is deflected by the gravitational field, producing a black hole shadow—a dark region that is often encircled by a bright light ring—whose size and shape come directly from the black hole’s mass and angular momentum.

Vladimir Putin is a reality daytrader. His invasion of Ukraine is a "special military operation," not a war, or more accurately, an ongoing war crime. Gaslighting eleven Russian time zones is as easy to him as flatulence. With the GRU and American social media, he can hack American minds with the wildest conspiracy theories almost at will. The ridiculous QAnon claptrap that democrats are "demon-spawned, blood-drinking pedophiles" sounds like a propaganda tactic from the Kremlin:

Putin befriended and supported European politicians who were willing to defend Russian interests. One was Gerhard Schroder, the retired German chancellor, who was in the employ of the Russian gas company Gazprom. A second was Milol Zeman, elected president of the Czech Republic in 2013 after a campaign partly financed by the Russian oil company Lukoil, and reelected in 2018 after an election financed by unknown sources. A third was Silvio Berlusconi, who shared vacations with Putin before and after leaving the office of Italian prime minister in 2011. In 2013, Berlusconi was convicted of tax fraud and banned from public office until 2019. Putin suggested that Berlusconi's true problem was the persecution of heterosexuals. "If he were gay, no one would ever lay a finger on him." Here Putin was enunciating a basic principle of his Eurasian civilization: when the subject is inequality, change it to sexuality. In 2018, Berlusconi began a political comeback.

"The Road to Unfreedom: Russia, Europe, America," by Timothy Snyder, page 100 (paperback), author of "On Tyranny."

Gallop shows the number of adults self-identifying as LGBT ticking up to 7.1% isn't evidence of lower testosterone any more than it is of mythical cooties. We've gone from "Will and Grace," the sitcom "Soap," Ellen DeGeneres, and Rachel Maddow on primetime television to legalizing same-sex marriage as a Constitutional Right. At least on the surface, we seem to be more tolerant. Math question: isn't 7.1% less than 92.9%?

Or, take nonexistent voter fraud. The Brennan Center "found incident rates between 0.0003 percent and 0.0025 percent." Red states are making laws over something more infinitesimal than pocket lint.

An election happened in 2020, and the Russian asset (emphasis on the first syllable), lost. He couldn't even admit the truth to his friend Piers Morgan, telling him "what if you're not real?" In typical duplicitous snowflake fashion, he stormed out when confronted with the truth: he lost. Did we give this ingrate the nuclear codes?

Vance: Some opposition to Obama ‘comes from the color of his skin’

Vance also previously advanced [a] defense of former President Barack Obama, a Democrat who was the country’s first Black president, and who was falsely labeled a Muslim and was the subject of the racist “birther” conspiracy. Vance said he admired Obama for his personal accomplishments, even though he disagreed with him politically.

J.D. Vance used to admonish Donald Trump’s ‘xenophobic’ appeals to voters. Until he decided to run for Senate. Clevland.com

The "Big Lie" as popularized by Timothy Snyder in "Bloodlands" and executed by Vance and the American "son of perdition" has become less of a loyalty test, and more of a chanted mantra, eerily similar to Orwell's "two minutes hate" ritual. Yet, part of being in a cult means you curate reality: you daytrade it to avoid pain and steamroll up Maslow's pyramid to self-actualized pleasure. "Freedom" isn't the freedom to say two plus two equals four, it's the ability to troll on Twitter without fact check, or the threat of banning. (That worked out really well on January 6th.) What is painful to admit must be a conspiracy, not the outcome of voter mobilization, or concerns about fascism. "Others" - women, people of color, LGBT, youth - who did not vote for their Gollum avatar are "unpersons," and therefore since they do not exist, their votes are by definition fraudulent. Dehumanization is the first stage before slaughter and genocide.

Actual voter fraud committed during the 2020 election was committed by the followers of Putin's asset's personality cult. History has no impact and facts do not matter. Karl Rove opined about "creating realities" and for Putin and Russophiles like Rand Paul, Ukraine doesn't exist because it never existed. Therefore, uncomfortable histories about "your tribe" in the formation of the US must be banned, and I'm sure eventually, burned.

“Who controls the past controls the future. Who controls the present controls the past.”

“The best books... are those that tell you what you know already.”

“If you want to keep a secret, you must also hide it from yourself."

"Oceania has always been at war with Eastasia. Since the beginning of your life, since the beginning of the Party, since the beginning of history, the war has continued without a break, always the same war."

-George Orwell, "1984"

Alternative facts. Big lies. Created realities. These things are not the basis for democracy, and two plus two is not five.

“Now I will tell you the answer to my question. It is this. The Party seeks power entirely for its own sake. We are not interested in the good of others; we are interested solely in power, pure power. What pure power means you will understand presently. We are different from the oligarchies of the past in that we know what we are doing. All the others, even those who resembled ourselves, were cowards and hypocrites. The German Nazis and the Russian Communists came very close to us in their methods, but they never had the courage to recognize their own motives. They pretended, perhaps they even believed, that they had seized power unwillingly and for a limited time, and that just around the corner there lay a paradise where human beings would be free and equal. We are not like that. We know that no one ever seizes power with the intention of relinquishing it. Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power. Now you begin to understand me.”― George Orwell, 1984, all quotes in italics from Good Reads
