Neuenschwander (2011), Dwight E, Emmy Noether's Wonderful Theorem, Johns Hopkins University Press 2011 Jacket: A beautiful piece of mathematics, Noether's theorem touches on every aspect of physics. Emmy Noether proved her theorem in 1915 and published it in 1918. This profound concept demonstrates the connection between conservation laws and symmetries. For instance, the theorem shows that a system invariant under translations of time, space or rotation will obey the laws of conservation of energy, linear momentum or angular momentum respectively. This exciting result offers a rich unifying principle for all of physics.'

Affine geometry - Wikipedia, Affine geometry - Wikipedia, the free encyclopedia, 'In mathematics, affine geometry is what remains of Euclidean geometry, when not using (mathematicians often say "when forgetting") the metric notions of distance and angle. As the notion of parallel lines is one of the main properties that is independent of any metric, affine geometry is often considered as the study of parallel lines. Therefore, Playfair's axiom (given a line L and a point P not on L, there is exactly one line parallel to L that passes through P) is fundamental in affine geometry. Comparisons of figures in affine geometry are made with affine transformations, which are mappings that preserve alignment of points and parallelism of lines.' back

Al Jazeera, AP, California unveils the US’s first slave reparations report, ' California’s task force on reparations for Black people in the United States – the first-ever in the nation – has released a report documenting in detail discrimination perpetrated by the state and recommending steps to address those wrongs. The 500-page document released on Wednesday lays out the harms suffered by descendants of enslaved people long after slavery was abolished in the 19th century, through discriminatory laws and actions in all facets of life, from housing and education to employment and the legal system. “Four hundred years of discrimination has resulted in an enormous and persistent wealth gap between Black and white Americans,” according to the interim report of the California Task Force to Study and Develop Reparation Proposals for African Americans.' back

Bianca Fileborn & Sophie Hindes, Catcalls, homophobia and racism: we studied why people (and especially men) engage in street harassment, ' A growing body of research shows public harassment is among the most prevalent forms of sexual and gender-based violence. Street harassment can include homophobic, transphobic, racist and ableist actions, as well as overtly hostile and aggressive behaviour. . . . Our participants’ explanations of why men harass paint a complex and multifaceted picture. While harassment is firmly situated in the spectrum of violence against women, a more holistic approach is needed addressing homophobic, transphobic, racist and ableist harassment. It’s clear street harassment requires interventions targeting individual, cultural and structural drivers. The normalisation of street harassment requires urgent attention, so this behaviour is no longer excused.' back

Bill Hare, The ultra-polluting Scarborough-Pluto gas project could blow through Labor’s climate target – and it just got the green light , 'The Albanese government has this week thrown its support behind what’ll be one of Australia’s most polluting developments: the Scarborough-Pluto gas project in Western Australia. Our analysis last year found the full Scarborough-Pluto project will emit almost 1.4 billion tonnes of greenhouse gases over its lifetime. That’s over three times Australia’s current annual emissions, and around 14 times WA’s annual emissions. . . . Gas simply has no place in the fight to stop global warming beyond 1.5℃ this century. The big question is whether the Albanese government, if it wants to be taken seriously on climate change, will take that on board. Right now, given the high-profile intervention from the resources minister providing “absolute” support for Woodside and gas developments, the jury unfortunately is well and truly out.' back

Camille Gijs & Stephan Faris, Lumumba's tooth: Belgium's unfinished reckoning with its colonial past, ' Then comes a darker period. The tooth’s owner is Patrice Lumumba, the first democratically elected prime minister of Congo, a man many want dead. In 1961, Lumumba is assassinated, his body is buried, disinterred, dismembered and dissolved in acid. The tooth is preserved — brought to Belgium by a Belgian police officer named Gérard Soete as what he later describes as “a type of hunting trophy". . . . Today, Lumumba’s tooth is the center of attention, as the Belgian government gets ready to hand it over to his family as the independence leader’s only known remains. For now, it sits in a “custom-made box” in a safe in the offices of the Belgian federal prosecutor in downtown Brussels, according to Eric Van Duyse, spokesperson for the prosecutor’s office. But on June 20, Belgian Prime Minister Alexander De Croo will formally hand it over to Lumumba’s descendants, in what is planned to be the first step on its journey back to the country of its origin.' back

European wars of religion - Wikipedia, European war of religion - Wikipedia, the free encyclopedia, ' The conflicts began with the minor Knights' Revolt (1522), followed by the larger German Peasants' War (1524–1525) in the Holy Roman Empire. Warfare intensified after the Catholic Church began the Counter-Reformation in 1545 against the growth of Protestantism. The conflicts culminated in the Thirty Years' War, which devastated Germany and killed one-third of its population, a mortality rate twice that of World War I. The Peace of Westphalia broadly resolved the conflicts by recognising three separate Christian traditions in the Holy Roman Empire: Roman Catholicism, Lutheranism, and Calvinism. Although many European leaders were sickened by the bloodshed by 1648, smaller religious wars continued to be waged in the post-Westphalian period until the 1710s, including the Wars of the Three Kingdoms (1639–1651) on the British Isles, the Savoyard–Waldensian wars (1655–1690), and the Toggenburg War (1712) in the Western Alps.' back

The Palestinian flag is the flag of the Palestinian people, and it is to be hoped that one day it will be the flag of a Palestinian state established alongside Israel. In addition, formally speaking, the Palestinian flag is the flag of the Palestinian Authority, an authority established by diplomatic treaty with Israel.

Hilbert's axioms - Wikipedia, Hilbert's axioms - Wikipedia, the free encyclopedia, ' Hilbert's axioms are a set of 20 assumptions proposed by David Hilbert in 1899 in his book Grundlagen der Geometrie[ (tr. The Foundations of Geometry) as the foundation for a modern treatment of Euclidean geometry. Other well-known modern axiomatizations of Euclidean geometry are those of Alfred Tarski and of George Birkhoff. . . . Mathematics in the twentieth century evolved into a network of axiomatic formal systems. This was, in considerable part, influenced by the example Hilbert set in the Grundlagen. A 2003 effort (Meikle and Fleuriot) to formalize the Grundlagen with a computer, though, found that some of Hilbert's proofs appear to rely on diagrams and geometric intuition, and as such revealed some potential ambiguities and omissions in his definitions.' back

Ian Sample, Research may reveal why people can suddenly become frail in their 70s, ' Working with scientists at the Wellcome-MRC Cambridge Stem Cell Institute, Campbell and his colleagues studied blood cells across the age range from newborns to people in their 70s and 80s. They found that adults under 65 had a wide range of red and white blood cells produced by a diverse population of 20,000 to 200,000 different types of stem cells in their bone marrow. In the over-65s, the picture was radically different. About half of their blood cells came from a measly 10 or 20 distinct stem cells, dramatically reducing the diversity of the person’s blood cells, with consequences for their health.' back

Kakutani fixed-point theorem - Wikipedia, Kakutani fixed-point theorem - Wikipedia, the free encyclopedia, 'In mathematical analysis, the Kakutani fixed-point theorem is a fixed-point theorem for set-valued functions. It provides sufficient conditions for a set-valued function defined on a convex, compact subset of a Euclidean space to have a fixed point, i.e. a point which is mapped to a set containing it. The Kakutani fixed point theorem is a generalization of Brouwer fixed point theorem. The Brouwer fixed point theorem is a fundamental result in topology which proves the existence of fixed points for continuous functions defined on compact, convex subsets of Euclidean spaces. Kakutani's theorem extends this to set-valued functions.' back

Mark Satta, Putin’s brazen manipulation of language is a perfect example of Orwellian doublespeak, ' Putin’s brazen manipulation of language is drawing attention. Kira Rudik, a member of the Ukrainian Parliament, recently said of Putin in a CNN interview: “When he says, ‘I want peace,’ this means, ‘I’m gathering my troops to kill you.’ If he says, ‘It’s not my troops,’ he means ‘It’s my troops and I’m gathering them.’ And if he says, ‘OK, I’m retreating,’ this means ‘I’m regrouping and gathering more troops to kill you.’” As a philosophy professor who studies the British author George Orwell, I am reminded by Rudik’s comments about Putin of another set of claims: “War is peace. Freedom is slavery. Ignorance is strength.” These are the words etched onto the side of the building for the government agency called the “Ministry of Truth” in Orwell’s dystopian novel “1984,” published in 1949.' back

Moira Donegan, The Amber Heard-Johnny Depp trial was an orgy of misogyny, ' For their part, Depp’s fans seem to not so much deny Depp’s alleged violence against Heard, but to approve of it. “He could have killed you,” says one viral Tiktok supporting Depp, the text superimposed over photos of Heard’s bruised face. “He had every right.” The post has more than 222,200 likes. . . . In some ways, one could see the defamation suit itself as an extension of Depp’s abuse of Heard, a way to prolong his humiliation and control over her. The only difference is that now, the legal system and the public have been conscripted to take part. This seems to be at least partly how Depp sees it. In 2016, as their marriage broke apart, Depp texted his friend Christian Carino, vowing revenge against Heard. “She is begging for global humiliation,” Depp wrote. “She is going to get it".' back
