Scientists can obviously be political in their private life. But looking at the world through the political lens in your academic work is going to cause serious distortions that will lead to bad science and make the public lose their trust in the academia 👇
Scientists & science journalists decry the public's rejection of science, but are oblivious to the major cause: the perception, sometimes correct, that scientists are just another political faction. Among the guiltiest perpetrators are the recent editors of Scientific American, who turned this once-beloved treasure into a left-wing propaganda rag. This absolutely does not justify the Trump administration's unconstitutional meddling, but the new owners are right to restore it to its mission of explaining science to Americans.

That the Communist hammer and sickle isn’t commonly regarded as evil and offensive as the Nazi swastika is a failure of education.
“Dear Italian students, who today take to the streets carrying flags with the hammer and sickle and wearing T-shirts emblazoned with ‘CCCP’,” began an open letter in Italian by Lithuanian expat Neringa Budryt. “I would like to ask you a question: do you truly know what the symbols you carry represent? And do you know what would have happened to many of you had you openly demonstrated in countries living under the oppression of communist regimes? Let me tell you something. It is easy to display a red flag when, for you, communism is merely an abstract idea of equality, social justice, and rebellion against the system. It is easy to wear a T-shirt with "CCCP" on it when you have never experienced the reality of a communist regime. We come from that part of Europe where communism was not a T-shirt, a symbol of rebellion, or a romanticized notion of equality. It was the system in which we lived—a system we never chose. We know the history of Soviet repression, Stalinist purges, the Gulags, and mass deportations. Above all, we know the word "Siberia"—a place to which thousands of innocent people were forcibly deported, simply for thinking differently. In Siberia—amidst freezing cold, starvation, and forced labor—many lost their lives; those who survived carried the scars of that experience forever. Entire families were torn apart, and generations were denied the chance to live freely in their own homeland. In the countries of the Soviet bloc, censorship, political police, surveillance, and the suppression of dissent drastically curtailed individual freedoms. We grew up in a system where state control permeated even our daily lives. At school, we were required to wear the red necktie of the "Pioneers." We were monitored; they tracked where we went and even whether we attended church. Even faith—a choice that should belong to an individual’s own conscience—could become a cause for suspicion. We used to celebrate Christmas with our windows blacked out, to ensure no one would see us and report us. Because it was forbidden—just like so many other things: jeans, rock music, and all the symbols of a Western lifestyle. My mother returned from a Soviet labor camp. And do you know what happened to her? She was barred from continuing her education because she had been labeled an enemy of communism. Under a communist regime, you could not protest. You risked arrest, imprisonment, interrogation, persecution—and, in certain historical contexts, even death. In the Soviet Union and other communist regimes, political dissent could cost you your freedom and your life. Demonstrations independent of the authorities were not a guaranteed right; they were often suppressed by force. That is why it strikes me to see young Italians proudly displaying the hammer and sickle—symbols associated with regimes that persecuted and imprisoned millions of people. Today, you are free to take to the streets, shout against the government, criticize institutions, and wave your flags precisely because you live in a democracy that grants you these freedoms. Under an authoritarian regime of that kind, protesting against those in power could have landed you in prison. This is not about denying the existence of social injustices, inequalities, or the right to fight for a better world. You are free to take to the streets to demand a more just society—but you should not idealize a system that denied so many people the very things you are free to exercise today: the right to choose, to believe, to speak, and to dissent. Before wearing a T-shirt with "CCCP" on it, listen to those who experienced that world. Talk to the deportees and their descendants; read the accounts of those who endured the gulags and forced exile to Siberia. Learn what it meant to be stripped of your freedom, your home, your loved ones—and even any prospect of a normal life—simply because of your background or your beliefs. Before waving the hammer and sickle, please, study history thoroughly.”

Reminder: The Coolidge Effect is the observation that males have greater sexual responsiveness to and lower sexual refractory periods with multiple females. The name comes from an old joke: President Coolidge and his wife were being separately toured around a government farm. Mrs. Coolidge was brought to the chicken yard. She noticed that a rooster was having a lot of sex. She asked the farmhand how often he had sex and the farmhand said "Dozens of times each and every day." Mrs. Coolidge remarked "Tell that to the President when he comes by." Upon being told about this rooster's prodigious copulation, the President asked, "Same hen every time?" "Oh, no, Mr. President, a different hen every time." "Tell that to Mrs. Coolidge."

"Food insecurity" is a misleading term. If you didn't know any better, you'd imagine it was associated with chronically missed meals. The food insecure are actually considerably fatter!

This is an abominable tweet. She is *criticizing* these decent men and women for coming together to repel the marauders and protect their city’s shops. But these are exactly the kinds of citizens healthy societies cannot function without.
À Tours, des habitants ont organisé une chaîne humaine de 200 personnes pour témoigner leur solidarité aux…boutiques. Oui, oui. Ils nous ont fait un « soutien aux familles des vitrines » sauf que ce n’était pas du tout sarcastique. Les vitres > nos vies. Photo : Radio France.

Paljastetaan nyt ratkaisu laskutehtävään "paljonko miljardööri tienaa 29 minuutissa?". Omaisuuden arvonnousu ei ole "tienaamista", mutta tällaista oletusta tehtävä vaatii ollakseen ratkaistavissa, joten tehdään laskut tällä oletuksella ja 8% realistisella vuosituotolla 👇

Väite "miljardööri tienaa 29 minuutissa 50 000" euroa on siis yli kymmenkertaisesti väärin. Ehkä tällainen skaalausvirhe on politiikassa pikkujuttu, mutta veikkaan että palkansaajaa ottaisi kyllä pattiin jos tilille ilmestyisi palkkapäivänä sovitun 3000€:n sijaan vain 300€.

Tämä keskustelu on vailla järkeä. Koskelan kateusveroheittojen ainoa tarkoitus on ylläpitää mielikuvaa luokkavihollisista. Ei ne rikkaat palkansaajien rahoja vie. Sen tekee valtio kaikenmaailman minjakoskeloiden siunaamana. Rikkaat haluaa ottaa sut töihin ja maksaa sulle vuosi vuodelta suurempaa liksaa. Siihen ei Vasemmistoliitto oikein taivu.
Miljonääriverovideo on saanut paljon kritiikkiä (ja vielä enemmän turhaa öyhötystä). Kiva juttu, että aihe puhututtaa Miljonääriverossa on siis kyse 1% varallisuusverosta yli miljoonan omistuksille poislukien oma asunto. Vastataan nyt muutamaan huomioon: 1/6

Kapitalismi toimii niin tehokkaasti, että köyhyys on maapallolla katoava luonnonvara. Elintaso nousee laskentatavasta riippumatta. Suomessa ei ole ollut absoluuttista köyhyyttä aikoihin ja "suhteellisen köyhyyden" käsite on ollut pakko keksiä että köyhiä ylipäätään enää löytyisi!
No matter what poverty line you choose, the share of the global population below it has declined. The World Bank's International Poverty Line is an extremely low poverty line. Set at $3 per day, it draws attention to the living conditions of the poorest people on the planet. In the chart above, you can see how the share below this poverty line has declined over the last generation. In the year 2000, 36% of the world’s population lived on less than $3 per day. In 2024, it was 10%. But is progress against global poverty only happening when measured against such a very low poverty line? The chart gives the answer. The entire blue line is below the entire dark red line. This tells us that no matter what line you choose, the share below it has declined globally. Progress against higher poverty lines has been large, too. The share living on less than $5 a day has declined from 57% to 25%, and the share living on less than $10 a day has declined from 74% to 53%. But on the right-hand side of the chart, we see that most people still live on low incomes: 81% of people in the world live on less than $30 a day, or about $900 a month. (written by @MaxCRoser)

Ja tietenkään kaikkien elintaso ei nouse samaa tahtia ja jollakulla se voi laskeakin. Tällaisessa tarkastelussa keskiarvo on kuitenkin demokraattinen työkalu: se ei painota kenenkään köyhyyttä tai rikkautta enemmän kuin jonkun toisen!

Denmark spent decades building nearly 5,000 wind turbines Together, they produced 21.6 TWh in the last 12 months One nuclear plant in Sweden made 23.3 TWh Oh, and nuclear runs 24/7 — wind doesn’t There's one big reason Denmark has some of the most expensive electricity in the world transparency.entsoe.eu/gener… api.energidataservice.dk/dat… eia.gov/electricity/monthly/… iaea.org/publications/16059
Fun fact: Sweden has four nuclear reactors that have each generated more electricity than all Danish wind turbines ever. Forsmark 3 and Oskarshamn 3 started in 1985, the year Denmark banned nuclear. Both still ahead of Denmark’s entire wind fleet.
