@garyseconomics I just love how he gets under the skin of everyone here, and they all attack the Gary and not his ideas. That means he's doing a great job. Thank you man!!

If the claim is that Finland has the best education system, the data matters. And the data doesn't support this claim. Here are some of the things I'm hearing from folks who do not want to believe the data: ▶️ “All countries are declining” — ok, but their programs aren't being sold as the best ▶️“PISA isn’t reliable” — perhaps, but then why is PISA being used as supposed evidence that Finland is great?(& the PISA data doesn't even support this) ▶️“East Asia is different: kids are in tutoring all day” — that has nothing to do with Finland These arguments don’t refute the point at all. Sometimes the people making these arguments have even written books on the supposed success of Finland's education system. That's telling.

The most productive mathematician who ever lived. Leonhard Euler. Born April 15, 1707. His collected works fill between 60 and 80 large volumes. The project to publish them all began in 1911. It is still ongoing. Laplace told his students: "Read Euler, read Euler, he is the master of us all." What he actually built: 1/. The language of all mathematics Every formula you have ever written uses Euler's notation. He introduced: e - the base of the natural logarithm i - the imaginary unit, √−1 f(x) — the modern notation for a mathematical function Σ — sigma notation for summation π - he didn't invent pi, but popularized it. If you have ever taken a mathematics course, you have been writing in Euler's handwriting. 2/. Graph theory - from a bridge puzzle In 1735, the citizens of Königsberg had a puzzle. Their city sat on the banks of the Pregel River, connected by seven bridges. Could you walk through the city crossing each bridge exactly once? Euler stripped away everything irrelevant - streets, distances, geography, and kept only the connections. Landmasses became nodes. Bridges became edges. He proved the walk was impossible because all four landmasses had an odd number of bridges. A valid Eulerian path requires exactly zero or two nodes of odd degree. Königsberg had four. His 1736 paper Solutio problematis ad geometriam situs pertinentis is the founding document of graph theory. He was almost apologetic about it, writing to a colleague that it "bore little relationship to mathematics." He was spectacularly wrong. That paper today underlies modern network and routing systems. 3/. Euler's Formula e^(ix) = cos x + i sin x This single equation unifies exponential functions and trigonometry through complex numbers. Richard Feynman called it "our jewel" and "the most remarkable formula in mathematics." When x = π, it produces: e^(iπ) + 1 = 0 Euler's Identity. Five fundamental constants - e, i, π, 1, 0 - united in a single equation using only addition, multiplication, and exponentiation. Each exactly once. In 2004, Physics World readers voted it the greatest equation ever written. A 2014 neuroscience study found it activates the same region of the brain as great music or art. Benjamin Peirce said of it: "Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don't know what it means. But we have proved it, and therefore we know it must be the truth." 4/. Euler's Formula for Polyhedra V − E + F = 2 For any convex polyhedron: vertices minus edges plus faces always equals 2. A cube: 8 − 12 + 6 = 2. A tetrahedron: 4 − 6 + 4 = 2. Always. This result helped lay the foundation of topology, the mathematics of shape and connectivity that now underlies data analysis, neural network geometry, and computational mesh processing. 5/. The output From 1725 to 1783, Euler averaged 800 pages of mathematics per year. He was completely blind for the last 17 years of his life. His output increased. In 1775, totally blind - he produced on average one mathematical paper per week. Estimated to have authored roughly a third of all mathematical output of the 18th century. One man. One third. Where Euler lives in the systems you build today: e^(ix) = cos x + i sin x → Fourier transforms → signal processing → audio AI, image compression, every frequency-domain operation Graph theory → network routing, GPS, social graphs, recommendation engines, transformer attention patterns e → sigmoid, softmax, cross-entropy loss - every neural network activation and loss function Σ → the notation inside every gradient descent update ever written V − E + F = 2 → topological data analysis, mesh processing, graph neural networks f(x) → the notation of every function in every codebase ever written 319 years later. The language of mathematics is still his.

Einstein developed his theory of relativity, and in response, a book titled “One Hundred Authors Against Einstein” was published. His reply was sharp and elegant: “If I were wrong, one would have been enough—why one hundred?” That’s the nature of facts. If something is truly false, it only takes a single valid counterexample to disprove it. Facts are not decided by numbers or authority; they are tested, questioned, and open to verification. They exist in the public domain, where anyone can examine and challenge them. You don’t accept something as a fact simply because an authority claims it to be true. For example, saying “I believe the Earth is flat because my religious book says so” is not a scientific argument. It’s a matter of belief, not evidence. While faith deserves respect, it is not the process by which facts are established. Facts are earned through evidence, testing, and the ability to withstand doubt.

“We are all alone, born alone, die alone, and—in spite of True Romance magazines—we shall all someday look back on our lives and see that, in spite of our company, we were alone the whole way. I do not say lonely—at least, not all the time—but essentially, and finally, alone. This is what makes your self-respect so important, and I don't see how you can respect yourself if you must look in the hearts and minds of others for your happiness.” — Hunter S. Thompson

En 1973, se encontraron en México dos gigantes: Borges y Rulfo. Esta fue su conversación: R: Maestro, soy yo, Rulfo. Qué bueno que ya llegó. Usted sabe cómo lo estimamos y lo admiramos. B: Finalmente, Rulfo. Ya no puedo ver a un país, pero lo puedo escuchar. B: Y escucho tanta amabilidad. Ya había olvidado la verdadera dimensión de esta gran costumbre. Pero no me llame Borges y menos "maestro", dígame Jorge Luis. R: Qué amable. Usted dígame entonces Juan. B: Le voy a ser sincero. Me gusta más Juan que Jorge Luis, con sus cuatro letras tan breves y tan definitivas. La brevedad ha sido siempre una de mis predilecciones. R: No, eso sí que no. Juan, cualquiera, pero Jorge Luis, sólo Borges. B: Usted tan atento como siempre. Dígame, ¿cómo ha estado últimamente? R: ¿Yo? Pues muriéndome, muriéndome por ahí. B: Entonces no le ha ido tan mal. R: ¿Cómo así? B: Imagínese, don Juan, lo desdichado que seríamos si fuéramos inmortales. R: Sí, verdad. Después anda uno por ahí muerto haciendo como si estuviera uno vivo. B: Le voy a confesar un secreto. Mi abuelo, decía que no se llamaba Borges, que su nombre verdadero, era otro secreto. Sospecho que se llamaba Pedro Páramo. Yo entonces soy una reedición de lo que usted escribió sobre los de Comala. R: Ahora si, ya me puedo morir en serio.

I’m building a corner of the internet for people who feel like they don’t quite fit anywhere else. The overthinkers. The trauma survivors. The neurodivergent minds. The ones who feel deeply. You don’t need to mask here. You don’t need to be “fixed.” Just come as you are. Follow, reply, connect. Let’s make this space feel a little less lonely.

@trose183244 @JamesTate121

@JamesTate121 G'day fucker. Take the US out of the way and you're praying to Allah. Yeah we have some problems but they'll soon be fixed. No more propping up all of you needy shits. That's because of the Non-politician running the show.

Too on point not to share, “Aussie reply to Trump rant about NATO not being there for us. Mate. You run a country with 600,000 homeless people sleeping on the street tonight. A country where 40% of adults can't cover a $400 emergency without borrowing money. A country where insulin costs more than a car payment and people are rationing it to survive. A country where medical debt is the number 1 cause of bankruptcy. A country where women are dying in hospital car parks because doctors are too scared of abortion laws to treat a miscarriage. You lock up more of your own citizens than any nation on earth. More than China. More than Russia. More than North Korea. The land of the free has 2 million people in cages, and a quarter of them haven't even been convicted of anything. They're just too poor to make bail. Your life expectancy is going backwards. You're the only developed nation where that's happening. Your infant mortality rate is worse than Cuba's. Your kids do active shooter drills between maths and English while you sell the gunmaker's stock to your mates. Your minimum wage hasn't moved in 15 years. You've got teachers working 2 jobs and veterans sleeping under bridges and you just spent a trillion dollars flattening a country that didn't attack you. And you’ve got a convicted felon, adjudicating raping, paedophile protecting, porn star shagging insurrectionist running the biggest dumpster fire war campaign since the Taliban thanked you very much for losing again. And you're calling Greenland poorly run? Greenland has universal healthcare. Free education. One of the lowest incarceration rates in the world. Nobody goes bankrupt there because they got sick. Nobody dies in a waiting room because their insurance said no. "NATO wasn't there when we needed them." When exactly was that, champ? September 11? Because NATO invoked Article 5 for the first and only time in history FOR YOU. Soldiers from dozens of countries deployed, fought, bled, and died in Afghanistan FOR YOU. Australia wasn't even in NATO and we still showed up. For 20 years. And you pulled out at 2am without telling anyone and left them to deal with the mess. So maybe before you start calling other countries poorly run, have a look at your own backyard, you spray-tanned aluminium siding salesman. The only thing poorly run in this picture is your fucking mouth. Credit (borrowed from) Jim Scroggins - original author 📷 unknown”

@adamboxer1 I've read it, and I agree with you that only AFTER the explanation should we talk about etymology and definitions. But, sometimes, the name itself contains the definition: equilateral triangle. This one works pretty well in Spanish talking countries because "lateral=lado=side".

I predict nobody will read this post. Too nerdy, too niche.

The word "photosynthesis" comes from Greek words meaning "light" and "making" So, photosynthesis means "using light to make things" That's cool. But what? And who? Who is doing the making? What are they making? It's plants? How do you know? They "make" glucose? How do we know? They also "make" oxygen? Great, how do we know? From what reactants? Where in the cell? Knowing the origins of the term "photosynthesis" tells you very very little about what the process actually is. When I say that etymology and morphology have limited explanatory and predictive power, that's what I mean. Just knowing "using light to make things" could also indicate a solar cell, or a magnifying glass or the production of vitamin D in our skin. So sure, use it as a curiosity. It's interesting for sure. The scientists involved fashioned the word that way for a reason. But it doesn't actually *help* you understand what photosynthesis is.

The engineer who believed he was a mathematician is now facing the truth.
