Happy 3²/4²/5² ! Here's a cool fact about a 3-4-5 right triangle: The circle that fits perfectly in a 3-4-5 right triangle has an area of pi square units! Here's why.

One of the coolest math facts that I know is that the only circle that fits perfectly in a 3-4-5 right triangle has an area of pi. Here's how we can prove this.

In a recent video, I showed that in a 3-4-5 right triangle, the radius of the inscribed circle is 1. We can generalize this: in an a-b-c right triangle, the radius of the inscribed circle is (a+b-c)/2. Here's how we know this:

Mathematics, physics. We live in a chaotic, unpredictable universe. This is a grid of 812 double pendulums, each with slightly different initial conditions for the two angles of the pendulum. By Jonathan Nafziger, Used with permission

📁 Terence Tao, Fields Medal mathematician, says mathematics could become AI’s safest and most powerful domain. Language models can be brilliant or completely wrong, but in math every claim is forced through logic and can even be verified by proof assistants. Where other fields struggle with unreliability, mathematics can eliminate the noise and preserve only what is true.

Was Jesus Vegetarian? Jay Dyer Vs Dr Narco He argues "meats means seeds." Kid you not. Lasted 14 mins. As I referenced: 1 Tim. 4:4: "For every creature of God is good, and nothing to be refused, if it be received with thanksgiving: 5 For it is sanctified by the word of God and prayer." The context of 'broma' is flesh meat in 1 Tim. 4.

🎙️Jeremy Scahill on the Tim Dillon Show: “Part of why it’s so damning… the reason we’re at war with Iran right now is because of the way the U.S. political system is arranged… What’s hidden in plain sight is in a way more damning than the Epstein files. It’s that we have a system that produces the kinds of characters that are in power right now.” jeremy scahill | Tim Dillon

Giving a talk in the Stanford University SCIEN seminar this Wednesday (1/3) at 4:30pm: The topic is “normal coordinates”: a shape representation little-used outside of mathematics—but which turns out to have nice applications in geometry processing & learning.

Tim Walz testified yesterday on $2.4 billion in federal fraud. House Oversight Committee. March 4. Rep. Nancy Mace held up a sign. She called it “Minnesota math.” Walz: “I’m not here to be your prop.” Congressional hearings hit different with the right soundtrack.

🚨 FULL CONVERSATION Fields medalist Terry Tao sits down with Math Inc's Jesse Michael Han and Jared Duker Lichtman for a conversation on the future of mathematics. "I got convinced that this was the future of mathematics [...] It's a different style of writing proofs that actually is in some ways easier to read—harder to check by humans, but you see more clearly the inputs and outputs of a proof, which traditional writing often conceals [...] I think the definition of a mathematician will broaden."

Tim Scott: "Inflation ticked up to 4.2%, the highest in 3 years. The trend is not going in the right direction. But one of the things it signals is resiliency in our economy, which is in fact good news. Because of Donald Trump, we have more Americans with more money in their pockets."

A Canadian math education association put “2 + 2 = 4” on a white supremacy slide. In 2022, the Ontario Mathematics Coordinators Association ran a professional development webinar for math teachers across Ontario school boards. The slide was titled “White Supremacy in Math Education.” Under “covert white supremacy” it listed: standardized testing, “I don’t see colour in my math class,” and “Of course math is neutral because 2 + 2 = 4.” Not a fringe blog. Not a parody account. A professional association shaping how math teachers are trained. When the slide went viral in 2023, the OMCA released an official statement confirming that 2 + 2 = 4 is mathematically true — but argued the equation can be “weaponized to uphold bigotry and white supremacy ideology” when used to claim math is politically neutral. Their defense of the slide was the slide. Someone once wrote about a party that demanded citizens believe two and two made five. In 2022, a professional math association wrote a slide that said believing math is neutral is white supremacy. One was fiction. The other was professional development.
