Math is more than arithmetic. How does 1+2+3+... = -1/12? It’s the Riemann Zeta function! Through analytic continuation, we "expand the map" of numbers to find hidden values in infinity that even quantum physics relies on. Absolute magic. #Math

Great to see The Ocean Cleanup getting attention! Just a quick update: as of early 2026 they've already removed over 45 million kg of plastic from rivers and oceans combined — way past the 500k kg mentioned here. The real game-changer now is their river Interceptors. They're deploying them in more cities every month and aim to stop ~1/3 of river plastic flow by 2030. Ocean cleanup is cool, but preventing it from getting there is even smarter.

This is incredible. This machine is capable of cleaning up 100 million kg of plastic ocean waste, and as of 2025, it has already collected about 500,000 kg of plastic. It aims to remove 90% of ocean plastic by 2040.

What's more interesting is that during Mao's rule (mainly due to the Great Leap Forward), 40–80 million people died from famine and poverty, Hitler's regime caused 17–35 million deaths through World War II, and Stalin rounds out the top three with 6–20 million deaths (some sources even go as high as 40 million).

The most mind-blowing fact is that if you center the spiral on 41, you get the longest unbroken diagonal line of consecutive primes — a streak of 40 primes! Plus, this pattern perfectly aligns with quadratic polynomials like n² + n + 41 (Euler's famous prime-generating formula).

Did you know that one of the most important discoveries in mathematical history happened because a scientist was bored during a meeting in 1963? Stanisław Ulam was sitting through a dull lecture when he began doodling on graph paper. He wrote the number 1 in the center, then spiraled outward—2, 3, 4, 5, and so on—simply to pass the time. But then he did something remarkable: he circled all the prime numbers—2, 3, 5, 7, 11, 13... What he saw next was astonishing. The primes were not scattered randomly as everyone had assumed. Instead, they formed striking diagonal lines across the spiral—like hidden highways running through the numbers. This seemed impossible. Prime numbers are supposed to be irregular and unpredictable, yet here they were, aligning in beautiful patterns no one had noticed before. When Ulam showed his discovery to other mathematicians, they were amazed. What began as a simple doodle revealed deep and mysterious structures within numbers—patterns that, even today, we do not fully understand.

Endless loop ...

Exactly, nothing is absolute. Laws are human-made tools that evolve over time—moving from 99% accuracy to 99.999% as society adapts. But they never reach 100%. That's why morality ≠ law. Humanity had a sense of morality long before formal laws even existed. A person can be law-abiding but morally questionable, or vice versa.

@quarksci @stats_feed Americans views on migrants are very positive and all are welcomed to be a part of of the USA. The ongoing debate presently is about illegal immigration. Majority of people feel law abiding citizens are morally good, or bad if breaking them. In most cases, nothing is absolute.

How moral do people think their fellow citizens are? Share of people who say “most people in my country are moral”: 🇨🇦 Canada - 92% 🇮🇩 Indonesia - 92% 🇮🇳 India - 88% 🇸🇪 Sweden - 88% 🇦🇺 Australia - 85% 🇯🇵 Japan - 83% 🇲🇽 Mexico - 83% 🇬🇧 UK - 82% 🇳🇱 Netherlands - 80% 🇰🇷 South Korea - 78% 🇩🇪 Germany - 72% 🇰🇪 Kenya - 72% 🇪🇸 Spain - 71% 🇳🇬 Nigeria - 71% 🇵🇱 Poland - 70% 🇦🇷 Argentina - 70% 🇮🇱 Israel - 68% 🇭🇺 Hungary - 68% 🇿🇦 South Africa - 63% 🇮🇹 Italy - 59% 🇫🇷 France - 55% 🇬🇷 Greece - 55% 🇧🇷 Brazil - 51% 🇹🇷 Türkiye - 51% 🇺🇸 U.S. - 47% Only one country surveyed where a majority think others are NOT moral: 🇺🇸 United States Source: Pew Research Center, spring 2025

@NineOne1987 @stats_feed Fair point, but I don't think divorce is the only cause. Rising fraud and the polarizing views on migrants also play a huge role in how Americans perceive each other's morals.

@quarksci @stats_feed Also when you have 50 percent divorce rate among marriages and 8 out of 10 are filed by women, you can see a large majority of the population would feel others to be not have good morals... Whether it be infidelity or abuse, majority feel breaking a holy vow is morally bad.

@TheSolcrow @SamaHoole Exactly! While our pH is like a scavenger's, our intestinal tract is more like an omnivore's.

@quarksci @SamaHoole Similar to a horse or rabbit then? Also you have to look at intestinal length and fermentation chambers

Stomach acid pH across species: Sheep: 5.0 - dedicated herbivore Horse: 5.5 - dedicated herbivore Gorilla: 4.5 - dedicated herbivore Dog: 2.0 - carnivore Wolf: 2.0 - carnivore Lion: 2.0 - carnivore Human: 1.5 - more acidic than all of them Vulture: 1.0 - obligate scavenger Hyena: 1.5 - bone-crushing scavenger We didn't evolve as herbivores who occasionally ate meat. We evolved as scavengers who moved up the food chain. That pH 1.5 isn't designed to digest salad. It's designed to kill the botulism in a three-day-old carcass. You have the stomach of something that ate whatever was dead and available. Your ancestors were not fussy. They were alive.

Love this one! Fun fact: if you actually calculate the volume of a typical large pizza (say r ≈ 6 inches, h ≈ 0.6 inches), you get roughly π·36·0.6 ≈ 68 cubic inches — which is almost exactly the same volume as a standard 12 oz can of soda. So next time someone says “pizza is just bread”, tell them it’s basically a very flat soda can 🍕🥤

Why pizza is called pizza

Yeah, the pyramid hits hard—wealth is insanely concentrated. Latest data shows the global top 1% (roughly 60 million adults) actually controls about 48% of total household wealth, while the bottom ~82% holds just ~13%. The 4%/5%/90% split is more meme than fact, but the core point stands: a tiny elite owns way more than most realize. Waking up is step one; the real question is what we do with that awareness. Stay sharp.

1% control the world. 4% are puppets. 90% are asleep. 5% know what is going on and are trying to wake up the 90%. The 1% don't want the 5% waking up the 90%.

Crazy how Brasília went from empty savanna to a fully functioning capital in just ~41 months (1956–1960)! Built to open up Brazil’s interior and symbolize progress, its iconic “airplane” layout (fuselage = Monumental Axis, wings = residential sectors) was actually inspired by modernist dreams of flight and globalization post-WWII. Today ~3 million people call the metro area home, though the original Pilot Plan was designed for only ~500k. Still a stunning UNESCO masterpiece.

The biggest city that didn't exist 100 years ago. Brasília, the capital of Brazil, with 3 million inhabitants.

The list assigns Islam Karimov to Uzbekistan despite no notable inventions. Meanwhile, it credits Jabir ibn Hayyan (8th-century chemistry pioneer, distillation/crystallization innovator) to Azerbaijan—despite his life in Kufa/Tus (modern Iraq/Iran), with no historical link to Azerbaijan. Uzbekistan birthplace/region of true global giants: • Al-Khwarizmi (algebra, algorithms; term "algorithm" derives from his name) • Al-Biruni (polymath; astronomy, math, geodesy) • Ibn Sina (Avicenna; Canon of Medicine taught in Europe 500+ years) These shaped world science far more than any modern figure here. Please reconsider for factual accuracy—historical impact > political symbolism

In 2022, Babraham researchers used Yamanaka factors (OSKM) for just 13 days on 50-year-old skin cells → rewound their epigenetic clock by ~30 years! More collagen, faster wound healing, identity preserved. Partial reprogramming could change anti-aging forever. #Longevity #Epigenetics

Great breakdown! One cool extra detail: while hurricanes/typhoons/cyclones are basically identical, the Northwest Pacific (typhoon zone) sees way more of them each year—about 25-30 named storms vs ~10-15 in the Atlantic hurricane basin. That’s why places like the Philippines and Japan get hit so often. Also, fun etymology note: “typhoon” likely comes from the Chinese “tai fung” (大風 = big wind), which fits perfectly.

I never knew the difference between a hurricane, monsoon, cyclone, typhoon, or tornado until I watched this.

Lmao this canal network is peak engineering nightmare 😂 Fun fact: the Strait handles ~20 million barrels/day — roughly 25% of global seaborne oil trade and ~20% of world oil consumption (per IEA 2025 data). Bypass options? Only ~3.5–5.5 mb/d via existing pipelines. Everything else is mountains, geopolitics, or this beautiful madness. Iran basically has a veto on a quarter of the planet’s oil highway. Terrifying when you zoom out.

A realistic plan to bypass the Strait of Hormuz using existing bodies of water

Tricky one! The Mercator projection makes Russia look massive, but population-wise Bangladesh wins here with ~178 million people (2026 est.). Russia ~143M, Ethiopia ~139M, Mexico ~133M. Mind-blowing how a tiny land area can pack in so many people—Bangladesh's density is over 1,300/km²! Maps really mess with our perception sometimes

Kaliningrad (formerly Königsberg) was given to the USSR at the 1945 Potsdam Conference as war reparations after Germany lost ~20 million people in WWII. Almost all Germans were expelled and replaced with Soviet settlers. Today it hosts Russia’s only ice-free Baltic port and a major naval base (including nuclear submarines). Sandwiched between NATO members Poland and Lithuania, its strategic value has only grown. The 1945 borders were never seriously renegotiated — so it remains Russian.

Can someone please explain to me why Russia 🇷🇺 owns this part of Germany 🇩🇪?

True story — that famous 2007 Japanese study showed NK cell activity jumping ~50% after just 2-3 days in the forest, and the boost often lasted 7–30 days. Later research found even a single 2-hour “forest bath” can drop cortisol by ~13–16% and improve mood & focus. Bonus fact: phytoncides (natural oils trees release) seem to be one of the main drivers behind the immune kick. So yeah, trees really are doing free immunotherapy

🚨: Research suggest that just 3 days of camping in the forest can increase the production of cells that kill cancer by more than 50%.
