This guy built 9 different types of bridges made out of LEGO to demonstrate the complexity of each one. They get better and more advanced each each time. LEGOs can be impressive for those knowing how to use them.

What do you think the main reason extraterrestrial life hasn’t visited us yet?

∫ dx / (x√(x²−a²)) square root in the denominator. product in the denominator. students close the book here. but: x = a·secθ √(x²−a²) → a·tanθ everything cancels. you’re left with (1/a)∫dθ = (1/a) sec⁻¹(x/a) + C a brutal integral. a one-line answer. trig substitution is just pattern recognition in disguise. RT if this belongs in your formula sheet.

Engineering Excellence: The Y-Strainer 🛠️ Great design isn’t just about the finish; it’s about the systems that keep everything running perfectly behind the scenes. The Y-Strainer is a silent guardian in piping systems. Its mission? Trapping debris and sediment to protect expensive pumps and valves from damage. It’s these small technical details that ensure long-term project reliability and peace of mind for our clients.

Most bats can't take flight from the ground, since their wings don't have the necessary strenght, that's why they live perched upside down, they use the momentum from the drop to fly.

I don’t enjoy using X as much anymore.

Hippocrates is often remembered as the father of medicine, but like many early thinkers, his ideas about the body were shaped by observation rather than modern science. When he experienced hair loss himself, he turned to treatments that reflected the medical beliefs of his time. One of the remedies attributed to him was a topical mixture that included opium, horseradish, pigeon droppings, beetroot, and various spices. These ingredients were thought to stimulate the scalp or rebalance bodily “humors,” which were central to ancient Greek medicine. Hippocrates also made an observation that stood out. He noticed that eunuchs rarely experienced baldness. Without understanding hormones, he linked this pattern to the absence of reproductive function and suggested that removing that function could prevent hair loss. This idea shows how early medicine often relied on visible patterns, even if the explanations behind them were incomplete or misguided. Modern research has since shown that hair loss in men is strongly influenced by hormones, particularly dihydrotestosterone (DHT), which affects hair follicles over time. While Hippocrates did not understand the biology behind his observations, his attempt to connect physical traits with internal processes reflects an early step toward scientific thinking. His conclusions were flawed in practice, but the pattern he noticed pointed in the right direction, centuries before endocrinology existed. #hippocrates #WittyHistorian

Ever wonder how a cooling tower works? 🏭 Hot water in → evaporation → cool water out The chimney effect does the heavy lifting in natural draft towers — no fans needed 🌬️ Film fill vs splash fill, natural vs induced draft — it all matters for efficiency ⚙️ #Engineering #MechanicalEngineering #HeatTransfer #EngineerKnow

@pubity Sounds like Indian citizenship scheme

New laws in Japan will make it almost impossible to gain citizenship if you aren't born there. You have to live in Japan for 10 years just to qualify, followed by strict screenings given on a case-by-case basis.

Waste-to-energy (WtE) plants are high-tech "recyclers" that treat non-recyclable trash as a fuel source. Instead of letting garbage rot in a landfill and release methane (a potent greenhouse gas). The 5-Step Transformation * The Pit & the Claw: Garbage trucks dump mixed waste into a massive bunker. A giant crane (the "claw") mixes the trash to ensure a steady burn and feeds it into the combustion chamber. * Controlled Combustion: The waste is burned at temperatures over 850°C (1,560°F). This high heat ensures that most toxic compounds are destroyed immediately. * Steam Generation: The heat from the fire boils water running through pipes in the walls of the furnace, turning it into high-pressure steam. * The Power Spin: This steam is blasted at a turbine, which spins a generator to create electricity. Any leftover steam can be piped into a "District Heating" system to provide hot water and heat directly to nearby buildings. * Flue Gas Scrubbing: Before the smoke leaves the stack, it passes through "scrubbers" and fabric filters that use lime and carbon to neutralize acids and trap 99% of particulates, making the air released cleaner than what many traditional factories emit. The AI Connection: The "Smart" Burner As of 2026, AI has become the primary operator for these plants, making them significantly more efficient: * Fuel Composition Analysis: Because garbage varies (some is wet food waste, some is dry plastic), AI uses computer vision to analyze the "fuel" on the moving grate. It automatically adjusts oxygen levels and burn times to keep the temperature perfectly steady, increasing energy yield by up to 18%. * Predictive Maintenance: AI sensors listen to the vibrations of the steam turbines. By detecting microscopic changes, the AI can predict a mechanical failure months in advance, preventing "blackouts" or expensive emergency repairs. * Emission Forecasting: AI models now predict how weather patterns will disperse the stack's exhaust, allowing the plant to preemptively adjust its scrubbing chemicals to ensure zero impact on local air quality.

At first glance, the firehouse pole looks like a simple, even playful idea. But it actually came from a very practical problem inside early fire stations, where every second mattered and getting to the ground floor quickly could mean the difference between saving a building or losing it. In the late 1800s, many firehouses kept their equipment and horse-drawn engines on the ground floor, while firefighters rested upstairs. The quickest way down was often a narrow spiral staircase, which saved space but slowed movement, especially during emergencies. According to popular stories, these tight staircases also helped prevent horses from wandering upstairs, as animals could become confused or stuck on straight stairways. Whether that happened often is debated, but the design certainly made movement difficult for humans rushing to respond. The solution came in 1878 when a firefighter named David Kenyon in Chicago installed the first fire pole after noticing how fast sailors slid down ship poles. It worked immediately. Firefighters could reach the ground floor in seconds, avoiding crowded stairs and reducing response time. The idea spread quickly across firehouses around the world, turning a simple vertical pole into one of the most iconic features of firefighting history. #historyfacts #WittyHistorian

@pubity They deserve a kit kat break

Thieves in Europe stole a shipment containing 12 tons of Kit-Kat bars, one of the biggest candy heists in history. They stole so much that Nestle has warned of a Kit-Kat shortage in Europe.
