Bacteria move around using a molecular machine called the... flagellar motor that rotates faster than the flywheel of a race car engine and switches directions in an instant. After 50 yrs, scientists have finally figured out how it works. “My lifelong quest is now fulfilled.” Link⤵️show more

Mike Joy, Clint Bowyer, and Kevin Harvick even called... out Tyler Reddick and 23XI for running an 850hp motor in the first 750hp race. #NASCAR (pulling 4 car lengths in a 1500ft roll race is more than 100hp too, btw)show more

Scientists are baffled by this. The Bacterial Flagellum is... composed of 20-30 unique parts. Combined, they total over 30,000 parts that make this little motor run. It can hit rotation speeds of up to 100,000 RPM, then stop & reverse direction in a quarter of a turn. It can propel a bacteria up to 20 lengths per second, which when scaled up is about equal to 225mph in a car. But this motor only works when all those parts are perfectly engineered and working together. Take away just one of those 30 pieces, and it stops functioning. That means it can't evolve gradually. None of the pieces do anything outside the system, and the system only works with all the pieces. Bacteria require this motor to move - without it, they would quickly die. How can anyone see something like and still deny that Life is Divinely Designed?show more

The hardest part of V14 to explain to people... is just how locked in and responsive it is. There is a step change here vs V13. The car is aware and calculating future moves so insanely fast. In this video, watch the moment my speedometer goes from 70 to 69mph. It recognizes the signaling of vehicle in the right lane, and before it even begins its slide into our lane, FSD is slowing to prepare its next move. It’s hard to explain this because you have to be in the car to feel how quickly the car shows you through movement and speed change that it is aware of what’s happening. I felt it even before you see the speedometer move. It’s almost instant. Way faster than humans and V13.show more

🚨 Elon Musk’s SpaceX is crashing faster than Meta... did after its IPO. $SPCX has collapsed from $225.64 to below $110. That’s more than 51% wiped out in just six weeks. Back in 2012, $META fell around 61%. But it took nearly three and a half months. SpaceX is moving faster. Most people see a failed IPO. I see panic accelerating before the real opportunity appears. Keep in mind: I’ve called every major $SPX selloff, 2025 $BTC ATH and move from $126K → $60K I was one of the only people who called the top in October, and I’ll do it again, that’s literally my job. If you still haven’t followed me, you’ll regret it.show more

Visited Chicago for a few days and had a... great time. Was hoping to write a tweet about how safe it is and how its reputation is undeserved. Then on the walk home on the final night, River North area from Mom’s Place around 2:30am, a black guy rapidly approached my friend and I asking about subway directions. I figured something was up since I assume the subway doesn’t run at that hour. As we walked faster, we saw two other guys at the corner staring at us, probably accomplices. “Be prepared to run,” my friend said. We must have walked faster enough, or maybe we misread the situation, but I won’t go around saying “Chicago is so safe!” Rather, be vigilant and you’ll have a good time. Still love the city.show more

I can't believe how good this turned out. Recently,... I put out my first physics paper proposing that life and the universe might be the result of a law governing how oscillators sync up and couple together. I find it beautiful, awe-inspiring, and deeply meaningful. It aligns with how I have always seen the world. It suggests that there is an arrow of negative entropy, a law governing how life forms in all of its complexity. Learning about it is intimidating. I am self-taught, and have struggled for months to understand and articulate the core concepts and framework. After I put out the paper, I was challenged by Danielle Fong 🔆 to make an 'explorable explanation'. A guide you can walk through, and which will hold your hand through each concept, equation, and principle. It was amazing to make. In fact, I plan to make many more covering the wide range of topics I have been researching and exploring. Both to help me, and because I believe that this is something the world needs right now.

That’s insane! 🤯 A student built an acoustic levitation... divide with an Arduino board. He built it using an Arduino Nano, a motor driver, and 60 ultrasonic transducers that can levitate low-density objects in place indefinitely. The transducers send out 40 kHz waves that create standing waves. The interference pattern produces nulls that trap objects. High-pressure areas form below and above the object, locking it in the low-pressure area between them. The transducers produce two sound waves moving in opposing directions at the same frequency and amplitude. The effect is that the low-pressure areas don't appear to move, like whipping a rope from both ends and having the wave meet in the middle. Sound waves are oscillating at high and low pressures. By creating a sound wave that doesn't move forward (a standing wave), you create areas of constant pressure. 🔉 Objects get trapped in the null points between high-pressure zones. The craziest part is that this was made more than 7 years ago! DIY levitation 😮💨 Reddit link: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →show more

An airplane radial engine is a powerful internal combustion... engine where cylinders are arranged in a circle around a central crankshaft, resembling the spokes of a wheel. Renowned for their exceptional power-to-weight ratio and reliable air cooling, they were the dominant powerhouses of early aviation and World War II. An aeroplane radial engine operates by converting fuel into mechanical rotation through a unique circular piston arrangement. The cylinders are positioned in a circle around a central crankcase, resembling the spokes of a wheel. Inside the hub, only one "master" connecting rod attaches directly to the crankshaft, while all other rods anchor to the base of that master rod. As fuel ignites inside the cylinders, the pistons fire in a specific "skip-one" sequence-such as 1, 3, 5, 7, 9, 2, 4, 6, 8-to distribute power evenly around the hub. This sequential pushing motion turns the master rod assembly, which rotates the crankshaft and spins the aircraft propeller. Finally, because the cylinders face forward into the oncoming wind, the engine cools itself naturally using direct airflow instead of heavy liquid radiators.show more

The VR6 engine was born out of a packaging... problem. VW's engineers needed a six-cylinder that could fit transversely in a front-wheel drive Golf engine bay. Something a conventional V6 with cylinder banks spread 90 degrees could never do. The solution was a narrow-angle 15-degree configuration with a single cylinder head shared across all six cylinders, making it barely wider than a four cylinder. The MK3 Golf VR6 was the first car to receive it in the Golf family 2.8L, 174 HP, 235 Nm, 0-100 km/h in around 7 seconds, and a sound unlike anything else in a hatchback body. Not the fastest car of its era. The most characterful one in its class without question. That engine went on to power the Corrado, the Passat, and eventually the Phaeton and even some Porsche models. This example here is the GTI VR6 and the VR6 produces 201 hp, looks like a lot of fun.show more

The life of a guy who tried to mine... Bitcoin at home: • Watched one YouTube video and said "how hard can it be" • Bought an S19 off some guy on Telegram (receipt was a thumbs up emoji) • Plugged it into a regular outlet and tripped every breaker in the house within 11 seconds • Wife asked "what is that noise" approximately 47 times in the first hour • Moved it to the garage in January. Garage is now 104 degrees. In Iowa. • Electric bill went from $180 to $520. Called the utility company thinking it was a mistake. It was not a mistake. • Dog refuses to go in the garage • Kids think there's a jet engine in the house • Machine went down at 3 AM. Googled "ASIC repair near me." Results: pain. • Shipped it to some repair place in Shenzhen. Got it back 11 weeks later. Different machine. Probably. • Calculated actual profit after power, repairs, and the marriage counseling. Net result: negative. • Finally called a hosting company • Now pays $0.065/kWh, sleeps through the night, and hasn't touched a circuit breaker since • Wife talks to him again • Dog came back inside There are two types of miners. The ones doing it at home. And the ones who used to.show more

Trump says people don't want Electric Cars and they... "don't go far, and that we have a thing called "gasoline". Some FACTS: - We also have a thing called electricity. - Solar and wind power generation is greater than coal generation in the US. - My Tesla can go 375 miles without a charge. - More EVs are made by a US Company, Tesla, than any other company in the world. - Teslas are just as affordable as combustion engine vehicles when you factor in fuel costs. - EV and Battery technologies are rapidly progressing. This means faster charging, longer range, cheaper prices, and more efficient vehicles.show more

Shawty Lo In 2008 Said T.I. Was Ducking Smoke... From 50 Cent 👀 Back in 2008, Shawty Lo had his back and forth with T.I. and 50 Cent went at T.I. around the same time too after he was caught with 12 machine guns and only served 1 Year of Prison for it. 50 Cent at that time questioned how T.I. only got 1 year after being caught with so many guns. He even dropped a G-Unit track titled 'You So Tough' calling out T.I. for being a rat. Shawty Lo back then called T.I. out for ducking the smoke with 50 Cent. (SKEETV / YouTube)show more
