Elon Musk: We've designed Optimus from physics first principles. “We could not actually buy the actuators for any amount of money. They simply didn't exist. Even though there are 10,000-20,000 electric motors out there of various sizes and shapes, we've had to design every electric motor, gearbox and the... show more

There's something very funny about Optimus explaining first principles. A humanoid robot calmly describing the mindset that helped create rockets, EVs, factories, and eventually itself. First principles thinking is basically Elon refusing to accept the “because that’s how it’s always done” answer. At Tesla and SpaceX, the question is not only how to make the old thing better. It is whether the old thing should exist in that form at all. Why throw away a rocket booster if the physics says it can come back? Why build an EV like a compliance car if batteries, software, motors, and factories can be redesigned around performance and scale? They strip the problem down to physics, materials, cost, and function, then rebuild upward from what is actually true. Very useful for building things that did not exist before.

🤖 Tesla's Optimus Gen 3 hand patent reveals tendon/cable-driven fingers - actuators mounted in the forearm, not the hand • Cable routing transmits force from forearm motors to each finger • Forearm placement eliminates the distal mass penalty that compounds up the kinematic chain • Elon cited the hand and forearm as Optimus' hardest unsolved mechanical challenge Moving motors out of the fingers is the mechanism that lets Gen 3 grip at high force without the arm fighting its own inertia on every move.

Filipino pop group SB19 recently made a surprise stop in Hong Kong and held their first concert there at MacPherson. Since the five heartthrobs flew in, we of course arranged an interview and even helped A’TIN score some perks! Josh, Pablo, Ken, Justin, and Stell really know how to melt fans’ hearts — they went all out, throwing themselves into the tasks with full-on charm, and each of them switched to turbo “electric” mode. (Friendly reminder) beware — you might just faint from the sparks! (Google translation) Watch here: #SimulaAtWakas #SB19 #SB19SaW #SaWWorldTour #SaWWorldTourHongKong

We released physics-intern: a simple harness for science problems! It gets models like Gemini 3.1 Pro to go from 17.7 -> 31.4, thus beating GPT 5.5 Pro. The physics-intern harness can wrap any model and via dedicated subagent boost the performance of the vanilla reasoning models. While I think more and more of these harness capability gains will be absorbed into the models (like prompting tricks disappeared over time) there is a lot to be gained right now by building good scaffolds for those models and integrating tools well. Interestingly, the exception we found that GPT 5.5 Pro actually didn't benefit from the physics-intern harness! Read more about it here: PS: I think the Harness[Model] notation is kind of nice.

Actually Japanese fans have a culture of being respectful and very strict about following rules and it’s so evident in all the videos. They barely even used their phones and they are really enjoying that moment with boys. Jcoers actually killed it 🤌🏻 They should give fans from each country priority access to tickets on the first day then open sales to everyone else... If coers from other countries are going to Japan PYPD in future either respect and follow their culture or simply don't go there

Update on LAT Aerospace Our first uSTOL technology demonstrator is ready. Today, we have a fully-electric, fixed-wing UAV, built from scratch and almost ready for flight. To make this possible in just a few months, we built our entire flight lab from scratch. Every bench, every tool, every fixture designed to push the aircraft closer to flight every single day. This aircraft is designed to takeoff in 40 meters (thanks to a massive CL of 5 which is more than 2x of what you see on most aircraft). Endurance of 60 minutes. With a range of being able to cruise autonomously from Mumbai to Pune. Ground rolls done. As I type this, we are pushing hard to get the bird in the air. Hopefully it doesn't blow up. Either way, I promise videos of our attempt sometime over the next few weeks. We have learnt so much over the last few months, and I am sure that there are a lot of hard learnings yet in store for us. Our research on hybrid-electric propulsion is already in full swing, and we’ve also started building a team to begin development on our own gas turbine engines. This is one of the hardest engineering challenges possible. Our team is relentlessly at it to make this a reality before the turn of this decade.

Elon Musk: Once you lose freedom of speech you don’t get it back. “Free speech and a level playing field, that’s the bedrock of a functioning democracy. That’s why the First Amendment was the first thing they did. Where they came from there wasn’t freedom of speech, and once you lose freedom of speech you don’t get it back. So that’s why we must protect it at all costs.” Source: Morgan Stanley TMT Conference, March 7, 2023

🚨 BREAKING: We just broke one of superconductivity’s biggest limits… with a lightweight element. No heavy exotic materials. No extreme redesign of physics. Just 3 atomic layers of gallium… sandwiched between graphene and silicon carbide. And suddenly Superconductivity survives strong magnetic fields Beyond the expected physical limit In a system that shouldn’t be able to do it Why? Because the interface changes everything. The electrons don’t behave normally anymore. Their spin locks in place… protecting the flow. Meaning: No resistance. Even when physics says it should fail. Now think bigger What if materials aren’t defined by what they are. but by how they’re structured at the smallest scale? What else could we unlock just by changing the layers? The real question is How many “limits” in physics… are actually just design problems? What other possibilities are out there? Follow me this is where physics gets real.

We've got 24,000,000 pounds of waste to pick up every day, and, WE ARE DOING IT. Today is Thursday and we are collecting Thursday trash and compost today (though maybe not at the same time that you usually receive collection). Recycling collection may be a little behind. Snow operations continue, too. We continue to plow, haul, and clear snow from all over – and have now melted 215,000,000 pounds of it!

Today, we’re pulling back more of the curtain on the in-house teams and technology that will bring the Ford Universal Electric Vehicle to life. More than half of our aero team came from the Formula 1 world, where air is either your greatest ally or most punishing enemy - and every curve matters. From the sculpted roofline to the underbody, our teams are chasing physics in search of longer range and lower cost for our customers. Our new mid-size electric truck’s aerodynamic efficiency is more than 15% better than any other pickup truck on the market today. “To the air, it’s no longer a truck”. From a zonal architecture and 48V low-voltage system, to the new in-house E-Box, and smaller and lighter wire harnesses, the team is obsessing over every detail with UEV. Our aim is to have a family of vehicles that we expect to compete on price with the best in the world, including gas vehicles. And they will be FUN to drive!

Every year, the best young engineers in the world compete at the FIRST Robotics Competition. This year, a team coached by one of our own came out on top. Jonathan Mi, an electrical design engineer at Shield AI, mentored Team 4414, HighTide, who took first place across 93,000 students, 3,700 teams, and 35 countries. They designed, programmed, and built their robot from scratch. Watch what it does. The strongest engineers build up everyone around them. That's who we hire. Congrats to HighTide, and when graduation comes, you know where to find us! Autonomy for the world. The greatest victory requires no war.

HYPOCRITE OF THE WEEK Only a leftist hypocrite would vote to prevent small businesses from using their own money to buy a few sandwiches and claim it as a legitimate business expense, while she herself was systematically rorting taxpayers through her travel allowances to the tune of $10,000. If she had any decency, Anika Wells would paid back the money and resigned today. But she hopes there are enough stupid Labor voters out there who will re-elect her.

🚨 MERCEDES JUST PUT A MOTOR ONLY 8 CM THICK INTO A CAR THAT CAN HIT 62 MPH IN 2.1 SECONDS. Instead of conventional radial flux motors, Mercedes is betting big on axial flux technology. In these motors, the electromagnetic force flows parallel to the axle, allowing two magnetic rotors to sandwich a central stator in a flat, disc-like layout. The result is dramatically smaller and more powerful. The front motor in the new all-electric Mercedes-AMG GT 4-door Coupe is just 9 cm wide. The rear motors are even thinner at roughly 8 cm each. Despite their tiny size, they help launch the heavy performance car from 0-62 mph in just 2.1 seconds, with a top speed of up to 186 mph. Why this matters: • Axial flux motors are significantly more power-dense and can be up to 50% lighter than traditional designs • Their extreme thinness frees up packaging space in the vehicle for better weight distribution, aerodynamics, or interior room • Mercedes acquired YASA in 2021 and has spent years developing the complex manufacturing processes needed to build them at scale • The technology is debuting in a high-performance AMG model, showing Mercedes is serious about using it in its most demanding cars The deeper implication: While most of the EV conversation focuses on batteries and software, the electric motor itself is undergoing a quiet revolution. Axial flux designs have long been seen as theoretically superior but extremely difficult to manufacture at scale. By solving the production challenges and putting these motors into a real high-performance car, Mercedes is pushing the entire industry forward. The next generation of electric performance cars may not just have bigger batteries they may have fundamentally better motors. We’re watching the physical hardware of EVs evolve as dramatically as the software has. How important do you think motor technology (rather than just battery size) will be for the future of electric performance cars?
