Cams act as the mechanical memory of the machine.. Jacques de Vaucanson realized that by placing hundreds of tiny, precisely shaped cams onto a single rotating cylinder , he could create a complex mechanical code I wish we had been introduced to cams differently back in college

This is a 1868-founded German legend: the Heidenreich & Harbeck straight bevel gear generator, built in 1959. Instead of digital code, this machine is "programmed" by physical gears, rotating cams, and levers. As the dual cutting blades slide back and forth, the machine rolls the metal blank against them, carving a perfect, tapering curve onto each tooth with micron-level precision.

I think onboard cameras are neat so I made a compilation video of 50 different angles that have been used in NASCAR TV Foot cams, suspension cams, driveshaft cams, ones on the passenger door, ones on the spoiler, ones on the hood, one near the jack post

In July 2011, Professor Hideyuki Sawada from Kagawa University in Japan demonstrated a robot that produced sound by physically mimicking human anatomy. Instead of playing a digital recording through a speaker, the machine used an air pump to act as lungs, artificial vocal cords to create vibrations, and a mechanical tongue and lips to physically shape the air into words.

🚨#BREAKING: A former Air Force engineer in Virginia has been arrested after he allegedly damaged / destroyed over a dozen Flock cameras. When asked why, he said the Flock cams were, "unconstitutional and a violation of my and others’ Fourth Amendment rights." He allegedly tossed them off major highways where they shattered. Police caught the former engineer by using the very Flock cams he was destroying to track him down.

I've been thinking about steampunk How most designs suck because instead of actually embracing the mechanical principles they just put rust on sci-fi tech and call it a day. So i made a REAL mechanical Dragoon to demonstrate what the genre could be if it wasn't crewed by hacks

Former immigration judge says he could not find evidence that a single person he ordered removed from our country HAD ACTUALLY BEEN REMOVED by the Biden Admin. “I also found that when I was an immigration judge, I later tried to determine how many of the people that I had ordered removed that their removal had actually been effectuated from the United States, which was something that was fairly easy to do under prior administrations. “But I could not substantiate that a single individual that I had entered an order of removal against had actually been removed by this administration. “It's shocking.”

In a highly competitive global economy, we need the best educated workforce in the world. That means that all of our young people, regardless of income, have the opportunity to get a free college education. That’s why I’ve introduced my College for All Act.

I’m happy to announce that the newest CNC machine that we built in our facility has broken our previous record of 779 pcs/minute. Our fourth and the latest machine is now manufacturing precision springs at 882 pcs/minute. If only I could tell you the amount of mechanical precision the components require to achieve this feat. Onwards and upwards! 🚀

It was great to pick up a wildcat on one of our trail cams. This male cat was released several months ago in Speyside as part of the Saving Wildcats (#SWAforLIFE) project. In Sept this year, he had an amazing journey travelling over the Cairngorms to reach Mar Lodge.

What seemed like an intractable problem is now possible: To design proteins with a specified nonlinear mechanical response, capturing complex folding and unfolding mechanisms in singe and few-shot computations. We present ForceGen, an end-to-end algorithm for de novo protein generation based on nonlinear mechanical unfolding responses. Rooted in the physics of protein mechanics, this generative strategy provides a powerful way to design new proteins rapidly, including exquisite and rapid predictions about their dynamical behavior. Proteins, like any other mechanical object, respond to forces in peculiar ways. Think of the different response you'd get from pulling on a steel cable versus pulling on a rubber band, or the difference between honey and glass. Now, we can design proteins with a set of desirable mechanical characteristics, with applications from health to sustainable plastics. The key to solving this problem was to integrate a protein language model with denoising diffusion methods, and using accurate atomistic-level physical simulation data to endow the model a first-principles understanding. ForceGen can solve both forward and inverse tasks: In the forward task, we can predict how stable a protein is, how it will unfold and what the forces involved are, all given just the sequence of amino acids. In the inverse task, we can design new proteins that meet complex nonlinear mechanical signature targets. Read the paper, led by LAMM@MIT postdoc Bo Ni, published in Science Advances: Why do we care about the mechanics of proteins? The mechanics of proteins are critical elements of many living systems - as evidenced in many studies of mechanobiology. Through evolution, nature has presented a set of remarkable protein materials with unique mechanical functions like elastins, silks, keratins or collagens that play crucial roles in biology. However, going beyond natural designs to discover proteins that meet specified mechanical properties remains challenging. So far, the only way to do this was to use existing evolutionary concepts or to manually alter proteins. With our new generative model we can directly design proteins to meet complex nonlinear mechanical property-design objectives. ForceGen leverages deep knowledge on protein sequences from a pretrained protein language model and maps mechanical unfolding responses to create proteins. Via full-atom molecular simulations for direct validation from physical and chemical principles, we demonstrate that the designed proteins are de novo, and fulfill the targeted mechanical properties, including unfolding energy and mechanical strength, and a detailed unfolding force-separation curves. ForceGen offers rapid pathways to explore the enormous mechanobiological protein sequence space unconstrained by biological synthesis, to enable the discovery of new protein materials with superior mechanical properties.

🇺🇸 NVIDIA CEO JENSEN HUANG: WE HAD TO INVENT THE COMPUTER BEFORE THE PROBLEM EXISTED Jensen reflected on Nvidia’s early days, revealing how the company’s mission in 1993 seemed almost impossible, building a computer for problems that didn’t yet exist. He said they had to “create the problem” before they could solve it, a gamble that shaped modern computing: “When Nvidia started in 1993, we were trying to create this new computing approach. The question is, what’s the killer app? The company wanted to create a new type of computer that could solve problems normal computers couldn’t. But the applications that existed in 1993 were ones that normal computers could solve. We had a mission statement for a company that had no chance of success. I didn’t know that in 1993. It just sounded like a good idea.” Source: Joe Rogan

Mollie Hemingway delivers an absolutely masterful defense of Matt Gaetz as AG. For eight years, we haven't had a Department of Justice, we've had a Department of Injustice, and too few of our leaders in DC had the spine to fight back. Gaetz has enemies in DC precisely because he didn't back down from the toughest fights. He is the warrior we need to set things right. 🔥🔥
