Can the US build a DJI? We bought a 2019 Mavic Mini and a 2023 Mini 4 Pro, tore them down in our hardware lab, and put them under a bench microscope to find out. What we found: arenaphysica.com/publication….

Greg Brockman says OpenAI pointed Astra at its own systems until it ran out of vulnerabilities to find: "We took 25% of our production engineers and said, 'Sorry, all your projects are on hold. You are now defending. You are now up-leveling our security architecture. You're going to use the models to find all the holes.' And we found a number of serious issues, and we fixed them." "We found some new problems, but eventually it saturated. We basically have found, to our knowledge, all of the P0s, all of the critical problems that Astra is smart enough to find. And of course, there will be a new model, there will be a new round." "You want to be in this tight loop of new cyber capability drops, you deploy it against your systems, you find the new holes, and ideally, you've managed to automate this, what we call defense factory. That's what we're building internally." "There are ideas, for example, formally verifying all of software, that are possible with AI." @gdb @bhorowitz

After years of working in electronics, this feels like a full circle moment. Many late nights later we are releasing Atlas Fields Studios, free for everyone fields-studio.arenaphysica.c… The Fields Studio App lets you explore electromagnetic behavior around PCB designs #buildinpublic

One of the best (and hardest) parts of building a foundation model for electromagnetism is bringing together two very different disciplines: RF engineering and research. Can you guess which design came from our RF engineers? Vote below 👇

Today, we’re proud to unveil Heaviside-1, @arenaphysica's second generation foundation model for electromagnetism. Five months since announcing Heaviside-0, today’s launch marks a critical milestone towards building electromagnetic superintelligence, a foundational intelligence that understands EM across the spectrum and is capable of designing next gen electromagnetically-governed systems, from RF to semiconductors to photonics. Why we’re so excited about Heaviside-1, and what today’s announcement represents: > It’s big: Heaviside-1 is a GPT-2-size model, roughly 10x the size of Heaviside-0 and trained on 250k unique designs with >500B unique EM field samples > It’s fast: It generates predictions with 5 orders of magnitude acceleration relative to commercial solvers, with under 1dB of accuracy > Full-3D Encoding: Heaviside-1 natively encodes 3D structures, their material properties, and excitation patterns as input, a major step towards generalizability across design spaces > Understands the underlying physics primitive: Heaviside-1 generates full-3D near-fields at arbitrary locations, not just downstream quantities like s-parameters > Generalization: Most importantly, our bet on fields as the primitive for Heaviside-1 generalizes OOD, proving that it’s learning real EM physics. Heaviside-1 generalizes outside of distribution incredibly well and better than Heaviside-0, down to 0.53 dB s-parameter error from 0.99 dB on Heaviside-0. Read more about Heaviside-1 and the work that went into it in this write-up by our research team, @m__frei, @chris_m_bryant, @nathanmirman, @HaoLiu69889370, Tommaso, Roberto, Ruichen, Noah, Boyuan, and @Trevs_Dev, and our RF team @hk2532_harish, @anrfic, @suyangcn and Zhaoji. arenaphysica.com/publication…

interesting... a car is just a concept. looking at the "physics" stats bare like this is interesting. very intriguing spline reference + momentum control system instead of tire physics It's essentially a brick running on vaguely invisible rail

Palantir invented the forward deployed engineer. But what happens when you put FDE in contact with deep science and hardware problems? You create mutants. We are those mutants. As we forward deploy around the world, we’ve had the privilege of working alongside our customers, obsessing over the applied science and engineering work required to solve the hard problems that stand between their ambition and the built world we all desire. Our Feynman-inspired lecture series and early research content were an attempt to share just a sliver of the magic we experience every day in the field. On the back of the overwhelming response we’ve gotten from our fellow misfits, we’re turning what started as a couple of side quests into a commitment to create more technical content about nerds, by nerds, solving science and engineering problems. Introducing Transmissions, @arenaphysica's science studio. If these Transmissions speak to you, or if forward deploying to nerd out like this seems fun, I’m hiring Forward Deployed Engineers.
