Today, we're announcing Heaviside, our foundation model for electromagnetism.

Trained on tens of millions of designs and over 20 years of proprietary simulation data, Heaviside predicts electromagnetic behavior from geometry in 13ms, which is 800,000x faster than a commercial solver.

Heaviside is not a language model, and it’s not a surrogate model. Heaviside marks a new class of foundation model for physics which understands the fundamental relationships between materials, the geometries and the electromagnetic fields they generate.

We’re releasing a research preview of Heaviside in Atlas RF Studio, an interactive agentic sandbox where you describe the EM behavior you want and the model generates the physical structure that produces it.

@arenaphysica , we believe the implications of this class of model extend well beyond RF, as the frontier of exquisite hardware is electromagnetically-governed: wireless communication, radar, power delivery, high-speed computing, and the interconnects inside every chip on earth.

In the months ahead, we’re excited to scale up Heaviside to broader frequency ranges, design spaces, and to support silicon-level designs, and deploy it with our closest partners and collaborators in service of their biggest design challenges.

If you’ve read our thesis, this is just Step 2 in our pursuit of electromagnetic superintelligence.

Today, we're introducing @arenaphysica, the electromagnetic superintelligence company.

Our mission: accelerate the design, development, and deployment of the devices that will sense, communicate, compute, and actuate in the future of autonomy, with EMSI.

For years, we’ve been building a new type of company in the shadows with our partners and collaborators.

We're proud to share that we’ve deploying EMSI with @AMD in AI compute, @anduriltech in defense technology, and @SiversSemicond in satellite and 5G communications.

We've reached the Electromagnetic Inflection.

software-defined hardware == electromagnetically-governed device

Their behavior more attributable to Maxwell's equations than Newton's. A car's most expensive subsystem is its electronics. A datacenter's binding constraint is power delivery and SerDes interconnects. The F-35's avionics cost more than its engine.

Electromagnetic design is a physics problem, and at @ArenaPhysica, we're building the stack to solve it.

-> Atlas: an agentic platform deployed as the intelligence system of record for hardware workflows at companies building frontier devices, making probabilistic reasoning engines capable of deterministic engineering work.
-> The EM Foundation Model: the first physics foundation model for electromagnetism, learning the relationship between geometry and fields directly to drive the time and cost of verification toward zero.
-> The Electromagnetic IP Factory: vertical co-development of the most advanced electromagnetic IP in defense, automotive, compute, and communications alongside our most ambitious partners.

I’m proud to be building this alongside @PratapRanade , @_clairepan , @m__frei , @hk2532_harish , and the rest of our artist colony here at @arenaphysica.

And a big thank you to @packyM for telling our story and how electromagnetism (secretly) runs the world.

Hot take: healthy coding patterns matter more than test coverage! 🔥
At early stage start-ups, the reality is you need to ship fast and find PMF.
This can result in buggy spaghetti code.
The fix isn't necessarily more tests - it's better architecture.

Which AI co-pilot do you prefer for coding?

I've heard some people talk about toxic positivity and I think it's good to remember that "being positive" doesn't mean you have to pretend to be happy all the time. 🙃

Celebrate your achievements 🏆
Share gratitude 🙏
Treat the failures as growth opportunities 🚀

My startup company ran out of funding and now I am seeking new opportunities. Check out my latest blog post for more insights on this experience. #ecommerce #productdevelopment #startuplessonslearned

🔨 I rebuilt my site from scratch! 🔨

I wanted to challenge myself to create my own blog from the ground up using minimal coding libraries. Admittedly, I’m having more fun building my blog than writing articles for my blog.

@KalebMcKelvey @JoshWComeau I like split keyboards, the ability to remap keys, ortholinear keys (grid formation instead of standard offset keys), and more thumb keys.

I’ve remapped the cmd, ctrl, enter, and backspace to my thumbs which makes those actions more comfortable than using my pinkies.

What is something you wish you knew before starting your last project?

[B-Hash @brian_hayashi]

@balazsorban44 @nextauthjs It would’ve been helpful to know which tables are necessary and which are just example tables in the Prisma adapter setup docs.

[B-Hash @brian_hayashi]

It’s nice that @nextauthjs has a #Prisma adapter, but the docs are so opaque it took me forever debug the errors I was getting. Really would’ve helped to know what was going on under the hood.

[B-Hash @brian_hayashi]

@balazsorban44 @nextauthjs I got a generic prisma adapter error and a link to the NextAuth error docs which didn’t explain the error. The adapter docs don’t really explain what’s going on under the hood.

The problem was that I was using a VerificationRequest table instead of VerificationToken table.

@Annex_Canada @AbroadInJapan I’ve seen similar things in Hawaii. Tourists get charged more, but if you can show a Hawaiian ID then you get a discount.

@heyimsunflower Not really, I was working on an authorization flow and was trying to customize the email used for 2FA.

SendGrid exists for a reason 🙃
