[OC] Physics equations and a neural network both lose a real double pendulum in under a second

[OC] Physics equations and a neural network both lose a real double pendulum in under a second

Source: IBM's Double Pendulum Chaotic Dataset, 21 runs and 378,099 marker positions tracked from high speed film, used under CDLA-Sharing 1.0. Tools: Python, NumPy, Matplotlib.

Black is the filmed tip. Red is the rigid body equations fitted to sixteen runs, blue is a small neural network trained on 287,768 frames of the same runs. Both start from the same measured state at time zero. The dotted lines mark where each drifts more than a tenth of an arm length from the real object, at 0.91 s and 0.50 s.

Non-Physical Intelligence Has A Ceiling [D]

Reasoning alone cannot predict the chaotic physical world. Without a sensory and motor interface to reality, non-physical AI will not deliver the scientific and technological breakthroughs we expect.

Early Results Of Verastem's VS-7375 In Pancreatic Cancer, Or How To Read A Reduction In CA19-9

Verastem reported a greater than 50% reduction of CA19-9 in 13 of 14 pretreated patients with metastatic pancreatic cancer treated with 900 mg of its oral KRAS G12D inhibitor VS-7375. Whether CA19-9 reliably tracks tumor burden and can predict survival is another question.

Hobby Project: Chipgrid, a free web-based sandbox for building electronic circuits. Would love to hear your feedback!

Hi everyone,

I have been working on a hobby project: an online simulation game to build electronic circuits and I would be so happy to get some feedback on it! :-)

You can just try the app here (it's free of course): https://chipgrid.io/

I made a short demo video showing how it works. I also created a subreddit, r/Chipgrid, for everyone to share their circuits.

I am so excited to hear your thoughts! :-)

Palantir Is Building The "Brain of The Firm" Envisioned Half a Century Ago

An organization can sense and act on its own, but it has always had to borrow its reasoning from the humans it employs. Palantir's ontology hands it a living model of itself, AI supplies the capacity to reason over it, and together they might give the enterprise a functional intelligence of its own.

Innovation: America's Perpetual Frontier

At her 250th birthday, America is still opening frontiers. Boosters settle into the arms of launch towers, machines think at scale, and drugs reach targets once thought undruggable. The rational position is an almost delusional optimism about what Americans build next.

Nektar's Rezpegaldesleukin: Aiming To Restore Peripheral Immune Balance

Rezpegaldesleukin selectively expands regulatory T cells to restore peripheral immune balance. Phase 2b trials showed impressive, deepening efficacy in AD and meaningful hair regrowth in AA.

Why Licensing A Dual-Mechanism Anti-IgE Antibody Could Be A Major Opportunity For Cue Biopharma

Cue licensed CUE-221, a dual-mechanism anti-IgE antibody. A controlled Phase 2 in CSU in mainland China is expected to read out in H2 2026, after which Cue plans a global Phase 2b in food allergy.

Hemay’s Phase 2 mufemilast data suggest that oral PDE4 inhibition can drive biologic-range remission rates in moderate-to-severe ulcerative colitis. This class-level evidence may partially de-risk Palisade Bio’s PALI-2108.
