Physics teachers. The light ray puzzle below is absolutely fantastic. Have a go yourself! The Ss will love it 🙂 (Hint: Go West from the Star to start) Pls RT! 🙂 Will post solution in a bit!

Use the Kalman Filter, even if you don't know the theory! Join me for a free mini-lecture series ▶️ youtube.com/watch?v=HCd-le… Our approach is simple and intuitive, starting with recursive filters like the moving average and low-pass filter, with code and numerical examples.

I made a tool to calculate annual 📅 direct sunlight at any location on Earth. Unlike traditional sun charts, this one accounts for shadows cast by buildings and terrain. It also doubles as a Rorschach Inkblot generator 😅 Link in replies. #solar #solarpower #renewables

Time-series prediction with XGBoost💡 → You CAN use XGBoost for time-series prediction. → However, you first need to slice your time-series data into (features, target) pairs. → Set a window length (aka feature vector size) and step size (to control granularity) and iterate

Landed in Vancouver! If you are at #CVPR23, let's chat about topology🍩 & geometry🌐? At 9am at the TAGinDS workshop tomorrow (East 16), I'll present our survey of topological neural nets w/ Mathilde Papillon🦋 mathildepapillon .bsky .social Sophia Sanborn Mustafa Hajij @ICLR 2025 to show how to process relational data🖇️

I am looking for a postdoctoral associate to join my group. Prior experience in the field of nonlinear optics, metasurfaces, integrated nanophotonics, and nanofabrication is a plus. If interested, please reach out to me at: [email protected]

Simulation nodes are official in Blender 3.6! This opens opportunities for running physics sims with geometry nodes 💪 Here's me messing with a basic 2D Ising model with a metropolis algorithm. Tbh it isn't fully working but you see what I mean... 😅 #b3d #ScienceTwitter

You can use Blender's geometry nodes to solve physics and electromagnetic equations such as Biot-Savart law. You can calculate the magnetic field of a coil anywhere in 3D space and visualise the magnetic fields. Additionally, you can see in real-time how the magnetic field lines

In 1975, the Japanese physicist Yoshiki Kuramoto introduced a mathematical model that describes how synchronization occurs in collective systems. The Kuramoto model has proved useful for modeling synchronization in networks from brains to power grids. quantamagazine.org/new-proof-show…

Writing is an absolutely critical skill… and one that can be improved dramatically. Doing so requires not just repetitions, but deliberate efforts to improve. Some tips here: docs.google.com/document/d/1jB…
