A thermal camera, also known as an infrared camera, detects heat (infrared radiation) instead of visible light. This allows it to create images based on temperature differences in a scene, even in total darkness or through smoke, fog, and certain obstacles

Visualization of the continuity equation. Showing how any change in mass density inside a fixed control volume is exactly balanced by the net mass flux through its boundary. Blue particle concentration represents, the green arrow represents velocity, and the orange arrows show mass entering and leaving. The density is redistributed, but no mass is created or destroyed.

As someone who builds with LLMs and diffusion models, this 14-minute heat equation video is the closest thing to a "why noise reversal actually works" explainer I've ever seen released for free. Everyone thinks diffusion is a novel AI concept. It's the heat equation from 1822. The forward process spreads noise like heat, and the reverse process is what your model learns. Bookmark & watch this weekend. Same math, from 19th-century physics to 2025 image generation.

Turn up the heat ☀️ New cities, match minutes and plenty of Lucozade 💧 See how the squad trains, plays and stays hydrated when the temperature rises.

An exercise about ants and first passage processes, solved through the bounded diffusion equation (Exercise 3, Unit 12, B3, MS327, OU). Within my brain, the concept of ants is associated to Hofstadter’s masterpiece: the GEB, specially, to both the Prelude and … Ant Fugue.

How Starship Gets Its Heat Shield 🛡️🚀 | Thousands of Tiles, One Mission The answer is a thermal protection system made of thousands of black hexagonal heat-shield tiles. Each tile is inspected, precisely aligned, and installed on Starship’s windward side to help reduce the intense heat generated during reentry.

How does the booster slam back through the atmosphere at Mach numbers that would vaporize normal aircraft, relying entirely on bare steel instead of heavy heat shields? The vehicle survives extreme hypersonic reentry by leveraging the high-temperature material properties of its 301 stainless steel skin, which maintains structural integrity well past the limits of traditional aerospace aluminum. Because it executes a retro-propulsive deceleration burn during atmospheric entry, peak thermal loads are actively managed and shed over a broader descent profile. Rather than utilizing brittle ceramic tiles across its entire body, the bare metal acts as a massive radiative heat sink—re-radiating thermal energy back into the atmosphere while structural ribs and stringers handle the intense aerodynamic stress #spacex #starship #superheavy #booster #rocketscience
