Landau Distribution Is Wrong for Thin Silicon Detectors
The Landau distribution is wrong for thin silicon detectors. Here's why Bichsel's straggling function replaced it, and when it still burns you.
Photon Guy
Photon Guy writes at the intersection of particle physics and heavy computing infrastructure. He spent years at CERN working on silicon particle detectors — the sensors that catch what the world's largest accelerators smash together — before moving into the data center industry, where he works on the machines that power the internet and AI. ScienceShot is where those two worlds meet: real physics, real engineering, strong opinions, and no press-release rewrites.
Wafer-Scale Inference Ends the GPU Cluster Era
Everyone's cheering GPT-5.6 Sol's 750 tokens per second. They're missing it: wafer-scale inference means OpenAI is quietly retiring the GPU cluster for its frontier model, and rewriting the physics of the AI data center.
Co-Packaged Optics Is Killing the Pluggable Transceiver
Everyone is cheering co-packaged optics for saving power. They are missing the real story: the pluggable transceiver, the most-swapped part in any AI data center, is being quietly executed.
AI Data Center Water Didn’t Vanish, It Moved
Nvidia and Microsoft say they've crushed AI data center water use. They're right, inside the walls. But the water did not disappear; it evaporated at the power plant instead, invisibly and at scale.
Webb Telescope Reveals Interstellar Comet 3I/ATLAS Predates Our Sun
Webb's latest data on interstellar comet 3I/ATLAS reveals a 12-billion-year-old cosmic visitor carrying deuterium 30 times higher than any solar system comet — and chemistry unlike anything we have ever known.
The $1 Trillion Data Center Boom Is Breaking the Grid
The AI data center boom has officially gone parabolic: global spending is crossing the $1 trillion mark in 2026, power demand is set to double, and the grid can't cope.
How Liquid Cooling Is Solving AI’s Heat Problem
AI racks now generate 100 kW of heat per cabinet. Liquid cooling has gone from a curiosity to a survival strategy — here's why the entire industry is making the switch.
Microsoft’s Lead Swap Makes Qubits 1,000x More Stable
Microsoft's Majorana 2 chip swaps aluminum for lead, boosting topological qubit parity lifetimes by 1,000-fold to 20 seconds. One material change that could redefine the road to fault-tolerant quantum computing.
CRISPR Makes History: One Injection Ends Hereditary Angioedema
In vivo CRISPR gene editing has achieved its first Phase 3 victory: a single injection of lonvo-z cut hereditary angioedema attacks by 87%, with 62% of patients remaining entirely attack-free.
JUNO’s First Data Shatters Neutrino Precision Records
China's new JUNO neutrino detector has achieved 1.6 times better precision than all previous experiments combined—using just 59 days of data—bringing the neutrino mass hierarchy closer to resolution.
Is 6G a Thing? What Is Real and What Is Hype
Is 6G a thing? Yes — standards work has officially started, but not the way the hype says. What is real in 2026, and what arrives by 2030.
