The awake city: six verbs of machine intelligence, and the one it can't compute
From WeatherNext's cyclone forecasts to Sentinel-2 CNNs and OSMnx walksheds — the six verbs a city learns, and the one containment it can't compute.
PACE, Precession, and the Sun Angle Already Written Into Your Facade
NASA's PACE and SPHEREx read Earth as a spectrum, not a picture. The projection and precession math behind them is the same math that fixes your facade's sun angle.
Earth Intelligence Is a Projection Choice: What Copernicus's 24-Hour Delay Means for Your Site Datum
The EU's 24-hour delay on Copernicus Sentinel data exposes a datum problem — why every site workflow needs an explicit CRS, epoch and projection before you measure.
23.4 Degrees and a Lumpy Geoid: the Physics Under Every Site Plan
Earth's 23.4° tilt, its lumpy geoid and your latitude decide every overhang and PV tilt. A four-line Python check for solstice sun altitude, Zurich-anchored.
PSI's 80°C Battery Trick: Solid-State Storage Learns to Last 1,500 Cycles
PSI's mild-sintering plus 65nm LiF coating keeps a lithium-metal solid-state cell at 75% after 1,500 cycles — and what it means for building-scale storage.
Switzerland's 30% solar cell — and the number that isn't on the roof yet
EPFL and CSEM certify 30.02% in a perovskite-silicon triple-junction solar cell — the physics behind the record and what it means for BIPV façade specs.
Haute-Sorne's Quiet Number: M0.3, and Why a Swiss EGS Well Didn't Shake Anyone
Switzerland's Haute-Sorne enhanced-geothermal well cleared stimulation at a felt-maximum of M0.3 — 60x under Basel 2006. What the numbers mean for your desk.
The wall that breathes: ETH's living panel banks 26 mg of CO₂ per gram
ETH Zurich's Tibbitt group prints a cyanobacteria hydrogel that banks ~26 mg CO₂/g over 400 days — part as durable carbonate. What it means for façades.
Frost climbs the mountain: Spain's shifting freeze-thaw line and the stone you build with
A new Cryosphere study shows Spain's frost weathering is climbing uphill — why alpine rockfall and stone-durability maps are quietly expiring, and the Monday fix.
TON 618: the black hole that shrank 38% without moving — a lesson for engineers
TON 618's mass fell 38% in 2019 with no new data — just a different emission line. A physicist's lesson for anyone trusting a structural digital twin's numbers.
