America runs on the metric system. Secretly. 📏 Every inch is legally defined as exactly 25.4 mm. What unit confuses you most? #metrology #metricsystem #science #measurement #didyouknow

Hubble's mirror was polished almost perfectly… to the wrong shape. Off by 2.2 µm — about 1/50 of a hair — because a worn fleck on a test rod fooled the laser. Glasses for a telescope in 1993. Calibrate the tool that checks your work. #Hubble #NASA

Nature's Rulers #2: An ice bath gets you within about 0.01 °C. Not good enough? Labs use the triple point of water, where ice, water, and vapor coexist in one sealed glass cell. It's about 100x more repeatable. This TPW was created by me. 💧

Your dog knows you're almost home. 🐶 With 200–300 million scent cells to your 5 million, some dogs can smell parts per trillion, and one researcher thinks they may even "smell time" as your scent fades (still a hypothesis). Does your dog wait at the door before you get there? #metrology

Your phone falls back an hour Sunday without asking. Here's who actually tells it what time it is. ⏰ #DaylightSaving

In 1983 a jet ran out of fuel at 41,000 ft because the fuel was figured in pounds instead of kilograms. The captain glided it to Gimli, Manitoba, and everyone survived. Always check your units. ✈️ #metrology

How can a clock with no hands be more accurate than your smartwatch? ⏱️ It's a glowing cell of rubidium gas, and its atoms tick about 6.8 billion times a second, a frequency nature never changes. GPS keeps it honest over the long run. What's the most precise thing you've ever measured? #didyouknow Bob, Measured · @blizaz_2p0x1

New for 2027 in Call of Duty League: Hijack replaces Overload as the third mode, and in Major Grand Finals the losers-bracket team gets zero map bans in Hardpoint, S&D and Hijack. The winners bracket now buys real map control. Worth tracking how often it decides the series.

Nothing fights socialism like free money from the government

Be careful out there. Hehe

In the shadow of Charlie Kirk’s murder—a sniper’s shot silencing a patriot—we must reject poisoned discourse. Choose vigilance over vengeance, conviction over conspiracy. Kirk fought for reason’s republic; let his legacy demand we do the same. #TPUSA

Can’t get a better high and tight than at a base barber shop. Also, why don’t all barbers have a vacuum at the end of their clippers? #AAFES

House passes 'big beautiful' budget, but no tax breaks on tips, OT, or SS yet. Feels like Ryan's days—big promises, thin results. Johnson’s got the gavel, but will he deliver or just echo the past? 🧐 #Politics #TaxReform"

Anyone else remember this? One of my all time favorite shows.

Jerusalem artichokes: easy to grow, low maintenance, and a great preparedness crop. Hardy tubers multiply yearly, while their pretty yellow flowers brighten gardens—beauty and bounty in one!
