Udayan Adhye | Finance & Investing on Instagram: "Copper just quietly hit $12,000 a ton. And no, this isn’t some boring commodity story. Every Nvidia chip, every AI server, every data centre upgrade runs on copper. AI data centres use 3–4x more copper than traditional ones. EVs. Power grids. Cooling systems. All copper-heavy. Demand is exploding. Supply is cracking. Chile just hit 20-year production lows. New mines take a decade. This is what real structural shortages look like. Ignore copper at

Knowty on Instagram: "Dm for Credit / Removal The post showcases a plasma globe video where purple plasma filaments respond to hand touches on the glass surface, prompting the author's surprise at glass seemingly conducting electricity. In reality, glass insulates direct current but permits capacitive coupling with high-frequency alternating current, allowing plasma streams to follow the electric field without electrons crossing the glass. Posted on December 25, 2025, the video amassed 1.7 milli
