How does an LED light change when dipped in liquid nitrogen? 💡 Museum Educator Adelaide plunges an LED into liquid nitrogen and watches its color shift from orange to yellow to green. Temperature affects the LED’s “band gap,” the amount of energy electrons need to jump across the material and create light. As the LED cools, the energy gap increases, and the light shifts to higher-energy colors. When it warms back up, it turns to orange again. #Chemistry #ScienceExperiment #Light #LiquidNitrogen

Do you know the truth? I discovered that LED bulbs, with their high blue-light output, are really messing with our health! It can affect our sleep, strain our eyes, and even add to unnecessary stress. My husband—who’s extra sensitive to light because of Lyme—felt it first-hand. (He used to wear sunglasses inside our house!) Our first swap was the bulb in his office. We swapped the LED for an incandescent, and the difference was night and day. Turns out that incandescent bulbs are the safest way

(Et s'en sortir.. étant SDF) 😸🌳 Cagnotte en bio. 😄 Sinon rien t'empêche de ramasser des mégots et sensibiliser à ton tour, ça aide aussi ;)"

#WATCH | Kolkata | TMC MP Mahua Moitra says, "Bengalis are a very proud race. We led the war for independence against the British. Who were the Gujaratis?... 68% of the names of the people who were killed and incarcerated in Kala Pani were Bengalis, followed by Punjabis. Can you name me one Gujarati who was there, apart from your big hero, Veer Savarkar, who only wanted to sit and write apology letters? Please let us know..."
