The Color of the Future: A history of blue

news.ycombinator.com Étienne Fortier-Dubois 2025-11-27 21:27:53

La Gare Saint-Lazare, arrivée d'un train , by Claude Monet (1877) My favorite color has changed throughout my life, cycling through the entire spectrum of visible light and beyond. I don’t remember when blue was the chosen one, exactly; maybe when I was 13 or so. After that, yellow, purple, orange, green, and pink occupied the top spot for various periods. Blue never made a comeback. I saw it as a banal, common color. After all, the sky is made of it, and the sky is everywhere. Then I realized

Anker’s Mammoth Projector Is Now So Big You Should Just Call It R2-D2

I was already impressed enough with Anker’s SoundCore Nebula X1 projector when I saw it back in April. We all dream of having our own full theater in our homes, or at least something transportable enough that we could hang a bedsheet in our backyard and pretend we’re at the cinema. It was one of the first projectors with its own internal liquid cooling system to keep it from overheating.

This Unlikely Chemical Could Be a Powerful Weapon Against Climate Change

gizmodo.com Ellyn Lapointe 2025-11-27 21:00:20

Year after year, humans pump more carbon dioxide (CO2) into the atmosphere than nature can remove, fueling global warming. As the need to mitigate climate change becomes increasingly urgent, scientists are developing ways to actively remove CO2 from the atmosphere in addition to cutting emissions. One of the biggest hurdles to scaling current carbon capture technologies is the vast amount of energy they consume, but what if there was an alternative that uses an abundant, cheap power source?

Samsung’s Galaxy Tab S11 Tablets Come in Two Sizes: Big and Absolutely Huge

And if you’re Samsung, you announce the new Galaxy Tab S11 and S11 Ultra and make everybody play a game of “spot the difference” between the two Android tablets.

Samsung’s Galaxy S25 FE ‘Fan Edition’ Is a Cut-Down S25+ For $350 Less

You already know what to expect when you see the letter FE following a Samsung product name. Short for “Fan Edition,” FE devices are a Frankenstein of components packaged together and sold for less. In the case of the Galaxy S25 FE announced at IFA 2025, the $650 Android phone has the same size 6.7-inch display as the $1,000 Galaxy S25+, while costing less than the $800 Galaxy S25.
