Masks to protect from spreading a pathogen vs masks for hiding secret police, universal basic income vs trump handing out a $5000 per person bribe before the election, media that reported truth vs media fighting over the right to report lies. We are in strange times

I think every advance in technology lowers our quality of life. Before the phonograph was invented, most households had a place where family members would get together and play music. When the phonograph arrived, you could hear the best in the world, and how could you compete with the best?

Currently performing SEM on zinc anodes 🔬. It looks pretty, but one of the major issues with rechargeable zinc #batteries apart from hydrogen evolution is the formation of dendrites, which lead to capacity loss and ultimately short circuit the cell🪫.

Shatter cones in a recently discovered Precambrian impact site near Santa Fe, New Mexico. Shatter cones are the result of shock waves generated by the energy of a point source impact. These shockwaves radiate outwards from the point of impact, fracturing rock along the way.

A M7.4 earthquake struck the Philippine subduction zone today, causing damaging shaking across much of Mindanao. Several people have died. This is the Philippines' second deadly earthquake in two weeks. Are the events related? And how does this quake compare to the nearby M7.6 in 2023? ⚒️ 🧪

#Carpathite is composed of hydrothermally deposited coronene. Coronene is also proxy for wildfire activity, a function of terrestrial biomass, atmospheric O2, and ignition sources like lightning, volcanoes, and bolides. The oldest known occurrence on Earth dates to the early Ediacarian. #MinCup25

The huge minerals collection “terra mineralia” in Freiberg/Sachsen, Germany, is certainly one of the most respected minerals museums worldwide, a true gem and must-have-been for any lover of minerals. Besides, the small town Freiberg is a good place for a stay.
