a common mouse sensor #hardware does 3000 fps, 12 inches per second, 400 counts per inch (64μm resolution). Register 0x48 is “Pixel Data: Actual picture of surface”. 324 pixels, but you can only read 1 pixel per frame!
i.materialise is a British #3D printing company that offers, among other things, direct metal laser sintering of #titanium, with 250μm feature size.
MAX35101 is #hardware for time-domain sensing for ultrasonic heat and flow meters. Measures differential time-of-flight with precision down to 20ps, but with a minimum of 8μs. Potentially super useful for spirometers.

“In an analysis of two large-scale, nationally representative United Kingdom data sets (N = 15,874), we found that lower general #intelligence (g) in childhood predicts greater #racism in adulthood, and this effect was largely mediated via conservative ideology.”
“#Weaponry and morale determine outcomes. The 2nd largest city of Iraq (Mosul) fell when 1k ISIS fighters attacked “60k” Iraqi army. 40k soldiers were artifacts of embezzlement, and of 20k real only 1.5k fought - these mostly the AK47 armed local police. An AK47 loses to a 12.7mm machine gun and armored suicide vehicle bombs. Finally, the attack was personal - soldiers received calls mid-fight threatening relatives by name and address. One army captain did not leave quickly enough and had two teenage sons executed.” #violence #Iraq #daesh
