@CarlHarrisonPhD @astormic A piezo actuator may have a travel range of 50-200nm, but precision can be down to single nanometer with capacitive feedback. Even in open loop they should be below 10nm.

@NutritionNerd Yeah, biomedical research in the US is toast if this stays that way😞.

@AndrewHires That would never happen in my neck of the wood. Some people hesitant to merge, some trying to bull-doze their way to the very front, etc...

@interesting_aIl That is one way to quit smoking😳!

@OpticaWorldwide @UofGlasgow @NASAJPL @MIT That is an interesting paper. When seeing the headline, I thought it involved quantum optics with a single (or entangled pair) photon. But they used a detector with single photon sensitivity/counting ability.

@AdrianoAguzzi Yes, we may get a real world adaptation of the movie.

@AndrewHires Yeah, more destructive than a direct ICBM hit. Pretty catastrophic for the region it would hit, and probably decades of chaos (environment, economy, politics...) to follow.

@memecrashes I Cant(or) stand those trolley problems.😅

@AdrianoAguzzi @baym Progress, nevertheless! (I once interviewed one of your former postdocs and he gave me a in depth explanation of the complexities in that field).

@Anthony_Bonato And you show it as a Pi -chart!

@ohchopper @paulg @CcibChris Nice!

@CcibChris IIRC, the featherweight version of the B36 could fly up to two days (45-50h) nonstop with a low payload.

Recursive bento boxes.

@AviationMarlene Six engines, half of the Dornier Do-X flying boat. Rapid progress in engine technology (initially the Latécoère 521 was supposed to be powered by four engines)

@kD3AN Yikes!
