Thanks for the link. What I'm wondering is how this guy aims to succeed where previous X-ray lithography efforts failed. For reference X-ray litho was competing with EUV. What was it that held the approach back? My guess would be that that the industry simply coalesced around EUV and X-rays were abandoned. But that just makes me wonder why the industry coalesced there. Perhaps synchrotons are not cheap / easy? But don't university labs build these all the time?
As far as I understand it real X-Rays are too hard to handle in general, and though more precise because of shorter wavelengths etch too much away from the substrates. EUV is just soft enough, to not do that(as much). That seems to be the main reason all the effort went into EUV of 'just the right wavelength and energy.'
This is the original seminal work on coffee drop evaporation out of Sid Nagel’s lab, with theoretical support from Tom Witten and Todd Dupont and their students.
Like everything out of the Nagel lab, at least from that era, it combines a keen curiosity about things we take for granted with rigorous physical experiments and insight.
The Nagel/Witten collaboration was one of the many lovely things at the University of Chicago in that era, and it was always tremendous fun to see them present and get a glimpse at how they approached problems.
It was like looking over the shoulder of giants: often humbling and always educational.
A new hearing loss modality seems to be gaining traction -- "hidden" hearing loss. A core symptom is difficulty parsing speech in noisy environments. Caused by repeated exposure to loud noises. Don't know if folks around here are going clubbing much but I'm under the impression that it's gotten way louder recently. Live music as a whole is pretty popular these days.
Apparently most who have it don't have the classic symptoms: tinnitus or hearing loss picked up at the audiologist's office.
I definitely have this. My friends can usually understand one another shouting in a moderately loud bar; I can’t understand them at all.
I don’t know if it’s technically hearing loss though; I feel like I can hear the noises my friends are making, I just can’t segregate them from the background noise enough to parse the former as speech.
I wear hearing aids for moderate hearing loss. They are optimised for picking out speech from the background sounds and in the open air or rooms that have good acoustics my comprehension can be better than people with notionally better hearing. But some sounds are very effective jammers for hearing aids, notably running water, boiling kettles and, unfortunately, the ambient noises in typical restaurants.
