A new Mac laptop uses a 5 nm fabrication process.   The silicon atoms from which it is constructed have an atomic radius of 0.132 nm.  There is still some room at the bottom, but there isn't tons of it.  What's happening as chips get smaller and smaller is that quantum effects become harder to mitigate.

Quantum computers aim to take advantage of these quantum effects to achieve massive parallelization.  Some approaches to building quantum computers take advantage of the tools of nanotechnology, for example, atomic tweezers that can manipulate individual cesium atoms.  Other tools from nanotechnology, like electron beam lithography are used to fabricate superconducting quantum processors sort of like an etch-a-sketch.

Meanwhile, cryogenic electron microscopy is almost routine for the study of cells, enzymes, and pathogens.

Nanotechnology is being used to design new kinds of batteries and solar panels and to understand how to design materials to have desirable properties.

I'm not sure where nanotechnology ends and material science, chemical engineering, or synthetic biology begin.  I think they all overlap to some extent.  They all are concerned with making and understanding the interaction of inconceivably tiny structures..

Merle needs a bit of help.  I'm teaching a short online course this week for the U. of Ottawa, and one of the guys in my course is the Dean of the School of Engineering. (Why, I can't imagine.)  Anyway, his research field is nanotechnology.  Is it here?  Where has it been applied?  Is it an incredibly generative technology that will change our near-term future?  HELP, and thanks.

He said the city is going to “flood our system with mental health professionals and law enforcement working as a team to move out the disorder that's clearly in the subway system in our city.”

A couch by every turnstyle?



A new collective?  A murder of crows; a flood of psychiatrists?



Rumor has it that Biden is considering sending mental health professionals to the Ukrainian border.



Needless to say, I have volunteered.
