In his current situation, if he zones out, he produces nothing. In the situation where he's aided by the potentially faulty described system, if he zones out, he produces erroneously transcribed data.

What? In his current situation, if he zones out, he can produce erroneously transcribed data too. What's your point?

BS in Applied Physics. I work at a national lab (9 years now, since I was 25) on astrophysics projects in a Physics division, but mostly I work on software for data management, workflow management, data access, databases (multi-petabyte distributed and otherwise), and sys admin stuff. Lots of python and java, lots of kubernetes as of late. I occasionally drop down to working on things related to data pipelines, mostl…

Where should people who are good at software development but don’t have physics degrees look for jobs where they can use their expertise to help science/academia rather than dating apps for dogs?

I have a masters in HEP and have experience working on the CMS experiment at CERN for a year as part of my Masters.

I left physics for data privacy in 2017 (PhD programme).

The main reason was that I didn't really feel like I was tackling real issues (real and immediate to society) if I continued work in physics.

The swap has been difficult and I am at a disadvantage wrt to colleagues that come from more relevant backgrounds (e.g. Computer science or Applied maths) but at the end of the day I feel a lot better about the contribution of the work (to society) and also about job security in the future.

I am a physicist working as a physicist! My field of experimental particle physics, at least, is very hacker-ey: we develop instrumentation hardware, low-level data acquisition software, database and web apps for experiment operations and monitoring, and the like, beyond the data analysis. Of course, there are many industry opportunities for people with this kind of experience. In addition to the issues pointed out i…

Sounds like engineering and SE, not physics

Physics PhD, 2015. I knew from the start of my PhD that I didn't want to pursue academia. The PhD was like being in a band for 6 years and doing really cool stuff. Went right into industry after PhD working for a life sciences company in systems engineering (the product design type, not the computer networking type). Now managing a small team designing robotic systems to automate chemistry/biology research.

I'm in a similar path, but struggling with it. Any advice on who/where to apply to? I'm really into med/biotech and just love it.

:) That's a good one, Devaney was more my era!

Devaney was my advisor's advisor when he did he his PhD at BU. I took a course on discrete dynamics and chaos and wrote my senior year thesis on bifurcation diagrams. We used this textbook by Devaney: https://www.amazon.com/First-Course-Chaotic-Dynamical-System... Was absolutely fascinated by the class. One of my favorites from undergrad.

I had his Chaotic Dynamical Systems book checked out from the library for years and carried it everywhere. I should find a copy, what a great book!

I wonder if there's a good sort of "postmortem" on what happened to NLD and Chaos. It seems like everyone said, "Ok, that's a thing and it explains a lot but we can't do anything with it."

I’m working on reducing the quantum noise of gravitational wave detectors as well as work in quantum metrology. Measurements on the quantum scale using light are still relatively unexplored and there is a lot of work to do. I just sent my first paper for publish, a new design for a gravitational wave detector with reduced quantum noise

wow. interesting.so we might be able to detect gravity waves without kilometer long lasers?

I'm not a physicist, but a physics drop-out. However, I am still in touch with many of the people I studied with. Only a few stayed in physics in the end. One thing I noticed is that because physics has multiple decades more experience with dealing with big data compared to just about every other scientific field, a lot of physicists who jump ship tend to end up in a position where they can apply that expertise. I wo…

there is a long and distinguished history of physicists in biology (w some nobel winners). but ultimately, i wonder if a physicist could do xray crystallogrphy on the microbial fossils found on mars to determine their genetic basis. (dna fossils?)

Here's another story that ain't so glamorous:

BS Physics 2008. Somehow landed a 'dream' job with a major DoD contractor, despite the recession (total miracle). They closed up our plant, due to the recession, in 2010 and I moved to a smaller contractor. Got through the whole clearance process only to find that my (now) spouse was a lot better choice than the rest of my team. Good work, but the heart wants what it wants. Jumped with no safety net, and got into neuroscience where my spouse got into grad school. Worked there for free for a few years and got into grad school. Boy, was that a mistake! Horrible grad experience in neuroscience and quit with an MS. Was unemployed for about a year with a nasty depression and health issues in the family. Finally working in DBA stuff and data science. Still love bio/medtech and neurosci, but there just aren't the jobs here (need to stay local due to family health issues).

Overall, not that bad considering the recession, doing about average against my other graduates of 2008. Still, the corporate DBA stuff is ungodly boring and the family health issues aren't a snack.

In the end, we all try really hard, but kids, health is everything. Everything else falls to the floor in the face of health issues.

Sounds fascinating. What coordinate systems are used for treatment planning? Given how much bodies can change over time, and the difficulty of re-achieving a specific pose, I'm curious if there are interesting ways to correlate measurements over time. Certainly, medical training involves learning lots of prepositional anatomy words like "antecubital" but is there anything more precise, a GPS system for bodies? This s…

It's much more primitive than you think. Dose distributions are simulated based on a CT/MRI that was acquired before treatment (treatment often lasts weeks). Only minor corrections are made when anatomy changes during the course of treatment, even though the patient is often losing tons of weight due to chemo, etc. There are quite a few tools that help with patient positioning, like vac-lok bags or literally molding…

Makes sense; thanks. I'm out of my depth but it seems neurosurgery may just have it easier here, being able to fix a rigid stereotaxy head frame and fiducial markers across both imaging and therapy. Not to mention less tissue deformation enabling a gamma knife intersection-of-beams approach (i.e. ~200 collimated, mm-wide gamma sources).

Not to be glib but on behalf of the thousands of people going into a radiotherapy clinic today for treatment, thanks for working to improve these techniques.
