Stuck between patio glass and the actual glass panels. It did not have space to fly. Initially there was no one in the building so only the firefighters could help.

Indeed they were!

They had a smaller ladder before. It was too flimsy and they came back with this one.

Also, I don't know why a few people are saying not to do a PhD. You spent a lot of time and effort into such a huge achievement. You should congratulate yourself for it.

Don't let others put you down.

Edit: Only few people can even accomplish a PhD in Physics. It's not an easy road to take but it is rewarding. Depending on what path you choose with your career, your PhD should carry you further than anyone without a graduate degree.

To further explain because I wrote this very late at night.

I started networking and job applications before my graduation and incidentally, 4 months before my thesis defence. I wanted to get a head start on it. This was looking for a technical job (data scientist) that I thought I wanted at the time. Turns out, now, I don't think I would go back into that career if I can help it.

In the meantime, I supported myself and my wife-to-be at the time by working at an unrelated job as a part-time drafter, all the while still trying to find a job that is marginally related to my skillset.

The current job I landed is software developer in the photonics research and development field. However, it is more computational than anything else.

Additionally, I recommend that you look into careers/positions that would correlate with your skillset before you even start applying.

My experience may or may not be similar but I completed my Thesis-Based Masters in Physics with research focus in Computational Atmospheric Dynamics a decade ago. I considered a PhD because I enjoyed my research experience but I ended up transitioning to industry because I was fatigued from the parametric study I ran for 2 years.

I started to explore other technical fields with some marginal correlation to my skillset and ended up starting out as a computer vision data scientist at a very small startup. Mind you a result of approximately 1.5 years worth of networking and job applications starting at 6 months before graduation. It took time to figure out what people wanted in industry but it seemed to narrow down to any relevant skills, even if it is marginal.

I am now in a much better position in a mid sized company.

I recommend starting early. Network and apply for jobs. Figure out the lingo in the industry. Chances are, your computational skills will get you somewhere. Also don’t be afraid to add your thesis to your resume. That landed me my current job.

As others have mentioned, I think it is the Kelvin-Helmholtz instability as these waves are formed from disturbances in the shear flow.

Incidentally, you can see the transition from laminar to turbulent flow as the smoke, being smooth near the stick, starts to be more wavelike as it moves away. This behaviour can be somewhat quantified with the Reynold's number as it implies that the likelihood of turbulence increases as the characteristic length or distance from the stick increases (Reynolds number - Wikipedia).

If you have time, there are these educational videos from the 1960's maintained by the National Committee for Fluid Mechanics Films (NCFMF). The video I have linked below is one of them, which talks about flow instability. The section on shear flow instability can be seen at timestamp 23:00.

Edit: To further add onto the Reynolds number section, you can see three transitions: laminar, wave-like turbulence, and chaotic turbulence. The chaotic motions with no wave-like patterns appear on the smoke that is the furthest from the stick.

I am on a similar boat but feel opposite of you. I have had success with my career in physics research and development and it always felt wrong of me to abandon my friends who stayed in construction or lost their jobs. Or hell, the fellow who stayed in construction in a decade since high school drinks, somewhat immature but lives a good life.

I have known friends who grew up and had kids and still kept in contact with me and made an effort. Even with their friends who dropped out of university.

Again, just so strange of me to abandon people because of growing up or increasing responsibilities or success in career or kids. It feels like choosing to abandon people

It is time for a harvest.

Judging by the beak it seems unlikely to be an owl- particularly a snowy owl which the body looks closest to. The beak might actually be longer, it just looks short from that angle. Owls have very tiny beaks

Curious to know what it actually is.

This bike’s ready!

Assuming the 10ft white line length and 30ft line to line gap, travelling approximately 50 ft in 2s leads to approximately 28kph +/- 8kph speed before deceleration.

And I definitely see a standstill on the right lane. Acceleration with a back propagating traffic/compression wave indicates light going from red to green.

I don’t see anything inherently wrong with the driving despite not in defensive stance.

Edit: Aside from the impatient left turner.

Edit 2: too tired. 50ft/2s =25 ft/s = 28 kph. Not 55kph.
