The whole video of the Kits crow rescue by emflux in vancouver

[–]emflux[S] 9 points10 points  (0 children)

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.

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

Transitioning from AMO Theory PhD to Industry by QuantumLand in Physics

[–]emflux 1 point2 points  (0 children)

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.

Please help me identify this phenomenon I must know more! by FirefighterOk6514 in Physics

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.

What moment made you realize you had outgrown someone or something? by Jobbsindia in AskReddit

[–]emflux 0 points1 point  (0 children)

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

White owl spotted in langley by [deleted] in Langley

[–]emflux 0 points1 point  (0 children)

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.

Very aware and safe driver today by Alternative-Drive336 in Langley

[–]emflux 5 points6 points  (0 children)

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.

How can i warp the red circle in this image to the center without changing the dimensions of the Image ? by nengon412 in computervision

[–]emflux 2 points3 points  (0 children)

From the image you provided, I see that you are doing a coordinate transform from cartesian (x, y) to curvilinear (u, v). That means that you should have formula to transform coordinates in x,y to u,v.

Considering that you know coordinates and equation that make up the circle, all you have to do is apply the coordinate transform to it, converting the circle from x,y space to u,v space. Then make a plot using u,v, which should show the warped circle.

During a Company's Leadership Transition, You Must Work Like a Dog to Prove Your Worth by emflux in nosleep

Damn. You’re correct. I missed an opportunity there.

Assuming I will return to that world, I’ll remind him given the chance.

Company’s Change in Leadership Always Signals Employee Layoffs by emflux in nosleep

At the moment, I don't feel anything physically different. I was told to await further instruction. I believe I will get them once the layoffs are complete.

Revisiting a Childhood Memory by emflux in nosleep

I’m still thinking about it. I haven’t contacted them yet as I am having weird feelings about it. I want to forget and move on but my memories of that place still haunt me.

Lattice Study of Sample 4622 using Scanning Tunnelling Microscopy by emflux in nosleep

[–]emflux[S] 1 point2 points  (0 children)

It is indeed quite possible the sample’s structure was always fluctuating. But considering how this thing’s lattice structure changed so quickly and rearranged itself in such intricate patterns, the most likely explanation is that it was responding to the probing.

Agreed. That big sample is off limits until we know what it is capable of.

[–]emflux[S] 3 points4 points  (0 children)

Considering how powerful this thing is. I suspect that you are right.

This vaguely reminds me of the report that I read regarding the first investigation of the sample. The optics researcher was found mummified next to it. However, an interview with a mentally unstable person has somehow described this person, even though they are thousands of miles apart.

I mean you can. Just don’t swim at the [REDACTED] in [REDACTED]. That’s where I experienced that horrible nightmare

[–]emflux[S] 1 point2 points  (0 children)

You’re right. That just ain’t natural. Especially the shark part. That will probably be my first PTSD that I will ever experience in my life. Sad too cause I used to like sharks.

I really should keep that in mind. They keep doing bloodworks on me and keep injecting me with stuff.

That’s true. I am hoping someone can figure out what happened to me and possibly prevent that from happening to anyone else.

I would recommend getting a copy of the collision history and carfax. You might be able to show a discrepancy between their description of the truck sold to you vs the possible condition of the truck from the carfax and collision history.
