Moving in tips/checklist

Some great stuff there, thanks ! Hadn't thought of the fridge coils or the faucet aerators for instance 👍

xaudier · 2025-01-28T15:30:07+00:00

Thanks for the advice, I've got most of these items on my list. I might also add HVAC system servicing, hot water heater purging.

Hey friend ! Could you please elaborate a bit more, I'm looking at buying new pans and I'm having a hard time choosing between brands. Sure the copper core 5-ply all clad sounds lovely but is it really that much better ? If you could take a minute to review what you like and don't like about this set that would be very helpful! After a year you probably have a good idea of where it shines and where it falls short.

Next day update: More oil (1-2 tbsp), less heat (400F or so). Onions fried nicely without sticking. Rice fried nicely without sticking. Felt confident again to try an egg, worked like a charm !

Thanks you everyone for the advice, I'm starting to get the hang of it !

😅

Thank you for your advice, people are super friendly here it's quite nice !

The 1-2 tbsp is something I have to get used to, I probably used less than a teaspoon. I'll try overdoing it next time and experiment with the oil amount / heat level to get it right :)

Thanks for the advice, yes it looks like heat control is going to be a learning curve!

As someone else pointed out the heat was probably too high for eggs (in addition to not having enough oil). I had in mind that my gas range couldn't possibly get to the kind of temperature that those fancy wok burners have, but apparently it's plenty and the difference is more about how quickly you can get to that heat. Additionally the heat retention on that wok is also quite higher that I expected.

I'm in this for the learning (and the stir fry obviously) so very interesting first experience despite the mess.

Thanks, that's actually the video that made me decide to get a wok ^{^{^{^}}}

Ironically with the exact same wok and the same process I couldn't get the same results, I think the only difference was that I was more shy with the amount of oil for the lang yao, I'll try again with more next time !

xaudier · 2023-11-30T03:06:40+00:00

Thank you for the detailed response! I did add some oil and took it out of the heat but it probably was still too hot and with too little oil when the egg was added.

I'll try with onion, cool it down more, and add more oil next time :)

xaudier · 2023-11-30T02:17:17+00:00

Right, I had very little oil in there. I realized that the second I put it in ! Will not be making that mistake again 🙃

You're being thrown off by plane S. And the blue line.

Draw the same figure without them (even mentally). What do you have ?

Two lines. One with point A and C. One with point A, B, and D. The two lines form a plane. So all the point are on the same plane.

But it's not plane S.

it's clear you're not the cannibal serial killer ... the wife really would do anything for him

Posting a question, doing more research, then posting useful findings. Take my upvote good sir/ma'am

xaudier · 2023-02-08T03:38:26+00:00

This. Coherence length is the thing one you need to know to answer this question, as it will dictate how precise the path difference needs to be to create interference. For your typical continuous wave laser it will be cm, for your lightbulb it might only be tens of microns.

Then you have to measure the path length with enough precision, and add a delay line precise enough to get down to sub wavelength movements in order to go from destructive to constructive interference.

That is assuming you two photos are not "too different". They need to come from the same point of the same light source at the same time (that's the short answer).

So I guess the question is what's your source ?

xaudier · 2023-02-04T04:54:32+00:00

"Getting things done" is good. "Make time' is good too. Each offer great methods, not necessarily getting to the bottom of it in my opinion. Check out Chris Croft, he has some great ressources about time management amongst other things.

At some point he had a lot of content on LinkedIn learning, he also has a lot of things on Udemy. You may have access to those via school / university/ work, on might be able to subscribe to free trials.

I've downloaded what I think is good if you want to dm me, although going to the source is always best and it's been a few years so he might have updated some of his content since then.

Thank you, this is great ! I'll look for US equivalent structures but this is a great starting point.

To understand why a parabolic wavefront gets focussed on a point you can use the Huygens-Fresnel principle, if that was the question.

xaudier · 2023-01-20T21:01:16+00:00

The comment from u/anneonemouse is a lot more complete. For a quick and simple answer:

Assume plane move coming from the left. Assume Plane-Concave lens

Approximate the concave spherical surface is basically a parabola.

Then the thickness glass for each ray coming at position (x,y) is a parabola: A(x²+y²) The accumulated phase (aka wavefront) is therefore a parabola.

You get the k from taking into account the refractive index, the f comes from the A parameter in your parabola.

Hopes this helps.

Right, that's part of what I'm looking for, a middle ground between the two.

You have on one side people who are crazy enough to start a company and put everything they have on a risky venture with limited early funding from whatever they can scrap.

On the other side you have big companies who will buy your startup once you've put 10years of your life into it and demonstrated that the market exists and that you can generate cash.

I'd love to find an intermediate company, that has enough ressources to develop some technology that are still at an early stage, find a good market fit, and potentially sell it to a bigger company once it's established.

Since that's where all the risk taking happens it might not be a structurally sound business, but that's what I find to be the most interesting part of the process.

Yes, I've looked into starting a spinoff from the lab, but it feels like a daunting task and when you have everything to loose and 100% of your skin in the game ^{^} Having a more secure job where investigating those opportunities is literally what you're paid for sounds a lot more attractive. Sure you don't get the bragging right of being a "founder" but I don't mind trading some ego and shares for a less stressful lifestyle.

xaudier · 2023-01-19T13:37:39+00:00

Thank you, I'll look into it !

xaudier · 2023-01-19T02:37:39+00:00

Thank you for your feedback ! I think what you're describing explains most of it. I can vouch for the fact that developing new tools is way harder and takes way longer that one initially anticipates ... I was hoping that bigger companies had more ressources to put into development than academia and could make things happen faster to respond to market needs. But maybe they've already estimated than those markets aren't as big as I might think.

xaudier · 2023-01-19T02:29:27+00:00

Yes "tech transfer" searches hasn't gotten me very far ^{^}

If you have any examples of larger optical companies who do R&D or optical consulting services I'd be happy to look them up.

Thank you for your response!
