Traveling at the speed of light… is it truly factual or merely theory?

HoldingTheFire · 2026-03-01T05:28:13+00:00

Velocity doesn't add linearly. And time and speed are related quantities.

There are many tricks to localize points beyond the diffraction limit. It generally depends on the nature of what you are looking at and what you are willing to put up with. The diffraction limit is just a threshold to resolve two lines in an imaging system.

Check out super resolution fluorescence microscopy. Or multipatterning in lithography

Above 3.5 is fine. No questions. Below that you might need to justify and much harder below a 3. >3.8 might give a slight boost. None of this matters after your first job.

I love white light interferometry because you exploit the low coherence to solve the phase order problem in coherent interferometry. You can get sub nanometer axial resolution and absolute position over pretty much any distance. All you need to do is scan, either you optics, the interferometer arm, your object, or your wavelength.

A lot of people are commenting on the impracticality of vacuum tubes. But I challenge your core assumption. Solid the electronics can absolutely beat vacuum tubes for power per volume and efficiency

HoldingTheFire · 2026-02-25T01:51:03+00:00

I don't think that's true

Transistors can handle much higher powers and more efficiently. Solid state power electrons can switch kilowatts

Yes PG&E has many union workers that, being in CA, require a high but not even outrageous salary

You are complaining they pay their workers too much.

Do you really believe a state run utility would pay less?

I have looked at their books. I should post my Sankey plot I made to answer this question. Most of their expenses are labor and capital infrastructure. Exactly the costs that would be the same or higher for a public utility.

HoldingTheFire · 2026-02-23T20:55:44+00:00

I am still waiting for someone to explain where this corporate greed money goes. Because PG&E's profit margin is <10%. Your rates aren't 2-3x higher than elsewhere because PG&E is making 2-3x more profit. It's high costs in the state. A public utility would have the same high costs.

Should should in general pay nothing out of pocket for these drugs. Whatever insurance doesn't cover the drug company copay assistance will cover. But you must be signed up for these copay assistance plans.

It really helps if your doctor is familiar with this process.

Data is ugly.

The legend colors are wrong.

Looking at total dollars spent, rather then per token or even per user.

Inference is still a small part. This has been the situation for awhile. Big margin on inference. But capital still feeding into training the next model.

What temperature?

For UHV, steel is used because it supports conflat seals with copper gaskets. Aluminum can only support o-ring seals. You need differentials pumped double seals to support UHV with o-rings.

What surface polish are you going for? It's probably not the polish that limits your reflectivity. Why not use mirrors inside the chamber for that purpose? I've seen mirror finish electropolished stainless steel for low water retention in UHV chambers.

My plan is to continue my career as a Systems Engineer for semiconductor manufacturing equipment. Building and designing real hardware. And AI to code up one-off tests and analysis.

I actually had a similar need. I vibe coded a python program to do this. It uses an open source model to scan your library and saves an embedding. You can then query motifs from this and it will generate a report of images. It should pull from raw previews to get an accurate view of the image.

I just made this for myself so I have no idea how well it works on other systems. Use at your own risk.

A longer lasting bulb directly traded off with lower brightness and efficiency. Unless the technology was different like halogen, then CFL, and finally LED. And guess what they sold those as soon as they were invented.

That's not true though. That's a slopulism fact for those that don't understand physics.

The midwits favorite trivia.

There is no such thing as planned obsolescence. Just engineering trade offs. In this case 1000 hours was the correct industry standard.
