The mechanism in this was shockingly impressive.

For me, it was the requirement to do so many calculus problems. I could have sown I was going to be doing comically difficult math problems out of school, and I don't think I've done a single calculus problem in nearly 15 years. Don't get me wrong, I've done tons of pretty intense math (mostly fluid mechanics), but I just expected calculus to have such a bigger footprint in the engineering world.

We've got a severe problem at my company. Management doesn't want to invest the time or resources to developing a standardized training manual, training material, or even a Lessons Learned catalog, and everytime we get a new employee it's like 6 months of them slowly picking things up before they are useful and probably a year and half before they got comfortable in their role.

Did any of you have this hurdle? And how did you get management to finally listen and invest the resources to do this properly?

Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up. This keeps solar fuel production more stable while reducing cost and complexity.

Trump slams Netanyahu for truce violation, says it is still in effect and that he is not seeking regime change in Iran.

In newly signed legislation in Virginia, social media companies are required to restrict use to only one hour per day for kids younger than 16 years old.

On one hand, great, kids need less social media. We're seeing how absolutely toxic it is. On the other, this shouldn't be the states call to make.

Wanted to ask about this. I do not work in California, however many of our vendors and customers are seeking to swap to MIL-PRF-8625 Type II, when they historically used Type I.

I'm totally on board with this - anything I can do to push safer, less environmentally destructive processes is a win in my book. But I understand that not all companies are interested in jumping ship so fast.

So I wanted to ask, what's your companies take on it? Did you know about the industry phase out?

The US Space Force is tracking 20 pieces of debris from the Intelsat 33e.

I've been dealing with this for months. I've received yet another drawing from a company calling "Diameters on a common axis/center to be 0.XX" TIR U.O.I. "

Total Runout requires a Datum. Your "common axis" is not a datum and can not referenced. It's driving me mad. Like, where did everyone get this notion that it's acceptable? It'd be one thing if it was just one or two drawings, but I'm into the dozens at this point. It's getting to the point that I'm starting to question if I'm either the one in the wrong or everyone has some sort of mass psychosis.

Am I in the wrong here?
