I liked working for BASF to a point but was getting burned out a bit towards the end and without that PhD had hit the glass ceiling early on. I like them a lot better now as a supplier of catalysts for MY business.My last job was with a Siemens company. They bought up a bunch of small and medium US nuclear companies and cobbled them together. The infighting for control was awful - worst company politics I've ever seen.
Interesting indeed.Can someone shed light on something? Why is that for 4 years it wasnt cool for posters on VN to say **** Trump, werent allowed to denigrate his wife and children, publically couldn't talk about blowing up the WH and murdering Trump. And yet now the RINOs have been enjoying their fit of mud slinging as soon as they get the chance.
So I had a great example of the outright stupid **** happening right now with the next generation yesterday. A protege wanted to bounce some ideas off of a design he was supporting in another group. It’s what is called a classic “head mirror” periscope optical path. This architecture has been around for well over 50 years. And the approach is always the same, a stabilized “gyro shaft” of much higher inertia gear or band coupled to a pitch mirror with a 2:1 gear ratio. The answer is always the same. You stabilize the reference inertia shaft and point the pitch axis mirror via gearing. The mirror motion response to base inputs is a disturbance into the stabilized inertia shaft. I’m not revealing secret sauce here this is literally 50+ old textbook kinematics.I can't say there's no progress, but it's certainly different. In my time I've seen the progression in music from records to tape to CD to various forms of other digital storage and back to vinyl ... from vacuum tubes through transistors to very miniaturized large scale integrated circuits - no need to even memorize resistor color bands. Analog to digital was quite a jump compared to an endless progression of phones etc that really aren't quantum jumps of technology. I'll admit electric cars - at least the power production part has some real advantages in simplicity and performance, but at the cost of dragging around a ton of batteries that have significant disadvantages such as refueling and in the end a questionable power grid to charge them. It seems like for the most part it's not big jumps in technology anymore but just version changes to keep techies happy. Now the 1TB external drive that just came today is less than a third the size of my cellphone, but that just means it's going to be harder to keep up with.
That simply couldn't be. The younger generation is always right. Didn't you get the memo?So I had a great example of the outright stupid **** happening right now with the next generation yesterday.

So the crux of the design relies on the gyro shaft inertia being several times as high as the pitch mirror inertia. There are rules of thumb for that ratio even. It’s verboten to not maintain that inertia spread or even god forbid reverse the ratio. So the design morons reversed the ratio. That’s fatal. To wit I asked the protege “where the hell are all the experienced mechs that know better and know to at least protect that ratio if they can’t optimize it?!”
“Well… they’ve all retired.”
“Damn son… I’m sorry you’re screwed. That decision was fatal for the design”

The kids were getting now aren’t stupid. Not by a long shot they are better prepared than we were for their profession. But to use a worn out phrase “they don’t know what they don’t know” that is why you have those crotchety old grey beards.That simply couldn't be. The younger generation is always right. Didn't you get the memo?
Hilarious .... 39% of Biden's voters hope to God he never runs for office again.
Nearly half of voters say Biden worse president than expected, most don't want to see him run again: poll

CNN —
The federal government will no longer use the terms “Negro” and “Oriental” after President Barack Obama signed a bill into law.
Office Of Minority Economic Impact.
—Section 211(f)(1) of the Department of Energy Organization Act (42 U.S.C. 7141(f)(1)) is amended by striking “a Negro, Puerto Rican, American Indian, Eskimo, Oriental, or Aleut or is a Spanish speaking individual of Spanish descent” and inserting “Asian American, Native Hawaiian, a Pacific Islander, African American, Hispanic, Puerto Rican, Native American, or an Alaska Native”.
People might understand you better if you spoke English.
I used a similar reference back in the 90s regarding the boxer Lennox Lewis (sp) from England. Someone referred to him as African American. I said their is nothing American about him.The problem with this legislation is that terms like African American does not define one's race. For example, if we're say talking about the race of winners of track and field in the Olympics, you can't classify a Kenyan who won the marathon as African American. One's race doesn't change based upon where you live. That Kenyan is the same race as Jesse Owens.
You know when your're pinned down and want a look without risking your head? There are ways to minimize your shake so you can something besides a blur from a periscope attached to your head. The new generations didn't grow up with mechanical stuff - they grew up with computers, and they don't understand mechanical concepts. Old guys knew things - new guys don't - even if some of them seem pretty obvious. Engineering like a lot of stuff can can be "mastered" from books and courses - it just doesn't make for good engineers - those are the guys who grew up with hands on experience taking stuff apart, repairing it, getting a feel for what makes things tick. Problem is you can't do that today, and Legos only go so far as a teaching tool.
I'm wondering when cars and airplanes are basically turned into drones - point and shoot and the car handles calculations to make sure it gets around a curve. That's when we lose all the sense of touch, perception, etc that makes some people drivers and others accidents in waiting. That's what all the reliance on toys and apps is doing to us - multiplication tables and practice vs punching buttons on a phone or calculator (assuming they still exist) - and what happens when the toys die for lack of power or an EMP. Sorry, carried away.
