JN -- more I want to keep my language unambiguous and courteous disagreement so when I want to be truly grouchy, I have the dynamic range in language to go there. 😉
In other words, we're good.
Edit-- yeah, Bill, my correction was to avoid that being the interpretation!

I used to work in destructionless material testing, mostly with ultrasonics, on the inner enclosure of nuclear reactors, and later on gas pipelines, and stumbled across the sentence that the rupture of a 48" gas pipeline usually creates a crater 50 meters in diameter. It seems that has happened often enough that they could do statistics 😱 The pumping stations are 50 Km or so apart, therefore a volume of 48" dia * 50 Km length is lost. It burns normally, probably a lot of roasted elks there in Canada.

Putting half a dozen of people on the ignore list makes this thread almost readable.
I remember reading (Nature?) about filaments forming in water, chain like structures. Any clue to shake up this old brain would be welcome.
This is not it, but all I got Googling Dynamics of water filaments in disordered environments. - PubMed - NCBI
The physics of passing water would convince everyone about the contrary. What intelligent designer would get the idea to wrap the prostate gland around the ureter? And then make it grow forever?
Life, at least the basic units, must have been engineered. Which is not quite the same as having been intelligently designed.

That was the 20th century.
Nowaday, people just use pay per use, ready to run services in the cloud made of those blocks of code.
I'm not saying it's bad...
The problem that most of the many old men here will face sooner or later is more that they can't get rid of the loo any more.
I'm sure it is, and not only at MIT. However, at MIT, the basics are still taught in 6.01 "Introduction to EECS".
Hands-on, in Theory and Practice | MIT EECS
I agree that today EE undergraduate studies are a hodge-podge of topics which deliver an undergraduate with expertise in everything and nothing at the same time. I guess the line between undergraduate and master levels is drawn in the wrong place. Not sure what kind of job could even a MIT undergrad get today, IMO the curriculum only proves he's able to learn effectively (and to pay the tuition 😀), skills for any EE job are virtually zero.
Second year of undergrad I was taught Solid State Device Physics, third year Circuits and Systems (big on feedback, filters, synthesis, etc...) fourth year was Information Theory (Shannon, entropy, coding theory, channel capacity, etc...), all mandatory. 90% of this is today at graduate level, mostly electives.
I was watching the PBS program on the Moon landing anniversary, Buzz Aldrin said he did not crap for the whole trip to the moon and back. Maybe the lack of gravity helped because he despised the extraction device.

There were no robots when I took 6.01 nothing but the basics. It's where I learned the MIT way, the midterm had a problem with an ambiguous answer the prof admitted that my answer was valid but the wrong one so it was a good time to learn the MIT way.
Business class, unlikely. 😀
I suppose the requirement in general to design or stabilize an analog domain system with feedback using math and real components is rapidly coming to an end. It’s all digital now with PID control blocks you can embed in code and often thr6 are self tuning. So indeed, it’s Asimov’s ‘Profession’ but this type of thing is repeated in almost all disciplines, not just EE. Seems the more we progress, and the more complex our systems become, the further we move away from the fundamentals.
Maybe he just spoke it instead?

I often wonder why the beer I drink taste totally differnt depending on the glass I'm drinking it from. Especially after judging for 5 odd years after diagnosis and developing a keen sense of the nuanced perspective of aromaticity (especially Citra), having homebrewed oh... 25 years or so.
I've noticed also that almost all of the Grateful dead music (which I like) has a flat presentation, very lacking in ambiance and depth, compared to say Little Feat.... whether processed thru all sorts of electronical and hyper-space machinations, it's still flat. Not bad, I just focus on the execution as opposed to the realism.
Back to beer, my latest Weinstephaner hefe clone has unique banana and clove overtones, along with that funky yeast character from Belgium we all love and lust after, eh?
However, when I drink it from a flute, it seems to exhibit a sparkling champagne-like character, with brut-ish overtones, and a crisp finish. But If I drink it from a stein, it tastes like it came from Heidelberg, with Cologne-like smoothness and a flowery mid-palate.
What's going on here? :-;

Well, "we" are getting old. "They" know better today, probably as much as "we" knew better yesteday from those that studied vacuum devices.
Although I got myself a good bite of klistrons and magnetrons in the masters years 😀. Hated them ever after 😀.
Here here!!! On one of those infernal heavier than air tin cans, there is no such thing as too much drinking. 😱
I am not a good flyer.

Yes, IME I find that the materials that the vessel is made from influences equilibrium constants, or 'energies' or something..,....tea/coffee in a glass cup tastes different to the same brew in a ceramic cup. Soy milk/fruit juice comes in aluminium foil lined cartons and tastes quite different according to standing time in a drinking glass. JC has a drinks coaster that alters the taste of his Cognac, I have a 'similar' treatment that alters the flavour of wines.....or soy milk, juice or water.
As Auplater asks, What's going on here?.
Dan.
Joe's compensating networks (Zobel networks) are in parallel with crossover input and not crossover output......this is quite different to usual/standard implementation across driver terminals.
Dan.
Well, I’m pretty sure it’s well known the shape of the glass has an effect on what you smell, which could impact your perception of taste. As far as a coaster, I’m not buying it.
And it seems that just this morning we did not agree😀.
I am not the cat's meow when it comes to motion control. But it concerns me that I have to explain to "seasoned" engineers what gain and phase margin are...why a motor magfield force profile is non linear, how the phase margin is force dependent, why insertion of a second order filter in the control stream lowers phase margin and stability.. When they cannot even understand the fundamentals behind the explanation, there is a problem!!
The motion control vendors are dumbing down their tuning teachings to the point that the endpoint product is just garbage. And people wonder why I do not like flying...
Even here, the discussion of amp and speaker impedance...really? What happened to sqr(-1) and calculus???
The previous was not a rant....not even close.
