The discussion revolves around frustrations with current documentary programming, particularly criticizing the History Channel's focus on sensational topics like time travel conspiracies instead of real historical content. Participants express disappointment over National Geographic's sale to Fox, fearing a decline in quality programming. The conversation shifts to lighter topics, including humorous anecdotes about everyday life, such as a malfunctioning kitchen fan discovered to be blocked by installation instructions. There are also discussions about the challenges of understanding various dialects in Belgium, the complexities of language, and personal experiences with weather and housing in California. Members share their thoughts on food, including a peculiar dish of zucchini pancakes served with strawberry yogurt, and delve into mathematical concepts related to sandwich cutting and the properties of numbers. The thread captures a blend of serious commentary and lighthearted banter, reflecting a diverse range of interests and perspectives among participants.

For those unaware, there is a meme that people who pretend to be smart (/r/iamverysmart) almost always state "quantum mechanics" as an interest.

NO ONE WHO ACTUALLY STUDIES QUANTUM MECHANICS FEELS SMART STUDYING QUANTUM MECHANICS.

If your solutions seems elegant and intuitive, you definitely made a mistake.

I remember my first senior QM course so very well. I would read the chapter and sit through the lecture and it all made perfect sense. Then when I got to the homework problems, I thought I must have studied the wrong chapter. :olduhh:

So, what is it with the double negatives here. I don't understand it (never studied it beyond the most basic). Does that imply I actually understand it? Looks like an Abbot and Costello routine:
Abbot: I am in First Base and I don't understand QM.
Costello: No, I thinks I understands QM and I is in Second.
Ebonics Translate: You mean I be in Second and I be not understand QM?

Generally, you can no longer conceptualize the subject. It becomes purely mathematical.

That's why philosophers have been arguing about the implications for almost a century now.

And if they make sense when you've been drinking, they probably don't make sense.

When you take an exam in it, if you get more than one right, that's an F --because you seemingly understood something.

Citrin tastes like soap...or so the story goes (does to me anyway); this has been "cited" as an explanation of the "aversion" to citrin spiced cuisine among an unknown sized group of people/gourmets/gourmands. Just did a little browsing, and could find no mention of this factoid/folklore/old wive's tale/"everybody knows that" ancient common knowledge.

Was in pursuit of an explanation for the gasoline/kerosene/coal oil flavor of artificial "sweeteners."

Even Physics got me a date once. I was 19 years old and living in a cheap apartment with a friend. While sitting by the closed pool reading a physics book, a beautiful young Mexican woman who could barely speak any English, came up to me and indicated that she wanted to know what I'm reading. I said hello and showed her the page I was reading, which of course was filled with equations. She looked at me wide-eyed and said in broken English, "Ooooooh, you must be smart!" We dated for the next several months even though we could barely talk to each other. But we always managed to find something to do. LOL

Only as I found her climbing out my window one morning did I learn that she lived in our apartment complex with her boyfriend - the dangerous-looking biker dude.

Ironically, her name was Lourdes.

Ok, Glue on Nails. Not Gluon Nails. Now it makes sense.

Some nails have a coating of plastic that melts from the heat generated when they are hammered in.
Its like hot glue gun glue.

Hammering and Scolding-hot glue? Yikes.

Reminiscent of spin welding, which is used for metals as well as plastics.

Spin welding is used on the thousands of alignment pins used for many parts for commercial aircraft assemblies.

I was concerned when I first heard about Nuclear Visine. Radioactive eye drops didn't seem like a good idea. So you can imagine my relief when I saw an ad for New Clear Visine.

It seems that some people are afraid of nuclear magnetic resonance imaging.

That's why they changed the name to MRI for medical scans - Magnet Resonance Imaging. I was working on NMR imaging scanners when they first came out. But they soon became MRI.

No but it did nearly take off my arm once. Someone had put a regular metal chair onboard that looked just like the stainless steel chairs. I slung my arm through and walked back to make an adjustment at the magnet. By the time I felt the tug of the magnetic field on the chair, I was airborne.

Ouch! I got locked out of a Python Jupyter file. I wrote a simple * algorithm to spit out all primes between 2 and10000. It had an incorrect loop and looped for who knows how long. I saved it , including the output repeated (looped) who knows how many times, to the tune of ending up being 99MB in size, which is larger than Jupyter Notebook can handle without ending on its knees. Still buffering after 45 minutes. May have to try to open as a .txt file or something.* And incorrect, obviously

Is it a coincidence thin Germans I know are called Dieter. You diet, you lose weight. And some mention stays at a Gymnasium as well.
