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.

I just like to say my name is Sydney. " And what's your last name?". Me:" Australia". Sydney Australia.

Climbing out your window? Spider Woman?

How I impressed this French woman. She asks me " Do you like Le Pen?". I reply " Yes, but I prefer Le Pencil".

Her work long overlooked, physicist Joan Curran developed technology to conceal aircraft from radar during World War II

The actress Hedy Lamar conceived of the idea of

Frequency-hopping spread spectrum[edit]​

Copy of U.S. patent for "Secret Communication System"
During World War II, Lamarr learned that radio-controlled torpedoes, an emerging technology in naval war, could easily be jammed and set off course.[52] She thought of creating a frequency-hopping signal that could not be tracked or jammed. She conceived an idea and contacted her friend, composer and pianist George Antheil, to help her implement it.[4] Together they developed a device for doing that, when he succeeded by synchronizing a miniaturized player-piano mechanism with radio signals.[40] They drafted designs for the frequency-hopping system, which they patented.[53][54] Antheil recalled:
https://en.wikipedia.org/wiki/Hedy_Lamarr#Frequency-hopping_spread_spectrum

But I most admire Hedy for not only being the first woman to do a nude scene in a movie, but also her love of older men. :)

She once explained that she was tricked into doing the nude scene in the movie. She was told it would be a very distant shot and no one would be able to see anything but a shape, which was partly true. But she didn't know about the new technology referred to as telephoto lenses...

... That's "Hedly" :)

A nice way of showing not all quadratics have a Real solution. Let n>1. Let p be a prime. Then n(n+1)=p cannot have a solution for n>1, else n divides p, a contradiction .

Then n(n+1)=p, so that $n^2-n-p=0 \rightarrow x^2-x-p=0$ cannot have a Real solution. I mean, any integer not a product of consecutive numbers would work too, but the prime makes it cleaner.

Not an amazing argument, but seemed nice.

Whaaaaaaaaat?

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.

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.

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.

 

[Bystander]

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."

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

 

[BillTre]

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.

 

[Ivan Seeking]

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.

 

[WWGD]

Ok, Cost function, not Cos(t). That helps.

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.

And I hear your take was glowing . Just like with Homer ;).

The line " What are you wearing" does not seem as effective in person.

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.
