I am very new to the world of CS but I appreciate precise vocabulary. Is my understanding below correct?

• Sorting = Assigning each object to one category (“bin”).

• Ordering = Like sorting, but the categories themselves have an inherent hierarchy/order (numerical, alphabetical, etc.)

And leeches. Can’t forget the leeches.

Doctors HATE this simple fifth lesson!

I hope no mad scientist ever plays with that gene 😅

No mad scientists, just regular scientists working on regular fruit flies. What could go wrong?

These sets of concentric shells contain a thin layer of positive mass tucked inside an outer layer of negative mass.

So how much evidence is there for negative mass, then? Sounds like just replacing one unknown with another.

This is the third time this year that I have come across this. I am pissed that it was never taught in school… and that apparently I keep forgetting it every time.

Thank you for taking the time to write it out! Funnily enough I’m not too bad at math (I tapped out at around linear algebra level) but I was taught in a very rigid way. Useful concepts like commutativity were just… read out loud to kids to be remembered as a Law Of Nature, instead of allowing kids to play with numbers and develop our numbers intuition. So while I have a decent theoretical knowledge, I’m terrible at applying what I know to real life. If that makes any sense?

Also, if you have any tricks for teaching percentages, ratios and basic statistics PLEASE SHARE. My partner has a new job and while he shines at the field work aspect, he has trouble with the mathier parts. He’s had godawful terrible teachers his whole life. I’ve tried coaching him in math but my methods don’t click with him. We also don’t have the time to wade through dozens of YouTube videos hoping to hit the holy grail…

I think that fear is just one of the many responses humans like to stimulate. Spicy foods and deep massages? Fancy pain. Fireworks and laser shows? Fancy lights and colors. I wonder if it ties into the ability to remember that we survived the painful stimulus long enough to enjoy the aftermath, so we’re more likely to seek out that stimulus in the future? High risk = high reward kind of thing.

Wearing super preppy clothes to school/college. I was mistaken for a teacher in 11th grade. In college, I once wore a pencil skirt, black tights, white sweater, and high heels… to a regular Tuesday afternoon class, just because I wanted to.
