Good choices all.

I'm thinking along a theme Reflections on erreurs du couer, to effect "I'll never get into heaven all my Mother-In-Law's are there".

Well, I kind of failed real analysis, and I got a C- in complex analysis, so... my grades just aren't high enough to get in, honestly. And I hated both of those classes. I got an A in physics though. I might try to go for statistics or do a minor in physics or something. I like math, but the math major is just making me miserable.

Ah, I see. I'm at my limits of what I can advise, perhaps someone else cares to chime in?

Anders Celsius. Can you guess what I learned by the name?

I also learned
But hey, I don't blame him. My logic would have told me same. I would have hypotethized: "I think the rise is due to evaporation... But how can I experiment and test?" Logic can be wrong.

Today I unfortunately learned how hot a soldering iron truly is. On the bright side I now know how to use a soldering iron and the importance of always wearing protection.

LOL. When I was about 10 years old, I was learning how to solder using a Weller Soldering Gun, and I wondered to myself whether the shiny rods that hold the tip were hot. Yep, they were!!!

Today I learned two things about dribbling my new basketball down the hall at work (do not ask me why I am at work on a Holiday weekend, and don't ask why I'm dribbling down the hall please...)

We have a nice thin springy carpet at my work, and surprisingly, the basketball rebounds up about 20% higher than it does on hard asphalt or concrete. I did not expect that!

And it turns out dribbling a basketball down the hall on this type of carpet generates a huge amount of static electric buildup on the ball (and me, unfortunately). When I grabbed the doorknob to dribble out into the lobby, KABLAM!!! (must have been close to a 30kV shock!)

You're far too focused on it. Be careful, it's a high risk, very volatile investment and other forms already entered the stage.

Yeah, I agree. That boat has sailed already.

One can have a bigger foot than the other.

I started measuring my feet and noticed that one measurement was larger than the other and I was like: "This cannot be, I must be doing something wrong." Although the difference wasn't much.

I spent half an hour measuring my feet again and again until someone told me that people can have one foot bigger than the other.

That moment when you think you are doing something wrong, but you are not.

TIL (through experimentation and observation) that no matter how long you spend working on an essay, you can never determine how it's going to be received.

We recently had a couple of dense showers of dry little balls of snow, smaller than a pea and white rather than clear ice, falling slower than normal hail, resembling tiny little balls of snow, landing quietly and looking very similar to some polystyrene packaging beads. I didn't know what to call it, so I searched online for an appropriate term. Today I learned that the correct term is "graupel", a term of which I was previously unaware, and it is also sometimes described as soft hail.

I also learned that the term "sleet" (which here in the UK means a slushy wet mixture of rain and snow) is used in other places such as the USA and Canada as a general term for precipitation in the form of ice pellets.

Yep. We actually use "sleet" to refer to both.

TIL that things can explode in a microwave.

Before you laugh and write things like "I could have told you", I bet you wouldn't had expected to be goulash in that category either!
