I still talk to people about this book at least once a month. It is such a great read and is incredibly eye-opening and thought-provoking. I can't recommend it to enough people.

That explains why the newscaster is imploring me to watch where the huskies go.

If you go out some night in a clear sky and just watch you will see dozens of them. It is infuriating.

We had a similar problem after changing the light bulb in the oven. The new one was to efficient ! I ended up going to thrift store to find an old 100w lightbulb that I use to heat the oven for making yogurt now.

The best way I have found to make it uncool is to say equals 42 immediately after and then launched into the discussion about how when we have two things next to each other we tend to imply multiplication. If you really want to continue you can discuss situations where addition is implied.

And states are passing laws that you cannot have fees for books, which sounds good, until you realize that it gives an excuse not have any books in the schools at all

Nice. I like the reinforcing division as repeated subtraction also.

Oh I don't take it personally! It's a valid point. I know language is important, what we say matters.

For example I've been trying very hard to say "our union" rather than "the union" because what we say can create lasting impressions.

I think sometimes his math teachers we lose sight of that.

I guess it is good too consider language more closely than I usually do. By saying job creator I gloss over that job destroyer aspect.

Language is important. I should do better.

13.11.2025 00:22 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Yeah definitely. I imagine that the number of jobs created versus the number of jobs destroyed is basically a wash.

Also I think that we as teachers help create people who can have and hold a job.

I definitely think that employment is not the point of education but economically it's important

I keep thinking about making a trillion dollars as a person. That would be enough to pay 16 million math teachers even if they are like me relatively high on the salary schedule. How is that possible?

I mean maybe he makes more jobs than I do but I don't think that he worth 16 million times me

NITARP - NASA/IPAC Teacher Archive Research Program NASA/IPAC Teacher Archive Research Program

This program helps teach teachers how to access all this NASA data and do real authentic research with their kids. It's amazing. It's one of the best development programs I've ever been a part of.

Can we agree that it could be even better if we had the exponent as

Has anyone ever fixed an old vacuum pump? The chem teacher was using mine and accidentally sheared off a valve. Oil and MERCURY!? poured out of it. I don't want to try to get a new one and would love to fix it if I can.

This whole thing is insane. I generally agree with no phones in the classroom as they are distracting and do lead to unfortunate incidents.

I don't know how does your school but the guidance is no phones but we have no policy beyond that and so it's a hodgepodge that doesn't work at all.

I was a bit distraught after the last election and feeling a bit helpless. Since then I have fallen into organizing for my local union. It is definitely helpful for my mind and my colleagues and my students. If you are feeling a bit lost consider organizing.

This is the sort of thing that is perfect for testing. With a class you can get a group to do each version and run it 200x and see the difference! That's my favorite way to show some of the weirdness that shows up in probability, and convince students to read closely!
