But a simple altitude string would be impractical, I think.

My learning strategies are very personal, subtle, and hard to explain. I believe I build most of them a long time ago after reading Mind over Machine [1]. It's a critique of the, back then, glorious promises of AI, but it has a very th

As a student or teacher? I've had exactly this recurring dream, forgetting to teach a class. What a nightmare when they are not ready for the exam.

Apparently it's neither intended nor used as an "impossible/trivial" problem: The interviews were an in-depth back-and-forth discussion, as much as could be had in about 25 minutes. These interviews, of course, are just

I'll buy that, if you mean 'more than 50% of the information, that can be gleaned when watching at 1x speed, can be gleaned when watching at 2x speed'.

I remember a rather comprehensive online pdf manual/book back in '99 when I went Clean for a period.

Open source! In the old days when taking off the lid or back plate you would find a full schematic of the analogue computer inside inside.

So that's the real reason tobacco taxes rise; the number of smokers decline.

The increased distance between the two points of measurement to be compared would also complicate matters.

This really demonstrates the technical orthogonality between the mainframe and the micro/mini world. A tremendous effort to channel Unix'y behavior all the way to and from the user terminal. At the time I was involved in designing

I found out when I was young too. I guess it's just curiosity about how things really work. And then of course attention to the fine details. Really feeling what goes on.

You cannot make an overall lean. You can't just shift the center of mass. What happens is that you angle your upper body relative to the bike. If your upper body leans left, the bike leans right. If a bike running hands free leans, the

It depends on what "easy" actually refers to. When we say it's easier to program in language X than language Y, we don't speak about the cleverness behind the X compiler. The author thinks that his way to "code&quot

Right, but this just describes how to use this variant of the more standard formula. What is interesting is how do you derive the formula.

No he should not. The words invokes the right connotations in a pedagogically minded reader. This can be the basis for better teaching. It depends of course on implementation.

Pedagogically there's more to it than just the algebraic manipulations. The algebra here is basically as dull as all other algebra. It's the teacher's job to make it come alive.

That's ok. I can't explain it here in a few lines. It's rather a pedagogic principle that permeates most of my teaching. It's not just a postulate. It's demonstrated. A style used from the start of algebra.

This is not about deep math. It's about pedagogics. How to generate some understanding and good feelings for solving quadratic equations.

It can be obvious in other ways. For example if you can see how a parabola is the product of two straight lines. And you can teach it that way.

I taught it this way in homeschooling with heavy support of graph-geometric intuition, drawing and looking at various parabolas. Works great.
