#Physics We have kinematics equations for constant acceleration, often called SUVAT - essentially vectorial, but (efficiency / laziness?) commonly written without explicitly indicating this.

"s̲", represents displacement. "v̲" velocity.

So, we're left with "d" for (scalar) "distance" but... speed?

Often, "v" is used. But this commonly represents the magnitude of the related v̲, the velocity.

AND a key point is they're not always the same i.e. if we take the average.

So, suggestions for speed?

#Mathematics The intro of i = √(-1) is commonly motivated by its historical appearance in solving polynomials.

Veritasium did (IMO) a nice explanation of this.

However, for more technical detail/perspectives etc. (but skimming the history) Mathologer's better:

I emphasise to students there's no perfect resource. Consult multiple, to improve understanding etc.

Do you know of other nice resources on this topic (similar level).

Light is like a wave, and sometimes it's like a particle, but actually it's both... but neither... it's its own thing.

[Also fulfilling my desire to naturally use "it's its" in a sentence.]

What evil person put an odd number of dog treats in a bag? The dogs are looking at me like it's my fault!

Fortunately I learnt of the wisdom of Solomon, and so... the solution was simple, I cut a baby in half... I mean, I cut the dog treat in half.

As the OP knows, there are plenty of inaccuracies in this (see the comments). But it makes a point.

I'm so far from a "prepper" that we live on different planets... but I do have a map book in my car for when GPS "inevitably" goes down.

Anyone else... or is this just me?

2. You can tap students on the shoulder but in the end it has to be voluntary.

3. Each week they can choose to attend, or not, for that week.

4. No official assessment or any other administrivia.

5. No curriculum, we do whatever we feel like.

This year we have 5-8 students choosing Specialist Maths. 2/2

#Mathematics

At our high school, for two years in a row, we had NO students pick the "advanced" mathematics stream (locally called Specialist Maths).

I explained in various ways why this was. So then, this year, someone asked me to put "my money where my mouth is". So I said sure, give me some of the Year 10 math students (the year they're making their choices) for one period a week but...

1. It's release from their regular maths class (no extra time commitment).
