Non-math intents

[NSoiffer]

At the 18 Jan meeting, we came to a suggestion for a non-math concept that is definitely K12: "center of mass". There are undoubtedly many such concepts that have a (ambiguous) notation and hence likely to show up associated with MathML and need intent to be spoken semantically. Below is the beginning of a list of such concepts, broken into subject areas for clarity.

Please add to this list rather than adding new comments with suggestions.

Physics

• center-of-mass: $\bar{x} =\dfrac{m_1x_1+m_2x_2}{m_1+m_2}$
• anti-particle: $\bar{p}$ (similar for other particles, "e", ...)

Chemistry

• atomic-mass and isotopes notation
• electron and positron --the symbols are electron e to the minus one and positron e to the plus one.

Biology

Other

• arrows

I completed a review of a biology SAT prep book over the weekend. About a handful of new encounters:

I reviewed an Earth Science and an Intro to Engineering books this week:

Some interesting notational examples of concepts we have discussed so far, but not much that is new and domain-specific. Either we've covered a lot of ground in previous discussions, or the two books were a little too basic.

we have a process for adding chemical and other non-math intents: resolved to close 2024-05-16 meeting
