Yes I say wave maker sometimes. Also, I'm always a little wary when mentioning Kundt's Tube.

15.02.2025 13:34 β π 1 π 0 π¬ 1 π 0I don't know enough to answer but I believe that there are different types of altimeters and I presume that they operate under different formulae which likely lead to discrepancies.
15.02.2025 13:29 β π 0 π 0 π¬ 2 π 0This is so true. The assumption that learning facts and the ability to think creatively are mutually exclusive is bandied about in education circles. There isn't enough time to learn everything by discovery. We have to learn from those who have lived before us.

I have to admit I've never wondered about the precision of this measurement until now. I'm reminded though of LC Maths 2012 Q9 on that topic which compared two formulas.

I have tried Chat gpt to make maths worksheets and on the surface they looked good but you run into issues when you try to solve the problems.
