There are a lot of idiots enraged by this misleading Times headline.
The article itself - yes, the exact same one - points out that:
A) In any typical year, about 50 independent schools close
B) More independent schools opened than shut, so the overall number went up.
But that's far too nuanced.
Now more than ever people need to know the basics of #solar and #wind energy, here is my #physics explanation (at a basic level).

I think it's just a different understanding of "unit conversion factor". The original poster is saying that h is a constant with appropriate dimensions to convert frequency to joules.
28.07.2025 20:04 β π 1 π 0 π¬ 1 π 0h is in m^2kgs^-1 so hf is kgm^2s^-2 and E is in Nm where N is kgms^-2 so E is also kgm^2s^-2

After years of teaching quantum, I just realized that I have gotten this equation, at the heart of QM, backwards. Itβs not saying that the frequency f of a particleβs wave function is given by its energy E. Itβs saying that energy is *defined* as the frequency of the wave function. βοΈπ§ͺ (1/4)
