Right. I've entered a half marathon (for the first time in my life!) on 12th October and am raising money for Cancer UK. If you'd like to donate great, if not, please share the link :)

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.

I have teeth related dreams (being able to pull them out and put them back in) on a regular basis, and have done for as long as I can remember. I've had loads of dental problems so probably not surprising for me - but I didn't realise how common they were, or the possible reasons behind them.

I want to tell you something about my Doctor Who book.

If you open it, you'll find it's dedicated to Katrina.

Katrina was a friend of mine with profound intellectual disability, which came bundled with a whole bunch of physical disabilities.

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.

h 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

Equation in large font reading "E=f"

Equation in large font reading "E=f"

After years of teaching quantum, I just realized that I have gotten this equation, at the heart of QM, backwards. It’s not saying that the frequency f of a particle’s wave function is given by its energy E. It’s saying that energy is *defined* as the frequency of the wave function. βš›οΈπŸ§ͺ (1/4)
