It's all Greek to me by Duncan Waldron

Some years ago, I had to photograph academics doing their thing. I found a print of the job recently, and thought the formula looked interesting. The main protagonist tells me:

The maths describes the clustering of high points in the density field. At the time, we thought galaxies might form there (in some circumstances, we still do).”

And I watched him write it out, without his having to use a cheat sheet; you don’t become Professor for nothing.

    ha ha ha …!!!!!
    For me too..
    Is that the Einstein´s Relativity Formulae?
    This is apt for recalcitrants physics students…
    je je je.

  • It’s something a lecturer wrote, when I need a photo showing academics at work. Don’t know what it means! Probably something about stars revolving around a galaxy centre, stirring up dust, and generating heat.

    Looks like a Fourier Transform of the dirac delta function in R squared space, which is the physicist’s screw driver for going backwards in time. What class was this? Or was is his research? Do you happen to know?

  • You’re better informed than I am, Kelly – I wouldn’t know a Fourier Transform from a Ford Transit! This was a situation where I had to provide a photo of a scientist, so asked Alan to oblige, with a handy PhD student. I just asked him to scribble something interesting on the whiteboard; I guess it was in some way associated with his research or teaching.
