With the Cosmic Web in Mind..

Some time ago I posted one of my Astronomy Look-alikes about the remarkable similarity between the structure of the human brain and that revealed by computer simulations of the large-scale structure of the Universe:

I wonder whether this means that the Cosmic Web is really just all in the mind?

Anyway I just came across an article by Franco Vazza and Alberto Fenetti that takes the comparison between brain cells (among other things) and the Cosmic Web a bit further, including a look at the corresponding power spectra:

The main point to take from this picture is that many naturally occurring patterns have approximately power-law power spectra, at least over a limited range of scales. However, as I have pointed out before on this blog, the power spectrum on its own does not really quantify pattern in any meaningful way. Here for example are two patterns with exactly the same power spectrum:

The point is that the power spectrum does not contain any information about the phase correlations of the Fourier modes, which are important in quantifying localised features. For further discussion of this issue, see here.

TV Star and Physicist Look-alike?

My attention was drawn yesterday to this remarkable photograph of a very young Professor Brian Cox, the famous particle physicist turned astronomer biologist and media star. I believe it was taken while he was a member of a popular beat combo of some sort. Before seeing this picture I hadn’t realized what people meant when they referred to him as a TV celebrity ….

…geddit? Anyway, I have to say I think the look rather suits him!

I haven’t got time today to trawl the interwebs looking for a lookey-likey, so it’s time for a bit of crowd-sourcing. Anyone care to suggest a celebrity likeness?

P.S. I have done a look-alike for Prof. Cox already.

It appears that Newcastle United Football Club have appointed our own Rob Tucker as their new manager!

Astronomy Look-alikes, No. 40

Obviously someone else has already noticed the remarkable similarity between the structure of the human brain and that revealed by computer simulations of the large-scale structure of the Universe.

Does this mean that dark matter is really just all in the mind?

Baroness Gaga

While I’m on the subject of look-alikes, I couldn’t help noticing the resemblance between Baroness Susan Greenfield, former Director of the Royal Institution, and popular American recording artist Lady Gaga. I wonder if by any chance they might be related?

Grandmother and granddaughter perhaps?
