Astronomy Look-alikes No. 100

Posted in Astronomy Lookalikes, Cardiff, Television with tags , , , on September 16, 2020 by telescoper

I haven’t done any of these for a while, but last night I was surprised to see Professor Jane Greaves of Cardiff University on television for the second time in a week so I couldn’t resist. I wonder how while discovering phosphine in the atmosphere of Venus she finds the time to play Detective Chief Inspector Vera Stanhope in the popular detective series Vera?

Astronomy Look-alikes No. 99

Posted in Astronomy Lookalikes with tags , on April 10, 2020 by telescoper

I’m aware that it has been some time since I posted one of my Astronomy Look-alikes but I received the following suggestion by email from an anonymous correspondent following a post earlier this week.

The email reads:

Have you noticed the striking resemblance between the well known blogger and observational cosmologist Ricky Tomlinson and the acclaimed actor and icon of working class manhood, Peter Coles?

Disturbingly, the latter has been seen recently impersonating Tomlinson in an on-line Maynooth University Computational Physics lecture.

My correspondent has obviously let social isolation get the better of him, because everyone knows that Ricky Tomlinson is a theoretical rather than observational cosmologist. Moreover, although he does look a little bit like me, I obviously look nothing like him.

Anyways, if you’ve got nothing better to do please feel free to send me further suggestions for the Astronomy Look-alikes folder!

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.

It has been pointed out to me that I haven’t contributed anything to my collection of Astronomy Lookalikes recently. My only excuse is that I haven’t really thought of any. I’ll try to get it going again. Suggestions are always welcome.

In the meantime take a look at this book look-alike:

If you click on the picture you can make it bigger.

These two pages are taken from two different books on Astrophysics written about a decade apart by two different authors. This is by no means the only point of similarity between these particular volumes. I wonder if by any chance they might be related?

I couldn’t possibly comment.

Astronomy Look-alikes, No. 98

I’ve been reminded that it has been a while since I last posted an Astronomy Look-alike so I was wondering if anyone else has noticed the spectacular similarity between Professor Will Percival of the University of Portsmouth and TV presenter Richard Osman? Is it pointless to ask whether they might possibly be related?


Astronomy Look-alikes, No. 97

I found an appropriate look-alike for University of California at Berkeley astronomer and serial sexual harasser Geoff Marcy:

Heavens above!

It has been drawn to my attention that there is a remarkable similarity in visual appearance between planetary astronomer Albert Einstein and the creator of the theory of general relativity Jean-Pierre Bibring. I wonder if, by any chance, they might be related?





Astronomy Look-alikes, No. 95

I wonder if anyone else has noticed the resemblance between Coel Hellier, Founder and Head of International Rescue, and Jeff Tracey, Professor of Astrophysics at Keele University? Thunderbirds are go!

Perhaps the UK space programme could benefit significantly from the assistance of his organisation?


Astronomy Look-alikes, No. 94

I’m struck by the similarity in visual appearance between distinguished astrophysicist Herr Professor Dr Auric Goldfinger and infamous Bond villain Reinhard Genzel. I wonder if by any chance they might be related?


Astronomy Look-alikes, No. 93

I’m struck by the similarity between astronomer Karl Glazebrook of Swinburne University, Melbourne (in Australia) and comedian Peter Kay from Lancashire (in the Midlands). I wonder if by any chance they might be related?
