The Beauty of Maths and the Number 27

I sure love the magic and beauty of numbers. Everything is numbers! Maths is everywhere! Patterns appear in nature, in structures around the world and even in distant galaxies.

Bertrand Russell expressed his sense of mathematical beauty in these words:

Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as poetry.

Twenty-seven is a perfect cube, being 3^3 = 3x3x3 and is the result of adding together the integers from 2 to 7 (2+3+4+5+6+7=27). It is also the only positive integer that is 3 times the sum of its digits (3x(2+7)). And 27 is the number of bones in the human hand.

In astronomy, Messier 27 (M27) is the magnificent planetary nebula otherwise known as the ‘Dumbbell Nebula’ and was the first planetary nebula to be discovered; in 1764 by Charles Messier from whom the catalogue bears his name. (See Featured image. Credit: ESO)

And finally 27 is the Expedition number which was Italian astronaut, Paolo Nespoli’s second spaceflight. I have had the great fortunate of meeting him several times, including a Mission X opening event, Farnborough International Airshow, International Space University and he even appeared in a video appearance for us for the UKSEDS 25th Anniversary conference last year. From Expedition 26/27 he filmed the majority of the footage for the documentary film First Orbit, filming the view Yuri Gagarin saw on his pioneering orbital space flight. Paolo also captured many beautiful images during his mission, named MagISStra.

So why the number 27? Well, today is my 27th birthday!

Of course, I’m not going to argue with the great Sheldon Cooper from The Big Bang Theory that the best number is in fact 73.
