Colin Maclaurin and Grefriar's Kirkyard

Yea!  Technical difficulties are at bay for the moment!  Now this can go up!

The day before yesterday I posed a "teaser" in anticipation of this post.  The teaser asked what Lord Voldemort (of the Harry Potter series) has to do with mathematician Colin Maclaurin.

Answer: They are buried in the same graveyard (but more on that later in the post).

Colin Maclaurin (1698-1746) was 11 years old when he entered the University of Glasgow in 1709.  He graduated with an MA degree three years later; his thesis was on gravity.  He became a professor of mathematics at age 19 - the youngest person in the world to have become a professor until his record was broken recently in 2008.  During trips to London he became acquainted with Sir Isaac Newton, who was quite impressed with him and helped pave the way for Maclaurin to take up a professorship at Edinburgh University.  Maclaurin is know for his work in algebra and geometry, the special case of the Taylor Series Polynomial that is named for him, and many other mathematical works.  He is also a founder of the Royal Society of Edinburgh.



One main thing I searched out relating to Colin Maclaurin was his grave, which I knew to be in Greyfriar's Kirkyard.  This was my first experience trying to find a single stone in a large cemetery without help - quite a task!!!  (As we saw in the John Playfair post, cemeteries and kirkyards out here have lists of "celebrities" buried inside.  Colin Maclaurin's name is about halfway down the list here.)


But where is he?


I found a lot of interesting things on the search - though I did hurry through, as it was getting dark and the closing hour wasn't posted on the gate.  It would have been a bitterly cold and tremendously creepy place to be stuck for the night!




And there were memento mori aplenty!


Where is he?



Aha!  There on the kirk wall, top right!

OK, so I've already gone on a tangent, but most of us first hear of Colin Maclaurin in calculus class, so I think I'm allowed a few tangents in this post!


More about Greyfriar's Kirkyard

TANGENT #1

Greyfriar's Kirkyard is famous for Greyfriar's Bobby, a Skye Terrier who reportedly spent 14 years at the grave of his master, John Gray.  Here is a sculpture of him taken "from life" not long before he died on January 14, 1872.  Below this image is a picture of his grave, which is just outside the actual kirkyard - hallowed ground, so people only.  At first when I saw the things that were left at his tombstone it struck me as messy and disrespectful - looked junky at first glance - not flowers and notes, but sticks and and an old boot - until I realized they were fetching sticks, a boot to chew on, etc. - very appropriate for a dog.  As you can see in the picture below, everyone rubs his nose.  I did too!



Here is the church with Greyfriar's Bobby's tombstone in front.


The church is tucked away behind businesses - cafes, shops, etc. - which overlook the kirkyard, as you can see in a picture higher up in this post (the one just after the "celebrities board").



TANGENT #2

One of the restaurants overlooking this kirkyard is The Elephant House, which is where JK Rowling did much of her early writing on the Harry Potter series.  (I had lunch there today, and I hope to do a Harry Potter post if time allows.) She is known to have wandered through the kirkyard.  Just after I found Maclaurin's stone I overheard a couple of ladies in the distance who seemed to be having an interesting conversation, so I jumped in and asked what they were talking about (don't want to miss out on anything while I'm here - will probably never be back!).  That's how I learned of JK Rowlings wanderings here and that she likely drew on things here and nearby as inspiration.

Below is the tombstone of Tom Riddle, whose namesake now is Lord Voldemort.  I wonder what this gentleman who died in 1806 would make of that!



Thomas Riddle's Stone is certainly much simpler than what is seen in the Harry Potter movies, but if you combine this name with some of the stones posted earlier, the puzzle pieces of inspiration seem to fit.


We also have a McGonagall whose stone is diagonally opposite the Flodden Wall area of the cemetery.


Looking over the wall of the cemetery near the McGonagall grave is George Heriot's School, which is rumored to have inspired Hogwarts.


The name Potter also appears on a stone here and as the name of a nearby street and row (Potterrow).


I certainly got more than I bargained for - thinking I was only going to zip in and find Maclaurin's stone and head out - such a wealth of interesting things here!  (I guess that's what happens when you pursue mathematics, you find lots of interesting things on the side!)

Mathematicians of Edinburgh

When first planning these mathematical travels I had only planned a couple of days for Edinburgh.  My interest was in John Napier, a very interesting character who also invented logarithms and is responsible for popularizing the use of the decimal point.  After seeing Merchiston Tower, which is all that remains of his castle in Edinburgh and is now part of Edinburgh Napier University, and after touring Lauriston Castle, home of his brother, I was going to be on my way to my myriad of mathematical stops in England.

However, as I began to look into Edinburgh I became aware of more and more mathematicians and mathematical physicists of note who were associated in some way with Edinburgh.  Along with Napier, these are:

Girolamo Cardano
Colin MacLaurin
John Playfair
Mary Somerville
William Thompson, Lord Kelvin
James Clerk Maxwell
Peter Guthrie Tait

and, currently, Sir Michael Atiyah, geometer and Fields Medal winner.

Clearly my Edinburgh sojourn needed to be extended, and I ended up reserving six days in Edinburgh rather than the two I had initially planned.  Even at that I need to focus on two or three and just touch on the others.  In this post I am sharing landmarks that all of these mathematicians would have been familiar with - that's not to say that some changes may not have been made to certain places such as Edinburgh Castle and Holyrood Palace between the time of Napier (b. 1550) and Atiyah (b. 1929).

Post Script - this idea of common landscapes was confirmed today (March 31, 2016) when I visited the National Portrait Gallery and saw the piece below from 1820 showing Calton Hill and Arthur's Seat behind it.
