Bartolome Esteban Murillo barefoot

Yesterday was Bartolome Esteban Murillo's 400'th birthday, so says Google - liking the image in the Doodle I checked up on the man and found a wealth of beauty in his pictures particularly of children, and also an intimate knowledge of bare feet.

Now take a closer look at those feet. The dirt, the calluses, the cracks - I know them well - they could easily have been my feet!  I'd like to know what he used as balm to heal those cracks?


Amazing detail in these feet

Look at the detail in the clothes

Check out those feet again!

Euler



Euler, mathematician par excellence

In spite of what people say, I am not a mathematician. This is evident in that I can't play a decent game of chess. I enjoyed and excelled at O and A level maths but became unstuck at college level with divs and curls and wot-not.  And so I cannot eulogise over Euler as befits him.  A statement attributed to Pierre-Simon Laplace, another master in mathematics, expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all."

But I do remember my fascination on meeting Euler's famous formula for the first time in PSS days

e^{ix} = \cos x + i\sin x \

which brought together so many threads in the A level maths syllabus - convergent series, imaginary numbers, trigonometry, logarithms and exponentials - just as the diverse characters are in the last chapter of a crime novel.  Substituting  pi for x we have the identity shown in the bottom right of yesterday's Google doodle:
