Walkers for Wobbly Bits

My other half is rather odd.  He supports Walkers for Wobbly Bits (my Susan G Komen Race for the Cure team).  This is totally divergent from his usual interests, which include:

  • His 1965 Ford F100 pickup truck, a.k.a. The Beast. This creature technically belongs to both of us – communal property and all that – but my partial ownership seems to have been forgotten over the years.

A Pythagorean Problem

There is no mathematical theorem used more in my daily life than the Pythagorean Theorem.  Even my non-mathematical friends make second-hand use of the theorem by calling me with a query about how much material they need for a project involving a triangle (or a shape that approximates a triangle).

I am past my prime…

I am past my prime.  Yesterday, I was not.

With the passage of just one day, I’m a year older.  What a cruel trick!  Surely it’s a mathematical impossibility.

How can time contract so? Am I living in a gravitational anomaly?

Yesterday, I was the product of two prime numbers.  Today, I’m the cumbersome product of an unlucky number and the square of a prime number.  It’s a demotion, for sure – and an awfully inelegant piece of arithmetic!

However, next year I will return to my prime, as I will in 7 years and in 9 years time.  Getting older gives me something to look forward to!

Wimpy Woman

For some reason or the other, I never included pull-ups in my exercise routine until my early forties.  With a modest degree of effort, I was soon able to complete three sequential pull ups. Although I was rather proud of myself, my offspring remained peculiarly unimpressed by my stupendous achievement.

Now ten years later, and despite exceedingly diligent efforts, I can’t even complete one pull-up.

What has this to do with my career in engineering? Read More

Classic Science Fiction

Every ninny should read these books –

Frankenstein by Mary Shelley:

Although generally designated a horror story – and it does have Gothic elements – this book is clearly science fiction.  The novel is the prototypical cautionary tale of science running amok, and I struggle to think of an earlier example of the genre. Read More

Pondering π

Pi is such a lovely little thing.  It’s shape (π) could easily be mistaken for an Ikea-designed seat, structured – oh so elegantly – to support our posterior.

Isn’t it remarkable that this delightfully formed Greek letter has come to mean so much more than its place in the alphabet warrants? Read More

Are you a numerate ninny?

How does your mind work?

When you see rain on a windowpane, do you estimate the number of drops per unit area? Do you stare at your dryer because it’s such fun to watch it tossing clothes? When you rub your aching feet, do you compare your instep to the structure of classic stone arches? Do you look at the curve of a petal and wonder which quadratic function would fit it best?
