Dramatis persona*

helenhead Helen Chick

I've always wanted a bumper sticker that said "I'm a female, LDS/Mormon, Scout leading, geocaching, piano-playing, bicycling, mathematics educator with a PhD in maths ... and I VOTE"!

I think this makes me a minority group of cardinality 1!

* Since there's only one of me and "personae" is plural (I think), I've gone with dramatis persona.

Ramblings of a befuddled uber-pedant

Commutativity is a pretty important concept in mathematics. Addition is commutative, because, for example, it doesn’t matter which way around you add two numbers: 6+3 is just the same as 3+6. Multiplication is commutative too, since 5 x 4 = 4 x 5 (indeed, a x b = b x a, no matter the values of […]

Not a walk in the park

I had managed to organise my life so that I could do a caching run on the Anzac Day holiday (actually, my life is nowhere near that organised at all, but I decided I was going anyway). Jaffnut is a fellow cacher whom I’ve met before briefly, and she had suggested that, since there are some […]

A walk in the park

Wilson’s Prom National Park is a big reserve in Victoria full of spectacular coastal scenery, with mountains, beaches, wildlife and fantastic flora. It has wonderful beaches and lagoons, and it is particularly characterised by the granite boulders that dot the hills and define the coasts.

My oldest Scouts had decided to do their Adventurer Hike to Five […]

Not so much “A day in the life of … ” as “A door in the life of …”.

Alternatively, “These are the doors of our lives”.

Or, you could say it was an adoorable day.

Alternatively, you could skip the bad puns and just go and look at the photos.

Or you could skip this blog entry entirely, although […]

Landscapes and skyscapes

While we were away over the geocaching weekend we got to see some interesting sights.

A few km south of Wagga is “The Rock”, rising out of the landscape, with the train line running along the plain below. We passed its striking profile as we headed to and from Wagga. I must get back there some day […]

Cool toys

One of the highlights of the Mega Event weekend was to visit the Wagga Wagga model railway in the botanical gardens. There was a range of engines, and carriages you could sit on for a ride around the extensive set of tracks, bridges, and tunnels. At $2 a ride this was great value. I confess to […]

Mega Event

Australia’s first ever geocaching Mega event (a gathering of more than 500 geocachers) was held over the Easter break. Thus it was that 700 or so cachers (folks who use million-dollar satellites to find plastic lunchboxes in the bush!) descended on the NSW country city of Wagga Wagga for four days of camping and treasure-hunting. My […]
