Early morning, with my cousin in tow, I collected a couple of friends, and set across the bridge in the Morris Minor.
But how to get to the top of the arch? There to cavort
and take in the view.
As to getting onto the arch: the direct route was blocked by a locked gate, about which was erected a barrier in the shape of a rising sun -- the Department of Main roads seemed to think every day was Anzac Day.
But then it was really easy.
From the arch we watched ships passing underneath
and clambered over both arches and the painting cranes.
On the very top of the arch, there is a tower to climb.
Stepping from the arch onto the painters travelling plank, it paid to look at the camera rather than at the gap below one's feet.
In the background are the wharves to the west of the Harbour Bridge.
And after all that clambering about, time to dive in for a swim near Luna Park.
or maybe a ferry ride to Manly.
But what's that east of the ferry -- its Benelong Point -- but no sails.
Benelong Point had for many years been the locale of a key city tram depot -- which was demolished to start construction of the Opera House. The last tram actually ran during 1961. The Opera House was finally completed in 1973.
This arch trip was the only such trip I lead in daylight -- all other arch trips were done at night. It was just a private trip. But later on in the same year I organised an evening arch tour for all the interested delegates to a university student conference -- that of the National Science Faculty Association, Undoubtedly the first organised arch tour.
DISCLAIMER: Since this era security cameras have been installed everywhere on the bridge. And Police comms are much improved. So don't even think of copying this action. Just pay your $$$ to the tourist operator.
are captivating problems in qualitative physics, which require at most high school
mathematics for their solution , and mostly no maths. YoYo -- to left -- is an example dragon. Note conflicting heuristics.
Upper case = YOYO for a steady pull to the right- which direction does the YoYo go? YoYo rotates clockwise ??
Lower case = yoyo for a steady pull to the right- which direction does the YoYo go? In direction of pull?
The paper I wrote at MIT in 1974, Artificial Intelligence Lab memo 338 (1974) elucidates the Art of Snaring Dragons, and relates dragons in qualitative physics to the conservation puzzles such as the egg cup puzzle, and other qualitative puzzles Piaget used to explore the thinking of children.
