up to the mid 1970's high school students in our school were still taught to use the slide rule for mathematical computations. most kids nowadays no longer know what this is
After a long day, including driving from Suva to Nadi and various events in town I realised I hadn't taken any photos. This is a rather strange looking slide that was part of the children's playground in the hotel in Nadi.

I remember sliding down this when I was a kid..many moons ago LOL

This is a photograph of a real slide rule.
Although they look complicated, the principle of operation is simple.
The device is used to add the log (logarithm) of numbers.
Adding (or subtracting) the log of numbers has the same effect as multiplying (or dividing) the numbers. The ability to quickly perform multiplication or division was the key to the usefulness of the slide rule.
The sliding part is used to perform the addition. Move it a certain distance, and all the printed numbers along the length have been moved along that same distance, obviously. Effectively they have all been "added to" by the same amount.
The "conversion" from number to log was done simply by labeling a logarithmic scale with the corresponding number. Consequently the scales look uneven, with numbers "bunched" towards one end.
All the other scales are the equivalent of lookup tables. This set of scales can be used to determine 1/x, x squared, x cubed, log x and basic trigonometry functions such as cos, sine, etc.
Slide rules were almost universally used - from their invention in th 1600s until the 1970s - before pocket calculators became available and affordable. Almost everyone had one. They also needed to be constructed to high standards of accuracy to be useful. This one, although only plastic, clearly has machined/milled sliding surfaces to produce a smooth but snug fit. The combination of high manufacturing costs and a large, predictable, steady market made them not very profitable items to produce.
Blundell Harling - who made this model in Britain - continue to operate, making quality drafting and navigational aids such as chart plotters.
A special type of circular slide rule - the "whiz wheel" flight computer - is still widely used in aviation. Presumably, with potentially many lives at risk, it is reassuring to have a reliable backup device that won't suffer from software crashes or lightening strikes.

For Fourth of July weekend this year, we went up to Westminster, where I grew up, and spent a day with Grandpa Rich and Grandma Janelle. It was lining up to be a hot weekend, and when we arrived, we found grandma and grandpa sitting in the shade of a tree. After some discussion, we thought Paige would enjoy some fun in the water to cool down, so Marna went off to get a slip-n-slide.
While Paige was a little less than eager to throw herself onto a slippery surface, and slide out of control for almost twenty feet, she eventually took to it like all other water activities.
After some grilled burgers and potato salad for dinner, and as the sun started to disappear, we unloaded a bag full of fireworks (legal) that we didn't get to last year. Paige got her first run at sparklers, but enjoyed watching dad and grandpa prance around the backyard more, and handed of the responsibilities. After that we started with some small fountains. As the night progressed, there was a steady mix of both legal and, not-so-legal, fireworks.
After fireworks, Marna and I went to a nearby hotel to spend the evening, and wake up the next day for a little grown-up time. After a leisurely breakfast, we moved on to see Hancock. Although we hadn't heard any amazing reviews, we really enjoyed the comedy and twists of the movie. We then re-connected with Paige and the grandparents at Dairy Queen.
Paige had spent the morning tiring out the grandparents. She spent some more time on the slip-n-slide, then the hot tub, then the slip-n-slide, then ... Afterwards, Paige took her grandparents to the playground. When the heat started to rise, it was off to Dairy Queen for a mint Blizzard. The remainder of the day was spent back at home in Parker, CO playing with Paige's friends Hannah and Logan.
Slides are a big part of his day to day activity. He loves em so much we even bought him his own little house slide.
57 and counting on this day.
He simply just can't get enough of them. I, on the other hand, am glad to see the end of it when those weary little legs kick in.
Seeing that this boy revisits whatever slide he encounters in constant carousel like motion, I decided to keep track of the number of times he took the plummet on this particular shute and I decided to let him go until he had enough.
I couldn't believe how much energy the boy had. Just say one plummet and one point of return takes an average 20 seconds. Going off count 57, he had been sliding, running around the bend, climbing the steps upto the platform, for in excess of 19 minutes.
I had to pull him aside and tell him that his little arse would be burning with friction by now, but of course he wouldn't understand a word of it. So instead I offered him an oreo in the car.
On a sidenote, I must say iPhones (5 and up, not sure about the older models) make great handy action cameras. This shot I held my thumb down on the shutter creating multiple burst shots whilst swiftly and quickly panning the phone in the direction of the downward movement. Creating the diagonal blurry streaks in the background which nicely gives the picture a sense of motion.
