Thread: We have been Tealed..!

When I was teaching (only a few years ago), I used to say, "I'll believe you (students) are serious about the environment when you don't throw your litter around the school yard". I even went to the trouble to collect food scraps thrown on the ground and piled them in the quadrangle next to the flagpole. My words and actions were never popular among the students because they struck a nerve. It's always someone else's fault. Blame the Government.

I used to drive past a very expensive private school in Hornsby, you know it was expensive because they had copper gutters put in for their extension, but anyway.. the street outside was parked with Cars, with Red P's on them. Always amused me the commitment to environment..

When my young bloke was living at home, his existence was characterised by waste, long showers, lights and appliances left on in every room, etc. Now he has his own place he has become Mr Scrooge. Minimum number of lights on, has timers on some appliances so they can only get accidentally switched on during the day and use solar and minimises the number of car trips he makes. He even gets his old man to take his recycling materials to the recycling centre. I have a van and when I go around to see them he piles all the recycling materials into it and as I go past the centre I can stop off on the way home and drop them off.

Our youngest daughter (32 years) still lives with us with no sign of her wanting to move out. She has a fairly stressful job in IT. She regards the half hour drive home as "therapeutic". she keeps her to her self for the most part.

Last week end I made a comment on our measuring in metric now (only for the last 50 years). She said that Australia had to decimlise because Imperial measurements were not accurate???? I didn't have the energy to try to make her think any different. I almost said that 000's are pretty accurate but I declined

Most people's understanding of accuracy and precision are usually inaccurate and imprecise.

I picked this up when it was released in 2019, extremely good book and shows what we have been doing to get evermore exact with measurements.

My daughter speaks several languages. When I give here an imperial measurement she says, Whats that."

Great book - my copy has been read by about 10 people. 3 of my bro/BILs are engineers and they all read it and we've have in depth discussions about it at family gatherings. The rest of the family get these puzzled looks on their faces until one of them says - oh they're discussing that book AGAIN.

I don't think you can be more exact; something is either exact (ie an integer) or not. You may, however, be more precise or more accurate.

I agree, it's an excellent book. As a result of his reading it, the chairman of our woodworking association asked several of us to talk on measurement, accuracy and precision. One of the other speakers brought along a set of Jo blocks, something I had never seen before, although I'd heard of them.

I prefer the metric system, it's a dozen times easier.

My 17yo has been hanging around in my workshop too long. She understands feet and inches quite well. Metric is too confusing as she speaks in centimetres and I speak in millimetres (proper engineering speak).

Cheers, Vann.

I think centimetres are a preserve of the "ragtrade."

My mix bottle for the chainsaw is typical European - Centilitres.
And all guillotines in the print trade from Europe were in cm and they used the comma instead of the point as decimal place so 297mm became 29,7cm. Confusing until you get used to it.

Correct.

There have been number of confusions between myself a SWMBO over this. Last year she wanted these special 200x400 mm isosceles triangular rulers made out of acrylic with measurement marks on them - luckily she only wanted cm markings.

Due to my health status and the covid situation here in WA I am not going in to any shops. SWMBO has Vertigo so she cannot drive. So I either buy stuff on line or drive her to the shops and she masks up and goes in to buy groceries or what I'm chasing from assorted hardware/electronics stores etc. SWMBO fully supports this as she says I'm too forgetful and would forget to wear a mask or sanitise etc. While she's in the shop, if its going to take a while I sometimes take the dogs for a walk.

A few months back I sent her into a hardware store for some M8 x 50 bolts - being a quilter she assumed I meant M8 x 50 cm so she called me to say they didn't have any.

Now if I can find said item(s) on a website showing specs and picture I print off a copy and send her into the store with the printout and just tell her how many.
She's picked things up fairly quickly and now knows where all the various fasteners are located in Bunnings.
If I cannot find a picture for her to bring into the store I send her in with a written description and once she thinks she's found it in the she sends me a photo to confirms she got it right.
