Parallax and gardening

The plan for today was to write a new proof for 100 Proofs that the Earth is a Globe. I managed to get one completed: 45: Parallax of the Moon. This proof includes a practical experiment that I can do, with the help of readers in different places around the world. So if you’d like to help, please give it a look!

After finishing that, I walked up to the hardware store to get some hex keys. I have a hand towel holder in the bathroom that’s been loose for ages. It’s held onto a wall bracket by a grub screw with a hex key head. In the past few days I searched for the original hex key, but couldn’t find it in the likely places, such as either the mini toolbox under the kitchen sink, or the big toolbox in the garage. So I had to go buy some hex keys. Measuring the size of the needed hex key was pretty much impossible, so I figured I’d just buy a set with various sizes.

Of course I got to the hardware stores and they have sets in both metric and imperial sizes, and of course I have no idea which one I need, so I end up having to buy both. Fortunately it was only $5 for a set of 8 keys in each type, so I paid $10 for 16 keys. I got home and picked a likely looking size – 2.5 mm from the metric set – and it fit perfectly. I tightened the grub screw… but the towel holder was still wobbly. So I unscrewed it completely and took it off the bracket, and discovered that the bracket itself was loose on the wall. So I got a screwdriver and tightened that up, then reattached the hook and tightened up the grub screw, et voilĂ ! The hook is now firmly attached and not wobbly any more.

And I have 16 new hex keys, 15 of which I’ll probably never use. And one of which I might never use again.

This afternoon I went out to the park across the street to use my new weeding tool (bought the other day) to remove some bindii from the grass. I’ve never done weeding in a garden/lawn before, but it was pretty easy to figure it out. I used gardening gloves, but even so, the thorns from the bindii sometimes poked through the gloves and into my fingers. It was some work squatting on the grass and pulling weeds, but I collected half a bucket full in about an hour, clearing an area of a few square metres of bindii. This will make it much more comfortable for Scully to walk around, although I’ll need to clear quite a bit more space to get the little park fully clear.

Tonight is our fortnightly games night, still virtual because of COVID. I’ve managed to win a game of 7 Wonders and 6 Nimmt so far.
