BODMAS wasn't a thing when I was at school either, but it very much was when I started teaching (I in fact learnt about BEDMAS from one of my Year 7 students) - I'm not sure exactly when it was introduced into textbooks (it's certainly in them now)

@steter
At Uni we had an open book exam for one of the subjects (I don't remember now what it was - it was either Physics or a Computer Science topic). So, since I would have the book with me, I didn't do any study for that test, just the other ones with no open book. Well, it's a big book and the test didn't go well, because it took so much time looking things up!

@aral
When I first teach students how to make a link in HTML, I Rick-roll them with the link I demo (which I don't tell them what the link is when I paste it in). I mention that for no reason ;-)

And then another one for when you discover a typo after you sent the message 🙂

I was reminded this week about the #algebraic #Mathematics #proof of #Pythagoras theorem, which I always thought was pretty cool, so I thought I'd share it this week for those who haven't seen it. I'd seen the one where you cut out shapes, but I always found that one a little boring, but being a numbers person I really liked this proof, when I finally saw it!

You'll see in the image we have a big square which is made up of 4 triangles and a smaller square...

I've seen this video a couple of times, but I never saw any explanation.... so I decided to work it out for myself how they did that! 🙂 Feel free to watch it and see if you can work it out yourself, but if you can't (or don't want to), then here's how this works (scroll down for reveal)...

First some pronumerals, then the steps - a=97, b=94, c=3, d=6
- c=100-a
- d=100-b
- the first 2 digits is a-d
- the last 2 digits is cxd

Yeah, they start hallucinating, that kinda stuff.

@morph @evan
Not sure if you already knew or not, but the military already did that experiment. It didn't go well for the participants.

@BeAware @phocks
There's an option to exclude boosts from accounts - maybe you have that on accidentally and only see their posts?

It was recently announced that #Mastodon (the #fediverse?) now has (limited) ability to reply to #Threads posts (only tagged people can see it there, and you can only tag one person there) and I got a post today from one of the few people I follow there (in fact boosted by someone else I follow there), so hey, let's give it a shot and reply... and not long after they liked my post! Pretty cool to get my first like from another platform! 🙂 #Federation FTW!

@ricmac
I'm not a webdev, but yep, absolutely. The only time I post there is about the Fediverse, and I have my Mastodon handle in my Twitter handle

@phocks @voxpelli
And there's the catch - to escape capitalism you first need enough money to do so. i.e. you're trapped by the system. When people complain about capitalism, and the sea lions jump in to say "yet you willingly participate in it", that's like saying prisoners willingly participate in prison routine.

Sneak peek of a graphic I made for a talk I'm giving next week about the #Fediverse - choose your po... I mean UI for today's Fedi-mission 🙂

Is "far left" the new "Socialist"? 😂

@inthehands
So does this explain the failure of that NASA mission where one team was using Imperial and the rest were using Metric? 😂

@feditips @Joe_Hill
Ok, but does clicking on a public post open up all the unlisted posts too? That's what I'm not clear about. I'm not sure exactly how unlisted works.

@feditips
So, if you set the subsequent posts to unlisted, and someone from the public clicks on the first post, they will see the whole thread?

Also, I type it up in Mastodon until I near the limit, then copy to Notepad, then ditto for 2nd post, etc., then when I'm at the end I can add the right numbering (e.g. 1/9), and copy them from Notepad back to Mastodon and post them. This also helps with getting the right char count for each, cos of things like URLs only counting for 23 chars, etc.

@feditips @william_1844
So for example, first screenshot is what I see boosted to my Mastodon feed from following a Kbin magazine, and in the post if I click on the link it takes me to the original post (but separate login needed, but pixelfed supports using your Mastodon account, once you have gone through the set-up for that).
