Guest Posted March 29, 2022 Share Posted March 29, 2022 Turned up to play squash tonight and apparently an error in the app meant they’d double booked the court but hadn’t told us prior to getting there, then for some unknown reason the other people booked on the slot were the ones chosen to get to use it.Take it as a compliment maybe the workers thought the other pair looked like they needed the exercise more. 0 Quote Link to comment Share on other sites More sharing options...

He still loved going to pubs and on quite a few occasions before I could get the carriage off him he would batter into chairs and tables sending everything flying - quite often down me also. I reeked of beer for about a year as a result and miss not being able to call on that as an excuse these days ha What an adorable wee fella. Aye mine has visual difficulties so could never be mad at him. 1 Quote Link to comment Share on other sites More sharing options...

Should've all gone in together, that would have been a right squash. 0 Quote Link to comment Share on other sites More sharing options...

Hex is used in computing as I had to learn it once when doing a computer course. I can't remember why but those of you who remember the early days of Acorns, Spectrums etc will remember memory going up in multiples of 16: 16k, 32k, 64k, 128k etc. There are, of course, only 10 types people in the world: those who understand binary and those who don't. 5 Quote Link to comment Share on other sites More sharing options...
scottsdad Posted March 30, 2022 Share Posted March 30, 2022 On hexadecimal the way to think of it is this. We use decimal (base 10). This means we have 10 characters to represent numbers (0,1,2,3,4,5,6,7,8,9). When you reach a number past nine you then go in to two digits (tens and units). Then three digits (hundreds, tens and units). Binary is base 2. It has 2 characters to represent numbers (0,1). When you get a number higher than 1 you get two digits (twos and units). So the number two is represented as 10. Then three units (fours, twos and units). Hexadecimal is base 16. It has 16 characters to represent numbers (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F). When you reach a number past fifteen (F) then you get two digits (sixteens and units). So the number sixteen is represented as 10. You can apply this to any number really, so long as you have enough characters to represent the individual numbers. 0 Quote Link to comment Share on other sites More sharing options...

I often have that initial reaction to people on mobility scooters before reminding myself that it's very possible for their obesity to be a consequence of a disability. It might not be, but even still pity seems more appropriate than scorn. 1 Quote Link to comment Share on other sites More sharing options...
Stellaboz Posted March 30, 2022 Share Posted March 30, 2022 Nah. Most people are fat, disability or not, because they simply eat far more than they burn off. -1 Quote Link to comment Share on other sites More sharing options...

We all understand the decimal system just fine and anyone who doesn't is hardly likely to understand something even more complex. Alternatively, we should move over to the Chinese system where every number has its own unique character. 0 Quote Link to comment Share on other sites More sharing options...

I did this stuff when doing computer studies at school, so I guess there are folk out there who use it for some reason or another. And as I said earlier, it came up in the Star Trek 25th Anniversary computer game. I remember doing factorising equations at school and one of my classmates doing his nut in asking why we were learning it as nobody would ever use it in real life. I have been using them for 20 years. 0 Quote Link to comment Share on other sites More sharing options...

Isn't there something to be said for the argument that such complex Maths has no place in basic education and should be reserved purely for those who have a specific interest in it? Arithmetic has a real-life application but (much) less so Maths beyond the very basic stuff. 0 Quote Link to comment Share on other sites More sharing options...

Humans don't work on binary so well, but binary doesn't convert well to decimal. Starting a new "level" in hexadecimal coincides with a place value in binary. 0F to 10 is 1111 to 10000, 1F to 20 is 11111 to 100000. I guess it's harder to make typos and easier to spot them if you're typing something more easy to read than a jumble of 1s and zeros. I'd be in favour of reinstating the old babylonian base 64 numbers. Far more elegant symmetry than our ape digit based system. 1 Quote Link to comment Share on other sites More sharing options...

It's much easier if you learn the basics at school than starting from scratch if you need to use triangulation for a diy project or work later on, for example. 0 Quote Link to comment Share on other sites More sharing options...

Agreed - that's why I said include the basics. That said, I think it's exaggerated how useful such stuff is in later life - I can only recall it being useful once when I was fitting some moulding and needed to work out an angle. And, it was so long ago that I had studied it there was no way I was remembering so a call to the old man was required. 0 Quote Link to comment Share on other sites More sharing options...

I couldn't get past needing to know why and how mathematical things work instead of just following the procedure to find the answer. Approaching infinity my arse, what's all that about?!? 1 Quote Link to comment Share on other sites More sharing options...
coprolite Posted March 30, 2022 Share Posted March 30, 2022 Our maths teaching in the UK is well behind other countries. I think Indian schools teach trigonometry to ten year olds. I went to the first lecture for an advanced econometrics module at university. Me and my (Scottish) friend were lost after about three minutes and sat there looking perplexed while a load of greek and chinese students nodded along and followed proper mad scientist type equations and asked intelligent questions. I think only one brit stayed in that class. 0 Quote Link to comment Share on other sites More sharing options...
