EV road tax

Yeah right. Explain why there are 20cwt/ton, 8 stones /cwt, 14 lb/stone and 16 oz/pound. I can do fractions but metric is no problem. Fractions are easy in simple maths (the questions at GCSE most often cancel to leave an easy final calculation) but you do need top heavy fractions for that. Those who rely on calculators prefer decimal to base ten - fractional conversion calculators have likely mostly disappeared these days.

Back to slide rules?

GCSEs they weren't around when I was at school, besides anything else, didn't they bring GCSEs in just for people who couldn't pass O'levels ......

When I was at school in the 70's we had O levels in grammar schools and CSE's in secondary schools, in fact our year trialed one of the upcoming GCSE exams so I ended up getting English language in both O level and GCSE

Fractions work for any measuring system, half a mm, half an hour or half a light year.
But
If you try to explain fractions to a calculator kid, I think it actually frightens them.

I hope so that's around half what I pay now.

So that's about .5 of what you pay?

I must be remembering it incorrectly then? I was under the impression that we had CSE as the lowest grade, GCSE as the norm, AKA (O)rdinary level and then (A)dvanced level.

Time is yet another problem area.

The utter joy....there's 365.25 days in the average year...giving 52.18 weeks in the average year. Unless we're doing it proper...then we need to know which year is a leap year!

Then there's the days in the month of course!

I'm surprised someone hasn't decided this all needs some updating.

Good luck getting the moon and earth to comply with your new system

The O level was a GCE (general certificate of education) which along with the CSE was replaced with the GCSE

Problem is the elliptical orbit of the moon.."just" fix that and we are all good

You can express 1/3 precisely fractionally but not decimally. 0.33333333333333333333333333333333333333333333333333333333333

And 1/3 is easy to visualise too.

BTW> I am not anti-electric vehicles...I just think that whole rush into it was a knee-jerk reaction to Global warming, which just wasn't thought through.
As many have pointed out, the pollution created by manufacturing and generating power for EVs, negates the positives.
The only real way forward to reduce CO² emmissions is to wean people out of personal transport on on to public. Logically there is no other way with present technology. Obviously when we all have hover-shoes and have lost the ability to walk unaided, which I'm fast approaching, then we will be saved from imminent destruction.

The problems there are convenience and more importantly, the fact that someone else can stop you travelling at the "flick of a switch".

Apparently 40% of people who took o levels in 60s and 70s would pass.

What is V2G? What does it mean that electric cars can balance the grid? Vehicle-to-grid technology has the power to transform the whole energy system. Here’s how.

I will just leave that with you lads...

Now your not allowed to fail incase you get offended. I did mine in 78 and did far better than I or the school predicted!

Reached -7 up here last night. Wife charged the Leaf overnight and has driven to Harewood house. No drama, she used heating, heated seats, heated rear windscreen, radio, indicators and other electrical features without issue. Road didn't break up under the pressure of all those electrons either

Having a few cold weather runs now under my belt in my E Berlingo .
A full 174 mile charge in the can appears to use 47 miles of juice powering lights , radio ,blue tooth , heater to 23 oC and numerous screen wash & wipes leaving 19 miles in the can so to speak .
Hassle free charging at home in minus 4 oC , using the latest generation of smart charger that is controlled by" Ohme " computers that use minor increases in the grid to give many many short bursts of charge during the 24 hrs. of charge which at present is only charged to us at low night rate no matter what time of the day or night it is .

It will be interesting to see how it performs if we get down to minus 15 oC .

Metric is base 10 just like money….imperial is as you said fractions and not intuitive. And I can do fractions….I guesstimate in feet and inches, but measure in metric. Though in machining thou works too

Try turning a unit of length into decimals using just a pair of dividers. . Then if you are intelligent you'll realise that 1/2 , 1/4 , 1/8 , 1/16 , 1/32 & 1/ 64 ths are a very clever & accurate way of measuring that has been used for centuries .

 

[DAPPH]

Makes a lot more sense that the base used is the same as the number of fingers we all have!

Metric/decimals just fractions with the denominator limited to multiples of 10.

You been measuring Wisbech style ? Most normal people have eight fingers & two thumbs .

I understand the theory, but a 1/64th of a fathom isnt very clear really
