EVs: Blowin' in the wind

All UK sales of petrol and diesel powered vehicles are to end by 2030. Electric (EV) and dual fuel types made up 23 per cent of new purchases last year, but progress may slow down as the promotion approaches the less eco-minded end of the market.

EVs have advantages - helping cleaner air in towns, cheaper energy costs per mile (at point of use.) Their maximum range is improving, too. And it’s such fun quietly creeping up on people at pedestrian crossings or in supermarket car parks!

Nevertheless, try as they may, the drivers cannot entirely ignore the fact that most of the electricity originates from burning coal, gas or imported woodchip - hardly ‘green’ ! As for nukes, ‘Atomkraft? Nein danke!’ (we’ll see quite enough of that in Ukraine if the madness escalates.)

How about renewables? The contribution from them is relatively small, and has its own problems. Tidal energy projects threaten the ecology of shores and wetlands. Sun- and wind-power are unreliable.

What you need is something that works all year round, and most importantly maintains the illusion of ‘saving the planet’ - perception is all.

We have a modest proposal…

What our windmills need is a constant, steady blast of air. So let’s not rely on fickle Nature: let’s provide it ourselves; or rather, arrange for Ireland to provide it. We have in mind a vast range of gigantic fans stretching from Dundalk to Wexford, blowing a ‘fine gale’ across the Irish Sea towards serried ranks of windmills stationed between Blackpool and Cardigan Bay.

The construction on both sides will create much-needed employment for both countries, and foster goodwill in Dublin that may also help smooth over the EU’s obstacles to cross-border trade with Northern Ireland. Meanwhile Westminster can tell Britain’s motorists that their vehicles are being charged ‘sustainably’ (within our borders, which is what matters) and that our nation is advancing rapidly towards Net Zero.

How will the Irish fans be energized? By the usual combination of imported fossil fuels, of course (and surely HMG can come up with a scheme for financial reimbursement.) If the model is of the Dyson bladeless type (scaled up hugely), no birds will be chopped and thanks to the air purifier design, atmospheric pollution particles will be (re)absorbed.

Alternatively, Ireland could build a host of nuclear power stations. It would be their turn to dump radioactive waste into what, to make them feel even better about it, we might agree to rename the English Sea.

Either way, no EDF for the building work please, what with their delays and cost overruns. Bring in the Chinese, who know how to get things done. You can’t have too much international goodwill; nor self-delusion, come to that.

FRIDAY MUSIC: Billy Preston, by JD

Billy Preston (September 2, 1946 – June 6, 2006)

More good music, just for us oldies...... from Billy Preston who was something of a child prodigy appearing on TV at the age of ten alongside Nat 'King' Cole as can be seen in one of these videos below.

"Billy Preston is arguably one of the finest session keyboardists the sixties ever saw. His work with The Beatles is renowned but he also worked with some of the finest artists of the decade including the likes of Sam Cooke, Little Richard, the Everly Brothers and Ray Charles. It was a performance with the latter is where Harrison would rekindle their friendship and, for a time at least, induct him as the fifth member of The Beatles."

“It’s interesting to see how nicely people behave when you bring a guest in, because they don’t want everybody to know they’re so bitchy,” Harrison remarks in Anthology. “Suddenly everybody’s on their best behaviour.”

“He got on the electric piano, and straight away there was 100 per cent improvement in the vibe in the room,” wrote the guitarist. It was clear that the atmosphere had changed for the better. “Having this fifth person was just enough to cut the ice that we’d created among ourselves.

FRIDAY MUSIC: Beethoven, by JD

 After Chopin it is only right that we should have some piano music by Beethoven and why not!

"Like much of Beethoven's work, his piano music can vary depending on when it was composed, what he was thinking about and, crucially, how grumpy he was. There's a fantastic range of moods to explore, from the light and humorous stuff to the dark and stormy struggles of a tormented soul… so brace yourself and get ready to experience Beethoven, the pianist."

Math: Learning in US is undermined by flawed testing, by Paddington

If I were to single out one thing which holds much of US education back from excellence, it is the structure of tests.

So much of the testing used is multiple-choice, fill in the bubble style, which prevents students from being tested on developments in the Mathematical areas, and from expounding on ideas otherwise.

I think back to the tests that I took in French and German at O-level (age 16), which required translation in both directions, making up a story in the foreign language, reading a passage in the language and answering questions in English, taking dictation, and having a conversation. The English language test was similar, with the translation replaced by having to precis (summarize) a long passage in 150 words or fewer. This latter was a very valuable skill, and one which many people would benefit by learning.

Our Science and Mathematics tests required solving long problems, writing essay descriptions of experiments, and developing theories.

How could multiple-choice tests possibly be that challenging?

To be fair, or possibly reasonable, the tests were set up so that 35% or so was a pass/C and 70% was an A.

And then, when all is said and done, we have students who have had their parents/software/tutors do most of their work throughout high school (and sometimes college as well), yet cannot pass tests. Those students are then claimed to 'not test well', and are given special accommodations. We had cases of assistants provided by of Office of Accessibility simply reading the answers to students, line by line, during tests. When the latter happens, what is the point of testing or grades at all? When those enabled students finally hit a brick wall, the claim is that “tests don't check for learning”, when they most certainly can and do.

FRIDAY MUSIC: Tiny Tim, by JD

Can you remember this very unusual and unique musical talent from the Sixties? The one and only, never to be forgotten, Tiny Tim!

Among his many fans were The Beatles, Bob Dylan with The Band and Jim Morrison of The Doors as can be seen in three of the following videos.

Tiny Tim was born Herbert Buckingham Khaury on April 12, 1932, in New York, New York. His father, Butros Hanna Khaury, was from Lebanon and his mother, Tillie Staff, was a Jewish woman from Poland. Tim was raised in the Washington Heights section of New York City, where he developed a love for American songs and music, mostly from the late 1800s through the early 1900s. An unhappy student, Tim dropped out of high school and learned how to play the guitar and the ukulele.

"I first saw Tiny Tim very early in his career, in Greenwich Village in the winter of 1962–63. There was a convention of college newspaper editors, and a few of us – I remember Jeff Greenfield coming along – went to the Black Pussycat and found ourselves being entertained by a man the likes of whom we'd not seen before. He was already locally popular."

Math: train hard, fight easy, by Paddington

Before implementing solutions to a problem, it is wise to understand what the issues are.

In 1957, our government and business leaders began to recognize that high-level Science and Technology were essential to our economy and national security, requiring a large number of people trained in Mathematics, the language of Science. It also became apparent, and more so over the next 60 years, that the performance of US students in the subject averaged mediocre at best, when compared with other industrialized nations.

The conclusion that the experts came to was that there was too much rote memorization in US education, and not enough understanding. Interestingly, the many groups of Mathematics education reformers rarely include actual mathematicians. When they do, it is most often ones whose work does not require the use of tools such as the Calculus and Trigonometry.

The implemented solution was the 'New Math', and was a disaster, in large part because the teachers didn't understand what they were doing.

Later, when the situation stubbornly refused to improve, the new reformers introduced ideas such as 'lean and lively' Calculus (i.e. teach less) and taught students to use calculators and computer systems to do the rote calculations.

The end result has been that the percentage of students who have learnt the bare required facts and can do the basic computations has shrunk. Of the remainder, many have decayed their skills so far that they cannot correctly input expressions to their computing devices, and cannot understand the resulting outputs. God forbid if you ask them to do anything with fractions or percentages.

The underlying problem was that the 'expert' reformers did not understand that Mathematics is both a language and a mode of thinking. Except for the savants, its learning requires repetition of operations, by hand. After all, we don't expect people to learn instruments by listening to music, do we?

In years past, I had classes prepare a study sheet for first semester Calculus. Most could fit every definition, theorem and rule required on less than one sheet of paper. For how many subjects could one say that?

However, when I awarded 20% of the grade on the final (announced beforehand) to reproduce 3-4 of the definitions and statements of theorems, no more than 1 in 20 of the students could get them correct.

So much for 'rote learning'.

FRIDAY MUSIC: Christmas music (part 2), by JD

Part Two moves eastwards and further away from the 'traditional' carols and closer to the reason for this celebration. 

The fourth video may not be strictly correct (Christmas Eve would normally be compline and not vespers) but the lead singer here has a fabulous voice.

Merry Christmas!
