Those eureka moments

The original Apple Computer logo
Historians of science tend to downplay 'eureka moments' when a scientist suddenly has a great idea. 'Constructed after the fact,' they mumble into their beards. 'Real science isn't like that. It's a slow grind, a team effort. Fake memories. Blah, blah...' Arguably this says more about historians of science, and their lack of imagination, than real scientists. For while all eureka moments are certainly not true, I think many are.

To dismiss a couple of unlikely ones, I very much doubt that the original Archimedes jumping out of the bath story has any validity. And there's good evidence that Galileo didn't get a sudden understanding of gravitational pull while dropping balls of different weights off the leaning tower of Pisa. (The evidence for this is that Galileo never mentions it. It is only told by an assistant who was writing about Galileo near the great man's death. But Galileo was a superb self-publicist. If he had done it, he would have bragged about it.)

However I'd also like put forward a classic that I feel probably is true. Newton and the apple. I'm not saying that an apple hit him on the head - that is pure fiction - but I don't think it's at all unreasonable that seeing an apple fall sparked a chain of thought. Here's Newton's own words on the subject, related by the historian William Stukeley:
After dinner, the weather being warm, we went into the garden, and drank thea [sic] under the shade of some apple trees; only he and myself. Amidst other discourse, he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. Why should that apple always descend perpendicularly to the ground, thought he to himself; occasion’d by the fall of an apple, as he sat in a contemplative mood.
The fact is that there is strong evidence that humans tend to come up with their best ideas when they are not sitting at their desk trying to work, but rather when they are only half conscious of what they are dealing with. Perhaps on a walk (I get most of my ideas walking the dog), driving, or in Newton's case, sitting relaxing. It feels right.  So hands off, historians of science. Even if it wasn't true, this kind of story is useful as myth - but in this case there is every possibility that it was.

  1. Possibly Newton's words about how the notion of gravitation came to him were somewhat disingenuous. After all, Robert Hooke had been making somewhat similar points some twenty years earlier. And Newton himself acknowledged the earlier work of Bullialdus and Borelli.

    Newton and the apples is a nice story. He wasn't a bad self-publicist either, it would seem.

  2. Watch this space for a post on Hooke, coincidentally, on Friday. Hooke had made some observations that were new to Newton (one of which Newton acknowledged getting from him), but didn't come close to the full works.

    I'm not suggesting anyone isn't influenced by others - shoulders of giants and all that - but that the apple event probably did happen as a point where it all came together.

    Newton wasn't a great self-publicist, he was rubbish at publishing. It was usually someone else who pushed it through or publicized it, in this case Stukeley.

Why I hate opera

If I'm honest, the title of this post is an exaggeration to make a point. I don't really hate opera. There are a couple of operas - notably Monteverdi's Incoranazione di Poppea and Purcell's Dido & Aeneas - that I quite like. But what I do find truly sickening is the reverence with which opera is treated, as if it were some particularly great art form. Nowhere was this more obvious than in ITV's 2010 gut-wrenchingly awful series Pop Star to Opera Star , where the likes of Alan Tichmarsh treated the real opera singers as if they were fragile pieces on Antiques Roadshow, and the music as if it were a gift of the gods. In my opinion - and I know not everyone agrees - opera is: Mediocre music Melodramatic plots Amateurishly hammy acting A forced and unpleasant singing style Ridiculously over-supported by public funds I won't even bother to go into any detail on the plots and the acting - this is just self-evident. But the other aspects need some exp...

Murder by Candlelight - Ed. Cecily Gayford ***

Nothing seems to suit Christmas reading better than either ghost stories or Christmas-set novels. For some this means a fluffy romance in the snow, but for those of us with darker preferences, it's hard to beat a good Christmas murder. An annual event for me over the last few years has been getting the excellent series of classic murderous Christmas short stories pulled together by Cecily Gayford, starting with the 2016 Murder under the Christmas Tree . This featured seasonal output from the likes of Margery Allingham, Arthur Conan Doyle, Ellis Peters and Dorothy L. Sayers, laced with a few more modern authors such as Ian Rankin and Val McDermid, in some shiny Christmassy twisty tales. I actually thought while purchasing this year's addition 'Surely she is going to run out of classic stories soon' - and sadly, to a degree, Gayford has. The first half of Murder by Candlelight is up to the usual standard with some good seasonal tales from the likes of Catherine Aird, Car...

Is 5x3 the same as 3x5?

The Internet has gone mildly bonkers over a child in America who was marked down in a test because when asked to work out 5x3 by repeated addition he/she used 5+5+5 instead of 3+3+3+3+3. Those who support the teacher say that 5x3 means 'five lots of 3' where the complainants say that 'times' is commutative (reversible) so the distinction is meaningless as 5x3 and 3x5 are indistinguishable. It's certainly true that not all mathematical operations are commutative. I think we are all comfortable that 5-3 is not the same as 3-5.  However. This not true of multiplication (of numbers). And so if there is to be any distinction, it has to be in the use of English to interpret the 'x' sign. Unfortunately, even here there is no logical way of coming up with a definitive answer. I suspect most primary school teachers would expands 'times' as 'lots of' as mentioned above. So we get 5 x 3 as '5 lots of 3'. Unfortunately that only wor...
