You can use Unicode characters in #Python identifiers if they are classified as letter-like, but that doesn't mean that you should!

You think you know English pretty well... then you try to describe your cat and you have to talk about their... face. But cats are animals, animals in your language don't have a "face" they have...er... a "muso", that's what you learned as a child right? Humans have a "face", animals have a "muso". Except you can't find a word to translate it because is neither "snout" nor "muzzle". It is the face of the cat ... but you can't bring yourself to actually write "face"...😑

Yesterday I showed you a bunch of cute pictures of tuning systems, like this one.

On the outside you see a 'circle of fifths' with numbers saying how sharp or flat each fifth is. Bigger positive numbers mean more sharp, and I make them brighter green. Bigger negative numbers mean more flat, and I make them brighter red.

Inside there's a 'star of thirds' saying how sharp or flat each major third is. The same rules apply.

Basically, bright colors sound bad. Black is best. You'd like all the numbers to be zero and all the arrows to be black. But that's impossible! It's like lumps in a carpet that's too big for your floor: if you make parts of it nice, other parts get lumpy.

So what's allowed?

Some people claim that our current tuning system, where the note A is 440 Hz (cycles per second), is bad for your health. They prefer A=432 Hz. But more interesting to me is that the A=440 standard arose because 439 is a prime number!

In early Europe tuning wasn't standardized, and the pitch of organs ranged from at least A=337 to A=567. As musicians started traveling more, the desire for standardization increased. Handel expressed a fondness for A=423, Mozart for A=422. Later there was a kind of arms race toward higher and higher pitches, going up to A=450.

This became tough on singer's voices - so in 1859, the French made A=435 the law in that country. At the urging of some opera singers, this standard was adopted for a while in other parts of Europe.

In 1896, London’s Royal Philharmonic Society got around the A=435 rule in a funny way. They argued that when the French set the A=435 standard, they had not specified a frequency, but had specified 59° F as the room temperature under which a particular oboe played A at 435 cycles per second. They argued that the same instrument at normal room temperature would play an A at about 439 Hz. So they took that as the standard!

Later, in 1939, the BBC wanted to play a standard tuning note before broadcasting concerts. Their note was derived from an oscillator controlled by a piezoelectric crystal that vibrated with a frequency of one million hertz. This was reduced to a frequency of 1,000 hertz by electronic dividers. Then the frequency was multiplied by 11 and divided by 25 giving a frequency of 440 Hz. Since 439 is prime, it was inconvenient to create a frequency of 439 Hz this way.

#TIL It is straightforward to sort strings in natural order in #Python (that is, with numbers in numeric instead of lexicographic order). This is explained by @nedbat here:

The standard metric on the sphere in polar coordinates is:

dθ^2 + sin^2(θ) dφ^2

But what if we change this to:

(1 + h(cos(θ))^2 dθ^2 + sin^2(θ) dφ^2

for some function h(x) from [-1,1] that satisfies:

h(-x) = -h(x)
|h(x)| < 1
h(1)=0

It might seem that we’ve just distorted the sphere arbitrarily, but requiring h to be an odd function means several global quantities remain unchanged.

Along geodesics of the new surface, we have:

dφ/dθ = sin θ_0 (1 + h(cos θ)) / (sin θ √[sin^2(θ) - sin^2(θ_0)])

where the geodesic is tangent to circles of latitude at θ_0 and π-θ_0. But if we integrate this between those endpoints, because h is odd we always get:

Δφ = π

So, the longitude of every geodesic changes by π as it moves between its two extremes of latitude.

Similarly, for the distance s along a geodesic:

ds/dθ = sin θ (1 + h(cos θ)) / √[sin^2(θ) - sin^2(θ_0)]

with an integral between the same circles of latitude:

Δs = π

Joining this curve to its mirror image always gives a closed curve of length 2π.

We also get an unchanged total surface area of 4π.

Reference: “Manifolds all of whose geodesics are closed” by A L Besse, Ch 4. H/T @RobJLow

A sphere deforms, while a set of geodesics on it continue to be closed loops

I'm very excited about #Canopée's hard sails. The vessel will be transporting #Ariane6 to the Kourou launchpad.

The semi-rigid hard sails are expected to provide a 30%-50% fuel reduction depending on the wind direction. This has huge potential to reduce emissions of maritime transport.

Engine powered off, the ship sailed at 9.4 knots at a 50° wind bearing with a 19 knots wind, which is quite impressive.
