The Logarithmic Spiral Gears is an extreme example of non-circular gear sets.

It's based on the famous Fibonacci spiral and evokes the cross section of a nautilus shell with internal chambers

@roaldcs El Imperio español conservó la gramática del náhuatl (1547), el quechua (1560), el aymara (1603), el mapuche (1606), el tagalo (1610), el guaraní (1639), el maya (1684) y docenas más.

多くの日本人「モスクは日本に必要ない。祈りたいなら家で祈りなよ」

ムスリム「厳格な時間制限があり、1日5回の祈り (サラート) には、それぞれ決まった時間枠がある」

日本人「・・・」

ムスリム「その時間を過ぎてしまうと義務を果たせなかったことになるため、家に戻るのが間に合わない場合は、その時いる場所（職場、公園、商業施設の空きスペースなど）で祈る必要がある」

日本人「・・・・・」

ムスリム「ついでに言うが、ハラール食と土葬と同姓の医者と改宗をうんたらかんたら」

日本人「うるせーんよ！日本に住んでるなら少しくらい日本に合わせろ！無理なら自国へ帰れ！」

合ってるよね？🙋‍♀️

@PhilosopherWar It is, indeed, an unprecedented phenomenon. More so because conversion to Christianity comes with persecution and death in the countries where it happens.

This kind of complication is counterproductive, because any child smart enough to benefit from it will naturally figure out a system of his own (then be punished for not showing his work) and it makes simple math far more complicated than necessary for the less intelligent.

The wave equation in spherical coords:
∇²Φ = (1/c²)∂²Φ/∂t²
drives these levitated droplets into pure l=3 & l=4 modes.

Watching a water drop morph into perfect triangular stars & quadrupolar symmetry at ultrasonic resonance is pure fluid poetry.

@manarmn__ I’m technically not supposed to have my slides quoted like that, but thanks for sharing them!
Since you’ve gone that far, why not add a concrete calculation example as well?
Apologies that it’s all in Japanese—just let an AI handle the translation and have fun with it.

A cutting reflection from Cardinal Ratzinger, Good Friday 2005:

"Pilate is not utterly evil. He knows that the condemned man is innocent, and he looks for a way to free him. But his heart is divided. And in the end he lets his own position, his own self-interest, prevail over what is right.

Nor are the men who are shouting and demanding the death of Jesus utterly evil. Many of them, on the day of Pentecost, will feel "cut to the heart," when Peter will say to them: "Jesus of Nazareth, a man attested to you by God... you crucified and killed by the hands of those outside the law."

But at that moment they are caught up in the crowd. They are shouting because everyone else is shouting, and they are shouting the same thing that everyone else is shouting. And in this way, justice is trampled underfoot by weakness, cowardice and fear of the diktat of the ruling mindset. The quiet voice of conscience is drowned out by the cries of the crowd.

Evil draws its power from indecision and concern for what other people think."

英国の博物館「日本の侍の半分が女性だった」と主張。

これは英国博物館で2026年2月3日から開催された「Samurai」展でのこと。

「侍」という言葉が一般に連想させるのは甲冑を着た戦士であり、そのイメージはほぼ男性です。人口の半分は女性なので武士階級の半分は「女性」というのは誤りではないが、しかし、この「戦う侍の半分が女性だった」と意図的に誤解を招く表現です。
