Однажды китайский ученый Ли Хунь Янь обнаружил некоторую незначительную, однако, существенно отличающуюся от фона корреляцию между количеством псилоцибина потребляемого корфуцианскими медузами и характером передвижения оных по стенкам четырехсотлитровго шарообразного аквариума, установленного в лаборатории по случаю празднования сто второго полугодичного затмения от начала новой эры Сингулярного Прорыва. Недолго думая, Ли Хунь Янь приделал к щупальцам медуз источники излучения в видимом диапазоне но с разной длинной волны, заснял весь процесс шестью камерами с 48 часовой выдержкой, симметрично расставив последние вокруг сосуда, где резвились подопытные и через неделю собрал прелюбопытнейший материал, который, в свою очередь, лег в основу фундаментального труда, ныне известного, как теория полутретичных n-многообразий простой метрики Ли Хунь Янь, с которой (с некоторыми упрощениями и оговорками) я, по мере сил, постараюсь познакомить любопытного и пытливого читателя.
