полоски зебры служат не только камуфляжем от хищников, но и для отпугивания кровососущих насекомых


Выяснилось, что полоски зебры служат не только камуфляжем от хищников, но и для отпугивания кровососущих насекомых. Полоски не мешают мухам и слепням находить жертву, тут они справляются, но проблемы возникают при посадке: у насекомого "сбивается" оптика. Муха оценивает скорость, с которой визуальные контуры объекта расширяются в ее поле зрения, и на основе этого автоматически корректирует свою скорость, чтобы вовремя затормозить. Высококонтрастный черно-белый узор ломает эту зрительную систему.

В СССР была самая лучшая медицина? Да, все познаётся в сравнении!


США, 1925 год.

Врач говорит пациенту, что он выглядит изможденным, и выписывает ему тонизирующее средство. Это дистиллированная вода с радием. Продано четыреста тысяч бутылок с медицинской рекламой, а сталелитейный магнат по имени Eben Byers, выпивший полторы тысячи, похоронен в 1932 году в свинцовом гробу. https://en.wikipedia.org/wiki/Eben_Byers

Перед смертью Eben Byers весил около 40 кг. Ему полностью удалили почти всю верхнюю челюсть и часть нижней, а в костях черепа образовались отверстия.

Немного этимологии


Ангел — просто вестник. В «Илиаде» angelos — это обычный человек, приносивший известие.
Энтузиазм — религиозный экстаз. Буквально en — внутри, theos — бог. Шоссе Энтузиастов недоумевает.
«Симпозиум» — совместное распитие спиртных напитков. Из древнегреческого (syn - вместе, с и posis — пью). Ученые прекрасно это знают и сами. Syn звучит во множестве слов, например в симфонии + phone — голос.

Okay I'll downvote it - but only because it's been downvoted a lot already. I don't actually care how the military technology is going to play out on the battlefield in the next few years. And I already know that the world is going down the train, no need to remind me of it.
