……这非常难，不是人人都搞得来的，普通大众根本看不懂，而在能看懂的人里，99% 也达不到 Felix Klein 或 Henri Poincaré 那种水平。《Indra's Pearls: The Vision of Felix Klein》这本书就是个绝佳例子，即便放在今天，受过专业训练的数学家也很难将 Klein 所描述的景象具象化。发帖的作者以为当年在哥廷根能有几个数学家光凭……
…it's very hard, it's not for everyone, the common folk cannot understand it, and 99% of those who can will not be on the level of a Felix Klein or Henri Poincaré. This is well exemplified in the book "Indra's Pearls: The Vision of Felix Klein", even today it's hard to trained mathematicians to visualize what Klein described. How many mathematicians does the author of the post supposed there was at Göttingen for just…
我忍不住想在这里安利一下 David Mumford 等人写的《Indra’s Pearls》这本书。
I feel compelled to plug the book Indra’s Pearls here, by David Mumford et al.
