It is not difficult to imagine the amazement with which Engel read Killing's letter with its bold conjectures. here was an obscure professor at a Lyceum dedicated to the training of clergymen in the far-away reaches of east Prussia, discoursing with authority and conjecturing profound theorems on Lie 's theory of transformation groups, a theory which had seemed an area of mathematics known to relatively few mathematicians and mastered by even fewer.
Ito ay hindi mahirap sa diwa ng labis na kung saan Engel basahin ang pagpatay ng sulat sa kanyang bold conjectures. dito ay isang propesor sa isang hindi tanyag Lyceum alay sa pagsasanay ng clergymen sa malayo-layo na umabot ng east Prussia, discoursing na may awtoridad at conjecturing kalaliman theorems sa humiga / magsinungaling 's theory ng mga grupo ng pagbabagong-anyo, ang isang theory na kung saan nagkaroon seemed ng isang lugar ng matematika na kilala sa medyo ilang mga mathematicians at mastered kahit na sa pamamagitan ng mas kaunti.
