Because Euler didn't have the habit of "dismantling scaffolding" after Gauss finished his work, he kept all the motives and details, so that the latecomers could follow him regardless of IQ, so that everyone couldn't understand his work at all, and then he regarded Euler as a grounded tutor, instead of a genius who was above himself ... unconsciously forced him down (but would Euler care about these? Just kidding! )…

Comparing the styles of Euler and Gauss, we will find that they are very similar to Du Fu and Li Bai in Tang poetry. Li Bai has many fantastic ideas that want to surpass the times, and write them out one by one. It looks much cooler than Du Fu, so there are many fans-however, few people learn it because they can't find traces.

Then people think that Du Fu is much more grounded than Li Bai-especially there are laws to follow, which is convenient for self-study. However, as soon as you enter the door, you will find that behind the seemingly elementary rice (mathematical skills) is an amazing talent, while history dominates his materials (research problems).
