Quaternions Came From Hamilton After His Really Good Work Had Been Done, And Though Beautifully Ingenious, Have Been An Unmixed Evil To Those Who Have Touched Them In Any Way.

But Nearly All The Grandest Discoveries Of Science Have Been But The Rewards Of Accurate Measurement And Patient Long-continued Labour In The Minute Sifting Of Numerical Results.
