Omar Khayyam had any great belief in astrological predictions, nor have I seen or heard of any of the great [scientists] who had such belief. We have no document history for this standard. It involves weighing the compound both in air and in water, since weights are easier to measure exactly than volumes.

On the basis of all the existing textual and biographical evidence, the question remains somewhat open, [12]: The American historian of mathematics, David Eugene Smith mentions that Saccheri “used the same lemma as the one of Tusi, even lettering the figure in precisely the same way and using the lemma for the same purpose”.

The hypothesis of the acute, obtuse, and that of the right angle are now known to lead respectively to the non-Euclidean hyperbolic geometry of Gauss-Bolyai-Lobachevsky, to that of Riemannian geometryand to Euclidean geometry. As a mathematician, he is most notable for his work on the classification and solution of cubic equationswhere he provided geometric solutions by the intersection of conics.

This treatise on Euclid contains another contribution dealing with the theory of proportions and with the compounding of ratios.
