<div dir="ltr"><div>I disagree with R' David Riceman's assertion that his search for an O(n^2) algorithm for matrix multiplication is "na'arishkeit" that would wouldn't be engaged in by a "total oveid Hashem."</div>
<div><br></div><div>I see this activity as having inherent value, aside from the potential parnasah value and the value of having recreation activities, which have already been mentioned. First off, such an algorithm could be implemented and used in software that would be significantly more efficient (when n is very large) than what is currently available. This could enable the solving of problems that can't be efficiently solved by computer today, and that could have a direct positive impact on people's lives. Just like scientific research, abstract mathematical research can contribute to yishuvo shel olam. Even outside of research, I believe that most professions contribute something positive to society, even when the "contribution" seems indirect. If you are take any part in a system that enables society and the economy to function properly, which in turn enables people to live respectably, it seems self-evident that this has positive spiritual value. This is my kavanah in avodat Hashem as I go to work each day, in addition to the kavanah of providing for my family.</div>
<div><br></div><div>Yishuvo shel olam aside, I also see inherent value in learning math: it is truth. We learn Torah because it is revealed truth, and some of us study science because it is another reflection of the ways of Hashem, who is truth. The laws of math are objectively true, independent of their mapping onto the physical world. I remember that I once shocked a friend when I said that Hashem, notwithstanding His omnipotence and ability to change any of the laws of physics, cannot change the value of Pi. I don't mean changing the semantics -- anybody could say that a circle means something else, or that 3.14159 means something else -- but the value of Pi is objectively true, independent of the physical existence of the universe. I can't think offhand of a pasuk or maamar Chazal that makes this point explicitly, but it seems self-evident to me that studying such truths can help us to perfect the brains with which Hashem created us, and this has spiritual value.</div>
