<div dir="ltr">In a recent daf yomi (Succah 8) the gemara discusses the size of a circular succah. The rishonim further discuss various mathematical questions of the relationship of a square to a circle.<div><br></div><div>
Rav Stav based on this gemara asks several questions about the definition of learning Torah. Two possible applications would be a bracha and learning in the bathroom.</div><div><br></div><div>1) Learning in detail the rishonim discussing the mathematics of the length of a diagonal of a square and the area of a circle</div>
<div>Extension of these to learning higher math where it is applicable to real halachic question</div><div><br></div><div>2) learning about animals to define what is a terefah</div><div><br></div><div>3) learning astronomy for kiddush hachodesh (Rambam has a discussion of ancient astronomy)</div>
<div><br></div><div>4) learning Moreh Nevuchim and more generally Jewish philosophy</div><div><br></div><div>5) learning mussar and general ethics</div><div><br></div><div>He quotes from shut Chavot Yair #172 who has a lengthy discussion of Euclidian geometry with mathematical proofs (he seems to disagree with some - has anyone ever looked at his proofs?).</div>
<div>He discusses triangles and rectangles but notes he doesnt discuss pentagons etc.</div><div>In the end he apologizes for the lengthy treatment which is not the purpose of the responsa<br clear="all"><div>but he enjoys the topic</div>
