What is defined as a mina?

A worthy question, and perhaps I will write a column about it. In general, there is book 11 in the Talmudic Logic series, Platonism of Talmudic Thought: http://www.collegepublications.co.uk/stl/?00012 This depends on the question of why a NAP is needed for Talmudic discussion. Whether to remove positivism or to clarify the sides, or to show that there is another practical implication, there is no Torah study here. See also Baran Sanhedrin 15:1-11, "How many Sinai bulls" written by Nefm for the vow of nuns, on the understanding that it is on the 23rd. Although the name of the NEPAM is not entirely one-sided. For some reason a person really wants to bring a sacrifice like in the wilderness, and therefore what happened in the wilderness must be discussed. It is not like a monk who vows on the knowledge of a Sinaitic bull on the 23rd. What's more, it is truly a NEPAM, but the time in which it is applied has already passed. It is not a NEPAM for us, but it is like Israel discussing the laws of the priests that are not a NEPAM for him. I once wrote in the Bar that I think he was joking, and in fact he claims that there is no need for a nefm. And so perhaps also in the Gemara during the celebration. We discuss a Torah passage and want to understand it. Why do we need a nefm?
