For example, the rabbinical school of\u0000Beit Hillel says that one boy and one girl are necessary, whereas Beit Shammai\u0000urges for two boys. Surprisingly enough, although the corresponding average\u0000family sizes differ in both cases, the gender ratios remain constant. We show\u0000more that for any family planning rule the gender ratio is equal to the birth\u0000odds. The proof of this result is given by using different mathematical\u0000techniques, such as induction principle, Doob's optional-stopping theorem, and\u0000brute-force. We conclude that, despite possible asymmetries in the religiously\u0000motivated family planning rules, they discriminate neither boys nor girls.","PeriodicalId":501462,"journal":{"name":"arXiv - MATH - History and Overview","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematicians, philosophers, and theologians have\u0000all taken part. The basic question has been whether the infinite exists only in\u0000potential or exists in actuality. Only at the end of the 19th century, a set\u0000theory was created that works with the actual infinite. Initially, this theory\u0000was rejected by other mathematicians. The creator behind the theory, the German\u0000mathematician Georg Cantor, felt all the more the need to challenge the long\u0000tradition that only recognised the potential infinite. In this, he received\u0000strong support from the interest among German neothomist philosophers, who,\u0000under the influence of the Encyclical of Pope Leo XIII, Aeterni Patris, began\u0000to take an interest in Cantor's work. Gradually, his theory even acquired\u0000approval from the Vatican theologians. Cantor was able to firmly defend his\u0000work and at the turn of the 20th century, he succeeded in gaining its\u0000acceptance. The storm that had accompanied its original rejection now\u0000accompanied its acceptance. The theory became the basis on which modern\u0000mathematics was and is still founded, even though the majority of\u0000mathematicians know nothing of its original theological justification. Set\u0000theory, which today rests on an axiomatic foundation, no longer poses the\u0000question of the existence of actual infinite sets. The answer is expressed in\u0000its basic axiom: natural numbers form an infinite set. No substantiation has\u0000been discovered other than Cantor's: the set of all natural numbers exists from\u0000eternity as an idea in God's intellect.","PeriodicalId":501462,"journal":{"name":"arXiv - MATH - History and Overview","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141872504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
