These classroom notes offer methods of solving the quadrature of lunes, that is, the area of croissant-shaped plane figures bounded by two intersecting non-congruent circular arcs, using Hippocrates of Chios’ area conservation and similarity arguments. I also offer a method of using history in the classroom with students via dynamic geometry snapshots presented in a manner that complements the analytic and the visual approaches.
这些课堂笔记提供了解决月相正交的方法,即由两个相交的不全等圆弧包围的羊角形平面图形的面积,使用希俄斯的希波克拉底的面积守恒和相似性论点。我还提供了一种在课堂上与学生一起使用历史的方法,通过动态几何快照以补充分析和视觉方法的方式呈现。

In this paper we examine two mathematicians who published manuscripts on geometry and origami in the same year, 1893: Hermann Wiener and Sundara Row. The main question that concerns us is to situate these works in the correct historical and mathematical background. We suggest that Wiener and Row offer us, via folding a piece of paper, a new conception of geometry that is very different to the common conception at the time.
在本文中,我们考察了两位数学家谁发表手稿几何和折纸在同一年,1893年:赫尔曼维纳和Sundara Row。我们关心的主要问题是把这些著作置于正确的历史和数学背景中。我们认为,维纳和罗通过折叠一张纸,为我们提供了一个新的几何概念,它与当时的常见概念非常不同。

Robert Leslie Ellis, William Whewell and Kant: the role of Rev H F C Logan 罗伯特·莱斯利·埃利斯,威廉·休威尔和康德:H·F·C·罗根牧师的角色

Reverend H F C Logan is put forward as the formerly unidentified figure to which Robert Leslie Ellis referred in a journal entry of 1840 in which he wrote that it was due to his influence that William Whewell came to uphold particular Kantian views on time and space. The historical evidence of Ellis’s early familiarity with, and later commitment to Kant is noteworthy for at least two reasons. Firstly, it puts into doubt the accepted view of the second generation of reformers of British algebra as non-philosophical, practice-oriented mathematicians. Secondly, in so far as Logan was the correspondent of William Rowan Hamilton, it re-emphasizes that the role of Kantianism in the transition from ‘symbolical’ to ‘abstract’ algebra in nineteenth-century British algebra requires closer scrutiny.
H·F·C·洛根牧师是罗伯特·莱斯利·埃利斯在1840年的一篇日记中提到的一个以前身份不明的人物,他在日记中写道,由于他的影响,威廉·休威尔开始坚持康德关于时间和空间的观点。埃利斯早期对康德的熟悉和后来对康德的承诺的历史证据值得注意,至少有两个原因。首先,它使人们对公认的第二代英国代数改革者是非哲学的、以实践为导向的数学家的观点产生了怀疑。其次,就罗根与威廉·罗文·汉密尔顿的通信而言,它再次强调了康德主义在19世纪英国代数从“象征”到“抽象”的过渡中所扮演的角色,需要更仔细的审视。

A tale of mathematical myth-making: E T Bell and the ‘arithmetization of algebra’† 一个制造数学神话的故事:贝尔和“代数的算术化”†
Pub Date : 2016-01-02 DOI: 10.1080/17498430.2015.1048640
Christopher D. Hollings
Throughout E T Bell’s writings on mathematics, both those aimed at other mathematicians and those for a popular audience, we find him endeavouring to promote abstract algebra generally, and the postulational method in particular. Bell evidently felt that the adoption of the latter approach to algebra (a process that he termed the ‘arithmetization of algebra’) would lend the subject something akin to the level of rigour that analysis had achieved in the nineteenth century. However, despite promoting this point of view, it is not so much in evidence in Bell’s own mathematical work. I offer an explanation for this apparent contradiction in terms of Bell’s infamous penchant for mathematical ‘myth-making’.
在贝尔关于数学的著作中,无论是针对其他数学家的还是针对普通读者的,我们都发现他在努力推广抽象代数,特别是公设方法。贝尔显然认为,采用后一种代数方法(他称之为“代数的算术化”的过程)将使这门学科具有类似于分析学在19世纪所达到的严谨程度。然而,尽管推广了这一观点,但在贝尔自己的数学工作中却没有那么多证据。对于这个明显的矛盾,我用贝尔臭名昭著的数学“造神话”癖好来解释。

Theodorus’ proofs of incommensurabilities with Gnomons 狄奥多罗斯用悟性证明不可通约性
Pub Date : 2016-01-02 DOI: 10.1080/17498430.2015.1055156
S. Negrepontis, G. Tassopoulos
An ‘infinite decreasing sequence of Gnomons’ is characteristic, according to Proclus, of incommensurability, hence David Fowler's idea to reconstruct Theodorus’ proofs of incommensurabilities, reported in the Theaetetus147d, employing Gnomons, is attractive and solidly based. The ‘preservation of the shape of the Gnomons’ is a form of the Pythagorean principle of the Limited according to Aristotle. In the present paper we propose a reconstruction that employs Gnomons but is free of the drawbacks present in Fowler's reconstruction.
根据普罗克罗斯的说法,一个“无限递减的Gnomons序列”是不可通约性的特征,因此大卫·福勒在《Theaetetus147d》中报道的重建Theodorus不可通约性证明的想法,使用Gnomons,是有吸引力和坚实基础的。按照亚里士多德的说法,“保持地神的形状”是毕达哥拉斯的有限原则的一种形式。在本文中,我们提出了一种使用侏儒的重建,但没有福勒重建中存在的缺点。

You will not see Robert Patterson’s name mentioned in many mathematics books. While his mathematical works survive, his name is more likely to appear in American history books dealing with the Colonial period, given his associations with the most influential men of that time. In this article, we will examine his mathematical work, as well as his contributions to a newly-formed nation. Most of what we know about Robert Patterson’s ancestors and life is due to his grandson, William Ewing DuBois, who wrote a family history in 1847. For other information, I have drawn upon diaries and a great many letters. All spelling and syntax are copied exactly as they appear.
你不会在许多数学书籍中看到罗伯特·帕特森的名字。虽然他的数学著作流传了下来,但他的名字更有可能出现在有关殖民时期的美国历史书中,因为他与当时最有影响力的人有联系。在这篇文章中,我们将研究他的数学工作,以及他对一个新成立的国家的贡献。我们对罗伯特·帕特森的祖先和生活的大部分了解都要归功于他的孙子威廉·尤因·杜波依斯,他在1847年写了一本家族史。至于其他资料,我从日记和许多信件中得到。所有的拼写和语法都被精确地复制。

This two-part paper investigates the discovery of an intriguing and fundamental connection between the famous but apparently unrelated mathematical work of two late third-century mathematicians, a link that went unnoticed for well over 1500 years. In this, the first installment of the paper, we examine the initial chain of mathematical events that would ultimately lead to the discovery of this remarkable link between two seemingly distinct areas of mathematics, encompassing contributions by a variety of mathematicians, from the most distinguished to the relatively unknown.
这篇由两部分组成的论文调查了三世纪晚期两位数学家的著名但显然不相关的数学作品之间一个有趣而基本的联系,这个联系被忽视了1500多年。在本文的第一部分中,我们考察了最初的数学事件链,这些事件最终导致发现两个看似不同的数学领域之间的这种显著联系,包括各种数学家的贡献,从最杰出的到相对不为人知的。

BSHM-LMS De Morgan Day BSHM-LMS De Morgan Day
Pub Date : 2015-09-02 DOI: 10.1080/17498430.2015.1055089
T. Crilly
T he BSHM was co-sponsor of this De Morgan meeting commemorating the 150th anniversary of the setting up of the London Mathematical Society (LMS). Augustus De Morgan was its first president, the society inspired by students A C Ranyard and George De Morgan, the ‘mathematical son’ of Augustus. The meeting began with a welcome from the two current presidents, Terry Lyons (for the LMS) and Philip Beeley (for the BSHM). It was fitting that the De Morgan meeting took place in ‘his’ building, located not more than half a mile from the place where the inaugural meeting took place, the meeting at which he presided. We were reminded of the traditions of the society when two participants signed the LMS book and formally became members. Following an overview of De Morgan’s life, we were treated to lectures on aspects of his life in mathematics and logic. He was a great letter writer, and there were talks on his correspondence with George Boole and Ada Lovelace, and lectures on his role in setting up the LMS, his writing of the Budget of Paradoxes and his influence on modern thought. As an introduction, Adrian Rice spoke on De Morgan’s life and work. As he noted De Morgan is perhaps best remembered for the laws that bear his name: the famous De Morgan laws linking union, intersection, and complement of sets, the laws which appear in just about all modern textbooks. That De Morgan was the first discoverer of these is open to historical dispute, and given this tenuous link, what else should De Morgan be remembered for? In recent decades, research has shed light on forgotten aspects of his life and associations giving us a more complete picture of the range and diversity of his mathematical activities, and not least his personality. He always insisted on being De Morgan (and not de Morgan), declined membership of the Royal Society, and, in an age when the Anglican Church was all powerful, described himself as a ‘Christian unattached’. As the meeting progressed De Morgan emerged as a man of singular character. The lecture by Chris Hollings delved into De Morgan’s correspondence with Ada King, Countess of Lovelace, the daughter of Lord Byron. Previous readings of this correspondence, in which De Morgan adopted the role of teacher, have resulted in wildly differing assessments of her mathematical abilities. Here it was argued that she lay somewhere around half-way between the extremes of ‘hopeless’ and ‘mathematical genius.’ Of De Morgan’s publications on general mathematics, his Budget of Paradoxes was best known in his day, and it is still a good read. It was a natural outgrowth of his book reviews published in the weekly London-based literary magazine, The Athenæum. Sloan Despeaux’s talk included sample episodes associated with the amateurs and cranks of Victorian England bound together for all to enjoy. Top of the pile must be James Smith, a Liverpool merchant and Arch-Paradoxer, the king of the circle-squarers. He spent much of his retirement insisting that t
BSHM是纪念伦敦数学学会(LMS)成立150周年的德摩根会议的共同赞助者。奥古斯都·德·摩根(Augustus De Morgan)是该协会的首任主席,该协会的灵感来自学生A·C·兰亚德和奥古斯都的“数学之子”乔治·德·摩根(George De Morgan)。会议以两位现任主席特里·莱昂斯(LMS的主席)和菲利普·比利(BSHM的主席)的欢迎开始。德·摩根的会议在“他的”大楼里举行是再合适不过的了,这座大楼离他主持的就职会议举行的地方不到半英里。当两名参与者在LMS书上签名并正式成为会员时,我们想起了这个协会的传统。在概述了德·摩根的生平之后,我们听取了他在数学和逻辑方面的生平讲座。他是一个伟大的书信作家,有关于他与乔治·布尔和阿达·洛夫莱斯的通信的讲座,也有关于他在建立LMS中的作用的讲座,他写的《悖论预算》以及他对现代思想的影响。作为开场白,阿德里安·赖斯讲述了德·摩根的生活和工作。正如他所指出的,德·摩尔根最为人所铭记的也许是以他的名字命名的定律:著名的德·摩尔根定律,它将集合的并集、交集和补集联系起来,这些定律几乎出现在所有现代教科书中。德·摩尔根是这些理论的第一个发现者,这在历史上是有争议的,鉴于这种微弱的联系,德·摩尔根还应该被人们记住什么呢?近几十年来,研究揭示了他的生活和交往中被遗忘的方面,使我们更全面地了解了他的数学活动的范围和多样性,尤其是他的个性。他一直坚持自己是德·摩根(而不是德·摩根),拒绝成为皇家学会的会员,在英国国教势力强大的时代,他称自己为“独立的基督徒”。随着会谈的进行,德·摩根成为了一个性格独特的人。克里斯·霍林斯的讲座深入探讨了德·摩根与拜伦勋爵的女儿、洛夫莱斯伯爵夫人艾达·金的通信。在之前的阅读中,德摩根扮演了老师的角色,对她的数学能力产生了截然不同的评价。在这里,人们认为她介于“绝望”和“数学天才”这两个极端之间。在德·摩尔根关于一般数学的著作中,他的《悖论预算》在他那个时代最为著名,至今仍是一本好书。这是他在伦敦文学周刊《the Athenæum》上发表书评的自然结果。斯隆·德斯波的演讲包含了一些与维多利亚时代英国的业余爱好者和怪人有关的例子,供所有人欣赏。排在第一位的一定是詹姆斯·史密斯,他是利物浦商人,也是最大的悖论者,是圆方之王。他退休后的大部分时间都坚持认为p的真正价值是

He was a great letter writer, and there were talks on his correspondence with George Boole and Ada Lovelace, and lectures on his role in setting up the LMS, his writing of the Budget of Paradoxes and his influence on modern thought. As an introduction, Adrian Rice spoke on De Morgan’s life and work. As he noted De Morgan is perhaps best remembered for the laws that bear his name: the famous De Morgan laws linking union, intersection, and complement of sets, the laws which appear in just about all modern textbooks. That De Morgan was the first discoverer of these is open to historical dispute, and given this tenuous link, what else should De Morgan be remembered for? In recent decades, research has shed light on forgotten aspects of his life and associations giving us a more complete picture of the range and diversity of his mathematical activities, and not least his personality. He always insisted on being De Morgan (and not de Morgan), declined membership of the Royal Society, and, in an age when the Anglican Church was all powerful, described himself as a ‘Christian unattached’. As the meeting progressed De Morgan emerged as a man of singular character. The lecture by Chris Hollings delved into De Morgan’s correspondence with Ada King, Countess of Lovelace, the daughter of Lord Byron. Previous readings of this correspondence, in which De Morgan adopted the role of teacher, have resulted in wildly differing assessments of her mathematical abilities. Here it was argued that she lay somewhere around half-way between the extremes of ‘hopeless’ and ‘mathematical genius.’ Of De Morgan’s publications on general mathematics, his Budget of Paradoxes was best known in his day, and it is still a good read. It was a natural outgrowth of his book reviews published in the weekly London-based literary magazine, The Athenæum. Sloan Despeaux’s talk included sample episodes associated with the amateurs and cranks of Victorian England bound together for all to enjoy. Top of the pile must be James Smith, a Liverpool merchant and Arch-Paradoxer, the king of the circle-squarers. He spent much of his retirement insisting that t","PeriodicalId":211442,"journal":{"name":"BSHM Bulletin: Journal of the British Society for the History of Mathematics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124071066","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}
