نماد مربع که در پایان اثبات ها آورده میشود به هالموس منتسب است.
او اولین کسی است که در ریاضیات، این نماد را به کار برده است.
از این رو به افتخار هالموس، به این مربع، هالموس میگویند.

__________________________

در کتاب خاطراتش، "من میخواهم ریاضیدان شوم" خود او چنین نقل میکند که:
این نماد (نماد مربع) ابداع من نیست.
من آنرا در مجلات عمومی (که البته ریاضی نبوده اند) دیده ام، و جهت مشخص کردن پایان چیزی به کار میرفتند. اینطور به نظر می رسد که برای اولین بار من این نماد را به ریاضی وارد کرده ام.

Pythagoras of Samos
@harmoniclib

Greek Mathematician Pythagoras is considered by some to be one of the first great mathematicians. Living around 570 to 495 BC, in modern day Greece, he is known to have founded the Pythagorean cult, who were noted by Aristotle to be one of the first groups to actively study and advance mathematics. He is also commonly credited with the Pythagorean Theorem within trigonometry. However, some sources doubt that is was him who constructed the proof (Some attribute it to his students, or Baudhayana, who lived some 300 years earlier in India). Nonetheless, the effect of such, as with large portions of fundamental mathematics, is commonly felt today, with the theorem playing a large part in modern measurements and technological equipment, as well as being the base of a large portion of other areas and theorems in mathematics. But, unlike most ancient theories, it played a bearing on the development of geometry, as well as opening the door to the study of mathematics as a worthwhile endeavor. Thus, he could be called the founding father of modern mathematics.

Andrew Wiles
@harmoniclib

The only currently living mathematician on this list, Andrew Wiles is most well known for his proof of Fermat’s Last Theorem: That no positive integers, a, b and c can satisfy the equation a^n+b^n=c^n For n greater then 2. (If n=2 it is the Pythagoras Formula). Although the contributions to math are not, perhaps, as grand as other on this list, he did ‘invent’ large portions of new mathematics for his proof of the theorem. Besides, his dedication is often admired by most, as he quite literally shut himself away for 7 years to formulate a solution. When it was found that the solution contained an error, he returned to solitude for a further year before the solution was accepted. To put in perspective how ground breaking and new the math was, it had been said that you could count the number of mathematicians in the world on one hand who, at the time, could understand and validate his proof. Nonetheless, the effects of such are likely to only increase as time passes (and more and more people can understand it).
