I know it's not like that but it would be cool if Sampo was just a mask the Fools took turns to wear. A shared persona, like Nicolas Bourbaki in mathematics (a pseudonym of a bunch of mathematicians and one of the most influential, even if nonexistant figures in 20th century mathematics).

The type of humour would fit too.

Humor has been an important aspect of the group's culture, beginning with Weil's memories of the student pranks involving "Bourbaki" and "Poldevia". For example, in 1939 the group released a wedding announcement for the marriage of "Betti Bourbaki" (daughter of Nicolas) to one "H. Pétard" (H. "Firecrackers" or "Hector Pétard"), a "lion hunter". Hector Pétard was itself a pseudonym, but not one originally coined by the Bourbaki members. The Pétard moniker was originated by Ralph P. Boas, Frank Smithies and other Princeton mathematicians who were aware of the Bourbaki project; inspired by them, the Princeton mathematicians published an article on the "mathematics of lion hunting". After meeting Boas and Smithies, Weil composed the wedding announcement, which contained several mathematical puns. Bourbaki's internal newsletter La Tribu has sometimes been issued with humorous subtitles to describe a given conference, such as "The Extraordinary Congress of Old Fogies" (where anyone older than 30 was considered a fogy) or "The Congress of the Motorization of the Trotting Ass" (an expression used to describe the routine unfolding of a mathematical proof, or process). During the 1940s–1950s, the American Mathematical Society received applications for individual membership from Bourbaki. They were rebuffed by J.R. Kline who understood the entity to be a collective, inviting them to re-apply for institutional membership. In response, Bourbaki floated a rumor that Ralph Boas was not a real person, but a collective pseudonym of the editors of Mathematical Reviews with which Boas had been affiliated. The reason for targeting Boas was because he had known the group in its earlier days when they were less strict with secrecy, and he'd described them as a collective in an article for the Encyclopædia Britannica. In November 1968, a mock obituary of Nicolas Bourbaki was released during one of the seminars.

Jorge Urrutia Galicia: A Mexican Pioneering Mathematician And Computer Scientist

Jorge Urrutia Galicia is a Mexican computer scientist and mathematician.

Galicia is best known for his work on geometry. He made contributions to many different areas of mathematics, including discrete geometry, discrete optimization, and computational geometry. His specialty in computational geometry has made him recognized as one of the leading researchers worldwide. His research has also focused on combinatorial optimization, which is related to combinatorial game theory.

His early works dealt with problems of separability and visibility, a field in which he is an indisputable authority. While it is clear that mathematics has always played a basic role as the underlying foundation of all technology, especially now, and in this case it is confirmed why the technological scope of Dr. Urrutia’s articles in routing is significant; suffice to mention just one: recently algorithms are being implemented based on the ideas of Dr. Urrutia, to make communication networks that can be used in case of natural disasters.

Since the end of the 20th century, he began to work on routing problems, developing algorithms for both the combinatorial and geometric problems, which literally founded a work area of great importance in its application to wireless and cellular networks. In the 21st century, Dr. Urrutia has also stood out for his numerous contributions to the study of discrete sets of points, on which he has made decisive contributions, both in their solution and formulating various variants.

Dr. Jorge Urrutia Galicia studied a bachelor’s degree in mathematics at the Faculty of Sciences of UNAM from 1971 to 1974, and a master’s and doctoral degree in mathematics at the University of Waterloo, Canada from 1976 to 1980. He has worked at the Metropolitan Autonomous University-Iztapalapa, CIMAT, Carleton University, Ottawa University from 1984-1998, where he was "full professor", and since 1998 at the Institute of Mathematics of the UNAM. On average, he teaches five courses each year (two undergraduate and three postgraduate courses).

Annually, he organizes at least two research workshops in Mexico, one of its main objectives being that its students know and work with renowned researchers and learn to collaborate with them as equals.

From 1990 to 2000, he was editor-in-chief of the journal Computational Geometry, Theory and Applications, published by Elsevier Science Publishers. He has been a member of the editorial boards of the Mexican Mathematical Society Bulletin and of Graphs and Combinatorics (Springer, and Computational Geometry: Theory and Applications (Elsevier). He was also editor of the Handbook of Computational Geometry (2000), one of Elsevier's first published handbooks.

He has published more than 270 articles in conference proceedings and research journals in mathematics and computing, which have received more than 6,000 citations, among the most important are two articles on routing in ad-hoc and wireless networks, which have received more than 2 600 citations together: “Compass Routing in Geometric Graphs” and “Routing with Guaranteed Delivery in Ad Hoc Wireless Networks.” In these investigations, Dr. Urrutia develops new strategies – highly efficient – to send information on wireless networks that take advantage of the characteristics obtained by recent technologies such as GPS, in addition to allowing them to travel through these networks effectively without having knowledge of their topology. It is worth mentioning that in 2012 he was the most cited mathematician of the UNAM.

He has given more than 40 plenary lectures at international congresses on Computational Geometry. He was editor-in-chief of "Computational Geometry, Theory and Applications" from 1990 to 2000. He has supervised more than 55 bachelor, master and doctoral theses.

In 2015, he received the "National University in Research in Exact Sciences" award at UNAM. He is is a member of the National System of Investigators, Level 3 He has organized and participated in the organizing committees of several national congresses including the "Victor Neumann-Lara Colloquium on Graphic Theory and its Applications", the "Canadian Conference on Computational Geometry", the "Japan Conference on Discrete and Computational Geometry" and the "Computational Geometry Meetings" (Spain). Oher countries where he has also participated in this way are Italy, Indonesia, Philippines, China, Canada, Peru and Argentina, as well as his home country, Mexico.

Edit: this is a real experiment you can do!

HISTORIC EXPERIMENT PROVES EARTH'S ROTATION

The famous experiment which proves that the "earth do move" by letting the observer actually see it twisting underneath his feet, an experiment invented by the French mathematician Jean B. L. Foucault nearly a century ago was repeated recently under unusually impressive circumstances before an international scientific congress at Florence, Italy, the same city where Galileo once was persecuted for holding the same opinion.

From the center of the dome of the Church of Santa Maria di Fiore, Father Guido Alfani, director of the Astronomical Observatory, suspended a 200-pound weight on a wire 150 feet long. On the bottom of this weight was a tiny projecting point which traced a line on a table-top sprinkled with sand, as the great pendulum swung slowly back and forth. At a given signal Father Alfani set the pendulum to swinging. While the assembled scientists watched it, slowly the line traced across the sand table-top changed direction.

As Foucault proved long ago and as the watching scientists well knew, the table was being twisted underneath the pendulum by the rotation of the earth.

some prumano as requested + a two cents worth ramble on klein’s encyclopedia and history of international congress of mathematicians :^)

Klein's encyclopedia is a German mathematical encyclopedia organized by Felix Klein and Wilhelm Franz Meyer. The encyclopedia is more strictly known as ‘Enzyklopädie der mathematischen Wisenschaften mit Einschluss ihrer Anwendungen’ (translation:  Encyclopedia of mathematical sciences including their applications)- or EMW for short. It was collectively written my many mathematicians.

Now, this project was not Klein’s first one. To shortly give an idea: at the beginning of the Franco-Prussian War, he was in Paris, as a part of completing Plücker's (who died before finishing) Neue Geometrie des Raumes, and had to leave the country. For a brief time he even served in the Prussian army.

But to get back to the topic- what this encyclopedia aimed to achieve was to present the core of contemporary mathematics with a detailed source of the historical development from the beginning of the nineteenth century. The project was published in six volumes, 23 books, from 1898 to 1933. It has 20,000 pages in total.

Walther von Dyck, who was a student of Felix Klein, was also the chairman of the commission to publish EMW. He also presented the project in 1908- to the International Congress of Mathematicians which was held in Rome that year.

Now, it cannot be argued that this congress was the most prominent one, but there were still many things accomplished that were prominent:

The greatest change from the previous ones was that it placed greater emphasis on applied mathematics.

It attempted to establish an International Mathematical Union, but failed. (It is important to note that, these congresses were not exactly ‘politic free’. After the end of World War 1, the congresses of 1920 and 1924 excluded the mathematicians from the nations of Central Powers.)

An International Commission on the Teaching of Mathematics was established. This would be, unlike the International Mathematical Union, highly successful.

It can be said that, these changes and progresses had similar principles with the goal of Klein’s encyclopedia and what it wanted to achieve.

While Klein’s encyclopedia was highlighted in the congress (and that was a big thing since ICM is a big event for mathematicians), even after the conference, it didn’t take its solid shape for a while (as the dates were mentioned above.) When the last volumes of the EMW published, the first entries were already more or less 30 years old. Some publications were postponed when World War 1 hit Europe. The preparation of the encyclopedia outlived the mathematicians who wrote and edited it.

In 1942 Øystein Ore, a Norwegian born American mathematician, underlined another trouble EMW brought: “The first encyclopedia was extremely expensive, and was for the most part supported by the subscribers of the libraries. Only few people could afford purchasing an entire encyclopedia. Even single volumes were not regularly sold as they were not generally affordable”. This was another reason why publishing the encyclopedia as a whole was not really as option for a while.

Anyways-

I need to accept that no one cares much about calculus and my English proficiency is equivalent to an average third graders. Also I already made a fool of myself a bit too much in these past few weeks already so I really need to shut up.

I still don't understand what these are.

Some of them are really weird.

HISTORIC EXPERIMENT PROVES EARTH'S ROTATION

The famous experiment which proves that the "earth do move" by letting the observer actually see it twisting underneath his feet, an experiment invented by the French mathematician Jean B. L. Foucault nearly a century ago was repeated recently under unusually impressive circumstances before an international scientific congress at Florence, Italy, the same city where Galileo once was persecuted for holding the same opinion.

On the bottom of this weight was a tiny projecting point which traced a line on a table-top sprinkled with sand, as the great pendulum swung slowly back and forth. At a given signal Father Alfani set the pendulum to swinging. While the assembled scientists watched it, slowly the line traced across the sand table-top changed direction.

As Foucault proved long ago and as the watching scientists well knew, the table was being twisted underneath the pendulum by the rotation of the earth.

A REVOLUTIONARY AIRPLANE

A new airplane propeller has recently been patented by J. Kalmanson of Brooklyn, N. Y. Greater speed and marked saving in fuel is claimed for the invention, which may be attached to any type of airplane.

The device is in two parts, which may be used separately as front and rear propellers or combined into a single blade. The principle is that the front one acts to bring air to the other, giving the propeller more of a hold, so to speak, and greater power. This is accomplished by four air-spoons, one on each side of each blade of the propeller.

It is said that the device can double the speed of an airplane and raise it from the ground in ninety feet instead of the 200 feet most airplanes now require. It is also claimed that the new propeller will prevent the plane from making a nose drive unless the pilot forces it to do so, and enable it to make a safe landing within a short distance. Because of the increase in power and speed, the device would save a large amount of gasoline and oil, as well as guarding the motor from part of the strain on it.

The device is said to be also applicable to ships, the same principle operating in water as well as air.

Father Guido Alfani seems to have been a real person at least.

some of the other random things like this are really absurd though.
