Karen Uhlenbeck, first woman winner of the 'Nobel' of mathematics

The American Karen Keskulla Uhlenbeck has become the first woman to win the Abel Award, a recognition considered to be the 'Nobel of mathematics', in the decade and a half of the award's history.

The Norwegian Academy of Sciences and Literature stressed that Uhlenbeck, attached to the University of Austin (USA), is one of the founders of modern geometric analysis and that her perspective has been implemented in mathematics and has led to some of the "most spectacular" advances in that field in the last 40 years.

The techniques and methods of global analysis developed by Uhlenbeck are part of "the toolbox of every geometer and analyst" and their work is also the basis of contemporary geometric models applied in mathematics and physics. "Her theories have revolutionized our understanding of minimal surfaces, such as that formed by soap bubbles, and general minimization problems in higher dimensions," said committee chairman Hans Munthe-Kaas.

Matefest

Mathematics and computer science can seem complicated subjects, only within the reach of brains or people who do not raise their elbows from the study table. But ... what if we could discover its most playful part? Maybe then everything would change and we would find them unthinkable attractions. To this end, the Faculty of Mathematics and Computer Science of the University of Barcelona (UB) has been organizing Matefest for 20 years to show its multiple applications and explain them as they have never been explained.

The students themselves decide what topics are dealt with and what the various positions that are installed in the building's Pati de Ciències are dedicated throughout the day, from 9 a.m. to 2:00 p.m. The events are open to the public in general and have a festive and informative purpose, especially designed for young people who can join this career. We can get closer and they will make us participate in various activities around the subjects dealt with.

The topics are very interesting. Among them we find Neotrie VR (which shows the possibilities of virtual reality to generate geometry in three dimensions), three logical paradoxes, probability or luck? (a proof that some issues that we believe depend on luck, actually are very justifiable knowing the rules of probability), strategy games, topology, fractals (a geometric structure that maintains its shape but varies the scale of observation) or free hacking (on computer security and the need to stimulate the use and creation of open codes).

The wonderful lesson of a 7 year old child to his teacher

Impeccable, funny and intelligent. This is how a seven-year student solved a mathematics exercise. It is not the first time, nor the last, that an ambiguous statement brings out a teacher through a wonderful (future) mind.

His name is Jaime, he is seven years old and he is a crack. Who knows if a new Euclid, Newton or Gauss, ... or, sweeping for home, Echegaray, Torroja or Catalá, ...

The fact is that Jaime's father, a mining engineer, wanted to share on Twitter the wonderful work of his son. A mathematics exercise impeccably solved (except for some clueless teacher).

Even at first glance it is difficult to identify Jaime's genius. The same thing that should have happened to his teacher. The answer is not correct when it is the same exercise (with a bad statement) that you have put throughout your life to thousands of students who have answered the same.

'The following numbers' can also mean 'the numbers correlative to those proposed in the statement', and that is what Jaime interpreted, writing them in figures.



The tweet has been viralized in hours. More than 13,000 shares and 22,000 likes for an account with few updates. The proof that the reader sympathizes with an intelligent student and capable of seeing and interpreting reality in an original and different way than the majority does.

"We teach children to hate mathematics before we start studying them"

The Sevillian Clara Grima is a reference in the dissemination of mathematics. His crusade to combat hatred of numbers now comes in the form of a freaky book, "May Mathematics Be with You!"

If you follow closely the agenda of the mathematics and disseminator Clara Grima understands why the screenwriters of a certain television program baptized her in her day as the "red whirlwind". In addition to his classes at the University of Seville, he organizes lectures, lectures, awards, participates in plays and is behind some of the most successful scientific dissemination initiatives in Spanish. In a few years, the tireless work of this PhD in Mathematics has done more to improve the image of this discipline than many institutions.

4 colors = a map

Is it true that 4 colors are enough to paint any map without any neighboring country having the same color? The question seems banal, but the enigma has overshadowed more than one great mathematical mind and until recently it could be solved. Can you?

How many colors are really needed to paint a map so that no country is left with the same color? It is very likely that this question has never been raised, and that it seems to be an issue of exclusive interest to the cartographers.

However, that question, so simply described but so difficult to prove, was for more than a century one of the most difficult to solve in mathematics, and put to the test some of the most imaginative minds, including that of the mathematician and author of "Alice in Wonderland", Lewis Carrol. And it turns out that, mathematically, the answer is 4.

Girls gamers synonymous with scientists

A study in the United Kingdom found a close relationship between a taste for video games from an age and a vocation for science and technology. Will it be the key to ending gender inequality in these areas of knowledge?

One of the great problems of equity in education in practically the whole world is how to attract more women to careers related to Science, Technology, Engineering or Mathematics. After centuries of inequality, the number of women enrolled in a university has finally equaled that of men, but their participation in the areas of Science and Technology is still very scarce. All over the world, only 35% of those enrolled are women, according to Unesco estimates.

However, a study by the University of Surrey, in the United Kingdom, found a great strategy to encourage them: video games.

According to the researchers, girls who between 13 and 14 years of age played video games intensively (on average more than nine hours a week) were then 3.3 times more likely to enroll, after several years, in a STEM degree (those related to Science, Technology, Engineering or Mathematics, for its acronym in English).

The conclusion of the study is that girls interested in videogames self-identify as 'geeks' (a term used to refer to people who are fond of technology and computer science), which brings them closer to science, technology and mathematics.

From today the kilo is no longer what you knew until now

This May 20, 2019 is a historical day: the kilo, as we have known it for 130 years, ceases to exist forever. And this is because the new definition of the International System of units of measure (known as SI) for the kilogram comes into force.

It is not the only novelty: in addition to the way in which we calculate the mass, the basic unit of temperature, of the intensity of the electric current and of the substance will also be different.

From today, all these measures will be based on universal constants, which are, by definition, invariable. So that a kilo, an ampere or a kelvin are the same in a laboratory in Spain as in a scientific basis accommodated in Mars.
