While mathematics geniuses such as Newton, Leibniz and Euler deserve to be acclaimed for their voluminous ground-breaking achievements, we should not forget the signal contributions of some of their predecessors in mathematics. François Viète (1540–1603) was a French lawyer, politician, diplomat and amateur mathematician. One of his many mathematical contributions is the expression of π as an infinite product involving only the integer 2, in an infinite nesting of square roots. Viète’s expression marked a milestone in the history of mathematics. It was the first equation incorporating the concept of an infinite process, even though it was not explicitly spelt out as such. The dots (…) in the equation denotes continuing the process indefinitely. If we think that the expression looks difficult, remember Viète published it in 1593, more than four hundred years ago!

Corredor sostiene que la red eléctrica española no está saturada mientras se rechazan el 90% de los proyectos industriales por falta de capacidad de conexión. Málaga ha perdido por ello una inversión tecnológica de 2.000 millones.

M. Teresa Ginés Orta, que fue profesora en Cataluña durante muchos años, nos ha enviado este estudio titulado «El papel de la escuela en el auge del nacionalismo en Cataluña» con la petición de que le demos difusión. Lo hacemos encantados. #HablamosEspañol hispanohablantes.es/el-papel-de-la…

Se hizo un primer acta en la que se suspendía a todos los candidatos y le daban la plaza al hermano. Como cantaba mucho, hicieron una segunda en la que aprobaban a 6 de 11.. y le daban la plaza al hermano. Siempre salía elegido el hermano, qué suerte.

El @Gob_eus sitúa el euskera como lengua de convivencia y cohesión social, en una sociedad cada vez más diversa. ¿Cohesión? ¿diversidad? En #HablamosEspañol recibimos continuas quejas de familias hispanohablantes con hijos sometidos a inmersión en euskera euskadi.eus/gobierno-vasco…

Si no es por los pseudomedios, Ábalos seguiría siendo ministro, Cerdán secretario de organización, Koldo pisaría a diario la moqueta de la Moncloa, el hermano de Sánchez estaría en la Filarmónica Nacional y Begoña sería honoris causa de la Complutense.

Qué alegría tengo de esto, la afición crece enormemente , somos jóvenes pero vamos poco a poco a escribir la historia de nuestra tierra

A computer scientist won the Turing Award at 36 and then walked away from almost every other project for the next 50 years to write one book that he has still not finished at age 88, and it may be the most important book in his field. His name is Donald Knuth. He won the Turing Award in 1974, which is the closest thing computer science has to a Nobel Prize. He was 36 years old. He had already written volumes one, two, and three of a book series called The Art of Computer Programming. He was the youngest person ever to receive the award at that point in its history. Almost anyone else would have ridden that moment for the rest of their career. Founded a company. Sat on boards. Gone on speaking tours. Knuth did the opposite. He went back to his desk and kept writing. He started the book in 1962. He was 24 years old. His publisher had asked him to write a short paperback on compilers. He sat down to outline it and discovered that to explain compilers properly he would have to explain the deeper algorithms underneath them first. The short paperback became a draft outline of 12 chapters. The 12 chapters became a planned 7-volume series. The 7-volume series became the project he is still working on 63 years later. Volume 1 came out in 1968. Volume 2 in 1969. Volume 3 in 1973. He was producing books faster than most academics produce papers. Then everything stopped. In 1977 he received the printed proofs of the second edition of Volume 2. He looked at the pages and was so disgusted by how the publisher had typeset his mathematical notation that he could not bring himself to release the book. The equations looked ugly. The fonts looked wrong. The spacing was off. He decided he could not in good conscience publish another volume of TAOCP until the typesetting problem was solved. So he paused the book. He stopped writing TAOCP and spent the next 8 years inventing TeX from scratch. TeX is the typesetting system that every academic paper, every math textbook, every physics journal on earth now uses. Every PhD thesis in the sciences is set in TeX. Every paper on arxiv. Every equation in every paper Anthropic, OpenAI, and DeepMind have ever published. The system that the entire scientific publishing world runs on exists because one man refused to compromise on how the second edition of Volume 2 looked. He gave the entire TeX system away for free. He never tried to commercialize it. He went back to writing TAOCP. In 1992 he retired from Stanford at the age of 54. Most professors retire to slow down. Knuth retired to speed up. He explicitly said he was leaving teaching because he needed every remaining hour of his life to keep writing the book. He stopped using email on January 1, 1990. He answers no calls. He takes paper mail only. He is on a personal mission to finish a multi-volume series that nobody is forcing him to write, on a deadline that only exists in his own head. Volume 4A came out in 2011. Volume 4B in 2022. He is currently working on Volume 4C. Volumes 4D, 4E, 4F, 5, 6, and 7 are still ahead of him. He is 88 years old. He will almost certainly die before he finishes. The thing that should haunt anyone reading this is the math of his choice. Every modern incentive structure tells you to optimize for speed. Ship the imperfect version. Get it out the door. Iterate later. Move on to the next thing. Knuth has spent 63 years doing the exact opposite. He pays a $2.56 reward in hexadecimal dollars to anyone who finds an error in his published books. Real checks, until check fraud made him switch to certificates of deposit. He treats every single error in every single volume as a personal failure. He revises. He rewrites. He goes back to fix issues that nobody else could have spotted. He could have written 30 books in 63 years. He chose to write one. The reason is the one almost nobody understands the first time they hear it. There is a category of work that loses all its value when it is done quickly. A reference book that engineers will rely on for the next 200 years is not the same kind of object as a blog post that has to ship today. The slow project and the fast project look like the same activity from the outside. They are completely different games. Bill Gates once said in an interview that if you can read the whole of TAOCP, you should send him your resume. He meant it. He was not joking. The man who founded Microsoft was telling the world that the rarest skill on earth is being able to finish a book that one man has spent his entire adult life writing for an audience that mostly does not have the patience to read it. The book may never be finished. The man writing it knows this and keeps writing anyway. The work outlives the worker. That is the entire point.

Ojalá le pueda llegar esto a Rubi o a los jugadores. Aquí un hilo de virtudes y defectos del Castellón, nuestro rival en Play-off

Los 2 centrales tanto Alberto como Brignani son bastante torpes con el balón y cometen muchos errores en salida, si se les aprieta podemos encontrar situaciones de mano a mano. Aquí os dejo 3 ejemplos

Pedro Sánchez lo ha sabido siempre. Y, como vemos, ha participado en la toma de decisiones.

Y por eso, hay que estar unidos este Play Off. Ya hablamos del entrenador en verano. TODOS A UNA
