El Problema de Gettier - “Is justified belief true knowledge?”

¿Excelente articulo del País sobre el Problema de Gettier, basado en su paper “Is justified belief true knowledge?”. Gettier demuestra que no es suficiente cumplir con las 3 condiciones del conocimiento enumeradas por Platón (para saber algo tenemos de:(i) creer en ello, (ii) la creencia debe ser cierta y (iii) la creencia debe ser justificada) es necesario un poco más. ¡Recomiendo su lectura! https://fitelson.org/proseminar/gettier.pdf?sma=filosofiainutil_2024.04.30_2&utm_medium=email&utm_source=newsletter&utm_campaign=filosofiainutil_2024.04.30_2 https://m.newsletter.elpais.com/nl/jsp/m.jsp?c=%403GoqW4iJRoVPaeXTRaFfR5rma1Bd6OJhIL%2Fy3NXa6%2FY%3D

Do Dice Play God?: The Mathematics of Uncertainty → Ian Stewart

Starting a new book! Do Dice Play God?: The Mathematics of Uncertainty → Ian Stewart A celebrated mathematician explores how math helps us make sense of the unpredictable We would like to believe we can know things for certain. We want to be able to figure out who will win an election, if the stock market will crash, or if a suspect definitely committed a crime. But the odds are not in our favor. Life is full of uncertainty --- indeed, scientific advances indicate that the universe might be fundamentally inexact --- and humans are terrible at guessing. When asked to predict the outcome of a chance event, we are almost always wrong. Thankfully, there is hope. As award-winning mathematician Ian Stewart reveals, over the course of history, mathematics has given us some of the tools we need to better manage the uncertainty that pervades our lives. From forecasting, to medical research, to figuring out how to win Let's Make a Deal , Do Dice Play God ? is a surprising and satisfying tour of what we can know, and what we never will.

PaTS-Wheel: A Passively-Transformable Single-Part Wheel for Mobile Robot Navigation on Unstructured Terrain

Do you need to reinvent the wheel? It seems so and T. Godden*, B. W. Mulvey*, E. Redgrave and T. Nanayakkara just did it :-) PaTS-Wheel: A Passively-Transformable Single-Part Wheel for Mobile Robot Navigation Very interesting concept that you can discover on the video below! Link to paper → https://ieeexplore.ieee.org/document/10502024 Abstract: Most mobile robots use wheels that perform well on even and structured ground, like in factories and warehouses. However, they face challenges traversing unstructured terrain such as stepped obstacles. This paper presents the design and testing of the PaTS-Wheel: a Passively-Transformable Single-part Wheel that can transform to render hooks when presented with obstacles. The passive rendering of this useful morphological feature is guided purely by the geometry of the obstacle. The energy consumption and vibrational profile of the PaTS-Wheel on flat ground is comparable to a standard wheel of the same size. In addition, our novel wheel design was tested traversing different terrains with stepped obstacles of incremental heights. The PaTS-Wheel achieved 100% success rate at traversing stepped obstacles with heights ≈70% its diameter, higher than the results obtained for an equivalent wheel (≈25% its diameter) and an equivalent wheg (≈61% its diameter). This achieves the design objectives of combining the energy efficiency and ride smoothness of wheels with the obstacle traversal capabilities of legged robots, all without requiring any sensors, actuators, or controllers. https://youtu.be/oZbZZlDDEnc?si=6euhl_-C0yGkODi-

Book Rating - 3/5 -> Fascism: A Warning

Book Rating - 3/5 Fascism: A Warning A must read specially nowadays! Review to come shortly. A personal and urgent examination of Fascism in the twentieth century and how its legacy shapes today’s world, written by one of America’s most admired public servants, the first woman to serve as U.S. secretary of state A Fascist, observes Madeleine Albright, “is someone who claims to speak for a whole nation or group, is utterly unconcerned with the rights of others, and is willing to use violence and whatever other means are necessary to achieve the goals he or she might have.” The twentieth century was defined by the clash between democracy and Fascism, a struggle that created uncertainty about the survival of human freedom and left millions dead. Given the horrors of that experience, one might expect the world to reject the spiritual successors to Hitler and Mussolini should they arise in our era. In Fascism: A Warning, Madeleine Albright draws on her experiences as a child in war-torn Europe and her distinguished career as a diplomat to question that assumption. Fascism, as she shows, not only endured through the twentieth century but now presents a more virulent threat to peace and justice than at any time since the end of World War II. The momentum toward democracy that swept the world when the Berlin Wall fell has gone into reverse. The United States, which historically championed the free world, is led by a president who exacerbates division and heaps scorn on democratic institutions. In many countries, economic, technological, and cultural factors are weakening the political center and empowering the extremes of right and left. Contemporary leaders such as Vladimir Putin and Kim Jong-un are employing many of the tactics used by Fascists in the 1920s and 30s. Fascism: A Warning is a book for our times that is relevant to all times. Written by someone who has not only studied history but helped to shape it, this call to arms teaches us the lessons we must understand and the questions we must answer if we are to save ourselves from repeating the tragic errors of the past. https://www.goodreads.com/book/show/35230469
