Why Nikola Tesla was the greatest geek who ever lived Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life.
20 Most Influential Women Intellectuals Women intellectuals have been playing an increasingly important role in shaping thought and culture. Here is SuperScholar’s list of the 20 most influential living women intellectuals. Margaret Atwood (1939– ), an iconic Canadian feminist novelist, expresses both the “goddess” and “activist” modes of the mid-twentieth century movement, via a confrontational style that gained converts by avoiding both violence and eccentricity. Aung San Suu Kyi (1945– ), a Nobel Peace Prize laureate and scholar living under house arrest and many other restrictions imposed by her native Burma’s (Myanmar’s) military rulers, leads a popular political movement and party whose non-violence and civil disobedience offer hope for eventual democratic government. Karen Armstrong (1944– ), formerly a Roman Catholic nun in her native Britain and widely considered a force for ecumenism, now considers herself a “creative monotheist,” whose many books offer iconoclasm regarding major monotheist religions.

Why is science important? - A collection of thoughts from leading scientists, public figures, ...and you. Why I decided to learn languages (14 and counting) Alex Rawlings, who won a competition to find Britain's most multi-lingual student in 2011, explains why learning foreign languages is so rewarding, and how his school helped set him on this path. The UK, my home country, can be a place of great contradictions. We’re famous for being reluctant to speak other languages and indignant about whether they even have a use. And yet, we live in an environment that is brimming with multiple languages and opportunities to speak them. Growing up in the UK surrounded by languages As a child, every bus journey inevitably took me on a quick whirl around the planet, with conversations in Spanish, Cantonese, Icelandic, and Urdu going on all around. School exchanges and other language opportunities I was fortunate to go to a school with a head teacher who believed in the importance of languages and made them compulsory for all. I went on several school exchanges to France and Germany, which were a real game changer for me.

toolbox Looking at Photographs of Marilyn Monroe Reading | Affidavit February 25, 2019 There are more photographs of Marilyn Monroe reading than there are of her naked. Almost always, these images are captioned with a kind of perky can-you-believe-it paternalism. “Those books aren’t just for show!” Beauty is a lot easier to prove than intelligence. In 1999, Christie’s auctioned off nearly 400 books from Marilyn’s personal library, a roster of classics ranging from Proust to Hemingway, which publicly solidified her intellectual identity and provided hard evidence against all those who claimed the plentitude of reading photographs were staged.1 But staged, of course, they were. To understand why there is such sustained, cultivated disbelief in her smarts, we must first understand how we came to believe she was dumb—iconically so. The archetype Monroe would come to define was barely sketched out as she began acting. In 1952, Howard Hawks cast her in Monkey Business, starring Hawks’ favorite Cary Grant and an Astaire-less Ginger Rogers.
The Meaning Organization By Umair Haque Welcome to the roaring teens. We’re in the aftermath of the worst economic crisis, many people argue, since the Great Depression. As mightily as governments, central banks, and scholars have labored, a jobless, fruitless, and suspiciously meaningless recovery has begun. Perhaps that's because the so-called Great Recession wasn't truly a recession at all. Ponder, for a moment, a troublesome paradox: The noughties (2000–2009) were a lost decade for America. A better and very different global economy made up of novel, more beneficial industries, more purposive types of organizations, and more passionate work will bring radically more fruitful approaches to commerce, trade, and exchange. In this era, it’s the ability to make up for the shortcomings of the prior decades—the belching, wheezing, crashing economic engine that gave us plenty materially, but has left us spiritually, relationally, emotionally, and developmentally empty. Enter, the Meaning Organization. Significance.
Open Science is Kinder Science | NCEAS Commentary: How open software can enable kinder culture IRL — and why we need this in science By Julie Lowndes. A version of this commentary was published originally in Scientific American. Photo provided by Julie Lowndes As a marine ecologist, I never expected I would one day advocate that science should operate more like the tech industry. This is not about “moving fast and breaking things.” Open software, both a driver and result of Silicon Valley’s success, has been game-changing for me as a scientist. But it is not only about the tool sets and skill sets. When I truly began learning the open source programming language R in 2014, I was part of a small team of marine ecologists who needed R to bring order to the chaos of repeating an annual and massive analysis of global ocean health. Otherwise intimidated and somewhat scarred by previous experiences coding on my own as a scientist, the kindness and inclusion I experienced from the open-source community was a revelation. Dr.
Angel "Java" Lopez en Blog Ya presenté los dos grandes protagonistas de la electrodinámica cuántica en: Introducción a la Electrodinámica Cuántica Eran el electrón y el fotón. Es sabido que en física se maneja el espacio y el tiempo, en lo que ha sido llamado algo ampulosamente el espaciotiempo. En el espacio, consideramos tres dimensiones, y le sumamos la del tiempo. La electrodinámica cuántica no escapa a ese esquema, pero en los diagramas que vamos a ver, los diagramas de Feynman, tomaremos una sola dimensión de espacio, por simplicidad. En los diagramas que viene, tomaremos un suceso como una posición en el tiempo y el espacio: El eje horizontal es el espacio, y el eje vertical representa el tiempo. La electrodinámica cuántica describe, mediante fórmulas, el comportamiento del electrón y el fotón. El que un electrón se mueva desde el punto a en el espaciotiempo al punto b, se dibuja con una línea contínua, que llamamos propagador. Ahora bien, esto no es lo único que nos interesa. Veamos otro diagrama: Nos leemos!
Why Anti-Authoritarians are Diagnosed as Mentally Ill (Note: Read Bruce Levine’s latest post: Anti-Authoritarians and Schizophrenia: Do Rebels Who Defy Treatment Do Better? In my career as a psychologist, I have talked with hundreds of people previously diagnosed by other professionals with oppositional defiant disorder, attention deficit hyperactive disorder, anxiety disorder and other psychiatric illnesses, and I am struck by (1) how many of those diagnosed are essentially anti-authoritarians, and (2) how those professionals who have diagnosed them are not. Anti-authoritarians question whether an authority is a legitimate one before taking that authority seriously. Evaluating the legitimacy of authorities includes assessing whether or not authorities actually know what they are talking about, are honest, and care about those people who are respecting their authority. Some activists lament how few anti-authoritarians there appear to be in the United States. Why Mental Health Professionals Diagnose Anti-Authoritarians with Mental Illness
