We Are Singing Stardust: Carl Sagan on the Story of Humanity’s Greatest Message and How the Golden Record Was Born by Maria Popova “We [are] a species endowed with hope and perseverance, at least a little intelligence, substantial generosity and a palpable zest to make contact with the cosmos.” In 1939, just before his fifth birthday, Carl Sagan visited the New York World’s Fair, where he marveled at the Time Capsule evincing the fair’s confidence in the future — a hermetically sealed chamber, filled with newspapers, books and artifacts from that year, buried in Flushing Meadows to be revisited in some far-off future era by a future culture very different from and curious about the present. Sagan, in his characteristic eloquence, writes of the motivation, offering a poetic, humbling, and timelier than ever reminder of just how misplaced our existential arrogance is:
Five Mathematics Glossaries for Kids A glossary of mathematics terms can be a helpful aid to students who struggle with the vocabulary of mathematics. When I was a middle school and high school student the vocabulary of math often tripped me up and having a glossary of terms often helped me be able to complete my homework assignments. Here are five mathematics glossaries that students can access online. The McGraw Hill Mathematics eGlossary provides written and verbal definitions and explanations of mathematics terms. The glossary is divided by grade level.
What Is the Higgs? - Interactive Graphic Imagine never having seen a snowflake. Now prove one exists by probing the slush and mist of melting snow. You can’t see a Higgs boson, and no sensor can pick one out from the Higgs field that it forms. For 50 years, physicists have been building larger and more powerful accelerators to vaporize particles and sift through the debris.
The Science of Our Optimism Bias and the Life-Cycle of Happiness by Maria Popova “To make progress, we need to be able to imagine alternative realities, and not just any old reality but a better one.” “If I expect as little as possible, I won’t be hurt,” Susan Sontag famously wrote in her diary. And yet we’re wired to expect a lot — and to expect great things. So argues neuroscientist Tali Sharot in The Science of Optimism: Why We’re Hard-Wired for Hope — a short, absorbing TED Book summarizing Sharot’s own research, as well as that of others in the field, using a combination of neuroimaging and behavioral science to explore why we’re “more optimistic than realistic,” what this might mean for our everyday well-being, and whether it’s due to the specific architecture of our brains. The root of optimism, Sharot suggests, isn’t far from what Montaigne argued five centuries ago.
Mathematics in English “What does algebra have to do with learning English?” you might ask. Many people believe that nothing. In fact many wrongly believe that you can be good either at maths or at English. Creationism Is Not Being Ignored On 'Cosmos' By Betsy Phillips, Guest Contributor "Creationism Is Not Being Ignored On ‘Cosmos’ — It’s Actually The Focus" CREDIT: Frank Micelotta/Invision for FOX/AP Images Danny Faulkner, a “scientist” working for the same group that runs Kentucky’s creation museum was complaining last week that Neil deGrasse Tyson’s Cosmos: A Spacetime Odyssey doesn’t address creationism. From Mashable: Faulkner claimed the 13-episode series has a distinct “evolutionary bias,” and agreed with Mefferd’s concern that Cosmos doesn’t even present creationism as an alternative theory.
Sleep and the Teenage Brain by Maria Popova How a seemingly simple change can have a profound effect on everything from academic performance to bullying. “Sleep is the greatest creative aphrodisiac,” Debbie Millman asserted in her advice on breaking through your creative block. “Sleep deprivation will profoundly affect your creativity, your productivity, and your decision-making,” Arianna Huffington cautioned graduating seniors in her Smith College commencement address on redefining success. 10 Magical Math Puzzles Lay off of the morning math worksheets and try out some of these magical math puzzles that show students how math can be enchanting! 1.

Interpreting the Data: 10 Ways to Teach Math and More Using Infographics From stock prices and unemployment rates to trends in tuition and quality of life, the ability to understand and interpret quantitative data is more important than ever in understanding the world. Over the years we’ve written many posts about teaching with Times infographics, including a 2010 series about using them across the curriculum, and a 2011 lesson called “Data Visualized: More on Teaching With Infographics.” If you like, you can scroll through our entire collection of posts that highlight Times interactives and graphics here. Below, we offer a math-focused list of 10 ways students can learn from and tell stories with the numbers in some recent charts, tables and interactives found in The Times. 1.
An Illustrated Mathematics Glossary - Best of 2015-16 School Year All of this week I am on the road working with teachers in Texas, Kansas, and Arizona. Rather than scrambling to write blog posts at the end of each day, I'm taking this time to feature some of the most popular posts and new tools of the 2015-2016 school year. Math is Fun is a free website that offers math games, puzzles, and tutorials. One of the tutorial resources that they offer is an illustrated mathematics dictionary.
Ce conférencier amène une nouvelle approche pour présenter les problèmes de mathématiques. Au lieu de tout condenser le problème en un seul énoncé où on confond la situation réelle, les éléments mathématiques et la démarche espérée, il tire profit des technologies informatique pour présenter les problèmes en trois étapes distinctes. En premier on présente la situation de la vie courante sans valeur numérique et sans repère mathématique. Les étudiants devraient en venir eux-même à proposer d'insérer des valeurs numérique et des points de repère mathématiques (comme un plan cartésien). Finalement, les questions et la marche à suivre devrait venir d'elles même à la suite de ce processus. La vidéo explique très bien ce qui se passe. by maximeleblanc Feb 28
