Margaret Heffernan: Dare to disagree

Margaret Heffernan: Dare to disagree
Most people instinctively avoid conflict, but as Margaret Heffernan shows us, good disagreement is central to progress. She illustrates (sometimes counterintuitively) how the best partners aren’t echo chambers — and how great research teams, relationships and businesses allow people to deeply disagree. This talk was presented at an official TED conference, and was featured by our editors on the home page.

What makes tattoos permanent? - Claudia Aguirre Further reading to recap what we learned. Urban legend has it that tattooed patients undergoing Magnetic Resonance Imaging (MRI) have experienced the ink being ripped from their skin – Is it true? Even though the presence of metal is common in pigments, there are no documented reports of tattoos being “ripped out” during a routine MRI. But some people do exhibit swelling, itching or burning after getting scanned. There are also reports of pigments causing problems with the MRI results, perhaps because of the metals in the inks (FDA, 2011). While there is no reason to avoid getting an MRI scan, the radiologist or technician should know so appropriate precautions can be taken. Conflict Strategies for Nice People Do you value friendly relations with your colleagues? Are you proud of being a nice person who would never pick a fight? Unfortunately, you might be just as responsible for group dysfunction as your more combative team members.

ARE WE DOOMED? - 300.org The World is facing a climate emergency due to global warming from man-derived greenhouse gas (GHG) pollution. The atmospheric carbon dioxide (CO2) concentration is now 394 parts per million (ppm) and increasing at 2.4 ppm per year. Until recently the atmospheric CO2 concentration was in the range of 180-300 ppm for the last 800,000 years, fluctuations in this range giving rise to successive glacial and inter-glacial periods that imposed selection pressures upon evolving humanity. The average surface temperature is now +0.8C above that in 1900 and this has already been associated with major climate, weather and biological disruptions. Indeed the species extinction rate is now 100-1,000 timers greater than normal. [1].

Just How Small Is an Atom? - Jonathan Bergmann Whether we’re zooming in to the wavelength of a gamma ray or zooming out to the size of a galaxy, it can be difficult to wrap our heads around the big numbers we’re measuring—like nanometers (10-9meters) or gigameters (109). Take a look at these efforts to represent big numbers. What are the strengths of each? How would you represent a large number (like a gigameter)? How to Criticize with Kindness: Philosopher Daniel Dennett on the Four Steps to Arguing Intelligently By Maria Popova / brainpickings.org “Just how charitable are you supposed to be when criticizing the views of an opponent?” “In disputes upon moral or scientific points,” Arthur Martine counseled in his magnificent 1866 guide to the art of conversation, “let your aim be to come at truth, not to conquer your opponent. So you never shall be at a loss in losing the argument, and gaining a new discovery.” Of course, this isn’t what happens most of the time when we argue, both online and off, but especially when we deploy the artillery of our righteousness from behind the comfortable shield of the keyboard.

How to Disagree By Paul Graham / paulgraham.com The web is turning writing into a conversation. Twenty years ago, writers wrote and readers read. The web lets readers respond, and increasingly they do—in comment threads, on forums, and in their own blog posts. Many who respond to something disagree with it. That's to be expected. Printing tricks Printing tricks R2O CMS Water Based Screen Printing Ink Mixing System - SaveDeo.com Description:Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A fill blade or squeegee is moved across the screen stencil, forcing or pumping ink through the mesh openings to wet the substrate during the squeegee stroke. Basically, it is the process of using a mesh-based stencil to apply ink onto a substrate, whether it be t-shirts, posters, stickers, vinyl, wood, or other material.

Video: Can we end pandemics in our lifetime? By tracking social media, it turns out, we can get much better at recognizing pandemics early. Solving epidemics has been the goal of physician Larry Brilliant’s career — and the basis for his 2006 TED Prize wish, which he updated this year in a talk at TED2013, above. His wish called for an “International System for Total Early Disease Detection,” or InSTEDD, a project with the mantra “Early detection, early response” — which included, among other features, tracking stories on the web to watch for patterns that indicate an epidemic is about to break out. After winning the TED Prize, Brilliant founded InSTEDD, a nongovernmental, multilingual, worldwide digital surveillance system that monitors the web, global news and social media for phrases and patterns that may signal a brand-new pandemic. In this update, Brilliant shares new data that shows … it’s working.
