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 Facebook’s newest teen engineer supported his family with apps until cashing in There’s nothing that highlights the fact that Silicon Valley is the new Wall Street, gold rush, colonial settlement — insert your American Dream rags-to-riches historical moniker here — quite like the story of 18-year-old Miami resident Michael Sayman. This week, Facebook hired Sayman as one of its youngest full-time engineers in history. He wouldn’t tell me his salary, but admitted his friends are already pressuring him to “buy a Tesla,” which he won’t do because he’d “rather save the money.” Before you go throw up at the idea of a teenager buying himself a Tesla off tech riches, there’s few people who deserve that luxury quite as much as this kid.
Repair businesses provide antidote to throwaway culture The hall of a primary school in Brooklyn is unusually busy for a Saturday morning. This is a "pop-up repair" event, and it is drawing in the crowds. Parents and children from around the neighbourhood have brought in their broken things to be fixed by menders, each with their own area of expertise. At different tables, repairers fix jewellery, electronics and furniture among many other things. This is also an opportunity to teach kids repair skills, and a group of boys is hammering away in the corner. 12 Must-See TED Talks for Purposeful Women - Let Why Lead When my husband first started cueing TED talks for us, I’d try to convince him to go for Modern Family instead.

5 Reasons To Write A Letter To Your Future Self In March, I turned twenty-five years old, and on that most dreaded day I received a letter from my twelve year-old-self. At twelve, I distinctly remember listening to Britney Spears’ “Ooops I did it Again,” consuming Fruit by the Foot, surviving Y2K, and wearing checkered school jumpers that came down to my knees. It was that magical time right before pimples started growing uncontrollably and watching Saturday morning cartoons was still acceptable. Oh how much has changed since those simple times. Reading my letter evoked a lot of emotions in the span of two minutes. It was hilarious that I questioned my own ability to achieve higher education, or better yet, to even have higher education as my main concern at the age of twelve.
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.
