We have confused rigour at hand-calculating with rigour for the wider problem-solving subject of maths – the necessary hand mechanics of past moments with the enduring essence of maths.
An example I like to give is to pick up my iPhone, activate its Siri voice recognition and say: "Solve x cubed plus 2x plus one equals zero."
When Carl Sagan spoke of statistics he usually followed the number with an illustration or comparison to make it understandable in context. Numbers alone are meaningless. The question is always what do the numbers mean, and compared to what?
"Today, two megatons is the equivalent of a single thermonuclear bomb—one bomb with the destructive force of the second world war."
Watch the videos for how Sagan communicates complex ideas simply: "a lazy afternoon" and "The Cosmic Calendar"
In our disposable world of stuff, the things that surround us have little value or meaning. Beyond that clutter, are the few pieces that are so intertwined with our personal narratives that they are truly cherished. These items are what we call Objects with Meaning. Join us by posting your own treasured object with the hashtag #OWM.
"Significant Objects, a literary and anthropological experiment devised by Rob Walker and Joshua Glenn, demonstrated that the effect of narrative on any given object’s subjective value can be measured objectively.
The project auctioned off thrift-store objects via eBay; for item descriptions, short stories purpose-written by over 200 contributing writers, including Meg Cabot, William Gibson, Ben Greenman, Sheila Heti, Neil LaBute, Jonathan Lethem, Tom McCarthy, Lydia Millet, Jenny Offill, Bruce Sterling, Scarlett Thomas, and Colson Whitehead, were substituted. The objects, purchased for $1.25 apiece on average, sold for nearly $8,000.00 in total. (Proceeds were distributed to the contributors, and to nonprofit creative writing organizations.) All the project’s stories are archived on this site."
While 3D Animation Movie and TV seems to be a hot trend now a days, but a recent trick to create animated gifs by utilizing depth of field and graphic elements is pushing boundaries among gif creators. The gif creators use a simple but deceptive technique by adding few white lines to the moving images and for a moment it looks like things are popping out of the screen.

If you had to pick the most frustrating part of your Secondary School Maths education, what would it be? For me, it is hands down the trigonometric ratios. You can probably guess how it was taught. The teacher simple wrote SOH CAH TOA on the board, gave some examples and then set us off with work from the textbook.
I remember exactly how I felt at the time. Hold the phone, what are these things sin, cos and tan all about?
"Wordless News is a weekday creative ritual starting at 4:45am. Maria gets up, reads the news, sketches, digitizes, and posts an editorial illustration for a selected headline. "

"Once again, my basic take away is BORING. So, what needs to change? I think I need to revisit the expectations and see what the kids think about the scribing ... I know there are good parts of what we are doing, it just isn’t yet where I want them to be. How can I help them get there? "

Removing playground rules at school eliminated bullying and many student conflicts.
""The great paradox of cotton-woolling children is it's more dangerous in the long-run."
Society's obsession with protecting children ignores the benefits of risk-taking, he said.
Children develop the frontal lobe of their brain when taking risks, meaning they work out consequences. "You can't teach them that. They have to learn risk on their own terms. It doesn't develop by watching TV, they have to get out there.""
It is impossible not to be slightly pleased to see young girls hating themselves a little less. Dove’s “film” has that; but little else worthwhile. It is long. It is preachy. And moreover, its central concept is deeply misguided.
"When Dublin university student Shane Fitzgerald posted a poetic but phoney quote on Wikipedia, he was testing how our globalized, increasingly Internet-dependent media was upholding accuracy and accountability in an age of instant news.
His report card: Wikipedia passed. Journalism flunked.
The sociology major's obituary-friendly quote -- which he added to the Wikipedia page of Maurice Jarre hours after the French composer's death March 28 -- flew straight on to dozens of U.S. blogs and newspaper websites in Britain, Australia and India."
"The back page of the front section on Saturday, February 16, 1991 was four-fifths covered with a Radio Shack ad.
There are 15 electronic gimzo type items on this page, being sold from America's Technology Store. 13 of the 15 you now always have in your pocket."
