This is a video from TedEd about the lack of definition of comedy.
What makes us giggle and guffaw?
The inability to define comedy is its very appeal; it is defined by its defiance of definition. Addison Anderson riffs on the philosophy of Henri Bergson and Aristotle to elucidate how a definition draws borders while comedy breaks them down.
This is a very interesting video about the world of dimensions.
Imagine a two-dimensional world — you, your friends, everything is 2D. In his 1884 novella, Edwin Abbott invented this world and called it Flatland.
Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.
An interesting view into Da Vinci’s Vitruvian man.
What’s so special about Leonard da Vinci’s Vitruvian Man? With arms outstretched, the man fills the irreconcilable spaces of a circle and a square — symbolizing the Renaissance-era belief in the mutable nature of humankind.
James Earle explains the geometric, religious and philosophical significance of this deceptively simple drawing.
This is a video about the number PI.
The ratio of a circle’s circumference to its diameter is always the same: 3.14159… and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we’ll never figure out its exact value no matter how close we seem to get.
Reynaldo Lopes explains pi’s vast applications to the study of music, financial models, and even the density of the universe.
This is an interesting parallel from TedEd about humans and honeybees.
Both honeybees and humans originated in East Africa, and the connection between us has survived the ages. Some of your favorite delicacies — coffee, chocolate, mangoes — have the honeybee to thank for their hard work of pollination. Dino Martins encourages us to remember how much we owe to these magnificent insects
Can we use QR Codes for learning purposes ?
Teaching is both a science and an art, and many teachers around the world spend endless hours perfecting their professional practice. At TEDActive 2013, a few teachers from the United States offer some tricks of the trade they’ve learned (and continue to hone) along the way.
This is an interesting video about the technology of “the great firewall of China”.
Michael Anti (aka Jing Zhao) has been blogging from China for 12 years. Despite the control the central government has over the Internet — “All the servers are in Beijing” — he says that hundreds of millions of microbloggers are in fact creating the first national public sphere in the country’s history, and shifting the balance of power in unexpected ways.
This is a video about some interesting information about our oceans.
While the Earth’s oceans are known as five separate entities, there is really only one ocean. So, how big is it?
As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth’s grandest geological features. Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us.
Is there a secret to being happy?
We believe that we should work to be happy, but could that be backwards?
In this fast-moving and entertaining talk, psychologist Shawn Achor argues that actually happiness inspires productivity.
This is an interesting video about time perception.
Why is that some experiences feel like they last forever, while others fly by? We tend to miscalculate the time it takes to engage in novel activities due to the influence of memories. Matt Danzico explains why your childhood feels like it lasted forever and why that beach vacation seemed like two months rather than two weeks.
