Exploring other dimensions

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.

Da Vinci’s Vitruvian Man of Math

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.

The infinite life of pi

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.

The human and the honeybee

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

The Magic of QR Codes in the Classroom

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.

How Big Is The Ocean?

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.

The Happy Secret to Better Work

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.

An Exercise in Time Perception

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.

Gyotaku: The Ancient Japanese Art of Printing Fish

This is a video about an interesting a piece of Japanese culture – Gyotaku or the art of printing fish.

How did fishermen record their trophy catches before the invention of photography?

In 19th century Japan, fishing boats were equipped with rice paper, sumi-e ink, and brushes in order to create gyoktaku: elaborate rubbings of freshly caught fish. K. Erica Dodge recounts the story of this competitive fishing culture, plus some tips on how to make your very own etchings.

Is Math a Feature of the Universe or a Feature of Human Creation?

This video answers an interesting question :does mathematics exists without humans?

Math is invisible. Unlike physics, chemistry, and biology we can’t see it, smell it, or even directly observe it in the universe. And so that has made a lot of really smart people ask, does it actually even EXIST?!?!

Similar to the tree falling in the forest, there are people who believe that if no person existed to count, math wouldn’t be around . .at ALL!!!! But is this true? Do we live in a mathless universe? Or if math is a real entity that exists, are there formulas and mathematical concepts out there in the universe that are undiscovered? Or is it all fiction? Whew!! So many questions, so many theories… watch the episode and let us know what you think!
