Math Links for Week Ending Dec 28, 2012

Possibly one of the best TED talks on data visualization. David McCandless (who calls himself a data journalist) shows simple representations of data that convey a very definite message. None of the vagueness of normal graphs. Check out the stuff on his website too: http://www.davidmccandless.com/

Visual Patterns is a new website launched by Fawn Nguyen (check her own post about it here). The site is for helping students develop algebraic thinking through visual patterns. This should be perfect for the intro to linear growing patterns or linear relations, even non linear growing patterns

Another TED talk, this time about the power of an algorithm. I like the bit about an algorithm that lead to a trench to be dug from NY to Chicago. All to save 3 milliseconds on a transaction. The first graph he shows is also pretty cool.

Here is a YouTube video of Keith Devlin (NPR's Math Guy) having a debate about whether math is more of an art or a science. Its long though.

  1. The process of creating software that runs on a mobile device is referred to as mobile application development (smartphones, tables, wearable). However, app development is more than just writing code for a native, HTML5, or hybrid app. It is concerned with the strategic process of conceiving, designing, developing, and releasing a successful mobile product. also visit here content creation services

  3. I highly relate to you in finding this ted talk as one of the best, I am a student and find ted talks as a great resource and can surely be used as a solution to many academic and life problems, you wont believe how much help and motivation ted talks provided me when I needed to do my GED exam. I was feeling helpless and had no motivation to do my exam untill I found this channel and things got completely changed.

  4. This week, I stumbled upon a fantastic TED talk by David McCandless, who's a pro at turning complicated data into clear and powerful visuals. He's not just a data journalist but a magician of sorts with graphs. His talk shows how simple pictures can tell big stories without any confusion. You should also check out his website for more cool stuff. Even though I had to take my online examt on my mind, diving into his ideas could really help me see numbers in a whole new light.
