This week's link is a testament the power of crowdsourcing on the Internet. Nearly twenty years ago, an elderly woman who had been rendered non-communicative by a fast-moving cancer scribbled out patterns of letters onto dozens of note cards. Her granddaughters believed that their grandmother had left them a code, and though they attempted to decode the seemingly random patterns of letters for months, the girls were unable to find a solution. One of these granddaughters recently posted images of the cards on the website Ask Metafilter, and within a few minutes, site users had partially cracked the code. Read more here.

Consider the application of this fascinating story to past SAT prompts such as:

Has today's abundance of information only made it more difficult to understand the world around us?
Is the most important purpose of technology different from what it was in the past?
Have modern advancements truly improved the quality of people's lives?

Good luck to those of you taking the SAT today! Check back here next week for a new link.
