Barbara Block and her Tag A Giant project are well known to folks at Duke Marine Lab, where I work.  It was fantastic to see her talk and I encourage you to take 20 minutes to see how technology is shaping our view of the oceans and [finally] contributing to our knowledge.  Perhaps some day in the near future we will put to rest the fact that “we know more about the surface of Mars, then about our very own oceans”.  Thanks to Barbara and other ocean scientists.

This is a very interesting TED talk on an ambitious project to better understand the brain.  The scope of the project of mapping the “connectome” –the sum of the connections between neurons and synapses, etc in the brain — is enormous and the potential for understanding the brain is astounding.  Although I would tend to say I am even more than my connectome from a spiritual and Christian worldview, I think you should watch the talk, it is well worth a few minutes of your day.

I really enjoy TED talks — Even if I run into a topic or speaker with which/whom I disagree, the talks are always intriguing and thought provoking.  I just listened/watched David McCandless on Data Visualization and just want to be able to do the graphics on my own.  Mathematica is one tool I can use and I sure want to explore data visualization further — especially as it relates to understanding physics and mathematics.

Wolfram|Alpha vs  Google ?

No –> complementary tools

Wolfram|Alpha is a computational engine

Sometimes tech journalists will call a new service a Google killer even when it’s not a search engine. That’s the case with Wolfram|Alpha. It’s easy to confuse Wolfram|Alpha with a search engine. It has a field into which you type a query and it searches its database for answers. But that’s where the similarity ends.

Search engines provide users links to Web sites that presumably hold information the user wants. Wolfram|Alpha consults an enormous database to bring data directly to the user. You won’t receive a list of links when you execute a query on Wolfram|Alpha. Instead, you’ll be greeted with charts and graphs populated with data related to the keywords you entered.

This makes Wolfram|Alpha a very powerful research tool. Wolfram|Alpha employees vet all the information included in the database. They pull data from established and accepted resources. You can use Wolfram|Alpha to compare two subjects within the same category. Want to see if a Big Mac is healthier than a Whopper? Use Wolfram|Alpha to compare the nutritional information.

Because Wolfram|Alpha pulls back data rather than links, it’s not in direct competition with Google. You should use Wolfram|Alpha if you need to know information about a specific concept. You should use Google if you want to read the latest news on the subject, find a product review or just browse.

Geek Time

I glanced at this while students were taking a physics exam and want to really understand it.  So far I have only scanned the slides — anyone out there have thoughts about implementation and application to “my personal data” — Wanting to share — but wondering who the users are and ..well just wondering right now.

Customized Search Engines

Learning is ongoing for me and the pace seems to quicken daily, especially with regards to technology and coding.  I have just begun exploring customized search engines and wanted to share this reference video:
