Some Links You Wanted to Share with the Rest

• Martín came across this very interesting video about wi-tricity (or wireless electricity). Some classes ago, I remember one group explained this technology to me. So here you have an explanation from an expert. It's really interesting and the technology sounds promising.

• Ivana sent me this link where you have tons of information and links about science. You can spend hours reading really amazing things.

I know you don't have much time, but whenever you have some minutes to spare, try to click on the links and visit these pages your classmates have shared, cause I'm sure if they found them interesting, so will you!

The sky is the limit...

I was surfing the net today, looking for some interesting article to post here, and I came across this new development Xerox patented a few days ago:

Xerox Develops Silver Ink for Cheap Printable Electronics
(PhysOrg.com) -- Xerox has developed an ink which can be used to print circuits onto plastics, films, and textiles. Although circuits printed on flexible materials aren't new, Xerox's method may be cheap and easy enough to open the doors to many new possibilities for flexible electronics.

I believe the possibilities are huge. My daughter is running a fever right now and she hates it when I use the thermometer to messure her temperature, so I was wondering: What if I had a T-shirt with a built-in thermometer? That would be great!
What other applications can you think about?
And BTW, for all of you chemical engineers, here is a short video where they explain how they are able to melt silver at a very low temperature.

Here is the link to the article posted by Xerox, in case you're interested in reading it from the source.

Business climate

Here is the definition for business climate

And here is a short article explaining the concept.

Reading, reading, reading

I've already posted a link to practice listening. Today, surfing the net, I came across this website with tons of movie scripts. I believe it's a great opportunity to practice every day language and they also include a lot of descriptions. Many of the links open a pdf file with the complete script. Others, link you to another link where you'll find the script. Of course, scripts are 100 pages on average. You don't need to read the complete script, but just a quick look can help you learn some new vocabulary and useful phrases. Hope you like them!

And BTW, remember last class we talked about the movie Envy? Look what I found :)
