Interest in Materials

Note

I've been informed that occassionally trends.google.com refuses connection and thus the embedded graphs aren't being displayed. Not sure what the best option is here other than static versions, however, if its not showing for you I would just go to trends.google.com and manually use the terms, Materials Science, Materials Engineering, etc.

I was curious whether or not there has been an increase in the number of people interested in materials science and engineering. My initial hypothesis was "I have a strong belief that people are more interested given that most advances in technology will require new materials". With that said I started to look at Google trends to see if I could use any data they collect and sure enough they let you look at search trends. So what is the search trend over the last 20 years for materials science and engineering? Below are the results:

Turn's out my hypothesis, based on Google trends data, is not true. More specifically, it seems the keywords I used with google trends aren't trending up. You actually see a trend down or constant. We can also look at how the interest is distributed across different countries.

I'm a bit curious why it was higher in 2004-2005 and then dropped off and has been constant since then.
