I found this article very interesting. One thing I found interesting was the fact that the rubber underneath the turf is made of grinded up tires. I also found it fascinating to see that the rubber used in the track is not made from tires, but is actually virgin rubber. Another thing that I thought was interesting to see how hot the turf can get on a sunny day. This article is relevant to our class because it deals with the polymers and the chemistry aspect of an artificial track and turf.

I read the article on tidal energy and the advances in tidal technology as an alternative energy resource. I found this article very interesting because I did not know that tidal energy was such a predictable energy resource. I learned that the tides are more predictable than solar or even wind energy. It was very interesting to see that there are tidal turbines in the East River in New York. I did not know that the United States actually utilized tidal energy in its body of water. I also thought it was interesting to see that there are many scientist working to develop stronger and more efficient turbines that will help our world be more energy efficient.

I found this article on Einstein and his work very interesting. One thing that I found interesting was the example of the clock and the rocket ship. I think that is really cool to know that if this experiment was actually to be done that the clock would seem as though it is stuck at the time that you left. I also find it very interesting to see that no one actually gets the precise time. Since there is a small time where light needs to reach our eyes, humans will never actually experience the actual time. I also thought the beginning was very interesting when they took us back to 1905 and described all of the differences in our worlds. This article is very relevant to our class because it deals with light and the atomic structure. We have already studied the atomic structure and now we are studying light and waves.

**Periodic Table**
I found this article very interesting, and I never knew that there were so many alternatives to the current periodic table. I believe that some of these alternatives have some potential to become a better table, but others are confusing and hard to follow. I find it very interesting to see that so many scientists are working for their whole careers to create a better and more useful periodic table. This article is also very pertinent to our current studies. We are currently studying the periodic table and its trends. Some of these proposed changes may change some of the trends seen on the current periodic table. I think that some of new periodic tables have some potential to be the periodic tables of the future, however, others seem confusing and unhelpful.
