Periodic Table

When I was reading the article on The Many Looks of the Periodic Table something I found interesting was the triads on the periodic table. I never knew of the existence of these triads on the periodic table. The one thing I don’t agree with this theory is that Scerri thought about moving hydrogen above fluorine and chlorine to form another triad. Another thing I found interesting about the article was the variations of the periodic table. My favorite version was the galaxy version. It was a very out there method of arranging the elements. I would have to say that I like the original periodic table the best out of all of them.

Polymers in the Field

I was very surprised that the Mondo track surface was created by "virgin" rubber. I didn't know they were not created from shredded tires like the rubber granules in the turf. The thing that I learned from the article was the the football field had a 0.5 percent slope to account for water drainage when it rained. I always noticed there was a slight slope but I didn't know how much.

Alternative Energy Sources

I read the article, " Is the Hydrogen Car the Car of Tomorrow." Something I found interesting about the article was that the hydrogen car they mentioned could cost as much as $200,000. Personally for that amount of money I would not buy the car despite the fact that it could get 70 miles to gallon. Also with only a few filling stations across the nation it doesn’t benefit anybody who doesn’t live in those specific areas. What I found interesting was that one of the filling stations was in Allentown, Pa. The reason I found this interesting is because my grandparents live in Allentown and I never knew there was a hydrogen filling station there.

Einstein

In the article about the discoveries that Einstein made I found it interesting that if you were in a rocket traveling at the speed of light and looking at a clock in a fixed position that time would appear to stop. This makes sense when I think about it because the light will never catch you if you are moving at the same speed. Something new that I learned from the article was that a student in the front of the classroom will technically see a different time than a student in the back due to the time it takes the light to travel. Even though the difference is negligible it is still a bit out there. The article relates to what we are doing in class because it talks about the minimum threshold of intensity of the light and some of the homework problems we do involve calculating that energy.
