.Reflection This week in humanities we read the first two chapters of Light by Bruce Watson. This book was very informative about the science and theories of light throughout the centuries. After we read these chapters we had a seminars talking about our thoughts about what we thought and we tried to find the thesis and most important parts of the text. I really liked this book because it talked about light through the views of a diversity of people like astronomers, mathematicians and artists. In chemistry we watched a show called Exploring the Cosmos which was a show with Neil Degrasse Tyson talking about light and color and how color is created. This video talked about the history of how we know what we know about light now. Humanities This week in Humanities we wrote and edited a short essay about how the work of scientists, artists and philosophers cause people do wonder and be curious.

What is the Chemistry of epoxy and polymerization? The resin is a polymerization of carbon and acetyl which takes the form of strands. When the hardener is mixed with the resin the hardener acts as a catalyst. A catalyst is a group of molecules that causes a reaction to happen without affecting the reaction with any of its chemical structure. In this case, the hardener causes the polymer to link with each other causing it to harden together. This is how our epoxy is created. When we lightly heat the epoxy to bring the bubbles to the surface, we are partially undoing this bond by heating the bonded molecules up, thus unbinding the linkage letting the air pockets rise to the surface. What can we learn from light? What information is in light? After watching Exploring the Cosmos I have learned many thing about light that I never would have thought that it could do. Light can tell us how far away an object is because things that are farther away from us are more blue than objects that are closer to us that are more red. This is because blue light is light waves that have long wave lengths while red light is light waves that are compressed which means that the wavelengths are smaller then that of the color blue. This is how science has discovered that the universe is expanding, because everything in the universe is slowly getting bluer and bluer. Light can also tell us what something is made up of. Certain objects, depending on how much energy they have, can absorb certain colors and not others. The colors that can not be absorbed are the ones that we see because instead of being absorbed it is reflected. This is how Scientist can tell what things are made of millions of light years away from us. Main Project This week I finished processing my landscape photo. Hopefully next week it will be printed and coated with epoxy.
