Beau Lotto TED Talk

In Class

We watched a TED Talk video by Beau Lotto about optical illusions. The main purpose of the TED Talk was  about the difference of our perception of the world and how the world really is. Beau Lotto used a lot of colors to show how they can affect our perceive the world. A quote that he used, "We have no direct access to our physical world other than our sense". Light allows us to see the world, but there are many factors that affect our vision, such as the color of the object, the color of the light that reflects the object, the color of the space between our eyes and the object, and etc. 

I think an issue that Beau Lotto is trying to point out that we will never know how or what the physical world really is. Maybe every individual on this earth has their own different perception of the physical world. This then makes me wonder, if physical things are actually not what they seem and are perceived differently by everyone, then do we perceive intangible things, such as emotions differently too? If we cannot be sure of what we see is the same, then there might be a flaw in our standards. For example, Ariel and Betty are looking at a color. Assuming that both of them don't know the name of the color, but Ariel sees the color green and Betty sees blue. Then, they were taught that the name of the color was sea green. As a result, every time Ariel sees the color green and Betty the color blue, they call it sea green. Then again, I wonder, does the difference really matter?
