January 7 - Optical Illusions

Checker Shadow Illusion

- Even after reading the explanation, it is hard to believe that this is true. I just can’t believe that it is. I have no idea how it is true but the picture explanation that they gave proves that it is true, even though it doesn’t appear to be.  They talked about the shadow from the cylinder that is affecting the light that is shinning on the square. Also, the surrounding squares affect how we see the square. Because darker squares are surrounding B, it appears to be lighter. The squares surrounding A are all lighter so A appears to be darker. 

- More illusions

            - Many of these illusions were easier to believe then the checkerboard illusion. The white’s illusion was one that was tricky. It is so crazy to see how much our eyes change the color of the gray because of the surrounding colors. My favorite is the vasarely illusion. It is interesting to see how the squares stacked on top of each other cause the white to appear on the pyramid. 

  

Curve ball Illusion

- This illusion appears as if the ball is dropping straight down, but if you look over at the blue dot on the side the ball appears to be dropping at a angle. It is kind cool to see how because the colors in the ball is spinning; it appears as if the ball is dropping at angle when not directly looking at it.  The same thing goes for the reversal illusion.  The circle is spinning counter clockwise so when you look right at the circle you see that movement, but because the colors is the ball are moving in the opposite direction when you look away, the circle appears to be moving clockwise. 

- Other illusions

            - The first place illusion with the slopes is crazy.  From the angle of the camera it does truly look like the balls are moving up the ramp, but if you look closely you can see that they are not really going up.  Then when they switched the camera angle, you were able to see that the slopes were actually going down. 

Grey Circles

            - For this illusion, I had an idea of how it was trying to trick our eyes. The inner circle is going to look smaller then what it really is because it is surrounded by larger circles and all the numbered circles are going to look larger then what they are because they are surrounded by smaller circles. With this in mind, I still guessed wrong on what circle was the same size as the middle one. I guessed that 6 or 8 were the same size as the middle one when the correct answer was number 3. At first look it appears that number 3 is larger then the middle one, but if you look really closely you can see that they are the same size. 

Yellow dots

            - I thought that the yellow dots one was really cook. It was crazy to see the yellow dots disappear. I kept trying to get the all to go away, but the most I could get at one time was 2.

Color blindness

            - Looking at the different examples of color blindness and seeing what each of them see really makes you appreciate your ability to see all the different colors. It seems like they are able to maybe see one or two colors and then just different shades of that makes up the rest of the colors. It would be very frustrating for me to not be able to see all the many different colors that are in creation.
