VISUAL PATHWAYS
When we see the world, we not only see things upside down (because our eye lenses are convex) but also we see DOUBLE (because we have two eyes). How does our brain make these two, upside-down, images into one right-way-up image?
This woman is almost as dreamy as SEXY TYLER (the chemistry guy), and she will explain how our eyes and brain work together to make sense of the world (over a very long 11 minutes I'm sorry not sorry)
The Visual Pathway
If you are finding this too long and you don't find yourself loving this woman as much as I do, then you can try Crash Course but urgh he is so annoying and fast and not at all as tender and loving as Visual Pathway woman.
ISAAC NEWTONS THEORY OF LIGHT

On your worksheet, write down some dot points about how Newton was sort of right, sort of wrong....
