The brain cannot do physics!
Why is it nevertheless often correct in its assessment of speed?
Our eyes move more often than our heart beats. This means that the environment is also constantly moving across our retina. Nevertheless, we perceive our environment in a stable way, because our perception is actively constructed by the brain. How does the brain manage this? Targeted laboratory experiments can reveal systematic errors in the interaction of eye movements and perception, which help us to better understand how the brain works to construct our perception of the environment from physical stimuli.
