Without a human eye and brain there is no color.

Images and Links


String Crossing
Seeing versus feeling. Look at one string. What do you see?


Finding Rays
Observe a small bright light, notice the rays. Where are they?

gray step

Gray Step
Learn how the eye and brain emphasize change, for example edges.

Size distance illusion

moonrise sierra

Moon Illusion

Measure the moon's angular size as it rises

Size Constancy

size distance

Size Constancy

Perceived size depends upon more than the size of an image on the retina.

Acoustic Illusions

find the highest note

Find the highest note Acoustic illusion. Museum exhibit available as an Ipad app. Sound Uncovered

Touch Illusions

line up by hand temp

Feel the Temperature

People line up by hand temperature. Then people from the ends of the line shake hands with everyone else.
Verify the result with a thermal camera.

Model of a nerve

domino model nerve

Domino Model of a Nerve, Human Body Book

Explore how a signal propagates only after exceeding a threshold, and how the speed of propagation and signal amplitude is independent of the trigger signal.

Teaching in a 3D virtual world
quantum lecture

Quantum physics class in Second Life 50 students: slides, videos, 3D interactive models, voice , text for whole class, individual private chat. Assistants!

Twinkling Suppressor

twinkling suppressor

When twinkling dots rotate the perception of twinkling is reduced.
