Reality?

Part 1 of this eight-part series of shorts introduces the world of the visual scientist. Beyond boggling your mind, Prof. Arthur Shapiro explains how and why you see what you see -- and what part of what you see is actually "real", as opposed to how your mind fills in the blanks.

Motion

In part 3, Prof. Shapiro shows us that the brain is challenged to process some stimuli from the eyes and sometimes "guesses" what you are seeing. Join him as he takes us through visual perception challenges like the "Curveball Illusion". Has he thrown you for a loop yet?

The Classics

Artists like M.C. Escher played with our visual perception in their art. In this 4th installment of the series, Prof. Arthur Shapiro returns to the classic visual illusions that show us that what we see is not exactly in plain sight.

Grouping

Prof. Shapiro offers us more challenging questions about the way we see as he shows us how light that hits the retina is interpreted by the brain. Can you see something before you know what you are looking at? Check out these illusions and find out!

Ambiguous Images

Ambiguous Images

Professor Shapiro shows us how some images can prompt two, or even three, equally valid interpretations. Rather than settling on one interpretation, our brains tend to switch among all of them – leading to some baffling and astonishing visual experiences.

Impossible Objects

Impossible Objects

Professor Shapiro shows us a range of objects that seem simple and unremarkable at first glance, but which on closer examination simply cannot be constructed in reality – or are not at all what they seem.

Perspective Games

Perspective Games

Professor Shapiro reaches back into history to show that artists, architects and mathematicians have also employed visual “tricks” to baffle and entertain us by manipulating perspective and challenging our ideas of what is real and what is fake.

Freedom of Choice

Freedom of Choice

We may value having Freedom of Choice, but are we actually happier when we have limited choices...or even no choice at all? Do we truly have control over our decisions, or are they really predetermined by other forces? My fellow YouTubers and I have our minds read by a “box” that reveals who - or what - is really calling the shots.

Mind Reading

In this episode I visit a researcher who is studying memory by using machine learning and neuroimaging to detect and predict people's brain states. I also travel to Japan to meet with a team working on ways to record the content of peoples’ dreams.

The Stilwell Brain

The Stilwell Brain

There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!

The moon illusion

The moon illusion

Have you noticed how the full moon looks bigger on the horizon than high overhead? Actually, the two images are exactly the same size -- so why do we perceive them differently? Scientists aren't sure, but there are plenty of intriguing theories. Andrew Vanden Heuvel unravels the details of focus, distance and proportion that contribute to this mystifying optical illusion.
