Optical Illusion That Tricks Your Brain Into Time Travel @caltech
How does the brain make sense of all the information we’re bombarded with every second of every day?
It’s a complicated question, but researchers have invented two new illusions that give us some clues – one optical and one auditory. And they both trick the brain into travelling back in time to fill in gaps it thinks it’s missed.
This is technically known as postdiction, where a stimulus can have an affect on what we think we saw or heard in the past – as opposed to prediction, which works in the other direction, forwards through time.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
