Total Isolation Brainwashing

2012-02-27T03:44:00.000-08:00

The 48 hours of total isolation is over for our three volunteers. Emerging from the dark and silence cells they are asked to repeat the series of tests undertaken before they went into total isolation. The results are startling with even the most basic of tasks proving extremely difficult.

The Periodic Table Table

2012-02-24T08:51:00.001-08:00

Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and thousands of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table." Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones.

Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories. Come see for yourself in the latest episode of Bytesize Science.

Physics and Biking

2012-02-06T04:35:00.001-08:00

Maxwell von Stein, a 22-year-old graduate of The Cooper Union, built bicycle that uses a flywheel to store energy. Instead of braking, Max can transfer energy from the wheel to the flywheel, which spins between the crossbars. The flywheel stores the kinetic energy until Max wants a boost, then he can transfer the energy back to the wheel using a shifter on the handlebars.

Communication between cerebral hemispheres

2012-01-27T23:24:00.000-08:00

To reduce the severity of his seizures, Joe had the bridge between his left and right cerebral hemisphers (the corpus callosum) severed. As a result, his left and right brains no longer communicate through that pathway. Here's what happens as a result:

Microwaves Ruin Everything

Ever wonder what would happen if you put a watermelon in the microwave? Or a lightbulb? Or a champagne bottle? We slowed it down for you so you wouldn't miss a thing. Real explosions...just not in real time. And yep, it's true. Microwaves ruin EVERYTHING.

A Da Vinci surgical robot was on show at an open event to raise awareness of men's cancers for Blue September at Southmead Hospital on September 28 2011. Members of the public, former patients, prospective patients, staff and GPs all attended the event to try their hand at robotic surgery. Here, urology fellow Ramesh Thurairaja peels a grape.

QBO Robot in front of a mirror

2011-12-07T00:42:00.001-08:00

This video corresponds to a small experiment in which we put Qbo in front of the mirror to see if he can learn to recognize himself. For that, we used the "Object Recognition" mode and the "Face Recognition" mode. Qbo, using its stereoscopic vision, selects his image in the mirror and, with the help of one of the engineers, learns how to recognize himself. This quite simple experiment touches interesting psychological aspects of self-consciousness, whose complexity can be proved by the fact I already mentioned of the few species that can recognize themselves in front of the mirror. In this first version, a human guide presents Qbo to himself, but we are working so as the robot could present and self-recognize himself autonomously when found in front of the mirror.
