Blackbeard the Wave Glider

To our ears, the sound of being underwater is all the same muffled tone. But to East Carolina University scientists, the noise carries all sorts of information about the ocean. Watch as researchers use their acoustic wave glider named Blackbeard to study underwater noise, acoustically tagged fish and environmental conditions in the ocean.

Animals on the Grid

Animals in Africa face challenges from dwindling habitats and climate, but most dangerous of all can be farmers or poachers who can kill threatened species for protection and profit. Watch how researchers at the North Carolina Zoo are using radio and satellite tracking to follow and protect animals in Africa and in our own backyard.

Mechatronics

Mechatronics blends principles of design and engineering to create the most innovative, economical, appropriate and elegant solutions to engineering problems. Watch engineers and students from NC State University and UNC Asheville put mechatronics into action.

Rock and Roll Energy

All music is a study in physics; from the vibration in a singer's vocal cords, to the resonance of vibrating air in a violin, to the electrical signals from a computer that become a hip-hop beat. The electric guitar takes the cake, converting one type of energy into another, amplifying an electrical signal, and converting the energy back to sound. Learn how a simple strum turns into a booming electric guitar sound in the module below.
