3mankai Birth of the Electric Guitar
Cast in metal, shaped like a pan, electric sound began!
mankai Legend claims Robert Johnson traded his soul to the devil at a crossroads for supernatural guitar skills.

mankai Muddy Waters plugged in his guitar in Chicago, transforming acoustic country blues into a loud, urban force.
Fun Fact

pickup (noun)
An electromagnetic transducer that converts the mechanical vibrations of metal strings into electrical signals. In 1931, George Beauchamp used this technology to invent the first commercially viable electric guitar.

mankai Turns out a knuckleball's wild flight is because it barely spins.
Glossary
seams (noun)
The raised lines of stitching that hold a baseball's leather cover together. These ridges disrupt the surrounding airflow to create tiny pockets of turbulent air, which reduces drag and helps the ball fly much farther. Without them, your favorite pitcher's curveball wouldn't curve, and home runs would be incredibly hard to hit!

Fun Fact
Vibrant Red Seams: Dating back to the 19th century, these traditional stitches aren't just for looks. They create aerodynamic drag, allowing pitchers to throw curving pitches.
mankai Physics of a Curveball
With a rapid spin, The Magnus effect takes hold, Air pressure shifts, Watch the curve unfold!

mankai The 108 red stitches on a baseball are designed to control airflow.
Fun Fact
Knuckleball velocity: A knuckleball travels at only 60 to 70 miles per hour, but its unpredictable movement makes it incredibly difficult to hit.

mankai A knuckleball barely spins, causing unpredictable air currents to push it randomly.
Glossary
magnus effect (noun)
The force exerted on a rapidly spinning cylinder or sphere moving through a fluid, causing it to curve away from its straight path. In 1959, physicist Lyman Briggs used wind tunnels to prove this phenomenon causes breaking pitches to curve.
