Fun with Chemistry

Good afternoon everyone! On this day in 1884, the first long distance phone line between Boston and New York was inaugurated using Alexander Graham Bell's recently invented telephone. This was the first line to use copper wiring instead of galvanized iron; copper has a greater attenuation of signal, creating a stronger connection. The wires carry electrical currents from one point to the next, which is just electrons moving through the wire. While today's cell phones use a different form of signal, Bell's breakthrough (and use of chemistry!) paved the way for the global connection we share today!
