Host Mo Rocca shows us the hardware store robot; the incredible patent models from Thomas Edison that show us the beginning of our electronic world; how the USG Corp. is leading the way with grooming the next generation of engineers and mathematicians; the Israeli inventors of a printer that fits in your pocket.

Host Mo Rocca shows us the inventor of a fireproof gel that is helping firefighters save lives; the historic steam engines that are the grandfathers of electricity; a camera that automatically follows you so you're always in frame; and the man who, at 14 years old, invented the email system we use today.
