Industrial Revolution: New things being invented, things already invented becoming better, lots of manufacturing.
James Watt was an inventor and mechanical engineer. He was a big chunk of the Industrial Revolution. He took the original steam engine from Thomas Newcomen and improved upon the use and build of it with his own steam engine. Doing so was crucial during the Industrial Revolution. It gave way to being able to transport goods and people cross country. He was apart of the whole "making things better that are already invented.".
