The combine harvester. In the world before the combine harvester the Second Great Awakening was happening from 1790 to 1820. Presbyterians couldn’t supply pastors fast enough and Freemasons thought to have murdered a “rat” in 1826, this spark widespread outrage against freemasons. Hiram Moore born in New Hampshire 1801, had a neighbor named Hascall who fled to a Freemasonry had a farm with no workers to reap the harvest. Hascall told Moore about his wife’s dream to have a machine that would reap the fields of wheat, so Moore began to experiment and then in 1834 he invented the combine harvester.

The solar compass. In the world before the solar compass, Rome had professional surveyors and new instruments appeared in the 1500s, Theodolite appeared in 1785, and the US created public surveying department in 1785. William Austin Burt born in 1792, developed scientific interests nautical navigation, and he wanted to help mankind navigate. He invented several inventions and became a surveyor for the US government, then he invented the solar compass to solve a magnetic interference in 1835. The solar compass didn’t have to rely on earth’s magnetic field and had complex instruments with movable parts to determine position.

The propeller. Before the propeller people used paddles to row with sails to turn in a certain direction, it took Columbus 2 weeks to get to the Americas. Archimedes invented the versatile screw around 250 BC. Da Vinci imagined screw in a helicopter and others began experimenting with using it in boats. Francis Pettit Smith born in England 1808, who became a farming apprentice, was fascinated with boats as a child and he became interested on how boats were powered so he began experimenting and then in 1835 he invented the screw propeller.

The mechanical computer. In the world before the mechanical computer Egyptians and Greeks used the abacus to do math and the Romans used a more complex abacus. Blaise Pascal invented the mechanical Calculator in 1642, Leibniz invented the wheel to improve the Calculator in 1673. The Jacquard Loom was invented in 1802 Charles Babbage born in London 1791, became self taught in math, books of logarithms and data tables were vital in many fields, they contained errors, and Babbage wanted to fix that, And then designed his “analytical Engine” in 1835.
