John Davis (c.1550-1605) was a successful explorer during the reign of Elizabeth I. He discovered the Falkland Islands, where his crew killed like 100,000 penguins and the meat spoiled and most of the sailors died of worms, and the Davis Straight, which he named after himself. Basically, he sailed all over the place (maybe even with Raleigh!). Then he invented some sort of quadrant called the Backstaff that was pretty cool. Anyway, he published The Seaman's Secrets, a navigation guide, in 1594.
Tragically, he was killed by Japanese pirates off of Sumatra in 1605. RIP, John Davis. Maybe if you REALLY knew how to navigate properly you would've made it to someplace cool like Atlantis or something.
What is the next necessary thing to be learned?
