Jethro Tull invented the seed drill (in 1701), the horse-drawn hoe, and an improved plough. Tull was educated at Oxford, England where studied law, he later studied agriculture during his travels across Europe. Jethro Tull inherited land in the southern part of England where he put into practice his study of agriculture. \nHis seed drill would sow seed in uniform rows and cover up the seed in the rows. Up to that point, sowing seeds was done by hand by scattering seeds on the ground. Tull considered this method wasteful since many seeds did not take root. The first prototype seed drill was built from the foot pedals of Jethro Tull's local church organ. \n\nJethro Tull was part of a group of farmers who founded the Norfolk system, an early attempt to apply science to farming. In 1731, Jethro Tull published "The New Horse Houghing Husbandry: or, an Essay on the Principles of Tillage and Vegetation".

You can also try Olander.  \n\nhttp://www.olander.com\n\nWhere ever you decide, you'll probably have to buy $5 - $10 worth.  They don't sell screws individually.  \n\nMcMaster-Carr is also very good.\n\nEDIT: I know olander's site is tough to navigate and the descriptions aren't so good.  Calling is a lot easier sometimes.  \n\nI took a look and found a stainless steel screw there that might be what you're looking for: 3F37PFMS.  \n\nYou should call them to see if this is the right one though.

Clock: inventor: In c.3500 BC, the gnomon—the first clock—is invented, probably in Egypt. It consists of a vertical stick or pillar inserted in the ground, the length of its shadow giving an idea of the time.

I think it was Rene Descartes who said "I think so therefore I am."  Whatta guy, not only a philosopher, but he developed the Cartesian coordinate system--y'know, used for graphing equations and functions using the x- and y-axes.
