My mind is reeling with replies at the moment. But I'll be sensible.
A screw (stop sniggering at the back) turns rotational movement in to horizontal movement. You can use the principle to lift water or grain (Archimedes screw), join things together (much stronger than a nail), and make very accurate instruments. A screw advace on a lathe was used to make early clocks and scientific instruments.

we are in this condition as a results of monetary corporation that offer funds to the authorities. The monetary corporation of britain became formed in 1694 by William Paterson, his quote "The monetary corporation hath earnings of pastime on all moneys which it creates out of no longer some thing". They write the money that we use yet in addition they upload pastime to it (pastime cost). The united states will continually be in debt because the debts is continually above the quantity of funds interior the gadget because of the further pastime cost. In u . s . a . of america they have the Federal Reserve which became formed on the very similar concepts interior the early 1900's. Any united states who's funds grant is created by those skill will continually be in debt and could discover itself having to borrow further and extra to pay the debt it owes till it really is going to certainly collapses. in case you want to be sure about the rules that are determined for in this international then look into The Council on overseas relatives or The Trilateral fee. the objective is for the economies to finally fall down and for there to be a sparkling international Order. the human beings who've created this funds gadget do not ignore that it won't be able to live to inform the tale indefinitely and performance deliberate ahead. Usury.

Screws were actually the first water pumps...By putting a big screw in water, and spinning it (without pushing it down), water moves up the screw.
They also help us to dig wells, for water, and for oil.

holding things together plus the people that make them and sell them all have jobs because things hold tighter with screws rather than nails
