But, they should have rolled a few years back. -- John Have a Super Christmas and a Spectacular New Year! yes, I feel they should, but do you think they will? No. The NYT is a liberal rag. Liberals, from my experience, could care less about the truth. Remember, morals are a religious, not a legal, concept. Therefore integrity is not a trait valued by liberals or secular progressives. Actually, you could figure that out right here in the NG. ;) Some of the most amoral creeps in time have been Popes. It damn sure isn't a religous concept. If you're interested do some homework. A religious concept isn't necessarily followed by 'religious' people. Look at Krause. He claims to be 'religious', but surely his faith doesn't promote lying and name-calling. Maybe it does. No. Judaism doesn't condone such behavior. -- John That's funny. You don't look Jewish. What does Jewish look like Krousie? You nitwits need to get out in the world a litlle more. "Funny, you don't look Jewish" is a VERY old and well worn comeback line. It pokes fun at the notion of stereotypes. Frank Zappa helped popularize it for younger generations. Obviously, the level of "cultural literacy" among the right-wing retards like Florida Jim here is...low.- Hide quoted text - - Show quoted text - You should post a picture of your Yale degree, that would really impress people.

Bushnell isn't even mentioned at this site: http://www.irvineayrshire.org/propeller.htm Eisboch (Ho, ho, ho!) There's more than one way to screw. Here's a wiki entry: David Bushnell (1742 - 1824) of Saybrook, Connecticut, was an American inventor during the Revolutionary War. He is credited with creating the first submarine ever used in combat, while studying at Yale University in 1775. He called it the Turtle because of its look in the water. His idea of using water as ballast for submerging and raising his submarine is still in use today, as is the screw propeller, which was first used in the Turtle. While at Yale, he proved that gunpowder exploded under water. David Bushnell also made the first time bomb. With this, he also came up with mine barrage in 1777. He also invented the first time bomb. He combined his ideas in an attempt to attack British ships which were blockading New York Harbor in the summer of 1776 by boring through their hulls and implanting time bombs, but failed every time due to a metal lining in the ships hull to protect against parasites in their previous station, the Caribbean. David Bushnell then created the Turtle. The Turtle eventually sank. On June 8, 1781 he was promoted Captain of Sappers and Miners. Bushnell later traveled to France and then settled in Warrenton, Georgia where he taught at the Warrenton Academy and practiced medicine. He died in 1824, but before he died David was honored with a medal by George Washington. David Bushnell's Submarine Model is on display at the U.S. Navy Submarine Force Museum and Library in Groton, Connecticut. Another wiki: H James Watt of Scotland is generally credited with applying the first screw propeller to an engine, an early steam engine, beginning the use of an hydrodynamic screw for propulsion. Mechanical ship propulsion began with the steam ship. The first successful ship of this type is a matter of debate; candidate inventors of the 18th century include William Symington, the Marquis de Jouffroy, John Fitch and Robert Fulton, however William Symington's ship the Charlotte Dundas is regarded as the world's "first practical steamboat". Paddlewheels as the main motive source became standard on these early vessels (see Paddle steamer). Robert Fulton had tested, and rejected, the screw propeller. Sketch of hand-cranked vertical and horizontal screws used in Bushnell's Turtle, 1775 The screw (as opposed to paddlewheels) was introduced in the latter half of the 18th century. David Bushnell's invention of the submarine (Turtle) in 1775 used hand-powered screws for vertical and horizontal propulsion. The first screw propeller to be powered by a gasoline engine, fitted to a small boat (now known as a powerboat) was installed by Frederick Lanchester, also from Birmingham. This was tested in Oxford. The first 'real-world' use of a propeller was by David Bushnell, who used hand-powered screw propellers to navigate his submarine "Turtle" in 1776. The Bohemian engineer Josef Ressel designed and patented the first practicable screw propeller in 1827. Francis Pettit Smith tested a similar one in 1836. In 1839, John Ericsson introduced the screw propeller design onto a ship which then sailed over the Atlantic Ocean in 40 days. Mixed paddle and propeller designs were still being used at this time (vide the 1858 SS Great Eastern). In 1848 the British Admiralty held a tug of war contest between a propeller driven ship, Rattler, and a paddle wheel ship, Alecto. Rattler won, towing Alecto astern at 2.8 knots (5 km/h), but it was not until the early 20th century paddle propelled vessels were entirely superseded. The screw propeller replaced the paddles owing to its greater efficiency, compactness, less complex power transmission system, and reduced susceptibility to damage (especially in battle) Voith-Schneider propeller Initial designs owed much to the ordinary screw from which their name derived - early propellers consisted of only two blades and matched in profile the length of a single screw rotation. This design was common, but inventors endlessly experimented with different profiles and greater numbers of blades. The propeller screw design stabilized by the 1880s. In the early days of steam power for ships, when both paddle wheels and screws were in use, ships were often characterized by their type of propellers, leading to terms like screw steamer or screw sloop. |

If I had a degree from Yale, I would keep quiet about. I would rather have a degree from Iowa State, which has a better engineering school. What kind of nuclear reactor do they have at Yale? How big is their particle accelerator? How is the vet school? Does Yale deal with anything of actual importance? I figure Yale English majors can drive cabs as well as those from anywhere else. I am not impressed with those who are particularly impressed with a Yale degree. Casady Loogy has an honorary degree from The Famous Nitwits School. Is there an Iowa State list like this one: There is no Harry Krause in this list of Yale graduates or any other list of Yale graduates. |

So, did he invent the screw propeller or did he invent a screw propeller driven submarine? Eisboch I don't think there is conclusive proof that any one person invented the screw propeller. My best guess is that Leonardo Divinci's drawings inspired more than one person. There may be several who all figured it out independently. They can all take credit without being dishonest. |
