Didn't Whitney invent the concept of geometric tolerances (limits and fits) thus allowing the interchangeability of parts?loseyourname said:Where did you get this from? I've been looking up sources to be sure, and everything I come up with says that Ransome Olds was the first manufacturer to use an assembly line and that Henry Ford was the first to use an assembly line on a conveyor belt, which is when modern factory techniques really took off. Whitney may have started mass production, but you might be giving him too much credit to give him the assembly line.
Yeah, its often the little things we take for granted that have the most profound impact.quetzalcoatl9 said:Oliver Evans, the inventor of the refrigerator.
I believe that this is an invention which does not get the credit due. The refrigerator has made starvation a thing of the past for countries with energy/electricity. It also made food a semi non-perishable, so that most of us can devote our lives to things other than gathering food and leave that to others in a more manageable way.
Limits and fits is very diffferent than GD&T. I have a few sources on GD&T and I can't nail down a single "inventor" of GD&T. Although, e-funda has about the best short description:Art said:Didn't Whitney invent the concept of geometric tolerances (limits and fits) thus allowing the interchangeability of parts?
I think the big swing in the development came when Taguchi came about with his pre six sigma quality stuff at Motorola.Geometric Dimensioning and Tolerancing symbols have been in use since at least the turn of the century. GDT was especially important during the Second World War in relation to extremely high volume production of Liberty Ships, aircraft, and ground vehicles. The automotive industry, with its high volumes, has also benefited from GDT. The computer industry, in particular mass storage manufacturers, have used GDT extensively to increase their yields of high-volume and low-margin hard disk drives. However, as with most engineering and scientific methodologies, GDT was not rigorously established and documented until later in the twentieth century. The American National Standards Institute publication in 1982 of ANSI Y14.5M-1982 was a turning point in the rigorous, unambiguous standardization of the methodology.
I don't understand why you say they are different? Limits and fits as devised by Whitney to allow the mass production of muskets is a system which acknowledges the impossibility of ever making 2 parts identical and so instead limits the degree of variance to specific parameters, i.e. dimensions are specified in the form 100 +/- 0.01 for example. Geometrical tolerances is an expansion of this idea using standard notation to cover the 4 areas which an engineering machinist might want to control.

So helping and causing are two different things, and 'helping' was only possible due to timing. That means Reagan was not responsible for the collapse of the USSR, in that you have to be the cause of something to take credit for the effect.russ_watters said:...That is precisely what I'm arguing: that Reagan accelerated the collapse of the USSR.
I only asked this because it seemed some were arguing that Reagan should be #1 because he was responsible for the collapse of the USSR. I just wanted to clarify consistency in position on both of these arguments.russ_watters said:No I don't - a question which I answered in post 31![]()
GD&T is a much more precise tolerancing scheme that accomplishes things that standard limit tolerancing can not. It's based on a part's function or it's relation to another part. For example, you can not (or would be extremely difficult) to limit tolerance the position of a hole to three datums, which you can do with one callout in GD&T. The two are completely separate beings. They are used in conjunction.Art said:I don't understand why you say they are different?

That depends on what specifically you are talking about him "causing". He certainly "caused" the acceleration of the collapse. He certainly "caused" the USSR to collapse sooner rather than later. He is therefore certainly responsible for that effect.Informal Logic said:So helping and causing are two different things, and 'helping' was only possible due to timing.

No problem - just don't jump to conclusions about my opinions. This shouldn't be an issue because I am very open about them.I only asked this because it seemed some were arguing that Reagan should be #1 because he was responsible for the collapse of the USSR.

It depends on what you mean there - with Bush and, say, Lebanon, the only effect Bush could have had was indirect (ie, that he scared Syria into leaving without doing anything specific to actually threaten them). While it may be true it is impossible to prove unless 20 years from now a Syrian leader writes a book and says 'we left Lebanon because we were afraid Bush would attack us if we didn't.' Reagan had a direct effect on the USSR in that they changed internal policy in response to his policies - and years later, Russian officials did say precisely that.And as was posted earlier, the same 'cause and effect' logic applies to Bush in regard to "democratic practices" such as elections, specifically in the Middle East. These are all the same kind of reasoning/arguments running through several threads.

You may believe you are dictator of the world, but no, I don't need to do anything.russ_watters said:And since I am the one who made the specific claim and you are the one responding to it, you need to follow my meaning: that Reagan caused the acceleration of the collapse. Otherwise, you're arguing a straw-man.
Just policing the police. Is it annoying? Now you know how it feels.russ_watters said:No problem - just don't jump to conclusions about my opinions. This shouldn't be an issue because I am very open about them.
Indirect is the key word. The bottom line is that all other variables needed to be in place, meaning timing in the chain of events (in the case of Lebanon, the death of Arafat, etc.). Economic decline, corruption, death of leaders either naturally or by assassination, wars, religion, etc., etc., etc. are much stronger catalysts for such events. But you will believe what you want to believe about your precious Republican presidents.russ_watters said:It depends on what you mean there - with Bush and, say, Lebanon, the only effect Bush could have had was indirect (ie, that he scared Syria into leaving without doing anything specific to actually threaten them).

Your forget Archie Bunker, he comes close to my proposal, Werner Von Braun, only he was smarter and imported from Germany. He was an example of how the US deals with dictator's akolytes. I just wonder how many captured Iraqi Baathists are working in the States now.Andy said:Well as far as I am concerned there is only two candidates for the greatest American.
