Re: [Texascavers] karst on Saturn's moon
Bill, The problem is in the fourth step. For it to be equivelent you have to square the whole function on each side not the invidual variables. For example the square of 2 plus the square of 3 are not equal to the square of (2+3). Besides a-c is the square root of a2-2ca+c2 not a2-ca+c2 Josh On Fri, Mar 5, 2010 at 4:08 PM, Ed Goff wrote: > If a is going to turn out to equal b, then a-b has to be 0, therefore in > your first step you multiplied both sides of the equation by 0.

Re: [Texascavers] karst on Saturn's moon
If a is going to turn out to equal b, then a-b has to be 0, therefore in your first step you multiplied both sides of the equation by 0. In caving terms, this would be equivalent to the following: If you start out in a cave with 2 stalactites of equal length, and you break both of them off and throw them away, they are still equal.

Re: [Texascavers] karst on Saturn's moon
To Fofo and all, With reference to phd comics! One can easily prove any two numbers equal. I remember this from high school days ugh, 50 some years ago: Given: One can maintain the equality of an equation as long as the same operation is done to both sides. a+b=cMultiply both sides by (a-b) a2-b2=ca-cbSubtract ca from both sides, add b2 to both sides a2-ca=b2-cbComplete the square by adding c2/4 to both sides a2-ca+c2/4=b2-cb+b2/4 now take the square root of both sides a-c/2=b-c/2Add c/2 to both sides a=b Beautiful -- right? Try substituting real numbers such as 2+3=5 and maintain the format. Results: 2=3. What does this have to do with caving?? It sure could screw up our surveys! I bet the press would have fun with this. OK where is the fallacy?

[Texascavers] karst on Saturn's moon
Where do they find those idiots to write press releases? That area in Utah is just a classic stream-dissected plateau, not karst. Look at the photo right-side up and that's obvious. The link to a larger view of the Titan photo doesn't work, so I'll reserve judgement on that one, but I do wonder whether what looks like sinkholes might turn out to be plateaus if the photo is rotated. -- Mixon Nature is a hanging judge.
