### Re: RuPaul's Drag Race

When I first heard the title, my interest was piqued. Then I realized my first instinct was wrong, and it wasn't a bunch of drag queens in a cross-country drag race, ala Cannonball Run, my interest disapated, like a bad fart in the wind. There's this amazing browser called Mozilla Firefox that come...

### Re: Proof that the sqrt of 2 is irrational?

I'm not necessarily concerned with whether that argument can be generalized to the division algorithm, but more precisely whether or not the division algorithm is necessarily true in order for that argument to be valid. If it isn't necessary, then I think you can show the irrationality of 2  withou...

### Re: Proof that the sqrt of 2 is irrational?

Suppose that positive integers may be neither even nor odd, and let m be the smallest such integer (Well-Ordering Axiom). Call it m. Then m - 1 must be either even or odd. If m-1 is even, then it can be expressed as 2k, k some positive integer. Then m - 1 = 2k, so m = 2k + 1, and m is odd by defini...

### Re: Sum and Product Man

I need to change it; I should have said less than OR equal to 54, or less than 55. The first statement made by Product also means the prime factorization of the product can't have a prime factor over 50. If it did, the two numbers would have been immediately deduced. Since Sum knew product coul...

Euclid's Lemma (or a corollary) is necessary to show that prime factorizations are unique. However, Euclid's Lemma is NOT necessary to show existence. This is true for the integ...

### Re: Proof that the sqrt of 2 is irrational?

Let m be odd. Then m may be written as 2k+1, where k is some positive integer. This statement requires the division algorithm, which immediately implies FTA. The statement does not require the division algorithm. It merely requires the definition of "odd" in the integers. And a proof that...

### Re: Analytical Cooking... What do you think?

I try to use this analytical cooking concept, to one degree or another, in all of my cooking. Of course, depending on how gung ho you are, you'll need some gear. I find my thermometer and scale to be valuable tools in the kitchen. My first analytical experience: My friend got me some gourmet coffee....

### RuPaul's Drag Race

So, I rarely watch TV, and LOGO would not be my first channel. Plus, I don't really go for most reality shows. But, I LOVE this one. I find it hilarious and entertaining. So what do you think? We're down to just a few contestants now. I don't know about you guys, but I totally thought Rebecca should...

### Re: Sum and Product Man

I know this is an old post, but I thought I would mention that this is a rather famous problem. Also, Dijkstra famously published a solution that he supposedly did in his head. Anyone that sees this and ends up with many many cases to check, there is a way to severely limit everything. Slight spoile...

### Re: Proof that the sqrt of 2 is irrational?

You do not need the Fundamental Theorem of Arithmetic for this proof. The statement "If m^2 is even, then m is even." does not require that. Proof: I will demonstrate the logically equivalent contrapositive "If m is odd, then m^2 is odd." Let m be odd. Then m may be written as 2k...

This all makes a lot of sense. I was already kind of doing like mrbraggins, where my system volume is at about 80% constant. But now I have some good reasons for doing this. Thanks!

### Proper place to modify volume

I don't think this belongs in Help Desk... Where should you modify the volume on your computer? For example, right now I have application volume control, OS volume control, and volume control for my speakers. If I want things to be louder or softer, where should I go and why? I'm not interested in p...
