### Re: C# inheritance

I think the best way to solve this is to add a property to the Rectangle class called IsSquare, which would return Width == Height. My reasoning here is that, when we say, "A square is a kind of rectangle," we really just mean to highlight something special about the rectangle. You don't n...

### Re: The Four Commanders

As far as I can tell, there's no way to distinguish between the following two scenarios. Assume that no trickery is involved, and use the solution presented by sixes_and_sevens: A & B vote to attack, C votes to withdraw. D is a traitor and thinks they should attack, so he votes to withdraw. A &a...

### Re: Relatively prime

After a few minutes or so of thought, it hit me very suddenly that n and n+1 can't possibly share prime factors. I had never heard of this problem before, so I'm glad I was able to solve it relatively quickly and on my own. The only thing I don't get: What is the significance of making the set [...

### Re: Logical equivalence

Here's my unqualified input:

Although statement A and statement B can never both be TRUE, they can both be FALSE if only Al is present or only Bill is present.
This is shown in your table. In the second and third rows, (A^B) == (~A^~B), so it can't be a negation.

### Re: Programming a Magic: The Gathering game

Thanks for providing that link. I suppose the best way to do this would be to look for certain phrases on the cards. So the phrase "from (firstZone) to (secondZone)" means it is an example of 112.5i, and it functions only in firstZone. 112.5i An ability whose cost or effect specifies that ...

### Programming a Magic: The Gathering game

To any advanced player of Magic: The Gathering who is also a programmer: If you have ever read through the comprehensive rules, it seems almost like the game was designed with a specific programming strategy in mind. The most obvious example is the use of "the stack" in the game behaving e...

That last verse hits a little bit close to home over in NJ (but it should apply to anywhere in Suburbia). At least when they label the grass over here, it becomes a "protected state area", so maybe it's not a bad thing after all. Randall did a good job there of balancing between satire and...

### Re: "Savannah Ancestry" discussion (#775)

See, what I thought about this comic was that the guy really is talking about how he feels women are predisposed to be worse at math. When the girl catches him and points out the sexism of his statement, instead of admitting it, he just digs himself deeper by turning it into a "your mom" j...

### Re: RELATIVITY QUESTIONS! (and other common queries)

Thank you for your help, doogly. I still have a bit of thinking to go, but using Minkowski diagrams, I have pinpointed the flaw in my reasoning. The two billiard balls in my previous example can begin to accelerate simultaneously in the rest frame of my room, or in the rest frame of 0.86c relative t...

### Re: INTRO THREAD THE THIRD

Hello. My name is Mike. I'm 22, and I'm into things like language, physics, and math. My current project is to gain a functional understanding of quantum mechanics, and so far I am confused (although I am told this is the correct response).

### Re: RELATIVITY QUESTIONS! (and other common queries)

I have a question about length contraction, similar to the ladder paradox, but a bit different. First, to make sure I understand correctly so far: If a 12-inch ruler were to move past the chair I'm sitting in, and it were traveling at 0.86c, it would appear to me that the ruler were only 6 inches. L...
