Not the center of the universe

This is amazing: http://primaxstudio.com/stuff/scale_of_universe/.  After it loads, move the gray-square-button-slider under the picture to the left to see smaller, and to the right to see larger.

Looking at something like this really makes me appreciate how vast everything is, also puts into perspective how minor my problems and worries are.  A teeny blip in the grand scheme of things.  How lucky we are, with everything out in the universe (or multiverse) to have things in our world that are so pleasant, like music.

Speaking of music, careful, there’s music on the site! It’s not loud or annoying, but be aware in case you are at work and decide to peek.

ARGUMENTUM AD IGNORANTIAM

Sunday, July 22nd, 2007

Just read this on another blog, and have to put it here so I don’t forget it. I refer to this concept quite frequently, but didn’t realize that it was put together so succinctly already.

ARGUMENTUM AD IGNORANTIAM

An argument that a proposition is true because it has not been shown to be false, or vice versa. Ad ignorantium arguments are also known as “appeals to ignorance.” This fallacy has two forms:

1. P is true, because it has not been proven false.
2. P is false, because it has not been proven true.

going postal

Friday, May 11th, 2007

The cost of a first class stamp is going up, when, Monday? So I made my usual trip to the post office (not the one in Gloucester; another one which shall remain anonymous) to exchange the two unopened rolls of 39¢ stamps I have, and pick up another 60 2¢ stamps for the open roll of stamps I have.

Now let me digress for a moment to state that we rarely use stamps. I have so many because I have a rule (we OCDers have lots of rules) that once I open the last of something, I must get more immediately so I don’t run out. Well, if you order stamps online, shipping costs the same regardless of whether you order one or two rolls of stamps, so to save the 50¢ and the time spent ordering, I usually order two rolls.

Anyway, so I’m at the aforementioned post office and ask to exchange/return my old stamps. Despite having done this before at this exact post office, I was told that they cannot take back stamps, and if I’ve ever looked at my receipts, I’d have noticed that “all [stamp] sales are final.” So being the constant questioning person I am, I asked WHY won’t take stamps back. The response (in the words of Dave Barry, I am not making this up)?

“Because all sales are final.” WOW! I’m glad I got that cleared up!

I purchased 260 two-cent stamps and left.
