Does anyone know if there’s a difference between an antiderivative and an indefinite integral? I’ve always kinda thought they were the same thing, although I’ve heard some people have different definitions for them.

OK, so. It’s June. The Yankees are 1 game behind the Red Sox. And ESPN is asking whether you think the Yankees must beat the Red Sox tonight.

How can this possibly be a “must win”? Are the Yankees going to be eliminated from playoff contention? All of a sudden, they’re going to lose confidence and become a .500 team? It’s not like there are more than 90 games left in the season.

The most frightening part is that 44% say it’s a “must win”. I really hope they’re joking.

Hope you enjoyed June 11th’s Tour of Stupid.

Has this work week been particularly stressful or frustrating? I leave you with this pick-me-up for the weekend — at least you’re smarter than the guys in the following story:

The menu at the Coffee Garden at 900 East and 900 South in Salt Lake City has included a scrumptious selection of quiche for about 10 years.

The recipe calls for four fresh eggs for each quiche.

A Salt Lake County Health Department inspector paid a visit recently and pointed out that research by the Food and Drug Administration indicates that one in four eggs carries salmonella bacterium, so restaurants should never use more than three eggs when preparing quiche.

The manager on duty wondered aloud if simply throwing out three eggs from each dozen and using the remaining nine in four-egg-quiches would serve the same purpose.

The inspector wasn’t sure, but she said she would research it.

You are at a party with 22 other people.

1. Estimate what the chances are of at least two people at the party having the same birthday.

2. Now calculate it. (For simplicity, feel free to assume no one was born on Feb. 29)

Yes, I was surprised.

You know what I discovered?

e ^πi = -1 (that’s e ^ (pi * i) = -1 if it didn’t display properly for you)

How freaky is that? (Explanation here.)

For those of you who read The Daily WTF: obvious troll is obvious. (Yes, aware that annoying meme is annoying, deal with it.) I can’t believe how many people have taken commenter Top Cod3r seriously.

: I didn’t really have anything to say, except that we have a little Mr. E icon now for when I have an aside. And, uh, stay in school and don’t do drugs.

Today’s π day. March 14 is 3/14 and π is 3.14…. 3.1415926535 was as far as I cared to memorize, and even that was a waste of time.

This is a perfect day to share any π-related stories. My favorite is the day I learned about radians as an angle measurement and that a circle was 2π radians. 11th grade, I think. That had a profound effect on my future development as an adult.

Additional reading: piday.org is supposed to be the “official” π day site (at least, it’s the first site that showed up in Google).

In college football (American), a ton of people start calling every year for a playoff system to replace the BCS. (Quick primer: usually, a champion of a sports league is determined by a playoff between teams who did the best during the season. Instead, the BCS determines the top two teams by a combination of human and computer polls, essentially creating a 1 game playoff.)

What people don’t think about is that a playoff system is not very likely to crown the best team in the country as champion.

Let’s take an 8-team playoff, for example, and have University of A to be “objectively” the best team in the country. And let’s assume the UA team is so good, it will defeat other elite ( top 8 ) teams 75% of the time. UA will have to win three games in a row, which it has a 42% chance of doing. This speaks highly of UA, but their chances of being recognized as champions are still worse than a coin flip.

The 75% number is higher than can be expected. 60% may be closer to realistic, giving the best team a 21% chance of winning the crown.

If that’s the system people want, then by all means they can clamor for it. As long as they recognize it’s unlikely that the best team in the country will be known as the champions. (College basketball is even worse for determining the #1 team, but everyone likes gambling on March Madness so no one brings it up).

My biggest beefs with the BCS system are:

1. Human pollsters, who cannot have knowledge of every single game played, cannot possibly hope to compare all teams adequately, and have ingrained biases, are given greater weight than the computers.

2. The computer polls are forced not to considered margin of victory in their calculations. This can throw them out of whack, as this story on Jeff Sagarin’s rankings indicates (at one point, North Dakota State was ranked in the top 20). I guess for some reason, the BCS thought that maybe these programmers wouldn’t have developed algorithms that made sure a 52-point victory didn’t mean more than a 35-point victory.

In other words, the BCS has to give computers less weight, because their own rules make computers less accurate in predicting the top two teams.

If it were up to me, I’d eliminate computer poll restrictions, and completely ignore the humans. The only check would be at the end of the year, a council would get together that could veto the computers’ selection if 75% agreed, at which point the human polls would be used to determine the game.

This is mostly off-the-cuff, so blast away with holes in this thinking.

Dr. Gene Ray, Cubic continues to enlarge the quotation rotation with more hits:

“ONEism is demonic Death Math. I have so much to teach you, but you ignore me you evil asses.”

“Your opposite eyes were moved to 1 corner to overlay for single perspective, but that corrupts your Opposite Brain. Hey how about making a donation to Gene Ray, 2580 Highland Pointe Dr. Cumming, Georga 30041.”

So now we need to be told more food means more calories? Whoever created the chart accompanying the story must have decided Americans are that bad at math. (To be fair, the story itself seems fine.)
