A little math humor
When it comes to sample variance ...
http://en.wikipedia.org/wiki/Variance
The two estimators only differ slightly as we see, and for larger values of the sample size n the difference is negligible. The second one is an unbiased estimator of the population variance, meaning that in a large number of repetitions its average value tends to the right value of the population variance. The first one may be seen as the variance of the sample considered as a population.
One common source of confusion is that the term sample variance may refer to either the unbiased estimator s2 of the population variance, or to the variance σ2 of the sample viewed as a finite population. Both can be used to estimate the true population variance. Apart from theoretical considerations, it doesn't really matter which one is used, as for small sample sizes both are inaccurate and for large values of n they are practically the same. Intuitively, computing the variance by dividing by n instead of n − 1 seems to underestimate the population variance. This is however not the case because we are using the sample mean \overline{y} as an estimate of the unknown population mean μ, and the raw counts of repeated elements in the sample instead of the unknown true probabilities.
In practice, for large n, the distinction is often a minor one. In the course of statistical measurements, sample sizes so small as to warrant the use of the unbiased variance virtually never occur. In this context Press et al.[1] commented that if the difference between n and n−1 ever matters to you, then you are probably up to no good anyway - e.g., trying to substantiate a questionable hypothesis with marginal data.

Nothing to report
I'm sure a title like, "Nothing to report" isn't going to grab the attention of too many readers, but I'd hate to fill the world with the false hopes that would accompany such headlines as, "Incredible breakthrough in [something of interest]" or "New discovery in [your field of study]." So, while leaving such headlines and the stories worthy of them to the blogging professionals, I humbly share the information that I have.
First, I would like to recommend the JVC GZ-MC200 Digital Video Camera. It's the video camera I used to make the documentary on my snail. It's small, has 4 GB of memory, and can zoom in really far. It's really a lot of fun. If you use Economy quality recording, you can record over 5 hours of video, which was more than enough to cover the documentary of my 5 day vacation. Which brings me to my next recommendation.
I would like to recommend any car rental company except Hertz in the Salt Lake city area. The service is just too slow.
I would like to recommend sunscreen for obvious reasons. My post-lake activities were comfortable and pleasant thanks to about a half a bottle of SPF 45 sunblock.
My hat goes off to M. Night Shyamalan and "Lady in the water." The movie made me jump 4 or 5 times. Most of which were caused by simple things, like the sprinklers turning on. Coming home that night and being a little bit scared of my lawn is a wierd feeling as well. A movie with an entertaining yet simple plot that leaves you with something to ponder. I'd recommend it.

Gary the Snail
Nothing exciting happens at the end. He is just a snail. I increased the speed to be four times the normal speed. This is the first time I've made a documentary on snails.

Baby Got Book

Oh my goodness! Becky, look at her bible! It's so huge!
She looks like one of those preacher guy's girlfriends.
Well, who understands those preacher guys anyway?
They only talk to her because she looks like Mother Theresa. Ok!
But look at it, it's just huge. It's gross.
She just looks so ... righteous.
I like big bibles and I can not lie.
You christian brothers can't deny,
When a girl walks in with a KJV
and a bookmark in Proverbs you get stoked.
Got her name engraved,
So you know this girl is saved.
It looks like one of those large ones,
With plenty of space in the margins.
Oh Baby, I wanna read with ya,
Cause your bible's got pictures.
My minister tried to console me,
But that book you got makes me so holy.
Ooo Mama Mia,
You say you want koinonia
Well, bless me, bless me
And teach me about John Wesley
I saw her praying,
While I was DJing
She got grace ... pretty face
She ain't goin' down to the bad place
I'm tired of heathen guys
Sayin' they like pocket-size
Ask the average Christian to take a look
She's gotta pack much Book
So...Fellas (Yeah), fellas (Yeah)
Has your girlfriend got the Book (Oh yeah!)
Well, read it (Read it!), read it (Read it!), read that Holy Book
Baby got Book
Chorus
(NIV with a ribbon bookmark)
(NIV with a ribbon bookmark)
Baby got Book
(NIV with a ribbon bookmark)
(NIV with a ribbon bookmark)
I like 'em leather and bound
It's 50 pounds
I just can't understand
How it is, some weenie
Wants the Bible on CD
She wanna get you saved
Amen! Double up! A-men!
I ain't talkin' about a paraphrase
Cuz Paul wouldn't use those anyways
I like 'em real thick and red-lettered
You can't find nothin' better
Southpaw's in love
Bibles that big are unheard of
So I'm sittin' here thinkin' "What if...
I find me a girl that shows midriff?"
You can have those bimbos
I'll keep those chick that do devos
A word to the Christian sistas
I can't resist ya
I'll do God's time witcha
But I gotta be straight when I say I wanna pray
Til the break of day
Baby, got it goin' on
Like the wife in Proverbs 31
We just might get engaged
When we finish reading this page
Cuz it's worn and it's torn
And I know that girl's reborn
So ladies (yeah), ladies (yeah)
Do you wanna save people from Hades (yeah)
Then read it...'til the pages fall out
Even white preachers got to shout
Baby got Book
(Thompson Chain with big red letters)
(Thompson Chain with big red letters)
Baby got Book
Yeah baby
When it comes to a good book
Stephen King's resume just can't compare
39 + 27 = 66 books
And if you're Catholic ... there's even more
So your girlfriend quotes Bill Hybels
But does she got a big Bible?
Cuz that little things she's got won't start a revival
My Bible study don't want none,
Unless you got Book, Hon
...You can read Clancy or Grisham
But please don't loose this Book
Some brothers wanna play that hard role
And tell you that Book's too old
So they toss it and burn it
And I pull up quick to just learn it
So your girl likes paperback?
Well I ain't down with that
Cuz my girlfriend's hot her Bible's rockin'
And she's got good doctrine
To the atheist chicks who try to dis
You ain't it Miss Priss
Give me a Christian, I'm insistin'
And I'll greet her with some holy kissin'
Some pervert tried to chase
But he didn't make it past first base
She's quick to resist temptation
And she loves a new translation
So ladies who were lost and found
If you want the triple-six thrown down
Dial 1-800-reads-a-lot
And teach me about those Psalms
Baby got Book
(NIV with a ribbon bookmark)
(NIV with a ribbon bookmark)
Baby got Book
(Thompson Chain with big red letters)
(Thompson Chain with big red letters)
Bible college knowledge but she still got Book
Bible college knowledge but she still got Book
Bible college knowledge but she still got Book
Bible college knowledge but she still got Book
Whip.

Judge: What's with the clothes?
Juggler: Uh, we thought it would be better with clothes.

Baluga Bubble Rings

Wikipedia: Beluga
Beluga are highly sociable creatures. They move in pods which commonly contain animals of the same gender and age. Groups of males may number in the hundreds.
Belugas are slow-swimming mammals which feed mainly on fish. They also eat cephalopods (squid, octopus) and crustaceans (crab, shrimp). Foraging on the seabed typically takes place at depths of up to 1,000 feet, but they can dive at least twice this depth.
Beluga exhibit a wide range of vocalisations including clicks, squeaks, whistles, squarks and a bell-like clang. One noted researcher in the field likens a noisy Beluga pod to the string section of an orchestra tuning up before a concert. Researchers have recorded 50 distinct sounds; most in the range of 0.1 to 12 kHz.
Their main natural predators are polar bears, especially when the whales become encircled and trapped by ice. The Bears club the trapped whale with a paw and then drag it on ice for a feast. Beluga are easily small enough to also be a target for an orca.

Kids' videos, I like kids' videos. I like the way that they help firefighters get to fires.
No, no, no. That's a fire truck.
Right, yes.
