Jazz Party!!!

Today I had a jazz class. (Jazz 1-A.) We had the funnest party ever!!!!!! First, we opened presents, then we had cookies and hot chocolate, next we played games.One game was Four Corners. Then we played 12345 go jump! You play 12345 go jump by when someone says one, you jump! you can only jump on 1 and 3. If you don't, or do late, your out! At the end we got sillybands and a candycane!

Einstein's 'Biggest Blunder' Turns Out to Be Right

Einstein's 'Biggest Blunder' Turns Out to Be Right By Clara Moskowitz SPACE.com Senior Writer posted: 24 November 2010 01:16 pm ET I love learning more about space. This is an article from space.com

What Einstein called his worst mistake, scientists are now depending on to help explain the universe.

In 1917, Albert Einstein inserted a term called the cosmological constant into his theory of general relativity to force the equations to predict a stationary universe in keeping with physicists' thinking at the time. When it became clear that the universe wasn't actually static, but was expanding instead, Einstein abandoned the constant, calling it the '"biggest blunder" of his life.

But lately scientists have revived Einstein's cosmological constant (denoted by the Greek capital letter lambda) to explain a mysterious force called dark energy that seems to be counteracting gravity — causing the universe to expand at an accelerating pace.

A new study confirms that the cosmological constant is the best fit for dark energy, and offers the most precise and accurate estimate yet of its value, researchers said. The finding comes from a measurement of the universe's geometry that suggests our universe is flat, rather than spherical or curved.

Geometry of the universe

Physicists Christian Marinoni and Adeline Buzzi of the Universite de Provence in France found a new way to test the dark energy model that is completely independent of previous studies. Their method relies on distant observations of pairs of galaxies to measure the curvature of space.

"The most exciting aspect of the work is that there is no external data that we plug in," Marinoni told SPACE.com, meaning that their findings aren't dependent on other calculations that could be flawed.

The researchers probed dark energy by studying the geometry of the universe. The shape of space depends on what's in it — that was one of the revelations of Einstein's general relativity, which showed that mass and energy (two sides of the same coin) bend space-time with their gravitational force.

Marinoni and Buzzi set out to calculate the contents of the universe — i.e. how much mass and energy, including dark energy, it holds — by measuring its shape.

There were three main options for the outcome.

Physics says the universe can either be flat like a plane, spherical like a globe, or hyperbolically curved like a saddle. Previous studies have favored the flat universe model, and this new calculation agreed.

Flat universe

The geometry of space-time can distort structures within it. The researchers studied observations of pairs of distant galaxies orbiting each other for evidence of this distortion, and used the magnitude of the distortion as a way to trace the shape of space-time.

To discover how much the galaxy pairs' shapes were being distorted, the researchers measured how much each galaxy's light was red-shifted — that is, budged toward the red end of the visual spectrum by a process called the Doppler shift, which affects moving light or sound waves.

The redshift measurements offered a way to plot the orientation and position of the orbiting pairs of galaxies. The result of these calculations pointed toward a flat universe.

Marinoni and Buzzi detail their findings in the Nov. 25 issue of the journal Nature.

Understanding dark energy

By providing more evidence that the universe is flat, the findings bolster the cosmological constant model for dark energy over competing theories such as the idea that the general relativity equations for gravity are flawed.

"We have at this moment the most precise measurements of lambda that a single technique can give," Marinoni said. "Our data points towards a cosmological constant because the value of lambda we measure is close to minus one, which is the value predicted if dark energy is the cosmological constant."

Unfortunately, knowing that the cosmological constant is the best mathematical explanation for how dark energy is stretching out our universe doesn't help much in understanding why it exists at all.

"Many cosmologists regard determining the nature of dark energy and dark matter as the most important scientific question of the decade," wrote Alan Heavens of Scotland's University of Edinburgh in an accompanying essay in the same issue of Nature. "Our picture of the universe involves putting together a number of pieces of evidence, so it is appealing to hear of Marinoni and Buzzi's novel technique for testing the cosmological model, not least because it provides a very direct and simple measurement of the geometry of the universe."

Bunny

Today at school the desks were changed (as in switched around in different places.) I'm surrounded by boys, with the exception of two girls. THANK GOODNESS! :(. But... before recess I decided I liked my spot. And how crazy is that?!? Well anyways, Mason (one of the boys next to me) said the bunny's head is dead. So today I made up a nick-name for everyone who sat around me. Mason: BunnyYou, Grey: BunnyTwo, Nick: BunnyShoe, Lexi: BunnyRoo, Amy: BunnyMoo, R`emi: BunnyPooh. Oh, and me, BunnyFoo! And I almost forgot! My teacher is BunnyDo. Hehe! :D THE END OF BUNNY

:)

Upsidown me. XD

Last knight I went in my moms room so she could read to me. When I went in there I sat on the bed. There was a book, and I thought everything was upside down!!! XD I asked, "Why is everything upside down???" Her answer was, "It's not upside down." I flipped it over, and it happened to be that I was reading it upside down! I was like, Oops! The book was called 'Never Mind'. Idk what it's about. Here is a picture of the book.>>>>>>>>>>>>>>>>>>>>

Funiest Things Ever!

HAHAHAHAHA! I found a website. It is: http://www.photofunia.com/. You can make these pictures yourself! First you need to get a picture of someone. Then go to the website! Stay on the Ads Friom Google. Click on a picture that shows up! Then hit browse and chose one of your saved pictures. Hit open. Then left click on the picture you made and hit Save picture as...

then name the picture! These are two I made!

Graduation

I graduated from piano Suzuki book one a few weeks ago. I got a trophy and i was really exited. After i got my trophy, we had strawberries and whipped cream. I had plain strawberries. Then i played with a friend named Alexis.(Lexi)
It was very fun. And now its time to pass my brother.

The Santa Barbara StoryFaire

At the Book Fair I met Valerie Tripp, the author of the American Girl books. She signed several books for me. She looked axactly like Kit Kittredge. I had my Kit doll with me and they looked alike. Two things I thought were interesting about Valarie Tripp were that she wrote the first American Girl book and she gets to choose how the American Girl Dolls look.

Valerie Tripp wrote the book "Meet Molly" based on what happened to herself one Halloween Night. Also at the book fair I met Greg Trine, the author of "Melvin Beederman, Super Hero." The first book is "Curse of the Bologna Sandwich." His books are very funny. Then I met Bruce Hale, author of "Chet Gecko." The main character of this book is the Gecko.

I had a lot of fun at the book fair. We had lunch afterwards at Natural Cafe, followed by yogurt at Yogurt Land. Yum.

Space V.S. Astronout

I want to be an astronout when I grow up. I learn alot about space by reading listening watching and look up stuff. There'sall different types of eclipses. There's a Luna Eclipse Solar Eclipse and a plane Eclipse. This is a picture of a Ecipse. Astronouts can die from the presoour of space. There is zero gravity in space. In space you're hair looks like static electrisity in space. To the right are instructions of how to make a space shuttle.

Super Bowl

My mom,dad,uncle Al, and me all voted for the saints. Only my brother voted for the colts. The colts have already won twice. My dad said that probably most of the world is voting for the saints since they have never got in the super bowl. I can't believe the Saints won. This time I acsully wacthed the super bowl.

I Play the Piano

I'm a piano player. My piano teacher's name is Kathryn. I play piano at my house and her studio. Kathryn is super nice. I'm almost done with Suzuki book one. I love it. Right now I'm playing Christmas Day Secrets and am learning My Heart Will Go On. It's the love theam for Titanic.

Fairys DO Exist

This is a real fairy and to the left is real fairy dust. I believe that I'm a fairy myself. people think that fairies are just myths but that's not true. My friends believe in them and want to be fairies now. I've told them every thing I know about them. Each day telling them something different each day. Fairies are amazing!!There's a bunch of different kinds of fairies. I can name almost every type. There's:
worker fairies, flower fairies, ice fairies, snow fairies, light fairies, animal trainer fairies, marble fairies, lava fairies, and lots more. the meanest fairies of them all are the undenes. There the water fairies. They make the water shimmer. My friend Marina, Olivia B., and me are going on a mission to save the fairies and fairy wold. Were the last hope.
