Why Does Old Ice Cream Get Crunchy?

This was originally posted on Sustainable Nano, which is my new project.  You should go check it out!  Science Minus Details will live on though! Poop posts will come, have faith!!!!

As with all good meals of information, let's start this one off with ice cream!

In an effort to grow out of my "slim fit" clothes, I've begun an ice-cream-after-every-dinner diet.

Even the cat likes my diet!

An added bonus is that I go through jugs of ice cream so quickly that I NEVER have to deal with old, gross, crunchy ice cream! You know what I'm talking about. You reach into the back of your freezer, find that jug of 6-month-old ice cream, only to discover that it tastes like the perfect mixture of sugar, fat, and sand.

Asteroid Particles

Recently the Japanese Aerospace Exploration Agency sent a spaceship to an asteroid named Itokawa.  A spaceship to an asteroid!!  As if that wasn't awesome enough, the spaceship landed on the asteroid, collected material, and returned home to earth!  These are images of tiny particles collected from the surface of that asteroid.

These particles are around half the diameter of a human hair.  Click to make them HUGE!

Here are three views of Itokawa, which is about 630 meters x 250 meters.  Assuming a spacesuit didn't slow you down, and the surface of the asteroid were boulder-free and easy to walk on, it would only take you ~20 minutes to walk around the whole thing the long-way.  Pretty small!!

Solar Beat

File this post under my constant quest to rise above the constraints of my perception of time and space.  The people at whitevinyldesign.com made this awesome little animation thing of the eight "classical planets" plus the "pluton" (formerly known as a planet) pluto and the "dwarf planet" (formerly known as an asteroid) ceres orbiting around the sun.  You can speed them up and slow them down and listen to their 10 unique tones.  I seriously spaced out for 10 solid minutes while watching this thing, I encourage you to do the same.

Isn't it cool how the innermost planets move soooooooo much faster than the outermost planets?  Makes me think of how a penny circles faster and faster around the central axis of one of those spiral wishing wells as it gets closer to the center.  Conceptually identical.

The Grand Canyon Rules, pt 1

Recently I went to the grand canyon, which is one of the top five most amazing sights I imagine I will ever see in my life. Here is a picture of me at the north rim:

Me, Mind Being Melted.

At the visitors center, on the side of an awesome miniature model of the canyon, there is this amazing quote from geologist Clarence Dutton (1841-1912) that sums up quite well how I feel when standing on the edge of the canyon:

Dimension means nothing to the senses, and all we are left with is a troubled sense of immensity

Krakatoa

This is what the volcano Krakatoa looked like before it exploded in August 1883:

This is what it looks like now, the three islands forming what used to be the perimeter of the pre-1883 volcano:

Today we're going to talk about what you can see and can't see when you look up into the night sky. Let's see where it takes us.

Step outside tonight and gaze into the heavens. Almost all of the lights you see up there are stars that are in our very own milky way galaxy. If you're like me, you live in a city and can't see but a handful of stars. So, thanks to the wonders of modern technology, here is what the sky looks like from the middle of the desert (definitely click on this to see the big version, definitely).

Paul McCartney = the Universe

Paul McCartney at coachella 2009 was probably the best show of my life. It had everything, and made me think a lot about the universe. Read on. I could not stop feeling that this was probably one of the most amazing things ever witnessed on planet earth, ever. The songs were so perfectly crafted, the jumbo-tron so big, the fireworks so bright.

All this, happening in the middle of the desert. An artifical oasis. We drove all day, knowing that hundreds of gallons of clean, fresh water had been shipped to the middle of the desert for us, grass grown on sand for us, tents, pools, tesla coils, flames.... unbelievable. We live like kings.

Between songs McCartney addressed the crowd: "hello coachella, california, usa, earth, solar system, galaxy, universe!" Try going through this in your head from where you are right now, picturing each step...i mean it, don't just read, try it...go slow, it's better that way I think... couch, house, berkeley, california, usa, earth, solar system, galaxy, universe. I stop being able to imagine it realistically somewhere between california and earth. It's impossible to really comprehend, how tiny we are relative to everything else. The known universe is so huge relative to the milky way galaxy, which is enormous relative to planet earth... and so on.

This thought process was even more incomprehensible in front of Paul McCartney. If this show, at this time, in this place, was as huge and amazing as it seemed to be... and I think it was...then how could I possibly imagine anything bigger. How insanely big is the earth, solar system, galaxy, universe? Think about it. Would the concert have blown my mind if I was watching it from another planet?

Which is more amazing, the existence of the universe, or the existence of life within it?
