When A Leaf Turns

A website dedicated to the hardworking men and…uh…other men who dedicate their Decembers to bringing joy (or something anyway) to kids everywhere.

When the hacked emails first came out, I said they would be a quote miners heaven. I was right, but to a much, much lesser extent than I would have thought possible, which is saying a lot. It’s amazing how little material the climate deniers have actually found to backup their claims of conspiracy.

And then someone goes and makes a video like this, blasting the two most “damning” quotes out of the water.

As usual it’s not looking good for the deniers, and I’m sure that as usual they’ll simply ignore that fact and continue to proudly proclaim their “victory”.

Imagine a death metal band with a banjo player. That’s how strange this match up is. But it is awesome nonetheless!

In case you’re not sure.

I’m not sure that this is related the way that I think it might be, but the latest Radio Lab Podcast had a segment on the fact that very young children think of numbers logarithmically. Perhaps our difficulties with scale and magnitude are a reflection of this natural understanding of numbers (rather than our “unnatural” understanding of numbers as serial).

I think people automatically think on a kind of logarithmic scale when contemplating extraordinary distances simply because the analogies used by our intuition cause magnitude to be lost. The moon orbiting the earth is roughly analogous to the earth orbiting the sun and so our minds map the moon to the earth and the earth to the sun, and the difference in magnitude is lost. We look at a galaxy and it appears roughly similar to the solar system. We can tell ourselves that the galaxy is incomprehensibly larger, but in our heads we see a solar system and the size difference is reduced to “It’s like this, but bigger.” We look at the universe, at all of the galaxies out there, and it appears roughly similar to the stars in our own galaxy. “It’s like our galaxy, but bigger.”

My hope is that these resources might help you get a grip on the actual sizes involved when thinking about the universe.

First, this website (http://www.phrenopolis.com/perspective/solarsystem/) shows the solar system to scale. According to the site: “This page shows a scale model of the solar system, shrunken down to the point where the Sun, normally more than eight hundred thousand miles across, is the size you see it here [approximately 6 inches]. The planets are shown in corresponding scale.”

Next a comparison of celestial bodies, including the planets and various types of stars.

Finally, the Hubble Ultra Deep Field in 3D.

All this really does for me in the end is highlight just how bad I am at imagining the sizes and distances involved in the universe. Even knowing it I find myself unable to do any better.

I don’t normally go for the latest viral video. But as a cat lover, I can’t help but share this in an attempt to infect others.
