Fourier Analysis is a mathematical tool which can do a number of things: separate out signals from noise; help identify patterns or trends in data; filter out all unwanted data and focus on a single signal; use approximations to make generalizations; make approximations of real world signals (think electronic music); combine harmonics to get a stronger signal. That's what I'll be trying to do here!! Won't you join me with your comments?

Google Fun!

Google Earth now has an upgrade which is literally "out of this world" . With this upgrade you can now cruise the heaven from your home/desktop computer. Now supernovas, galaxies and all sort of celestial phenomena are only a mouse click away.

The upgrade is ‘Sky in Google Earth’, and it
can be downloaded free of charge with the newest version of Google Earth. Now in just a few seconds, anyone can view over 120 of the most popular Hubble images. It is fairly simple to operate with drop-down menus and zoom features that are typical of Google Earth.

But this blog is my usual Saturday Silliness, so here is a bit of silly Google Fun. In addition to their Google Earth, there is also a website Google Moon. This is also a really cool website with the landing sites of all the Apollo missions indicated. Any of these features can be clicked on and viewed up-close. The really fun part (show this to your kids!) is when you choose to zoom in really close to see what the moon looks like at the highest definition!

Happy Weekend!!

I want your brain. Just for a night of looking at the stars. You are so wicked smart.

Very cool. I looove Google Earth. I've got to look at the others.

Ah SMID, I would LOVE to have the brain you think I have!! Anyone can look! As my Momma says, "A cat can look at a queen." But I find looking at the wonders of nature, cosmic or otherwise, does have brain-expanding powers. I'm just so science oriented that I "think geek". Really I am (occasionally) a more well-rounded person.

Leslie, you're gonna loooove these as well! Just make sure you have someone who will pull you up for air. I have spent hours/days on these sites!

How fun! I can't wait to try all this!

Have you tried Microsoft's Live Search yet? It's another satellite map program with an additional 3-D perspective so you can tilt your view and circle around the subject area. And, it appears the 2-D perspective has an even higher resolution that Google Earth somehow. It's pretty amazing. Here's the link:
