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?

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!
