COSMIC CALCULATOR -- by Steve Nadis
Here's a nifty website you're all dying to visit, or will be dying to visit now that you've heard about it. Called "Ned Wright's Javascript Cosmology Calculator" (http://www.astro.ucla.edu/~wright/CosmoCalc.html), you type in a redshift (z), and it automatically converts that to the age of the universe in gigayears, depending on the assumptions made re. the Hubble constant, omega-mass, and omega-vacuum. In other words, it's indispensable. Upon visiting the site and seeing for yourself what I'm talking about here, you'll wonder how you got through life without it. But now you don't have to. Consider this your "Helpful Hint" for the day.
