My son found this “confusing”. I found it amazing and creative. And try to get that song out of your head.

THe fertilizer comes primarily from natural gas, which of course is a non-renewable energy source. Further, too much nitrogen is being used. It runs off and kills streams, rivers, lakes, and the ocean …

Excel User Tip: Creating a database table from a summary table

When Microsoft first included Pivot Tables in Microsoft Excel (early 1990’s as I recall), it took me a little bit of time to get my head around what they were and what they were good for. Once in head, I recognised how powerful they are.

NASA – Stellar Rubble May Be Planetary Building Blocks

When I was a kid I consumed “NASA Facts”, a public relations newspaper sent out to promote NASA and their achievements. For nostalgia reasons, I wish I hadn’t thrown them all away. Meantime, NASA now has computers and the internet to do the same things. See this link where there is a supurb animation of an exploding star (with a poor planet near by), resulting in a pulsar with a surrounding disk of rubble. The Hubble telescope has seen these same structures.
