I wrote more than 50 articles for eHow.com in 2011, covering topics varying widely, from “What to Do With Pumpkins After Carving?” to “The Phases of Neptune.”
After a major overhaul of eHow.com’s content several years ago, many of those articles are no longer available, or have been moved to other properties, like Sciencing.com. Here are a few examples of the ones that are still out there:
PVC, or polyvinyl chloride, was developed by scientist Waldo Semon back in the 1920’s. It gained a more mainstream following in the 1950’s and 60’s and, since then, has been used in a variety of products, from piping to apparel. Today, crafters can use PVC fabric to create all sorts of unique items that were previously made from less durable cloths and materials.
In the early 1900s, Norwegian meteorologists developed the first models for the life cycle of mid-latitude cyclones. Also known as wave cyclones, extra-tropical cyclones or baroclinic storms, mid-latitude cyclones tend to form between 30 degrees and 50 degrees of latitude during the winter months and develop into massive, spiraling storms that can grow up to approximately 1,000 miles wide.
