Let’s call it creative destruction, borrowing from a popular term in economics. The idea is that the very essence of capitalism is the destruction of old structures and the building of new ones that inevitably face the same pressures as the structures they replaced. It’s the reason the buggy whip industry fell on hard times.
Aerogels are some of the most fascinating materials on the planet. They were discovered in the 1930s by Stanford University’s Samuel Kistler who proved that he could successfully replace a gel’s liquid with a gas by drying it, thereby creating a substance that was structurally a gel, but without liquid.
Just seven miles south of our OSTI facility in Oak Ridge, Tennessee is a national treasure – the Oak Ridge National Laboratory (ORNL).
Every day we are bombarded with advertisements in every form and format telling us that our lives will be improved if we buy a particular product because it will save us money, reduce our work effort, save us energy, or benefit the environment. We are justifiably skeptical because we know from experience that if something sounds too good to be true, usually it is. Light-emitting diode (LED) lighting is one of the exceptions. LEDs benefits are so powerful that they seem too good to be true; however, they actually do save us money, reduce our work effort, save us energy and benefit our environment.
Light-emitting diode (LED) lighting is a type of solid-state lighting that uses a semiconductor to convert electricity to light. LED lighting products are beginning to appear in a wide variety of home, business, and industrial products such as holiday lighting, replacement bulbs for incandescent lamps, street lighting, outdoor area lighting and indoor ambient lighting.
It is truly wonderful when something comes along that speeds access to science. Such is the case with CrossRef’s linking network for scholarly literature. Anyone that has ever done a literature search prior to 2000 is completely blown away today when they encounter the time saved and the quality of CrossRef’s linking service. I vividly recall my own literature review for my PhD dissertation almost 40 years ago and I want to share my story.
For many long and miserable days and nights for a solid month I practically lived at the University of Maryland’s Engineering and Physical Sciences Library plowing through a massive set of numerous volumes of citation indices looking up keywords related to my dissertation. My topic Secondary deflections and lateral stability of beams was based on my research at the U.S. Naval Research Laboratory.
