Having car troubles? Learn more about repairs in two of our databases. Both contain step by step instructions for doing basic and advanced repairs. If you aren’t up to doing the repairs yourself, both also include a labor estimating tool, so you can find out how many hours a repair will take at the manufacturer or at an auto mechanic. Both also include helpful information on bulletins and recalls issued from the manufacturer.

Have you noticed the increasing number of LEDs around? You may not realize it but they are everywhere now – your smartphone, your television and your white LED light bulbs. Do you want to know more about them?

One of the leading researchers in solid state lighting is Shuji Nakamura, the scientist who won the 2014 Nobel Prize for developing a method to simply and cheaply produce blue LEDs. Mr. Nakamura himself has written a technical article that provides an overview to the topic in the database Access Science. It is titled “Blue Lasers”. Another article titled “Blue LEDs Win Nobel Prize in Physics” written by Grant Wood, tells the tale of the invention of blue light emitting diodes. The Upper Arlington Public Library has a subscription to the database that has both articles. You may click on the titles above to read the articles and you may click on the logo below to search other science-related topics.
