years since i graduated, but this is the first time my degree in chemical engineering from rose-hulman institute in terre haute, indiana has been described as liberal and elitist. but that term has become kind of a codeword, more than a literal description. i do understand how my enthusiasm over new technologies can get on people's nerves - my friends frequently roll their eyes as i blither on about new inventions or discoveries. my point was that new technologies like led's, regardless of how much they advance our lives, usually go through a controversial adoption phase, but perhaps that was old news to most of you. by odd coincidence, your email arrived engineer son and engineer daughter-in-law got me. ta-daa! a remote-controlled led light bulb. not only can you turn it on and off, and dim it from with the remote - you can change the colors. how cool is that? technology. amazin. if you have questions or comments, just email those to us or post it on quite the response from viewers. i'll read some of those next week. next up, tis the season for pie. next, andrew mccrea
