When budding scientists in elementary, middle and high school need information about chemistry, they have a myriad of sources online. One very popular source turns out to be the Lab’s periodic table site, linked to the Chemistry (C) Division’s external home page. How popular is it? Since May 2000 the site has logged nearly two million hits. The site is maintained and updated by computer technician Nick Degidio and staff member Moses Attrep both of Isotope and Nuclear Chemistry (C-INC). “We average about 30,000 hits a month,” said Degidio. “And that number doubles around finals, term papers and midterm exam time. Its popularity is pretty surprising.”
High definition television is coming to a screen near you — at least we hope so. For some television viewers the system is already in place and working well. For many more consumers, however, the technology may be a bit later in coming.

Add to that Dolby digital sound with six separate audio tracks for detailed and realistic surround sound and you’ll probably agree HDTV is a better way to see television. Many people involved in the transition are beginning to fear that when the federally mandated time comes in 2006 to convert broadcast formats, a large per- centage of the population will not be ready
