At first, our site consisted of 10 "non-interactive" pages
which would get very few hits. Adding interactive
calculators, increased traffic dramatically !!!

Are you tired of paying big money for software? Well there are some folks who believe in free, open-source software. To read more about this, please go to the Free Software Foundation 
We have received several requests for a TIME converter that converts different world times (as opposed to calculating seconds in a year, etc.). So, how about a link to what we consider to be the BEST World Time Clock on the Internet. As you know, 1728 is very reluctant to put ANY links on this webpage, so take it from us, this site is FANTASTIC !!! But don't take our word for it, go to the World Clock: 
The employees at 1728 have earned several certificates from Brainbench.com
Bad Astronomy is actually a website for "good" astronomy facts, links, news and so on. So how does it earn its "bad" name? By exposing the mistakes about astronomy reported in newspapers, television and movies. Such sources unfortunately are rife with mistakes about astronomy. Luckily, people such as Phil Plait put the media back on the proper astronomical track. This is a top-notch site authored by a well-informed, well-credentialled astronomer. Please pay a visit to:
A tremendous website for extremely precise scientific data is The
National Institute of Standards and Technology (formerly the National Bureau
of Standards). This is a highly professional, scientific website that will
meet the needs of even the most exacting scientist or web surfer. NIST is a
United States government agency and so you know the website and its
content can be regarded as impeccable.
