What Web sitesoffer a way to convert units of measurement?
The conversion of units of measurement are necessary, especially between same types
of units (such as feet to inches) or between Standard and metric units (such as miles
to kilometers). There are numerous sites on the World Wide Web to make such con-
versions. In most cases, just type in the number you want converted, hit the return
button, and a list of the converted numbers are displayed. Among these sites are:
- http://www.onlineconversion.com
- http://www.convert-me.com/en/
- http://www.sciencemadesimple.com/conversions.html
- http://www.convertit.com/Go/ConvertIt/
What Web sitesoffer links to the history of mathematics?
The history of mathematics is an extensive topic—too much to cover in this text.
Some of the best sites to explore its history are as follows:
British Society for the History of Mathematics(http://www.dcs.warwick.ac.uk/
bshm/)—If you want “one stop shopping” in your search for the history of mathemat-
ics, go to this comprehensive link site. This organization promotes research into the
history of mathematics at both professional and amateur levels, as well as the use of
that history in education.
Clark University’s Department of Mathematics and Computer Science(http://
aleph0.clarku.edu/~djoyce/mathhist/mathhist.html).
Math Archives—History of Mathematics(http://archives.math.utk.edu/topics/
history.html)—A mathematical historical archive with other mathematical topics, too.
MacTutor History of Mathematics(http://www-groups.dcs.st-and.ac.uk/~history/)
—This archive is from the School of Mathematics and Statistics at the University of
St. Andrews Scotland. It is an extensive resource on the history of mathematics from
ancient times to the present.
What are some Web sitesdevoted to recreational math?
There are literally hundreds, if not thousands, of recreational math Web sites. The fol-
lowing is just a taste of what’s out there:
