that will assist in finding available information.
between different sets of units are a common problem because of historic
procedures and the slow progress toward standardization. The failure of
the US to adopt SI
(System international) makes the North American scene awkward because Canada and Mexico use SI or Metric as it
is often referred to. The scientific community and some manufacturers in
- Many applications require estimates of
the weights and volume of materials. Only a small
set is included in the table provided. It should be expanded to include
the materials of interest.
- The Windows operating system comes with
a built in calculator that can be started
from the tools page. While this calculator is not as portable as a hand
calculator it is convenient for casual calculations while performing other
operations, such as preparing text or filling out forms. A simple four
function, or scientific versions are available. For engineering, or time
value calculations the scientific version is more useful. It allows
raising quantities to powers. It is also useful to have a shortcut to the
calculator also on your desktop as well as being able to implement from
the tools page or the Windows menu system.

expression. The variables are restricted to singletons. A library of
expressions can be developed and reused using 'copy' and 'paste'
facilities of the OS.
- There are several traditional compound interest functions that are used for time
value and engineering economy calculations. A fairly complete set is
available as interactive routines. They are linked to the TVY section of NUNET.
- .Shortcuts for starting Lotus
123 and Works Speadsheet
are provided. Using these spread sheet depends on having them installed on
your computer and the shortcut files to start them. You may have other spread sheets
available and or the path may not suit your setup. Modify the .bat files
to suit your setup.
- Access to APL and
J is provided for development of more
elaborate models than can be handled by the calculators listed above.
These are high level array handling languages and can be learned if your
application requires. To use either of these they must be installed on
your computer. Note if you are using one of the APL workspaces you should
have an APL character set available on your computer. I use the 9x11
character size and this produces the APL display in a window that fits on
my screen. You can use the whole display by loading an APL work space and
the using [Alt Enter] to switch from a window to full screen. Note: [Alt
Enter] toggles back and forth from window to full screen to Window.
