Fundamental Ideas and General Philosophies of
Numerical Analysis and Methods
(that I find interesting)
- Replace a general function by a simpler function, and
perform the computation exactly for the simpler function.
- Given an expression in terms of something simple plus a
remainder, generate a numerical approximation by dropping
the remainder term. (and adjusting the notation, perhaps)
- This is where we introduce Truncation Error
- Use computable estimates of quantities that cannot easily
be computed.
These thoughts taken from An Introduction to Numerical Methods
and Analysis, by James F. Epperson, John-Wiley and Sons, 2002.
When attaining bounds for error analysis:
- The bound itself is usually the least important part of
an error analysis. The main object of such an analysis is to
expose the potential instabilities, if any, of an algorithm so
that, from the insight thus obtained, one may be led to improved
algorithms.
This thought taken from Numerical Linear Algebra and
Optimization, by P. Gill, W. Murray and M. Wright, Addison
Wesley, 1991. The authors credit this remark to J.H. Wilkinson
-famous (in certain circles any way) Numerical Analyst.
- Finality is not attainable in science.
This thought taken from Relaxation Methods in Theoretical
Physics, by R.V. Southwell, Oxford at the Clarendon Press, 1956.
- Mathematics is the Queen of Science, and Arithmetic the
Queen of Mathematics - Carl Friedrich Gauss (famous
mathematical BIG DOGG)
This thought given to me by Dr. Jennie Luebeck right here in
our own department.
- Nobody likes a math geek, Scully.
This thought taken from Agent Fox Mulder
, X-Files Episode, circa the Y2K episode.
- Just because you CAN fix something doesn't mean
that you HAVE to.
This thought taken from Christine Latulippe
, over tea and a cookie at the Leaf and Bean.
