The document contains a collection of quotes and maxims related to engineering design and analysis. Some of the key ideas expressed are:
- Design is an iterative process that requires multiple iterations to reach perfection or a good solution.
- Estimates and initial analyses may contain errors, and one should not assume their correctness without validation.
- There are usually multiple wrong solutions to a problem, and the best solution is not always obvious or single. Iteration and reevaluation of assumptions is important.
- It is sometimes better to start over with a new approach than persist with a flawed plan or analysis. Capabilities, not just requirements, should drive engineering decisions.

2. A designer knows
that he has
achieved
perfection not
when there is
nothing left to
add, but when
there is nothing
left to take away.
3. Engineering is done with numbers.
Analysis without numbers is only an opinion.
4. Design is an
iterative process.
The necessary
number of
iterations is one
more than the
number you have
currently done.
This is true at any
point in time.
5. The odds are greatly against
you being immensely
smarter than everyone else
in the field. If your analysis
says your terminal velocity
is twice the speed of light,
you may have invented
warp drive, but the chances
are a lot better that you've
screwed up.
6. The fact that an
analysis appears in
print has no
relationship to the
likelihood of its
being correct.
7. There
is
never
a
single
right
solution.
There
are
always
multiple
wrong
ones,
though.
