Science should be taught to everyone so that everyone
can appreciate the complexity and beauty of nature.
Science should be taught to everyone because great
scientists can become great only if they become scientists
Science should be taught to everyone because
understanding science is the key to understanding
technology. And technology has become a force in society
which, if we are not careful, will control our future.
Doing challenging work of any kind trains the brain.
Studying science provides students with an opportunity to
think deeply about complex systems. Specific skills and
concepts may or may not have long-term application but the
ability to think critically and synthesize complex
information is universally applicable.
Not every student in an art class becomes an artist. Not
every student in a science class becomes a scientist. But
everyone should learn to understand the beautiful and
everyone should learn to understand the world around them.
Science, at its best, is doubt instilled in a person as a
virtue. Certainty is stagnation: the human imagination is
no match for the imagination of nature. Nature does not
give up her secrets easily. Critical thinking and careful
comparison are essential toward building the constantly
improving models built by the methods of science.
Mr. Keller’s Motto
It’s not about what you did, it’s about what you learned.
Correct answers matter less than critical thinking. If you
think carefully, and work hard, correct answers will come.
The important thing is the thinking. If you think carefully
and reflect on your work you will see for yourself whether
your answers are correct or not. I use an acronym to summarize my thinking here: FIO. If you think about it for a few minutes, and you want to know what this stands for, you will figure it out.
Before printing turn off the optional header and footer
information. Also, make the left margin 0.75 in (1.9 cm)
and the other margins 0.5 in (1.3 cm) so that the page
breaks I built into the pages work as intended. Use only
Internet Explorer to print as Netscape and Firefox both
implement the page code a bit differently and I haven't
optimized the pages for those browsers. My apologies if you
are using a Mac: I cannot guarantee that you will be able
to print these pages as I intended.
Some of the files are PDFs and you need the Acrobat Reader
available from Adobe. Some files are
also MS Word 97 or RTF documents, which just about anyone
should be able to view. If you have trouble, try going to
download the Word Viewer.

Science and Pseudoscience
Inspect every piece of pseudoscience and you will find a
security blanket, a thumb to suck, a skirt to hold. What have
we to offer in exchange? Uncertainty! Insecurity!
It always takes longer than you think it’s going to
take, even when you take into account Hofstadter’s
It ain’t what you don’t know that gets you in
trouble. It’s what you know for sure that just
Understanding the Universe
“The effort to understand the universe is one of the
very few things that lifts human life a little above the
level of farce, and gives it some of the grace of
“Magic, as practiced by performing magicians, is the
art of making people see things that didn’t happen and
miss seeing what did. Teaching science is the art of making
students see things they never suspected to exist and
recognize when they seem to see things that do not
