“Technology is the use of increasingly accurate, self-evident, and reproducible information to replace energy and matter.

The benefit of technology is NOT in what it lets people accomplish, but in how it improves the character of people.”


The evolution of technology - 1862 vision testing standards are no longer adequate






“Technology is our word for stuff we don’t understand.”

- Douglas Adams


Arthur C. Clarke’s Three Laws:


          1.  “When a distinguished but elderly scientist states that something is possible, he is almost certainly right. 

            When he states that something is impossible, he is very probably wrong.


          2.  The only way of discovering the limits of the possible is to venture a little way past them into the impossible.


          3.  Any sufficiently advanced technology is indistinguishable from magic.”

- Arthur C. Clarke’s Three Laws


         4.  When technology becomes sufficiently obsolete, it becomes an art form.

- Allan’s Corollary


“It is important that students bring a certain ragamuffin, barefoot irreverence to their studies;

they are not here to worship what is known, but to question it.” 
- Jacob Bronowski, “The Ascent of Man


The first rule of science is to challenge your own assumptions.

From the “Gates of Repentance” Prayer Book: 

“Just as the hand, held before the eye, can hide the tallest mountain, so the routine of everyday life can keep us from seeing the vast radiance and the secret wonders that fill the world.”

                        - Chasidic, 18th Century


The Scientists’ Prayer:
