Across 2. Using the water works analogy, this electrical property is the equivalent to water flowing in a pipe 4. To trade current for voltage (or to turn a robot into an airplane), you need one of these 7. Our assumption about light and shadows tells us that the usually come from this direction 9. The "check valve" of electronics 12. Your brain can guess that the Grand Canyon is really deep by using this type of angle 14. Keeps your electrodiagnostic patients from getting a nasty shock 15. When we compare our own head motion with the motion of something closer to something farther away to determine distance, it is called this 17. This part of the near triad gives us a binocular depth cue 18. This effect may explain why the moon looks bigger on the horizon 19. A high-voltage version of this can electrocute you if you open up a TV set, even if it's unplugged 20. This visual illusion of lines that appear to be different lengths is probably explained by our experience with corners

Down 1. How small tiles look at the far end of a long hallway is an example of judging depth by this monocular cue 2. In Los Angeles or any big city, distance can be judged by this principle because of intervening smog 3. This visual illusion may be the basis of the corridor or hallway illusion 5. This creature has two-and-a-half times the voltage of an ERG, and over six times the wattage of the human body 6. Can be used to lower your blood pressure and diminish migraine headaches without medicine 8. Resistance in a live human cell, should be 5 kohms or less for electrodiagnostics 10. Uses Gaussian principles to generate an electric field with a flowing current 11. The variable valve of electronics, on which microchips are based 13. Software that plots voltage changes over time 16. When accommodation plays little or no role, we judge distance from this effect

The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
