Re:SLIDE RULE (Score 1)

I agree. Slide rules are the perfect tool for high school and undergrad physics classes:

1. Most physics problems don't require the extra digits of precision offered by electronic calculators.

2. Slide rules force students to decide what the magnitude of the answer should be.

Basic slide rule use should be covered in Week 1 and electronic calculators banned. Slide rules got us to the moon and back; they can certainly serve for Physics 101.
