RULLES FOR CLACULATING WITH SIGNIFICANT DIGITS.

The rules for determining significant digits.

In quantum mechanics, the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, such as position x and momentum p, can be known simultaneously.

Mr. Swords reviews how scientists compile data for research and study purposes.

Mr. Swords teaches how investigation begins with inquiry and observation. Qualitative and Quantitative observations are also discussed.
