Since much of SI is based on physics and mathematics, physics teachers have the background to teach SI. We present this review and summary in a series of SI notes in order to help teachers answer many questions about the SI that often are, or should be, asked (for example, in workshops for teachers). SI should not be considered a jargon to set science apart from everyday life but as a tool to make everyday measurements in all fields easier and more informative. It will be assumed that the reader has some general background knowledge of SI.1 A review and update of SI is timely now because the official United States SI document has just been updated.2 |
