13. Lecture 1-Nats 10113 Literacy Requirements Although the writing requirement for this course is negligible, there is a science literacy requirement. This means that we: Use scientific notation for writing numbers (especially rather large or small ones). Specify units of physical quantities (e.g. meters for elevation, etc.). Attempt to quantify physical relationships.
