Welcome to Serendip's Exchange! Glad you stopped by.
Looking for “the answer” to a question? There are plenty of websites out there which will tell you what to think. Serendip instead aims at helping you to think for yourself, and in the process of discovery to formulate new questions and new explorations.
Nothing on Serendip is "authoritative", but there is lots here that you can learn from and contribute to. See (and click on) the material below and to the right for recently added discussions. Click here for publishing guidelines.

The Physics Classroom Tutorial is an online physics tutorial written for high school physics students. The tutorial was originally developed for physics students at Glenbrook South High School in Glenview, Illinois.
The Tutorial covers basic physics topics using informative graphics and an easy-to-understand language. Each unit is broken up into lessons and sub-lessons. A lesson resembles the type and extent of coverage given to that physics topic in class. The sub-lessons are accompanied by Check Your Understanding sections, providing an opportunity to assess one's understanding of the lesson material. The tutorial, when combined with other resources at this site provides a student of physics a great opportunity to learn and to test their understanding.
We are able to view all entities, from the microworld to the universe, from a single perspective. By setting them up against a scale, we are able to compare and understand things which cannot be physically compared.
Today, using the electron microscope and astronomical telescope, we can see the objects which we have not been aware of its existence before. Are you able to fathom, or even roughly grasp, these sizes?
See our Universcale and experience the sizes of various objects.
