The Astronomy Learner

Typesetting mathematics in HTML is time-consuming to say the least. The LaTeX language math-mode allows us to typeset math in a much simpler way. Our interface to this system is MathJax. Setting up MathJax on Blogger can be a daunting task. While there are many ways to implement MathJax on the internet. You will want to put the following code into the Blogger template you choose to use. Paste the code right below the head tag in the template. To do this go to the Template Editor and edit the HTML ( Template >> Edit HTML ) The simplest method is to just use the paste the following code into the template: <script src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML" type="text/javascript"></script> After pasting, make sure none of the text or symbols have changed. If it is not working, sometimes it is a good idea to paste it into a plain-text text editor (like EditPad ). The config=Tex-AMS-MML-HTMLorMML tell

1. Carefully read the instructions and problem description. 2. Draw a picture of the physical situation. In astronomy, this often involves circles and lines. Make your drawing large enough to label clearly in the next step. Keep your lines straight. Slow down . It’s not a race to the finish line. If you'd like to have fun and draw cartoon characters or artistic scenes, this is fine. Indeed, it’s encouraged, especially if it helps you slow down. Just avoid obfuscating your drawing. 3. Label your drawing with the key physical variables. For example, distances should be labeled with \(D\), \(d\), \(L\),\(a\) (semimajor axis), \(R\), \(r\), etc. Use appropriate subscripts. Use these symbols consistently throughout the problem-solving process. 4. To the side of your drawing, list your known and unknown variables. An example of a known value: $$ R_\oplus = 6.4 \times 10^8 {\rm cm} $$ An unknown value: $$M_{M} = ?\ g$$ 5. Identify and write down an equation that your intuiti
