The Molecular Weight Calculator calculates a molecule's molecular weight (or formula weight), and the molecule's percent composition, displaying the results for up to 20 compounds simultaneously. The program also supports amino acids, including predicting the theoretical b and y or c and z ions that could be created by MS/MS dissociation. The program is available for Windows (XP/7/8).
For anyone who has tried to solve the 3x3x3 or the 2x2x2 Rubik's cube or the Pyramix (Pyramid) and failed, these pages contain easy to follow instructions, including pictures. Also available are instructions for solving the 5x5x5 cube (aka the professor cube) and the Square 1.
These instructions only involve a handful of moves and are thus fairly easy to memorize. Once you are proficient with the moves, you will be able to solve a scrambled cube in 3 to 5 minutes. Thus, these are not speed cubing moves. If you wish to learn more about speed cubing, please browse the List of Cube Links or visit Speedcubing.com.
