7 Scientific Mnemonic Devices To Make Studying Easier

Science, technology, engineering and math (STEM) classes are challenging and often require a lot of study time to memorize the many formulas and concepts. But once you become familiar with them, the pieces fall into place. One method for remembering a large quantity of information is the use of mnemonic devices — memory tools that aid in creating shortcuts and recalling information easily. It could be anything from acronyms, a tune, or forming a silly yet memorable sentence where the the first letter of a word represents another idea. We put together a list of seven mnemonic devices from various STEM subjects you're likely to encounter. And, of course, have fun creating your own!
