As a scientist of any capacity, knowing the elements will always be a useful tool in your toolbelt. The NoFoldPT app allows you to store this information in your pocket, without one fold of paper. The app provides a periodic table with an array of information, and also provides flash cards to help learn the names and numbers of the elements, an important first step to familiarity with the physical world. Placing this information in your pocket to drill in downtime can be a very useful tool. This information is so critical and fundamental that we provide it free of charge. Good luck.
