Discover the fundamental nature of matter; everything is made of atoms. The atomic theory is brought to life in "Atoms in Motion" -- this book is a guide to fully interactive atomistic simulation that uses sophisticated Molecular Dynamics (MD) algorithms to perform computational chemistry calculations right on your iPad. Such computations reveal the motions of atoms as they attract, repel, and collide with one another.

Fun for all ages -- in this simulation you control the atoms! With the tap of the finger you can add, delete, or highlight atoms within the simulation. With a gentle touch you can move, place, or throw atoms. With the swipe of a finger you can control the temperature and explore the states-of-matter (solids, liquids, and gases). Discover the physics behind the ideal gas laws, and perform your own experiments by changing the volume, the number of atoms in the simulation, or the temperature.

This Molecular Dynamics (MD) simulation includes realistic interatomic potentials of four noble gas elements: Helium, Neon, Argon, and Krypton (the van der Waals forces are computed using a Lennard-Jones 6-12 potential). The MD simulation continuously computes the pressure, and dynamically plots the pressure versus temperature, volume, or the number of atoms. Users can vary the temperature from near absolute zero to over 500K, and add up to 1,000 atoms to the simulation.

Enjoy the Atoms!


  • Great intro/refresher for basic chem

    By Tatt2dKitty
    Downloaded this expecting to read a few pages and delete it like I've done with many others, instead I was very pleasantly surprised with the information. I'd use this for teaching older children and those looking to refresh their college intro chem from many years ago (i.e. me). Good combo of verbiage and interactive pictures with a very clean and uncluttered layout. More please!!
