Do you think the world is fundamentally dynamical, but you can't find any dynamism in physics, or indeed, science? We recommend you buy our new produce, tense. Not only does this allow you to say a range of useful things, but, if used correctly*, you can use your product to show* that there really is dynamism. 
 
*DISCLAIMER: we make no guarantee that anyone will be conconvinced. Nor are we commited to showing being factive.
