Solving quadratic equation and factoring.
Chris Smith demonstrates the behaviour of a rheopectic fluid, i.e., one whose viscosity increases with the strain rate. The fluid can easily be stirred at slow shear rates, but resists as the shear rate is increased. The jagged molecules are lubricated by water at slow shear rates, but lock against each other at higher strain…

Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.
