QUANTUM PHYSICS SHOULD LOOK AS HARD AS IT IS.
==================================
Perturbation theory is a mathematical tool for approximating the energetic response of weakly disturbed systems. The basic idea is to take a “simple” system that you can solve on paper, such as an atom, and to “perturb” it by introducing an energy disturbance, say, by having the atom interact with a particle of light. Solving this outright would be impossible, but as long as the perturbation is small, it is possible to expand the new answer out in terms of its known energy states in order to estimate how they change.
==================================
Left sleeve features perturbed Shrodinger’s Equation.
Right sleeve features power series expansion of the perturbed quantum eigenstate solution.
100% cotton face
65% ring-spun cotton, 35% polyester
Front pouch pocket
Self-fabric patch on the back
Matching flat drawstrings
3-panel hood
Graphics are digitally printed (DTG) onto the black hoodie on a made-to-order basis. This helps prevent overproduction and waste. They usually ship out within a week! I noticed the sizes run a bit small, so I would go a size larger than you normally wear if you want a nice big hoodie that is cozy and showcases your enthusiasm for approximation methods for computing quantum energy eigenstates. For reference, a medium is shown in the pictures, and I am ~5’9”.
