Welcome! 欢迎!

Well, hello there readers! If you are currently a high school student, I'm sure you'll be able to understand the weird turn life has made in the past few years. What happened to having no responsibilities? What happened to that acceptable nonchalant attitude towards life? Now, every second of life is filled with something to... Continue Reading →

Chemical Kinematics Study Guide

Definitions: Rate of reaction: the speed at which reactants are used up or products are formed, or the change in concentration of reactants or products per unit time. Collision theory: chemical reactions occur because particles collide; the particles have more than a certain minimum amount of energy, and they collide with the right orientations. Activation...

#8 Schrödinger’s Cat

In 1935, Schrödinger published a paper, titled "The Present Situation in Quantum Mechanics", Chapter 5 of which described the infamous Schrödinger's Cat thought experiment. Quantum theory states that before measurement, we cannot be sure of a particle’s status. Remember the particle-spin thought experiment Einstein put out? (If not, read about it here) Bohr had stated... Continue Reading →

#6 The Uncertainty Principle

February 1927. For Heisenberg, life was a nightmare. Schrödinger's equation was rapidly gaining popularity; even his mentor Bohr seemed to prefer Schrödinger's model more than his. Now, only Heisenberg, Pauli, Jordan, and Dirac remained supporters of particle theory. Pxq≠qxp. Heisenberg continued to muse on that puzzle. What does pxq represent? It means that you measure...

#5: Schrödinger’s Equation

Erwin Schrödinger was already a famed professor in Switzerland when young Heisenberg brought out his matrix theory. Planck found that energy is quantized in an atom. To explain this, Bohr came up with the concept of “energy levels”, Heisenberg used a matrix to prove it, and Schrodinger decided that this complexity was not necessary. In... Continue Reading →

#4: Werner Heisenberg’s Matrix Mechanics

In Copenhagen, Werner Heisenberg worked closely with Niels Bohr. 1925, Heisenberg returned to Göttingen from Copenhagen, and started tackling the problem of the hydrogen line spectrum. By that time, he had realized that electrons did not just move on orbits, but jumped in between them, releasing energy in the process. Calculations using traditional maths, however,...
