An Introduction to Quantum Theory


A university student pursuing coursework in linguistics and literature, Matt Kafker also enjoys learning about physics, math, and computer science. Matt Kafker is currently taking classes in differential equations, special relativity, and quantum physics. 

At the most basic level, quantum theory deals with our physical understanding of things that are very small: atoms, subatomic particles, and waves. As the particle in question becomes smaller and smaller, the way we understand it changes fundamentally. Energy and mass appear to behave quite differently at macroscopic levels, but that distinction becomes significantly less clear with small particles. In practice, quantum physics must consider the properties of both particles and waves at the subatomic level. 

From a mathematical perspective, quantum physics relies on probability functions when determining the outcomes of an experiment. Simply put, it is impossible to predict with 100 percent certainty the outcome of an experiment within a quantum system. In chemistry, the position of an electron cannot be determined with precision; it can only be expressed as a probabilistic wave function. This leads to theoretical concepts such as the notion that a particle occupies more than one state at a time, as evidenced by thought experiments such as the famous Schrodinger’s cat.

Steven Pinker - Short Biography of the Experimental Psychologist


An accomplished university student, Matt Kafker currently studies physics, math, and computer science. Enthusiastic about the natural sciences, Matt Kafker enjoys reading books by Richard Dawkins, Richard Feynman, and Steven Pinker

Pinker is a Johnstone Family Professor at Harvard University’s Department of Psychology. He was born in 1954 in Montreal, Canada. He studied experimental psychology at McGill University before moving to the United States. In 1979, he earned a doctorate from Harvard and went on to undertake a postdoctoral fellowship at MIT. He spent many years serving in the psychology departments of various institutions including MIT, Stanford, and the University of California, Santa Barbara, before settling in at Harvard. 

An experimental psychologist, Pinker is one of the most well-known writers on the correlation between language, the human mind, and human behavior. Some of his most popular books include The Language Instinct, How the Mind Works, The Sense of Style, The Blank Slate, and Words and Rules: The Ingredients of Language. 

A regular contributor to the New York Times, Pinker has won several prizes from institutions such as the Cognitive Neuroscience Society, the American Psychological Association, and the National Academy of Sciences. He has been named among Time Magazine’s 100 Most Influential People in the World and Foreign Policy’s 100 Global Thinkers.
