## Uncertainty Principle? Wave Nature of Matter

Articles, Blog 0 CommentsUncertainty principle is one of the most popular concepts of the quantum mechanics. Let me introduce a misconception about the uncertainty principle. When you are to see matter, say a particle, you need a light to be scattered off. You observe the scattered light to get an information about the particle. But the particle is

## What is quantum mechanics really all about?

Articles, Blog 100 CommentsFor the most part, physics is a pretty straightforward discipline. While the math might be complicated, physics is often about quantifying such things as “what goes up, must come down” and “don’t play chicken with a train.” Statements like those are intuitive and pretty much everyone can get their head around them. But, over the

## Schrodinger’s Equation

Articles, Blog 0 CommentsAccording to Quantum Mechanics, all particles in the universe are described by what we call a wave function, and quantum wave functions are described by Schrodinger’s Equation. Although the behavior of all subatomic particles is inherently probabilistic, Schrodinger’s equation does not itself contain any probabilities. The probability of every possible observation is determined by the

## What Is Light?

Articles, Blog 100 CommentsLight, is the connection between us and the universe. Through light, we could experience distant stars and look back at the beginning of existence itself. But, what is light? In a nutshell Light, is the smallest quantity of energy that can be transported A photon, an elementary particle without a real size That can’t be

## Basic Geophysics: Reflection & Refraction

Articles, Blog 1 CommentThe reflection and refraction of light influence our everyday life. Here you can see a laser beam that passes through a plexiglas object. The way these optical waves change direction when they pass into another propagation medium is equal to that of seismic waves. The reflection and refraction of seismic waves allows us to explore

## Basic Geophysics: The Seismic Slowness

Articles, Blog 0 CommentsThe excitation of seismic waves using hammer strikes is a simple method of exploring what is underground. Shown here on the X-axis is the distance from the source, and plotted on the Y-axis is the time after the hammer strike. The further away the seismometer or geophone is from the source of vibrations, the later

## Science of Watchmen

Articles, Blog 100 CommentsHi, I’m Jim Kakalios I’m a physics professor at the University of Minnesota, and I was asked to do some science consulting for the Warner Brothers film: The Watchmen. In Watchmen, Dr. Manhattan has amazing superpowers. He can teleport from one location to the other, he can split himself into multiple copies, he seems to
