Quantum mechanics forbids us from measuring the universe beyond a certain level of precision. But that doesn’t stop us from trying. And in some cases succeeding, by squeezing the Heisenberg uncertainty principle to its breaking point.

After a long day working on the particle accelerator, you and your friends head to the arcade to unwind. The lights go out for a second, and when they come back, there before you gleams a foosball table. Always game, you insert your...

It’s one of the biggest mysteries in science. It makes up the majority of the universe. What is dark energy? What is dark energy made of? What is quintessence? Is Dark energy the cosmological constant?...

When Ernest Rutherford realized that atoms have a heavy nucleus, he hypothesized that the way the moon orbits earth is the same as the way an electron orbits the nucleus of atoms. We now know an atom would...

What is this mysterious quantum tunneling effect, where does it come from? And why is it one of the most important phenomena in physics?

When the nucleus was discovered by Rutherford, it became clear the classical world was not reality, because according to classical electromagnetism, the electron should collapse to the proton. This problem was...

Heisenbergs uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

The act of measurement in quantum mechanics causes "collapse of the wavefunction". Here, I explain what is meant by measurement in the discipline of quantum mechanics.<br/>

Heisenberg’s uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

Here, I explain the basic idea underlying Heisenberg's Uncertainty Principle; also 1 simple example is worked.<br/>

In this video, I do one example for determining whether or not two quantum operators commute [position & momentum (x-dir)]. Previous example (Example #1)
