Schrödinger's cat: A thought experiment in quantum mechanics - Chad Orzel. Here’s are more TED-Ed Lessons by the same educator: Particles and waves: The central mystery of quantum mechanics and What is the Heisenberg Uncertainty Principle?

Schrödinger's cat: A thought experiment in quantum mechanics - Chad Orzel

Schrödinger’s Cat is a very fertile subject for discussion, and has also been discussed in this lesson from Josh Samani. Here’s more about the thought experiment described briefly by Minute Physics. Go to the Sixty Symbols video and learn much more detail about Schrodinger’s Cat. For a humorous look at this cat experiment, venture to this site for a simulation. Erwin Schrödinger shared the 1933 Nobel Prize in Physics with Paul Dirac for his discovery of the equation that governs the behavior of quantum particles. Schrödinger had wide-ranging interests in science and philosophy, and delivered a famous lecture on the physics of biology at Trinity College in 1943. One of the issues associated with Schrödinger’s cat thought experiment is exactly how an experiment arrives at the single final state that we observe.

A brief history of melancholy - Courtney Stephens. Robert Burton attempted to gather the totality of human thinking on sadness and melancholy in his 1621 book The Anatomy of Melancholy.

A brief history of melancholy - Courtney Stephens

Similar to the approach in this video, Burton gathered widely in thinking about the subject. This includes quotes from thinkers and literature, anatomical drawings, and Burton’s own meditations. Check this page of quotes by Robert Burton for more insight into his thinking! Burton was fascinated by the ancient humoral medical system, from which the word melancholy is derived: Black bile = melancholia. Those with an excess of this humor were expected to be serious and despondent. Burton’s quote “he who increaseth wisdom increaseth sorrow,” (which some have suggested was Burton being ironic) has become a cliché that artists and writers tend to attribute to depression and other challenging emotions. In the Buddhist worldview, suffering has always been regarded as part of the fundamental fabric of reality. Sooner or later, everyone gets the blues. Einstein's miracle year - Larry Lagerstrom. If you want to find out more about the trials and tribulations of the young Einstein and the triumph of his miracle year (including the fact that he also published a fifth significant paper that year!)

Why not take a free online course: “Understanding Einstein: The Special Theory of Relativity?” The course is currently not open for earning a certificate, but all the videos and learning resources are available to view for self-study. Get started, who knows what you may discover?

There are hundreds of books on Einstein. What can Schrödinger's cat teach us about quantum mechanics? - Josh Samani. Quantum entanglement was first studied in 1935, in a famous paper by Albert Einstein, Boris Podolsky, and Nathan Rosen. These scientists collectively have come to be known as EPR, an acronym that derives from the first letter of each of their last names.In their paper, the authors considered a certain instance of entanglement that has since come to be known as the EPR paradox or the EPR experiment.

The purpose of their paper was to use the paradox to demonstrate that quantum mechanics could not provide a complete description of reality. The term “entanglement” was not coined by EPR.Instead, it was first used by Erwin Schrodinger, one of the fathers of quantum mechanics, in a letter to Albert Einstein discussing the EPR experiment. What is the Heisenberg Uncertainty Principle? - Chad Orzel. Minute Physics offers a shorter version of the Uncertainty Principle argument with cartoon sheep!

What is the Heisenberg Uncertainty Principle? - Chad Orzel

Check it out! The Uncertainty Principle was introduced by Werner Heisenberg in 1927, as part of a long-running project to develop a complete theory of quantum physics. Heisenberg had developed a quantum theory in 1926 built around the idea that only directly measurable quantities should be considered.
