The Map of Quantum Physics: A Colorful Animation Explains the Often Misunderstood Branch of Science

In our time, few branches of science have taken as much public abuse as quantum physics, the study of how things behave at the atomic scale. It's not so much that people dislike the subject as they see fit to draft it in support of any given notion: quantum physics, one hears, proves that we have free will, or that Buddhist wisdom is true, or that there is an afterlife, or that nothing really exists. Those claims may or may not be true, but they do not help us at all to understand what quantum physics actually is. For that we'll want to turn to Dominic Wallman, a Youtuber whose channel Domain of Science features clear visual explanations of scientific fields including physics, chemistry, mathematics, as well as the whole domain of science itself — and who also, as luck would have it, is a quantum physics PhD.

With his knowledge of the field, and his modesty as far as what can be definitively said about it, Wallman has designed a map of quantum physics, available for purchase at his web site. In the video above he takes us on a guided tour through the realms into which he has divided up and arranged his subject, beginning with the "pre-quantum mysteries," inquiries into which led to its foundation.

From there he continues on to the foundations of quantum physics, a territory that includes such potentially familiar landmarks as particle-wave duality, Heisenberg's uncertainty principle, and the Schrödinger equation — though not yet his cat, another favorite quantum-physics reference among those who don't know much about quantum physics.

Alas, as Wallman explains in the subsequent "quantum phenomena" section, Schrödinger's cat is "not very helpful, because it was originally designed to show how absurd quantum mechanics seems, as cats can't be alive and dead at the same time." But then, this is a field that proceeds from absurdity, or at least from the fact that its observations at first made no sense by the traditional laws of physics. There follow forays into quantum technology (lasers, solar panels, MRI machines), quantum information (computing, cryptography, the prospect teleportation), and a variety of subfields including condensed matter physics, quantum biology, and quantum chemistry. Though detailed enough to require more than one viewing, Wallman's map also makes clear how much of quantum physics remains unexplored — and most encouragingly of all, leaves off its supposed philosophical, or existential implications.

Ishkur’s Guide to Electronic Music: An Interactive, Encyclopedic Data Visualization of 120 Years of Electronic Music

In a very short span of time, the descriptor “electronic music” has come to sound as overly broad as “classical.” But where what we (often incorrectly) call classical developed over hundreds of years, electronic music proliferated into hundreds of fractal forms in only decades. A far steeper quality curve may have to do with the ease of its creation, but it’s also a factor of this accelerated evolution. Music made by machines has transformed since its early 20th-century beginnings from obscure avant-garde experiments to massively popular genres of global dance and pop. This proliferation, notes Ishkur—designer of Ishkur’s Guide to Electronic Music —hasn't always been to the good. Take what he calls “trendwhoring,” a phenomenon that spawns dozens of new works and subgenera in short order, though it’s arguable whether many of them should exist. Ishkur, describes this process below in an excerpt from his erudite, sardonic “Frequently Unasked Questions”: If fart noises were sudde...

A 10 Billion Pixel Scan of Vermeer’s Masterpiece Girl with a Pearl Earring: Explore It Online

We admire Johannes Vermeer’s  Girl with a Pearl Earring   for many reasons , not least that it looks exactly like a girl with a pearl earring. Or at least it does from a distance, as the master of light himself no doubt stepped back to confirm countless times during the painting process, at any moment of which he would have been more concerned with the brushstrokes constituting only a small part of the image. But even Vermeer himself could have perceived only so much detail of the painting that would become his masterpiece. https://www.youtube.com/watch?v=cKaZYTwmjwU Now, more than 350 years after its completion, we can get a closer view of Girl with a Pearl Earring  than anyone has before through a newly released  10 billion-pixel panorama . At this resolution, writes Petapixel’s Jason Schneider , we can “see the painting down to the level of 4.4-microns per pixel.” Undertaken by Emilien Leonhardt and Vincent Sabatier of 3D microscope maker Hirox Europe ...

Howard Zinn’s Recommended Reading List for Activists Who Want to Change the World

Image by via Wikimedia Commons Back in college, I spotted A People’s History of the United States   in the bags and on the bookshelves of many a fellow undergraduate. By that time, Howard Zinn’s alternative telling of the American story had been popular reading material for a couple of decades, just as it presumably remains a couple more decades on. Even now, a dozen years after Zinn’s death, his ideas about how to approach U.S. history through non-standard points of view remain widely influential. Just last month, Radical Reads featured the reading list he originally drew up for the  Socialist Worker , pitched at “activists interested in making their own history.” Zinn’s recommendations naturally include the work of other historians, from Gary Nash’s Red, White and Black: The Peoples of Early America (“a pioneering work of ‘multiculturalism’ dealing with racial interactions in the colonial period”) to Vincent Harding’s There Is a River: The Black Struggle for ...
