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.

Revisit Scenes of Daily Life in Amsterdam in 1922, with Historic Footage Enhanced by Artificial Intelligence
Welkom in Amsterdam… 1922.
For the last six months, he’s been applying himself to re-rendering documentary footage of city life—Belle Epoque Paris, Tokyo at the start of the the Taish? era, and New York City in 1911—the year of the Triangle Shirtwaist Fire.
It’s possible you’ve seen the footage before, but never so alive in feel. Shiryaev’s renderings trick modern eyes with artificial intelligence, boosting the original frames-per-second rate and resolution, stabilizing and adding color—not necessarily historically accurate.
The herky-jerky bustling quality of the black-and-white originals is transformed into something fuller and more fluid, making the human subjects seem… well, more human.
This Trip Through the Streets of Amsterdam is truly a blast from the past… the antithesis of the social distancing we must currently practice.
Merry citizens jostle shoulder to shoulder, unmasked, snacking, dancing, arms slung around each other… unabashedly curious about the hand-cranked camera turned on them as they go about their business.
A group of women visiting outside a shop laugh and scatter—clearly they weren’t expecting to be filmed in their aprons.
Young boys looking to steal the show push their way to the front, cutting capers and throwing mock punches.
Sorry, lads, the award for Most Memorable Performance by a Juvenile goes to the small fellow at the 4:10 mark. He’s not hamming it up at all, merely taking a quick puff of his cigarette while running alongside a crowd of men on bikes, determined to keep pace with the camera person.
Numerous YouTube viewers have observed with some wonder that all the people who appear, with the distant exception of a baby or two at the end, would be in the grave by now.
They do seem so alive.
Modern eyes should also take note of the absences: no cars, no plastic, no cell phones…
With regard to that, please be forewarned that not all of the YouTube comments have to do with cheeky little boys and babies who would be pushing 100…

The story of popular music in the late 20th century is never complete without an account of the explosive psychedelic rock, funk, Afrobeat, and other hybrid styles that proliferated on the African continent and across Latin American and the Caribbean in the 1960s and 70s. It’s only lately, however, that large audiences are discovering how much pioneering music came out of Kenya, Ghana, Nigeria, and other postcolonial countries, thanks to UK labels like Strut and Soundway (named by The Guardian as “one of the 10 British Labels defining the sound of 2014” and named “Label of the Year” in 2017).
Germany’s Analogue Africa, a label that reissues classic albums from the era, puts it this way: “the future of music happened decades ago.” Only most Western audiences weren’t paying attention—with notable exceptions, of course: superstar drummer Ginger Baker apprenticed himself to Fela Kuti and became an evangelist for African drumming; Brian Eno and Talking Heads’ David Byrne (who also introduced thousands to “world music”) imported the sound of African rock to New Wave in the 80s, as did post-punk bands like Orange Juice and others in Britain, where music from Africa generally had a bigger impact.
But the fusion of African polyrhythms with rock instruments and song structures had been done, and done incredibly well, already by dozens of bands, including several in the East African country of Zambia, which had been British-controlled Northern Rhodesia until its independence in 1964. In the decade after, bands formed around the country to create a unique form of music known as “Zamrock,” as it came to be called, “forged by a particular set of national circumstances,” writes Calum MacNaughton at Music in Africa.
Zamrock bands were influenced by the funk and soul of James Brown and the heavy rock of Hendrix, Deep Purple, Led Zeppelin, The Who, and Cream—the same music everyone else was listening to. As Rikki Ililonga from the band Musi-O-Tunya says in the Vinyl Me, Please mini-documentary above, says, “the hippie time, the flowers, love and everything, Woodstock. We were a part of that culture too. If the record was in the Top 10 in the UK, it was in the Top 10 here.” But Zambia had its own concerns, and its own powerful musical traditions.
“As much as we wanted to play rock from the Western world, we are Africans,” says Jagari Chanda, vocalist for a band called WITCH (“we intend to cause havoc”), “so the other part is from Africa—Zambia. So it’s Zambian type of rock—Zamrock.” The term was coined by Zambian DJ Manasseh Phiri. The music itself “was the soundtrack of Kenneth Kaunda’s socialist ideology of Zambian Humanism,” MacNaughton notes. “In fact, Zamrock owed much of its existence to the nation’s first president and founding father. A guitar-picker who took great pleasure in song” and who promoted local music “via a quota system” imposed on the newly-formed Zambia Broadcasting Service (ZBS).
Vinyl Me, Please has collaborated with MacNaughton and others from Now-Again Records to release 8 Zamrock albums, “7 of which have never been reissued in their original form.” The video above, “The Story of Zamrock,” reflects their decade-long journey to rediscover the 70s scene and its pioneers. In the video at the top from Bandsplaining, you can learn more about Zamrock, which has been gaining prominence in album reissues for the last several years, and which “deserves to be a part of the musical history of Africa in a much bigger way than it has been up to now,” Henning Goranson Sandberg writes at The Guardian.
