With centuries of history to consider, it can be easy to get in a bit of a twist when it comes to the various eras of Western classical music. Here’s a quick guide to the four key periods we usually learn about in music theory: Baroque, Classical, Romantic, 20th Century and beyond.

The Russian invasion of Ukraine could start the painful process of decolonizing Russia. Much depends on whether Russian intellectuals let go of the ideals of a great Russian people and the friendship of “brotherly” nations. This requires accepting the sovereignty and equality of other countries and cultures and admitting responsibility for the Soviet genocidal colonial past. Decolonizing Russian political discourse and culture will debunk the myth of Russian imperial innocence and victimhood and restore the dignity of the colonized.

Ukraina delar historiska rötter med Ryssland. Men landet har aldrig varit så mycket ukrainskt och så lite ryskt som 2022.

The problem with this alluring image is not just that it is false. The myth of Nazi occultism is more than an amusing curiosity, a testament to the power of cinematic suggestion. It actively detracts from a historical understanding of the very themes it highlights. It yields a distorted view of Nazism and a distorted view of occultism. But it also offers an occasion for critical reflection, a chance to see how we might make better sense of the tangled history of occultism in the Nazi era. It might even help us to understand Nazi evil and the not-so-hidden forces behind it.

With several thousand characters to contend with, how were the Japanese able to use typewriters before the advent of digital technology? The answer is the kanji typewriter (和文タイプライター or 邦文タイプライター), which was invented by Kyota Sugimoto in 1915. This invention was deemed so important that it was selected as one of the ten greatest Japanese inventions by the Japanese Patent Office during their 100th anniversary celebrations in 1985. Here are some photos of that first model. (Photos courtesy Canon Semiconductor Equipment.)

For all its transcendental appeals, art has always been inextricably grounded in the material realities of its production, an entwinement most evident in the intriguing history of artists' colours. Focusing in on painting's primary trio of red, yellow, and blue, Philip Ball explores the science and stories behind the pigments, from the red ochre of Lascaux to Yves Klein's blue.

The watermelon originally came from Africa, but after domestication it thrived in hot climates in the Middle East and southern Europe. It probably became common in European gardens and markets around 1600. Old watermelons, like the one in Stanchi's picture, likely tasted pretty good — Nienhuis thinks the sugar content would have been reasonably high, since the melons were eaten fresh and occasionally fermented into wine. But they still looked a lot different.

That's because over time, we've bred watermelons to have the bright red color we recognize today. That fleshy interior is actually the watermelon's placenta, which holds the seeds. Before it was fully domesticated, that placenta lacked the high amounts of lycopene that give it the red color. Through hundreds of years of domestication, we've modified smaller watermelons with a white interior into the larger, lycopene-loaded versions we know today.

Of course, we haven't only changed the color of watermelon. Lately, we've also been experimenting with getting rid of the seeds — which Nienhuis reluctantly calls "the logical progression in domestication." Future generations will at least have photographs to understand what watermelons with seeds looked like. But to see the small, white watermelons of the past, they too will have to look at Renaissance art.

Humans have gotten a lot done in 300,000 years: We invented agriculture, developed writing systems, built cities, created the internet, and shrugged off gravity to land on the moon. These innovations make our past seem long—and stuffed with significance. But in the brief history of life, everything we’ve ever accomplished fits into a tiny sliver of time—just 0.008 percent of the entire continuum shown below. This is how the rise of the animal kingdom stretches out compared with our relatively insignificant existence.

When Europe lost Latin as a shared communication tool, it was a new Babel Tower: Europeans couldn't understand each other any longer except within the boundaries of their national states. Not surprisingly, people who don't understand each other tend to resort to war to sort out conflicts. But Europeans also tried to replace Latin with some non-verbal tools: one was music. It is a long story that needs to be told from the beginning.
