The German word "Volk" usually translates as "people," but it means a whole lot more than that. In 1989 as Germans tore down the Berlin Wall, they chanted, "Wir sind das Volk!" ("We are the people!") Today, though, "Volk" no longer unites Germans. Some understand it to mean everyone living in Germany. Others define it along ethnic lines, thereby excluding immigrants. Now with parliamentary elections looming as they did in 2017 when Patrick Cox first reported this, voters are again wondering: Who are the "Volk" of Germany? Who belongs, and who doesn't?

In 2012, a children’s book in Sweden sparked a nationwide debate— not about the book’s content but a three-letter word used by the main character. Hen was a relatively new, gender-neutral pronoun which challenged Swedish grammar norms. The use of hen tapped into a conversation the country was already having about gender and equality. Can the introduction of one word make a difference in changing societal views? Nina Porzucki goes to Sweden to find out.

If you're under the impression that encyclopedias and dictionaries in the West were always organized from A to Z, think again. We have chosen to classify knowledge in many ways, each reflecting the values of the age. Patrick Cox speaks with Judith Flanders, author of A Place for Everything: The Curious History of Alphabetical Order about the centuries-long resistance to alphabetization, and why A to Z may now be here to stay.

Japan is an ethnically homogenous nation where everyone speaks Japanese, right? Not exactly. Other groups including the Ainu also have called Japan home, perhaps for longer than the Japanese themselves. Today, the Ainu language is spoken by only a handful of people. One of them, Russian-born linguist Anna Bugaeva, takes Patrick Cox to meet Ainu speakers (and non-speakers) on the island of Hokkaido. Along the way, we learn about the mysteries of Ainu, a "language isolate" unrelated to any other language in the world. Bugaeva says Japanese children aren't taught about the Ainu because their presence—and language—contradict standard Japanese history.

Will technology make Braille obsolete as the primary reading tool for blind people? Will talking apps and audiobooks win out over embossed dots? Braille has been written off before; each time it has come back stronger. We trace Braille from its beginnings in Napoleon's France, through the "War of the Dots" in the early 20th century to the age of the smart phone, and beyond.
