DIY Air Purifiers for Teachers: Explore Free Designs & Instructions Online

If you’re a teacher returning to the classroom, you may want some extra COVID protection. Thankfully, some researchers and practitioners have created “a design for an in-room air purifier which can remove a significant amount of COVID-19 virus from the air.”

“The design involves making a ‘box’ out of four 20″ MERV-13 filters (the ‘sides’ of the box), a 20″ box fan (the ‘top’ of the box), and a cardboard (the ‘bottom’ of the box’). Air flows in through the filter sides, removing particulates of the sizes that can transport COVID-19 particles, and then flows out through the fan at the top.” These devices can be built from parts available at Home Depot, Walmart and other big box stores, and assembled in about 30-60 minutes. Total cost runs $70-$200. Find designs and a step-by-step instructions here. And read more about the purifier at NPR.

Board Game Ideology — Pretty Much Pop: A Culture Podcast #108

https://podtrac.com/pts/redirect.mp3/traffic.libsyn.com/secure/partiallyexaminedlife/PMP_108_10-7-21.mp3 As board games are becoming increasingly popular with adults, we ask: What’s the relationship between a board game’s mechanics and its narrative? Does the “message” of a board game matter? Your host Mark Linsenmayer is joined by game designer Tommy Maranges , educator Michelle Parrinello-Cason , and ex-philosopher Al Baker to talk about re-skinning games, designing player experiences, play styles, game complexity, and more. Some of the games we mention include Puerto Rico, Monopoly, Settlers of Catan, Sorry, Munchkin, Sushi Go, Welcome To…, Codenames, Pandemic, Occam Horror, Terra Mystica, chess, Ticket to Ride, Splendor, Photosynthesis, Spirit Island, Escape from the Dark Castle, and Wingspan. Some articles that fed our discussion included: “ The Board Games That Ask You to Reenact Colonialism ” by Luke Winkie “ Board Games Are Getting Really, Really Popular ” by Darron Cu...

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...

How Led Zeppelin Stole Their Way to Fame and Fortune

When Bob Dylan released his 2001 album Love and Theft , he lifted the title from a book of the same name by Eric Lott , who studied 19th century American popular music’s musical thefts and contemptuous impersonations. The ambivalence in the title was there, too: musicians of all colors routinely and lovingly stole from each other while developing the jazz and blues traditions that grew into rock and roll. When British invasion bands introduced their version of the blues, it only seemed natural that they would continue the tradition, picking up riffs, licks, and lyrics where they found them, and getting a little slippery about the origins of songs. This was, after all, the music’s history. In truth, most UK blues rockers who picked up other people’s songs changed them completely or credited their authors when it came time to make records. This may not have been tradition but it was ethical business practice. Fans of Led Zeppelin, on the other hand, now listen to their...
