DIY Air Purifiers for Teachers: Free Designs & Step-by-Step 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.

What It’s Like to Actually Fight in Medieval Armor

Ever won­der what it was like to real­ly fight while wear­ing a full suit of armor? We’ve fea­tured a few his­tor­i­cal recon­struc­tions here on Open Cul­ture, includ­ing a demon­stra­tion of the var­i­ous ways com­bat­ants would van­quish their foe—includ­ing a sword right between the eyes. We’ve also shown you how long it took to cre­ate a suit of armor and the clever flex­i­bil­i­ty built into them. But real­ly, don’t we want to see what it would be like in a full melee? In the above Vice doc­u­men­tary, you can final­ly sate your blood­lust.

Not that any­one dies in the MMA-like sword-and-chain­mail brawls. In these pub­lic com­pe­ti­tions, the weapons are blunt­ed and con­tes­tants fight “not to the death, just until they fall over,” as the nar­ra­tor some­what sad­ly explains. It is just a legit sport as any oth­er fight­ing chal­lenge, and the injuries are real. There’s no fool­ing around with these peo­ple. They are seri­ous, and a nation’s hon­or is still at stake.

This mini-doc fol­lows the Amer­i­can team to the Inter­na­tion­al Medieval Com­bat Fed­er­a­tion World Cham­pi­onships in Mon­te­mor-o-Vel­ho in Por­tu­gal. What looks like a reg­u­lar Renais­sance faire is only the dec­o­ra­tions around the main, incred­i­bly vio­lent event. We see bat­tles with longswords, short axes, shields used offen­sive­ly and defen­sive­ly, and a lot of push­ing and shov­ing. Con­tes­tants go head-to-head, or five against five, or twelve against twelve.

Twen­ty-six coun­tries take part, and I have to say for all the jin­go­is­tic hoo-hah I try to ignore, the Amer­i­can team’s very nice­ly designed stars and stripes bat­tle gear looked pret­ty damn cool. The Vice team also dis­cov­er an inter­est­ing cast of char­ac­ters, like the Tex­an who wears his cow­boy hat when he’s not wear­ing his com­bat hel­met; the man who describes his fight­ing style as “nerd rage”; and the cou­ple on their hon­ey­moon who met while bru­tal­ly beat­ing each oth­er in an ear­li­er com­pe­ti­tion. (No, the knights here are not all men.).

There are injuries, sprains, bro­ken bones. There’s also the mad­ness of inhal­ing too much of your own CO2 inside the hel­met; and smelling the ozone when a spark of met­al-upon-met­al flies into the hel­met.

Thank­ful­ly nobody is fight­ing to the death or for King/Queen and Coun­try. Just for the fun of adren­a­lin-based com­pe­ti­tion and brag­ging rights.

How Italian Physicist Laura Bassi Became the First Woman to Have an Academic Career in the 18th Century

The prac­tice and priv­i­lege of aca­d­e­m­ic sci­ence has been slow in trick­ling down from its ori­gins as a pur­suit of leisured gen­tle­man. While many a leisured lady may have tak­en an inter­est in sci­ence, math, or phi­los­o­phy, most women were denied par­tic­i­pa­tion in aca­d­e­m­ic insti­tu­tions and schol­ar­ly soci­eties dur­ing the sci­en­tif­ic rev­o­lu­tion of the 1700s. Only a hand­ful of women — sev­en known in total — were grant­ed doc­tor­al degrees before the year 1800. It wasn’t until 1678 that a female schol­ar was giv­en the dis­tinc­tion, some four cen­turies or so after the doc­tor­ate came into being. While sev­er­al intel­lec­tu­als and even cler­ics of the time held pro­gres­sive atti­tudes about gen­der and edu­ca­tion, they were a decid­ed minor­i­ty.

Curi­ous­ly, four of the first sev­en women to earn doc­tor­al degrees were from Italy, begin­ning with Ele­na Cornaro Pis­copia at the Uni­ver­si­ty of Pad­ua. Next came Lau­ra Bassi, who earned her degree from the Uni­ver­si­ty of Bologna in 1732. There she dis­tin­guished her­self in physics, math­e­mat­ics, and nat­ur­al phi­los­o­phy and became the first salaried woman to teach at a uni­ver­si­ty (she was at one time the university’s high­est paid employ­ee). Bassi was the chief pop­u­lar­iz­er of New­ton­ian physics in Italy in the 18th cen­tu­ry and enjoyed sig­nif­i­cant sup­port from the Arch­bish­op of Bologna, Pros­pero Lam­ber­ti­ni, who — when he became Pope Bene­dict XIV — elect­ed her as the 24th mem­ber of an elite sci­en­tif­ic soci­ety called the Benedet­ti­ni.

“Bassi was wide­ly admired as an excel­lent exper­i­menter and one of the best teach­ers of New­ton­ian physics of her gen­er­a­tion,” says Paula Find­len, Stan­ford pro­fes­sor of his­to­ry. “She inspired some of the most impor­tant male sci­en­tists of the next gen­er­a­tion while also serv­ing as a pub­lic exam­ple of a woman shap­ing the nature of knowl­edge in an era in which few women could imag­ine play­ing such a role.” She also played the role avail­able to most women of the time as a moth­er of eight and wife of Giuseppe Ver­at­ti, also a sci­en­tist.

Bassi was not allowed to teach class­es of men at the uni­ver­si­ty — only spe­cial lec­tures open to the pub­lic. But in 1740, she was grant­ed per­mis­sion to lec­ture at her home, and her fame spread, as Find­len writes at Physics World:

 Bassi was wide­ly known through­out Europe, and as far away as Amer­i­ca, as the woman who under­stood New­ton. The insti­tu­tion­al recog­ni­tion that she received, how­ev­er, made her the emblem­at­ic female sci­en­tist of her gen­er­a­tion. A uni­ver­si­ty grad­u­ate, salaried pro­fes­sor and aca­d­e­mi­cian (a mem­ber of a pres­ti­gious acad­e­my), Bassi may well have been the first woman to have embarked upon a full-fledged sci­en­tif­ic career.

Poems were writ­ten about Bassi’s suc­cess­es in demon­strat­ing New­ton­ian optics; “news of her accom­plish­ments trav­eled far and wide,” reach­ing the ear of Ben­jamin Franklin, whose work with elec­tric­i­ty Bassi fol­lowed keen­ly. In Bologna, sur­prise at Bassi’s achieve­ments was tem­pered by a cul­ture known for “cel­e­brat­ing female suc­cess.” Indeed, the city was “jok­ing­ly known as a ‘par­adise for women,’” writes Find­len. Bassi’s father was deter­mined that she have an edu­ca­tion equal to any of her class, and her fam­i­ly inher­it­ed mon­ey that had been equal­ly divid­ed between daugh­ters and sons for gen­er­a­tions; her sons “found them­selves heirs to the prop­er­ty that came to the fam­i­ly through Laura’s mater­nal line,” notes the Stan­ford Uni­ver­si­ty col­lec­tion of Bassi’s per­son­al papers.

Bassi’s aca­d­e­m­ic work is held at the Acad­e­my of Sci­ences in Bologna. Of the papers that sur­vive, “thir­teen are on physics, eleven are on hydraulics, two are on math­e­mat­ics, one is on mechan­ics, one is on tech­nol­o­gy, and one is on chem­istry,” writes a Uni­ver­si­ty of St. Andrew’s biog­ra­phy. In 1776, a year usu­al­ly remem­bered for the for­ma­tion of a gov­ern­ment of leisured men across the Atlantic, Bassi was appoint­ed to the Chair of Exper­i­men­tal Physics at Bologna, an appoint­ment that not only meant her hus­band became her assis­tant, but also that she became the “first woman appoint­ed to a chair of physics at any uni­ver­si­ty in the world.”

Bologna was proud of its dis­tin­guished daugh­ter, but per­haps still thought of her as an odd­i­ty and a token. As Dr. Eleono­ra Ada­mi notes in a charm­ing biog­ra­phy at sci-fi illus­trat­ed sto­ries, the city once struck a medal in her hon­or, “com­mem­o­rat­ing her first lec­ture series with the phrase ‘Soli cui fas vidisse Min­er­vam,’” which trans­lates rough­ly to “the only one allowed to see Min­er­va.” But her exam­ple inspired oth­er women, like Cristi­na Roc­cati, who earned a doc­tor­ate from Bologna in 1750, and Dorothea Erxleben, who became the first woman to earn a Doc­tor­ate in Med­i­cine four years lat­er at the Uni­ver­si­ty of Halle. Such sin­gu­lar suc­cess­es did not change the patri­ar­chal cul­ture of acad­e­mia, but they start­ed the trick­le that would in time become sev­er­al branch­ing streams of women suc­ceed­ing in the sci­ences.

Alice in Wonderland Syndrome: The Real Perceptual Disorder That May Have Shaped Lewis Carroll’s Creative World

Alice’s Adven­tures in Won­der­land isn’t just a beloved chil­dren’s sto­ry: it’s also a neu­ropsy­cho­log­i­cal  syn­drome. Or rather the words “Alice in Won­der­land,” as Lewis Car­rol­l’s book is com­mon­ly known, have also become attached to a con­di­tion that, though not harm­ful in itself, caus­es dis­tor­tions in the suf­fer­er’s per­cep­tion of real­i­ty. Oth­er names include dys­metrop­sia or Tod­d’s syn­drome, the lat­ter of which pays trib­ute to the con­sul­tant psy­chi­a­trist John Todd, who defined the dis­or­der in 1955. He described his patients as see­ing some objects as much larg­er than they real­ly were and oth­er objects as much small­er, result­ing in chal­lenges not entire­ly unlike those faced by Alice when put by Car­roll through her grow­ing-and-shrink­ing paces.

Todd also sug­gest­ed that Car­roll had writ­ten from expe­ri­ence, draw­ing inspi­ra­tion from the hal­lu­ci­na­tions he expe­ri­enced when afflict­ed with what he called “bil­ious headache.”  The trans­for­ma­tions Alice feels her­self under­go­ing after she drinks from the “DRINK ME” bot­tle and eats the “EAT ME” cake are now known, in the neu­ropsy­cho­log­i­cal lit­er­a­ture, as macrop­sia and microp­sia.

“I was in the kitchen talk­ing to my wife,” writes nov­el­ist Craig Rus­sell of one of his own bouts of the lat­ter. “I was huge­ly ani­mat­ed and full of ener­gy, hav­ing just put three days’ worth of writ­ing on the page in one morn­ing and was burst­ing with ideas for new books. Then, quite calm­ly, I explained to my wife that half her face had dis­ap­peared. As I looked around me, bits of the world were miss­ing too.”

Though “many have spec­u­lat­ed that Lewis Car­roll took some kind of mind-alter­ing drug and based the Alice books on his hal­lu­ci­na­to­ry expe­ri­ences,” writes Rus­sell, “the truth is that he too suf­fered from the con­di­tion, but in a more severe and pro­tract­ed way,” com­bined with ocu­lar migraine. Rus­sell also notes that the sci-fi vision­ary Philip K. Dick, though “nev­er diag­nosed as suf­fer­ing from migrain­ous aura or tem­po­ral lobe epilep­sy,” left behind a body of work that has has giv­en rise to “a grow­ing belief that the expe­ri­ences he described were attrib­ut­able to the lat­ter, par­tic­u­lar­ly.” Suit­ably, clas­sic Alice in Won­der­land syn­drome “tends to be much more com­mon in child­hood” and dis­ap­pear in matu­ri­ty. One suf­fer­er doc­u­ment­ed in the sci­en­tif­ic lit­er­a­ture is just six years old, younger even than Car­rol­l’s eter­nal lit­tle girl — pre­sum­ably, an eter­nal seer of real­i­ty in her own way.

The Strange Magic of Jimi Hendrix’s “Voodoo Chile”

Poor Poly­phon­ic. He was just about to deliv­er anoth­er per­fect­ly mixed trea­tise on a clas­sic rock mag­num opus when the YouTube algo­rithm and the Jimi Hen­drix Estate stepped in to stop him before pub­lish­ing. So while you can watch this real-time expli­ca­tion of Hendrix’s more-than-just-a-jam “Voodoo Chile” with just the the graph­ics and the nar­ra­tion, you should cue up the 15 minute track how­ev­er you can (for exam­ple on Spo­ti­fy), and then press play when when the video gives the sig­nal. (This might be the first YouTube explain­er video to ask for copy­right-skirt­ing help.)

And any­way, you should have a copy of Elec­tric Lady­land, right? It’s the one where Hen­drix and the Expe­ri­ence real­ly push all the bound­aries, tak­ing rock, blues, jazz, psy­che­delia, sci-fi, everything…all out as far as pos­si­ble in the stu­dio. It’s the one that intro­duced future mem­bers of the Band of Gyp­sies. And it’s the one that hints of every­thing that might have been, if Hen­drix hadn’t passed away soon after.

Now, clas­sic rock radio usu­al­ly plays the much short­er and less laid back “Voodoo Child (Slight Return)” that clos­es the album. But this essay is about the longest track on Elec­tric Lady­land, the one that ends side one. This is the track that Hen­drix want­ed to sound like a light night jam at New York club The Scene—and which he record­ed after one par­tic­u­lar night doing just that. He taped the audi­ence effects soon after. Steve Win­wood is on key­boards. Jack Casady from Jef­fer­son Air­plane plays bass. And Mitch Mitchell turns in one of his great­est per­for­mances and solos.

In the lyrics, Poly­phon­ic notes, Hen­drix con­nects the blues to his Chero­kee her­itage and to voodoo, to sex, and then beyond into sci­ence fic­tion land­scapes. The song is a self-por­trait, show­ing the past, the influ­ence, the train­ing, and then the poten­tial that music, mag­ic, and (let’s face it) LSD could bring. The band is vib­ing. Win­wood drops riffs that are more British folk than Chica­go blues. Hen­drix strays far beyond the orbit of blues, swings past it one more time on his own slight return, and then explodes into star­dust.

Polyphonic’s video also looks beau­ti­ful and per­fect­ly inter­spers­es his cri­tique with the song’s main sec­tions. It may have sound­ed like a jam, but Hen­drix care­ful­ly designed it to flow the way it does. And Poly­phon­ic fol­lows suit. It is a high­ly enjoy­able walk through a track (again find it on Spo­ti­fy here) many already know, reawak­en­ing a sense of won­der about all its inher­ent, strange genius.

Elvis Presley Gets the Polio Vaccine on The Ed Sullivan Show, Persuading Millions to Get Vaccinated (1956)

No one liv­ing has expe­ri­enced a viral event the size and scope of COVID-19. Maybe the unprece­dent­ed nature of the pan­dem­ic explains some of the vac­cine resis­tance. Dis­eases of such vir­u­lence became rare in places with ready access to vac­cines, and thus, iron­i­cal­ly, over time, have come to seem less dan­ger­ous. But there are still many peo­ple in wealthy nations who remem­ber polio, an epi­dem­ic that dragged on through the first half of the 20th cen­tu­ry before Jonas Salk per­fect­ed his vac­cine in the mid-fifties.

Polio’s dev­as­ta­tion has been summed up visu­al­ly in text­books and doc­u­men­taries by the ter­ri­fy­ing iron lung, an ear­ly ven­ti­la­tor. “At the height of the out­breaks in the late 1940s,” Meilan Sol­ly writes at Smith­son­ian, “polio par­a­lyzed an aver­age of more than 35,000 peo­ple each year,” par­tic­u­lar­ly affect­ing chil­dren, with 3,000 deaths in 1952 alone. “Spread viral­ly, it proved fatal for two out of ten vic­tims afflict­ed with paral­y­sis. Though mil­lions of par­ents rushed to inoc­u­late their chil­dren fol­low­ing the intro­duc­tion of Jonas Salk’s vac­cine in 1955, teenagers and young adults had proven more reluc­tant to get the shot.”

At the time, there were no vio­lent, orga­nized protests against the vac­cine, nor was resis­tance framed as a patri­ot­ic act of polit­i­cal loy­al­ty. But “cost, apa­thy and igno­rance became seri­ous set­backs to the erad­i­ca­tion effort,” says his­to­ri­an Stephen Mawd­s­ley. And, then as now, irre­spon­si­ble media per­son­al­i­ties with large plat­forms and lit­tle knowl­edge could do a lot of harm to the public’s con­fi­dence in life-sav­ing pub­lic health mea­sures, as when influ­en­tial gos­sip colum­nist Wal­ter Winchell wrote that the vac­cine “may be a killer,” dis­cour­ag­ing count­less read­ers from get­ting a shot.

When Elvis Pres­ley made his first appear­ance on Ed Sul­li­van’s show in 1956, “immu­niza­tion lev­els among Amer­i­can teens were at an abysmal 0.6 per­cent,” note Hal Her­sh­field and Ilana Brody at Sci­en­tif­ic Amer­i­can. To counter impres­sions that the polio vac­cine was dan­ger­ous, pub­lic health offi­cials did not sole­ly rely on get­ting more and bet­ter infor­ma­tion to the pub­lic; they also took seri­ous­ly what Her­sh­field and Brody call the “cru­cial ingre­di­ents inher­ent to many of the most effec­tive behav­ioral change cam­paigns: social influ­ence, social norms and vivid exam­ples.” Sat­is­fy­ing all three, Elvis stepped up and agreed to get vac­ci­nat­ed “in front of mil­lions” back­stage before his sec­ond appear­ance on the Sul­li­van show.

Elvis could not have been more famous, and the cam­paign was a suc­cess for its tar­get audi­ence, estab­lish­ing a new social norm through influ­ence and exam­ple: “Vac­ci­na­tion rates among Amer­i­can youth sky­rock­et­ed to 80 per­cent after just six months.” Despite the threat he sup­pos­ed­ly posed to the estab­lish­ment, Elvis him­self was ready to serve the pub­lic. “I cer­tain­ly nev­er wan­na do any­thing,” he said, “that would be a wrong influ­ence.” See in the short video at the top how Amer­i­can pub­lic health offi­cials stopped mil­lions of pre­ventable deaths and dis­abil­i­ties by admit­ting a fact pro­pa­gan­dists and adver­tis­ers nev­er shy from — humans, on the whole, are eas­i­ly per­suad­ed by celebri­ties. Some­times they can even be per­suad­ed for the good.

How Victorian Homes Turned Deadly: Exploding Stoves, Poison Wallpaper, Ever-Tighter Corsets & More

The British have a num­ber of say­ings that strike lis­ten­ers of oth­er Eng­lish-speak­ing nation­al­i­ties as odd. “Safe as hous­es” has always had a curi­ous ring to my Amer­i­can ear, but it turns out to be quite iron­ic as well: the expres­sion grew pop­u­lar in the Vic­to­ri­an era, a time when Lon­don­ers were as like­ly to be killed by their own hous­es as any­thing else. That, at least, is the impres­sion giv­en by “The Bizarre Ways Vic­to­ri­ans Sab­o­taged Their Own Health & Lives,” the doc­u­men­tary inves­ti­ga­tion star­ring his­to­ri­an Suzan­nah Lip­scomb above.

Through­out the sec­ond half of the 19th cen­tu­ry, many an Eng­lish­man would have regard­ed him­self as liv­ing at the apex of civ­i­liza­tion. He would­n’t have been wrong, exact­ly, since that place and time wit­nessed an unprece­dent­ed num­ber of large-scale inno­va­tions indus­tri­al, sci­en­tif­ic, and domes­tic.

But a lit­tle knowl­edge can be a dan­ger­ous thing, and the Vic­to­ri­ans’ under­stand­ing of their favorite new tech­nolo­gies’ ben­e­fits ran con­sid­er­ably ahead of their under­stand­ing of the atten­dant threats. The haz­ards of the dark satan­ic mills were com­par­a­tive­ly obvi­ous, but even the heights of domes­tic bliss, as that era con­ceived of it, could turn dead­ly.

Speak­ing with a vari­ety of experts, Lip­scomb inves­ti­gates the dark side of a vari­ety of accou­trements of the Vic­to­ri­an high (or at least com­fort­ably mid­dle-class) life. These harmed not just men but women and chil­dren as well: take the breed­ing-ground of dis­ease that was the infant feed­ing bot­tle, or the organ-com­press­ing corset — one of which, adher­ing to the expe­ri­en­tial sen­si­bil­i­ty of British tele­vi­sion, Lip­scomb tries on and strug­gles with her­self. Mem­bers of the even­tu­al anti-corset revolt includ­ed Con­stance Lloyd, wife of Oscar Wilde, and it is Wilde’s apoc­ryphal final words that come to mind when the video gets into the arsenic con­tent of Vic­to­ri­an wall­pa­per. “Either that wall­pa­per goes, or I do,” Wilde is imag­ined to have said — and as mod­ern sci­ence now proves, it could have been more than a mat­ter of taste.

The Roman Colosseum Has a Twin in Tunisia: Discover the Amphitheater of El Jem, One of the Best-Preserved Roman Ruins in the World

Image via Wiki­me­dia Com­mons

When Rome con­quered Carthage in the Third Punic War (149–146 BC), the Repub­lic renamed the region Africa, for Afri, a word the Berbers used for local peo­ple in present-day Tunisia. (The Ara­bic word for the region was Ifriqiya.) There­after would the Roman Empire have a strong­hold in North Africa: Carthage, the cap­i­tal of the African Province under Julius and Augus­tus Cae­sar and their suc­ces­sors. The province thrived. Sec­ond only to the city of Carthage in the region, the city of Thys­drus was an impor­tant cen­ter of olive oil pro­duc­tion and the home­town of Roman Emper­or Sep­ti­m­ius Severus, who bestowed impe­r­i­al favor upon it, grant­i­ng par­tial Roman cit­i­zen­ship to its inhab­i­tants.

In 238 AD, con­struc­tion began on an amphithe­ater in Thys­drus that would rival its largest cousins in Rome, the famed Amphithe­ater of El Jem. “Designed to seat a whop­ping crowd of 35,000 peo­ple,” writes Atlas Obscu­ra, El Jem was list­ed as a UNESCO World Her­itage site in 1979. Built entire­ly of stone blocks, the mas­sive the­ater was “mod­eled on the Col­i­se­um of Rome,” notes UNESCO, “with­out being an exact copy of the Fla­vian con­struc­tion…. Its facade com­pris­es three lev­els of arcades of Corinthi­an or com­pos­ite style. Inside, the mon­u­ment has con­served most of the sup­port­ing infra­struc­ture for the tiered seat­ing. The wall of the podi­um, the are­na and the under­ground pas­sages are prac­ti­cal­ly intact.”

Although the small city of El Jem hard­ly fea­tures on tours of the clas­si­cal past, it was, in the time of the Amphitheater’s con­struc­tion, a promi­nent site of strug­gle for con­trol over the Empire. The year 238 “was par­tic­u­lar­ly tumul­tuous,” Atlas Obscu­ra explains, due to a “revolt by the pop­u­la­tion of Thys­drus (El Jem), who opposed the enor­mous tax­a­tion amounts being levied by the Emper­or Maximinus’s local procu­ra­tor.” A riot of 50,000 peo­ple led to the ascen­sion of Gor­dian I, who ruled for 21 days dur­ing the “Year of the Six Emper­ors,” when “in just one year, six dif­fer­ent peo­ple were pro­claimed Emper­ors of Rome.”

From such fraught begin­nings, the mas­sive stone struc­ture of the El Jem Amphithe­ater went on to serve as a fortress dur­ing inva­sions of Van­dals and Arabs in the 5th-7th cen­turies. A thou­sand years after the Islam­ic con­quest, El Jem became a fortress dur­ing the Rev­o­lu­tions of Tunis. Lat­er cen­turies saw the amphithe­ater used for salt­pe­tre man­u­fac­ture, grain stor­age, and mar­ket stalls.

Despite hun­dreds of years of human activ­i­ty, in vio­lent upheavals and every­day busi­ness, El Jem remains one of the best pre­served Roman ruins in the world and one of the largest out­door the­aters ever con­struct­ed. More impor­tant­ly, it marks the site of one of North Africa’s first impe­r­i­al occu­pa­tions, one that would des­ig­nate a region — and even­tu­al­ly a con­ti­nent with a dizzy­ing­ly diverse mix of peo­ples — as “African.”

King Arthur in Film: Our Most Enduring Popular Entertainment Franchise? Pretty Much Pop: A Culture Podcast #104

With the recent the­atri­cal release of The Green Knight, your Pret­ty Much Pop host Mark Lin­sen­may­er, return­ing host Bri­an Hirt, plus Den of Geek’s David Crow and the very British Al Bak­er con­sid­er the range of cin­e­mat­ic Arthuri­ana, includ­ing Excal­ibur (1981), Camelot (1967), King Arthur (2004), King Arthur: Leg­end of the Sword (2017), First Knight (1995), Sword of the Valiant (1983), Sir Gawain and the Green Knight (1973), and Mon­ty Python and the Holy Grail (1975).

Arthuri­ana encom­pass­es numer­ous (some­times con­tra­dict­ing) sto­ries that accrued and evolved for near­ly 1000 years after the prob­a­ble exis­tence of the unknown per­son who was the his­tor­i­cal source for the char­ac­ter before the 14th cen­tu­ry poem (author unknown) Sir Gawain and the Green Knight, and then in the 15th cen­tu­ry Sir Thomas Mal­o­ry wrote Le Morte d’Arthur, which pro­vid­ed the tem­plate for well-known mod­ern retellings like T.H. White’s The Once and Future King (1958).

The length and com­plex­i­ty of this mythol­o­gy makes a sin­gle film prob­lem­at­ic, with most set­tling on the love tri­an­gle between Arthur, Lancelot, and Guin­e­vere lead­ing to Camelot’s down­fall. Mul­ti­ple TV treat­ments have tried to do it jus­tice, and if Guy Ritchie’s King Arthur: Leg­end of the Sword had been a box office suc­cess, then we’d cur­rent­ly be see­ing mul­ti­ple films in an Arthuri­an cin­e­mat­ic uni­verse. By pick­ing a small­er sto­ry and not try­ing too hard to tie it to King Arthur (who appears but is not named), The Green Knight is able to be more cre­ative in paint­ing and updat­ing the strange sto­ry of Sir Gawain, who in pre­vi­ous cin­e­mat­ic out­ings (includ­ing Sword of the Valiant where Sean Con­nery played The Green Knight) involved Gawain involved in a series of non­sen­si­cal adven­tures far removed from the events told in the orig­i­nal poem.

We talk through char­ac­ter­i­za­tion in a myth­ic sto­ry, styl­iz­ing the epic (how much vio­lence? how weird?), its sta­tus as pub­lic domain mate­r­i­al (like Robin Hood and Sher­lock Holmes), and the moral les­son of the orig­i­nal Gawain poem and what direc­tor David Low­ery did with that for the new film. Is the new film actu­al­ly enjoy­able, or just care­ful­ly thought through and art­ful­ly shot? Note that we don’t spoil any­thing sig­nif­i­cant about The Green Knight until the last ten min­utes, so it’s fine if you haven’t seen it (Al had­n’t either).

The Very First Webcam Was Invented to Keep an Eye on a Coffee Pot at Cambridge University

The inter­net as we know it today began with a cof­fee pot. Despite the ring of exag­ger­a­tion, that claim isn’t actu­al­ly so far-fetched. When most of us go online, we expect some­thing new: often not just some­thing new to read, but some­thing new to watch. This, as those of us past a cer­tain age will recall, was not the case with the ear­ly World Wide Web, con­sist­ing as it most­ly did of sta­t­ic pages of text, updat­ed irreg­u­lar­ly if at all. Younger read­ers will have to imag­ine even that being a cut­ting-edge thrill, but we did­n’t real­ly feel like we were liv­ing in the future until the fall of 1993, when XCof­fee first went live.

This ground­break­ing tech­no­log­i­cal project “start­ed back in the dark days of 1991,” writes co-cre­ator Quentin Stafford-Fras­er, “when the World Wide Web was lit­tle more than a glint in CERN’s eye.” At the time, Stafford-Fras­er was employed as one of fif­teen researchers in the “Tro­jan Room” of the Uni­ver­si­ty of Cam­bridge Com­put­er Lab. “Being poor, impov­er­ished aca­d­e­mics, we only had one cof­fee fil­ter machine between us, which lived in the cor­ri­dor just out­side the Tro­jan Room. How­ev­er, being high­ly ded­i­cat­ed and hard-work­ing aca­d­e­mics, we got through a lot of cof­fee, and when a fresh pot was brewed, it often did­n’t last long.”

It occurred to Stafford-Fras­er to train an unused video cam­era from the Tro­jan Room on the cof­fee pot (and thus the amount of cof­fee avail­able with­in), then con­nect it to a com­put­er, specif­i­cal­ly an Acorn Archimedes. His col­league Paul Jardet­zky “wrote a ‘serv­er’ pro­gram, which ran on that machine and cap­tured images of the pot every few sec­onds at var­i­ous res­o­lu­tions, and I wrote a ‘client’ pro­gram which every­body could run, which con­nect­ed to the serv­er and dis­played an icon-sized image of the pot in the cor­ner of the screen. The image was only updat­ed about three times a minute, but that was fine because the pot filled rather slow­ly, and it was only greyscale, which was also fine, because so was the cof­fee.”

XCof­fee, the result­ing pro­gram, was meant only to pro­vide this much-need­ed infor­ma­tion to Com­put­er Lab mem­bers else­where in the build­ing. But after the release of image-dis­play­ing web browsers in 1993, it found a much wider audi­ence as the world’s first stream­ing web­cam. Stafford-Fraser’s suc­ces­sors “res­ur­rect­ed the sys­tem, treat­ed it to a new frame grab­ber, and made the images avail­able on the World Wide Web. Since then, hun­dreds of thou­sands of peo­ple have looked at the cof­fee pot, mak­ing it undoubt­ed­ly the most famous in the world.” Stafford-Fras­er wrote these words in 1995; in the years there­after XCof­fee went on to receive mil­lions of views before its even­tu­al shut­down in 2001.

In the Cen­tre for Com­put­ing His­to­ry video above, Stafford-Fras­er shows the very Olivet­ti cam­era he orig­i­nal­ly used to mon­i­tor the cof­fee lev­el. (He’d pre­vi­ous­ly worked at the Olivet­ti Research Lab­o­ra­to­ry, whose par­ent com­pa­ny also owned Acorn Com­put­ers.) “We could see things at a dis­tance before,” he says. “We could view tele­vi­sion pro­grams, we could look through tele­scopes.” But only after the Tro­jan Room’s cof­fee pot hit the inter­net could we “see what’s hap­pen­ing now, some­where else in the world,” on demand. Thir­ty years after XCof­fee’s devel­op­ment, we’re mes­mer­ized by live-stream­ing stars and sur­round­ed by “smart” home appli­ances, hop­ing for noth­ing so much as way to con­cen­trate on our imme­di­ate sur­round­ings again — to wake up, if you like, and smell the cof­fee.

What Makes Basquiat’s Untitled Great Art: One Painting Says Everything Basquiat Wanted to Say About America, Art & Being Black in Both Worlds

They wouldn’t have let Jean-Michel into a Tiffany’s if he want­ed to use the bath­room or if he went to buy an engage­ment ring and pulled a wad of cash out of his pock­et. 

– Stephen Tor­ton, Jean-Michel Basquiat’s stu­dio assis­tant

When Jean-Michel Basquiat’s Unti­tled (Skull) sold for $110.5 mil­lion in 2017 to Japan­ese bil­lion­aire Yusaku Mae­sawa, the artist joined the ranks of Da Vin­ci, De Koon­ing, and Picas­so as one of the top sell­ing painters in the world, sur­pass­ing a pre­vi­ous record set in 2013 by his men­tor Andy Warhol’s work. Unti­tled dates from 1982, dur­ing “the young Basquiat’s mer­cu­r­ial ear­ly years,” writes Ben Davis at Art­net, “even before his first gallery show at Anni­na Nosei, when he was still a Caribbean-Amer­i­can kid from Brook­lyn ener­get­i­cal­ly boot­strap­ping him­self into the lime­light of the down­town art scene.” It is this peri­od that most inter­ests col­lec­tors like Mae­sawa.

Basquiat’s tran­si­tion from graf­fi­ti artist to art world dar­ling was dra­mat­ic, cel­e­bra­to­ry, and self-destruc­tive, all char­ac­ter­is­tics of his work. But crit­i­cal prim­i­tivism reduced him to a token — an art world atti­tude saw Basquiats as objects to be stripped of con­text, turned into dec­o­ra­tive badges of authen­tic­i­ty and world­li­ness. “Maezawa’s head paint­ing pos­sess­es a loud, gnash­ing, and con­fi­dent aura,” Shan­non Lee writes at Art­sy. But the artist’s “use of skulls… is deeply root­ed in his iden­ti­ty as a Black artist in Amer­i­ca. They are strong­ly evoca­tive of African masks, which have been so fetishized by the art mar­ket since mod­ernists like Picas­so appro­pri­at­ed them from their native con­texts.”

But head/skull motifs in Basquiat’s work are not only state­ments of dias­poric Black iden­ti­ty — they emerge through his the­mat­ic play of human embod­i­ment, men­tal illness/health, the com­pe­ti­tions of the graf­fi­ti world and the headgames of the art world, which Basquiat both mas­tered and cri­tiqued as a can­ny out­sider. “No sub­ject is more pow­er­ful or more sought after in the oeu­vre of Jean-Michel Basquiat,” notes Christie’s New York, “than the sin­gu­lar skull.” Though maybe not the most repro­duced of Basquiat’s heads, 1982’s Unti­tled — argues the Great Art Explained video above — exem­pli­fies the themes.

At only 22 years old, Basquiat pro­duced “a sin­gle paint­ing” that said “every­thing he want­ed to say about Amer­i­ca, about art and about being black in both worlds.” So sin­gu­lar is Unti­tled that it became its own one-paint­ing show in 2018 when its new own­er sent it on a tour of the world, begin­ning in the artist’s home­town at the Brook­lyn Muse­um. Maesawa’s deci­sion to share the paint­ing presents a con­trast to the way Basquiat has been treat­ed dif­fer­ent­ly by oth­er own­ers of his work like Tiffany & Co., who explain their pur­chase and recent, con­tro­ver­sial com­mer­cial use of his Equals Pi by cit­ing his “affin­i­ty for the company’s state­ment blue col­or,” writes Tirhakah Love at Dai­ly Beast — a col­or they trade­marked ten years after Basquiat’s death.

The pro­pri­etary co-opta­tion of Basquiat’s life and work to sell sym­bols of colo­nial­ism like dia­monds, among oth­er lux­u­ry goods — and the turn­ing of his work into the ulti­mate lux­u­ry good — debas­es his pur­pos­es. Why show Equals Pi “as a prop to an ad?” asked his friend and for­mer room­mate Alex­is Adler. “Loan it out to a muse­um. In a time where there were very few Black artists rep­re­sent­ed in West­ern muse­ums, that was his goal: to get to a muse­um.” Find out in the Great Art Explained video how one of his most famous — and most expen­sive — works encap­su­lates that strug­gle through its vivid col­or and sym­bol­ic visu­al lan­guage.
