Musician Plays the Last Stradivarius Guitar in the World, the “Sabionari” Made in 1679

Last night, while the home team lost the big game on TVs at a local dive bar, my noisy rock band opened for a cham­ber pop ensem­ble. Elec­tric gui­tars and feed­back gave way to clas­si­cal acoustics, vio­lin, piano, accor­dion, and even a saw. It was an inter­est­ing cul­tur­al jux­ta­po­si­tion in an evening of cul­tur­al jux­ta­po­si­tions. The sports and music did­n’t gel, but an odd sym­me­try emerged from the two bands’ con­trast­ing styles, to a degree. The instru­ment above, on the oth­er hand, would have fit right in with the sec­ond act, whose old world charm would sure­ly find a place for a 1679 guitar—one craft­ed by the leg­endary mas­ter luthi­er Anto­nio Stradi­vari, no less.

If you know noth­ing at all about music or musi­cal instru­ments, you know the name Stradi­vari and the vio­lins that bear his name. They are such cov­et­ed, valu­able objects they some­times appear as the tar­get of crime capers in the movies and on tele­vi­sion. This Stradi­var­ius gui­tar, called the “Sabionari,” is even rar­er than the vio­lins. The Stradi­vari fam­i­ly, writes For­got­ten Gui­tar, “pro­duced over 1000 instru­ments, of which 960 were vio­lins.” Yet, “a small num­ber of gui­tars were also craft­ed, and as of today only one remains playable.” High­ly playable, you’ll observe in these videos, thanks to the restora­tion by luthiers Daniel Sinier, Fran­coise de Rid­der, and Loren­zo Frig­nani.

In the clip just above, Baroque con­cert gui­tarist Rolf Lisl­e­vand plays San­ti­a­go de Mur­ci­a’s “Taran­tela” on the restored gui­tar, whose sonorous ring­ing tim­bre recalls anoth­er Baroque instru­ment, the harp­si­chord.

So unique and unusu­al is the ten-string Stradi­var­ius Sabionari that it has its own web­site, where you’ll find many detailed, close-up pho­tos of the ele­gant design as well as more music, like the piece above, Ange­lo Michele Bar­tolot­ti’s Suite in G Minor as per­formed by clas­si­cal gui­tarist Krish­na­sol Jiménez, who, along with Lisl­e­vand, has been entrust­ed with the instru­ment for many live per­for­mances. Owned by a pri­vate col­lec­tor, the Sabionari very often appears at lec­tures on restora­tion and con­ser­va­tion of clas­si­cal instru­ments, as well as in per­for­mances around Europe. You’ll find on sabionari.com many more videos of the gui­tar in action (like that below of gui­tarist Ugo Nas­truc­ci impro­vis­ing), links to exhibits, descrip­tions of the chal­leng­ing­ly long neck and Baroque tun­ing, and a sense of just how much the Sabionari gets around for such a rare, antique instru­ment.

Ernst Haeckel’s Sublime Drawings of Flora & Fauna: The Beautiful Scientific Drawings That Influenced Europe’s Art Nouveau Movement (1889)

If you fol­low the ongo­ing beef many pop­u­lar sci­en­tists have with phi­los­o­phy, you’d be for­giv­en for think­ing the two dis­ci­plines have noth­ing to say to each oth­er. That’s a sad­ly false impres­sion, though they have become almost entire­ly sep­a­rate pro­fes­sion­al insti­tu­tions. But dur­ing the first, say, 200 years of mod­ern sci­ence, sci­en­tists were “nat­ur­al philosophers”—often as well versed in log­ic, meta­physics, or the­ol­o­gy as they were in math­e­mat­ics and tax­onomies. And most of them were artists too of one kind or anoth­er. Sci­en­tists had to learn to draw in order to illus­trate their find­ings before mass-pro­duced pho­tog­ra­phy and com­put­er imag­ing could do it for them. Many sci­en­tists have been fine artists indeed, rival­ing the greats, and they’ve made very fine musi­cians as well.

And then there’s Ernst Hein­rich Haeck­el, a Ger­man biol­o­gist and nat­u­ral­ist, philoso­pher and physi­cian, and pro­po­nent of Dar­win­ism who described and named thou­sands of species, mapped them on a genealog­i­cal tree, and “coined sev­er­al sci­en­tif­ic terms com­mon­ly known today,” This is Colos­sal writes, “such as ecol­o­gy, phy­lum, and stem cell.” That’s an impres­sive resume, isn’t it? Oh, and check out his art—his bril­liant­ly col­ored, ele­gant­ly ren­dered, high­ly styl­ized depic­tions of “far flung flo­ra and fau­na,” of microbes and nat­ur­al pat­terns, in designs that inspired the Art Nou­veau move­ment. “Each organ­ism Haeck­el drew has an almost abstract form,” notes Kather­ine Schwab at Fast Co. Design, “as if it’s a whim­si­cal fan­ta­sy he dreamed up rather than a real crea­ture he exam­ined under a micro­scope. His draw­ings of sponges reveal their intense­ly geo­met­ric structure—they look archi­tec­tur­al, like feats of engi­neer­ing.”

Haeck­el pub­lished 100 fab­u­lous prints begin­ning in 1889 in a series of ten books called Kun­st­for­men der Natur (“Art Forms in Nature”), col­lect­ed in two vol­umes in 1904. The aston­ish­ing work was “not just a book of illus­tra­tions but also the sum­ma­tion of his view of the world,” one which embraced the new sci­ence of Dar­win­ian evo­lu­tion whole­heart­ed­ly, writes schol­ar Olaf Brei­d­bach in his 2006 Visions of Nature.

Haeckel’s method was a holis­tic one, in which art, sci­ence, and phi­los­o­phy were com­ple­men­tary approach­es to the same sub­ject. He “sought to secure the atten­tion of those with an inter­est in the beau­ties of nature,” writes pro­fes­sor of zool­o­gy Rain­er Will­mann in a book from Taschen called The Art and Sci­ence of Ernst Haeck­el­, “and to empha­size, through this rare instance of the inter­play of sci­ence and aes­thet­ics, the prox­im­i­ty of these two realms.”

The gor­geous Taschen book includes 450 of Haeckel’s draw­ings, water­col­ors, and sketch­es, spread across 704 pages, and it’s expen­sive. But you can see all 100 of Haeckel’s orig­i­nal­ly pub­lished prints in zoomable high-res­o­lu­tion scans here. Or pur­chase a one-vol­ume reprint of the orig­i­nal Art Forms in Nature, with its 100 glo­ri­ous prints, through this Dover pub­li­ca­tion, which describes Haeckel’s art as “hav­ing caused the accep­tance of Dar­win­ism in Europe…. Today, although no one is great­ly inter­est­ed in Haeck­el the biol­o­gist-philoso­pher, his work is increas­ing­ly prized for some­thing he him­self would prob­a­bly have con­sid­ered sec­ondary.” It’s a shame his sci­en­tif­ic lega­cy lies neglect­ed, if that’s so, but it sure­ly lives on through his art, which may be just as need­ed now to illus­trate the won­ders of evo­lu­tion­ary biol­o­gy and the nat­ur­al world as it was in Haeckel’s time.

Revisit One of the Most Polarizing Albums in Rock History: Lou Reed’s Metal Machine Music, Which Came Out 50 Years Ago

Fifty years ago this month, Lou Reed near­ly destroyed his own career with one dou­ble album. Met­al Machine Music sold 100,000 copies dur­ing the three weeks of sum­mer 1975 between its release and its removal from the mar­ket. More than a few of the many buy­ers who prompt­ly returned it would have been expect­ing some­thing like Sal­ly Can’t Dance, Reed’s solo album from the pre­vi­ous year, whose slick­ly pro­duced songs went down eas­i­er than any­thing he’d record­ed with the Vel­vet Under­ground. What they heard when they put the new album on their turnta­bles (or insert­ed the Quadro­phon­ic 8‑track tape into their decks) was “noth­ing, absolute­ly noth­ing but scream­ing feed­back noise record­ed at var­i­ous fre­quen­cies, played back against var­i­ous oth­er noise lay­ers, split down the mid­dle into two total­ly sep­a­rate chan­nels of utter­ly inhu­man shrieks and hiss­es.”

That descrip­tion comes from vol­u­ble Creem rock crit­ic and avowed enthu­si­ast of deca­dence Lester Bangs, who also hap­pened to be one of Met­al Machine Music’s most fer­vent defend­ers. At one point he declared it “the great­est record ever made in the his­to­ry of the human eardrum.” (“Num­ber Two: Kiss Alive!”)

Much of what we know about the inten­tions behind this baf­fling album come from Bangs’ writ­ings, includ­ing those that pur­port to tran­scribe con­ver­sa­tions with Reed him­self, who’d been one of the crit­ic’s read­i­est ver­bal spar­ring part­ners. The inspi­ra­tion, as Reed explained to Bangs, came from lis­ten­ing to com­posers Ian­nis Xenakis and La Monte Young, who dared to go beyond the bound­aries of what most lis­ten­ers would con­sid­er music at all. Reed also insist­ed that he’d delib­er­ate­ly insert­ed bits and pieces of Mozart, Beethoven, and oth­er clas­si­cal mas­ters into his son­ic mael­strom, though Bangs clear­ly did­n’t buy it.

Met­al Machine Music does­n’t seem so weird now, does it?” asked an inter­view­er on Night Flight just a decade or so after the album’s release. “No, it does­n’t, does it?” Reed says. “In light of Eno and all this stuff that came out now, it’s not near­ly as insane and crazy as they said it was then.” Indeed, it sounds almost of a piece with an influ­en­tial work of ambi­ent music like Bri­an Eno’s Music for Air­ports, though that album was meant to calm its lis­ten­ers rather than dri­ve them from the room. Over the half-cen­tu­ry since its release, Met­al Machine Music has accrued enough appre­ci­a­tion to be paid trib­utes like the live per­for­mances by Ger­man ensem­ble Zeitkratzer that have con­tin­ued long after Reed’s death. The lega­cy of his “elec­tron­ic instru­men­tal com­po­si­tion,” as he said after one such con­cert in 2007, also includes a name­sake clause in record­ing con­tracts stip­u­lat­ing that “the artist must turn in a record that sound like the artist that the record com­pa­ny signed — not come in with Met­al Machine Music.”

How to Enter a ‘Flow State’ on Command: Peak Performance Mind Hack Explained in 7 Minutes

You can be for­giv­en for think­ing the con­cept of “flow” was cooked up and pop­u­lar­ized by yoga teach­ers. That word gets a lot of play when one is mov­ing from Down­ward-Fac­ing Dog on through War­rior One and Two.

Actu­al­ly, flow — the state of  “effort­less effort” — was coined by Goethe, from the Ger­man “rausch”, a dizzy­ing sort of ecsta­sy.

Friedrich Niet­zsche and psy­chol­o­gist William James both con­sid­ered the flow state in depth, but social the­o­rist Mihaly Csik­szent­mi­ha­lyi, author of Cre­ativ­i­ty: Flow and the Psy­chol­o­gy of Dis­cov­ery and Inven­tion, is the true giant in the field. Here’s one of his def­i­n­i­tions of flow:

Being com­plete­ly involved in an activ­i­ty for its own sake. The ego falls away. Time flies. Every action, move­ment, and thought fol­lows inevitably from the pre­vi­ous one, like play­ing jazz. Your whole being is involved, and you’re using your skills to the utmost.

Author Steven Kotler, Exec­u­tive Direc­tor of the Flow Research Col­lec­tive, not only seems to spend a lot of time think­ing about flow, as a lead­ing expert on human per­for­mance, he inhab­its the state on a fair­ly reg­u­lar basis, too.

Chalk it up to good luck?

Good genes? (Some researchers, includ­ing retired NIH geneti­cist Dean Hamer and psy­chol­o­gist C. Robert Cloninger, think genet­ics play a part…)

As Kotler points out above, any­one can hedge their bets by clear­ing away dis­trac­tions — all the usu­al bad­dies that inter­fere with sleep, per­for­mance, or pro­duc­tiv­i­ty.

It’s also impor­tant to know thy­self. Kotler’s an ear­ly bird, who gets crackin’ well before sun­rise:

I don’t just open my eyes at 4:00 AM, I try to go from bed to desk before my brain even kicks out of its Alpha wave state. I don’t check any emails. I turn every­thing off at the end of the day includ­ing unplug­ging my phones and all that stuff so that the next morn­ing there’s nobody jump­ing into my inbox or assault­ing me emo­tion­al­ly with some­thing, you know what I mean?… I real­ly pro­tect that ear­ly morn­ing time.

By con­trast, his night owl wife doesn’t start clear­ing the cob­webs ’til ear­ly evening.

In the above video for Big Think, Kotler notes that 22 flow trig­gers have been dis­cov­ered, pre-con­di­tions that keep atten­tion focused in the present moment.

His web­site lists many of those trig­gers:

  • Com­plete Con­cen­tra­tion in the Present Moment
  • Imme­di­ate Feed­back
  • Clear Goals
  • The Chal­lenge-Skills Ratio (ie: the chal­lenge should seem slight­ly out of reach
  • High con­se­quences 
  • Deep Embod­i­ment 
  • Rich Envi­ron­ment 
  • Cre­ativ­i­ty (specif­i­cal­ly, pat­tern recog­ni­tion, or the link­ing togeth­er of new ideas)

Kotler also shares Uni­ver­si­ty of North Car­oli­na psy­chol­o­gist Kei­th Sawyer’s trig­ger list for groups hop­ing to flow like a well-oiled machine:

  • Shared Goals
  • Close Lis­ten­ing 
  • “Yes And” (addi­tive, rather than com­bat­ive con­ver­sa­tions)
  • Com­plete Con­cen­tra­tion (total focus in the right here, right now)
  • A sense of con­trol (each mem­ber of the group feels in con­trol, but still)
  • Blend­ing Egos (each per­son can sub­merge their ego needs into the group’s)
  • Equal Par­tic­i­pa­tion (skills lev­els are rough­ly and equal every­one is involved)
  • Famil­iar­i­ty (peo­ple know one anoth­er and under­stand their tics and ten­den­cies)
  • Con­stant Com­mu­ni­ca­tion (a group ver­sion of imme­di­ate feed­back)
  • Shared, Group Risk

One might think peo­ple in the flow state would be float­ing around with an expres­sion of ecsta­t­ic bliss on their faces. Not so, accord­ing to Kotler. Rather, they tend to frown slight­ly. Good news for any­one with rest­ing bitch face!

(We’ll thank you to refer to it as rest­ing flow state face from here on out.)

Who Really Built the Egyptian Pyramids—And How Did They Do It?

Although it’s cer­tain­ly more plau­si­ble than hypothe­ses like ancient aliens or lizard peo­ple, the idea that slaves built the Egypt­ian pyra­mids is no more true. It derives from cre­ative read­ings of Old Tes­ta­ment sto­ries and tech­ni­col­or Cecil B. Demille spec­ta­cles, and was a clas­sic whataboutism used by slav­ery apol­o­gists. The notion has “plagued Egypt­ian schol­ars for cen­turies,” writes Eric Betz at Dis­cov­er. But, he adds emphat­i­cal­ly, “Slaves did not build the pyra­mids.” Who did?

The evi­dence sug­gests they were built by a force of skilled labor­ers, as the Ver­i­ta­si­um video above explains. These were cadres of elite con­struc­tion work­ers who were well-fed and housed dur­ing their stint. “Many Egyp­tol­o­gists,” includ­ing archae­ol­o­gist Mark Lehn­er, who has exca­vat­ed a city of work­ers in Giza, “sub­scribe to the hypothe­ses that the pyra­mids were… built by a rotat­ing labor force in a mod­u­lar, team-based kind of orga­ni­za­tion,” Jonathan Shaw writes at Har­vard Mag­a­zine. Graf­fi­ti dis­cov­ered at the site iden­ti­fies team names like “Friends of Khu­fu” and “Drunk­ards of Menkau­re.”

The exca­va­tion also uncov­ered “tremen­dous quan­ti­ties of cat­tle, sheep, and goat bone, ‘enough to feed sev­er­al thou­sand peo­ple, even if they ate meat every day,’ adds Lehn­er,” sug­gest­ing that work­ers were “fed like roy­al­ty.” Anoth­er exca­va­tion by Lehner’s friend Zahi Hawass, famed Egypt­ian archae­ol­o­gist and expert on the Great Pyra­mid, has found work­er ceme­ter­ies at the foot of the pyra­mids, mean­ing that those who per­ished were buried in a place of hon­or. This was incred­i­bly haz­ardous work, and the peo­ple who under­took it were cel­e­brat­ed and rec­og­nized for their achieve­ment.

Labor­ers were also work­ing off an oblig­a­tion, some­thing every Egypt­ian owed to those above them and, ulti­mate­ly, to their pharaoh. But it was not a mon­e­tary debt. Lehn­er describes what ancient Egyp­tians called bak, a kind of feu­dal duty. While there were slaves in Egypt, the builders of the pyra­mids were maybe more like the Amish, he says, per­form­ing the same kind of oblig­a­tory com­mu­nal labor as a barn rais­ing. In that con­text, when we look at the Great Pyra­mid, “you have to say ‘This is a hell of a barn!’’’

The evi­dence unearthed by Lehn­er, Hawass, and oth­ers has “dealt a seri­ous blow to the Hol­ly­wood ver­sion of a pyra­mid build­ing,” writes Shaw, “with Charl­ton Hes­ton as Moses inton­ing, ‘Pharaoh, let my peo­ple go!’” Recent arche­ol­o­gy has also dealt a blow to extrater­res­tri­al or time-trav­el expla­na­tions, which begin with the assump­tion that ancient Egyp­tians could not have pos­sessed the know-how and skill to build such struc­tures over 4,000 years ago. Not so. Ver­i­ta­si­um explains the incred­i­ble feats of mov­ing the out­er stones with­out wheels and trans­port­ing the gran­ite core of the pyra­mids 620 miles from its quar­ry to Giza.

Ancient Egyp­tians could plot direc­tions on the com­pass, though they had no com­pass­es. They could make right angles and lev­els and thus had the tech­nol­o­gy required to design the pyra­mids. What about dig­ging up the Great Pyramid’s 2 mil­lion blocks of yel­low lime­stone? As we know, this was done by a skilled work­force, who quar­ried an “Olympic swimming-pool’s worth of stone every eight days” for 23 years to build the Great Pyra­mid, notes Joe Han­son in the PBS It’s Okay to Be Smart video above. They did so using the only met­al avail­able to them, cop­per.

This may sound incred­i­ble, but mod­ern exper­i­ments have shown that this amount of stone could be quar­ried and moved, using the tech­nol­o­gy avail­able, by a team of 1,200 to 1,500 work­ers, around the same num­ber of peo­ple archae­ol­o­gists believe to have been on-site dur­ing con­struc­tion. The lime­stone was quar­ried direct­ly at the site (in fact the Sphinx was most­ly dug out of the earth, rather than built atop it). How was the stone moved? Egyp­tol­o­gists from the Uni­ver­si­ty of Liv­er­pool think they may have found the answer, a ramp with stairs and a series of holes which may have been used as a pul­ley sys­tem.

Learn more about the myths and the real­i­ties of the builders of Egypt’s pyra­mids in the It’s Okay to Be Smart “Who Built the Pyra­mids, Part 1″ video above.

How Medieval Islamic Engineering Brought Water to the Alhambra

Between 711 and 1492, much of the Iber­ian Penin­su­la, includ­ing mod­ern-day Spain, was under Mus­lim rule. Not that it was easy to hold on to the place for that length of time: after the fall of Tole­do in 1085, Al-Andalus, as the ter­ri­to­ry was called, con­tin­ued to lose cities over the sub­se­quent cen­turies. Cór­do­ba and Seville were recon­quered prac­ti­cal­ly one right after the oth­er, in 1236 and 1248, respec­tive­ly, and you can see the inva­sion of the first city ani­mat­ed in the open­ing scene of the Pri­mal Space video above. “All over the land, Mus­lim cities were being con­quered and tak­en over by the Chris­tians,” says the com­pan­ion arti­cle at Pri­mal Neb­u­la. “But amidst all of this, one city remained uncon­quered, Grana­da.”

“Thanks to its strate­gic posi­tion and the enor­mous Alham­bra Palace, the city was pro­tect­ed,” and there the Alham­bra remains today. A “thir­teenth-cen­tu­ry pala­tial com­plex that’s one of the world’s most icon­ic exam­ples of Moor­ish archi­tec­ture,” writes BBC.com’s Esme Fox, it’s also a land­mark feat of engi­neer­ing, boast­ing “one of the most sophis­ti­cat­ed hydraulic net­works in the world, able to defy grav­i­ty and raise water from the riv­er near­ly a kilo­me­ter below.”

The jew­el in the crown of these elab­o­rate water­works is a white mar­ble foun­tain that “con­sists of a large dish held up by twelve white myth­i­cal lions. Each beast spurts water from its mouth, feed­ing four chan­nels in the patio’s mar­ble floor that rep­re­sent the four rivers of par­adise, and then run­ning through­out the palace to cool the rooms.”

The fuente de los Leones also tells time: the num­ber of lions cur­rent­ly indi­cates the hour. This works thanks to an inge­nious design explained both ver­bal­ly and visu­al­ly in the video. Any­one vis­it­ing the Alham­bra today can admire this and oth­er exam­ples of medieval opu­lence, but trav­el­ers with an engi­neer’s cast of mind will appre­ci­ate even more how the palace’s builders got the water there at all. “The hill was around 200 meters above Granada’s main riv­er,” says the nar­ra­tor, which entailed an ambi­tious project of damming and redi­rec­tion, to say noth­ing of the pool above the palace designed to keep the whole hydraulic sys­tem pres­sur­ized. The Alham­bra’s heat­ed baths and well-irri­gat­ed gar­dens rep­re­sent the lux­u­ri­ous height of Moor­ish civ­i­liza­tion, but they also remind us that, then as now, beneath every lux­u­ry lies an impres­sive feat of tech­nol­o­gy.

Gen­er­a­tive AI is rapid­ly becom­ing an essen­tial tool for stream­lin­ing work and solv­ing com­plex chal­lenges. How­ev­er, know­ing how to use GenAI effec­tive­ly isn’t always obvi­ous. That’s where Google Prompt­ing Essen­tials comes in. This course will teach you to write clear and spe­cif­ic instructions—known as prompts—for AI. Once you can prompt well, you can unlock gen­er­a­tive AI’s poten­tial more ful­ly.

Launched in April, Google Prompt­ing Essen­tials has become the most pop­u­lar GenAI course offered on Cours­era. The course itself is divid­ed into four mod­ules. First, “Start Writ­ing Prompts Like a Pro” will teach you a 5‑step method for craft­ing effec­tive prompts. (Watch the video from Mod­ule 1 above, and more videos here.) With the sec­ond mod­ule, “Design Prompts for Every­day Work Tasks,” you will learn how to use AI to draft emails, brain­storm ideas, and sum­ma­rize doc­u­ments. The third mod­ule, “Speed Up Data Analy­sis and Pre­sen­ta­tion Build­ing,” teach­es tech­niques for uncov­er­ing insights in data, visu­al­iz­ing results, and prepar­ing pre­sen­ta­tions. The final mod­ule, “Use AI as a Cre­ative or Expert Part­ner,” explores advanced tech­niques such as prompt chain­ing and mul­ti­modal prompt­ing. Plus, you will “cre­ate a per­son­al­ized AI agent to role-play con­ver­sa­tions and pro­vide expert feed­back.”

Offered on the Cours­era plat­form, Google Prompt­ing Essen­tials costs $49. Once you com­plete the course, you will receive a cer­tifi­cate from Google to share with your net­work and employ­er. Bet­ter yet, you will under­stand how to make GenAI a more use­ful tool in your life and work. Enroll here.

Solving a 2,500-Year-Old Puzzle: How a Cambridge Student Cracked an Ancient Sanskrit Code

If you find your­self grap­pling with an intel­lec­tu­al prob­lem that’s gone unsolved for mil­len­nia, try tak­ing a few months off and spend­ing them on activ­i­ties like swim­ming and med­i­tat­ing. That very strat­e­gy worked for a Cam­bridge PhD stu­dent named Rishi Rajpopat, who, after a sum­mer of non-research-relat­ed activ­i­ties, returned to a text by the ancient gram­mar­i­an, logi­cian, and “father of lin­guis­tics” Pāṇi­ni and found it new­ly com­pre­hen­si­ble. The rules of its com­po­si­tion had stumped schol­ars for 2,500 years, but, as Rajpopat tells it in an arti­cle by Tom Almeroth-Williams at Cam­bridge’s web­site, “With­in min­utes, as I turned the pages, these pat­terns start­ed emerg­ing, and it all start­ed to make sense.”

Pāṇi­ni com­posed his texts using a kind of algo­rithm: “Feed in the base and suf­fix of a word and it should turn them into gram­mat­i­cal­ly cor­rect words and sen­tences through a step-by-step process,” writes Almeroth-Williams. But “often, two or more of Pāṇini’s rules are simul­ta­ne­ous­ly applic­a­ble at the same step, leav­ing schol­ars to ago­nize over which one to choose.” Or such was the case, at least, before Rajpopat’s dis­cov­ery that the dif­fi­cult-to-inter­pret “metarule” meant to apply to such cas­es dic­tates that “between rules applic­a­ble to the left and right sides of a word respec­tive­ly, Pāṇi­ni want­ed us to choose the rule applic­a­ble to the right side.”

That may not be imme­di­ate­ly under­stand­able to those unfa­mil­iar with the struc­ture of San­skrit. Almeroth-Williams’ piece clar­i­fies with an exam­ple using  mantra, one word from the lan­guage that every­body knows. “In the sen­tence ‘devāḥ prasan­nāḥ mantraiḥ’ (‘The Gods [devāḥ] are pleased [prasan­nāḥ] by the mantras [mantraiḥ]’) we encounter ‘rule con­flict’ when deriv­ing mantraiḥ, ‘by the mantras,’ ” he writes. ” The deriva­tion starts with ‘mantra + bhis. One rule is applic­a­ble to the left part ‘mantra’ and the oth­er to right part ‘bhis.’ We must pick the rule applic­a­ble to the right part ‘bhis,’ which gives us the cor­rect form ‘mantraih.’ ”

Apply­ing this rule ren­ders inter­pre­ta­tions of Pāṇini’s work almost com­plete­ly unam­bigu­ous and gram­mat­i­cal. It could even be employed, Rajpopat has not­ed, to teach San­skrit gram­mar to com­put­ers being pro­grammed for nat­ur­al lan­guage pro­cess­ing. It no doubt took him a great deal of inten­sive study to reach the point where he was able to dis­cov­er the true mean­ing of Pāṇini’s clar­i­fy­ing metarule, but it did­n’t tru­ly present itself until he let his uncon­scious mind take a crack at it. As we’ve said here on Open Cul­ture before, there are good rea­sons we do our best think­ing while doing things like walk­ing or tak­ing a show­er, a phe­nom­e­non that philoso­phers have broad­ly rec­og­nized through the ages — and, like as not, was under­stood by the great Pāṇi­ni him­self.

Jimi Hendrix Arrives in London in 1966, Asks to Get Onstage with Cream, and Blows Eric Clapton Away: “You Never Told Me He Was That F‑ing Good”

Jimi Hen­drix arrived on the Lon­don scene like a ton of bricks in 1966, smash­ing every British blues gui­tarist to pieces the instant they saw him play. As vocal­ist Ter­ry Reid tells it, when Hen­drix played his first show­case at the Bag O’Nails, arranged by Ani­mals’ bassist Chas Chan­dler, “there were gui­tar play­ers weep­ing. They had to mop the floor up. He was pil­ing it on, solo after solo. I could see everyone’s fill­ings falling out. When he fin­ished, it was silence. Nobody knew what to do. Every­body was dumb­struck, com­plete­ly in shock.”

He only exag­ger­ates a lit­tle, by all accounts, and when Reid says “every­body,” he means every­body: Kei­th Richards, Mick Jag­ger, Bri­an Jones, Jeff Beck, Paul McCart­ney, The Who, Eric Bur­don, John May­all, and maybe Jim­my Page, though he denies it. May­all recalls, “the buzz was out before Jimi had even been seen here, so peo­ple were antic­i­pat­ing his per­for­mance, and he more than lived up to what we were expect­ing.” In fact, even before this leg­endary event sent near­ly every star clas­sic rock gui­tarist back to the wood­shed, Jimi had arrived unan­nounced at the Regent Street Poly­tech­nic, and asked to sit in and jam with Cream, where he pro­ceed­ed to dethrone the reign­ing British gui­tar god, Eric Clap­ton.

Nobody knew who he was, but “in those days any­body could get up with any­body,” Clap­ton says in a recent inter­view, “if you were con­vinc­ing enough that you could play. He got up and blew everyone’s mind.” As Hen­drix biog­ra­ph­er Charles Cross tells it, “no one had ever asked to jam” with Cream before. “Most would have been too intim­i­dat­ed by their rep­u­ta­tion as the best band in Britain.” To hear the sto­ry as it’s told in the clip above from the BBC doc­u­men­tary Sev­en Ages of Rock, no one else would have ever dared to get onstage with Eric Clap­ton. Clap­ton, as the famed graf­fi­ti in Lon­don announced, was God. “It was a very brave per­son who would do that,” says Jack Bruce.

Actu­al­ly, it was Chan­dler who asked the band, and who also tried to pre­pare Clap­ton. Jimi got onstage, plugged into Bruce’s bass amp, and played a ver­sion of Howl­in’ Wolf’s “Killin’ Floor.” Every­one was “com­plete­ly gob­s­macked,” Clap­ton writes in his auto­bi­og­ra­phy. “I remem­ber think­ing that here was a force to be reck­oned with. It scared me, because he was clear­ly going to be a huge star, and just as we are find­ing our own speed, here was the real thing.” Fear, envy, awe… all rea­son­able emo­tions when stand­ing next to Jimi Hen­drix as he tears through “Killin’ Floor” three times faster than any­one else played it (as you can see him play it in Stock­holm above)—while doing the splits, lying on the floor, play­ing with his teeth and behind his head…

“It was amaz­ing,” writes Clap­ton, “and it was musi­cal­ly great, too, not just pyrotech­nics.” There’s no telling how Jimi might have remem­bered the event had he lived to write his mem­oirs, but he would have been pret­ty mod­est, as was his way. No one else who saw him felt any need to hold back. “It must have been dif­fi­cult for Eric to han­dle,” says Bruce, “because [Eric] was ‘God,’” and this unknown per­son comes along, and burns.” He puts it slight­ly dif­fer­ent­ly at the top: “Eric was a gui­tar play­er. Jimi was some sort of force of nature.”

Rock jour­nal­ist Kei­th Altham has yet a third account, as Ed Vul­liamy writes at The Guardian. He remem­bers “Chan­dler going back­stage after Clap­ton left in the mid­dle of the song ‘which he had yet to mas­ter him­self’; Clap­ton was furi­ous­ly puff­ing on a cig­a­rette and telling Chas: ‘You nev­er told me he was that fuck­ing good.’” Who knows if Hen­drix knew Clap­ton had strug­gled with “Killin’ Floor” and decid­ed not to try it live. But as blues gui­tarist Stephen Dale Petit notes, “when Chas invit­ed Jimi to Lon­don, Jimi did not ask about mon­ey or con­tracts. He asked if Chas would intro­duce him to Beck and Clap­ton.”

He had come to meet, and blow away, his rock heroes. “Two weeks after The Bag O’Nails,” writes Clas­sic Rock’s John­ny Black, “when Cream appeared at The Mar­quee Club, Clap­ton was sport­ing a frizzy perm and he left his gui­tar feed­ing back against the amp, just as he’d seen Jimi do.”

J. G. Ballard Demystifies Surrealist Paintings by Dalí, Magritte, de Chirico & More

Before his sig­na­ture works like The Atroc­i­ty Exhi­bi­tion, Crash, and High-Rise, J. G. Bal­lard pub­lished three apoc­a­lyp­tic nov­els, The Drowned World, The Burn­ing World, and The Crys­tal World. Each of those books offers a dif­fer­ent vision of large-scale envi­ron­men­tal dis­as­ter, and the last even pro­vides a clue as to its inspi­ra­tion. Or rather, its orig­i­nal cov­er does, by using a sec­tion of Max Ern­st’s paint­ing The Eye of Silence. “This spinal land­scape, with its fren­zied rocks tow­er­ing into the air above the silent swamp, has attained an organ­ic life more real than that of the soli­tary nymph sit­ting in the fore­ground,” Bal­lard writes in “The Com­ing of the Uncon­scious,” an arti­cle on sur­re­al­ism writ­ten short­ly after The Crys­tal World appeared in 1966.

First pub­lished in an issue of the mag­a­zine New Worlds (which also con­tains Bal­lard’s take on Chris Mark­er’s La Jetée), the piece is osten­si­bly a review of Patrick Wald­berg’s Sur­re­al­ism and Mar­cel Jean’s The His­to­ry of Sur­re­al­ist Paint­ing, but it ends up deliv­er­ing Bal­lard’s short analy­ses of a series of paint­ings by var­i­ous sur­re­al­ist mas­ters.

The Eye of Silence shows the land­scapes of our world “for what they are — the palaces of flesh and bone that are the liv­ing facades enclos­ing our own sub­lim­i­nal con­scious­ness.” The “ter­ri­fy­ing struc­ture” at the cen­ter of René Magritte’s The Annun­ci­a­tion is “a neu­ron­ic totem, its round­ed and con­nect­ed forms are a frag­ment of our own ner­vous sys­tems, per­haps an insol­u­ble code that con­tains the oper­at­ing for­mu­lae for our own pas­sage through time and space.”

In Gior­gio de Chiri­co’s The Dis­qui­et­ing Mus­es, “an unde­fined anx­i­ety has begun to spread across the desert­ed square. The sym­me­try and reg­u­lar­i­ty of the arcades con­ceals an intense inner vio­lence; this is the face of cata­ton­ic with­draw­al”; its fig­ures are “human beings from whom all tran­si­tion­al time has been erod­ed.” Anoth­er work depicts an emp­ty beach as “a sym­bol of utter psy­chic alien­ation, of a final sta­sis of the soul”; its dis­place­ment of beach and sea through time “and their mar­riage with our own four-dimen­sion­al con­tin­u­um, has warped them into the rigid and unyield­ing struc­tures of our own con­scious­ness.” There Bal­lard writes of no less famil­iar a can­vas than The Per­sis­tence of Mem­o­ry by Sal­vador Dalí, whom he called “the great­est painter of the twen­ti­eth cen­tu­ry” more than 40 years after “The Com­ing of the Uncon­scious” in the Guardian.

A decade there­after, that same pub­li­ca­tion’s Declan Lloyd the­o­rizes that the exper­i­men­tal bill­boards designed by Bal­lard in the fifties (pre­vi­ous­ly fea­tured here on Open Cul­ture) had been tex­tu­al rein­ter­pre­ta­tions of Dalí’s imagery. Until the late six­ties, Bal­lard says in a 1995 World Art inter­view, “the Sur­re­al­ists were very much looked down upon. This was part of their attrac­tion to me, because I cer­tain­ly did­n’t trust Eng­lish crit­ics, and any­thing they did­n’t like seemed to me prob­a­bly on the right track. I’m glad to say that my judg­ment has been seen to be right — and theirs wrong.” He under­stood the long-term val­ue of Sur­re­al­ist visions, which had seem­ing­ly been obso­lesced by World War II before, “all too soon, a new set of night­mares emerged.” We can only hope he won’t be proven as pre­scient about the long-term hab­it­abil­i­ty of the plan­et.
