How Ancient Scrolls, Charred by the Eruption of Mount Vesuvius in 79 AD, Are Now Being Read by Particle Accelerators, 3D Modeling & Artificial Intelligence

Every­one knows that Mount Vesu­vius erupt­ed in 79 AD, entomb­ing the Roman town of Pom­peii in ash. Almost every­one knows that it also did the same to sev­er­al oth­er towns, includ­ing wealthy Her­cu­la­neum on the Bay of Naples. Count­less schol­ars have ded­i­cat­ed their lives to study­ing these unusu­al­ly well-pre­served first-cen­tu­ry ruins and the his­tor­i­cal trea­sures found with­in. We now under­stand a great deal about the lay­out, the struc­tures, the social life of Her­cu­la­neum, but some aspects remain unknow­able, such as the con­tents of the scrolls, charred beyond recog­ni­tion, that fill its libraries — or at least that remained unknow­able until now.

“In the 18th cen­tu­ry, work­men employed by King Charles III of Spain, then in charge of much of south­ern Italy, dis­cov­ered the remains of a mag­nif­i­cent vil­la, thought to have belonged to Lucius Calpurnius Piso Caeson­i­nus (known as Piso), a wealthy states­man and the father-in-law of Julius Cae­sar,” writes Smith­son­ian’s Jo Marchant. There, “in what was to become one of the most frus­trat­ing archae­o­log­i­cal dis­cov­er­ies ever, the work­men also found approx­i­mate­ly 2,000 papyrus scrolls.” But since the heat and gas­es of Vesu­vius had turned them “black and hard like lumps of coal”  — and indeed, some of Charles III’s work­men mis­took them for coal and threw them away — attempts to open them “cre­at­ed a mess of frag­ile flakes that yield­ed only brief snip­pets of text.”

The time of Charles III bare­ly had suf­fi­cient know-how to avoid destroy­ing the scrolls of Her­cu­la­neum, let alone to read them. That task turns out to demand even the most cut­ting-edge tech­nol­o­gy we have today, includ­ing cus­tom-made 3D mod­el­ing soft­ware, arti­fi­cial intel­li­gence, and the most advanced x‑ray facil­i­ties in exis­tence. Marchan­t’s arti­cle focus­es on an Amer­i­can com­put­er sci­en­tist named Brent Seales (Pro­fes­sor and Chair of Com­put­er Sci­ence at the Uni­ver­si­ty of Ken­tucky), whose quest to read the Her­cu­la­neum scrolls has become a quest to devel­op a method to vir­tu­al­ly “unroll” them. This requires not just the com­put­ing pow­er and log­ic to deter­mine how these black­ened lumps (Seales calls two of them “Fat Bas­tard” and “Banana Boy”) might orig­i­nal­ly have opened up, but the most advanced par­ti­cle accel­er­a­tors in the world to scan them in the first place.

You can read more about Seales’ work with the Her­cu­la­neum scrolls, which after twen­ty years has shown real promise, at Men­tal Floss and Newsweek. Though quite expen­sive (demand for “beam time” on a par­ti­cle accel­er­a­tor being what it is), huge­ly time-con­sum­ing, and occa­sion­al­ly, in Seales’ words, “excru­ci­at­ing­ly frus­trat­ing,” the inven­tion of a reli­able method for read­ing these and oth­er seem­ing­ly lost texts from antiq­ui­ty could make sub­stan­tial addi­tions to what we think of as the canon. (The texts revealed so far have had to do with the ideas of Epi­cu­rus, a primer on whose phi­los­o­phy we’ve pre­vi­ous­ly fea­tured on Open Cul­ture.) But gain­ing the fullest pos­si­ble under­stand­ing of what our ances­tors knew in the first cen­tu­ry may first require a few more 21st-cen­tu­ry devel­op­ments in physics and com­put­er sci­ence yet.

Jocelyn Bell Burnell Discovered Radio Pulsars in 1974, But the Credit Went to Her Advisor; In 2018, She Gets Her Due, Winning a $3 Million Physics Prize

Say you made a Nobel-wor­thy sci­en­tif­ic dis­cov­ery and the prize went to your the­sis super­vi­sor instead. How would you take it? Prob­a­bly not as well as Joce­lyn Bell Bur­nell, dis­cov­er­er of the first radio pul­sars, to whom that very thing hap­pened in 1974. “Demar­ca­tion dis­putes between super­vi­sor and stu­dent are always dif­fi­cult, prob­a­bly impos­si­ble to resolve,” she said a few years lat­er. “It is the super­vi­sor who has the final respon­si­bil­i­ty for the suc­cess or fail­ure of the project. We hear of cas­es where a super­vi­sor blames his stu­dent for a fail­ure, but we know that it is large­ly the fault of the super­vi­sor. It seems only fair to me that he should ben­e­fit from the suc­cess­es, too.”

But now, 44 years lat­er, Bell Bur­nel­l’s achieve­ment has brought a dif­fer­ent prize her way: the Spe­cial Break­through Prize in Fun­da­men­tal Physics, to be pre­cise, and the $3 mil­lion that comes with it, all of which she will donate “to fund women, under-rep­re­sent­ed eth­nic minor­i­ty and refugee stu­dents to become physics researchers.” “Like the stars of Hid­den Fig­ures and DNA researcher Ros­alind Franklin, Bell Burnell’s per­son­al sto­ry embod­ies the chal­lenges faced by women in sci­en­tif­ic fields,” write the Wash­ing­ton Post’s Sarah Kaplan and Anto­nia Noori Farzan. “Bell Bur­nell, who was born in North­ern Ire­land in 1943, had to fight to take sci­ence class­es after age 12.”

Reject­ing an expect­ed life of cook­ery and needle­work, Bell Bur­nell “read her father’s astron­o­my books cov­er to cov­er, teach­ing her­self the jar­gon and grap­pling with com­plex con­cepts until she felt she could com­pre­hend the uni­verse. She com­plained to her par­ents, who com­plained to the school, which ulti­mate­ly allowed her to attend lab along with two oth­er girls. At the end of the semes­ter, Bell Bur­nell ranked first in the class.” Still, by the time she arrived at Cam­bridge Uni­ver­si­ty for grad­u­ate school, she “was cer­tain some­one had made a mis­take admit­ting her.” Her sub­se­quent work there on one of “the most impor­tant astro­nom­i­cal finds of the 20th cen­tu­ry,” which you can see her talk about in the clip above, should have dis­pelled that notion.

But as Josh Jones wrote here on Open Cul­ture last month, Bell Bur­nell was a vic­tim of the “Matil­da effect,” named for suf­frag­ist and abo­li­tion­ist Matil­da Joslyn Gage, which iden­ti­fies the “denial of recog­ni­tion to women sci­en­tists” seen through­out the his­to­ry of sci­ence. The new gen­er­a­tion of prizes like the Break­through Prize in Fun­da­men­tal Physics, found­ed in 2012 by physi­cist-entre­pre­neur Yuri Mil­ner, have the poten­tial to coun­ter­act the Matil­da effect, but many oth­er Matil­das have yet to be rec­og­nized. “I am not myself upset about it,” as Bell Bur­nell put it in 1977 when asked about her non-recep­tion of the Nobel. “After all, I am in good com­pa­ny, am I not!”

MIT Students Solve the Spaghetti Breaking Mystery That Stumped Richard Feynman

Even thir­ty years after his death, Richard Feyn­man remains one of the most beloved minds in physics in part because of how much atten­tion he paid to things oth­er than physics: draw­ing and paint­ingcrack­ing safes, play­ing the bon­gos, break­ing spaghet­ti. But a physics enthu­si­ast might object, and rea­son­ably so, that all those activ­i­ties actu­al­ly have a great deal to do with physics, giv­en the phys­i­cal phe­nom­e­na they all demon­strate and on which they all depend. In recent years, con­sid­er­able sci­en­tif­ic atten­tion has even gone toward spaghet­ti-break­ing, inspir­ing as it did Feyn­man — and com­put­er sci­en­tist Dan­ny Hillis, who hap­pened to be in the kitchen with him — to pose a long-unan­swer­able ques­tion: How come it always breaks into a mil­lion pieces when you snap it?

Maybe spaghet­ti does­n’t always break into a mil­lion pieces, exact­ly, but it nev­er breaks in two. Dis­cov­er­ing the secret to a clean two-part break did require a mil­lion of some­thing: a mil­lion frames per sec­ond, specif­i­cal­ly, shot by a cam­era aimed at a pur­pose-built spaghet­ti-break­ing device. The results of the research, a project of stu­dents Ronald Heiss­er and Vishal Patil dur­ing their time at MIT, came out in a paper co-authored by MIT’s Nor­bert Stoop and Uni­ver­sité Aix Mar­seille’s Emmanuel Viller­maux, just pub­lished in the Pro­ceed­ings of the Nation­al Acad­e­my of Sci­ences. The team found, writes MIT News’ Jen­nifer Chu, “that if a stick [of spaghet­ti] is twist­ed past a cer­tain crit­i­cal degree, then slow­ly bent in half, it will, against all odds, break in two.”

As for why spaghet­ti breaks into so many pieces with­out the twist, a ques­tion tak­en on by the Smarter Every Day video just above, French sci­en­tists Basile Audoly and Sebastien Neukirch won the Ig Nobel Prize by fig­ur­ing that out in 2005: “When a stick is bent even­ly from both ends, it will break near the cen­ter, where it is most curved. This ini­tial break trig­gers a ‘snap-back’ effect and a bend­ing wave, or vibra­tion, that fur­ther frac­tures the stick.” If you twist the stick first, “the snap-back, in which the stick will spring back in the oppo­site direc­tion from which it was bent, is weak­ened in the pres­ence of twist. And, the twist-back, where the stick will essen­tial­ly unwind to its orig­i­nal straight­ened con­fig­u­ra­tion, releas­es ener­gy from the rod, pre­vent­ing addi­tion­al frac­tures.”

So now we know. But the fruits of what might strike some as an obses­sive and point­less quest could well fur­ther the sci­ence of frac­tur­ing, which Patil describes to the Wash­ing­ton Post as an out­ward­ly “chaot­ic and ran­dom” process. This research could lead, as Chu writes, to a bet­ter “under­stand­ing of crack for­ma­tion and how to con­trol frac­tures in oth­er rod-like mate­ri­als such as mul­ti­fiber struc­tures, engi­neered nan­otubes, or even micro­tubules in cells.” That’s all a long way from the kitchen, cer­tain­ly, but even the most rev­o­lu­tion­ary advance­ments of knowl­edge grow out of sim­ple curios­i­ty, an impulse felt even in the most mun­dane or friv­o­lous sit­u­a­tions. Richard Feyn­man under­stood that bet­ter than most, hence sub­se­quent gen­er­a­tions of sci­en­tists’ desire to pick up what­ev­er piqued his inter­est — even bro­ken bits of Bar­il­la No. 5.

Steve Martin & Robin Williams Riff on Math, Physics, Einstein & Picasso in a Smart Comedy Routine

Back in 2002, Stan­ford Uni­ver­si­ty math­e­mat­ics pro­fes­sor Robert Osser­man chat­ted with come­di­an and ban­jo play­er extra­or­di­naire Steve Mar­tin in San Francisco’s Herb­st The­atre. The event was called “Fun­ny Num­bers” and it was intend­ed to deliv­er an off-kil­ter dis­cus­sion on math. Boy did it deliv­er.

The first half of the dis­cus­sion was loose and relaxed. Mar­tin talked about his writ­ing, ban­jos and his child­hood inter­est in math. “In high school, I used to be able to make mag­ic squares,” said Mar­tin. “I like any­thing kind of ‘jumbly.’ I like ana­grams. What else do I like? I like sex.”

Then Robin Williams, that man­ic ball of ener­gy, showed up. As you can see from the five videos through­out this post, the night quick­ly spi­raled into com­ic mad­ness.

They riffed on the Osbournes, Hen­ry Kissinger, num­ber the­o­ry, and physics. “Schrödinger, pick up your cat,” barks Williams at the end of a par­tic­u­lar­ly inspired tear. “He’s alive. He’s dead. What a pet!”

When Mar­tin and Williams read pas­sages from Martin’s hit play, Picas­so at the Lapin Agile Williams read his part at dif­fer­ent points as if he were Mar­lon Bran­do, Peter Lorre and Elmer Fudd. At anoth­er time, Williams and Mar­tin riffed on the num­ber zero. Williams, for once act­ing as the straight man, asked Osser­man, “I have one quick ques­tion, up to the Cru­sades, the num­ber zero did­n’t exist, right? In West­ern civ­i­liza­tion.” To which Mar­tin bel­lowed, “That is a lie! How dare you imply that the num­ber zero…oh, I think he’s right.”

The videos are weird­ly glitchy, though the audio is just fine. And the com­e­dy is com­plete­ly hilar­i­ous and sur­pris­ing­ly thought pro­vok­ing.

Newly Unearthed Footage Shows Albert Einstein Driving a Flying Car (1931)

Dur­ing his life­time, Albert Ein­stein appar­ent­ly nev­er learned to dri­ve a car–some­thing that also held true for Vladimir Nabokov, Ray Brad­bury, Eliz­a­beth Bish­op, and Jack Ker­ouac. But he did man­age to expe­ri­ence the thrill of get­ting behind the wheel, at least once. Above, watch a new­ly-dis­cov­ered home movie of Ein­stein and his sec­ond wife, Elsa, vis­it­ing the Warn­er Bros. sound­stage on Feb­ru­ary 3, 1931. The fol­low­ing day, The New York Times pub­lished this report:

Pro­fes­sor Ein­stein was sur­prised tonight into loud and long laugh­ter.

Hol­ly­wood demon­strat­ed its prin­ci­ples of “rel­a­tiv­i­ty,” how it makes things seem what they are not, by use of a dilap­i­dat­ed motor car.

At the First Nation­al stu­dio, Ger­man tech­ni­cians per­suad­ed Pro­fes­sor Ein­stein to change his mind about not being pho­tographed and pho­tographed him in the old car with Frau Elsa, his wife. He can­not dri­ve a car.

Tonight the Ger­man tech­ni­cians brought the film to the Ein­stein bun­ga­low. The lights went out.

Then the ancient auto­mo­bile appeared on the screen with Ein­stein at the wheel, dri­ving Frau Elsa on a sight-see­ing tour.

Down Broad­way, Los Ange­les they drove, then to the beach­es. Sud­den­ly the car rose like an air­plane, and as Ein­stein took one hand from the wheel to point out the scenery, the Rocky Moun­tains appeared below. Then the car land­ed on famil­iar soil and the dri­ve con­tin­ued through Ger­many.

It was just a Hol­ly­wood trick of dou­ble expo­sure and a thrilling com­e­dy, but not for the pub­lic. The mas­ter film was destroyed, and the only copy was giv­en to the Ein­steins.

That one sur­viv­ing copy of the film even­tu­al­ly end­ed up in the archives at Lin­coln Cen­ter, where it sat unno­ticed for decades, until Bec­ca Ben­der, an archivist, stum­bled up on it last year. And for­tu­nate­ly now we can all enjoy that light moment shot so long ago.

In years past, we let you know that Cal­tech and The Feyn­man Lec­tures Web­site joined forces to cre­ate an online edi­tion of The Feyn­man Lec­tures on Physics. They start­ed with Vol­ume 1. And they’ve since fol­lowed up with Vol­ume 2 and Vol­ume 3, mak­ing the col­lec­tion com­plete.

First pre­sent­ed in the ear­ly 1960s at Cal­tech by the Nobel Prize-win­ning physi­cist Richard Feyn­man, the lec­tures were even­tu­al­ly turned into a book by Feyn­man, Robert B. Leighton, and Matthew Sands. The text went on to become arguably the most pop­u­lar physics book ever writ­ten, sell­ing more than 1.5 mil­lion copies in Eng­lish, and get­ting trans­lat­ed into a dozen lan­guages.

The new online edi­tion makes The Feyn­man Lec­tures on Physics avail­able in HTML5. The text “has been designed for ease of read­ing on devices of any size or shape,” and you can zoom into text, fig­ures and equa­tions with­out degra­da­tion. Dive right into the lec­tures here. And if you’d pre­fer to see Feyn­man (as opposed to read Feyn­man), we would encour­age you to watch ‘The Char­ac­ter of Phys­i­cal Law,’ Feynman’s  sev­en-part lec­ture series record­ed at Cor­nell in 1964.

The Feyn­man Lec­tures on Physics is now list­ed in our col­lec­tions of Free eBooks and Free Text­books.

The Famous Schrodinger’s Cat Thought Experiment Comes Back to Life in an Off-Kilter Animation


Schrödinger’s Cat is one of the more famous thought exper­i­ments in mod­ern physics, cre­at­ed by Aus­tri­an physi­cist Erwin Schrödinger back in 1935.  The Tele­graph sum­ma­rizes the gist of the exper­i­ment as fol­lows:

In the hypo­thet­i­cal exper­i­ment … a cat is placed in a sealed box along with a radioac­tive sam­ple, a Geiger counter and a bot­tle of poi­son.

If the Geiger counter detects that the radioac­tive mate­r­i­al has decayed, it will trig­ger the smash­ing of the bot­tle of poi­son and the cat will be killed.

The exper­i­ment was designed to illus­trate the flaws of the ‘Copen­hagen inter­pre­ta­tion’ of quan­tum mechan­ics, which states that a par­ti­cle exists in all states at once until observed.

If the Copen­hagen inter­pre­ta­tion sug­gests the radioac­tive mate­r­i­al can have simul­ta­ne­ous­ly decayed and not decayed in the sealed envi­ron­ment, then it fol­lows the cat too is both alive and dead until the box is opened.

The Uni­ver­si­ty of Not­ting­ham’s Six­ty Sym­bols YouTube chan­nel pro­vides a more com­plete expla­na­tion. But with or with­out any fur­ther intro­duc­tion, you can watch the off-kil­ter ani­ma­tion, above, which imag­ines the ori­gins of the orig­i­nal exper­i­ment. It was cre­at­ed by Chav­dar Yor­danov for an ani­ma­tion show in Lon­don.
