Why Masks Work: A Slow Motion Demonstration (Plus a Guest Appearance by Dr. Fauci)

The Slo Mo Guys spe­cial­ize in tak­ing every­day occur­rences and slow­ing them down … way down, so that we can see them in a new way. In this clip, they let you see what hap­pens when you talk with­out a mask, and then with a mask–all in order to demon­strate why a mask helps pre­vent the trans­mis­sion of COVID-19, a dis­ease that’s main­ly spread when peo­ple are exposed to res­pi­ra­to­ry droplets car­ry­ing infec­tious virus. Around the 4 minute mark, the host is joined by Dr. Antho­ny Fau­ci, who offers com­men­tary on the footage.

The Gruesome Dollhouse Death Scenes That Reinvented Murder Investigations

Who can resist minia­tures?

Wee food, painstak­ing­ly ren­dered in felt­ed wool

Match­book-sized books you can actu­al­ly read…

Clas­sic record albums shrunk down for mice…

The late Frances Gless­ner Lee (1878–1962) def­i­nite­ly loved minia­tures, and excelled at their cre­ation, knit­ting socks on pins, hand rolling real tobac­co into tiny cig­a­rettes, and mak­ing sure the vic­tims in her real­is­tic mur­der scene dio­ra­mas exhib­it­ed the prop­er degree of rig­or mor­tis and livid­i­ty.

Lee began work on her Nut­shell Stud­ies of Unex­plained Death at the age of 65, as part of a life­long inter­est in homi­cide inves­ti­ga­tion.

Her pre­oc­cu­pa­tion began with the Sher­lock Holmes sto­ries she read as a girl.

In the 1930s, the wealthy divorcee used part of a siz­able inher­i­tance to endow Har­vard Uni­ver­si­ty with enough mon­ey for the cre­ation of its Depart­ment of Legal Med­i­cine.

Its first chair­man was her friend, George Burgess Magrath, a med­ical exam­in­er who had shared his dis­tress that crim­i­nals were lit­er­al­ly get­ting away with mur­der because coro­ners and police inves­ti­ga­tors lacked appro­pri­ate train­ing for foren­sic analy­sis.

The library to which Lee donat­ed a thou­sand books on the top­ic was named in his hon­or.

The home­made dio­ra­mas offered a more vivid expe­ri­ence than could be found in any book.

Each Nut­shell Study required almost half a year’s work, and cost about the same as a house would have at the time. ($6000 in the 1940s.)

“Luck­i­ly, I was born with a sil­ver spoon in my mouth,” Lee remarked. “It gives me the time and mon­ey to fol­low my hob­by of sci­en­tif­ic crime detec­tion.”

Although Lee had been brought up in a lux­u­ri­ous 13 bed­room home (8 were for ser­vants’ use), the domes­tic set­tings of the Nut­shell Stud­ies are more mod­est, reflec­tive of the vic­tims’ cir­cum­stances.

She drew inspi­ra­tion from actu­al crimes, but had no inter­est in repli­cat­ing their actu­al scenes. The crimes she authored for her lit­tle rooms were com­pos­ites of the ones she had stud­ied, with invent­ed vic­tims and in rooms dec­o­rat­ed accord­ing to her imag­i­na­tion.

Her intent was to pro­vide inves­ti­ga­tors with vir­gin crime scenes to metic­u­lous­ly exam­ine, culling indi­rect evi­dence from the painstak­ing­ly detailed props she was a stick­ler for get­ting right.

Stu­dents were pro­vid­ed with a flash­light, a mag­ni­fy­ing glass, and wit­ness state­ments. Her atten­tion to detail ensured that they would use the full nine­ty min­utes they had been allot­ted ana­lyz­ing the scene. Their goal was not to crack the case but to care­ful­ly doc­u­ment obser­va­tions on which a case could be built.

The flaw­less­ness of her 1:12 scale ren­der­ings also speaks to her deter­mi­na­tion to be tak­en seri­ous­ly in what was then an exclu­sive­ly male world. (Women now dom­i­nate the field of foren­sic sci­ence.)

Noth­ing was over­looked.

As she wrote to Dr. Alan Moritz, the Depart­ment of Legal Medicine’s sec­ond chair, in a let­ter review­ing pro­posed changes to some ear­ly scenes:

I found myself con­stant­ly tempt­ed to add more clues and details and am afraid I may get them “gad­gety” in the process. I hope you will watch over this and stop me when I go too far. Since you and I have per­pe­trat­ed these crimes our­selves we are in the unique posi­tion of being able to give com­plete descrip­tions of them even if there were no witnesses—very much in the man­ner of the nov­el­ist who is able to tell the inmost thoughts of his char­ac­ters.

It’s no acci­dent that many of the Nut­shell Stud­ies’ lit­tle corpses are female.

Lee did not want offi­cers to treat vic­tims dis­mis­sive­ly because of gen­der-relat­ed assump­tions, whether the sce­nario involved a pros­ti­tute whose throat has been cut, or a house­wife dead on the floor of her kitchen, the burn­ers of her stove all switched to the on posi­tion.

Would you like to test your pow­ers of obser­va­tion?

Above are the remains of Mag­gie Wil­son, dis­cov­ered in the Dark Bath­room’s tub by a fel­low board­er, Lizzie Miller, who gave the fol­low­ing state­ment:

I roomed in the same house as Mag­gie Wil­son, but knew her only from we met in the hall. I think she had ‘fits’ [seizures]. A cou­ple of male friends came to see her fair­ly reg­u­lar­ly. On Sun­day night, the men were there and there was a lot of drink­ing going on. Some time after the men left, I heard the water run­ning in the bath­room. I opened the door and found her as you see her.

Grim, eh?

Not near­ly as grim as what you’ll find in the Par­son­age or the Three-Room Dwelling belong­ing to shoe fac­to­ry fore­man Robert Jud­son, his wife, Kate, and their baby, Lin­da Mae.

The peri­od-accu­rate mini fur­nish­ings and fash­ions may cre­ate a false impres­sion that the Moth­er of Foren­sic Sci­ence’s Nut­shell Stud­ies should be rel­e­gat­ed to a muse­um.

In truth, their abun­dance of detail remains so effec­tive that the Office of the Chief Med­ical Exam­in­er in Bal­ti­more con­tin­ues to use 18 of them in train­ing sem­i­nars to help homi­cide inves­ti­ga­tors “con­vict the guilty, clear the inno­cent, and find the truth in a nut­shell.”

Watch a Young Carl Sagan Appear in His First TV Documentary, The Violent Universe (1969)

Much of the world got to know Carl Sagan through Cos­mos: A Per­son­al Voy­age, the thir­teen-part PBS series on the nature of the uni­verse — and the inten­si­ty of Sagan’s own pas­sion to dis­cov­er that nature. First aired in 1980, it would become the most wide­ly watched series in the his­to­ry of Amer­i­can pub­lic tele­vi­sion. But it’s not as if Sagan had been lan­guish­ing in obscu­ri­ty before: he’d been pub­lish­ing pop­u­lar books since the ear­ly 1970s, and 1977’s The Drag­ons of Eden: Spec­u­la­tions on the Evo­lu­tion of Human Intel­li­gence won him a Pulitzer Prize. When Cos­mos made its impact, some view­ers may even have remem­bered its host from a series of sim­i­lar­ly themed broad­casts a decade ear­li­er, The Vio­lent Uni­verse.

Pro­duced by the BBC in 1969 and broad­cast just three months before the Apol­lo 11 moon land­ingThe Vio­lent Uni­verse (view­able above) explains in five parts a range of dis­cov­er­ies made dur­ing the then-recent “rev­o­lu­tion in astron­o­my,” includ­ing infrared galax­ies, neu­tri­nos, pul­sars and quasars, red giants and white dwarfs.

In so doing it includes footage tak­en in obser­va­to­ries not just across the Earth — Eng­land, Puer­to Rico, Hol­land, Cal­i­for­na — but high above it in orbit and even deep inside it, beneath the bad­lands of South Dako­ta. One install­ment pays a vis­it to Kōchi, the rur­al Japan­ese pre­fec­tur­al cap­i­tal where gui­tarist-astronomer Tsu­to­mu Seki makes his home — and his small home obser­va­to­ry, where he had worked to co-dis­cov­er Comet Ikeya–Seki just four years before.

All of this inter­na­tion­al mate­r­i­al — or rather inter­stel­lar mate­r­i­al — is anchored in the stu­dio by tele­vi­sion jour­nal­ist Robert Mac­Neil, lat­er of PBS’ The MacNeil/Lehrer Report, and a cer­tain pro­fes­sor of astron­o­my at Cor­nell Uni­ver­si­ty by the name of Carl Sagan. Despite exud­ing a more delib­er­ate seri­ous­ness than he would in Cos­mos, the young Sagan nev­er­the­less explains the astro­nom­i­cal and astro­phys­i­cal con­cepts at hand with a clar­i­ty and vig­or that would have made them imme­di­ate­ly clear to tele­vi­sion audi­ences of half a cen­tu­ry ago, and indeed still makes them clear to the Youtube audi­ences of today. Apart, per­haps, from its Twi­light Zone-style theme music The Vio­lent Uni­verse has in its visu­al ele­ments aged more grace­ful­ly than the 70s series that made Sagan into a sci­ence icon. And how many oth­er oth­er pub­lic-tele­vi­sion doc­u­men­taries about the uni­verse include poet­ry recita­tions from Richard Bur­ton?

GPS Tracking Reveals the Secret Lives of Outdoor Cats

We track sharksrhi­no, and bears, so why not Boo Boo Kit­tyPeanut, and Pump­kin?

The Long Island feline res­i­dents volunteered—or more accu­rate­ly, were volunteered—by their human com­pan­ions to par­tic­i­pate in a domes­tic cat move­ment study as part of the inter­na­tion­al Cat Track­er project.

Each beast was out­fit­ted with a GPS track­er-enhanced har­ness, which they wore for a week.

(Many cat own­ers will find that alone some­thing of an achieve­ment.)

In total, almost a thou­sand house­holds in four coun­tries took part—the Unit­ed StatesNew ZealandAus­tralia, and the UK.

Sci­en­tists were par­tic­u­lar­ly inter­est­ed to learn the degree of may­hem these cher­ished pets were vis­it­ing on sur­round­ing wildlife in their off hours.

Any­one who’s been left a present of a fresh­ly mur­dered baby bun­ny, mole, or wing­less bat can prob­a­bly guess.

It’s a con­sid­er­able amount, though by and large the domes­ti­cat­ed par­tic­i­pants stuck close to home, rarely trav­el­ing more than two foot­ball fields away from the com­forts of their own yards. The impulse to keep the food bowl with­in easy range con­fines their hunt­ing activ­i­ties to a fair­ly tight area. Woe to the field mice who set up shop there.

Their move­ments also revealed the per­il they put them­selves in, cross­ing high­ways, roads, and park­ing lots. Researcher Hei­dy Kikil­lus, who tracked cats in New Zealand, report­ed that a num­ber of her group’s sub­jects wound up in a fatal encounter with a vehi­cle.

Gen­er­al­ly speak­ing, gen­der, age, and geog­ra­phy play a part in how far a cat roams, with males, younger ani­mals, and coun­try dwellers cov­er­ing more ground. Unsur­pris­ing­ly, those who have not been neutered or spayed tend to have a freer range too.

“With­out the moti­va­tions of food and sex, most cats seem con­tent to be home­bod­ies,” zool­o­gist Roland Kays, one of the US Project lead­ers, not­ed.

Amer­i­can cit­i­zen sci­en­tists who’d like to enroll their cat can find infor­ma­tion and the nec­es­sary forms on the Cat Track­er web­site.

The cat-less and those with indoor cats can enjoy pho­tos of select par­tic­i­pants and explore their tracks here.

And what bet­ter fall craft than a DIY cat track­ing GPS har­ness?

Hear Readings of Albert Einstein’s Love Letters (and Chilly Divorce Letters) to His First Wife Mileva

Beware the fake quo­ta­tion. They have become so ubiq­ui­tous they often appear in books and speech­es by politi­cians and their fam­i­ly mem­bers, not that any­one seems to care much. But most of us feel a mea­sure of shame at being duped, as Katharine Rose did when she found her­self moved by a let­ter sup­pos­ed­ly writ­ten by Albert Ein­stein to his daugh­ter, Lieserl, “regard­ing the ‘uni­ver­sal force’ of love.” The let­ter is a “beau­ti­ful read,” and it’s a fake. But many admir­ers of Ein­stein were eager to believe it.

Why? Like oth­er famous fig­ures to whom spu­ri­ous words are attrib­uted, Ein­stein isn’t just well-known, he is revered, a celebri­ty, and celebri­ties are peo­ple we feel we know inti­mate­ly. (A com­mon defense for fake-quote-shar­ing goes: “Well, if he didn’t say it, then it’s exact­ly the kind of thing he would say.”) Dis­cussing the theft of Einstein’s brain after his death, Ross Ander­son at Aeon observes that “an ordi­nary per­son can live and die pri­vate­ly, but a genius—and his grey matter—belongs to the world.” We might add, “and so do the inti­mate details of his pri­vate life.”

The details of Einstein’s mar­riage, and of his very unpleas­ant sep­a­ra­tion and divorce, from Mil­e­va Mar­ić have long been pub­lic knowl­edge. “Few pub­lic mar­riages have been sub­ject­ed to a more unnu­anced ver­dict,” Maria Popo­va writes at Brain Pick­ings. Their love let­ters first came to light in 1986, dis­cov­ered by Einstein’s grand­daugh­ter Eve­lyn. They were pub­lished in 1992 as The Love Let­ters, “a col­lec­tion of fifty-four mis­sives exchanged between the begin­ning of their romance” when they met as stu­dents in 1897 to their mar­riage in 1903. Dozens more are avail­able at Prince­ton Uni­ver­si­ty’s online col­lec­tion of Ein­stein’s papers.

The let­ters are real, and they are “spicy,” as YouTu­ber Tibees shows us in the video at the top. No awk­ward pri­vate expres­sion is safe: we begin with let­ters Ein­stein wrote to his high school girl­friend, Marie Win­tel­er, includ­ing a breakup let­ter at 3:13. The excerpts here are all time­stamped on the video’s YouTube page, with help­ful sum­maries like “Einstein’s mom try­ing to break them up” (them being Albert and Mil­e­va), “Ein­stein hav­ing an affair with his cousin Elsa,” “Break­ing up with Elsa,” and “Get­ting back with Elsa.”

Elsa, you may know, was Einstein’s sec­ond wife, in addi­tion to being his cousin, and the cause of his sep­a­ra­tion and divorce from Mil­e­va, to whom he had pro­fessed undy­ing devo­tion. In the inter­est of ful­ly invad­ing the genius’s pri­va­cy, we have, above, some read­ings of his harsh “divorce let­ters” to Mil­e­va, with hits like “Sep­a­ra­tion,” “Propos­ing divorce,” and “Court pro­ceed­ings.” Love may or may not be a “uni­ver­sal force”—we do not, sad­ly, have Einstein’s thoughts on the matter—but we do know he found it a trou­bling­ly chaot­ic, unpre­dictable one.

Explore Dozens of Drawings by Charles Darwin’s Creative Children

Charles Dar­win’s work on hered­i­ty was part­ly dri­ven by trag­ic loss­es in his own fam­i­ly. Dar­win had mar­ried his first cousin, Emma, and “won­dered if his close genet­ic rela­tion to his wife had had an ill impact on his children’s health, three (of 10) of whom died before the age of 11,” Kather­ine Har­mon writes at Sci­en­tif­ic Amer­i­can. (His sus­pi­cions, researchers sur­mise, may have been cor­rect.) He was so con­cerned about the issue that in 1870, he pres­sured the gov­ern­ment to include ques­tions about inbreed­ing on the cen­sus (they refused).

Darwin’s chil­dren would serve as sub­jects of sci­en­tif­ic obser­va­tion. His note­books, says Ali­son Pearn of the Dar­win Cor­re­spon­dence Project at Cam­bridge Uni­ver­si­ty Library, show a curi­ous father “prod­ding and pok­ing his young infant,” Charles Eras­mus, his first child, “like he’s anoth­er ape.” Com­par­isons of his children’s devel­op­ment with that of orang­utans helped him refine ideas in On the Ori­gin of Species, which he com­plet­ed as he raised his fam­i­ly at their house in rur­al Kent, and inspired lat­er ideas in Descent of Man.

But as they grew, the Dar­win chil­dren became far more than sci­en­tif­ic curiosi­ties. They became their father’s assis­tants and appren­tices. “It’s real­ly an envi­able fam­i­ly life,” Pearn tells the BBC. “The sci­ence was every­where. Dar­win just used any­thing that came to hand, all the way from his chil­dren right through to any­thing in his house­hold, the plants in the kitchen gar­den.” Steeped in sci­en­tif­ic inves­ti­ga­tion from birth, it’s lit­tle won­der so many of the Dar­wins became accom­plished sci­en­tists them­selves.

Down House was “by all accounts a bois­ter­ous place,” writes McKen­na Staynor at The New York­er, “with a wood­en slide on the stairs and a rope swing on the first-floor land­ing.” Anoth­er archive of Darwin’s prodi­gious writ­ing, Cambridge’s Dar­win Manuscript’s Project, gives us even more insight into his fam­i­ly life, with graph­ic evi­dence of the Dar­win brood’s curios­i­ty in the dozens of doo­dles and draw­ings they made in their father’s note­books, includ­ing the orig­i­nal man­u­script copy of his mag­num opus.

The project’s direc­tor David Kohn “doesn’t know for cer­tain which kids were the artists,” notes Staynor, “but he guess­es that at least three were involved: Fran­cis, who became a botanist; George, who became an astronomer and math­e­mati­cian; and Horace, who became an engi­neer.” One imag­ines com­pe­ti­tion among the Dar­win chil­dren must have been fierce, but the draw­ings, “though exact­ing, are also play­ful.” One depicts “The Bat­tle of Fruits and Veg­eta­bles.” Oth­ers show anthro­po­mor­phic ani­mals and illus­trate mil­i­tary fig­ures.

There are short sto­ries, like “The Fairies of the Moun­tain,” which “tells the tale of Poly­tax and Short Shanks, whose wings have been cut off by a ‘naughty fairy.’” Imag­i­na­tion and cre­ativ­i­ty clear­ly had a place in the Dar­win home. The man him­self, Maria Popo­va notes, felt sig­nif­i­cant ambiva­lence about father­hood. “Chil­dren are one’s great­est hap­pi­ness,” he once wrote, “but often & often a still greater mis­ery. A man of sci­ence ought to have none.”

It was an atti­tude born of grief, but one, it seems, that did not breed aloof­ness. The Dar­win kids “were used as vol­un­teers,” says Kohn, “to col­lect but­ter­flies, insects, and moths, and to make obser­va­tions on plants in the fields around town.” Fran­cis fol­lowed his father’s path and was the only Dar­win to co-author a book with his father. Darwin’s daugh­ter Hen­ri­et­ta became his edi­tor, and he relied on her, he wrote, for “deep crit­i­cism” and “cor­rec­tions of style.”

Despite his ear­ly fears for their genet­ic fit­ness, Darwin’s pro­fes­sion­al life became inti­mate­ly bound to the suc­cess­es of his chil­dren. The Dar­win Man­u­scripts Project, which aims to dig­i­tize and make pub­lic around 90,000 pages from the Cam­bridge Uni­ver­si­ty Library’s Dar­win col­lec­tion, will have a pro­found effect on how his­to­ri­ans of sci­ence under­stand his impact. “The scope of the enter­prise, of what we call evo­lu­tion­ary biol­o­gy,” says Kohn, “is defined in these papers. He’s got his foot in the twen­ti­eth cen­tu­ry.”

The archive also shows the devel­op­ment of Darwin’s equal­ly impor­tant lega­cy as a par­ent who inspired a bound­less sci­en­tif­ic curios­i­ty in his kids. See many more of the dig­i­tized Dar­win children’s draw­ings at Brain Pick­ings.

What Made Richard Feynman One of the Most Admired Educators in the World

If Richard Feyn­man had only ever pub­lished his work in the­o­ret­i­cal physics, his name would still be known far and wide. As it is, Feyn­man remains famous more than thir­ty years after his death in large part for the way he engaged with the pub­lic. From his pop­u­lar text­book The Feyn­man Lec­tures on Physics (which you can read free online here) to his best­selling con­ver­sa­tion­al essay col­lec­tions like Sure­ly You’re Jok­ing, Mr. Feyn­man to the class­es he taught at Cor­nell (now avail­able online) to his demon­stra­tion of what went wrong with the Space Shut­tle Chal­lenger, he kept in con­ver­sa­tion all his life with human­i­ty out­side the realm of pro­fes­sion­al sci­ence. This explains, in part, why Feyn­man became what Bill Gates calls, in the video above, “the best teacher I nev­er had.”

Gates points to Feyn­man’s lec­ture series “The Char­ac­ter of Phys­i­cal Law,” pre­vi­ous­ly fea­tured here on Open Cul­ture, as “a great exam­ple of how he could explain things in a fun and inter­est­ing way to every­one. And he was very fun­ny.”

That sense of humor com­ple­ment­ed a sense of rig­or: “Dr. Feyn­man used a tough process on him­self, where if he did­n’t real­ly under­stand some­thing, he would push him­self,” ask­ing ques­tions like “Do I under­stand this bound­ary case?” and “Do I under­stand why we don’t do it this oth­er way?” Such an effort to find the gaps in and fail­ures of one’s own under­stand­ing may sound famil­iar, fun­da­men­tal as it is to Feyn­man’s “note­book” tech­nique of learn­ing that we’ve post­ed about more than once before.

You only know how well you under­stand some­thing when you explain it to some­one else; many of us real­ize this, but Feyn­man lived it. The depth of his own under­stand­ing allowed him nev­er to be bor­ing: “Feyn­man made sci­ence so fas­ci­nat­ing,” Gates says, “He remind­ed us how much fun it is,” and in so doing empha­sized that “every­body can have a pret­ty full under­stand­ing. He’s such a joy­ful exam­ple of how we’d all like to learn and think about things.” Though the term “sci­ence com­mu­ni­ca­tor” was­n’t in wide use dur­ing Feyn­man’s life­time, he played the role to near-per­fec­tion. And in the kind of mate­ri­als high­light­ed here, he con­tin­ues to con­vey not just knowl­edge but, as he liked to put it, the plea­sure of find­ing things out.

What if I said the prob­lem with STEM edu­ca­tion is that it doesn’t include near­ly enough art? For one thing, I would only echo what STEAM pro­po­nents have said for years. This does­n’t only mean that stu­dents should study the arts with the same seri­ous­ness as they do the sci­ences. But that sci­ence should be taught through the arts, as it was in the 19th cen­tu­ry when Nat­u­ral­ists relied on fine art illus­tra­tion.

Maybe increas­ing com­plex­i­ty demands charts and graphs, but there are rea­sons oth­er than hip anti­quar­i­an­ism to cher­ish 19th cen­tu­ry sci­en­tif­ic art, and to aim for some­thing close to its high aes­thet­ic stan­dards. Humans seem to find nature far more awe-inspir­ing when it’s medi­at­ed by paint­ing, poet­ry, nar­ra­tive, music, fine art pho­tog­ra­phy, etc. We want to be emo­tion­al­ly moved by sci­ence. As such, few guides to the nat­ur­al world have ele­vat­ed their sub­jects as high­ly as British & Exot­ic Min­er­al­o­gy, a mul­ti­vol­ume ref­er­ence work for… well, rocks, to put it vul­gar­ly, pub­lished between 1802 and 1817.

Dur­ing these years, “notable nat­u­ral­ist, illus­tra­tor, and min­er­al­o­gist James Sower­by drew intri­cate pic­tures of min­er­als in an effort to illus­trate the topo­graph­ic min­er­al­o­gy of Great Britain and min­er­als not yet known to it,” writes Nicholas Rougeux. “These illus­tra­tions were some of the finest on the sub­ject and are still con­sid­ered by some to be to this day.” Though he was sure­ly com­pen­sat­ed for his work, Sowerby’s detailed draw­ings come across as labors of devo­tion.

Rather than just print­ing them on post­cards or tote bags (though he does sell posters), Rougeux has done for Sowerby’s min­er­als what he had pre­vi­ous­ly done for oth­er clas­sic text­books and tax­onomies from the past, such as the 200-year-old Werner’s Nomen­cla­ture of Colours and Euclid’s Ele­ments from 1847. Dig­i­tiz­ing the 718 illus­tra­tions on one sprawl­ing inter­ac­tive page allows him to retain their edu­ca­tion­al val­ue: click on any indi­vid­ual min­er­al and you’ll bring up an enlarged image fol­lowed by excerpts from the text.

You have nev­er seen such rocks as these, no mat­ter how many uncut gems you’ve held in your hand. Because these illus­tra­tions turn them into some­thing else—crystalline palaces, alien organs, pet­ri­fied explo­sions, moldy loaves of bread… all the many shapes that time can take in rock form. They aren’t all beau­ti­ful rocks, but they are each beau­ti­ful­ly-ren­dered with lines that might remind us of the most skilled com­ic artists, who are per­haps some of the last inher­i­tors of this kind of graph­ic style. Sower­by him­self illus­trat­ed sev­er­al oth­er sci­en­tif­ic works, includ­ing series on biol­o­gy, mycol­o­gy, and a col­or sys­tem of his own devis­ing.

“We feel much plea­sure in pre­sent­ing our friends with a fig­ure and account of the most per­fect and rare spec­i­men yet found of this sub­stance,” begins the text accom­pa­ny­ing Hydrargillite, above, which resem­bles a small, mis­shapen moon or aster­oid. Rougeux also takes quite a bit of plea­sure in his work of recov­er­ing these ref­er­ence books and mak­ing them beau­ti­ful­ly use­ful once again for 21st cen­tu­ry read­ers. You can read his detailed account of the orig­i­nal illus­tra­tions and his adap­ta­tion of them for use on the web here.

While appre­ci­at­ing the fin­er points of col­or, line, and com­po­si­tion in Rougeux’s tapes­try of vin­tage min­er­al illus­tra­tions, you might just inad­ver­tent­ly expand your knowl­edge and appre­ci­a­tion of min­er­al­o­gy. You can also read the entire British & Exot­ic Min­er­al­o­gy, if you’ve got the time and incli­na­tion, at the Inter­net Archive.
