A Brilliant Demonstration of Magnets & the Promise of Levitating Trains (1975)

For a brief time in the 1980s, it seemed like trains pow­ered by maglev — mag­net­ic lev­i­ta­tion — might just solve trans­porta­tion prob­lems every­where, maybe even replac­ing air trav­el, there­by elim­i­nat­ing one of the most vex­ing sources of car­bon emis­sions. Maglev trains don’t use fuel; they don’t require very much pow­er by com­par­i­son with oth­er sources of high speed trav­el; they don’t pro­duce emis­sions; they’re qui­et, require less main­te­nance than oth­er trains, and can trav­el at speeds of 300 mph and more. In fact, the fastest maglev train to date, unveiled this past sum­mer in Qing­dao, Chi­na, can reach speeds of up to 373 miles per hour (600 kph).

So, why isn’t the plan­et criss-crossed by maglev trains? asks Dave Hall at The Guardian, cit­ing the fact that the first maglev train was launched in the UK in 1984, after which Ger­many, Japan, and Chi­na fol­lowed suit. It seems to come down, as such things do, to “polit­i­cal will.” With­out sig­nif­i­cant com­mit­ment from gov­ern­ments to reshape the trans­porta­tion infra­struc­ture of their coun­tries, maglev trains remain a dream, the mono­rails of the future that nev­er mate­ri­al­ize. Even in Chi­na, where gov­ern­ment man­date can insti­tute mass changes at will, the devel­op­ment of maglev trains has not meant their deploy­ment. The new train could, the­o­ret­i­cal­ly, fer­ry trav­el­ers between Shang­hai to Bei­jing in 2.5 hours… if it had the track.

Per­haps some­day the world will catch up with maglev trains, an idea over a cen­tu­ry old. (The first patents for maglev tech­nol­o­gy were filed by a French-born Amer­i­can engi­neer named Emile Bachelet in the 1910s.) Until then, the rest of us can edu­cate our­selves on the tech­nol­o­gy of trains that use mag­net­ic lev­i­ta­tion with the 1975 video les­son above from British engi­neer and pro­fes­sor Eric Laith­waite (Impe­r­i­al Col­lege Lon­don), who “decon­structs the fas­ci­nat­ing physics at work behind his plans for a maglev trains, which he first mod­elled in the 1940s and per­fect­ed in the 1970s,” notes Aeon. “Well-regard­ed in his time as both a lec­tur­er and an engi­neer, Laith­waite presents a series of demon­stra­tions that build, step by step, until he final­ly unveils a small maglev train mod­el.”

Laithwaite’s small-scale demon­stra­tion would even­tu­al­ly cul­mi­nate in the first com­mer­cial maglev train almost a decade lat­er at Birm­ing­ham Air­port. Here, he begins where sci­ence begins, with an admis­sion of igno­rance. “Per­ma­nent mag­nets are dif­fi­cult things to under­stand,” he says. “In fact, if we’re absolute­ly hon­est with our­selves, we don’t under­stand them.” The good pro­fes­sor then briskly moves on to demon­strate what he does know — enough to build a lev­i­tat­ing train. Learn much more about the his­to­ry and tech­nol­o­gy of maglev trains at How Stuff Works, and keep your eyes on the North­east Maglev project, a devel­op­ing Super­con­duct­ing Maglev train that promis­es trav­el between New York and Wash­ing­ton, DC in one hour flat.

Footage of the Last Known Tasmanian Tiger Restored in Color (1933)

Last month, the U.S. Fish and Wildlife Ser­vice announced that near­ly two dozen wildlife species would be removed from the endan­gered species list, as CNN report­ed, includ­ing the ivory-billed wood­peck­er, “the Bachman’s war­bler, two species of fresh­wa­ter fish­es, eight species of South­east­ern fresh­wa­ter mus­sels and 11 species from Hawaii and the Pacif­ic Islands.” This is not good news. The ani­mals have been delist­ed because they’ve been added to a list of extinct crea­tures, one that grows longer each year.

Most of us have seen few, if any, of these ani­mals and can­not grasp the scope of their loss. What does it mean to say there are no more Bachman’s war­blers left on Earth? Species wiped out by cli­mate change, over­farm­ing, over­fish­ing, or the encroach­ment of humans and inva­sive species can feel far away from us, their loss a dis­tant tragedy; or extinc­tion can seem inevitable, like that of the Dodo or Sicil­ian wolf, crea­tures that seem too fan­tas­tic for the world we now inhab­it. So too, the dog-like mar­su­pi­al Tas­man­ian tiger — or thy­lacine — an ani­mal that lived as recent­ly as 1936 when the last rep­re­sen­ta­tive of its species, named Ben­jamin, died in cap­tiv­i­ty in Aus­tralia.

The thy­lacine looks like an evo­lu­tion­ary odd­i­ty, too weird to sur­vive. But this judg­ment is a mis­ap­pli­ca­tion of Dar­win­ism as egre­gious as the idea that only the “fittest,” i.e. those who can take good beat­ing, sur­vive. The day Ben­jamin died, Sep­tem­ber 7, has been com­mem­o­rat­ed in Aus­tralia as Nation­al Threat­ened Species Day, which rais­es aware­ness about the hun­dreds of plant and ani­mal species close to extinc­tion. The day also cel­e­brates the hun­dreds of species found nowhere else in the world, ani­mals that could come to seem to us in the near future as strange and exot­ic as the thy­lacine — a fas­ci­nat­ing exam­ple of con­ver­gent evo­lu­tion: a mar­su­pi­al canid that evolved com­plete­ly inde­pen­dent­ly of wolves, dogs, and oth­er canine species with which it had no con­tact what­so­ev­er until the British arrived.

Found only on the island of Tas­ma­nia by the time of Euro­pean set­tle­ment, thy­lacine pop­u­la­tions were destroyed by dis­ease, dogs, and, pri­mar­i­ly, human hunters. Before the final mem­ber of the species died, they were kept in zoos and cap­tured on silent film by nat­u­ral­ists like David Fleay, who shot the black-and-white footage just above of Ben­jamin at Beau­maris Zoo in Hobart, Tas­ma­nia. In the video at the top, we can see the same footage in vivid col­or — and full dig­i­tal restora­tion — thanks to Samuel François-Steininger and his Paris-based com­pa­ny Com­pos­ite Films.

Sent an HDR (High Dynam­ic Range) scan of the film by the Nation­al Film and Sound Archive of Aus­tralia (NFSA), François-Steininger had to make a lot of inter­pre­tive choic­es. Next to “orig­i­nal skins pre­served in muse­ums,” the NFSA notes, his team “had to rely on sketch­es and paint­ings because of the lack of orig­i­nal col­or pic­tures or footage that could be used for research.” While there are 9 short film clips of the ani­mals from the Lon­don and Hobart zoos, these are all, of course, in black and white. “Writ­ten descrip­tions of the thy­lacine’s coat gave them a gen­er­al idea of the tints and shades present in the fur, infor­ma­tion they sup­ple­ment­ed with sci­en­tif­ic draw­ings and recent 3D col­or ren­der­ings of the ani­mal.” The results are incred­i­bly nat­ur­al-look­ing and star­tling­ly imme­di­ate.

Are the thy­lacine, Bach­man’s war­bler, and oth­er extinct species vic­tims of the Anthro­pocene? Will our chil­dren’s chil­dren chil­dren watch films of polar bears and koalas and won­der how our plan­et could have con­tained such won­ders? Geo­log­i­cal epochs deal with “mile-thick pack­ages of rock stacked up over tens of mil­lions of years,” Peter Bran­nen writes at The Atlantic, and thus it over­states the case to call the last four cen­turies of cli­mate change and mass extinc­tion an “Anthro­pocene.” The word names “a thought exper­i­ment” rather than a span of deep time in Earth’s his­to­ry. But from the per­spec­tive of crit­i­cal­ly endan­gered species — maybe to include, even­tu­al­ly, humans them­selves — the trans­for­ma­tions of the present seem square­ly focused on our reck­less behav­ior and its effects on habi­tats we nev­er see.

We are far less impor­tant to geo­log­i­cal time than we think, Bran­nen argues, but it does, indeed, seem up to us at the moment whether there is a future on Earth filled with plant, ani­mal, and yes, human, life:

We haven’t earned an Anthro­pocene epoch yet. If some­day in the dis­tant future we have, it will be an astound­ing tes­ta­ment to a species that, after a col­icky, globe-threat­en­ing infan­cy, learned that it was not sep­a­rate from Earth his­to­ry, but a con­tigu­ous part of the sys­tems that have kept this mirac­u­lous mar­ble world hab­it­able for bil­lions of years.

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.

How Mushroom Time-Lapses Are Filmed: A Glimpse Into the Pioneering Time-Lapse Cinematography Behind the Netflix Documentary Fantastic Fungi

Mush­rooms are hav­ing a moment, thanks in part to pio­neer­ing time-lapse cin­e­matog­ra­ph­er Louie Schwartzberg’s doc­u­men­tary Fan­tas­tic Fun­gi.

Now stream­ing on Net­flix, the film has giv­en rise to a bumper crop of funghi fantat­ics, who sprang up like, well, mush­rooms, to join the exist­ing ranks of cit­i­zen sci­en­tistsculi­nary fansweek­end for­agersama­teur grow­ers, and spir­i­tu­al seek­ers.

Schwartzberg, who ear­li­er visu­al­ized pol­li­na­tion from the flower’s point of view in the Meryl Streep-nar­rat­ed Wings of Life, is a true believ­er in the pow­er of mush­rooms, cit­ing funghi’s role in soil cre­ation and health, and their poten­tial for rem­e­dy­ing a num­ber of press­ing glob­al prob­lems, as well as a host of human ail­ments.

Fan­tas­tic Funghi focus­es on sev­en pil­lars of ben­e­fits brought to the table by the fun­gal king­dom and its Inter­net-like under­ground net­work of myceli­um:

  1. Bio­di­ver­si­ty

A num­ber of projects are explor­ing the ways in which the myceli­um world can pull us back from the bring of  deser­ti­za­tion, water short­age, food short­age, bee colony col­lapsetox­ic con­t­a­m­i­nants, nuclear dis­as­ters, oil spills, plas­tic pol­lu­tion, and glob­al warm­ing.

  1. Inno­va­tion

Mush­room-relat­ed indus­tries are eager to press funghi into ser­vice as envi­ron­men­tal­ly sus­tain­able faux leatherbuild­ing mate­ri­als, pack­ag­ing, and meat alter­na­tives.

  1. Food

From fine din­ing to for­ag­ing off-the-grid, mush­rooms are prized for their culi­nary and nutri­tion­al ben­e­fits.

  1. Phys­i­cal Health and Well­ness

Will the hum­ble mush­room prove mighty enough to do an end run around pow­er­ful drug com­pa­nies as a source of inte­gra­tive med­i­cine to help com­bat dia­betes, liv­er dis­ease, inflam­ma­tion, insom­nia and cog­ni­tive decline?

  1. Men­tal Health

Researchers at Johns Hop­kinsUCLA, and NYU are run­ning clin­i­cal tri­als on the ben­e­fits of psy­che­del­ic psilo­cy­bin mush­rooms as a tool for treat­ing addic­tion, depres­sion, anx­i­ety, PTSD and sui­ci­dal ideation.

  1. Spir­i­tu­al­i­ty

Of course, there’s also a rich tra­di­tion of reli­gions and indi­vid­ual seek­ers deploy­ing mind alter­ing psy­choac­tive mush­rooms as a form of sacra­ment or a tool for plumb­ing the mys­ter­ies of life.

  1. The Arts

Direc­tor Schwartzberg under­stand­ably views mush­rooms as muse, a fit­ting sub­ject for pho­tog­ra­phy, music, film, poet­ry, art and oth­er cre­ative endeav­ors.

 

With regard to this final pil­lar, many view­ers may be sur­prised to learn how much of the 15 years Schwartzberg ded­i­cat­ed to cap­tur­ing the exquis­ite cycle of fun­gal regen­er­a­tion and decom­po­si­tion took place indoors.

As he explains in the Wired video above, his pre­ci­sion equip­ment excels at cap­tur­ing devel­op­ment that’s invis­i­ble to the human eye, but is no match for such nat­ur­al world dis­rup­tions as insects and wind.

Instead, he and his team built con­trolled grow­ing envi­ron­ments, where high­ly sen­si­tive time lapse cam­eras, dol­lies, timed grow lights, and more cin­e­mat­ic light­ing instru­ments could be left in place.

Set dress­ings of moss and logs, cou­pled with a very short depth of field helped to bring the Great Out­doors onscreen, with occa­sion­al chro­makeyed panora­mas of the nat­ur­al world fill­ing in the gaps.

Even in such lab-like con­di­tions, cer­tain ele­ments were nec­es­sar­i­ly left to chance. Mush­rooms grow noto­ri­ous­ly quick­ly, and even with con­stant mon­i­tor­ing and cal­cu­la­tions, there was plen­ty of poten­tial for one of his stars to miss their mark, shoot­ing out of frame.

Just one of the ways that mush­rooms and humans oper­ate on rad­i­cal­ly dif­fer­ent time­lines. The direc­tor bowed to the shrooms, return­ing to square one on the fre­quent occa­sions when a sequence got away from him.

Pro­vid­ing view­ers an immer­sive expe­ri­ence of the under­ground myceli­um net­work required high pow­ered micro­scopes, a sol­id cement floor, and a bit of movie mag­ic to finesse. What you see in the final cut is the work of CGI ani­ma­tors, who used Schwartzberg’s footage as their blue­print.

The Brilliant 19th-Century Astronomical Drawings of Étienne Léopold Trouvelot


The first pho­to of the moon was tak­en in 1850 by Louis Daguerre, from whom the daguer­rotype gets its name. We have no idea what that first image looked like as it was lost in a stu­dio fire. But the need to cat­a­log the heav­ens with mod­ern tools had start­ed, and was both fas­ci­nat­ing as it was lack­ing. Into this evo­lu­tion of sci­ence and art stepped Éti­enne Léopold Trou­velot, the French immi­grant, liv­ing in the States, an ama­teur sci­en­tist and an illus­tra­tor. He would dis­miss pho­tog­ra­phy of the heav­ens as “so blurred and indis­tinct that no details of any great val­ue can be secured.” And by illus­trat­ing instead by he saw through tele­scopes, he secured a place in art *and* sci­ence his­to­ry.

Trou­velot might have thought his sci­en­tif­ic papers would be his lega­cy. He wrote fifty in his life­time. Instead it is his rough­ly 7,000 illus­tra­tions of plan­ets, comets, and oth­er phe­nom­e­na that still please us to this day. The New York Pub­lic Library has put 15 of his best up on their site, and over at this page, you can com­pare what Trou­velot saw—-the great astronomer Emma Con­verse called Trou­velot the “prince of observers”—-to pho­tos from NASA’s archive.

Even if his Mars is a bit fan­ci­ful, look­ing translu­cent like a fish egg, his under­stand­ing of the plan­et echoes in the fol­low­ing cen­tu­ry of sci-fi para­noia. Some­thing strange must be there, he sug­gests.

Har­vard hired him to sketch at their college’s obser­va­to­ry, and he used pas­tels to bring the plan­ets to life. Engrav­ing or ink would not have worked as well as these soft shapes and deter­mined lines. His ren­der­ing of the moon sur­face is accu­rate but also fan­ci­ful, like whipped cream. And his sun spots might not be accu­rate, but they repli­cat­ed the god-like forces at work on its tumul­tuous sur­face. His Sat­urn is the most real­is­tic of them all. Even the NASA image doesn’t look too dif­fer­ent to Trouvelot’s art.

These images also help reha­bil­i­tate Trouvelot’s oth­er legacy—-the dread­ed Gyp­sy Moth. Before his stint as ama­teur sci­en­tist, he was also an ama­teur ento­mol­o­gist, and while research­ing silk­worms and silk pro­duc­tion, acci­den­tal­ly let Euro­pean gyp­sy moths into North Amer­i­ca, where they wreaked hav­oc on the forests of North Amer­i­ca. Saturn’s rings may look the same back then as they do now, but so does the dam­age of the gyp­sy moth, which accord­ing to Wikipedia is up to $868 mil­lion in dam­ages per year.

Vintage Public Health Posters That Helped People Take Smart Precautions During Past Crises


We sub­scribe to the the­o­ry that art saves lives even in the best of times.

In the midst of a major pub­lic health cri­sis, art takes a front line posi­tion, com­mu­ni­cat­ing best prac­tices to cit­i­zens with eye catch­ing, easy to under­stand graph­ics and a few well cho­sen words.

In March of 2020, less than 2 weeks after COVID-19 brought New York to its knees, Angeli­na Lip­pert, the Chief Cura­tor of Poster House, one of the city’s new­er muse­ums shared a blog post, con­sid­er­ing the ways in which the CDC’s basic hygiene rec­om­men­da­tions for help­ing stop the spread had been tout­ed to pre­vi­ous gen­er­a­tions.

As she not­ed in a lec­ture on the his­to­ry of the poster as Pub­lic Ser­vice Announce­ment the fol­low­ing month, “mass pub­lic health action… is how we stopped tuber­cu­lo­sis, polio, and oth­er major dis­eases that we don’t even think of today:”

And a major part of erad­i­cat­ing them was edu­cat­ing the pub­lic. That’s real­ly what PSAs are—a means of inform­ing and teach­ing the pub­lic en masse. It goes back to that idea … of not hav­ing to seek out infor­ma­tion, but just being pre­sent­ed with it. Keep­ing the bar­ri­er for entry low means more peo­ple will see and absorb the infor­ma­tion.

The Office of War Infor­ma­tion and the Dis­trict of Colum­bia Soci­ety for the Pre­ven­tion of Blind­ness used an approach­able look­ing rac­coon to con­vince the pub­lic to wash hands in WWII.

Artist Sey­mour Nydorf swapped the rac­coon for a blonde wait­ress with glam­orous red nails in a series of six posters for the U.S. Pub­lic Health Ser­vice of the Fed­er­al Secu­ri­ty Agency

Cough­ing and sneez­ing took posters into some­what gross­er ter­rain.

The New Zealand Depart­ment of Health’s 50s era poster shamed care­less sneez­ers into using a han­kie, and might well have giv­en those in their vicin­i­ty a per­sua­sive rea­son to bypass the buf­fet table.

Great Britain’s Cen­tral Coun­cil for Health Edu­ca­tion and Min­istry of Health col­lab­o­rat­ed with

Her Majesty’s Sta­tionery Office to teach the pub­lic some basic infec­tion math in WWII.

Children’s well­be­ing can be a very per­sua­sive tool. The WPA Fed­er­al Art Project was not play­ing in 1941 when it paired an image of a cheru­bic tot with stern warn­ings to par­ents and oth­er fam­i­ly mem­bers to curb their affec­tion­ate impuls­es, as well as the trans­mis­sion of tuber­cu­lo­sis.

The arrest­ing image packs more of a wal­lop than this earnest and far wordier, ear­ly 20s poster by the Nation­al Child Wel­fare Asso­ci­a­tion and the Nation­al Asso­ci­a­tion for the Study and Pre­ven­tion of Tuber­cu­lo­sis.

17th Century Scientist Gives First Description of Alien Life: Hear Passages from Christiaan Huygens’ Cosmotheoros (1698)

Astro­bi­ol­o­gists can now extrap­o­late the evo­lu­tion­ary char­ac­ter­is­tics of pos­si­ble alien life, should it exist, giv­en the wealth of data avail­able on inter­plan­e­tary con­di­tions. But our ideas about aliens have drawn not from sci­ence but from what Adri­an Hor­ton at The Guardian calls “an engross­ing feed­back loop” of Hol­ly­wood films, comics books, and sci-fi nov­els. A lit­tle over three-hun­dred years ago — hav­ing nev­er heard of H.G. Wells or the X‑Files — Dutch sci­en­tist Chris­ti­aan Huy­gens answered the ques­tion of what alien life might look like in his work Cos­moth­e­o­ros, pub­lished after his death in 1698.

Every­one knows the names Galileo and Isaac New­ton, and near­ly every­one knows their major accom­plish­ments, but we find much less famil­iar­i­ty with Huy­gens, even though his achieve­ments “make him the great­est sci­en­tist in the peri­od between Galileo and New­ton,” notes the Pub­lic Domain Review.

Those achieve­ments include the dis­cov­ery of Saturn’s rings and its moon, Titan, the inven­tion of the first refract­ing tele­scope, a detailed map­ping of the Ori­on Neb­u­la, and some high­ly notable advance­ments in math­e­mat­ics. (Maybe we — Eng­lish speak­ers, that is — find his last name hard to pro­nounce?)

Huy­gens was a rev­o­lu­tion­ary thinker. After Coper­ni­cus, it became clear to him that “our plan­et is just one of many,” as schol­ar Hugo A. van den Berg writes, “and not set apart by any spe­cial con­sid­er­a­tion oth­er than the acci­den­tal fact that we hap­pen to be its inhab­i­tants.” Using the pow­ers of obser­va­tion avail­able to him, he the­o­rized that the inhab­i­tants of Jupiter and Sat­urn (he used the term “Plan­e­tar­i­ans”) must pos­sess “the Art of Nav­i­ga­tion,” espe­cial­ly “in hav­ing so many Moons to direct their Course…. And what a troop of oth­er things fol­low from this allowance? If they have Ships, they must have Sails and Anchors, Ropes, Pil­lies, and Rud­ders…”

“We may well laugh at Huy­gens,” van den Berg writes, “But sure­ly in our own cen­tu­ry, we are equal­ly parochial in our own way. We invari­ably fail to imag­ine what we fail to imag­ine.” Our ideas of aliens fly­ing space­craft already seem quaint giv­en mul­ti­ver­sal and inter­di­men­sion­al modes of trav­el in sci­ence fic­tion. Huy­gens had no cul­tur­al “feed­back loop.” He was mak­ing it up as he went. “In con­trast to Huy­gens’ astro­nom­i­cal works, Cos­moth­e­o­ros is almost entire­ly spec­u­la­tive,” notes van den Berg — though his spec­u­la­tions are through­out informed and guid­ed by sci­en­tif­ic rea­son­ing.

To under­mine the idea of Earth as spe­cial, cen­tral, and unique, “a thing that no Rea­son will per­mit,” Huy­gens wrote — meant pos­ing a poten­tial threat to “those whose Igno­rance or Zeal is too great.” There­fore, he willed his broth­er to pub­lish Cos­moth­e­o­ros after his death so that he might avoid the fate of Galileo. Already out of favor with Louis XIV, whom Huy­gens had served as a gov­ern­ment sci­en­tist, he wrote the book while back at home in The Hague, “fre­quent­ly ill with depres­sions and fevers,” writes the Pub­lic Domain Review. What did Huy­gens see in his cos­mic imag­i­na­tion of the sail­ing inhab­i­tants of Jupiter and Sat­urn? Hear for your­self above in a read­ing of Huy­gens’ Cos­moth­e­o­ros from Voic­es of the Past.

Huy­gens’ descrip­tions of intel­li­gent alien life derive from his lim­it­ed obser­va­tions about human and ani­mal life, and so he pro­pos­es the neces­si­ty of human-like hands and oth­er appendages, and rules out such things as an “elephant’s pro­boscis.” (He is par­tic­u­lar­ly fix­at­ed on hands, though some alien humanoids might also devel­op wings, he the­o­rizes.) Like all alien sto­ries to come, Huy­gens’ spec­u­la­tions, how­ev­er log­i­cal­ly he presents them, say “more about our­selves,” as Hor­ton writes, “our fears, our anx­i­eties, our hope, our adapt­abil­i­ty — than any poten­tial out­side vis­i­tor.” His descrip­tions show that while he did not need to place Earth at the cen­ter of the cos­mos, he mea­sured the cos­mos accord­ing to a very human scale.

Mattel’s Barbie Turns Women of Medicine, Including COVID Vaccine Developer, Into Dolls

The multi­na­tion­al toy man­u­fac­tur­er Mat­tel is encour­ag­ing young­sters to play doc­tor — not a euphemism — and hon­or­ing first respon­ders with the recent release of three health­care-themed “Career Bar­bi­es.”

The com­pa­ny is putting its mon­ey where its mouth is by donat­ing $5 to the First Respon­ders Children’s Foun­da­tion for every doc­tor, para­medic, or nurse Bar­bie pur­chased at Tar­get through August 28.

Mat­tel has also iden­ti­fied six female health­care pio­neers whose efforts dur­ing the pan­dem­ic mer­it a one-of-a-kind Bar­bie who shares their like­ness.

Vac­ci­nol­o­gist Sarah Gilbert, who led the team that devel­oped the Oxford/AstraZeneca vac­cine, describes this unex­pect­ed hon­or as “a very strange con­cept” (pre­sum­ably as com­pared to being award­ed a dame­hood or receiv­ing a stand­ing ova­tion at Wim­ble­don.)

The 59-year-old Oxford Uni­ver­si­ty pro­fes­sor added that she hoped the char­ac­ter­is­ti­cal­ly smooth plas­tic doll would be “part of mak­ing it more nor­mal for girls to think about careers in sci­ence, although, to be hon­est, when I was a young girl I nev­er believed that I would­n’t have a career in sci­ence.”

If the doll falls short of inspir­ing girls to con­sid­er a career in STEM, Women in Sci­ence & Engi­neer­ing (WISE), the non­prof­it orga­ni­za­tion Pro­fes­sor Gilbert chose to receive a dona­tion from Mat­tel on her behalf, can take up the slack.

One of the most com­pelling of the six cus­tom-made Front Line Respon­der Bar­bi­es is based on vet­er­an nurse Amy O’Sullivan, a heav­i­ly tat­tooed, queer moth­er of three, who cared for the first COVID-19 patient (soon to become New York City’s first offi­cial COVID death) in Brooklyn’s Wycoff Hos­pi­tal.

Soon there­after, she sur­vived being put on a ven­ti­la­tor with COVID her­self, even­tu­al­ly wind­ing up on the cov­er of Time Mag­a­zine, in the same neck­er­chief, flo­ral socks, eye catch­ing sur­gi­cal cap and woven bracelets her tiny scrub-suit­ed dop­pel­ganger wears.

Sure­ly Amy O’Sullivan is a bet­ter all around role mod­el than the sim­i­lar­ly inked Toki­do­ki Bar­bie or Total­ly Tat­too Bar­bie, or for that mat­ter, the non-cus­tom made First Respon­der Nurse, whose descrip­tion on Target’s web­site seems a bit ret­ro­grade, giv­en the events of the last year and a half:

Wear­ing cute scrubs fea­tur­ing a med­ical-tool print top, pink pants and white shoes, Bar­bie nurse doll (12-in/30.40-cm) is ready make her rounds and check on patients!

The real life O’Sullivan, who was very involved in the cre­ation of her cus­tom doll, seems tick­led by Mattel’s faith­ful recre­ation, telling The New York Post:

When I was younger I always felt like an out­sider — nobody ever looked like me, talked like me, walked like me. I had no role mod­el at all when I was grow­ing up. So if I can be some lit­tle girl’s role mod­el that feels like this, I would love that. 

Nurse O’Sullivan had stronger words for those who have aged out of the demo­graph­ic, in a recent inter­view with Time:

I see these young peo­ple not wear­ing masks. And, you know, those are the peo­ple that COVID is affect­ing now, the younger gen­er­a­tion. They’re becom­ing very sick. And it’s nev­er going to go away until we get vac­ci­nat­ed and wear masks.

That might be a bit heavy for those on the younger end of Career Bar­bi­e’s rec­om­mend­ed 3 and up age group (“espe­cial­ly those inter­est­ed in care­tak­ing and help­ing oth­ers!”), but hope­ful­ly her words will car­ry some weight with those respon­si­ble for pro­tect­ing those chil­dren.

The oth­er cus­tom-made Bar­bi­es hon­or:
