Meet Grace Hopper, the Pioneering Computer Scientist Who Helped Invent COBOL and Build the Historic Mark I Computer (1906–1992)

On a page for its School of Tech­nol­o­gy, Ras­mussen Col­lege lists six “Assump­tions to Avoid” for women who want to enter the field of com­put­er sci­ence. I couldn’t com­ment on whether these “assump­tions” (alleged mis­con­cep­tions like “the work envi­ron­ment is hos­tile to women”) are actu­al­ly dis­proved by the com­men­tary. But I might sug­gest a sev­enth “assump­tion to avoid”—that women haven’t always been com­put­er sci­en­tists, inte­gral to the devel­op­ment of the com­put­er, pro­gram­ming lan­guages, and every oth­er aspect of com­put­ing, even 100 years before com­put­ers exist­ed.

In fact, one of the most notable women in com­put­er sci­ence, Grace Hop­per, served as a mem­ber of the Har­vard team that built the first com­put­er, the room-sized Mark I designed in 1944 by physics pro­fes­sor Howard Aiken. Hop­per also helped devel­op COBOL, the first uni­ver­sal pro­gram­ming lan­guage for busi­ness, still wide­ly in use today, a sys­tem based on writ­ten Eng­lish rather than on sym­bols or num­bers. And she is cred­it­ed with coin­ing the term “com­put­er bug” (and by exten­sion “debug”), when she and her asso­ciates found a moth stuck inside the Mark II in 1947. (“From then on,” she told Time mag­a­zine in 1984, “when any­thing went wrong with a com­put­er, we said it had bugs in it.”)

These are but a few of her achieve­ments in a com­put­er sci­ence career that spanned more than 42 years, dur­ing which time she rose through the ranks of the Naval Reserves, then lat­er active naval duty, retir­ing as the old­est com­mis­sioned offi­cer, a rear admi­ral, at age 79.

In addi­tion to win­ning dis­tin­guished awards and com­men­da­tions over the course of her career—including the first-ever com­put­er sci­ence “Man of the Year” award—Hopper also acquired a few dis­tin­guished nick­names, includ­ing “Amaz­ing Grace” and “Grand­ma COBOL.” She may become known to a new gen­er­a­tion by the nick­name, “Queen of Code,” the title of a recent doc­u­men­tary from FiveThirtyEight’s “Sig­nals” series. Direct­ed by Com­mu­ni­ty star Gillian Jacobs, the short film, which you can watch in full here, tells the sto­ry of her “inim­itable lega­cy as a bril­liant pro­gram­mer and pio­neer­ing woman in a male-dom­i­nat­ed field,” writes Alli­son McCann at FiveThir­tyEight.

Hopper’s name may be “mys­te­ri­ous­ly absent from many his­to­ry books,” as Amy Poehler’s Smart Girls notes, but before her death in 1992, she was intro­duced to mil­lions through TV appear­ances on shows like Late Night with David Let­ter­man (top) and 60 Min­utes, just above. As you’ll see in these clips, Hop­per wasn’t just a crack math­e­mati­cian and pro­gram­mer but also an ace pub­lic speak­er whose dead­pan humor cracked up Let­ter­man and the groups of stu­dents and fel­low sci­en­tists she fre­quent­ly addressed.

The 60 Min­utes seg­ment notes that Hop­per became “one of that small band of broth­ers and sis­ters who ush­ered in the com­put­er rev­o­lu­tion” when she left her professor’s job at Vas­sar at the start of WWII to serve in the Naval Reserve, where she was assigned to the Bureau of Ships Com­pu­ta­tion Project at Har­vard. But she nev­er stopped being an edu­ca­tor and con­sid­ered “train­ing young peo­ple” her sec­ond-most impor­tant accom­plish­ment. In this, her lega­cy lives on as well.

The world’s largest gath­er­ing of women tech­nol­o­gists is called “The Grace Hop­per Cel­e­bra­tion.” And a doc­u­men­tary in pro­duc­tion called Born with Curios­i­ty (see a teas­er above) hopes that “shin­ing a light on and human­iz­ing role mod­els like Grace makes them relat­able in a way that inspires oth­ers to great­ness.” At a time when women make up the low­est enroll­ment in com­put­er sci­ence out of all of the STEM fields, Hopper’s exam­ple and encour­age­ment may be much need­ed.

Computer Scientists Figure Out What’s the Longest Distance You Could Sail at Sea Without Hitting Land

Back in 2012, a red­di­tor by the name of “Kepleron­ly­knows” won­dered what’s the longest dis­tance you could trav­el by sea with­out hit­ting land. And then s/he haz­ard­ed an edu­cat­ed guess: “you can sail almost 20,000 miles in a straight line from Pak­istan to the Kam­chat­ka Penin­su­la, Rus­sia.”

Six years lat­er, two com­put­er scientists–Rohan Chabuk­swar (Unit­ed Tech­nolo­gies Research Cen­ter in Ire­land) and Kushal Mukher­jee (IBM Research in India)–have devel­oped an algo­rithm that offers a more defin­i­tive answer. Accord­ing to their com­pu­ta­tions, “Kepleron­ly­knows was entire­ly cor­rect,” notes the MIT Tech­nol­o­gy Review.

The longest path over water “begins in Son­mi­ani, Balochis­tan, Pak­istan, pass­es between Africa and Mada­gas­car and then between Antarc­ti­ca and Tier­ra del Fuego in South Amer­i­ca, and ends in the Kara­gin­sky Dis­trict, Kam­chat­ka Krai, in Rus­sia. It is 32,089.7 kilo­me­ters long.” Or 19,939 miles.

While they were at it, Chabuk­swar and Mukher­jee also deter­mined the longest land jour­ney you could take with­out hit­ting the sea. That path, again notes the MIT Tech­nol­o­gy Review, “runs from near Jin­jiang, Fujian, in Chi­na, weaves through Mon­go­lia Kaza­khstan and Rus­sia, and final­ly reach­es Europe to fin­ish near Sagres in Por­tu­gal. In total the route pass­es through 15 coun­tries over 11,241.1 kilo­me­ters.” Or 6,984 miles. You can read Chabuk­swar and Mukher­jee’s research report here.

Infographics Show How the Different Fields of Biology, Chemistry, Mathematics, Physics & Computer Science Fit Together

Ask any­one who’s pur­sued a career in the sci­ences what first piqued their inter­est in what would become their field, and they’ll almost cer­tain­ly have a sto­ry. Gaz­ing at the stars on a camp­ing trip, rais­ing a pet frog, fool­ing around with com­put­ers and their com­po­nents: an expe­ri­ence sparks a desire for knowl­edge and under­stand­ing, and the pur­suit of that desire even­tu­al­ly deliv­ers one to their spe­cif­ic area of spe­cial­iza­tion.

Or, as they say in sci­ence, at least it works that way in the­o­ry; the real­i­ty usu­al­ly unrolls less smooth­ly. On such a jour­ney, just like any oth­er, it might help to have a map.

Enter the work of sci­ence writer and physi­cist Dominic Wal­li­man, whose ani­mat­ed work on the Youtube chan­nel Domain of Sci­ence we’ve pre­vi­ous­ly fea­tured here on Open Cul­ture. (See the “Relat­ed Con­tent” sec­tion below for the links.)

Wal­li­man’s videos astute­ly explain how the sub­fields of biol­o­gy, chem­istry, math­e­mat­ics, physics, and com­put­er sci­ence relate to each oth­er, but now he’s turned that same mate­r­i­al into info­graph­ics read­able at a glance: maps, essen­tial­ly, of the intel­lec­tu­al ter­ri­to­ry. He’s made these maps, of biol­o­gy, chem­istry, math­e­mat­ics, physics, and com­put­er sci­ence, freely avail­able on his Flickr account: you can view them all on a sin­gle page here along with a few more of his info­graph­ics..

As much use as Wal­li­man’s maps might be to sci­ence-mind­ed young­sters look­ing for the best way to direct their fas­ci­na­tions into a prop­er course of study, they also offer a help­ful reminder to those far­ther down the path — espe­cial­ly those who’ve strug­gled with the blind­ers of hyper­spe­cial­iza­tion — of where their work fits in the grand scheme of things. No mat­ter one’s field, sci­en­tif­ic or oth­er­wise, one always labors under the threat of los­ing sight of the for­est for the trees. Or the realm of life for the bioin­for­mat­ics, bio­physics, and bio­math­e­mat­ics; the whole of math­e­mat­ics for the num­ber the­o­ry, the dif­fer­en­tial geom­e­try, and the dif­fer­en­tial equa­tions; the work­ings of com­put­ers for the sched­ul­ing, the opti­miza­tion, and the boolean sat­is­fi­a­bil­i­ty.

David Lynch Teaches Typing: A New Interactive Comedy Game

Typ­ing pro­grams demand some patience on the part of the stu­dent, and David Lynch Teach­es Typ­ing is no excep­tion.

You’ve got 90 sec­onds to get accli­mat­ed to the crud­dy flop­py disc-era graph­ics and the cacoph­o­nous voice of your instruc­tor, a dead ringer for FBI Deputy Direc­tor Gor­don Cole, the hard-of-hear­ing char­ac­ter direc­tor David Lynch played on his sem­i­nal ear­ly 90s series, Twin Peaks.

Things perk up about a minute and a half in, when stu­dents are instruct­ed to place their left ring fin­gers in an undu­lat­ing bug to the left of their key­boards.

That sec­ond “in”? Not a typo (though you’ll notice plen­ty of no doubt inten­tion­al boo-boos in the teacher’s pre-pro­grammed respons­es…)

The bug in ques­tion may well put you in mind of the mys­te­ri­ous baby in Lynch’s first fea­ture length film, 1977’s Eraser­head.

On the oth­er hand, it might not.

David Lynch Teach­es Typ­ing is actu­al­ly a short inter­ac­tive com­e­dy game, and many of the mil­len­ni­al review­ers cov­er­ing that beat have had to play catch-up in order to catch the many nods to the director’s work con­tained there­in.

One of our favorites is the Apple-esque name of the program’s retro com­put­er, and we’ll wager that fre­quent Lynch col­lab­o­ra­tor, actor Kyle MacLach­lan, would agree.

Anoth­er ref­er­ence that has thus far elud­ed online gam­ing enthu­si­asts in their 20s is Mavis Bea­con Teach­es Typ­ing. Take a peek below at what the vir­tu­al typ­ing tutor’s graph­ics looked like around the time the orig­i­nal Twin Peaks aired to dis­cov­er the cre­ators of David Lynch Teach­es Typ­ing’s oth­er inspi­ra­tion.

David Lynch Teach­es Typ­ing is avail­able for free down­load here. If you’re anx­ious that doing so might open you up to a tech­ni­cal bug of night­mar­ish pro­por­tions, stick with watch­ing the play through at the top of the page.
