The (Beautiful) Physics of Adding Cream to Your Coffee

Here’s a quick sce­nario for you. You’ve poured your­self a fresh cup of black cof­fee, and you want to keep it hot until you’re ready to drink it. Are you mak­ing a mis­take by adding cream to that cof­fee? Does cof­fee with cream cool faster than black cof­fee left alone? Intu­ition says yes. The laws of physics lead to a dif­fer­ent con­clu­sion.

Last year, the web site Mod­ernist Cui­sine gave three rea­sons why “cof­fee with cream cools about 20% slow­er than black cof­fee” alone. To sum­ma­rize:

1) Black cof­fee is dark­er, and dark col­ors emit heat faster than light col­ors. As such, “by light­en­ing the col­or of your cof­fee, you slow the rate at which it cools,” if only slight­ly.

2) The Ste­fan-Boltz­mann Law (appar­ent­ly) says that hot­ter sur­faces radi­ate heat faster— than cool­er ones. So if you add cream to a cup of black cof­fee, it might low­er the tem­per­a­ture of that cup of cof­fee. How­ev­er that cup could still cool at a slow­er rate than a cup of hot black cof­fee.

3) Final­ly, and per­haps most impor­tant­ly, “adding cream thick­ens the cof­fee (adds vis­cos­i­ty), so it evap­o­rates slow­er.” And, in turn, less heat gets car­ried away by the evap­o­ra­tion.

To top things off, Mod­ernist Cui­sine also pro­duced a video show­ing cream being poured into cof­fee in super slow motion. Even if you don’t care to con­sid­er the physics of cof­fee & cream, it’s pret­ty cool to watch an aver­age cup of joe get­ting turned into a roil­ing sea.

Cancer Patients’ Extreme Makeovers Let Them To Forget Their Illness ‘If Only For A Second’

The sea­son of giv­ing can be an unseem­ly time for non­prof­its. As New Year’s approach­es, every char­i­ta­ble insti­tu­tion down in Char­i­ta­ble Insti­tu­tionville must bang its tar-tin­ker and blow its hoo-hoover, in hope of dona­tions.

No doubt they’re all deserv­ing, but the onslaught of requests can leave sup­port­ers feel­ing a bit Grinchy. When that hap­pens, I rec­om­mend the video above, which doc­u­ments a hoax of Borat-like pro­por­tions. The per­pe­tra­tor is the Mimi Foun­da­tion, a Bel­gium-based group that offers psy­cho­log­i­cal coun­sel­ing, beau­ty treat­ments, and hair­style tips to peo­ple with can­cer.

The unsus­pect­ing vic­tims? Twen­ty can­cer patients who took it on good faith that they were being treat­ed to stan­dard makeovers, the sort of pro­fes­sion­al artistry that cre­ates an illu­sion of health, what many think pass­es for nor­mal­cy. All the Mimi Foun­da­tion asked for in return was that the recip­i­ents keep their eyes closed as the mag­ic was being worked.

Mean­while, pho­tog­ra­ph­er Vin­cent Dixon crouched behind a one-way mir­ror, poised to cap­ture each sit­ters’ reac­tion to his or her trans­for­ma­tion.

One does­n’t want to say too much. The end results are not what you think, unless you were think­ing of one of those over-the-top bizarre Amer­i­ca’s Next Top Mod­el pho­to chal­lenges.

Dixon’s images record the shock and invol­un­tary spon­tane­ity. The video, called “If Only for a Sec­ond, shows those ini­tial respons­es blos­som­ing into …well, let’s just say the Mimi Foun­da­tion, assist­ed by a pha­lanx of styl­ists, achieved their goal.

Hear King Edward VIII Explain Why He Abdicated The Crown For Love, 77 Years Ago Today

Sev­en­ty-sev­en years ago, in a move unprece­dent­ed since the Glo­ri­ous Rev­o­lu­tion of 1688, King-Emper­or Edward VIII abdi­cat­ed the throne. Today’s audi­ences will rec­og­nize the episode from The King’s Speech: less than a year after hav­ing ascend­ed to the British king­ship in Jan­u­ary of 1936, Edward became roman­ti­cal­ly entan­gled with a yet-to-be-divorced Amer­i­can socialite named Wal­lis Simp­son. As long as the King’s liaisons remained dis­creet, the cou­ple was afford­ed a respectable amount of pri­va­cy by the roy­al fam­i­ly and the British media. Things grew more com­pli­cat­ed, how­ev­er, when Simp­son divorced her sec­ond hus­band in Octo­ber of 1936, and the pair decid­ed to mar­ry, come hell or high water.

A King of the Unit­ed King­dom of Great Britain and North­ern Ire­land being wed­ded to a twice-divorced Amer­i­can socialite would have caused a furor. As the head of the Church of Eng­land, Edward could not mar­ry a divorced woman whose for­mer hus­band (let alone hus­bands) remained alive. Simpson’s first divorce proved even more problematic—it was grant­ed based on “emo­tion­al incom­pat­i­bil­i­ty,” and may not have been rec­og­nized under both Church and Eng­lish law. The King’s mar­riage to Simp­son also raised the pos­si­bil­i­ty of an Amer­i­can Queen, a sac­ri­le­gious idea in the eyes of his sub­jects.

Faced with a choice between the crown and his love, Edward VIII chose to step down. On Decem­ber 10, 1936, the King signed the fol­low­ing dec­la­ra­tion of abdi­ca­tion:

Edward_abdication

In the audio clip at the top of the post, Edward VIII takes to the radio waves to declare his abdi­ca­tion on Decem­ber 11. Brim­ming with hard­ly-con­tained emo­tion, Edward attempts to explain his rea­sons to the British peo­ple (read the full tran­script here):

“You all know the rea­sons which have impelled me to renounce the Throne. But I want you to under­stand that in mak­ing up my mind I did not for­get the coun­try or the Empire which as Prince of Wales, and late­ly as King, I have for twen­ty-five years tried to serve. But you must believe me when I tell you that I have found it impos­si­ble to car­ry the heavy bur­den of respon­si­bil­i­ty and to dis­charge my duties as King as I would wish to do with­out the help and sup­port of the woman I love.”

For those who had doubts about Simpson’s true feel­ings for the King (some sus­pect­ed her of car­ing only about the king’s mon­ey), the next 35 years would pro­vide suf­fi­cient proof. The pair remained mar­ried until Edward’s death in 1972.

Gustave Doré’s Exquisite Engravings of Cervantes’ Don Quixote

QuixoteandPanza

In a now defunct list­ing from Bau­man Rare Books for an 1868 edi­tion of Miguel de Cer­vantes’ Don Quixote with illus­tra­tions by Gus­tave Doré, we find the fol­low­ing unat­trib­uted quo­ta­tion: “in every Eng­lish-speak­ing home where they can spell the word ‘art,’ you will find Doré edi­tions.” It’s odd that the homes should be “Eng­lish-speak­ing” when Doré’s illus­tra­tions were orig­i­nal­ly an 1860 French com­mis­sion, but the quote at least demon­strates the enor­mous pop­u­lar­i­ty of Doré’s Quixote. His ren­der­ings were so influ­en­tial they deter­mined the look of Quixote and San­cho Pan­za in many sub­se­quent illus­trat­ed ver­sions, stage and film pro­duc­tions, and read­ers’ imag­i­na­tions.

Per­haps the most suc­cess­ful illus­tra­tor of the 19th cen­tu­ry, the dap­per Doré was also at work on a momen­tous commission—this time from an Eng­lish publisher—to illus­trate the Bible. He went on to edi­tions of Rime of the Ancient Mariner, Par­adise Lost, The Divine Com­e­dy, Poe’s The Raven, and many oth­er famous works of lit­er­a­ture. But his Don Quixote may be the lit­er­ary com­mis­sion for which he’s best remem­bered.

QuixoteCaged

Doré appar­ent­ly entered a crowd­ed field when he took on Cer­vantes’ foun­da­tion­al text. For a lit­tle con­text, Bau­man Rare Books also quotes a cer­tain schol­ar sur­named “Ray,” who offers this pré­cis of the edition’s cre­ation:

Don Quixote was a text cal­cu­lat­ed to test even Doré. He was match­ing him­self against Coypel and Tony Johan­not, not to men­tion the Span­ish illus­tra­tors of the great Ibar­ra edi­tion pub­lished in Madrid in 1780. He met the chal­lenge superbly… At first he intend­ed only 40 designs, but Cer­vantes’ book cap­tured his imag­i­na­tion, and he arranged for a major work… Don Quixote and San­cho Pan­za reached their defin­i­tive ren­der­ing in Doré’s designs.

Doré end­ed up com­plet­ing over 200 illus­tra­tions for his edi­tion. You can see a cou­ple of those “defin­i­tive,” and exquis­ite, engrav­ings above and below. The edi­tors of Bib­liokept main­tain a sep­a­rate site post­ing all of the Doré Quixote illus­tra­tions. Project Guten­berg has an Eng­lish full text Quixote with the illus­tra­tions scanned in, and the Uni­ver­si­ty of Buf­fa­lo has an exten­sive search­able dig­i­tal col­lec­tion of Doré illus­tra­tions. And if you just have to con­form to the tastes of “every Eng­lish-speak­ing home where they can spell the word ‘art’ ” and own a Doré Quixote of your own, you can pur­chase a re-cre­ation of an 1870 edi­tion for only three month­ly install­ments of $125. It’s a “pub­lish­ing trea­sure.” Prince­ton Uni­ver­si­ty has more infor­ma­tion on the engrav­ings.

Google’s Moving Ad About 1947 Partition of India & Pakistan Tops 10 Million Views

Recent­ly, Wired writer Steve Sil­ber­man (aka @stevesil­ber­man) shot us a note on Twit­ter, say­ing, “@openculture, do not miss this bril­liant ad. Most touch­ing movie (in 3 mins!) I’ve seen in years.” Released on Novem­ber 13th, the video has already clocked over 10 mil­lion views. But chances are you haven’t seen it. And that’s because it’s tar­get­ed to the web-enabled mid­dle class of India and Pak­istan. As The Dawn, Pak­istan’s old­est Eng­lish news­pa­per, describes it, the Google-cre­at­ed ad enti­tled “Reunion “por­trays two child­hood friends, now elder­ly men, who haven’t seen each oth­er since they were sep­a­rat­ed by the 1947 par­ti­tion that cre­at­ed India and Pak­istan from the old British empire in South Asia. Par­ti­tion sparked a mass exo­dus as mil­lions of Mus­lims and Hin­dus fled across the new bor­ders amid reli­gious vio­lence.” Now Google search prod­ucts are help­ing to bring old friends and neigh­bors back togeth­er.

Cyn­ics may be quick to judge this a sac­cha­rine, manip­u­la­tive ad. But oth­ers are see­ing in it some­thing else — a sign that “per­son­al con­nec­tions between Indi­ans and Pak­ista­nis run deep.” Even if their gov­ern­ments gain some­thing from keep­ing the con­flict alive, every­day peo­ple in India and Pak­istan are increas­ing­ly ready to put his­to­ry aside.

Note: If you click CC at the bot­tom of the video, you can use cap­tions to trans­late the film into nine lan­guages, includ­ing French, Malay­alam and Urdu. It is pre­set to Eng­lish.

The Clash Mauls a Teddy Bear and Plays Two Songs on The Tom Snyder Show (1981)

The Clash’s San­din­ista!, their fourth and penul­ti­mate stu­dio album (let’s not talk about Cut the Crap) inspired crit­i­cal rhap­sodies and rose to the top of lists every­where in 1981. When I encoun­tered it almost ten years lat­er as a young fan, I didn’t give it much of a chance, except for a song with the same name as my belea­guered hometown’s NBA team. In hind­sight, it was my loss, but it’s also true that near­ly every gen­er­a­tion of Clash fans, includ­ing the very first, has put their fin­ger on the band’s moment of either “sell­ing out” or sharply declin­ing. Maybe for me it was what a Rolling Stone review called San­din­ista!’s “main­stream moves” and “stu­dio sophis­ti­ca­tion.” Maybe it was the “whiff of grandeur” of the triple album. I think it also had to do with what Tom Sny­der, in his 1981 inter­view with the band above, says of them in his intro­duc­tion: they pre­ferred to be iden­ti­fied “not so much as a Rock and Roll group but as a ‘News-giv­ing group.’”

It was hard­ly news when I heard it, and I didn’t much care for top­i­cal songs any­way. But I’ve always admired Joe Strummer’s sin­cer­i­ty and sense of polit­i­cal urgency. I don’t know how seri­ous­ly Strum­mer takes Snyder’s “News-giv­ing” open, but he rolls with it, and the band turns on the charm offen­sive, alter­nate­ly cud­dling and abus­ing a ted­dy bear (against Snyder’s protes­ta­tions), pro­fess­ing their sin­cere loy­al­ty to their fans, and cov­er­ing the host with mer­chan­dise. It’s a fun eight and half min­utes. Then they do two songs, “The Mag­nif­i­cent Sev­en” (above), from San­din­ista!, and “This is Radio Clash” (below), which doesn’t appear on any of their stu­dio albums. Behind Mick Jones’ wall of amps, pio­neer­ing graf­fi­ti artist Futu­ra 2000 spray-paints some uniden­ti­fi­able words, and beneath the whole affair is what Dan­ger­ous Minds calls “an under­cur­rent of con­trolled may­hem.” This kind of TV just doesn’t hap­pen any­more.

View Bill Gates’ Mobile Library: The Books & Courses That Help Him Change The World

Step­ping down as Microsoft’s chief exec­u­tive offi­cer in 2000 had giv­en Bill Gates some extra time, which the auto­di­dact imme­di­ate­ly expend­ed by attempt­ing to learn… well, every­thing. Per­haps Gates threw him­self at learn­ing to make up for aban­don­ing col­lege for greater pursuits—he attend­ed Har­vard but left after two years’ study to pur­sue his pas­sion for com­put­ers. What­ev­er his rea­sons, Gates has begun to assid­u­ous­ly learn all he can about the world, and is record­ing his edu­ca­tion process for pos­ter­i­ty on his web­site, The Gates Notes. As the video above explains, Microsoft’s founder has lis­tened to hun­dreds of hours of uni­ver­si­ty lec­tures from The Teach­ing Com­pa­ny; he got hooked after lis­ten­ing to Robert Whap­les’ Mod­ern Eco­nom­ic Issues and breez­ing through Tim­o­thy Tay­lor’s Amer­i­ca and the New Glob­al Econ­o­my. His num­ber one pick? Big His­to­ry which is taught by David Chris­t­ian and, Gates says, “is still my favorite course of all. The course is so broad that it syn­the­sizes the his­to­ry of every­thing includ­ing the sci­ences into one frame­work.”

Wher­ev­er Gates trav­els, he is also eter­nal­ly accom­pa­nied by his read­ing bag. Sur­prised that the her­ald of the dig­i­tal age is pack­ing paper­backs? Don’t be. “I’m still pret­ty much an old-school print guy,” Gates writes, “because I like to jot notes in the mar­gins, but I assume I’ll move over to ebooks when anno­ta­tion fea­tures get bet­ter.”

Last week, Gates showed WIRED the con­tents of his decid­ed­ly 20th cen­tu­ry mobile library. The books, which Gates replen­ish­es at an impres­sive rate, encom­pass an admirable breadth of top­ics. As befit­ting the over­seer of the Bill and Melin­da Gates Foun­da­tion, the major­i­ty of Gates’ read­ing con­sists of non-fic­tion (only Gary Shteyn­gart’s recent nov­el made the fic­tion cut this round). His­to­ry, psy­chol­o­gy, sci­ence, sound busi­ness coun­sel, soci­ol­o­gy, eco­nom­ics, and his­to­ry all make up the dizzy­ing array of Gates’ every­day read­ing. Here is a selec­tion from WIRED’s par­tial list, includ­ing Gates’ own com­ments on the impor­tance of each choice:

-Feynman’s Tips on Physics by Richard Feyn­man– A short com­pan­ion book to Richard Feynman’s clas­sic Lec­tures on Physics. Always worth­while to return to the feet of the mas­ter.

-Super Sad True Love Sto­ry: A Nov­el by Gary Shteyn­gart– I don’t read a lot of fic­tion, but I thought this was an inter­est­ing study of the moral impli­ca­tions of tech­nol­o­gy. Will tech­nol­o­gy con­tribute to everyone’s well-being or just make peo­ple more nar­cis­sis­tic?

-The Car­toon Intro­duc­tion to Sta­tis­tics by Grady Klein– Bought this to use with one of my kids. Help­ful in explain­ing a com­pli­cat­ed sub­ject to a teenag­er.

-The Path Between the Seas: The Cre­ation of the Pana­ma Canal by David McCul­lough – I read this to pre­pare for a fam­i­ly vaca­tion to Pana­ma. It’s pure McCul­lough: epic dra­ma, polit­i­cal intrigue, heart­break­ing defeats, and even­tu­al tri­umph.

-The Bet­ter Angels of Our Nature: Why Vio­lence Has Declined by Steven Pinker– One of the most impor­tant books I’ve read. Steven Pinker demon­strates how the world evolved to be far less vio­lent. Coun­ter­in­tu­itive, if you watch the news, but true.

We’ve also used the trusty Con­trol + Scroll func­tion to zoom in and name a few addi­tion­al titles:

Howard Zinn’s “What the Classroom Didn’t Teach Me About the American Empire”: An Illustrated Video Narrated by Viggo Mortensen

“Through­out U.S. his­to­ry, our mil­i­tary has been used not for moral pur­pos­es but to expand eco­nom­ic, polit­i­cal, and mil­i­tary pow­er,” says a car­toon Howard Zinn in Mike Konopacki’s 273-page com­ic book A People’s His­to­ry of Amer­i­can Empire. Writ­ten with Zinn and his­to­ri­an Paul Buh­le, the book adapts Zinn’s path­break­ing his­to­ry from below, A People’s His­to­ry of the Unit­ed States, and his auto­bi­og­ra­phy You Can’t be Neu­tral on a Mov­ing Train in a direct exam­i­na­tion of the U.S. Imperi­um. Konopac­ki calls the book his “answer” to the text­books of “the pow­er struc­ture.” (Explore high­lights from the com­ic his­to­ry here.)

Above, you can see a short video adap­ta­tion of some key text from A People’s His­to­ry of Amer­i­can Empire. Nar­rat­ed by Vig­go Mortensen, the video gives us a nut­shell ver­sion of Zinn’s cul­tur­al, polit­i­cal, and moral education—what the Ger­mans used to call bil­dung—as he grows from a some­what naive WWII bomber pilot, to a col­lege stu­dent on the G.I. Bill, to a grad­u­ate stu­dent, then pro­fes­sor, of his­to­ry.

Along the way he notices that the map in every text­book labeled “West­ern Expan­sion” shows “the march across the con­ti­nent as a nat­ur­al, almost bio­log­i­cal phe­nom­e­non”:

That huge acqui­si­tion of land called the Louisiana Pur­chase gave no hint of any­thing but vacant land acquired, no sense that this ter­ri­to­ry was occu­pied by hun­dreds of Indi­an tribes that would have to be anni­hi­lat­ed or forced out of their homes in what we now call eth­nic cleans­ing.

Zinn goes on to chart the rise of U.S. Impe­ri­al­ism into the twen­ti­eth cen­tu­ry as the increas­ing­ly mil­i­ta­rized nation seizes Mex­i­can ter­ri­to­ry and invades Cuba and the Philip­pines. Then we come to the osten­si­bly anti-com­mu­nist “police actions” in Korea and Viet­nam, and Zinn’s high­ly influ­en­tial 1967 book Viet­nam: The Log­ic of With­draw­al. When entrust­ed by Daniel Ells­berg with hun­dreds of pages of the Pen­ta­gon Papers, Zinn learns that the war in Viet­nam is large­ly waged for the same rea­sons as our oth­er impe­ri­al­ist moves abroad: the papers “spoke blunt­ly of the U.S. motives as a quest for tin, rub­ber, oil.”

But what of the war Zinn begins with, the war in which he fought? Near the end of the short film, he returns to his days as a WWII bomber, when he heard a fel­low pilot argue that the U.S. was as “moti­vat­ed by ambi­tions of con­trol and con­quest” as its ene­mies. He dis­agreed at the time, but in the inter­ven­ing years came to see his fel­low airman’s point. What we get with our ide­al­ism about any war, Zinn says, is a seem­ing “Impe­ri­al­ism lite,” whose motives are benign. Soft pow­er, we’re told, wins the day now. But peel back the cur­tain on our actions in the world, and we will see the same atroc­i­ties, the same cru­el­ties, and the same basic moti­va­tions as every oth­er act of impe­ri­al­ist aggres­sion.
