"The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then — to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn." — T.H. White, The Once and Future King

Taking the Earth’s Temperature

How do we mea­sure our planet’s global mean tem­per­a­ture, and com­pare it to a record dat­ing back hun­dreds of thou­sands of years, a com­par­i­son cen­tral to dis­cus­sions about cli­mate change? Jor­dan R. Raney’s descrip­tion of the inge­nious but impaired proxy mea­sures from tree rings to coral reefs are meant to encour­age skep­ti­cism for some of the more extreme claims that have been made. Unfor­tu­nately, we still need to make deci­sions about cli­mate change, how­ever incom­plete, uncer­tain the data we have is. In fact, that is the challenge.

Why is laughter almost non-existent in ancient Greek sculpture?

Elec­tri­cal Engi­neer­ing pro­fes­sor Yan­nis Tsi­vidis inno­cently asks, why is it that we very rarely see laugh­ter depicted in ancient Greek sculp­ture? From the range of schol­arly answers, you get the pecu­liar sense that we “mod­erns” are not in a posi­tion to give an answer.

No Heaven on Earth

Why are so many of us so skep­ti­cal when con­fronted with the over­whelm­ing evi­dence for envi­ron­men­tal con­se­quences of destroy­ing every­thing we come in con­tact with? In her review of Amer­i­can Earth, an anthol­ogy of Amer­i­can envi­ron­men­tal­ist views, Ver­lyn Klinkenborg has this reac­tion to the bar­rage of evi­dence and entreaties to recon­nect with nature:

After a day or two, I found myself read­ing this anthol­ogy as if it were a series of reports from a dis­tant planet in a dis­tant time — as an appen­dix, per­haps, to Doris Lessing’s Cano­pus in Argos nov­els. Read­ing Amer­i­can Earth in that light helped make sev­eral things clear. First, each doc­u­ment in the vol­ume is a minor­ity report — some­times a minor­ity of one. The assump­tions, the hopes, the argu­ments in nearly every one of these pieces, no mat­ter when they were writ­ten, are con­tra­dicted by the way the vast major­ity of Amer­i­cans live and by the polit­i­cal and eco­nomic struc­tures that deter­mine that lifestyle. Sec­ond, the fun­da­men­tal envi­ron­men­tal­ist argu­ments — the fun­da­men­tal per­cep­tions — are unchang­ing over time; only the details vary. We are still catch­ing up to Thoreau, still com­ing to terms with the out­rage George Perkins Marsh expressed in 1864, his wor­ries about “cli­matic excess” and our “rest­less love of change.” Third, writ­ers in every gen­er­a­tion take a crack at find­ing the crys­talline argu­ment that will induce an epiphany in skep­ti­cal read­ers — for noth­ing less than an epiphany will do to per­suade them to change the way they go about liv­ing. Yet every gen­er­a­tion fails, in part because skep­ti­cal read­ers so sel­dom pick up this kind of writ­ing or sub­mit to its evidence.

Her con­clu­sion is also worth not­ing. She reaches for Kafka (There is infi­nite hope, but not for us.) and writes regret­fully: I would say some­thing dif­fer­ent if I could. I have every faith in nature’s recu­per­a­tive powers.…What I doubt is our abil­ity, as a species, to see and, hav­ing seen, to con­tinue to pay attention.

How To Succeed In Business Without Putting People Last

At some point in your surf­ing escapades you begin to grasp that the pro­found impact of the inter­net on learn­ing is not its vast stores of con­tent, but its abil­ity to sup­port the var­i­ous facets of social learn­ing. You begin to appre­ci­ate that knowl­edge is not just a lump of some­thing that is passed on via var­i­ous ped­a­gog­i­cal tac­tics, and your atten­tion begins to shift from the con­tent of a sub­ject to the learn­ing activ­i­ties and human inter­ven­tions around which that con­tent is sit­u­ated. John Seely Brown iden­ti­fies this as a shift from “learn­ing about” to “learn­ing to be.” And “learn­ing to be” calls for inter­per­sonal skills not eas­ily acquired by text­book learn­ing. It’s in this con­text I found myself read­ing back issues of In Char­ac­ter, which exam­ines virtues within our com­mu­ni­ties our fam­i­lies and our­selves. The cur­rent issue delves into com­pas­sion; this obser­va­tion from Howard Behar who empha­sizes com­pas­sion as a vital com­po­nent of acquir­ing per­sonal lead­er­ship skills caught my attention:

Peo­ple are not assets. Car­ing isn’t just about admir­ing the charis­matic lead­ers, the peo­ple that every­body likes, or the in crowd. This is the big car­ing we do that shows we “care, like we really mean it.” It’s about words and actions that every­body sees and rec­og­nizes. There’s an old adage that says, “Peo­ple don’t care how much you know, they want to know how much you care.”

Memories, Emotion and the Nose

Natalie Ang­ier reports from the Inter­na­tional Sym­po­sium on Olfac­tion and Taste held in San Fran­cisco, includ­ing this insight into how smells, feel­ings and mem­o­ries become so eas­ily and inti­mately entan­gled: “With a phone num­ber, if you get a new one, a week later you may have for­got­ten the old one,” Dr. Herz said. “With smells, it’s the other way around. The first asso­ci­a­tion is bet­ter than the second.”

Making Decisions Tires Your Brain

Mar­ket­ing research involv­ing mak­ing choices reveals the brain as a mus­cle: when depleted it comes less effec­tive. Mak­ing choices exhausts what is known as exec­u­tive resources, and “down­stream” deci­sions are affected adversely when we are forced to choose with a fatigued brain. Not only does this explain why I always pick plain yogurt in the refrig­er­a­tor isle, but sug­gests that if we’ve just spent lots of time focus­ing on a par­tic­u­lar task, exer­cis­ing self-control or even if we’ve just made lots of seem­ingly minor choices, then we prob­a­bly shouldn’t try to make a major decision.

Don’t Share — Build

Vic­tor New­man on the futil­ity of every­one shar­ing every­thing in an orga­ni­za­tion: The first prob­lem is the implicit eco­nomic par­a­digm peo­ple apply to ideas and knowl­edge: if every­thing is shared, it will be per­ceived to have lit­tle or no value. Sec­ond, you can spend as much time inter­pret­ing shared things of low value as high. Third, peo­ple will only share with those whom they respect and from whom they can expect a return or who share the same prob­lem of pre­serv­ing or rein­vent­ing iden­tity. These peo­ple don’t always work in the same orga­ni­za­tion. And fourth, not every­one is either pre-disposed or equipped to cre­ate (leave alone share) knowledge.

How To Write With Style

“Pity the read­ers,” advises Kurt Von­negut, whom he calls “imper­fect artists,” strug­gling to mas­ter the dif­fi­cult task of mak­ing sense of thou­sands of scrib­bles on the page. This is my favourite bit advice from Kurt Vonnegut’s “How to Write With Style” (orig­i­nally pub­lished in Palm Sun­day, 1981) that remains rel­e­vant in the net­worked age: “Our audi­ence requires us to be sym­pa­thetic and patient read­ers, ever will­ing to sim­plify and clar­ify — whereas we would rather soar high above the crowd, singing like nightin­gales. This is the bad news.” The good news? We can write about what­ever we please.

The Weird Science of Stock Photography

Adver­tis­ing decon­structed: Stock pho­tog­ra­phy sup­pli­ers must be able to guess which abstract con­cepts clients want to illus­trate, and then have pho­tos and video on hand that res­onates. So,what can we glean from the ubiq­ui­tous “Every­where Girl” and mid-ocean oil rig in a storm?

Shortening the Tail of Scientific Expertise?

Is the web nar­row­ing sci­en­tists’ exper­tise? Soci­ol­o­gist James Evans’ work iden­ti­fies that as more jour­nals become avail­able online, dra­mat­i­cally fewer arti­cles are being cited in the research papers within them. “Rather than mea­sur­ing the length of the tail, it seems that mod­ern sci­ence is actu­ally focus­ing on a tiny bit of it.” The rea­sons for this phe­nom­e­non are unclear, but he does sug­gest that online data­bases make it less likely now than in the past for researchers to inte­grate serendip­i­tous gems of dis­cov­er­ies into their research. Per­haps prov­ing the old adage that, an “expert is some­one who knows more and more about less and less until, even­tu­ally, he knows every­thing about nothing.”
