Xavier Mass\u00f3<\/strong><\/a><\/p>\n

 <\/p>\n

El 22 de febrer del 1923, Albert Einstein<\/strong> arribava a Barcelona. Va romandre sis dies a la ciutat, durant els quals va impartir diverses confer\u00e8ncies per divulgar les seves concepcions f\u00edsiques sobre la relativitat.<\/p>\n

Venia precedit per la seva fama, convidat pel Govern espanyol i la Mancomunitat de Catalunya, passant primer per Barcelona i despr\u00e9s per Madrid. L’any anterior havia estat guardonat amb el Premi Nobel de F\u00edsica, encara que no per la seva aportaci\u00f3 m\u00e9s not\u00f2ria i merit\u00f2ria a la ci\u00e8ncia, la Teoria de la Relativitat, sin\u00f3 pels seus estudis sobre l’efecte fotoel\u00e8ctric. L’Acad\u00e8mia sueca de la ci\u00e8ncia no tenia encara gaire clar aix\u00f2 de l’espai-temps i la relativitat, aix\u00ed que va optar per la cautela i va preferir, per evitar pol\u00e8miques, concedir-li el Nobel per una feina que, encara que important, era marginal en la seva activitat cient\u00edfica. Les seves heterodoxes posicions cient\u00edfiques i la popularitat que havia aconseguit\u00a0 auguraven una recepci\u00f3 multitudin\u00e0ria. I aix\u00ed va ser, per\u00f2 no pas en un primer moment.<\/p>\n

Va arribar acompanyat de la seva segona esposa Ilse a l’estaci\u00f3 de Fran\u00e7a de Barcelona, \u200b\u200bprocedent de Par\u00eds, sense que ning\u00fa no acud\u00eds a rebre’l. Aleshores es va dirigir al domicili d’Esteve Terrades, l’enginyer i matem\u00e0tic que havia gestionat la invitaci\u00f3, que no era a casa seva. Va deixar-hi l\u2019enc\u00e0rrec i es va dirigir a la primera pensi\u00f3 que va trobar: \u201cPensi\u00f3 les quatre nacions<\/em>\u201d; un tuguri. Un cop resolt l’embolic, les autoritats el van allotjar a l’Hotel Col\u00f3n, a la Pla\u00e7a Catalunya.<\/p>\n

Hi ha dues versions sobre la causa d\u2019aquesta rebuda tan anodina. Uns asseguren que Einstein no havia informat ning\u00fa de l’hora de la seva arribada; altres ho atribueixen al proverbial desordre mediterrani. En fi. Contra el que se sol pensar acudint al t\u00f2pic, la veritat \u00e9s que en aquells temps, i encara que des d’una posici\u00f3 certament semiperif\u00e8rica, els cient\u00edfics espanyols, i no menys els catalans, estaven al corrent dels progressos i els debats cient\u00edfics del moment. Tot i aix\u00f2, de les seves confer\u00e8ncies a Barcelona hom podria dir que van tenir un efecte bastant semblant a les que va impartir a Madrid la setmana seg\u00fcent, que Julio Gamba va descriure aix\u00ed al diari \u2018El Sol\u2019: \u201cSens dubte que tots els que \u00e9rem all\u00ed reunits l\u2019admir\u00e0vem molt; per\u00f2 si alg\u00fa ens pregunta per qu\u00e8 l\u2019admir\u00e0vem tant, ens posar\u00e0 en un destret d\u2019all\u00f2 m\u00e9s seri\u00f3s<\/em>\u201d.<\/p>\n

Al sal\u00f3 de sessions de la Diputaci\u00f3 de Barcelona i davant d’unes cent persones, va impartir un curs sobre la teoria de la relativitat en tres sessions: relativitat restringida, relativitat general i problemes actuals, i va pronunciar tamb\u00e9 una quarta confer\u00e8ncia addicional a la Reial Acad\u00e8mia de Ci\u00e8ncies i Arts de Barcelona. Les transcripcions de les seves confer\u00e8ncies es van publicar \u00edntegrament al rotatiu La Vanguardia<\/em>; aix\u00f2 s\u00ed, amb el preceptiu contrapunt de les objeccions de Josep Comas i Sol\u00e0, el f\u00edsic local anti-relativista.<\/p>\n

Els amfitrions i els cicerons d’Einstein durant la seva estada a Barcelona van ser el ja citat Esteve Terrades i Rafel Campalans, enginyer com l’anterior. Amb ells va compartir el 25 de febrer una excursi\u00f3 al Monestir de Poblet, passant per l\u2019Espluga de Francol\u00ed. De tornada a Barcelona, \u200b\u200bi amb alguns convidats m\u00e9s, va tenir lloc un sopar l’enigm\u00e0tic men\u00fa del qual consistia en noms escrits jocosament en llat\u00ed intencionadament macarr\u00f2nic, al\u00b7lusius a cient\u00edfics i fil\u00f2sofs a la manera d’endevinalles, com Cannulae Fizeauniensis<\/em>, Fructus Galilei<\/em>, Homo platonicus secundum, Diogenem cum jure<\/em>, Michellsoniense spirituosibus liquoribus et vectoribus tabacalibus<\/em>\u2026<\/p>\n

Se sap que el sopar va estar ben regat -Einstein no era cap timorat-, per\u00f2 encara que s’ignori si va ser o no per causa dels spirituosibus liquoribus<\/em> -que sempre ajuden a que no llangui la conversa- i els corresponents vectoribus tabacalibus -en aquells temps als matraques, o no se\u2019ls convidava o s\u2019havien d\u2019aguantar- el cert \u00e9s que la cosa va derivar cap a la pol\u00edtica, i va oc\u00f3rrer l\u2019an\u00e8cdota que a continuaci\u00f3 referirem.<\/p>\n

Entengueu que estem parlant d’una tert\u00falia intel\u00b7lectual en el ple sentit il\u00b7lustrat del terme, \u00e9s a dir, protagonitzada per gent que, a la condici\u00f3 de cultes, hi afegien la d’educats. No ens confonguem per tant amb les dels habituals tertulians nostrats, en les quals hi fretura tan la primera com la segona condici\u00f3. En un moment de la tert\u00falia va sorgir la b\u00e8stia negra del moment: l’auge dels nacionalismes a Centroeuropa, molt especialment a Alemanya. Campalans va dir a Einstein que ell era nacionalista i d’esquerres \u2013nacionalista catal\u00e0, se sobreent\u00e9n\u2013. Davant d’aquesta afirmaci\u00f3, Einstein va posar una d’aquelles cares de perplexitat que sabia fer tan b\u00e9 i va replicar en alemany: \u201cDas passt nicht zusamnen<\/em>!\u201d<\/p>\n

O el que \u00e9s el mateix: aquestes dues coses no poden oc\u00f3rrer juntes. Campalans explica que despr\u00e9s va intentar explicar-li els matisos de la seva afirmaci\u00f3 i que Einstein li va respondre: \u201cLlavors aix\u00f2 no \u00e9s nacionalisme, traieu aquesta sinistra paraula del vostre ideari<\/em>\u201d.<\/p>\n

El dia 28 de mar\u00e7 va agafar el tren cap a Madrid. De la seva estada a Barcelona va anotar al seu diari un breu par\u00e0graf i va deixar una p\u00e0gina en blanc, potser per omplir-la m\u00e9s endavant, tot i que mai ho va arribar a fer. L’\u00fanic que hi va anotar va ser el seg\u00fcent:<\/p>\n

22-28 febrer. Estada a Barcelona. Molta fatiga, per\u00f2 gent amable (Terrades, Campalans, Llana, la filla de Tirpitz), can\u00e7ons populars, balls, Refectorium, Ha estat agradable!<\/em><\/p>\n
