Why does a straw look bent in water, a violin ring in a hall, and a siren change pitch as it passes?
Waves, and the same nine ideas explain all of them. Light, sound and a ripple on a pond obey one rulebook.
The story starts in 1801, when Thomas Young shone light through two narrow slits and saw stripes of light and dark. Only waves can cancel each other like that, and that settled the argument about light for a century. Polarization later told us light waves wiggle sideways, which sound waves in air do not.
Pick any card and you will find it again in music, radio or a camera lens. Which one do you meet every day without noticing?

Alfred WEGENER, el meteorólogo que revolucionó la geología.

Today Nov 1. #OTD in 1880 meteorologist Alfred Wegener was born. During his lifetime was known for research in meteorology and as a polar pioneer. Today known as originator of the continental drift hypothesis- suggesting that the continents are slowly drifting around the Earth.

Acuarela de las columnas romanas de la Alameda de Hércules, en Sevilla. Culminando las columnas de granito, capiteles y estatuas renacentistas (Hércules y Julio César).
La Alameda es el primer parque público de Europa (siglo XVI).

Eminent German chemist Adolf van Baeyer born #OTD in 1835 first synthesized indigo dye and the pH indicator phenolphthalein in addition to other discoveries. He also lends his name to the Baeyer-Villiger reaction for oxidation of ketones to esters and was awarded the 1905 Nobel Prize in Chemistry for his theories on ring strain. The German Chemical Society recognizes outstanding research in organic chemistry with an award in his name.

En la mañana del 1 de noviembre de 1755 tuvo lugar el conocido como terremoto de Lisboa (se estima que de magnitud cercana a 9), con epicentro en el Atlántico, a unos 200 km al SO del cabo de San Vicente. Siguió un gran tsunami que azotó la costa de Huelva y de Cádiz.

🩺 El 01/11/1848 abrió sus puertas en Boston (Massachusetts) la New England Female Medical College, conocida inicialmente como Boston Female Medical School, considerada la primera escuela de medicina para mujeres del mundo.
Fue fundada por el médico Samuel Gregory, defensor de que las mujeres pudieran ejercer la medicina, especialmente en la atención a otras mujeres y a los niños.
La iniciativa tenía un origen curioso: Gregory consideraba que la atención de los partos por médicos varones era "antinatural" y defendía que las mujeres debían poder atender a otras mujeres. La escuela comenzó con apenas 12 alumnas y dos profesores.
En 1851 cambió su nombre por el de New England Female Medical College y, en 1864, se graduó allí Rebecca Lee Crumpler, considerada la primera mujer afroamericana en obtener el título de Medicina en Estados Unidos.
Finalmente, en 1873-1874, la institución se integró en la Escuela de Medicina de la Universidad de Boston, contribuyendo a abrir las puertas de la formación médica universitaria a las mujeres.
Un pequeño grupo de 12 mujeres comenzó a cambiar la historia de la medicina.

La fenolftaleína, el indicador de pH más célebre.
Phenolphthalein was synthesized in by Adolf Von Baeyer 🇩🇪in 1871 by reacting phthalic anhydride, phenol, H2SO4 and ZnCl2.
Since 1999 it was banned by FDA from the over-the-counter laxatives. #orgchem #chemistry #analyticalchemistry

Today is Oct 31. #OTD in 1815 mathematician Karl Weierstrass was born. He formalized the definition of the continuity of a function and complex analysis, proved the intermediate value theorem and the Bolzano–Weierstrass theorem, and used the latter to study continuous functions.
