Thermos Day + Día del Termo [Eng+Spa]

Monday, start of the week. This February 26 we have been a little low on health at home, the weather was a little cool, and we may have caught a bit of a cold. We had pending repairs at home, but we couldn't attend to them, we will have to do the work tomorrow. Outside these minor things, there is nothing new to tell about my #life. So I can comment on the topic that gives me the title of this post.

I know that there are all kinds of celebrations and anniversaries of #History, there are even special days to celebrate peculiar artifacts. But, I didn't know that there was a day to celebrate containers capable of maintaining the temperature level of the liquids inside. However, when I saw the list, I found out that today is 'Thermos Day'.

Lunes, inicio de semana. Este 26 de febrero hemos estado un poco bajos de salud en casa, el clima estaba un poco fresco y puede que nos resfriáramos un poco. Teníamos pendientes reparaciones en casa, pero no logramos atenderlas, tocará hacer el trabajo mañana. Fuera de estas cosas menores, no hay nada nuevo que contar de mi #vida. Así que puedo pasar a comentar sobre el tema que me da el título de este post.

Yo sé que hay toda clase de celebraciones y efemérides de la #Historia, incluso hay días especiales para celebrar artefactos peculiares. Pero, no sabía que existía un día para celebrar los contenedores capaces de conservar el nivel de temperatura de los líquidos en su interior. Sin embargo, al ver el listado, me enteré de que hoy es el ‘Día del Termo’.

A #thermos is a double-layer container (separated by a vacuum space) that provides some resistance to the thermal exchange of a liquid with respect to its environment, passively. Well, that sounds very technical, like a #science topic, but when reviewing the history of this invention, I found that it was initially a laboratory gadget. The closest thing to what we know today as thermoses was the product of the research of James Dewar, a Scottish physicist and chemist.

Here comes another curiosity, the name we give to this thing today, thermos, is more of a later designation. This container was originally called a 'Dewar flask' or 'Dewar bottle'.

In 1892, Dewar was researching the specific heat of palladium, as part of his work in physics, specifically cryogenics. Being a matter in which he was quite innovative, he had to make use of the best equipment and gadgets that he could have available, as a Professor at the University of Cambridge. But, he encountered new and peculiar challenges, so he also created some instruments of his own, among these, he designed a glass container, which consisted of two layers of glass separated by a vacuum. That proved to be quite useful in his investigation.

Un #termo es un contenedor de doble capa (separadas por un espacio en vacío) que brinda cierta resistencia al intercambio térmico de un líquido con respecto a su ambiente, de manera pasiva. Bien, eso suena muy técnico, como un tema de #ciencia, pero es que al revisar la historia de este invento, me encontró que inicialmente era un artilugio de laboratorio. Lo más cercano a lo que hoy en día conocemos como termos, fue producto de la investigación de James Dewar, físico y químico escocés.

Acá viene otra curiosidad, el nombre que le damos a esta cosa hoy en día, termo, es más bien una designación posterior. Este contenedor se llamaba en un inicio ‘frasco de Dewar’ o ‘Botella de Dewar’. En 1892, Dewar estaba investigando sobre el calor específico del paladio, como parte de sus trabajos en #fisica, específicamente sobre criogenia. Siendo un asunto en que era bastante innovador, le tocó hacer uso de los mejores equipos y artilugios que podía disponer, como Profesor en la Universidad de Cambridge. Pero, se encontró con retos nuevos y peculiares, así que también creó algunos instrumentos propios, entre estos, diseñó un envase de vidrio, que consistía en dos capas de vidrio separadas por un vacío. Eso demostró ser bastante útil en su investigación.

This man gave several interesting contributions in his fields of work, but I want to focus on the thermos, so I must leave it to him and go on to name other people who collaborated so that the object became as we know it today. Among these we have, in 1904, Reinhold Burger and a fellow glassblower (both German), who discovered its commercial application to keep drinks (hot or cold), so they proceeded to work to create their version, patent it, and put it up for sale. These Germans used a word with Greek roots to name their product, and that is where the Thermo was officially born.

After this beginning, Gustav R. Paalen, a Viennese inventor and merchant from the beginning of the 20th century, improved the design on his own, patented them, and also marketed them, but taking his products to both sides of the Atlantic, thus its internationalization began. After this, during the great wars of the 20th century, the times between wars, and domestic use, the thermos became part of common objects in many places. And the essential of its design is still preserved.

Este hombre dio varios aportes interesantes en sus campos de trabajo, pero quiero centrarme en el termo, así que debo dejarlo a él y pasar a nombrar a otras personas que colaboraron para que el objeto llegara a ser como lo conocemos hoy. Entre estos tenemos, en 1904, a Reinhold Burger y un colega soplador de vidrio (ambos alemanes), que descubrieron su aplicación comercial para mantener las bebidas (calientes o frías), por lo que procedieron a trabajar para lograr crear su versión, patentarla, y ponerla en venta. Estos alemanes usaron una palabra de raíz griega para nombrar su producto, y es allí donde oficialmente nace el Termo.

Luego de este inicio, Gustav R. Paalen, un inventor y comerciante vienes de principios del Siglo XX, mejoró el diseño por su cuenta, los patentó, y también los comercializó, pero llevando sus productos a los dos lados del Atlántico, con lo que se dio inicio a su internacionalización. Posterior a esto, durante las grandes guerras del Siglo XX, los tiempos entre guerras, y el uso doméstico, el termo pasó a ser parte de los objetos comunes en muchos lugares. Y aún se conserva lo esencial de su diseño.

Well, as you see, from a laboratory tool, to reaching our kitchens or outdoor excursion tents, the Thermos has come a long and interesting path. I say goodbye now, wishing you that you are well and that we can read again another time.

Bien, tal como vez, desde una herramienta de laboratorio, hasta llegar a nuestras cocinas o tiendas de excursión al aire libre, el Termo ha recorrido un largo e interesante camino. Ya me despido, deseándote que tú estés bien y que nos podamos leer de nuevo en otra oportunidad.
