Depuis l'Antiquité, l'Humain a tenté de se déplacer sous l'eau. Pas facile, car notre espèce a besoin d'air pour vivre. On a d'abord utilisé des cloches de plongée, puis des engins amphibies… mais le premier véritable sous-marin a été créé par l'Américain, David Bushnell en 1776. Écoute ce nouvel épisode du podcast pour les enfants « Qui a inventé ? » pour découvrir l'histoire de ces incroyables navires…David Bushnell invente le premier sous-marinNous sommes en 1776, aux États-Unis… À cette époque, les habitants de la côte est du pays combattent pour leur indépendance. Ils se révoltent contre les Anglais qui occupent ce territoire. David Bushnell est un fils de fermier, bricoleur et ingénieux, qui a fait des études scientifiques. Avec son frère Ezra, il a une idée pour combattre les Anglais qui ont imposé un blocus sur les ports américains. Quelque temps plus tard, les frères présentent aux responsables militaires de l'époque leur sous-marin, baptisé Turtle (tortue, en anglais). Pour la première fois, l'humain se déplace dans un engin sous-marin, grâce à un système de ballasts.Comment fonctionnent les ballasts dans un sous-marin moderne ?Les ballasts sont des réservoirs qui peuvent se remplir d'eau ou d'air selon qu'on veut s'enfoncer ou remonter à la surface. Pour comprendre, il faut savoir qu'un sous-marin dispose de 2 coques :• 1 coque intérieure, qui abrite l'équipage et les machines. Elle est très épaisse pour résister à l'immense pression qui s'exerce quand on s'enfonce sous l'eau.• 1 coque extérieure, plus fine, avec une forme permettant de bien avancer dans l'eau (on dit qu'elle est hydrodynamique). Entre ces 2 coques, on trouve des réservoirs, à l'avant et à l'arrière du sous-marin : les ballasts. Lorsque ces “poches” sont remplies d'air, cela permet de rester à la surface. Quand on veut plonger, on fait entrer de l'eau dans les ballasts ! Le sous-marin descend. À l'inverse, quand on veut regagner la surface, on vide l'eau des ballasts grâce à de l'air comprimé. Avec cet air, le sous-marin remonte.Ça avance comment, un sous-marin ?Une hélice, qui tourne grâce à un moteur électrique, fait avancer les sous-marins (jusqu'à 60 km/h en plongée) !Comment fait-on pour respirer dans un sous-marin ?Des machines, qui produisent de l'oxygène et recyclent l'air intérieur, permettent aux équipages des sous-marins de respirer. Certains peuvent rester plusieurs mois sous l'eau sans remonter à la surface…

Submarines are the silent hunters of the deep. From the large nuclear-powered boats of today's navies, to the German U-Boats of the First and Second World Wars, these machines hidden beneath the waves can change the course of history. In the United States, the first submersible was the Turtle with an egg-shaped hull designed by David Bushnell. This hand-powered submarine was used in a failed attempt to sink the British ship HMS Eagle in New York Harbor in 1776. Nearly one hundred years later the HL Hunley, a submarine built by the Confederate States of America, would become the first to sink an enemy vessel during the American Civil War.

Bajo el agua: la invención del submarino

Cuenta una leyenda que, allá por el siglo IV a.C., Alejandro Magno encargó que le fabricasen un barril de vidrio para sumergirse en el mar y contemplar la fauna subacuática. No sabemos si es cierto, pero, de serlo, la idea de meterse bajo el agua con un artefacto hecho por el hombre lleva dando vueltas más de dos mil años. Pero no es una idea fácil de materializar ya que el agua es un medio muy hostil. El ser humano aprendió pronto a dominar las olas y después los vientos, pero manteniéndose siempre en la superficie. No fue hasta finales del siglo XVI cuando un matemático inglés llamado William Bourne se planteó en serio eso de diseñar una máquina submarina. No lo consiguió porque la empresa superaba con mucho los medios tecnológicos de la época, pero ahí quedó el reto hasta que, muchos años más tarde, primero un holandés llamado Cornelius Drebbel y un estadounidense llamado David Bushnell crearon dos vehículos sumergibles de madera. El primero se propulsaba con remos, el segundo gracias a una manivela accionada con las manos. Los de Drebbel y Bushnell fueron los primeros submarinos que podían moverse a su antojo bajo el agua, aunque no durante mucho tiempo ni navegando muy profundo. En la guerra civil de Estados Unidos los ingenieros de la Confederación desarrollaron un sumergible con el que trataron de romper el bloqueo al que Unión sometía a los puertos del sur. La embarcación consiguió hundir una balandra en la bahía de Charleston, luego se hundió porque a los tripulantes se les acabó el oxígeno. Los inventores del siglo XIX concluyeron que lo mejor era hacer estas máquinas de metal para ir más al fondo y dotarlas de plantas motrices que les permitiesen navegar de forma autónoma. En el fondo del mar no hay viento, pero si corrientes lo suficientemente fuertes como para que la propulsión humana no baste. Además, si se quiere hacer navegación submarina en serio de nada sirve limitarse a ríos, lagos y puertos. Eso condujo a una carrera entre ingenieros de todo el mundo para crear el primer submarino que prescindiese de la propulsión humana. En 1863 dos franceses crearon el Plongeur (buceador), que equipaba un sistema de aire comprimido. Un año más tarde un inventor español llamado Narcís Monturiol inventó el primer submarino con motor de combustión. Podía sumergirse 30 metros y permanecer bajo el agua un par de horas. El de Monturiol, bautizado por su inventor como Ictíneo, fue, de hecho, el primer submarino moderno. Otro español, el ingeniero de la Armada Isaac Peral, creo unos años después el primer submarino militar, pero tanto Monturiol como Peral eran hombres adelantados a su tiempo por lo que sus inventos no tuvieron la aceptación que ellos esperaban. La era de los submarinos no llegaría hasta principios del siglo XX, cuando una serie de desarrollos técnicos y el estallido de la primera guerra mundial hicieron del arma submarina un activo importantísimo para cualquier ejército. Los alemanes lo emplearon de forma muy intensa desatando una campaña de guerra submarina sin cuartel que tuvo como efecto inmediato la entrada de Estados Unidos en la guerra cuando un U-Boot de la marina imperial alemana hundió al sur de Irlanda el Lusitania, un paquebote británico en el que viajaban muchos pasajeros estadounidenses. Alemania volvió a pertrecharse de submarinos para la segunda guerra mundial, submarinos mucho más avanzados que protagonizaron la batalla del Atlántico. Para entonces el submarino ya había alcanzado su mayoría de edad. Tras la guerra las potencias vencedoras siguieron perfeccionándolos hasta conseguir embarcaciones de gran tamaño y mucha complejidad técnica capaces de librar una batalla ellos solos y de dar comienzo incluso a una guerra nuclear.

O mar sempre foi um grande mistério para a humanidade. A vontade de quebrar as barreiras físicas do corpo humano e conseguir resistir por mais tempo e ir mais fundo no oceano, sempre existiu. O primeiro registro de um submarino (se é que dá pra chamarmos assim), é da Grécia antiga. Aristóteles relatou que algumas pessoas usavam um equipamento chamado Lebeta, que permitia as pessoas irem mais fundo e ficarem mais tempo de baixo d'água. DaVinci, claro, foi outro a se dedicar à criação de um submarino. O equipamento desenvolvido por ele "Trata-se de um sistema de mergulhador com dois canos feitos de pele animal pelos quais o ar desce e sobe através de uma bomba manobrada da terra firme. Seria utilizado para ataques surpresa debaixo d água. Ele chegou também a desenhar um submarino acionado pela força humana e movido através de engrenagens", conta o historiador Luca Paolo. Já no século XVII, o holandês Cornelis Drebbel construiu o primeiro submarino que funcionava. Ele foi financiado por Jaime I, rei da Inglaterra. Movido a energia humana, ele era uma espécie de dois barcos com 4 remos, que usava bexiga de porco para submergir e emergir. Conseguia submergir por volta de 4 a 5 metros. Durante a Guerra de Independência dos EUA, o Turtle nascia. O Turtle era um submarino desenvolvido por David Bushnell e era totalmente individual, cabendo apenas uma pessoa. Nunca foi encontrado uma prova de que de fato ele existiu, mas de acordo com relatos escritos, ele era utilizado para colocar bombas nos navios ingleses. Os submarinos iriam se tornar uma ferramenta de guerra mesmo na Primeira Guerra Mundial, quando a Alemanha irá focar no desenvolvimento desse tipo de embarcação para atacar justamente a Marinha Inglesa, que era conhecida como a melhor marinha do mundo. Os submarinos alemães serão, por muito tempo, sinônimo de submarino de qualidade. Mas com o fim das duas guerras mundiais e um boom na tecnologia dos submarinos, a Guerra Fria chegou. Juntamente com a luta indireta entre EUA e URSS, a energia nuclear aparecia e mudava completamente as possibilidades dos submarinos. Em 1954, a marinha americana utilizou o primeiro submarino movido a energia nuclear. Seu nome era USS Nautilus (hoje é um navio museu). Esses submarinos podem ficar até 6 meses debaixo d'água e podem lançar mísseis nucleares submersos.

As History Impossible reaches its two year mark and the episodes get longer and longer, I figured that now was the time to do something different, namely to add a new show to the History Impossible family, as I've been calling it: Infinitesimal Impossibilities. These are stories that are simply too small--bite-sized, if you will--in comparison to the epic stories that have come to characterize History Impossible and to help me out with this, I've brought on my amazing Pop Quiz co-host (and victim) Molly Pan to help keep us on course.   And speaking of staying on course, this first Infinitesimal Impossibility is indeed about a device that had a lot of a trouble staying on course without an amazing pilot behind it (and an ingenious design for its time). That would be the American Turtle, the first combat submarine ever deployed in the world. What makes this story so seemingly impossible has everything to do with when this device operated, namely in the lack of appropriate technology and the insane ingenuity and clever know-how by its creator, David Bushnell.   So sit back and enjoy this first of hopefully many installments of Infinitesimal Impossibilities. As always, many thanks to Molly Pan for the artwork AND co-hosting duties.   History Impossible has been made possible by the following generous supporters on Patreon and PayPal: Elias Borota Matthew Dakus Gavin Edwards Peter Hauck Devin Hreha Mike Kalnins Benjamin Lee Tyler Livingston  Jose Martinez Mike Mayleben Judy McCoid Kostas Moros Molly Pan Jake Petersen John Pisano Edmund Plamowski Brian Pritzl PJ Rader Mark Reed Sam Emily Schmidt Ricky Worthey Steve Uhler

Su capacidad para generar empatía y su habilidad para mantener un balance entre su vida laboral y personal. 18:13 Recomienda ampliamente ver “La historia sin fin” (Wolfgang Petersen, 1984) 19:35 Considera que una compra que le ha cambiado la vida ha sido comprar una máquina para hacer agua con gas en su casa. 20:49 Si tuviera la oportunidad de decirle algo al mundo sería que no dejen de soñar y crear. 21:22 Valentina considera que su hábito absurdo es seguir consumiendo chicles de nicotina a pesar de haber dejado de fumar hace más de 8 años. 22:21 Considera que una opinión errónea que la gente tiene de ella es que es muy desorganizada u olvidadiza. 24:17 ¿Cómo es la cultura de su empresa? 26:18 Si pudiera darle un consejo a su versión joven sería que no intente cambiar las cosas tan rápidamente, que intente entender todo y no creer que se las sabe todas. 27:28 Al pensar en éxito, Valentina piensa en el balance entre lo personal, profesional, familiar, espiritual y académica. 28:51 Valentina considera que su fracaso favorito fue que la hayan rechazado la entrada a la carrera de periodismo, pues gracias a ello estudió un curso de business management que le dio una perspectiva que no había pensado antes. 30:32 Por igual considera que una de sus mejores decisiones es siempre estar estudiando algo. 31:53 Al entrevistar a alguien se fija en cómo la saluda y que sea una persona curiosa. 35:15 A los jóvenes recién egresados les diría que no tengan miedo y que no crean que no están preparados para algo. 38:20 Daniel Marcos menciona que el escalamiento es mental antes que físico a lo que Valentina responde que, en ocasiones, es necesario “alejarse” de la situación para verlo desde otra perspectiva. 39:27 Cómo último consejo nos dice que nada es permanente y que después de la tormenta siempre viene la calma. 40:38 Despedida y agradecimientos

Few people know about America's attempt at sinking the British fleet by deploying the world's first submarine, The Turtle. Its creator, David Bushnell, should have been lauded as one of the finest minds of that or any era. Instead, he ended up largely forgotten.
