Undoubtedly, one of the most transcendental discoveries that humanity has had, is that of electric light. It was Thomas Edison who earned the title of inventor of this element so important in our daily lives, however, this discovery does not belong to him alone, since to reach this achievement he had to review the progress of other researchers who had ventured into this field. In spite of everything, Thomas Edison was the first to make a light bulb last more than 40 hours on, without explosions or anything like that.
In short, this discovery deserved a big "Eureka" from Edison, no more candles and goodbye to gas lamps (figuratively speaking, of course).

Johannes Gutenberg is credited with having invented a new way of capturing writings and images, "The printing press" transformed the way of disseminating information and knowledge, it was a very effective tool to reproduce and replicate texts and illustrations faster (still is) far surpassing handwriting, however, our inventor Johannes died in debt and poor, this great "Eureka" consumed him a lot of time and resources, so much! That he had to resort to lenders several times, but in the end he ended up ruined and his project was completed by someone else, I imagine that his disappointment was very great, since he died soon after, a real shame.

The creation of these engines marked a before and after in what we know as a means of transportation, the Italians Felice Matteucci and Eugenio Barsanti were the pioneers of this machinery. Like everything, at the beginning it had its mistakes, but after making some improvements it became a key element for the creation of automobiles, replacing the steam engines that existed at the time.
Trains for example, use this type of engine, but there were also cars with steam engines that were popular in the early twentieth century, however, its impact was seriously affected with the emergence of its rival "the internal combustion engine" to the point of being considered obsolete and outdated.

This device has become an almost indispensable object for us human beings, today, who does not own a Telephone? Even children know how to handle this technology and find it very attractive. However, who was the brilliant mind that came up with this great discovery?
"Antonio Meucci" was the genius behind this Finding, when he invented his prototype in 1854. Who would have thought that the telephone would evolve so much and become the device we know today, with so many functions and uses.
The creation of the telephone was a giant step in the evolution of technology and means of communication. Realistically, today, this advancement continues to grow more and more, where a telephone is: a camera, a recorder, a radio, an alarm...

Probably, if Meucci had not invented it, someone else would have done it, in fact there were several disputes over this title, since shortly after Meucci created the telephone, another researcher invented a very similar one. It is natural for this to happen, as knowledge and technology go hand in hand and both are constantly growing. Who knows what telephones will be like in 50 years, or what important discoveries are yet to be made, I just hope that these advances do not end up destroying us...

Well, as I said before, there are many "Eureka" in our history, but for me, these were the most relevant. I hope you liked my little summary, thanks for your attention, thanks for your support, see you in a next installment! 👋🏼

¡Hola amigos! Aquí estoy de nuevo, dispuesta a participar en la palabra de esta semana. Así que he decidido presentar un breve resumen de los mayores "Eureka" de la historia, según mi perspectiva. Son muchos los descubrimientos que han salido a la luz a lo largo de los años y como saben "Eureka" significa "Descubrir". Es una expresión que la gente utiliza cuando están alegres de haber encontrado un hallazgo importante o significativo.

Esta palabra surgió gracias al matemático Arquímedes de Siracusa, a quien se le encomendó la tarea de verificar si la corona del rey Hierón II era de oro puro o si tenía otros minerales mezclados en su constitución.

Este investigador se puso manos a la obra y después de meditarlo, decidió hacer un experimento en su bañera, donde sumergió la corona en agua y finalmente encontró la respuesta a su pregunta; efectivamente, la corona del rey era de oro puro.
Estaba tan contento que no le importó salir desnudo a la calle y gritar ¡Eureka! Eureka! que quiere decir "lo he descubierto" y así fue como esta expresión quedó bautizada con este significado.

En tal sentido, hice un breve recorrido por la historia para encontrar los "Eureka" más importantes y esto fue lo que conseguí:

1- El descubrimiento de la luz eléctrica

---

2- La creación de la imprenta

---

3- Los motores de combustión interna

---

4- El teléfono:
