Marie Curie una mujer adelantada
Marie Curie, Sklodowska de soltera, además de pasar a la historia por sus descubrimientos, fue una de las mujeres más adelantada a su tiempo. Nació en Varsovia (Polonia), en 1867, estudió Química, Física y Matemáticas. Tímida, humilde económicamente, se volvió anémica y obsesiva con los estudios.
El año 1894 fue clave, Marie conoce a Pierre Curie, el que después sería su marido. Pierre al igual que Marie estaba dedicado en cuerpo y alma a la investigación científica. Los dos empiezan a trabajar juntos en el laboratorio, y al año siguiente Pierre se declara a Marie, casándose el 26 de julio de 1895.
El trabajo del matrimonio Curie pronto alcanzó sus frutos al descubrir en 1898 el polonio. En diciembre del mismo año revelaron la existencia de un segundo elemento químico nuevo al que bautizaron con el nombre de radio, elemento de enorme radiactividad. Tendrían que pasar cuatro años para que los esposos Curie pudieran probar la existencia del polonio y el radio.
En 1902, tras muchas penurias económicas y meses de trabajo, Marie logró, al fin, preparar un decigramo de radio puro, había determinado el peso atómico del nuevo elemento. Los químicos tuvieron que rendirse ante la evidencia de los hechos. A partir de aquel momento el radio existía oficialmente.
Mientras la investigación de la radiactividad progresaba, el matrimonio Curie se iba agotando poco a poco y sin darse cuenta, la intensidad de sus radiaciones sobrepasó todo lo esperado.
Premio Nobel
El último y más maravilloso milagro era que el radio podía convertirse en un aliado del hombre en su lucha contra el cáncer. Tenía pues, una utilidad práctica, y su extracción había dejado de tener un simple interés experimental. Iba a nacer la industria del radio. El 10 de diciembre de 1903 se les otorgó el Premio Nobel de Física, compartido junto a H. Becquerel, por sus descubrimientos relacionados con la radiactividad.
Pasaron otros ocho años de paciente labor antes de que Marie lograra instalar la radiactividad en un lugar para la historia, lugar que Pierre no habría de conocer. En 1906 fallecería su esposo; un mes después, el Consejo de la Facultad de Ciencias otorgó a la viuda de Curie la cátedra que había desempeñado su esposo en la Sorbona. Era la primera vez que se concedía tan alta posición en la enseñanza universitaria de Francia a una mujer. La fama de Marie Curie subió como la espuma, se le concedió el Premio Nobel de Química en el año 1911.
El radio que Marie descubrió, y que tantas vidas ayuda a salvar hoy en día, fue el causante de su muerte. Tantos años respirando el aire viciado de sus emanaciones tuvieron un resultado trágico. Los análisis de sangre posteriores descubrieron que el causante del fallecimiento de Marie había sido el radio.
El 6 de julio de 1934, y sin reconocimientos de ningún estamento social, Madame Curie fue enterrada en el cementerio de Sallanches junto a su esposo. Sólo los parientes, los amigos y los colaboradores de su obra científica asistieron al sepelio.

It is easy to feel like you want to stop trying when you cannot quite seem to come across important information. The funny part, maybe, is there is enough content on the net, but you are still not sure if the sources are trustworthy. No individual has been immune to this because it is just the nature of the online world, unfortunately. The balance of this report will take a look at this important topic in a lot more detail.
The general complexities of women's and men's fashion
Both men and women may feel the pressures of keeping their wardrobe up-to-date and in season, yet men's fashion usually seems a lot less difficult. Of program, for both genders, garments and fashion options can be quite as elaborate, and there are many'stylish'items that could quickly become fashion faux pas - who are able to say they frequently see people walking on in 70s flares? On the other side, men's style has a few staple things that can exist forever - which man is going to keep an eye out of place with a good-quality, tailored suit, for example? Select classic cuts, colours and materials and you'll never seem out-of-place.
Why basic men's style is timeless
The basic man's suit has barely changed for over a hundred years. True, there are several kinds for different situations, however they are all common in their pursuit of a wise, sharp look for the person. The best part about classic style for men is that it is effortlessly stylish simply cool. A well-groomed man will typically look his sharpest in a well-tailored suit, and it is a testament to the style of such clothing. A suit will undoubtedly be worn to work in several professions due to the professional look it offers to the person, instilling a feeling of respect and confidence. Equally a match will be worn to many social situations, like a tuxedo to a black-tie event. This incredible flexibility that allows suits to be used in just about all events is what gives it its classic border and a permanent invest men's fashion.
Modern movements in traditional men's fashion
Whilst classic men's designs can never be changed, it is interesting to observe that changes in men's fashion trends have produced particular basic garments back in fashion. The popularity of vintage clothing, especially, has taken back a wide-variety of classic designs into men's closets, such as that of the dandy guy. 'Dandy'is a term used to reference men who dress yourself in a classic yet luxurious way, placing importance on appearance and acting in a sophisticated method. This pattern for almost'over-the-top'classic style for men is evident from events such as the'Tweed Run', where men and girls of all ages dress yourself in notably Victorian-style outfit and decide to try the streets on vintage cycles - with many of the men sporting impressive mustaches! This really is just one of many types of research presenting the resurgence of such types. Additionally, there are numerous blogs on line which give attention to gentlemanly type - such as'The Dandy Project'and'Dandyism'- as well as complete internet sites such as'The Art of Manliness'specialized in giving articles on classic men's fashion and grooming.
In summary, though certain issues with traditional men's style can be brought back as new trends, the basic outfits that they are derived from will never slip out of fashion.
