WILHELM CONRAD RONTGEN

 


Wilhelm Conrad Rontgen was a German physicist and professor of physics at Wurzburg Public University, Bavaria. On November 8, 1895, while testing in his laboratory whether cathode rays could pass through the glass, he produced and detected high-energy electromagnetic radiation with a wavelength shorter than that of ultraviolet rays and longer than that of gamma rays. Rontgen took radiation of his wife's hand, which demonstrated the bones of her hand and implied a medical use for the discovery. Mrs Roentgen exclaimed, "I have seen my death." After 7 weeks of study of their properties, of this new type of radiation able to go through screens of notable thickness, he reported about these rays in December 1895. These are now known as X-rays or Rontgen rays. This achievement earned him the first Nobel Prize in Physics in 1901. A very radioactive element 111, roentgenium, with multiple unstable isotopes, is named after him. Rontgen was born on 27 March 1845 in Lennep, Rhine Province, Germany. He died of cancer on 10 February 1923 at the age of 77.

Phoenix Settlement and Tolstoy Farm

  Phoenix Settlement   Tolstoy Farm   Mohanchand Karamchand Gandhi founded two ashrams for community living in South Africa. The Phoenix Settlement was the first ashram-like settlement established near Durban, KwaZulu-Natal in 1904.   This was the home for Gandhi and his family from its founding until his return to India on 9 January 1915.  Tolstoy Farm, the second ashram in South Africa, was  initiated and organized  in Johannesburg in 1910 during his South African Movement.  It  was meant for training and preparing people for non-violent satyagraha and served  f rom 1910 to 1913  as the headquarters for campaigning satyagraha against discrimination against Indians in Transvaal, where it was located. Hermann Kallenbach, a Gandhian supporter, allowed Gandhi and seventy to eighty others to live there as long as their local movement was in effect.   Kallenbach  suggested the name for the community, which soon const...

BLOODY OR RED SUNDAY OF RUSSIAN REVOLUTION

Image
  By 1905, the aging Russian autocracy was in terminal decline. Strikes, unrest, and mutiny sprang up across the vast Russian landscape where, for centuries, people had been told that the Tsar was a saintly father figure; inviolable, all-powerful, and divinely appointed. Demonstrations led by Father Georgy Gapon in St. Petersburg on 22 January 1905 helped to shatter this illusion.  Fr. Gapon was a charismatic speaker and effective organizer who took an interest in the working  and lower classes  of the Russian cities.  Tsarist soldiers opened fire on protesters, killing 140 to 240 people and injuring 33 as per official figures. The crowd had been pro-Tsar, carrying pictures and banners of Tsar Nicholas II, and only wished to present a petition to him  calling for reforms such as limitations on state officials' power, improvements to working conditions and hours, and the introduction of a national . This Bloody Sunday or Red Sunday with a series of events sp...
