His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in investments). Bell being awarded the first U.S. patent for the telephone in 1876. In retrospect, Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions The Speaker marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. In 1888, Alexander Graham Bell became one of the founding members of the National Geographic Society. In Dr. Manish Kothari 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Vice President, Engineering Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Qualcomm India Private Limited Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain.

  • 2020 a Sentimental Journey
    0 1 3 Lifescapes is a writing program created to help people tell their life stories, to provide support and guidance for beginner and experienced writers alike. This year marks our thirteenth year running the program at the Brantford Public Library, and A Sentimental Journey is our thirteenth collection of stories to be published. On behalf of Brantford Public Library and this year’s participants, I would like to thank lead instructor Lorie Lee Steiner and editor Shailyn Harris for their hard work and dedication to bringing this anthology to completion. Creating an anthology during a pandemic has been a truly unprecedented experience for everyone involved. Beyond the stress and uncertainty of facing a global contagion, our writers lost the peer support of regular meetings and access to resources. Still, many persevered with their writing, and it is with considerable pride and triumph that I can share the resulting collection of memories and inspiration with you. I know that many of us will look back at 2020 and remember the hardship, the fear, and the loss. It is more important than ever to remember that we – both individually and as a society – have persevered through hard times before, and we will persevere through these times as well. As you read their stories, be prepared to feel both the nostalgia of youth and the triumph of overcoming past adversity. Perhaps you will remember your own childhood memories of travelling with your family, or marvel at how unexpected encounters with interesting people can change perspective and provide insight … and sometimes, change the course of a life.

    SIR EDMUND WALKER, SERVANT OF CANADA by Barbara' Ruth Marshall B.A., York University, 1969- A Thesis Submitted in Partial Fulfilment of The Requirements for the Degree of Master of Arts in the Department of History We accept this thesis as conforming to the required standard The University of British Columbia June, 1971 In presenting this thesis in partial fulfilment of the requirements for an advanced degree at the University of British Columbia, I agree that the Library shall make it freely available for reference and study. I further agree that permission for extensive copying of this thesis for scholarly purposes may be granted by the Head of my Department or by his representatives. It is understood that copying or publication of this thesis for financial gain shall not be allowed without my written permission. Depa rtment The University of British Columbia Vancouver 8, Canada i ABSTRACT In the laissez-faire system of the late nineteenth century, Sir Edmund Walker, Canadian businessman, saw his life in terms not of his personal gain, but of his service to his country. His Victorian curiosity and ethic of service prompted him to work for Canada in many varied areas from banking, to the arts, to planning a new imperial structure in the Round Table. By World War I, however, this Victorian ethic could no longer survive in the modern world which had evolved. Government also ended laissez-faire by entering fields which business philanthropy had neglected. While most Canadians seemed to recognize Sir Edmund's achievements, after the war they scoffed at his outdated views of service.

Mining for gypsum, or Plaster of Paris, began in Ontario in 1822 by Squire William Holme, first settler in the Paris area. Deposits of gypsum were found along the banks of the river both upstream and downstream of the town. For the first two years of mining, the gypsum was broken up by sledge hammers. In 1824, a race- way was dug to allow easy access to a grinding mill. The gypsum was sold to settlers as fertilizer and course plaster for housing.

  • Uma Das Patentes De Alexander Graham Bell
    UNIVERSIDADE ESTADUAL DE CAMPINAS INSTITUTO DE FÍSICA “GLEB WATAGHIN” F 609 – TÓPICOS DE ENSINO DE FÍSICA I Coordenador: Profº Dr. Jose Joaquín Lunazzi TELEFONE COM DIAPASÃO: UMA DAS PATENTES DE ALEXANDER GRAHAM BELL André Coelho da Silva* Orientação: Profº Dr. Peter Alexander Bleinroth Schulz** 2º semestre de 2009 – Relatório finalizado em 3 de dezembro * [email protected] ** [email protected] 1) RESULTADOS ATINGIDOS Após a coleta dos materiais necessários e a busca por fontes de informação sobre o tema, foram alcançados como resultados uma bem-sucedida realização do experimento do telefone com diapasão e uma discussão da parte histórica envolvida no surgimento do telefone. Ou seja, foi possível, assim como fez originalmente Alexander Graham Bell, transmitir o som de um diapasão através de fios elétricos e ouvi-lo com o auxílio de um alto-falante; e realizar um trabalho sobre a evolução das telecomunicações focado principalmente no telefone e nos protagonistas de seu desenvolvimento. Deve-se ressaltar que, ao menos a priori, não há restrições no que diz respeito ao público-alvo deste trabalho. 2) FOTOS DA EXPERIÊNCIA Seguem logo abaixo as fotos dos materiais utilizados: Figura 1: Diapasão de garfo Figura 2: Bateria de 9 Volts Figura 3: Alto-falante Figura 4: Parte de trás do alto-falante 2 Figura 5: Tipo de fio elétrico usado Figura 6: Recipiente com água e vinagre Com os materiais acima, montamos o experimento: Figura 7: Montagem experimental – as setas azuis indicam que dois fios compõem o fio branco do alto-falante, um deles deve ser ligado ao diapasão e o outro à bateria 3 3) DIFICULDADES ENCONTRADAS Na etapa de coleta de materiais houve certa dificuldade em encontrar um alto-falante que pudesse ser usado, então, o retiramos de uma “caixinha” de som (de computador).
