  • UNESCO Supports IYL in 2015
    UNESCO Executive Board supports International Year of Light in 2015 PARIS and MULHOUSE, FRANCE ACCRA, GHANA 23 October 2012 The European and African Physical Societies, on behalf of a global partnership of over 40 scientific societies, academies and other institutions, in collaboration with the UNESCO International Basic Sciences Programme (IBSP), are delighted to announce that the UNESCO Executive Board has enthusiastically supported the proposal to declare an International Year of Light in 2015. Light is at the origin of all life, it plays a central role in human activities, and has revolutionized society through medicine and communications, entertainment and culture. Industries based on light are major economic drivers; they create jobs, and provide solutions to global challenges in energy, education, agriculture and health. Light is also important to our appreciation of art, and optical technologies are essential in understanding and preserving cultural heritage. As light becomes a key cross-cutting discipline of science in the 21st century, it is essential that its importance is fully appreciated. It is equally vital that the brightest young minds from all areas of the world continue to be attracted to careers in this field. An International Year of Light will raise public awareness of this essential theme, and thus support the missions and priorities of UNESCO in building capacity in education, science and technology for poverty eradication, responding to critical global social challenges, promoting universal access to information, and safeguarding culture. The study of light is accessible to all ages and all cultures; light is a tremendous subject to motivate education at all levels.

Desde que nos conhecemos, há quase trinta anos, Ubiratan, o ‘pai da etnomatemática,’ tem estimulado a minha prática de educador e investigador e encorajado as minhas reflexões sobre a história da matemática, educação matemática e diversidade cultural. Também tem estimulado o trabalho de pesquisa de colegas meus como Abdulcarimo Ismael, Marcos Cherinda, Daniel Soares, ... Para Ubiratan um grande obrigado, ‘kanimambo,’ de Moçambique! Ubiratan em África Ubiratan participou activamente, em 1976, em Marrocos, no primeiro Congresso Pan-Africano dos Matemáticos, durante o qual se fundou a União Matemática Africana (UMA). Durante muitos anos Ubiratan foi membro do conselho editorial da revista Afrika Mathematika , publicada pela UMA. Em Março de 1978 Ubiratan tomou parte na conferência Desenvolver a Matemática nos Países do Terceiro Mundo , realizada em Khartoum (Sudão), onde apresentou o tema Matemática adequada para os países do Terceiro Mundo: Considerações e Estratégias (El Tom, 1979, 33-46). No mesmo ano, Ubiratan visitou Moçambique, integrado numa missão da UNESCO. E foi no contexto do projecto Mali-1 da UNESCO que se evidenciou o forte envolvimento e engajamento exemplar do Ubiratan com a formação de matemáticos africanos.

  • The Essays in This VISIONS Series, the Kwame Nkrumah Legacy
    The essays in this VISIONS series, The Kwame NKrumah Legacy Project, are the work of individuals who believe that the Unitary Vision espoused and promoted by Ghana's first President, Dr. Kwame Nkrumah, are the essence of Ghana as Nation, and what Ghana (and Africa) can be. These individuals recognize that the international stature and significance of Dr. Nkrumah are completely secure, a point found in many of the essays. However, within Ghana itself, some people do not have reliable information about the Founder of Ghana, Dr. Nkrumah, due to the wanton destruction of heritage records of all sorts and massive misinformation after the CIA-sponsored coup d'état that toppled Nkrumah's CPP at the hands of the Dr. Kofi Busia directed NLM and NLC military regime, in 1966. These essays are an attempt to provide more objective Ghana-centered information about all those records. Some of the essays may have been previously published on other platforms/media. Further, these essays are not the work of reporters and so, readers may find some errors in grammar, diction, spelling. For a Ghana-centered publication where English is not native, we do not fret those imperfections. We believe more in substance, in context, and in the development of the masses and their resources for their own benefit right here on the land, on earth, as Dr. Nkrumah envisioned through his many publications, speeches, and the numerous institutions and physical infrastructure he bequeathed Ghana. Thanks for your interest in VISIONS/The Kwame Nkrumah Legacy Project. Long Live Kwame Nkrumah's Ghana! (In This Volume): Date Comment No Title Name of Author Published Dr.

At a press American Association of Physicists in Medicine conference held at the National Press Building in Washington, American Astronomical Society D.C. in March, APS President D. Allan Bromley joined with American Chemical Society other scientific society presidents in calling on Congress and American Geological Institute the Clinton Administration “to renew the nation’s historical American Geophysical Union commitment to scientific research and education.” Bromley and American Chemical Society President, Paul Anderson American Institute of Biological Sciences amplified the rationale in a nation-wide 15 minute C-Span American Institute of Physics interview. It is unusual for such a large number of scientific American Institute of Professional Geologists organizations, representing a cross section of scientific and American Mathematical Society engineering disciplines and about 1.5 million members, to APS President, D.
