German-born theoretical physicist; Developer - general theory of relativity

Albert Einstein was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." Albert Einstein was born in Ulm, Germany on March 14, 1879. As a child, Einstein revealed an extraordinary curiosity for understanding the mysteries of science. In 1905 he obtained his doctor's degree. In 1909 he became Professor Extraordinary at Zurich, in 1911 Professor of Theoretical Physics at Prague, returning to Zurich in the following year to fill a similar post. In 1914 he was appointed Director of the Kaiser Wilhelm Physical Institute and Professor in the University of Berlin. He became a German citizen in 1914 and remained in Berlin until 1933 when he renounced his citizenship for political reasons and immigrated to America to take the position of Professor of Theoretical Physics at Princeton.

RESEARCH

Daily, Seasonal and Monthly Variation of Middle-low latitudes Magnetic Field during Low Solar Activity

Binod Adhikari, Rupak Adhikari, Narayan P Chapagain, Nirakar Sapkota, Subodh Dahal, Drabindra Pandit

The variation of horizontal component of the geomagnetic field (Sq-H) is taken in the year 2003 to study the diurnal, monthly as well as seasonal variation of Sq-H using 4 geomagnetic stations across various latitudes and longitudes. We have carried out this work on “Variation of Horizontal Component of Magnetic Field in Low Solar Activity” to understand the variation of solar quite (Sq) current and its effect on the Earth’s surface.

ANALYSIS

Genetic analysis on tail feathers in Indian fantail pigeon

Ashraful Kabir M

Out of 50 squabs with 20 parents of White Indian Fantail fancy pigeons the tail feathers were counted the lowest 23 and highest 34 and this phenomenon is controlled by multiple allele. Within 50 squabs 10 individuals carried 32 tail feathers (20%) and the lowest 23, 24, 27, 33 and 35 (2%).
