*Mitra (Proto-Indo-Iranian, nominative *Mitras) was an important Indo-Iranian divinity. Following the prehistoric cultural split of Indo-Aryan and Iranian cultures, names descended from *mitra were used for the following religious entities:

Both Vedic Mitra and Avestan Mithra derive from an Indo-Iranian common noun *mitra-, generally reconstructed to have meant "covenant, treaty, agreement, promise." This meaning is preserved in Avestan miθra "covenant." In Sanskrit and modern Indo-Aryan languages, mitra means "friend," one of the aspects of binding^{[disambiguation needed ]} and alliance

The Indo-Iranian reconstruction is attributed to Christian Bartholomae, and was subsequently refined by A. Meillet (1907), who suggested derivation from the Proto-Indo-European root *mei "to exchange."

A suggested alternative derivation was *meh "to measure" (Gray 1929). Pokorny (IEW 1959) refined Meillet's *mei as "to bind." Combining the root *mei with the "tool suffix" -tra- "that which [causes] ..." (also found in man-tra-, "that which causes to think"), then literally means "that which binds," and thus "covenant, treaty, agreement, promise, oath" etc. Pokorny's interpretation also supports "to fasten, strengthen", which may be found in Latin moenia "city wall, fortification", and in an antonymic form, Old English (ge)maere "border, boundary-post".

Prof. Sugata Mitra is Professor of Educational Technology at the School of Education, Communication and Language Sciences at Newcastle University, UK. He is best known for his "Hole in the Wall" experiment, and widely cited in works on literacy and education. He is also Chief Scientist, Emeritus, at NIIT.

Mitra has been described as a polymath by the University of London, as his 30 years of research spans a wide range of disciplines.

He was born in Calcutta, India on 12 February 1952.

Starting with molecular orbital computation in the 1970s, Mitra discovered that the structure of organic molecules determine their function more than the constituent atoms (Crystal structure sensitivity of the band structure of organic semiconductors. S.C. Mathur and S. Mitra, Journal of Phys.C Solid State, 12, (2) (1979) UK).

After earning a Ph.D. in Solid State Physics from the Indian Institutes of Technology (IIT), Delhi, he went on to research energy storage systems - first at the Centre for Energy Studies in the IIT, and later at the Technische Universität, Vienna. This resulted in a new design for zinc-chlorine batteries that is now in use by the military (A design for zinc-chlorine batteries. S. Mitra, Journal of Power Sources, 8, 359-367 (1982) USA).
