PaschimBanga Vigyan Mancha was founded in 1986. Vigyan Mancha emerged as a common platform for expression of the intellectually advanced science concious people and the science clubs of West Bengal. Similarly at Kalna, Vigyan club became the Zonal committee of PaschimBanga Vigyan Mancha. In 1987 , some interested persons of Kalna organized a huge science fair at Kalna College. The committee, framed at that time for the exhibition, became known as Kalna Vigyan Club. The joint Secretaries of the club were Ashutosh Pal and Prof. Abhijit Sengupta. In 1988,  from Kalna Zonal Conference, Kalna Zonal Committee of PaschimBanga Vigyan Mancha started its journey.
The main objective of PaschimBanga Vigyan Mancha is to build a science concious society.  Through the history of two decades of various propagandas and projects, this organization for science popularization has become the largest organization of its kind. 
Kalna Zonal committee works in Block No. I & II of Kalna P.S. and Block No. I & II of Purbasthali P.S.  At present our member 1450 is              in this Zonal area. Every year new members are registered and renewal of existing members is also done. Kalna Zonal Committee works through 7 units within the 4 blocks.
