Vaiseshika by Kanada Because of its emphasizing of the atomic structure of the universe, it is likewise called the substantial or Atomistic School or sometimes the Discriminating school, because it divides matter into eternally distinct elements, atoms, or infinitesimal parts. ... This school is considered by many as a branch of the Nyaya, and was founded by the sage Kanada, who lived about the same time as Gautama or Gotama, the founder of the Nyaya school. http://www.experiencefestival.com/vaiseshika
