Description: Michio Kaku explains about the four fundamental forcers of nature supplimenting with some witty and great stories. Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that do not appear to be reducible to further basic interactions. There are four conventionally accepted fundamental interactions—gravitational, electromagnetic, strong nuclear, and weak nuclear. Each one is understood as the dynamics of a field. The gravitational force is modelled as a continuous classical field. The other three are each modelled as discrete quantum fields, and exhibit a measurable unit or elementary particle. en.wikipedia.org/wiki/Fundamental_interaction Some other resources - khanacademy.org/science/cosmology-and-astronomy/universe-scale-topic/light-fundamental-forces/v/four-fundamental-forces hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html youtube.com/watch?v=a-6skWBuHaE scienceworld.wolfram.com/physics/FundamentalForces.html physics.about.com/od/physics101thebasics/f/fund_forces.htm esa.int/Our_Activities/Space_Science/The_fundamental_forces_of_nature
