- How Star Wars Reinvented Cinema (YouTube)
In 1977 one of the most important films ever made was released, Star Wars. Following this, the film industry underwent a dramatic reinvention, becoming more commercially orientated. Many new blockbuster franchises were made in the wake of Star Wars - Indiana Jones, Back to the Future and Ghostbusters to name a few. This video explores the impact Star Wars had on the film industry, and how its legacy is still felt today.
- Mass (Wikipedia)
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body’s inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object’s mass also determines the strength of its gravitational attraction to other bodies.
