What is Applied: Definition and 1000 Discussions

Applied science is the use of the scientific method and knowledge obtained via conclusions from the method to attain practical goals. It includes a broad range of disciplines such as engineering and medicine. Applied science is often contrasted with basic science, which is focused on advancing scientific theories and laws that explain and predict events in the natural world.
Applied science can also apply formal science, such as statistics and probability theory, as in epidemiology. Genetic epidemiology is an applied science applying both biological and statistical methods.

    Can Kepler's 2nd Law be applied to more than one planet?

    I saw an explanation for why Jupiter has a slower tangential velocity in its orbit compared to inner planets and it stated: "Remember that by Kepler’s second law, the planets each sweep-out the same area in the same amount of time. The outer planets’ elliptical orbits are considerably larger...

    Can Ampere's law be applied to 3D loop?

    Usually in textbooks Ampere's law is just illustrated using 2D loops which forms a plane. Can the law be applied to 3D loops which cannot form a plane surface within the loop? In a 3D loop which surface should we count when we count the current? In 2D case it is easy because there can only be a...

    Force Applied -- General doubt about pushing 2 blocks on a floor with friction

    Force" F"is applied on M1 .Although force applied is not directly on M2,but it will also experience this force" F" via M1,right? But I don't think it is correct.Because it implies that no matter how big the force on M1,the net force on M1 will always remain zero.And there will be unbalanced...

    Why do resistors always cause a voltage drop equal to the voltage applied?

    Consider a wire connected to a battery. Now,potential is analogous to the energy of the particles.And potential in a resistor drops because of the friction inside the resistor(considering there is no friction along the wire and outside the resistor).So the friction determines how much energy is...
