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.

    Other BA in Astrophysics -> MS in Applied Physics -> PhD in Applied Physics

    Hello, I am about to attend the University of Hawaii at Hilo as an Astrophysics major. I intend to complete my education through getting my PhD in Applied Physics, but I wanted to know if it was necessary to get a Master's? I would think so because of getting a BA in Astrophysics instead of AP...

    Fluid that emits light when applied voltage, got tips?

    Hi, Does anyone know of any fluid that emits light when current is running through it? Why? To feed to a flower, apply low voltage and make it glow. Florescent light isn't enough and bioluminescence isn't my area of expertise so turning a flower into a LED is going to be my approach. All tips...

    I Virial theorem as applied to hydrogen atom

    In the virial theorem the numerical value of the average potential energy within a system is exactly twice that of the average kinetic energy. I know the theorem is proved mathematically but to me it seems a coincidence that one value is exactly twice the other value. I find that interesting. I...

    David Suzuki and Applied Physics vs. Theoretical Physics

    Another thread reminded me of this. Sometime, probably in the 70's Suzuki said something like this, for something to be "real" it has to have a least one piece of retrievable information. One example he gave that I remember was a point in space. I remember this example because of his...

    A Can the quantum Zeno effect be applied to the Higgs field

    This sounds weird and i suppose that i got some concepts wrong. For all i know, the higgs field may be metastable and the zeno effect states that the rate of decay for an unstable system can be changed by interaction. Can the zeno effect be applied to the higgs field if it is indeed metastable?
