However, in this role, collapse is merely a black box for thermodynamically irreversible interaction with a classical environment. Calculations of quantum decoherence predict apparent wave function collapse when a superposition forms between the quantum system's states and the environment's states. Significantly, the combined wave function of the system and environment continue to obey the SchrÃ¶dinger equation.
Exercise can exacerbate the burning sensation in knee. Rheumatoid arthritis is an autoimmune condition where the body attacks its own tissues and causes joint inflammation. Knee bursitis occurs when there is an inflammation in the fluid-filled sac in the knee joint.
Other conditions that cause knee pain include: 1  Bursitis. 2  A bursa is a sac of fluid that resides below the skin overlying your joints. 3  Overuse, a fall, or repeated bending and kneeling can irritate the bursa overlying the knee cap (patella), causing pain and swelling. The iliotibial band is a piece of tough tissue that runs from your hip down to the outer part of your knee. 2  If it's irritated by overuse or other problems, it can become inflamed and cause pain on the outer side of the knee.
