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.
Finding the Cause. Location: Where on the knee the patient feels pain can offer some clues about what type of injury or condition is causing the pain. For instance, pain on the inside or medial side of the knee (the side closest to the other knee) can be caused by medial meniscus tears, MCL injuries, and arthritis.
