Pseudorandom sequences typically exhibit statistical randomness while being generated by an entirely deterministic causal process. Such a process is easier to produce than a genuinely random one, and has the benefit that it can be used again and again to produce exactly the same numbers - useful for testing and fixing software.
Another similar explanation suggests that when you âcrackâ your knuckles, or any other joint, it expands the space between your bones, creating negative pressure that draws synovial fluid into the new gap. This influx of synovial fluid is what causes the popping sound and feeling when you crack a knuckle.
Patients may experience a symptom of popping called a mechanical symptom.. This may feel as though something is caught within the knee and is popping as the knee bends back and forth. This type of popping symptom is often a sign of a meniscus tear or a loose piece of cartilage within the joint. The torn meniscus or loose cartilage may catch in the knee as it moves back and forth causing a popping sensation.
