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.
While it may sound like something is terribly wrong with the joint, in most cases joint noise is nothing to worry about. Crepitus is the medical term that refers to joint noises, such as popping and cracking and creaking, particularly in the knees. Such joint noise can be quite disturbing and cause concern, especially when it shows up suddenly. In most cases, these noises are not indicative of any underlying problem.
