Statistics reveal that 4% to 5% of sudden deaths are caused by a ruptured AAA [ 5, 6 ]. WebbQuantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.
