In the next section, we'll look at the basis for quantum suicide - the Many-Worlds interpretation of quantum mechanics. These thought experiments are meant to prove or disprove interpretations - explanations for the whole of quantum theory. This is why quantum physicists are forced to create thought experiments based on the observations from the real experiments conducted at the quantum level. Of course, physicists aren't exactly throwing medicine balls at quanta to measure them, but even the slightest interference can cause the incredibly small particles to behave differently. He observed that one could not then use any statements about such things as 'the position and period of revolution of the electron. Uncertainty about an object's position and velocity makes it difficult for a physicist to determine much about the object. Heisenberg determined to base his quantum mechanics 'exclusively upon relationships between quantities that in principle are observable.' 1 By so doing he constructed an entryway to matrix mechanics. The same goes for observing an object's position. To know the velocity of a quark we must measure it, and to measure it, we are forced to affect it. This is the problem revealed by Heisenberg's Uncertainty Principle. What's more, you could calculate the velocity of the stool after you hit it with the ball, but you have no idea what its velocity was before you hit it. You can say where the stool was, but not where it is now. The problem is that when you throw a ball - especially a heavy one like a medicine ball - at something like a stool, the ball will knock the stool across the room and may even have enough momentum to bounce back. This relation expresses Heisenberg’s uncertainty principle. The product of the uncertainty in position of a particle and the uncertainty in its momentum can never be less than one-half of the reduced Planck constant: (4.3.1) x p 2. If you throw the ball at something across the street from you, it'll take longer to return, and you'll know that the object is far away. According to Heisenberg, these uncertainties obey the following relation. If you throw your medicine ball at a nearby stool, the ball will return quickly, and you'll know that it's close. Imagine that you're blind and over time you've developed a technique for determining how far away an object is by throwing a medicine ball at it. But it's actually easy to comprehend, and once you do, you'll understand the fundamental principle of quantum mechanics. Heisenberg's Uncertainty Principle sounds difficult to understand - even the name is kind of intimidating. Neither uncertainty can become small without the other becoming large. It is impossible to measure position x x and momentum p p simultaneously with uncertainties x x and p p that multiply to be less than h/4 h / 4.

Werner Heisenberg, a German physicist, determined that our observations have an effect on the behavior of quanta. This is known as the Heisenberg uncertainty principle. This is called Heisenberg's Uncertainty Principle.
