What is Heisenberg's uncertanity principle?

Answer 1

Heisenberg's uncertainty principle concerns electron momentum and position.

It states that for any moving particle, its position and its momentum cannot be determined at a same time.

Mathematically, the product (dx)(dp) is greater than or equal to h/4(pi)

dx = uncertainty in position

dp = uncertainty in momentum

h = Planck's constant (6.620 x 10-34 J.s)

Answer 3

Principle that states that the position and velocity of an object cannot both be measured exactly at the same time, and that the concepts of exact position and exact velocity together have no meaning in nature.

Articulated by Werner Heisenberg in 1927, it applies only at the small scales of atoms and subatomic particles and is not noticeable for macroscopic objects, such as moving vehicles. Any attempt to measure the velocity of a subatomic particle precisely will displace the particle in an unpredictable way, thus invalidating any simultaneous measurement of its position. This displacement is a result of the wave nature of particles . The principle also applies to other related pairs of variables, such as energy and time.

Answer 4

According to Heisenberg's Uncertainty Principle, there is no way of accurately pinpointing the exact position of a sub-atomic particle, and this particle's exact momentum. Theoretically, one must be quite uncertain about one to get exact values for the other, and vice versa. This means that measurung both accurately and simultaneously is impossible - physically and theoretically.

Answer 5

In one of its simplest forms, if you are trying to measure both the velocity and position of a particle you cannot get better accuracy for both than some minimal product. If you measure one very accurately you will not be able to measure the other except with poor accuracy and vice versa.

There are many such paired properties to which uncertainty applies.

Answer 6

Heisenberg's Uncertainty Principle states simply that the act of observing something changes it. However, it is most commonly applied to the electron, as it is impossible to know both the momentum and position of an electron simultaneously, as measuring one affects the other.

Answer 7

In its simplest terms that no measurement can be made arbitrarily precisely. This is because measurement on the quantum scale always requires disturbing the system being measured by using other particles as probes.

The precise mathematical definition is in terms of the standard deviation.

Answer 8

Heisenberg's uncertainty principal states that certain pairs of characteristics of a sub-atomic particle, such as location and momentum, cannot both be known accurately at the same time. In the example given, the more accurately the location of a particle is determined the less accurately the momentum can be known.

Answer 9

the confirmation of reality and time is not real till observed
