What is heisenberg uncertainty principle?is it true that it can explain almost everything.?

Question

including why blood is red in colour?

Answer 1

omigod no!!!
hiesenbergs uncertainity principle stated in the most rudimentary manner is this
For exceeding small particles, its is not possible to accurately identify their mass and velocity at the same time.

It has ramifications in advanced physics like for wave-particle theories, and is an extremely interesting thing to ponder about, but IT CAN NOT EXPLAIN EVERYTHING, THE LEAST BEING WHY BLOOD IS RED IN COLOUR.

Incidentally , blood is red in colour due to haemoglobin.

Answer 2

It only applies to very small things. Consider: If you are looking at an electron, how do you see it? Let's say you bounce a light particle off the electron into your eye. You know where it was right then, but you don't know where it's going, because the electron is small enough that the act of "seeing" it alters its course, and there is no way of knowing which way it was "really" going if you hadn't looked at it. Simply, the principle states that you can know where a particle is or where it is going, but not both at the same time.

Answer 3

"The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa."
A fundamental consequence of the Heisenberg Uncertainty Principle is that no physical phenomena can be (to arbitrary accuracy) described as a "classic point particle" or as a wave but rather the microphysical situation is best described in terms of wave-particle duality. The uncertainty principle, as initially considered by Heisenberg, is concerned with cases in which neither the wave nor the point particle descriptions are fully and exclusively appropriate, such as a particle in a box with a particular energy value. Such systems are characterized neither by one unique "position" (one particular value of distance from a potential wall) nor by one unique value of momentum (including its direction). Any observation that determines either a position or a momentum of such a waveparticle to arbitrary accuracy - known as wavefunction collapse - is subject to the condition that the width of the wavefunction collapse in position, multiplied by the width of the wavefunction collapse in momentum, is constrained by the principle to be greater than or equal to Planck's constant divided by 4π.

Every measured particle in quantum mechanics exhibits wavelike behaviour so there is an exact, quantitative analogy between the Heisenberg uncertainty relations and properties of waves or signals. For example, in a time-varying signal such as a sound wave, it is meaningless to ask about the frequency spectrum at a single moment in time because the measure of frequency is the measure of a repetition recurring over a period of time. In order to determine the frequencies accurately, the signal needs to be sampled for a finite (non-zero) time. This necessarily implies that time precision is lost in favor of a more accurate measurement of the frequency spectrum of a signal. This is analogous to the relationship between momentum and position, and there is an equivalent formulation of the uncertainty principle which states that the uncertainty of energy of a wave (directly proportional to the frequency) is inversely proportional to the uncertainty in time with a constant of proportionality identical to that for position and momentum.

Answer 4

It is basically the idea that you cannot know all aspects of a particle (location, velocity, etc.) because observing one aspect of it will cause another to change. If you find out what it's velocity is, then that act of observation will change its location, and vice versa. I really don't see how that can explain why blood is red in color, though. Blood is red because there is a protein in it called hemoglobin, which carries oxygen throghout the body by bonding it with iron atoms attached to the hemoglobin. This forms iron oxide (aka rust), which is red in color.

Answer 5

No, and Heisenberg didn't feel this way either. Enjoy the following link for more info.

Blood is red due to the color of hemoglobin, a compound containing iron, which often reflects red in many compounds.

Answer 6

Heisenberg's principle says that you cannot determine the position and velocity of an object at the same time.

Answer 7

We don't have a theory on our hands that can explain everything. Quantum field theory, of which this principle is a vital component (the others explained it in sufficient detail, I think) has made great advances, but It is only a partial theory : it doesn't describe the force of gravity. In fact, taken to the logical conclusion the equations of the theory state that gravity is impossible, which is....problematic.

Answer 8

Besides momentum and position, there are other attributes of particles that are uncertain. (ex. spin) HUP just talks about related attributes, not spcifically momentum and position. It's just that those are the most common examples.

Answer 9

You can read all about it on Wikipedia, it looks far too confusing for me to understand on a monday morning!

Answer 10

Of course it would explain everything he doesn't know
