it should be called as unpredictability rather than uncertainty principle because the event is certain but we cannot predict it.

this is related to the philosophy of quantum mechanics , because according to quantum theory if we can't predict the event exactly with the help of any theory or equation the event then will be uncertain.jayaramas said:it should be called as unpredictability rather than uncertainty principle because the event is certain but we cannot predict it.

This is not correct according to QM. You can only speak of things that you can measure. Since you cannot know what the event is until you measure it, and you cannot be certain of the outcome of the measurement until you perform it, there is no certain event.jayaramas said:it should be called as unpredictability rather than uncertainty principle because the event is certain but we cannot predict it.

Still, unpredictability is not a good word. We don't have the means to observe "expected" behaviors as they happen. We have the means to extrapolate from the behaviors of lots of particles (statistically), but that's pretty much the end of the classical regime, IMHO. Uncertainty is not a bad word to describe what happens to classical physics when we start looking at individual particles, or even lots of particles. Their collective behavior is predictable, but their individual behavior is not.jayaramas said:every one will give example of tossing a coin.but the coin shows head or tail according to physical law of force given for tossing. if you have a good machine, we can give desired force and get head or tail that is what ever we want. it is not uncertain event, if we measure exact force. similarly, sub atomic particles. so, i think we have to change the philosophy of physics.
In the Stern-Gerlach experiment, the silver atoms are all in the same superposition state. According to you, they should all deflect in the same direction, but they don't. Half of them deflect in one direction and half in the opposite direction.jayaramas said:every one will give example of tossing a coin.but the coin shows head or tail according to physical law of force given for tossing. if you have a good machine, we can give desired force and get head or tail that is what ever we want. it is not uncertain event, if we measure exact force. similarly, sub atomic particles. so, i think we have to change the philosophy of physics.

What exactly do you mean by inconsistent? If you mean it in the logic sense I don't really get your point.Runner 1 said:I like "inconsistency principle" better, because identically prepared systems don't give consistent measurements :)
Uncertainty refers to a lack of knowledge or information about a particular situation or outcome. It is a state of being unsure or having doubts. On the other hand, unpredictability refers to the inability to predict an outcome or event with certainty. It is a state of being unable to foresee or anticipate what will happen.
Uncertainty can have a significant impact on decision making as it can make it difficult to determine the best course of action. It can lead to hesitation, second-guessing, and even avoidance of making a decision altogether. In some cases, it may also result in making a decision based on incomplete or inaccurate information.
While uncertainty cannot be eliminated entirely, it can be managed or reduced through various strategies. These may include gathering more information, seeking expert opinions, conducting research and analysis, and using techniques such as risk assessment and scenario planning.
No, unpredictability can have both positive and negative consequences. While it can create challenges and obstacles, it can also lead to new opportunities and innovations. In some cases, unpredictability can also be exciting and provide a sense of adventure.
Uncertainty is a fundamental aspect of scientific research, as it is impossible to know all the variables and outcomes of a particular experiment or study. However, scientists use various methods, such as statistical analysis and peer review, to minimize uncertainty and increase the reliability and validity of their findings.
