On the very small scale, i.e. quantum mechanics, a system is not in a specific state but there are different probabilities for the different states. By observing (measure) a physical property the system is forced into one of the possible states.

The problem is that not all properties are mutually measurable, when one property is observed the other one is changed (because the first observation forces the system into one specific state).

How is knowledge of science incomplete without knowledge of mathematics?

Science is a process of observing, hypothesizing (guessing) about natural laws, predicting the outcome of an experiment, then proceeding with the experiment and comparing the results with the predictions. The "predicting the outcome" part depends heavily on mathematics, in most of the sciences. Without this step science cannot proceed.


How does the mere observation change the outcome?

I am a commerce student and not familiar with quantum physics but here is my theory.. This are the imaginary values of an experiment. (Conducted normally i.e You are not observing)- 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 = 8 This is the imaginary values of the same experiment except this time you are observing it. (Consider your observation as the second value i.e 0=Not observing/1=Observing) 1 + 1 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 = 9 So conclusion is that in the first case the outcome of the experiment is 8 where as in the second case its 9. i.e Proving the change in output of an experiment with mere observation.

Observing an experiment


What is an outcome in a probability experiment?

It is the result of the experiment. It is the value of the observation.


What is a prediction about the outcome of the experiment?

The prediction about the outcome of an experiment is a hypothesis. It is basically an educated guess, and you see if your guess comes true or not.


Explain probability distribution?

The probability distribution of an experiment is a function that maps the probability of each possible outcome of the experiment to that outcome.
