Is measurement the same as observation?
Observation requires a conscious observer, measurement doesn’t. so who tells a quantum system to collapse?
What type of observation is a measurement?
Quantitative observations
Quantitative observations involve measurements or estimates that yield meaningful, numerical results. Qualitative observations yield descriptive, nonnumerical results. Although all the observations we can make on a phenomenon are valuable, quantitative observations are often more helpful than qualitative ones.
What does it mean to observe a particle?
In experimental particle physics observation of a particle means detection of its interaction with the specially designed apparatus sensitive to the electromagnetic interaction (alias ionization) with the detector’s medium.
What are measurements from a sample called?
A descriptive measure computed from the data in a sample is called a statistic. A descriptive measure computed from the data in a population is called a parameter. In practice, the values of parameters are usually not known.
What are the 4 types of observation?
There are several different approaches to observational research including naturalistic observation, participant observation, structured observation, case studies, and archival research.
What type of observation are there?
In the scientific method, two types of observation exist: quantitative and qualitative.
- The Scientific Method Simplified.
- The Power of Inquiry.
- Quantitative Observations.
- Qualitative Observations.
Does the observer need to be conscious?
No. In QM, observation is just measurement, and does not require consciousness.
Can a particle be an observer?
When a quantum “observer” is watching Quantum mechanics states that particles can also behave as waves. Once an observer begins to watch the particles going through the openings, the picture changes dramatically: if a particle can be seen going through one opening, then it’s clear it didn’t go through another.
Does observation alter an event?
In physics, the observer effect is the disturbance of an observed system by the act of observation. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner. While the effects of observation are often negligible, the object still experiences a change.
How do electrons know they are being watched?
The electron doesn’t ‘know’ anything- it simply interacts with energy and matter in accordance with the laws of physics. What physicists do is to design their experiments to investigate the nature of those interactions.
