### Quantum mechanics what do they mean by observing? [duplicate]

In quantum mechanics, you usually hear the phrase "the act of observing the state modifies it", but they never really define what they mean by "observing". For example, suppose we ...

### Does the observation instrument need to be conscious in order to change the interference pattern in the “Double slit experiment”? [closed]

I am an absolute amateur in physics but some questions haunt us all, don't they? In some places I hear/read that the conscious observer changes the pattern (https://youtu.be/XDpurdHKpb8?t=1559). In ...

### Questions about Schrodinger's cat [duplicate]

While I was listening to my teacher present the basic idea's of Schrodinger's famous thought experiment, he said that because we can not SEE the cat, the cat exists in some sort of position in which ...

### Definition of an “Observer” in regards to quantum physics and consciousness involvement [duplicate]

Each time I look video in regards to quantum physics there is almost always one point where they claim small matter can be represented by a wave function (can be everywhere but the item in question ...

### In QM does the observer really perturb the system to make a measurement?

It is commonly taught in introductory QM courses that in order to get to know the position or momentum of a particle, be it by "sending a photon" or similar experiments, the measurement necessarily ...

### How do we observe an electron? [duplicate]

When an electron is observed it acts like a particle and its wave function collapse. This statement is very famous in quantum mechanics, but what is meant by observing an electron? Which devices are ...

### What is an “observer” in quantum mechanics? [duplicate]

i read about the electrons double slit experiment, when both slits are open, electrons will form an interference pattern, but when there is a detector put to "observe" this weird behaviour, the ...

### How to draw a line between observation and minds? [duplicate]

When talking about quantum mechanics, a lot of people make the (pseudo-scientific?) argument that minds are required to collapse the wave function (and therefore, minds are important, we are back on ...

### The observer effect, how is related to death of human brain or consciousness? [duplicate]

Are we just a measurement device that interacts with quantum wave function/photons or something more? if not then can we die/be destroyed as observer?

### Observation effect in double slit experiment [duplicate]

I have watched some of the lectures given by Brian Greene and Lawrence Krauss about the observation conundrum encountered during the double slit experiment. Can anybody answer me this question? Is ...

### What is an observer that is not a whole living human person? [duplicate]

In current quantum models, name one or more objects that collapse an entangled waveform into a single classical particle other than a complete living human person. The "duplicate" I just read has an ...

### The observer detail of double slit experiment

I have been searching internet for a while and I couldn't find any detailed information about the observer type in double slit experiment of electrons. For example is the observer a camera or ...

### Wave function collapse and Schrodinger's equation without measurement

Will wave function collapse without measurement? Since all matters are described by wave functions, then in principle, I should be able to describe wave function collapse by Schrodinger's equation. (...
