The Monte Carlo Method
## Problematic sentences
1. In Monte Carlo Integration:
and consider how to evluate this integral numerically.
2. In Monte Carlo Integration:
We can compute the expectation value of a function f(x) of this random variable as... (here starts an equation that is not recognised)
3. In The importance of sampling:
(After the graph) drops like $`1/\sqrt{N}`$ int the limit of $N→\infty$ - but we will never practically reach it.
4. In The importance of sampling:
From Eq. (2) we see that we so not need to sample uniformly.
5. In Why approximate importance sampling eventually fails:
This is related to the the very conter-intuitive fact thatin high-dimensional space "all the volume is near the surface".
6. In Metropolis Monte Carlo
Metropolis \emph{et al.} solved this as:
## Correct version
1. and consider how to evaluate this integral numerically.
2. Don't know what went wrong
3. drops like $`1/\sqrt{N}`$ in the limit of $`N\rightarrow\infty`$ - but we will never practically reach it.
4. You reference equation (2), but there is no eq (2) in the whole page
5. This is related to the the very conter-intuitive fact that in high-dimensional space "all the volume is near the surface".

## Problematic sentence
Instead of using an actual molecular dynamics data, here I use random correlated data that I generated using a [mathematical prescription] (https://www.cmu.edu/biolphys/deserno/pdf/corr_gaussian_random.pdf) that allows me to specify the correlation.

Because you're talking about the unit vector in the direction of the difference vector
Maybe it's meant well but I found it confusing since you also use r as the distance between 2 particleshttps://gitlab.kwant-project.org/computational_physics/lectures/-/issues/10Add explanation how to compute errors for polymer project.2020-05-27T08:12:22ZMichael WimmerAdd explanation how to compute errors for polymer project.https://gitlab.kwant-project.org/computational_physics/lectures/-/issues/9Add set of errata for Jos' book2021-02-07T22:33:24ZMichael WimmerAdd set of errata for Jos' bookErrors:
