Specialising in Petroleum Engineering: I am fascinated by compositional oil analysis, underbalanced drilling, reservoir analysis, decision making trees, applied mathematics and operations research.

My background contains International Baccalaureate (Natural Sciences, Economics, Mathematics, 2005-2008), Computer Science (2008), Engineering Physics and Mathematics (2009-2014) and now Petroleum Engineering (2014-).

My goal now is to find a strong international employer to whom I could write M.Sc. thesis related to some of the topics above. Anyone able to help are very welcome to contact.

Motivational material!

3 Principles of Success (Harford)

  1. Seek out and try new things.

  2. When trying something new, do it on a scale where failure is survivable.

  3. Seek out feedback (to determine your level of success) and learn from your mistakes as you go along.

revised Monty Hall problem extended with expectations i.e. prior probabilities
The strategy apparently requires a subgame perfect equilibrium to be optimal

comment Monty Hall problem extended with expectations i.e. prior probabilities
@Eupraxis1981 Good question. I have developed following. Strategy A is: "Monty chooses the door with the smallest expected probability until the last two doors. When only two doors left, Monty chooses the door with the highest probability." Strategy B is: "Monty chooses any door but not door with the highest probability and not the door with the lowest probability. When two doors left, Monty chooses the door with the highest probability." I don't know the optimal strategy, this may have been researched in the context of subgame perfect equilibrium in game-theory. Inspiring.

comment What is the system equation $f$ in Hamilton equation in $H=g+p^Tf$?
Researching this: found some awesome Harvard university material here and some, deep stuff! Taking time read this and dig into!

comment What is the system equation $f$ in Hamilton equation in $H=g+p^Tf$?
+1! I love this writing style! What is $H$? What is Hamilton equation? I am puzzled by Hamilton equations because there looks to be many of them, want to learn this detail thoroughly...

comment Euler equation for $\int_0^{\infty}e^{-rt}(x^2+2x+\dot x^2) \ \mathrm dt$? Is $\infty$ in the boundary open or closed?
So is the boundary closed or open in $\mathbb R$? I think $t_f$ is closed because no neighborhood coming from $\infty$. And $t_i$ is open because of the neighbourhood coming from negative side. So the $[t_i,t_f[$ is clopen (Its complement $]-\infty,0_-[$ is open set). Hmmm...I need to understand it better what closed boundary and open boundary means?

What about the third necessary condition for Hamiltonan $\frac{\partial H}{\partial u}=0$, where does it come from? $\dot x=f(x,t,u)$ is the first condition and $\dot p=\frac{\partial H}{\partial x}$ is the second.

@AlexanderVigodner Smart! $\dot x=f(x,t,u)$ is easier to remember than $\frac{\partial H}{\partial p}=f(x,t,u)$ even though meaning the same thing! But what does this mean in practise? Where are you getting this $f(x,t,u)$? I get lost if $f$ is not specified explicitly.
