+// Content
+= N-body forces and analytical solutions
+
+== Objective
+Implement naive N-body force computation and get an intuition of the challenges:
+- accuracy
+- computation time
+- stability
+
+$=>$ still useful to compute basic quantities of the system, but too limited for large systems or the dynamical evolution of the system
+
+
+== Overview - the system
+Get a feel for the particles and their distribution. [Code at @task1:plot_particle_distribution[]]
+#image_cell(t1, "plot_particle_distribution")
+
+#code_cell(t1, "plotting")
+
+== Inspecting the data
+#code_cell(t2, "plotting")
+
+#image_cell(t2, "plotting")
+
+
+== Density
+Some images about the density
+
+== N Body and variations
+sdsd
+
+== Relaxation

+= Default Styling in diatypst
+
+== Terms, Code, Lists
+
+_diatypst_ defines some default styling for elements, e.g Terms created with ```typc / Term: Definition``` will look like this
+
+/ *Term*: Definition
+
+A code block like this
+
+```python
+// Example Code
+print("Hello World!")
+```
+
+Lists have their marker respect the `title-color`
+
+#columns(2)[
+  - A
+    - AAA
+      - B
+  #colbreak()
+  1. AAA
+  2. BBB
+  3. CCC
+]
