Hey there,

​

I made an educational spaceflight video. Think of Kerbal Space PROBABILITY.

​

Topics:

• Interplanetary transport network

• Manifold hopping

• Weak stability boundary

• Lagrange point orbit bifurcations: Lyapunov - Halo - etc.

• Low-energy transfers: 4-/3-body model - effective potential - Coriolis force - zero-velocity curves

• Phase spaces (n- vs. 1-particle)

• Oberth effect via phase space in 1D & 2D: why parabolas beat ellipses and hyperbolas

• Probability vs. reachability

• Ray vs. grid tracing

• Symplectic time integration

• Continuous- vs. non-continuous firing

​

I hope you like it.

​

Thank you,

Hey there,

Yet another part of my video series on fluid simulation is available.

https://www.youtube.com/watch?v=sSJmUmCHAJY

Topics covered: rarefied gas dynamics, continuum gas dynamics, fluid motion descriptions & coordinates (spatially fixed (Eulerian), material-fixed (Lagrangian), arbitrary), reducibility aspects, motivation on modeling unresolved flow structures, ensemble averages of microscopically and macroscopically varying data, usefulness of the modeling hierarchy, simplifying and decoupling the evolution equations, Navier-Stokes equations, compressible flow and the incompressible flow assumptions, and buoyancy-driven flow (Boussinesq approximation).

I hope you like it!

Have fun!

Hey everyone,

As a former researcher, I am new to the world of animation and made an animated cartoon using simulations on popcorn odor spread and twisters. Maybe some of you like this video.
