Weak Stability Boundary

Weak stability boundary (WSB), including Low-energy transfer, is a concept introduced by Edward Belbruno in 1987. The concept explained how a spacecraft could change orbits using very little fuel. (Wikipedia).

Properties of Compactness

Compact sets enjoy some mysterious properties, which I'll discuss in this video. More precisely, compact sets are always bounded and closed. The beauty of this result lies in the proof, which is an elegant application of this subtle concept. Enjoy! Compactness Definition: https://youtu.be

Weak Stability Boundary and Capture in the Three-Body Problem - Edward Belbruno

Edward Belbruno NASA/AISR & IOD, Inc. January 19, 2011 GEOMETRY/DYNAMICAL SYSTEMS The problem of capture in the planar restricted three-body problem is addressed. In particular, weak capture is described, which occurs at a complicated region called the weak stability boundary, where the m

Limit levels + self-similarity in successor-limit hierarchy | Data structures Math Foundations 184

The successor - limit hierarchy exhibits interesting kinds of self-similarity, along the lines of fractals. One manifestation of this appears when we look at the levels of the limits in the sequence. In this video we go further in the sequence to really dizzying heights, probably obtaini
