Category theory | Simplicial sets
In mathematics, a Segal space is a simplicial space satisfying some pullback conditions, making it look like a homotopical version of a category. More precisely, a simplicial set, considered as a simplicial discrete space, satisfies the Segal conditions iff it is the nerve of a category. The condition for Segal spaces is a homotopical version of this. Complete Segal spaces were introduced by as models for (∞, 1)-categories. (Wikipedia).

Kerbal Space Program - Getting to space (What Da Math)
Hello and welcome to What Da Math. In this introductory video I will try to demonstrate why it's not that easy to get into space and why going directly up will not actually help you achieve the necessary orbit. Thank you and please subscribe!

Colin Guillarmou: Segal axioms and resolution of Liouville conformal field theory
HYBRID EVENT Liouville conformal field theory is a 2 dimensional field theory introduced in physics in the 80's. Here we give a probabilistic construction of the amplitudes of Riemann surfaces with boundary for this field theory, and we prove that they satisfy the so called Segal Axioms. T

Tashi Walde: 2-Segal spaces as invertible infinity-operads
The lecture was held within the framework of the Hausdorff Trimester Program: Symplectic Geometry and Representation Theory. Abstract: We sketch the theory of (infinity-)operads via Segal dendroidal objects (due to Cisinski, Moerdijk and Weiss). We explain its relationship with the theory

When catching prey underwater snakes use two main techniques: the frontal strike and the lateral strike. By studying real snakes in the lab at ESPCI/MNHN, Marion Segall was able to recreate the setup using a 3D-printed snake head and laser visualisation techniques, which allowed for the fo
