Random Matrices · Lesson
Three Classes, Three Edges Add samples for all three symmetry classes and compare.
Aperiodic Tilings · Lesson
Both orientations coincide, since a half turn is already a symmetry of the square.
Galois Theory · Lesson
The visual symmetry between the two lattices, with their order reversed, is striking.
Beautiful Varieties · Lesson
… Real Those nine points are arranged with an almost unreasonable amount of symmetry.
Ramsey Theory · Lesson
Symmetry-breaking cut the search from 2^7825 down to something a cluster could finish in two days.
Sphere Packing · Lesson
… or greedy constructions reach essentially the same place with none of the symmetry.
Beautiful Varieties · Lesson
A theorem about how such a symmetry can act on a surface with g handles caps the number of fixed circles at g plus one.
Homotopy Type Theory · Lesson
Prove It on refl, Get It Everywhere Pick symmetry, transitivity, or transport.
Aperiodic Tilings · Lesson
… look the same either way round — an S does, by half-turn symmetry about the midpoint.
Random Matrices · Lesson
They repel with an exponent set by symmetry: measurable.
Particle Physics · Lesson
The weak force also violates parity (left-right symmetry) and CP symmetry, making it essential for understanding the matter-antimatter asymmetry of the universe.
Beautiful Varieties · Lesson
Almost every record holder is built from symmetry : Barth's sextic and decic and Sarti's dodecic are invariants of the icosahedral group, which is why they look like spiky twenty-sided dice.
Minimal Surfaces · Lesson
It has no straight lines, no mirror symmetry planes, and divides space into two congruent, intertwined labyrinths.
Random Matrices · Lesson
Chaotic shapes give random-matrix spacings in the class fixed by the symmetry; integrable ones give Poisson spacings, with gaps of zero the most likely of all.
Random Matrices · Lesson
Neither has a spectrum, an eigenvalue, or a symmetry class.
Simple Groups · Lesson
This group also appears as the rotation symmetry group of the regular icosahedron, linking simplicity to geometric beauty.
Aperiodic Tilings · Lesson
… rather than on a different one — which contradicts it being a symmetry of a decomposition into distinct supertiles.
Random Matrices · Lesson
… a different question: if I knew nothing about this matrix except its symmetry, what could I still predict?
