Light

(Note -- WEDNESDAY)

Mohammad Sayeh

Slow light  (photons calmed)


[recording]




Two papers (click): 

• Stopped light
• Slow light

And the book suggested by Mohammad:  "Fast Light, Slow Light and Left-Handed Light" by P W Milonni, 2005.  [Amazon,  PDF]

In comments use dollar signs and latex to get math formating.  For instance $\frac{7}{3}=\det\begin{bmatrix}a&b\\ c&d\end{bmatrix}$.

Origami

30 April 2020

William Holt

Origami, math between the sheets (of paper)

Recording (59 min).

William goes over a number of things, which include his method of folding paper into n equal sections for arbitrary n.  

Interlude

Two items:

The text Christian Rose mentioned (and currently reads) can be downloaded here.   (It contains a nice chapter on math of lattices.)    See also the lectures recorded at Oxford.  Thanks, Christian.

The lectures on Knot Theory started.  Here are recordings of the first four:

Lecture 1 (Roger Fenn)

Lecture 2 (Louis Kauffman)

Lecture 3  (Roger Fenn)
Lecture 4  (Louis Kauffman)
Lecture 5  (Roger Fenn, 1 May)

Yous probably remember Louis from his visits at Carbondale.
