The dispute of 1689 between Newton and Huygens was won by Newton (he was by far the more important person) but in reality, Newton was wrong (*). With all the information available at that time, the “guess” that light is made of corpuscular objects should not have been tenable at …
We currently make some more experiments for the density of wave fronts project. We conjecture there for example that for any polygon wave fronts become dense. In cases like eqilateral triangles or right angle triangles this can be proven because doubling produces a parallelogram that tessellates the plane. This is …
Here is again some Mathematica code. What is new here, that we do not bother to solve the Lax differential equations but directly compute the deformation using QR which is exact. We build a small 3 sphere as a simplicial complex G, then build the Dirac matrix B=D (we chose …
This is a bit a blast from the past. While thinking about waves, I thought of this little C program, I wrote in April 2000 (we moved in June 2000 to Boston which was quite an adventure, our car broke down, and I drove from Austin to Arlington twice). As …
