Triangles abound in our newly released learning module: Classifying Triangles by Systems of Line and/or Angle Properties.
On April 8, 1982 while on sabbatical in Washington, Israeli scientist Dan Shechtman observed crystals with five-fold symmetry.
The problem? This was considered impossible.
He was mocked for his discovery and asked to leave his research group. But he stood by his findings despite criticisms, some from none other than Linus Pauling, one of the towering figures of science and the only person to twice receive the Nobel prize unshared; to the day he died, Pauling never accepted Shechtman’s findings.
“The main lesson that I have learned over the years is that a good scientist is a modest and attentive scientist,”
— Dan Shechtman
Both Shechtman and Pauling used Zometool for modeling quasicrystals, as it can be used to model all quasicrystalline shapes.
Paul Hildebrandt says “Marc Pelletier and I glued those balls and painted those struts by hand; quasicrystal researchers were among our very first customers”.
Below, a beautiful x-ray of quasicrystals and some related links:
