<> Tautochrone in
MATHEMATICA and its Wonderful Connection to American Literature.
Huygens, Newton, Jean Bernoulli,
Euler, Lagrange and Herman Melville,
among others, have all been captivated by the special properties of the
tautochrone.
"It was in the left hand trypot of
the Pequod, with the soapstone diligently circling round me, that I was
first indirectly struck by the remarkable fact that in geometry all
bodies gliding along the cycloid, my soapstone for example, will
descend
from any point in precisely the same time."
from Moby Dick, 1851

<> Spirals in
Matlab: The Golden Ratio with Mondrian Shading.
Waldman finds calculations with spirals to be amusing "because an
approximation should be easier than that which is being approximated."

Wooden
Models of the Conic Sections
The National Curve
Bank honors
Francisco Treceño of Valladolid, Spain.
Treceño is a master wood lathe
craftsman.
Following a National Curve Bank tradition of supporting craftsmen
producing models of mathematically related forms, we are honoring
Treceño for his video demonstrating the union of wooden conic
sections.

The
Cannonball Curves of Thomas Harriot
The National Curve
Bank honors
Dr. Janet Beery, University of Redlands
and
Dr. Louis Talman of
Metropolitan State College, Denver.
Harriot investigated projectile
motion in the 1600s.
Among the new notation introduced in Harriot's algebra book Artis Analyticae Praxis published
by his friends in 1631, ten years after his death, were the symbols for
less than and greater than, < and >, that we use today.

The
Catenary or "Chain" Curve
The National Curve
Bank honors the catenary
created by Dr.
Gary Brookfield of
California State University, Los Angeles.
"All five of the finalists this year
deserve to be winners. The hinged dissections (#89)
and the circle (#85)
are nice; and the catenary is a classic curve if there ever were one."
A
member of the National Advisory Board of the NCB.
From Schooten's Latin
edition of Descartes.
Be sure to note Descartes' axes were not always perpendicular.

Visualize a Contour Map
The National Curve
Bank honors the contour maps
created by Dr.
Louis Talman of
Metropolitan State College, Denver.
"I'm teaching Calc 3 this term. My students are struggling
(as they always do) with visualizing things like this. I'm
showing this in class today!"
A
member of the National Advisory Board of the NCB.
From one of Descartes'
hallmark problems
investigating roots and
signs of polynomials.
Be sure to note the equals sign used by the printer was that of the
horoscope's Gemini.
