"It is clear that the chief
end of mathematical study must be to make the students
think."—John Wesley

HELLO, students and parents!
This is the 22^{nd} week of
school and the 6^{th} week of the 3^{rd}
9weeks grading period.
A reminder that if any student is absent,
they are expected to watch the video of that day’s
lecture, found either on the YouTube link on their math
page or in the
shared google folder,
so that they are up to speed when they return. Also, I
am in my classroom each morning at 8:00 AM for tutorials
(Wednesday duty, though, at 8:20 AM.)

MATH BIO:
George
Atwood
(1745 – 1807) was an English mathematician who invented
a machine for illustrating the effects of Newton's first
law of motion. He was also a renowned chess player whose
skill for recording many games of his own and of other
players, including FrançoisAndré Danican Philidor, the
leading master of his time, left a valuable historical
record for future generations.
Atwood was
born in Westminster, where he attended Westminster
School and in 1765 was admitted to Trinity College,
Cambridge.^{ } He graduated in 1769 with the
rank of third wrangler and was awarded the inaugural
first Smith's Prize. Subsequently he became a fellow and
a tutor of the college and in 1776 was elected a fellow
of the Royal Society of London.
In 1784 he
left Cambridge and soon afterwards received from William
Pitt the Younger the office of patent searcher of the
customs, which required but little attendance, enabling
him to devote a considerable portion of his time to
mathematics and physics.
George Atwood
died unmarried in Westminster at the age of 61, and was
buried there at St. Margaret's Church.
Over a century
later, a lunar crater was renamed Atwood in his honor.
MATH FACT:
The Atwood machine (or Atwood's machine) was invented in 1784 by
George Atwood as a laboratory experiment to verify the
mechanical laws of uniformly accelerated motion.
Atwood's machine is a common classroom demonstration
used to illustrate principles of physics, specifically
mechanics.
The ideal Atwood Machine consists of two objects of mass m_{1}
and m_{2}, connected by an inelastic
massless string over an ideal massless
pulley.
When m_{1} = m_{2}, the machine is in
neutral equilibrium regardless of the position of the
weights. When m_{1} ≠ m_{2}
both masses experience uniform acceleration.
Atwood's
machines can be pretty hairy. But no matter how
complicated they get, there are only two things you need
to do to solve them: (1) Write down the F=ma
equations for all the masses (which may involve relating
the tensions in various strings), and (2) relate the
accelerations of the masses, using the fact that the
lengths of the various strings don't change (also known
as "conservation of string").
F_{net} = F  f = (m_{2}  m_{1})g
 f = ma = (m_{1} + m_{2}
+ m_{eq})a
MATH QUOTE:
“What kind of
scale compares the weight of two beauties, the gravity
of duties, or the ground speed of joy? Tell me, what
kind of gage can quantify elation? What kind of equation
could I possibly employ?”—Ani
DiFranco
“Someone told
me that each equation I included in the book would halve
the sales.”—Stephen
Hawking
LIMERICK:
It may seem, with the angst it can bring,
That an Atwood's machine's a
harsh thing.
But you just need to say
That F
is ma,
And use conservation of string!
Have a great
week,
