| 9/11 Debate: Loose Change vs. Popular Mechanics pt. 3 |
 |
September 11, 2001 - five years after the attacks
many people are asking questions about what
happened on that day in New York, Washington and
Pennsylvania. Websites, articles, books and
documentaries have put forward a variety of
alternate theories to the government's account of
what happened. The most popular of these is a
documentary called "Loose Change." Now, a book
dealing with many of these theories has just been
published by the magazine Popular Mechanics, it's
called "Debunking 9/11 Myths: Why Conspiracy
Theories Can't Stand Up to the Facts." In a
Democracy Now! national broadcast exclusive, we
host a debate between the filmmakers of Loose
Change and the editors of Popular Mechanics on
9/11.

| Lecture 1 | Modern Physics: Classical Mechanics (Stanford) |
 |
Lecture 1 of Leonard Susskind's Modern Physics
course concentrating on Classical Mechanics.
Recorded October 15, 2007 at Stanford University.
This Stanford Continuing Studies course is the
first of a six-quarter sequence of classes
exploring the essential theoretical foundations of
modern physics. The topics covered in this course
focus on classical mechanics. Leonard Susskind is
the Felix Bloch Professor of Physics at Stanford
University.

****OOOPS! (4/4/08) Commentors guffpot and
DavidSChandler caught a couple errors I made
during my RedBull-fueled exposition. guffpot
correctly pointed out that I compared 200 years
vs. 300 million years incorrectly. Those two
numbers are apples and oranges, because the carbon
we transfer from the ground to the air in 200
years was not stored over a period of 300 million
years--it was stored FOR 300 million years, and
but was actively sequestered over a time period
probably much shorter. Really, it would be more
proper to compare the 200 years it's taking us to
transfer from the ground to the air to the time
period it took to transfer it from the air to the
ground. If anyone can find a credible figure for
that, please message me directly, and I'll include
it here.
DavidSChandler caught that I was off by a factor
of 100 in my scale model comparison of 200 years
to 300 million years. If my line on the board is
200 years, then 300 million years ago would be
about 10 miles--not 1000 miles--to the left.
Turns out I forgot to convert from cm to m in my
quick calculation. My bad. It's especially
ironic because I'm constantly warning my students
against making that same exact mistake! Ha! The
joke's on me. I guess it just goes to show
you--you can always be wrong. . .******

It All Ends: Index" for a roadmap to guide you
