There continues to be a fascination with the German atomic
bomb effort from World War II as evidenced by the May, 2022, article
The
elusive truth of Farm Hall. Below I discuss the play "Copenhagen" which made quite a
stir several years ago. Now there is to be a
play
based on the so-called
Farm Hall
Transcripts
[PDF].
These are transcripts of secretly taped conversations of the German scientists (including
Heisenberg) who were interned at Farm Hall in England after the War. It seems to be an endless
game to try to interpret from these conversations what the Germans did and did not know during
WWII about making a bomb.
The play
Copenhagen by the renowned playwright and author Michael Frayn (he
wrote "Noises Off", for example) which explores the occasion in 1941 when
Heisenberg paid a visit to Bohr in Copenhagen. The intriguing question, of
|

course, is "what did they discuss?" Some speculate that Heisenberg was trying
to obliquely warn Bohr about the German atomic bomb project. There has been
some new (Feb. 2002) light shed on what transpired through the release of some
letters from Neils Bohr (see also
New letters
expose war-time secrets).
There is also a "Heisenberg letter" which can be found at the
Who Was Werner
Heisenberg? site maintained by the Heisenberg family. There one can find
a number of Heisenberg's letters and writings translated into english.
There is also a resources page. The
London version of the play saw very enthusiastic
reviews while the Broadway version won several Tony awards! The play opened
in Toronto in January, 2004. There were good articles on
the show and Frayn in the
Toronto Star
and Globe & Mail.
I saw the opening-night
show on January 7 (which was great) and there were reviews in the
Star
and Globe & Mail. A
panel discussion of the scientific and ethical
issues addressed by the play happened on February 8, 2004, and I was one of the
panelists.
There were a number of symposia, both in
Europe and
the U.S.,
discussing the issues surrounding the play. For example, there
was a day-long symposium on the play
"Creating Copenhagen"
at the City University of New York
which examined the scientific and historical issues brought up in the play
as well as artistic issues associated with the writing and staging of the play.
Several of the presentations at this symposium were reprinted in the
July 2000 issue of
Physics Today including:
A
Historical Perspective on Copenhagen,
The
German Uranium Project, and
Werner
Heisenberg and Albert Einstein. There is also a nice bit of detective
work by Jeremy Bernstein in
The Drawing or Why History Is Not Mathematics from the journal
Physics in Perspective.
I also recommend the book by
Jeremy Bernstein entitled Hitler's Uranium Club.
The play was the subject for the University of Pennsylvania's
1999
Reading Project. At this site you can find a number of fascinating essays
about the play written by both artists and scientists.
There are also articles in
May 1999
CERN Courier and
June 1998 PhysicsWeb
discussing the play.
(There is another article by Jeremy
Bernstein on
Heisenberg's trip to Poland in 1943.) Finally, there are a
recent (January 2010) set of remarks entitled
Quantum imaging:
Scattered observations on "Copenhagen" which offer yet another take on
the play.
Over a hundred years ago (November 25, 1915 to be precise)
Einstein submitted
his paper on the General Theory of Relativity. Here are a few articles that commemorated this
event:
Nature Special Issue - General Relativity at 100 - November, 2015

There has been an increasing
interest in science shown by artists and vice versa.
which has lead to some interesting artworks - like those shown in the exhibit
Signatures of
the Invisible. There is also an interest from the scientist's side to
see how artists perceive science. Towards this end, the British Institute
of Physics commissioned the Rambert Dance
Company to produce a new work to celebrate the achievements of
Albert Einstein -
Celebrating Einstein with Dance,
Constant Speed (brochure)
premiered in 2005. The originators of the project were
interviewed in New Scientist.
Time is a particularly sticky problem and has been an obsession
of philosophers and physicists since, well, since time immemorial.
A nice overview is given in Time examined and time experienced (2018).
The topic has generated lots of musings such as
The Period of the Universe's Clock (June, 2020)
[The PRL article is Physical Implications of a Fundamental Period of Time]
and The origins of space and time (August, 2013).
Einstein's Clocks
(October, 2015) is a layman's discussion of the conundrum of time by Fermilab's Don
Lincoln. Check out the
essay entries (December 2008) to
fq(x) - Foundational Questions in Physics and Cosmology on
The Nature of Time. There is also a book by
Dan Falk called
In Search of Time: Journeys along a Curious Dimension
about which the Ottawa Citizen said
"Falk's book is what Hawking's A Brief History of Time should have
been." Falk has also posted an
essay on time travel which you might find amusing. In 2013, Lee Smolin
also put out a book on time called
Time Reborn which you may want to peruse.
There has always been plenty of verbiage on that old chestnut,
"Did time begin with the Big Bang?" Have a look at another video from Don Lincoln on
The Big Bang Theory
(October, 2014).
There's also The
First Second After The Big Bang (September, 2014) from the Universe Channel.
An August, 2010 article
Death Of The Big Bang, Or The Problem Of Time's Beginning also discusses the issue.
Various physics heavyweights have
weighed in on the matter in the past little while including Stephen Hawking on
The
Beginning of Time. There are several sites on how one experimentally
examines such a question including
Observing the Beginning of Time and
Beyond Einstein. Finally, this is a question with a long history of
theological debate. If you are interested in this kind of thing, have a look
at "Genesis: Science and the Beginning of Time"
[PDF] or
God and the Beginning of Time for a religious perspective. (I won't bias you
with my opinion but would be happy to discuss it).
A number of years ago all of
Einstein's scientific writings were made available online at
Einstein Archives Online.
English translations of his five famous papers from
the "miracle year" 1905 are collected in the book
Einstein's
Miraculous Year: Five Papers That Changed the Face of Physics.
Now (December, 2014) the Collected Papers of Albert Einstein including love letters,
report cards, personal thoughts and experiences are available online
here
both in the original german and with english translations. There's a nice article about the
release of the papers
- Inside the mind of Einstein: 44 years of writings released online -
from the December 6, 2014 Globe & Mail.
This is actually old, not new, but back in 2002 the electron double slit experiment was voted as
Science's most beautiful experiment. There are some other great one's in the list as well as
described in
Here They Are, Science's 10 Most Beautiful Experiments.
There is a new American Institute of Physics site on my hero
Rutherford.
There is also the Rutherford site
maintained by his biographer John Campbell.
There is
a nice book by
David Bodanis called E=mc2 (naturally)
which dissects, in a very entertaining manner,
each of the terms in Einstein's most famous equation. See also
Fermilab Today from July 5, 2013 for another discussion of
the famous equation. There are further discussions in Fermilab Today about
"Proving special relativity" -
episode 1
- Friday, March 21, 2014 and
episode 2 - April 4, 2014.
There is a special issue of Nature
on The Quantum
Atom which explores "the origin and legacy of Niels Bohr's radical view of the
nuclear atom, published one hundred years ago." We can now
"see" the Bohr orbitals as discussed in
Direct view of atomic orbitals (June, 2013),
'Quantum microscope' peers into the hydrogen atom, and
A New Look at the Hydrogen
Wave Function (May, 2013)
or watch electrons in motion as summarized in
Electron spectroscopy: Not just snapshots, real movies (July, 2013).
There is also the theoretical
question about how big atoms can be which is covered in
Theoretical physics: Sizing up atoms.
The foundations of the quantum world
are still hotly debated. For discussions of this have a look at:
The Oxford Questions on the
foundations of quantum physics (July, 2013),
Science and Philosophy: A
Love-Hate Relationship (July, 2013), and
Einstein as armchair detective:
The case of stimulated radiation (July, 2013).
See also A Quantum of Solace - Timeless Questions About the Universe.
Entanglement and the Uncertainty Principle are always hot topics. See, for example,
Measurement Uncertainty:
Reply to Critics (February, 2014),
Proof mooted for quantum uncertainty (June, 2013),
Spooky action gets collective (June, 2013),
Quantum uncertainty not all in the measurement (September, 2012),
Experimental demonstration of a universally valid error-disturbance uncertainty relation in
spin measurements (January, 2012),
Quantum theorem shakes foundations (November, 2011), and
A quantum take on certainty (June, 2011).
Or how about the lowly photon. Read
here for
the unlikely origin of its name. It is still
being studied, as evidenced by the July, 2013 articles
How Stable is the Photon? and
Detection of single photons via quantum entanglement.
You can read a reconstruction of a
lecture Einstein gave on the equivalence of mass and energy in Pittsburgh in 1934. Included in
|
Einstein lecturing in Pittsburgh in 1934 |
the article this picture of Einstein lecturing that was in the newspaper.
See how Albert Einstein did on his
performance review
at the patent office in Bern for the year 1905.
Ride a relativistic rocket! Physicists at
the Australian National University have created a computer program called
Real Time Relativity
that "allows the user to fly through a virtual world governed by relativistic physics." You
can download the program from here.
I also highly recommend
the book Einstein's Dreams
by Alan
Lightman who is
John E. Burchard Professor of Science and Writing and senior lecturer in
physics
at the Massachusetts Institute of Technology. The book is a beautifully
lyrical, thoroughly entertaining, and wonderfully short, meditation on time
through the artifice of imagining the daydreams of Einstein in 1905.
The book has spawned a
theatrical
adaptation, performed by Raleigh, NC's
Burning Coal Theater
Productions,
which garnered very good
reviews.
There is has always been a lot
of contention about the central principle of the Special Theory
of Relativity - namely, that the speed of light in vacuum
is a constant independent of the source and receiver relative speed.
Further, maintaining causality in Special Relativity requires that
nothing can go faster than the speed of light
in a vacuum and many attempts have been made to circumvent this, thus
obtaining "superluminal" speeds. For example, see
the article
"
Cosmic Laws Like Speed of Light Might Be Changing",
where the possibility that the speed of light
has changed value over time is discussed. A few years ago a number of experiments
involving light propogation through dense media generated a lot of
controversy and juicy headlines like
"Light
Pulses Flout Sacrosanct Speed Limit" (2002 - note the website),
"Faster
than a Speeding Light Wave" (2000), and
"Laser Smashes Light-speed Record" (2000).
Controversy also surrounded a paper in Nature
bearing the innocent sounding title of
"Gain-assisted
superluminal light propagation."
The abstract contained the line,
"The observed superluminal light pulse propagation is not at odds with
causality ..." although you wouldn't know it based on some of the media
coverage about it. This is nothing more than the old
group versus phase
velocity confusion according to Bob Park in
What's New.
The fascination with superluminal speeds is that it is related
to the least understood subject in physics (and philosophy) - time.
The onset of the new millenium produced a renewed fascination with
time.
You can take
A
Walk Through Time, a site on the evolution of time measurement from
The National Institute of Standards and Technology
(NIST) in the U.S.
The article
Seeing Faster by James Gleick in the New York Times Magazine gives
a fascinating glimpse into how flash photography has changed our perception
of time. The site also includes plenty of interesting links.
There seems a particular fascination with time travel including
"Time Travel"
from NOVA as well as
a
site with
"explanations" of relatvity and time travel.
You no longer have to
take my word for it. You can read many of the original papers (in English
translation) which are discussed in this course.
Not only has there been
renewed interest in the speed of light but there has also been an explosion
of interest in the brain of the man who made c a
universal constant. You could see
Samples of Albert Einstein's brain on display at the Mutter Museum
in 2011. And Albert Einstein's brain continues to fascinate - in Hamilton (2015).
In 1999,
researchers at McMaster University concluded that
Einstein really was smarter than the rest of us. Specifically,
"the parietal region of his [Einstein's] brain,
the area thought to be related to
mathematical reasoning, was found to be
15 per cent wider than average."
For complete coverage of the rather interesting history of the travels
of Einstein's brain (after his death, of course), have a look at
What
Became of Albert Einstein's Brain? There are also a number of books on the travels
of his brain including
Driving Mr. Albert
which was the cover review for the
July 30, 2000, New York Times Review of Books (see also the
review in the Globe
& Mail) as well as
Possessing Genius: The True Account of the Bizarre Odyssey of Einstein's Brain.
The story is covered in Chapter 14 of
Postcards from the Brain Museum. There's even
a children's book called
Nibbling on Einstein's Brain.
Einstein's Brain is the source of much art including
a 1994 documentary
Relics:
Einstein's Brain which chronicles the quixotic search for the brain
by a Japanese professor, a folk
album, and an art-science collaboration called
the einstein's brain
project.
Who says that relativistic effects aren't relevant to our everyday world!
A while ago I put a link to
Santa at Nearly the Speed of Light, the article "explaining" how the
answer to that age old question, "Just how does Santa Claus get to
all of those homes in one night?", lies in the
Special Theory of Relativity. There was actually a challenge to the
physics of the article which is gently responded to in
Santa's
World Revisited, an article
in the May, 2000 issue of
FermiNews, the newsletter from
Fermilab, the high energy
particle accelerator near Chicago. In the article is a link to a
website
where there are animations of how, for example, the Eiffel Tower would look
if you passed by at 90% the speed of light. It's worth a look.
Check out the
letter to the editor by
Cyril E. Challice, Professor Emeritus, University of Calgary, that was in
the March 2000 issue of
Physics in Canada.
It gives an interesting Canadian twist to the story of the observation of
the wave nature of the electron by Davisson and Germer.
There are various
online history "exhibits"
from the American Institute of Physics
including:
Albert Einstein: Image
and Impact
Werner Heisenberg and the
Uncertainty Principle
The Discovery of the
Electron
A Century of
Physics
You can also check out Heisenberg's first paper or read about Niels Bohr's letters to his
family and his fiancee in the years 1910-1912 -
Love, Literature, and the Quantum Atom.
The Experimental Evidence link from
the Particle Adventure is a
very nice web-based description of the experimental origins of quantum
physics, and in particular of Rutherford's groundbreaking experiments on the
structure of matter. There is also
All
About Light from
Fermilab which, through a discussion of light, cover much of the course
material.
In honour of the centenary of
the American Physical Society, the journal
Reviews of Modern Physics devoted an
entire issue to reviews of physics of the twentieth century. The following
articles seemed particularly relevant for this course:
"A Century of Relativity" by Irwin I. Shapiro
[pdf]
"Historic Foundations: Quantum
Theory" by Hans Bethe
[pdf]
"Experiment and the
Quantum Effects in One-photon and Two-photon Interference" by L. Mandel
[pdf]
"Experiment and the
Foundations of Quantum Physics" by Anton Zeilinger
[pdf]
Also, there is a new journal concentrating
on the history of physics called Physics in Perspective. The inaugral issue had an interesting article
entitled
"Why was Relativity Accepted?" [PDF]
which gives some of the social and historical context of the times. There is
also an article entitled
"Dispersion
in the Ether: Light over the Water" which concerns a history of the
measurements of the speed of light. Finally, there is an interesting story
about the history of the quantum called
Planck, the Quantum, and the Historians.
There are a lot of good websites devoted to
Einstein. Besides the AIP History site given already, there is
Albert
Einstein Online. There is also
Einstein
Revealed from the science program
NOVA.

Topics pre-2003
Although the actual material covered in the
course ends in 1925 with the birth of quantum mechanics,
the various topics are still "living" issues in the sense that scientists
continue to ponder and probe the foundations
of relativity and quantum theory. The following is just a sampling
of "web-accessable" papers
from the arXiv
e-print archive.

conclusions reached here could be,
and probably are, utter nonsense.]
