In conjunction with the recent large donation of images by the physics department at the University of Illinois at Urbana-Champaign, AIP's Emilio Segrè Visual Archives (ESVA) received a donation of photos taken by Carl Pittman, a laborer on the betatron project in the late 1940s. Pittman took a series of photos, one of... which was published in the March 20, 1950, edition of Life magazine (which had a three-page story on the invention and operation of the 300-MeV betatron—a turning point in accelerator technology). As the images were taken in his capacity as a UIUC employee (he had to turn over his check from Life for the published image), there are no copyright issues involved in making them available. These unpublished images nicely complement photos of the betatron already held by ESVA.

Galileo: Getting past the icons
When we think about the heritage of physics, we naturally turn to its
icons: Albert Einstein, Isaac Newton, Galileo. Icons serve as
images—ideals which are often uncritically admired. The iconic Galileo
has no faults and no peers. If we adhere only to this part of the
heritage, we impoverish ...the history we tell and we limit our
understanding of what physics is.
Galileo illustrates how much lies beyond the icon. All physicists know
that Galileo discovered the law of falling bodies: the distance a body
falls is proportional to the square of the time of fall. Physicists may
not know just how difficult that discovery was for him. Because this
law is taught in the first semester of intro physics, teachers may
treat it as simple and obvious. Students often don't find it to be
either. Students may be comforted to realize that Galileo struggled too
in his investigations of falling bodies.
Galileo faced several
serious challenges in this project before he could even consider a law
or its proof. The only mathematics he or anyone else trusted in 1600
was the mathematics of ratios of like to like. This, compounded with
the surprising (to us) fact that neither Galileo nor any of his
contemporaries shared our concept of velocity, led to Galileo's first
developments. He defined velocity and he developed the math that
allowed him to investigate balls rolling down an inclined plane. By
1604 he had achieved these preliminary results that we take as
axiomatic. As Stillman Drake, the Galileo scholar, wrote in Scientific American
in 1973, "There is no logic to [Galileo's] foregoing procedure except
for the logic of discovery." Physics at the cutting edge is never
obvious.
As for his peers, Galileo proudly associated with mathematicians and
workmen in dockyards. His work on defining velocity involved both
physical principles and observing pile drivers at work. In 1597,
Galileo and hired artisans started to build a mechanical calculating
device, which he sold to architects and surveyors. Ten years later he
heard of Hans Lipperhey's telescope and set about improving it. He
needed something spectacular to attract patronage. But he also observed
the Moon and more, although so did Thomas Harriot (first), Christoph
Scheiner, and many others. The non-iconic Galileo did indeed face
challenges in his work. And he did not work alone.
Readers may learn more by visiting an exhibit at Philadelphia's Franklin Institute: Galileo, the Medici and the Age of Astronomy. The show runs through September 7. The American Astronomical Society has been working with IYA2009 organizers on the Galileoscope project. You can replicate Galileo's observations by using this high-quality, low-cost tool.

I hope you had an enjoyable Fourth of July weekend. In honor of the International Year of Astronomy 2009 (IYA2009), I've asked Greg Good, director of the Center for History of Physics, to offer some insights on physicist-astronomer-philosopher Galileo Galilei. —Fred

Dear Friends,
The Nobel Prize in Physics will be announced on October 6, 2009 and the Emilio Segrè Visual Archives wants to remind you of our large collection of Nobel Laureate portraits.
In 1958, William F. Meggers gave the American Institute of Physics
(AIP) his collection of photographs of 33 Nobel Laureates in
spectro...scopy and related fields, many of them signed. The Institute
subsequently undertook the task of augmenting the collection to include
photographs of all winners of the Nobel Prize in Physics, as well as
physicists who had received a Nobel Prize in other areas (for example,
Chemistry or Peace). The Gallery, dedicated to the memory of William F.
Meggers, is now displayed on the hallways outside the Niels Bohr
Library and here on our site.
The low res images, including our October Photos of the Month,
may be used at no cost in educational projects on students’ and
professors’ educational, non-commercial Web sites, while high quality
print and digital reproductions are available to authors and publishers
for purchase at low cost.
Can’t find what you’re looking for? Contact us as we are continually digitizing our holdings and acquiring new images.

Scott Prouty

Samuel Goudsmit Papers go online
The Niels Bohr Library and Archives recently received funding from the National Historical Publications and Records Commission for an exciting new project to scan and make available online the complete contents of the Samuel A. Goudsmit Papers. Goudsmit (1902–1978) was a Dutch-educated p...hysicist who spent his career in the US and was involved at the cutting edge of physics for over 50 years. He was an important player in the development of quantum mechanics in the 1920s and 1930s; he then served as scientific head of the Alsos Mission during World War II, which assessed the progress of the German atomic bomb project. Goudsmit became a senior scientist at Brookhaven National Laboratory and editor-in-chief of the American Physical Society. The papers consist of an estimated 66,000 documents, which include correspondence, research notebooks, lectures, reports, and captured German war documents; the collection is the most used in the library.
This is the first manuscript collection that we will digitize, and it will become one of the few complete history-of-physics collections online. We plan to make the collection freely available online by summer 2010.Read More

Why should physicists mark the 200th anniversary of Charles Darwin's birth and the 150th of On the Origin of Species? Of course we recognize the critical importance of Darwin's ideas for biology in the last century, but how is this relevant to physics? I submit that this is the wrong question. To my mind, we should ins...tead be asking: Why would one think Darwin is not important to all science? Click link to read more.Read More
