The Particle Accelerator Experiment That Might Rewrite the Historical past of the Printing Press


I am slightly nervous. In my proper hand, I am holding a priceless piece of human historical past. And that is not hyperbole. It is a weathered black binder, emblazoned with gold textual content on the entrance. In Gothic-style textual content it reads “A Leaf of The Gutenberg Bible (1450 – 1455).”

Sure, that Gutenberg Bible. These unique pages, that date again to the Fifteenth century, have come to the SLAC Nationwide Accelerator Laboratory in Northern California to be blasted by a high-powered X-ray. Together with the Bible pages, a Fifteenth-century Korean Confucian textual content, a web page from the Canterbury Tales written within the 14th century and different western and jap paperwork are set to endure the barrage. Researchers are hoping that inside the pages of those priceless paperwork lie clues to the evolution of 1 humankind’s most essential innovations: the printing press.

“What we’re attempting to study is the basic composition of the inks, the papers, and maybe any residues of the typefaces which can be utilized in these Western and Japanese printings,” stated imaging marketing consultant Michael Toth.

For hundreds of years, it was generally believed Johannes Gutenberg invented the printing press round 1440 AD in Germany. He is thought to have printed 180 Bibles (fewer than 50 are recognized to exist right this moment). However extra just lately, historians have uncovered proof that Korean Buddhists started printing round 1250 AD.

“What just isn’t recognized is whether or not these two innovations had been utterly separate, or whether or not there was an data stream,” stated Uwe Bergmann, a professor of physics on the College of Wisconsin. “If there was an data stream, it will have been, after all, from Korea, to the west to Gutenberg.”

To place it extra plainly: Was Gutenberg’s invention primarily based, at the very least partly, on Japanese expertise? That is the place the Stanford Synchrotron Radiation Mild Supply is available in.

A synchrotron is a particle accelerator that fires electrons into an enormous ring formed tunnel so as to generate X-rays (versus SLAC’s extra well-known linear particle accelerator, the two-mile lengthy LCLS). These X-rays give scientists the power to check the structural and chemical properties of matter. To see precisely how they’re utilizing SSRL to check the priceless paperwork, watch the video above.

By firing the SSRL’s thinner-than-a-human-hair X-ray beam at a block of textual content on a doc, researchers can create two-dimensional chemical maps that element components current in every pixel. It is a approach known as X-ray fluorescence imaging, or XRF.

“The atoms in that pattern emit mild, and we will monitor which components that mild should have come from on the periodic desk,” stated Minhal Gardezi, a PhD scholar engaged on the venture. 

Although the SSRL’s X-rays are highly effective, they do not harm the paperwork, giving scientists a holistic view of the molecules that make up the traditional texts. Additionally they give them the power to search for hint metals that historians say shouldn’t be within the ink. That may point out they most likely got here from the printing press themselves. “That may imply we might study one thing in regards to the alloys which had been utilized in Korea and by Gutenberg after which possibly later by others,” Bergmann stated.

In the event that they discover similarities within the chemical compositions of the paperwork, that would contribute to ongoing analysis into the variations and similarities of the printing applied sciences, and whether or not there was an alternate of data from East Asian cultures to the West.

Nevertheless, each scientist I talked with on the venture made it clear that even when similarities between the 2 paperwork are discovered, it would not definitively show one expertise influenced the opposite.

The paperwork are on mortgage from personal collections, the Stanford Library and archives in Korea. The analysis at SLAC is an element of a bigger venture led by UNESCO known as From Jikji to Gutenberg. The findings will likely be introduced on the Library of Congress subsequent April.
