307 Gilman

“It’s a sort of will-o-the-wisp thing,” Glenn Seaborg once said of the discovery of plutonium. “We saw it and then it disappeared. Then we saw it again and then it disappeared and then finally we saw it and we could confirm it.” That confirmation happened in Room 307 Gilman Hall, on February 23, 1941. It was a stormy night, Seaborg recalled. The 5 microgram sample of “element 94” had been bombarded in Ernest O. Lawrence’s 60-inch cyclotron. On May 29, 1941, Seaborg and his team filed a report of their results to Washington; by spring the following year, he had left for the Manhattan Project, and it was not until after WWII that the discovery was announced publicly. The room has since been declared a National Historic Landmark, and in the naming ceremony Seaborg returned to comment it had changed little in the 25 years since he’d worked there. Now in the care of chemical engineering professor John Newman, the room, with its equipment too antiquated for modern experiments, lies little used. Seaborg bequeathed the original sample of plutonium, housed in the old cigar box where he’d kept it, to the Smithsonian Museum.

Insightful post, thank you.
All things starts small, even the nuclear science.
Great post for this topic, I like the decoration for this, maybe you can share with us, about the tricks.
Interesting. The science it goes away.
Short but sweet and to the point, as far as I know the room has since been declared a National Historic Landmark.
Interesting. Crossed Dr. Seaborg path once when I was on campus. Missed the opportunity to take a class from him though because I was a transfer student. I think he also pioneered by using the plutonium to tag the human genome. I heard that the Life Science Building is demolished. Gilman Hall is stand?
… housed in the old cigar box. Great Idea!!! Interesting Artikel.
