Jim Hoffman is a software engineer and a 9/11 researcher. Since early 2003, Hoffman has been actively researching the collapse of the World Trade Center (WTC) and other aspects of the September 11, 2001 attacks. He is also the co-author, with Don Paul, of Waking up from our Nightmare: The 9/11 Crimes in New York City, ISBN 9430960512 and the video, 9/11 Guilt: The Proof is in Your Hands, released in Feb, 2006.

9/11 research

Since early 2003 Hoffman has been researching the collapse of the World Trade Center and other aspects of the September 11, 2001 attacks. He is co-author, with Don Paul, of Waking up from our Nightmare: The 9/11 Crimes in New York City, and the video, 9/11 Guilt: The Proof is in Your Hands, released in Feb, 2006.

Hoffman's work has been a source of inspiration for the analysis of physicist Dr. Steven E. Jones. Hoffman's book and websites are cited in Jones' essay "Why Indeed Did the WTC Buildings Collapse?". Hoffman has also been cited by author David Ray Griffin in The New Pearl Harbor.

In order to more easily research the many complex details of the September 11th attacks, Hoffman put together a collection of original hypertext pages of research information. By developing a software tool for creating hierarchies of web pages, with references linking to source documents, he was able to easily navigate to any of its many pages. Originally developed as a research tool, the system later evolved into the 911-Research website.

Mathematics

Jim Hoffman has worked in applying scientific visualization of mathematics, which was instrumental in the discovery of the first new examples of complete, embedded minimal surfaces in over one hundred years. As described by Stewart Dickson:

"By the 1890s the study of minimal surfaces was thought to be exhausted — no new surfaces could be described mathematically which were non-self-intersecting (embedded) in three-space and which had vanishing mean curvature. However, in 1983 a graduate student in Rio de Janeiro named Celsoe Costa wrote down an equation for what he thought might be a new minimal surface, but the equations were so complex that they obscured the underlying geometry. David Hoffman at the University of Massachusetts at Amherst enlisted James Hoffman to make computer-generated pictures of Costa's surface. The pictures they made suggested, first, that the surface was probably embedded— which gave them definite clues as to the approach they should take toward proving this assertion mathematically— and, second, that the surface contained straight lines, hence symmetry by reflection through the lines."

Hoffman's work has been featured in articles in Science News, Scientific American, and Nature, and co-authored papers in Science and Macromolecules. He is credited with the discovery of new, three-dimensional morphologies for modeling block co-polymers, such as the Split-P surface (a hybrid of the P and G triply periodic surfaces) , and derived the first level set formulation for the Lidinoid surface.

He also is co-author of a patent for an internal combustion engine with increased thermal efficiency.
