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 used in nanotechnology , 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 collaborated in the development of new inventions in combustion engineering , and is co-author of a patent for an internal combustion engine with increased thermal efficiency.
9/11 conspiracy theories
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 also cited by author David Ray Griffin.
