But what about four-dimensional objects? The best we can really do is to look at three dimensional \u0026quot;shadows\u0026quot;. Just as a shadow of a three-dimensional object squishes it into the two-dimensional plane, we can squish a four-dimensional shape into three-dimensional space, where we can then make a sculpture of it. If the four-dimensional object isn\u0026rsquo;t too complicated and we choose a good way to squish it, then we can get a very good sense of what it is like. We will explore the sphere in four-dimensional space, the four-dimensional polytopes (which are the four-dimensional versions of the three-dimensional polyhedra), and various 3D printed sculptures, puzzles, and virtual reality experiences that have come from thinking about these things.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Professor Henry Segerman presents the Frontiers in Science Public Lecture \u00223D Shadows: Casting Light on the Fourth Dimension\u0022, author of Visualizing Mathematics with 3D Printing"}],"uid":"34469","created_gmt":"2017-04-10 13:29:07","changed_gmt":"2017-04-13 21:12:03","author":"nmcleish3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-10-27T20:30:00-04:00","event_time_end":"2016-10-27T22:00:00-04:00","event_time_end_last":"2016-10-27T22:00:00-04:00","gmt_time_start":"2016-10-28 00:30:00","gmt_time_end":"2016-10-28 02:00:00","gmt_time_end_last":"2016-10-28 02:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"590081":{"id":"590081","type":"image","title":"Frontiers in Science Public Lecture \u00223D Shadows: Casting Light on the Fourth Dimension\u0022","body":null,"created":"1491830711","gmt_created":"2017-04-10 13:25:11","changed":"1491830711","gmt_changed":"2017-04-10 13:25:11","alt":"","file":{"fid":"224802","name":"FrontiersInScience2016Poster.jpg","image_path":"\/sites\/default\/files\/images\/FrontiersInScience2016Poster.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/FrontiersInScience2016Poster.jpg","mime":"image\/jpeg","size":413641,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/FrontiersInScience2016Poster.jpg?itok=2_8FLKwX"}}},"media_ids":["590081"],"groups":[{"id":"1279","name":"School of Mathematics"}],"categories":[],"keywords":[{"id":"173647","name":"_for_math_site_"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
