It is home to the popular zoo, the art museum, the history museum, and the science museum, which also became an important part of our conference experience. The SC25 technical reception was held at the science museum \u2013 an evening of drinks, good food, and numerous opportunities to chat with other participants in a relaxed atmosphere. The combination of scientific flair and informal atmosphere made this evening a special highlight.<\/p>\n<div id=\"attachment_23461\" style=\"width: 235px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-23461\" class=\"size-medium wp-image-23461\" src=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-225x300.jpeg\" alt=\"Gateway Arch in St. Louis, USA\" width=\"225\" height=\"300\" srcset=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-225x300.jpeg 225w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-768x1024.jpeg 768w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-1152x1536.jpeg 1152w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-1536x2048.jpeg 1536w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_0055-1-scaled.jpeg 1920w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/><p id=\"caption-attachment-23461\" class=\"wp-caption-text\">Source: Own illustration<\/p><\/div>\n<div id=\"attachment_23462\" style=\"width: 310px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-23462\" class=\"size-medium wp-image-23462\" src=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-300x225.jpg\" alt=\"History Museum St. Louis, USA, exterior view\" width=\"300\" height=\"225\" srcset=\"https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-300x225.jpg 300w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-1024x768.jpg 1024w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-768x576.jpg 768w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-1536x1152.jpg 1536w, https:\/\/blog.rwth-aachen.de\/itc\/files\/2025\/12\/IMG_20251121_174941868-1-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-23462\" class=\"wp-caption-text\">Source: Own illustration<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #00549f;\">Conclusion and Outlook for SC26<\/span><\/h3>\n<p>SC25 in St. Louis was a success for us in every respect.
