What would I have done had I known

Abstract

Richard Weiss, a distinguished Member of the Scientific Committee and one of the founding fathers of Substantia, suddenly passed away on December 28, 2023. He leaves a terrible empty space in our minds and hearts. Richard promoted our Journal in the scientific community with great fervor, we will always miss his advices and support. We will miss his friendly dedication and long-term outlook. We will do our best to make the most of his wisdom. Now we believe that the best way to commemorate Richard and his participation in cultural and societal activities is to publish the last contribution he sent us in June 2023, on the anniversary of "Juneteenth", the liberation of African American slaves in the US.
