As a Data Scientist, You Should Know About a Clever Horse Called Hans

In 1904, math teacher Wilhelm von Osten presented his horse called Hans to the public in Berlin, Germany. Von Osten claimed that Hans was smart enough to answer complex questions. For example, Hans could read the time. He could also identify the composers of music and the painters of famous paintings. Additionally, Hans could solve math problems. As shown in Figure 1, Hans did this by tapping a certain amount of times with his front hoof on a footstep.
