We invite you to watch and think about the role of prediction in science. While the media and funding bodies tend to prefer when the research projects have practical applications (which often require making some new predictions), this is not how the most well-known theories were formulated. Many of the famous theories in Physics (and other sciences) were iterations of the earlier "clunkier" theories. This is discussed in the following video by the Last Theory YouTube channel.
Note that this channel is linked to Stephen Wolfram, who by some is regarded as a highly controversial figure in science. Although, he is the mastermind behind the Mathematica computer algebra system, which we like a lot (at least to help me with analytical derivations).
