in today's lecture, we will discuss the untalked-of yet fascinating world of underwater shipwrecks, a topic that traditionally doesn't receive as much attention as it deserves. these remnants of maritime history serve as an instructional treasure trove, teaching us about the past in a way that textbooks cannot. we will repudiate common misconceptions, such as the belief that all shipwrecks have been discovered or that they hold no significant value. moreover, this exploration will act as a reset, challenging and expanding our predisjunctive notions of archaeology and history.
