If you want to understand the debates surrounding hydrostatic shock, you should watch this video. I don’t have a strong opinion about that subject (a rarity for me), but I think after watching this video you will understand why some people believe in it even though the topic is not mentioned.
If you have heard about Hannibal or the Battle of Cannae that almost brought Rome to its knees but you don’t really know more then that, then this video is for you. Best overview of the battle I have yet seen (and I have seen a few). Part of a much longer series that leads up to this but you can skip them if you lack the time (even though they are all good). I will probably make the entire series an “Educate Deb” thing at some point but we are ways off of that.
