    In this video:

    The ancient Romans were a people famed for their architectural prowess, something no better demonstrated than by their ability to build almost perfectly straight and incredibly durable roads spanning expansive distances. For example, in Britain alone, the Romans built well over 50,000 miles of roads with the longest ruler-straight stretch spanning over 50 miles. They did all of this in an era without modern surveying tools, construction equipment, or even very accurate maps of precisely where their destination was for many of the areas. So how did they do it?

      I can understand having an ad before the video so you can be monetized, but then you have to stick an ad in saying this video is sponsored. So, not only do you get monitized, but then get sponsered too forcing people to watch or have to fast forward. Think I will unsubscribe. So should everyone else, then you can depend on your sponsor.

            You see, if you have point -A- and a point -B- and you put a spike in the ground at both points then tie a string to each spike it makes a straight line. Believe it or not we do the same today just with a laser.

                    (8:48) It's too bad the Romans didn't do like the Greeks did on their herma road markers. That is, put a penis on it. You know, for luck! ;) :P

                      4:17 to 5:04 is how they measured the direction of the road.
                      A schematic overview of the measurement tool would've been helpful.

                            I could care less if the Romans can build perfect straight roads so did the Inca empire..

                            I would be more interested in how people don't know about Operation Paperclip (which is where the US brought over Nazi scientists to continue expierments on Canadian and American citizens(mainly their minorities mental ill and homeless populations) these scientists expiermented on Jews in the Halocaust where most of your modern medicine and vaccines come from. Also 8 major big pharma companies broke off a Nazi company and those businesses still have Nazi mentality. Merck is one Bayer another.. NASA is founded by former Nazi scientists.. People rather be spoonfed information instead of doing actual research. But that's why people can go to your website (though I'm not sure how much research you do as well) .....

                                              5:49 "concrete" What would that have been made of, and how?

                                                I think they mention in the video they used plumb lines, sticks in the ground, and raw determination to draw straight lines from place to place.

                                                        It's kind of funny that he used the word "decimate" incorrectly considering this is a video about Romans. Decimate means to destroy or lose 1/10th of a legion (extrapolated to other items, people, or things) so it would have been 1.4 districts of the city destroyed (not 4 untouched out of 14) if it had truly been decimated.

Seems we forget that there are always a few people who are simply good at doing certain things even without being taught how to do them. My father taught himself how to draw, paint, and play several different musical instruments. I'd imagine there are people who can figure out how to make roads, sewers, waterways, etc.
