Re: The engineering behind the San Antonio River Walk

I have lived in San Antonio for the past 2 years as an international student studying at UTSA. Never in my life, I have heard of San Antonio, Alamo, or even riverwalk before I moved to San Antonio, later I heard lot of great things about the Riverwalk and caves of San Antonio when I was researching. Personally, I doubt it, I agree it looks great in pictures, but I don't even know why people like it, the water is supe…

Everyone who is a fan of Pee Wee Herman has heard of the Alamo.

Interesting and refreshing choice to stick to a pure textual description without the usual torrent of photos. Needs frequent looking up of terms though :-) As for the river walk itself, living in Amsterdam predisposes you to treat the bone-dry, car infested asphalt and concrete jungles we call cities as weird places where humanity aggregates for ritualistic suffering. Discovering that San Antonio is different was a g…

Grady has a popular YouTube channel by the same name (Practical Engineering) with great photos, videos, graphs, and homemade demos. I am not a real engineer, but his videos bridge the gap between complex mechanical ideas and the layperson with well-designed experiments.

I watched the video version of this article. I think this is only the 2nd or 3rd video in his "practical construction" series on the channel.

I assume there's many more currently in the works, based on how long this one was in production during the replacement of the flood gates. I'm glad that the city, engineers, and contractors let him document the construction process and make a video about it.

I also thought it was pretty cool in a strange sort of way to see each of their logos in the video's credits. Not something I'm used to seeing from independent (if you ignore nebula studios) youtubers.

Earlier quoted context omitted.

As someone who went to public school in Texas, the textbooks in Texas are vetted by revisionists who still claim the Civil War was about states rights and not slavery, my civic teacher argued this repeatedly in the 1980s. A lot of kids are indoctrinated with the BS that downplay the slavery aspect, it's like the Big Lie of the south.

It was both. The succession was only about slavery. The economic motivation was only about slavery. The political motivation, after slavery, really was about states rights and that directly influenced all other factors even contributing to a weaker, fragmented, and less well funded military. The name for post civil war revisionism is the Lost Cause Movement , by the way. I too attended Texas public schools during tha…

I agree with most of your comment, but a bit more nuance with the last statement.

The taxes were core to supporting freedom among the colonists. These were not ordinary taxes. The Boston Tea Party, where they tossed the tea into the ocean as a mostly non-violent act of protest, was directly related to the Tea Act which followed the Stamp Act and other Acts that not just directly levied taxes onto the colonists, but actually made other sources of tea that weren't purchased from the British East India Company illegal.

Even worse, the colonists had no representation at all in Parliament or in England at all (hence the cry, "no taxation without representation"). Those accused of even heinous crimes or abuse in the colonies would simply be sent back to England to stand trial rather than by 'a jury of their peers'.

https://en.wikipedia.org/wiki/Tea_Act

This was in 1773, more than three years before the Declaration of Independence, and it marked a crucial turning point in the colonists' reaction to the Crown's acts against them, which had been ongoing for more than a decade at that point.

This was followed by the 1775 Declaration of the Causes and Necessity for Taking Up Arms, which you should read in its entirety (it's only a few pages), because it again predated by a year the final straw -- the "Declaration of Independence" in 1776.

The Declaration of the Causes and Necessity for Taking Up Arms, written by Thomas Jefferson, is a crucial document that is often overlooked. In it, the colonists again gave the Crown multiple warnings that they were not going to be abused like this. https://en.wikipedia.org/wiki/Declaration_of_the_Causes_and_...

Why did the King ignore it? He led the most powerful empire in the world, and probably the most powerful war machine that had ever been seen in history until that point. He was, literally, almost invincible. What did colonists thousands of miles away really think they could do to him? Why would he pay any attention?

That document is quite explicit as to exactly what crimes the Crown supported or directly undertook against the colonists (a bit old English and hard to read, but worth the read). And, unlike many other British colonies and subjugates such as India itself, the colonists were armed and they could make their own guns, which they did, beginning in the Connecticut River valley, in which could properly be understood as the very beginning of the Industrial Revolution.

The founding fathers recognized that guns in the hands of ordinary citizens were a bulwark against tyranny, which directly led to the drafting of the Second Amendment less than 15 years later (easily ratified in 1791).

Not coincidentally, the banning and seizing of small arms during the American Revolution were also what helped foment the Texas War for Independence as well, many decades later, and which led to the "Come and Take It" from Gonzales in 1831 (https://en.wikipedia.org/wiki/Come_and_take_it) and finally led to the Alamo and the Goliad Massacre in 1836 (https://en.wikipedia.org/wiki/Goliad_massacre), where the Mexican Army executed, en masse, the defeated Texian Army.

There is indeed a lot of revisionism going on, so the best way to resolve that is to actually read the contemporary documents from that time period and understand what people actually thought (or at least what they were brave enough to write down!)

Thanks for reading, even if you disagree.
