The reference links for the strip are in the next blog entry.
Now! Let's have a heated debate!
2013 update. Since I wrote this blog entry, this cartoon strip as well as many others on such subjects as homeopathy, chiropratic, evolution, and the supposed NASA Moon hoax landings, have been published in a book: Science Tales in the UK (Myriad Edtions) and How To Fake A Moon Landing in the US and Canada (Abrams). Here's the link to my main blog.
I am Darryl Cunningham and this is my main blog.
2. The most prominent cathedral to collapse was Beauvais, in 1248. It had flying buttresses. They didn't always work, nor did the builders who use them necessarily realize their limitations.
3. The Twin Towers stayed up just fine until a bunch of terrorists flew fully loaded airliners into them. Not even vaguely relevant.
So what you're saying is that anyone who can't always build a building correctly is stupid? By your definition there are an awful lot of stupid people in the world.
There WERE scientific advancements in the middle ages. There were also things like the abolition of slavery and oh yeah, women had rights too. There were books, poetry, art. And again, even science. The concept of zero was introduced in the middle ages. I don't think an opinion based on ignorance and bias is very relevant either. Having religion =/= stupidity and barbarism no matter how much you want to believe it does.
P.S. If the Twin Towers had been built properly to code, they would have been more likely to stand long enough for the fire to be put out. So um, actually I think it's perfectly relevant. And if you still don't think so, Google the Tacoma Narrows Bridge (1940).
