I'm afraid I have to disagree entirely. Nothing in the article was too far out of the bounds of what I would consider normal. Sure, some of the technical language (entropy, Gaussian) might not be encountered unless you're into nerdy stuff, but that's an easy dictionary search away. The rest can be inferred from context (I desperately hope you have been taught how to do this?).

Example: the relationship between Romanesque and Baroque art. Never heard of it before. I inferred it from a vague knowledge of history and the rest of the paragraph. It's not magic; anyone can do it, including you.

I'm practically begging you here: if the above article was difficult for you, reread it as many times as you need in order to understand it. Then go seek out more works that are difficult to understand and conquer those too. If we lose the ability to do this, we're in for a long slide into Hell.
