They're made by resin infusion molding two halves, then putting a spar web in the middle and gluing it all together. The spar web glue is a thick paste that accounts for minor alignment / shape mismatch issues.
Quite ingenious in my opinion. It's definitely hard to hand-build a good product with large hours of specialist labor from expensive materials. And even more impressive to create a mass scaled process that produces still good enough products at reasonable cost.

After the introductory history, the rest of the article is a relatively straightforward overview/introduction to the engineering involved in making airplanes strong enough to fly.
