So I watched two youtube videos recently. "How a WWI Biplane works": https://youtube.com/watch?v=hgG4kGW_G9Y&t=2s and "How a P-51 Mustang Works": https://youtube.com/watch?v=hjsrqMe0B3s

I ended up surprised on multiple points. First, the WWI plane is simultaneously more complex and more well-thought-out than I assumed, but at the same time much flimsier than they might appear, and one gets a clear feeling for how young a field aviation was at the time. And then the WWII plane, designed maybe 25 years later. By comparison, the WWI plane is a folding chair strapped to a lawn mower tied to a kite, with some guns thrown in, whereas the WWII plane is just about one calculator and a booster rocket short of being the space shuttle. I honestly expected the difference to be less extreme.

Or maybe that's just German VS American engineering.

I went to the Udvar Haazy(sp?) air and space museum in the DC area recently. It was very fascinating to look at the relative sizes and complexity of different generations of fighter jets. The main thing that really struck me about the WWI and WWII planes is just how freaking small they were. The WWI planes definitely seemed like a lawn chair with an engine and some paper wings held together by string. The WWII planes were interesting as a comparison point for the modern fighter jets. They seemed obviously way more sturdy, but also so tiny.

I went and looked this up, but it fit my eyeballing estimates:

The b-17 had a max takeoff weight of about 32 tons. The F-15 had a max takeoff weight of 33.5 tons. An empty b-17 is heavier, and so its the average b-17. Compared to the Grumman F8F Bearcat (WWII fighter plane) with a max takeoff weight of 6.5 tons.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
