Conquering flight: Claudius (Part 9)

Santino G.

One problem has pervaded all of my previous RC planes: weight. While I have been trying to minimize this one parameter in every plane since Augustus, it was only after I flew my third RC plane, Caligula, that I understood a more aggressive approach was necessary. This blog describes the construction of my fourth 3-channel RC plane, Claudius. Beginning with the fuselage, I maintained the same design used on the previous two; that is, foam board cut and folded so as to feature a square cross-section. It was, however, slightly shorter than Caligula’s. (This wasn’t an intentional decision; I simply … Continue reading Conquering flight: Claudius (Part 9)

Some physics pertaining to model rocketry

Santino G.

Despite my earnest pursuit of the model rocketry hobby, my efforts have been continuously undermined by the lack of one seemingly trivial thing: a launch site. This blog will not be focusing on this regulatory struggle (though, that would make a good post). Instead, I will collate some of the interesting physics I have learned regarding model rockets. The reader may rest assured, however, that my posts about my RC plane hobby will continue shortly. (Claudius is the next plane in construction and should be lighter than Caligula, Tiberius, and Augustus.) Center of mass (CM), center of gravity (CG), and … Continue reading Some physics pertaining to model rocketry

Novel interpretation of the Delta-Epsilon Proof (maybe)

Santino G.

While writing my calculus blog, I found (perhaps even discovered) a new way of thinking about the – (delta-epsilon) proof. This interpretation won’t cause any kind of epistemic revolution in mathematics, but I believe it’s a helpful pedagogical tool worthy of its own blog post. In case you have forgotten, the limit definition states the following (where and are real numbers): To prove a limit statement, we have to show that the limit satisfies this definition. How do we do this? We assume exists and show that, no matter what the value of is, there exists a corresponding . The … Continue reading Novel interpretation of the Delta-Epsilon Proof (maybe)
