D.R. is a young, aspiring mathematician. He attended the University of Washington, Seattle, graduated in 2021, and is currently at UCLA. You will find all his work in the website in the website link, or here.

Also, a shoutout to the Crusade of Answers, the only beam of hope left for those poor, sad, unanswered and unvoted questions.

A list of my interesting questions/answers:

• Group actions, Sylow, orbit-stabilizer

• All basic analysis inequalities come from convexity (see linked answers too)

• Barber paradox and Halting, Curry paradox and Lob

• Fourier transform cursedness

• Why is "convexity" important in mathematics?

• Product of Sines and Sums of Squares of Tangents

• Demystifying the Determinant

• The significance and acceptance of Helfgott’s proof of the weak Goldbach Conjecture

• Could *I* have come up with the definition of Compactness (and Connectedness)?

• "Continuized" Taylor Series? $\sin(x)=\sum \frac{(-1)^nx^{2n+1}}{(2n+1)!}=\int_{-1}^\infty \frac{\cos(\pi n) x^{2n+1}}{G(2n+1)}dn$?

• Construction of the complex exponential, extending real identities to complex, and proving $e^{ix} = \cos x+i\sin x$ from those identities

• What do cones have to do with quadratics? Why is $2$ special?
