A screen recording of my using the Memsora app to review a flashcard. The card is displaying an animation of a chess opening. You can see me typing in "Ruy Lopez: Exchange Variation", which is the correct answer for which opening it is.

A screenshot of some documentation I wrote for Resyntax. It reads: "4.5 Expansion Analyzers" "An expansion analyzer examines the fully expanded form of a program and reports facts about it as a syntax property bundle whose syntax paths refer to subforms of the expanded program. Resyntax translates those paths back to the corresponding subforms of the original unexpanded program and attaches the reported properties to them, making information that is only discoverable after macro expansion available to refactoring rules. Expansion analyzers are an as-yet undocumented work in progress; a future edition of this grimoire will describe them properly."

A photo of part of a textbook page that reads: "The search for recurring ideas exists at the proof-writing level and also on the larger expository level. I have tried to give the course a narrative tone by picking up on the unifying themes of approximation and the transition from the finite to the infinite. To paraphrase a passage from the end of the book, real numbers are approximated by rational ones; values of continuous functions are approximated by values nearby; curves are approximated by straight lines; areas are approximated by sums of rectangles; continuous functions are approximated by polynomials. In each case, the approximating objects are tangible and well-understood, and the issue is when and how well these qualities survive the limiting process. By focusing on this recurring pattern, each successive topic" (The text continues beyond the visible portion of the image.)

A great beautiful tree on a hillside, its branches crawling up and along the angled ground like a Lovecraftian horror searching for pieces of reality to anchor itself with
Another photo of part of a page of the textbook, beginning a new section: "4.2.2 More Bouncing Balls and the Digits of π Here's another example. The question seems a little arbitrary, but the answer is quite extraordinary. Consider the two balls shown in the figure. The rightmost ball has mass m. The leftmost ball is much heavier: it has the rather strange mass M = 16 × 100^N × m (Equation 4.32) where N is an integer."
Another photo of part of a page of the textbook: "We start with a particularly simple example. Consider a particle travelling with velocity u that collides with a second, stationary particle of the same mass. What happens? After the collision, the two particles have velocities v_1 and v_2. Even without knowing anything else about the interaction, there is a pleasing, simple result that we can derive. Conservation of energy tells us (1/2)mu^2 = (1/2)mv_1^2 + (1/2)mv_2^2 (Equation 4.26) while the conservation of momentum reads mu = mv_1 + mv_2 (Equation 4.27) Squaring this second equation, and comparing to the first, we learn that the cross-term on the right-hand side must vanish. This tells us that v_1 · v_2 = 0 (Equation 4.28) In other words, either one of the particles is stationary, or the two particles scatter at right-angles."
Another textbook photo: "You might sometimes read that there are forces that do not obey Newton's third law, either in weak or strong form. The magnetic force between particles is sometimes hailed as a culprit. One charged, moving particle induces a magnetic field that affects the motion of another. But the second does not reciprocate in the same way. In fact, a closer look shows that these "violations" of the third law are kind of fake because they ignore important properties of the electric and magnetic fields themselves, like the fact these fields can carry angular momentum. At heart, these cheap counterexamples are little different from an underwater swimmer who can twist and turn, seemingly violating the conservation of momentum and angular momentum, until you realise the the water itself carries these properties too."
Another photo of part of a page of the textbook: "Newton's third law tells us that F_ab = -F_ba, which allows us to write Σ_a Σ_a≠b x_a * F_ab = Σ_a<b (x_a - x_b) * F_ab (Equation 4.14) There's no reason that this has to vanish. But it does vanish if we require one further property of the interaction force between particles. We ask that the force F_ab between the a'th and b'th particle is parallel to the line (x_a - x_b) joining the two particles. This is sometimes elevated to a strong form of Newton's third law: - N3 Revisited Again: F_ab = -F_ba and is parallel to (x_a - x_b) In situations where this strong form of Newton's third law holds, the change in total angular momentum is again due only to external forces, dL/dt = τ (Equation 4.15) Both the gravitational (4.3) and electrostatic (4.5) forces obey the strong form of Newton's third law."
Photo of part of the textbook. It reads: "A Last Example: Rowing Another classic demonstration of the power of dimensional analysis shows how the speed of a rowing boat depends on the number of rowers. A boat traveling at speed v, with cross-sectional area A submerged in the water, experiences a quadratic friction F_drag ~ v^2 A (Equation 3.15) (On dimensional grounds, we should have F_drag ~ ρv^2 A where ρ is the density of water. But the density ρ will not play a role in the story and so we choose to drop it.) The power needed to overcome this drag force is then P = F_drag v ~ v^3 A (Equation 3.16) By Archimedes' principle, the displayed water volume increases linearly with mass. We'll assume that the weight of the boat itself is negligible and the weight" (end of page)

Another photo of part of the book: "BETA: Not 'guesswork' this time, but insight! TEACHER: I abhor your pretentious 'insight'."
A photo of part of a page in the book in the quoted post. It contains this footnote: "9. Cauchy thought that the instruction to find at each stage a triangle which can be removed either by removing two edges and a vertex or one edge can be trivially carried out for any polyhedron ([1813a], p. 79). This is connected with his inability to imagine a polyhedron that is not homeomorphic with the sphere." Incredible burn.
