Abstract

fetched live from OpenAlex

Abstract. Frisbees are a common source of entertainment and sport, although the physics behind these flying discs is often taken for granted. Frisbees operate under two main physical concepts, aerodynamic lift and gyroscopic stability. When flying through the air, a Frisbee can be viewed as a wing, with Bernoulli’s Principle governing the magnitude of the lift force which keeps it aloft. The various forces applied are not centered on the disc though, so to keep the Frisbee from flipping over a high angular momentum is needed. This angular momentum resists the torque caused by the various forces. A computer program using the numerical technique Euler’s method was written to model the trajectory of a flying Frisbee. Different trials were made with different angles of attack and the various distances and heights that the Frisbee reached were observed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
