MJ PHYSICS ENGINEERING / FOOTBALL
Love the game.
Explore the physics.
Bring one play. Mark what you can see. Follow the math from movement to a clearer question.

ONE PLAY. ONE QUESTION.
A MODEL WE CAN EXAMINE.

CLIP → MEASUREMENT
Load a short clip, mark the play window, calibrate the field, and plot player positions. Read and download the resulting physics report.
Manual tracking. No automatic scheme recognition. YouTube review uses manually entered coordinates.

DIAGRAM → UNDERSTANDING
Begin with Mesh and Cover 3 Sky: two documented coaching concepts, with newly drawn alignments, complete assignments, and a clear physics question.
Coaching sources are linked on each page. The larger historical catalog stays out of this edition pending review.

CONTEXT → REVIEW
The broader analysis project connects film review, football context, source evidence, and coaching questions. Its papers explain the design and boundaries.
The historical analyst workspace and its private game records are separate from this public lab.
Read the analysis papers →A SIMPLE WAY IN
Observe. Measure. Explain.
01 / Start with the filmChoose a visible movement and describe it without assuming the player's assignment.
02 / Name the modelState the coordinates, clock, units, assumptions, and classical physics relationship.
03 / Keep the uncertaintyCompare what the model predicts with what the marked frames support.
02 / The football paper spectrum
Different colors. Connected ideas.
The three football projects, each articulated through 12 separate color papers. Start with Teal for IF / HOW / THEN and Purple for typed expression.
These 36 documentary papers retain their stated source limitations. Gold and Indigo are new reconstructions under recovered overview rules. White papers are excluded; a Green source sequence was not recovered.

Pink
Gateway, lifecycle and evidence

Brown
Observational lifecycle

Blue
Reference briefs

Purple
Syntax and typed expression

Teal
IF / HOW / THEN logic

Yellow
Visual and measurement blueprints

Orange
Potential IP pathways

Grey
Terminology and reconciliation

Angel
Gate, sentinel and audit

Rainbow

PHYSICS QB / IN DEVELOPMENT
Football is the conversation.
Physics gives us a way to ask.
Our first episode explores why a quarterback throws toward a receiver's future position. Begin with classical motion, draw the play, and test the assumptions together.
