Angular motion and minimum speed

Translate an observed angular speed into transverse speed under explicit distance assumptions.

What does a real call return?

At 10 km, an angular speed of 1° per second requires at least 628 km/h of transverse motion. The claimed 600 km/h returned the verdict contredit (contradicted).

Recorded on 2 November 2026 through the public MCP endpoint, service release 0.17.1. Inputs and full responses, response SHA-256 c0862dc571d6…. Verdict values are the literal values the tool returns. Run the same inputs yourself to compare; elapsed times vary, and a new release may change the figures.

Checked against

Radians-per-second times distance, with independently hand-calculated speed and limiting-distance anchors.

Recorded on release 0.16.1. These checks cover the listed cases, not every input. Evidence cards.

How it works

The calculation relates angular motion to transverse speed through v = ω × distance, with the angular rate converted to radians. A claimed speed can then be compared with the speed required at a claimed distance.

Inputs and units

Provide angular speed in degrees per second and distance or speed hypotheses. The tool exposes bounded parameter ranges through tools/list.

What the result contains

Speed-distance comparisons and profiles help an assistant explain what the observation would imply under each hypothesis.

Execution and availability

ScoreCompute exposes this tool through MCP Streamable HTTP. Rust computation runs on a connected worker; the public website and MCP gateway run separately. Among these 22 scientific tools, CUDA is implemented for simulate_pi; the other scientific engines run on CPU. The separate contributor network runs two compiled public workloads: a π estimate and fixed synthetic schedule probes. Requests are bounded and concurrent work may be refused when capacity is occupied.

Record inputs, assumptions and returned provenance when sharing a result. The public observatory displays software client names and tool activity, without publishing calculation arguments or results.
