Discussion Overview
The discussion revolves around whether Einstein's field equations can explain the phenomenon of a locomotive sinking into the sand in Bolivia. Participants explore the implications of these equations in relation to the scenario presented.
Discussion Character
- Debate/contested
Main Points Raised
- One participant asserts that the Einstein field equations are responsible for the locomotive sinking.
- Another participant shares a personal anecdote about a historical steam engine and humorously suggests a nonsensical equation (H2O = MC2) to provoke thought.
- A participant discusses methods for stabilizing rust on a historical artifact, indicating a practical application of knowledge unrelated to the main question.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the applicability of Einstein's equations to the sinking locomotive, with differing views presented without resolution.
Contextual Notes
The discussion includes personal anecdotes and practical advice that diverge from the theoretical focus, highlighting a mix of exploratory reasoning and technical discussion.
Who May Find This Useful
Individuals interested in the intersection of theoretical physics and practical applications, as well as those curious about historical engineering artifacts.

They are responsible for it.
The paint makes the locomotive heavier.
I would not hide the obvious answer in a spoiler.

What an idea you have just triggered.
Last month I purchased a rusted garden ornament from a scrap dealer. It was an historical Robey & Co portable steam engine from the 1880s. I will stabilise what remains and paint it to stop to rust.
What would an appropriate equation be? H2O = MC2 Will that make them think?

Probably you know of this stuff, but i'll mention it just in case.Baluncore said:
i use a phosphoric acid based stabilizer with some chromates in it, Hardware and home supply stores have it under various brand names.. around here it's "Ospho" . It changes rust into a more stable black material.
It also etches aluminum so paint will stick. I used it on that pink boat with good results.
