Discussion Overview

The discussion centers on the 1919 observations related to Eddington's measurements of light deflection during a solar eclipse, specifically examining the experimental margin of error and its implications for distinguishing between Newtonian and Einsteinian predictions. The scope includes historical analysis and the reliability of early experimental methods in the context of relativity.

Discussion Character

  • Debate/contested
  • Historical

Main Points Raised

  • One participant questions whether the experimental margin of error was sufficiently large to differentiate between Newton's and Einstein's theories.
  • Another participant references a relevant article and notes that modern re-measurements of the plates confirmed Eddington and Einstein's predictions.
  • A different participant highlights that during Eddington's time, it was uncommon to report experimental errors, suggesting that modern experiments might provide clearer insights.
  • Some participants speculate that the experimental margin of error likely hindered the ability to discriminate between the two theories, while also noting the sensationalism in media coverage at the time.
  • There is a suggestion that Eddington's reputation may have influenced the acceptance of the results without thorough scrutiny.

Areas of Agreement / Disagreement

Participants express differing views on the adequacy of the experimental margin of error and its impact on the acceptance of Eddington's results. There is no consensus on whether the margin of error was significant enough to prevent discrimination between the two theories.

Contextual Notes

Limitations include the historical context of experimental error reporting and the potential influence of Eddington's prestige on the acceptance of the results, which may affect interpretations of the data.

TL;DR
Could Eddington distinguish Newton from Einstein?
Looking for a discussion of the 1919 observations I tend to find 1. Statements that Ed & Co. were right to thro out certain data and 2. Assurances that in any case relativity has been confirmed subsequently. But what I want to know is: was the experimental margin of error so large as to prevent discrimination between Newton and Einstein?

Unfortunately, in Eddington's day it was not common to report experimental errors. So you may need to look at more modern experiments, after the practice became common among the scientific community.

Probably. But, it gave the newspapers a great headline!

And I think it's fair to say that Eddington's prestige precluded any real review of the results at the time. They were just accepted.
