Science in history: reconstruct what a reading measured
A larger number can record a changed scale rather than a changed phenomenon. Reconstruct units, instruments and recording conventions before writing a story of discovery or progress.

Scope and responsibility
The numerical archive is invented, not a historical quotation or experiment attributed to a real scientist. Teich’s European Scientific Revolution focus is narrower than a global history of science, technology and medicine.
Choose your starting point
Begin with an open historical argument
Use Teich to ask how inquiry and its social setting are connected.
Build broader modern context
Use Bowler/Morus to connect scientific changes with institutions and society across topics.
Study experimental authority
Use Shapin/Schaffer for a sustained account of how experimental knowledge and its credibility are established.

The Scientific Revolution Revisited
Mikuláš Teich · 2015
Free focused interpretation
- Choose it when
- You have early-modern context and want an argument, not only a chronology.
- Use another route when
- You need an all-period global survey or technical physics instruction.
- Selected reading
- Read the introduction and a selected chapter alongside a chronology of the period discussed.
- Limits and trade-offs
- A historically specific interpretation does not establish a universal single cause of science.
Try before choosing
Separate an actor’s recorded category from a later historian’s description of it.

Making Modern Science
Peter J. Bowler; Iwan Rhys Morus · Edition: 2 · 2020
Broader survey
- Choose it when
- You need an entry to modern-science episodes and social contexts.
- Use another route when
- You only need one close case or a first experimental methods manual.
- Selected reading
- Use the second edition’s discussions of scientific change, institutions and public relations with science as a thematic route.
- Limits and trade-offs
- A survey’s synthesis and an original laboratory record have different evidential roles.
Try before choosing
Make an observation–instrument–recording–interpretation chain for the invented packet.

Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life
Steven Shapin; Simon Schaffer · 2017
Experimental-life study
- Choose it when
- You can follow early-modern history and want to examine evidence and credibility.
- Use another route when
- You need a general survey or a current account of laboratory accuracy.
- Selected reading
- Read the discussions of experiment, witnessing and disputes over knowledge, using the selected edition.
- Limits and trade-offs
- Social authority and mathematical conversion are related questions, but neither substitutes for the other.
Try before choosing
Explain why calibration can defeat a numerical progress claim without settling who trusted the instrument.
Check your work: Identify both the conversion result and a separate missing reception record.
Check your preparation
What mathematics is needed?
A linear conversion and subtraction. The packet supplies its calibration domain and exactness; this is not a claim about actual historical precision.
Does an instrument’s new scale prove improvement?
No. Accuracy, repeatability, usability and authority require different evidence from an altered scale factor.
Can present knowledge correct every actor?
First establish what actors meant and could observe. A modern label is an analytical choice, not automatically their category.

-
Register the sources
Selected reading: History survey: evidence.
What to do: List each invented ledger, calibration and column heading.
Check your work: Keep a reported measurement distinct from a modern transcription.
-
Recover the old scale
Selected reading: Open argument with packet.
What to do: Use A’s two standards and stated linearity to derive r=2x+10.
Check your work: Retain the offset 10.
-
Recover the later scale
Selected reading: Survey with packet.
What to do: Derive B’s r=4x+6 and invert it.
Check your work: Both slope and zero differ.
-
Compare like quantities
Selected reading: Experimental-life route.
What to do: Convert raw readings before comparing.
Check your work: 30 versus 46 becomes 10 versus 10.
-
Change the column evidence
Selected reading: Follow-up with source register.
What to do: Recalculate when 46 is a converted x entry rather than raw r.
Check your work: The heading changes the role of the same numeral.
-
Write a historical claim
Selected reading: All three routes.
What to do: Separate measured change, instrument improvement and reception.
Check your work: Support only the claim the packet actually constrains.
Worked exercise
Two scales in an invented archive
In fictional year 70, instrument A’s raw scale has standards x=0→r=10 and x=10→r=30. In year 71, B has x=0→r=6 and x=10→r=46. The same reference quantity x is measured in unit U; both scales are stipulated exact and linear for 0≤x≤50. The observation ledgers explicitly label A’s entry 30 and B’s entry 46 as raw r. Did the measured quantity increase, and is B thereby more accurate?
Assumptions
All standards and headings are complete invented records. The underlying quantity is comparable across occasions, with no measurement error within the stipulated model. Instrument operation and real historical practice are outside the packet.
- A’s slope is (30−10)/10=2, so r=2x+10 and x=(r−10)/2. Its observation gives x=10 U.
- B’s slope is (46−6)/10=4, so r=4x+6 and x=(r−6)/4. Its raw 46 also gives x=10 U.
- Raw readings rise by 16, but converted quantity changes by zero. Both instruments were stipulated exact, so no improvement in accuracy is demonstrated; no actual uncertainty comparison is supplied.
Answer and interpretation
The model’s measured quantity is unchanged at 10 U. A story of growth based only on 30→46 confuses scales; a story of superior accuracy needs evidence beyond a changed scale.
Test the result
Check both zero points. Dividing by slope alone would give 15 and 11.5 and manufacture a false difference.
Change an assumption
The later column was already converted
Correct the source description: B’s ledger column is explicitly labelled “x in U”, not raw r. Its 46 is already a converted quantity. A’s entry remains raw r=30; both calibration functions and exact linear domain 0–50 remain.
- A still converts to x=10 U. B now directly records x=46 U and must not be converted a second time.
- The comparable change is 46−10=36 U, rather than zero. B’s implied raw reading would be 4×46+6=190, within its stipulated calibration domain.
- The new heading changes the interpretation of the numeral, not merely the arithmetic. A measured increase now follows in the paper model, but superiority of the instrument and the cause of the increase still do not.
Answer and interpretation
The corrected packet supports an increase of 36 U. It still supplies no evidence of improved accuracy or a historical discovery’s social acceptance.
Test the result
State exactly which source premise changed. Keep original and corrected interpretations separate rather than selecting the more dramatic result.
Common mistakes
Raw figures become common units
Recover the scale and offset first.
New instrument means progress
Specify the dimension of improvement and its evidence.
Later categories become actors’ words
Distinguish modern interpretation from recorded vocabulary.
Before moving on
- Choose a focused argument, broad context or close study of experimental authority.
- Translate readings using complete calibration and heading evidence.
- Revise a historical claim when a recording convention changes.

Teich’s 2015 open book is CC BY 4.0 and examines European inquiry in social context.
- Bowler/Morus: Chicago second edition
Chicago identifies the 2020 second edition; a broad survey complements a specific source exercise.
- Shapin/Schaffer: selected Princeton paperback
The selected 2017 Princeton paperback is distinct from the original publication; no technical recipe is inferred from its historical argument.
