BeakerWise credits

This page names the work of others in BeakerWise (BeakerWise: The Real Science Lab): the files, the data, the curriculum text, the software and the voice model. It also names our own work. It is free to read, with no login.

• These third-party files keep their own licences. The store terms do not limit your rights under the licences of the third-party material listed here.
• The developer and publisher is dav3studios.
• The app names no exam board. Where a fact comes from an exam board's practical handbook, the app names the source "School practical handbooks". No exam board made, checked or approved BeakerWise.

Sources under CC BY that the app cites

The app ships no text from these pages. Two facts are written in our own words from them. Their quotes are kept in docs/fact_quotes.json, which is not exported.

The credits in the app

The app shows this text under Grown-ups > Credits (content/legal.json).

• Data. Atomic lines: NIST Atomic Spectra Database (ver. 5.12), Kramida, Ralchenko, Reader and NIST ASD Team, 2024. Thermophysical data: NIST Chemistry WebBook (SRD 69). Physical constants: CODATA 2022, NIST. Water and ice: IAPWS releases. Chemical data: PubChem and the Hazardous Substances Data Bank, US National Library of Medicine. Colour matching: nine single values of the CIE 1931 2-degree colour-matching functions, from CIE 2019, "Colour-matching functions of CIE 1931 standard colorimetric observer", doi:10.25039/CIE.DS.xvudnb9b, https://files.cie.co.at/Publications-datasets/CIE_xyz_1931_2deg.csv. One is the table row at 380 nm. The other eight are at the flame-line wavelengths: we worked them out between two rows of the table (linear interpolation). They are single measured values, cited as facts. The CIE table itself (CC BY-SA 4.0) is not copied into the app. sRGB conversion: W3C CSS Color 4. Teaching notes cited as sources: ChemBAM, "Chromatography of painkiller drugs", https://chembam.com/online-resources/a-level-resources/painkiller-chromatography/, and Science in School, "Colour, chlorophyll and chromatography" (2019), https://scienceinschool.org/article/2019/colour-chlorophyll-and-chromatography/.

• Curriculum. Contains public sector information licensed under the Open Government Licence v3.0, https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ (Department for Education: the National Curriculum in England and the GCSE subject content, https://www.gov.uk).

Changes: we chose the statements, gave them our own ids and joined the lines of each bulleted statement. The words are not changed.

• Fonts. Atkinson Hyperlegible by the Braille Institute of America and Andika by SIL International, SIL Open Font License 1.1, https://openfontlicense.org.
• Voice. Narration made with the Kokoro text-to-speech model (Apache 2.0).
• Your rights. These third-party files keep their own licences. The store terms do not limit your rights under the licences of the third-party material listed here.
• Software. Made with the Godot Engine (MIT licence), the Godot OpenXR Vendors plugin and the Godot Meta Toolkit (both MIT), with Meta's Platform SDK loader, the Khronos OpenXR loader (Apache 2.0), the LLVM libc++ library, and AndroidX and Kotlin libraries (Apache 2.0). Their licences ask for notices in every copy: see "Software notices" below.

The voice

Every spoken line is a recording that we made with a computer voice: the Kokoro-82M text-to-speech model (hexgrad, Apache License 2.0, https://github.com/hexgrad/kokoro/blob/main/LICENSE), voice bm_george. No person recorded the lines. The model itself is not in the app.

Fonts

Atkinson Hyperlegible by the Braille Institute of America, also as "Ux Reading" with a plain zero, and Andika by SIL International. Both are under the SIL Open Font License 1.1 (https://openfontlicense.org). The licence text of each font is in the app next to the font file.

Sources of the facts

The measured values in the app come from source pages, and the "How we know" card of each experiment names its sources. Our checking tool found a quote for each of these facts on its source page. Not every number is measured: 93 of the 104 experiments also use estimates or values chosen for the activity (for example the power of a warm plate). The app marks them: the label on each experiment says when some values are estimates, and the "How we know" card lists each estimate. We name these bodies and authors as sources only. They did not make, check or approve BeakerWise. The source names that the app shows:

Software in the app

The app is made with the Godot Engine and other software. Their licences ask for their notices in every copy. The full notices and licence texts are in the app, under Grown-ups > Credits > Software notices. The app reads Godot's notices from the engine itself, so they match the engine in the app.

The Godot Engine includes third-party parts under their own licences (MIT, Apache 2.0, BSD, zlib, MPL 2.0 and others). Godot lists each one, with its copyright and licence, in https://github.com/godotengine/godot/blob/4.7.2-stable/COPYRIGHT.txt.

Our own work

dav3studios wrote the app's own code: the BeakerWise scripts, the experiment models and our shared app engine (GDScript). dav3studios also made these files:

The engine's interface sounds are our own work too, made by computer program with no recordings.

Store art and trailer

These files are on the store page, not in the app. dav3studios made them from the app's own apparatus, scenes and screens.
