Derifield Physical Sciences Research. Independent research in physics, electronics, chemistry, astronomy, and sustainability.
The practice works across five areas. The common method is measurement: define the question, build the instrument or pipeline, record the data and the uncertainty, and publish a result that another person can check.
Some projects are computational, some are instrumental, and some are field measurements. The area pages describe the questions, the current work, the method, and the directions that come next.
Measurement and models
Measurement, instrumentation, and models for systems where the uncertainty budget matters as much as the headline number.
Instruments and readout
Sensors, readout, embedded control, and the calibration chain that turns a physical quantity into a recorded number.
Analysis and materials
Analytical measurement, spectroscopy, materials, and the chemistry of small samples and real matrices.
Time domain and archives
Transit timing, archive photometry, and the instrumentation that connects a photon count to a physical model.
Energy and environment
Energy, materials, and environmental measurement, with the same rule: state the boundary, the data, and the uncertainty.
| Project | Area | Status | Record |
|---|---|---|---|
| TESS transit timing | Astronomy | Working project: selection rule, synthetic recovery, two real single-transit fits, full-sector cross-check | result note, manuscript draft |
Projects in the other areas are in development. Their records will be listed here when they are released. The publications page carries papers and preprints, and the notes archive carries working notes.
