University of Jyväskylä Physics Master’s Thesis Guide: FYSS9490, Seminar, Maturity, Supervision and Vasara

Start with the current Physics thesis map

The current University of Jyväskylä Physics master’s programme is controlled by the PHYMP2024 study structure for the 2024-2028 curriculum. The programme is an English-language Master of Science degree with a nominal 120 ECTS scope. For thesis planning, the most important common package is simple: FYSS9489 Master’s Seminar is 3 ECTS and Pass/Fail, FYSS9490 MSc Thesis is 30 ECTS and graded 0-5, and FYSS9495 Maturity Test is 0 ECTS and Pass/Fail. These three objects appear in all four current Physics specialisations, but the research content and methods are not identical across the specialisations.

1. Confirm PHYMP2024 and your specialisation first

Before choosing a topic, check that your active Sisu structure is PHYMP2024 and identify your specialisation. The four current options are Particle and Quark Matter Physics and Cosmology; Nuclear Physics, Nuclear Astrophysics, and Radiation Applications; Physics of Quantum Materials; and Physics Applications in Technology and Society. This matters because the thesis administration is shared but your advanced studies, research environment, technical methods and likely supervisor network depend strongly on the specialisation. A thesis topic copied from another Physics route can therefore be administratively possible but academically poorly aligned with your own studies.

2. Do not confuse the 30 ECTS thesis with the 3 ECTS seminar

FYSS9490 is the thesis itself and it is exactly 30 ECTS. FYSS9489 is a separate 3 ECTS Master’s Seminar. The seminar supports the thesis process by helping students select a topic, locate a supervisor, understand assessment criteria, build a realistic schedule and communicate research. It does not increase the thesis course to 33 ECTS. Keeping these objects separate is important when you calculate degree credits, plan enrolment, describe your thesis workload or explain the programme to an employer or external supervisor.

3. Use FYSS9489 to establish the project before the intensive thesis phase

The Master’s Seminar is not just a presentation course. Its learning outcomes include choosing a thesis topic, finding a supervisor, setting goals and drafting a schedule with meaningful checkpoints. It also introduces the department’s thesis assessment process and the student’s rights and obligations. The primary completion route includes assignments, participation and a public scientific presentation at the Department of Physics. Treat the seminar as a project-definition stage: by the end, you should know what question you are solving, who is supervising it, what the main milestones are and what evidence will show that the project is progressing.

4. Treat 30 ECTS as a real scope limit

The Department of Physics guidance connects the 30 ECTS thesis with approximately 810 hours of work, roughly six months of full-time effort. This is useful as a planning constraint. A master’s project should be scientifically meaningful, but it should not be designed as an open-ended doctoral project. If the research question expands every time new results appear, the work can easily exceed the intended degree scope. Agree a core deliverable with the supervisor, identify optional extensions separately, and use the supervision agreement to record a realistic completion date and checkpoints.

5. Start with one research problem, not a technology shopping list

Physics projects often provide access to attractive instruments, simulations, accelerators, detectors, numerical packages or materials systems. The existence of those tools is not itself a research question. Begin by defining the physical phenomenon or applied problem, the specific knowledge gap and the quantity or relationship that must be established. Only then choose measurements, calculations, simulations or theoretical tools. This order makes the methods section defensible because each method has a reason for being there. It also makes it easier to remove unnecessary work when the project needs to be narrowed.

6. Methods depend on the specialisation and research question

There is no programme-wide rule that every Physics thesis must be experimental, computational or theoretical. Particle and quark-matter work may be theoretical, computational or experimental. Nuclear and radiation-related projects can involve experiments, accelerators, modelling, detectors or theoretical analysis. Quantum-material projects may combine condensed-matter theory, computation, material characterisation or experiments. Physics Applications in Technology and Society is particularly broad and may include measurement, control, modelling, medical applications or other applied directions. Your method should therefore be justified by the question and approved project design, not by a generic idea of what a physics thesis “should” look like.

7. Find the responsible supervisor before locking the design

JYU’s current thesis guidance says a thesis can have several supervisors, but the responsible supervisor must be employed by the University of Jyväskylä and have a doctoral degree. This person is important because the responsible supervisor anchors the project inside the university’s academic and assessment system. An external company specialist, laboratory expert or doctoral researcher can contribute important day-to-day expertise, but this does not remove the responsible-supervisor requirement. Discuss the topic, scope, schedule, guidance frequency, data situation and expected assessment level with the responsible supervisor before the research design becomes difficult to change.

8. Make the supervision agreement operational, not ceremonial

The Physics supervision agreement is valuable only if it contains decisions that can guide the work. It should identify the responsible supervisor and other supervisors, record the expected difficulty and scope, give a justified schedule and establish supervision practices and checkpoints. The department also links schedule performance to the timetable recorded in the agreement unless the timetable is formally updated. Therefore, if experimental access is delayed, a simulation pipeline fails, external data arrive late or the project scope changes, update the plan rather than silently carrying an obsolete schedule into the final assessment.

9. Plan safety before project work begins

The department supervision material includes safety orientation as part of thesis planning. The exact requirement depends on the project. A theoretical calculation may have little laboratory risk, while accelerator, radiation, electrical, cryogenic, laser, vacuum, chemical or medical-technology work can require specific training and permissions. Do not copy safety procedures from another student merely because both projects are in Physics. Ask what facilities, hazards, data systems and access rights your own project uses, complete the required orientation before independent work, and document the relevant safety constraints in your project plan when they affect methods or scheduling.

10. Decide early whether the thesis is monograph, pair work or article based

Department guidance recognises a traditional monograph, a jointly written thesis and an article-based route with an accompanying introduction or literature-review component. Pair work and article theses require special care because the student’s own contribution must be independently visible and assessable. If two students share a project, divide responsibilities at the beginning and preserve evidence of individual analysis and writing. For an article-based thesis, clarify publication status, authorship, the student’s writing contribution and what contextual text is required for the degree submission before assuming that a manuscript alone will satisfy the thesis requirement.

11. Build a literature review that explains the physics of the problem

A strong Physics literature review is not a long catalogue of papers. It should explain the theoretical framework, the state of the relevant measurements or calculations, the unresolved issue and why the chosen research question is worth answering. Organise literature around concepts and competing explanations rather than around author names. When a method is central, review its validity, calibration, assumptions and known limitations as well as its applications. This structure makes the later discussion easier because the thesis can compare its own result with a clearly established scientific baseline instead of adding references only after the analysis is complete.

12. Separate research design from technical execution

The thesis course expects research design as well as implementation. A technically sophisticated workflow can still be weak research if it does not explain what evidence would answer the question. Write down the independent and dependent quantities, controls or comparison cases, uncertainty sources, inclusion rules and decision criteria before large-scale data collection or computation. For simulation or theory, specify model assumptions and parameter choices. For experiments, specify calibration and reproducibility checks. For applied projects, distinguish performance targets from scientific claims. These decisions make later interpretation more transparent and reduce the risk of choosing conclusions after seeing the results.

13. Treat uncertainty and validation as part of the result

In physics, a numerical value without a defensible uncertainty or validation argument is often incomplete. Decide what kinds of uncertainty matter in your project: statistical variation, systematic effects, model dependence, calibration error, finite resolution, numerical convergence, sampling limitations or external-data uncertainty. Use controls, benchmark cases, independent checks or sensitivity analysis where appropriate. The assessment matrix asks whether methods and theories are used appropriately and whether results are analysed reliably. A thesis that openly explains limitations and validation can therefore be stronger than one that presents apparently precise results without showing how trustworthy they are.

14. Keep data management proportional to the actual project

JYU data-management guidance applies to data that you collect, generate, process or receive. A Physics project may create large detector files, simulation outputs, code, images, laboratory logs or processed datasets. Plan where these materials are stored, who can access them, how versions are identified, what metadata or README information is needed and what can be preserved or shared after the thesis. If no personal data are involved, do not invent GDPR procedures that do not apply. If personal data are involved, for example in some medical or human-facing applied projects, follow the university’s personal-data requirements from the planning stage.

15. Ethical review is conditional, not automatic

The existence of JYU’s Human Sciences Ethics Committee does not mean every Physics thesis needs a human-sciences ethics statement. Many theoretical, materials, detector, accelerator or simulation projects fall outside that route. Ethical review becomes relevant when the design meets the university’s applicable human-sciences criteria or other regulated conditions. Discuss this before data collection if people, identifiable personal data, sensitive interventions or similar elements are involved. The safe rule is to assess applicability early and document the decision, not to state either that all Physics theses need ethical review or that Physics research can never need it.

16. Use AI only within current JYU rules and preserve authorship responsibility

AI tools may support limited tasks when current JYU and course instructions permit them, but responsibility for the thesis remains with the student. Do not use a generative system as an invisible author of scientific reasoning, data interpretation, code you cannot explain or references you have not verified. If AI is used for permitted language, coding or idea-support tasks, follow the current disclosure and course guidance and verify every scientific statement independently. In a Physics thesis especially, fabricated citations, invented equations, silent code errors or altered numerical outputs can undermine both research integrity and reproducibility.

17. Write the methods so another physicist can understand what was actually done

The methods section should be specific enough for an informed reader to understand the experimental, computational or theoretical workflow. Name the relevant apparatus, data source, model, software or numerical approach when this is academically necessary, but avoid turning the section into an equipment inventory. Explain calibration, preprocessing, parameter choices, boundary conditions, selection criteria and analysis sequence. If established methods are used, cite their original or authoritative descriptions. If you modified a method, explain the modification and why it was needed. The goal is traceability from research question to evidence, not maximum technical vocabulary.

18. Keep code, calculations and figures reproducible

For computational work, preserve the exact code version, input parameters, environment information and data-processing steps needed to reproduce the reported result as far as the project permits. For analytical calculations, show enough intermediate reasoning that assumptions and approximations can be checked. For experiments, keep analysis scripts linked to raw or processed data with clear identifiers. Figures should be generated from controlled data and code where possible, not manually edited in ways that obscure provenance. Reproducibility practices also make supervisor review faster because unexpected results can be traced instead of reconstructed from memory.

19. Use the assessment matrix while drafting, not only at the end

The Department of Physics assessment matrix evaluates more than the final numerical result. It considers how the research assignment is framed, how research is conducted, how results are analysed, the quality and coherence of the scientific text, referencing, presentation and layout, the title and abstract, independence and progress against the schedule. Use these categories as a drafting checklist. A technically correct project can lose quality if the research question is vague, literature is disconnected, figures are unreadable or conclusions exceed the evidence. Conversely, strong structure and transparent reasoning help reviewers see the actual scientific contribution.

20. Do not calculate the thesis grade as a simple average yourself

The Physics matrix provides descriptive anchors for grades 5, 3 and 1 and indicates that grades 4 and 2 fall between adjacent levels. The final grade is a holistic academic judgement, not a spreadsheet average of category scores. Use the matrix to identify weaknesses, but do not assume that improving one visual element mathematically compensates for a fundamental problem in research design or scientific validity. The most useful approach is to ask whether the thesis consistently meets the descriptors for framing, method, analysis, writing and independence at the level you are targeting.

21. Prepare a thesis structure that follows scientific logic

A typical Physics thesis will usually need a focused introduction, the necessary theoretical or technical background, a clear methods or model section, results, discussion and conclusions, with references and appropriate appendices. The exact chapter names can vary because theoretical, experimental and applied projects tell different scientific stories. Do not force a laboratory-style structure onto a purely theoretical thesis or hide an important validation study in an appendix merely to match somebody else’s template. The structure should make it easy to follow the chain from problem to method, evidence, interpretation and answer.

22. Make figures carry scientific information

Figures should answer a question rather than decorate the thesis. Label axes with quantities and units, explain symbols and uncertainty, use readable text and state important analysis conditions in the caption or surrounding text. If a plot compares theory and data, make the comparison conditions explicit. If an image has been processed, explain the processing relevant to interpretation. Avoid presenting dozens of nearly identical plots when a summary figure or table would communicate the pattern more clearly. The assessment matrix explicitly includes visual presentation, but scientific clarity is more important than visual complexity.

23. Keep results and interpretation logically distinct

A result section should establish what the data, calculation or model actually produced. The discussion should explain what that result means, how robust it is, how it compares with prior work and what limitations affect the interpretation. In some Physics theses these sections are combined, which is acceptable if the logic remains clear. Avoid presenting a model-dependent interpretation as a direct measurement, or describing an observed correlation as a causal mechanism without supporting evidence. Explicitly separating observation, inference and speculation makes the thesis more scientifically credible.

24. Use conclusions to answer the research question

The conclusion should return to the problem stated at the beginning and give the strongest answer that the evidence supports. Summarise the main quantitative or qualitative findings, state the important uncertainty or boundary, and explain the scientific or applied significance without repeating the whole discussion. Future work is useful when it follows logically from unresolved issues, not as a list of everything that could ever be studied. A precise limited conclusion is academically stronger than a broad claim that the thesis data cannot justify.

25. Complete the maturity test through FYSS9495

FYSS9495 is a separate 0 ECTS Pass/Fail requirement even though in many cases no separate long examination is needed. In an English-medium programme, the maturity test is normally in English. If the required Finnish or Swedish school-language proficiency has already been demonstrated in an earlier maturity test, the master’s thesis abstract can normally be accepted as the maturity test. If that proficiency still has to be demonstrated, an examination route in the relevant school language applies. Check your own language history rather than copying another student’s maturity procedure.

26. Register correctly before final submission

Current Physics instructions say students should register for the FYSS9490 thesis and FYSS9495 maturity-test implementations in Sisu to obtain access to the relevant Moodle workflow. Do this early enough that access problems do not appear at the final deadline. Implementation dates and enrolment windows are cycle-sensitive, so use the active Sisu and Study Guide information rather than dates copied from an older guide. Course codes are stable evidence for the current 2024-2028 structure, but a particular Moodle opening date or enrolment deadline should always be rechecked.

27. Run the final Turnitin check in the Physics Moodle route

Physics-specific submission instructions direct the final thesis to plagiarism detection in the FYSS9490 Moodle workspace. Use the version that you and the supervisor consider ready for final assessment. Turnitin is a research-integrity control, not a mechanical percentage target. A similarity report can include legitimate quotations, references, formulas and standard terminology, while a low percentage does not prove originality. Review meaningful matches with the supervisor, correct citation or attribution problems, and keep the final assessed version stable after the final check.

28. Submit the final accessible PDF/A through the current Vasara process

JYU’s current university-wide guidance says the master’s thesis submission, review and archiving process is electronic through Vasara. Before submission, confirm with the supervisor that the work is final, complete the required Turnitin step and save an accessible PDF/A. The current process automatically stores a thesis submitted through Vasara in JYX, so an older instruction that implies a separate later manual JYX deposit should not be treated as the current default workflow. Follow the live Vasara instructions at the time of submission because system details can change.

29. Keep confidential material out of the public thesis

A JYU master’s thesis is a public document. This is particularly important for applied projects with companies, medical settings, proprietary devices or restricted datasets. If confidential material is needed for the research, agree early how it will be handled as background material and how the public thesis will describe the work without disclosing protected information. Do not promise a sponsor that the thesis itself can simply be made confidential. The public-document rule and university publishing guidance should be discussed before signing external project arrangements or accepting data that cannot be described appropriately.

30. Remember that copyright remains with the thesis author

Current JYU publishing guidance explicitly states that the author retains copyright and that storing the thesis in JYX does not remove it. The author is also responsible for having the right to publish included figures, tables, photographs or other third-party material. Therefore, do not copy publisher figures into the thesis merely because they are scientifically relevant. Use your own figure where appropriate, seek permission when necessary, or rely on a properly cited description. A Creative Commons option may be available for the thesis, but the choice of licence is separate from the university’s public-document requirement.

31. Understand the two-reviewer assessment process

Department guidance describes a two-reviewer process after the final originality-check stage. The reviewers evaluate the thesis against the Physics criteria and prepare their assessment within the defined review period. The student then has a formal opportunity to consider the assessment before the grade is finalised. Treat this as an academic assessment process, not an informal supervisor decision. Before submission, use the same department criteria yourself and resolve obvious weaknesses while revision is still possible. Once a thesis enters final assessment, procedural rights exist, but they should not be used as a substitute for careful pre-submission review.

32. Know the right to interrupt, respond and seek rectification

JYU and Department of Physics rules provide procedural protections if a student believes the thesis is not ready for the proposed assessment or disagrees with the evaluation. The Physics guidance allows interruption of the assessment once before final grading under the applicable conditions, and a sufficiently revised thesis can later be resubmitted. It also describes a response route that can lead to an additional reviewer. After a final decision, university regulations provide a rectification route. These procedures are time-sensitive, so if a dispute occurs, consult the current decision notice and degree regulations rather than relying on remembered deadlines.

33. Plan backwards from graduation, but use live deadlines

The safest way to plan completion is to work backwards from the intended graduation date and include time for supervisor review, final revisions, Turnitin, submission, examiner work, the student’s response period, maturity completion and administrative registration. Do not assume the examination itself will happen instantly after submission. Department guidance gives reviewers a defined review period, and holidays or exceptional workloads can affect practical timing. Because semester-specific deadlines change, use current faculty and Sisu notices for the actual date and keep a margin rather than targeting the latest possible submission day.

34. A compact Physics thesis workflow

A practical sequence is: confirm PHYMP2024 and specialisation; complete or engage with FYSS9489; select a bounded problem and responsible supervisor; sign a meaningful supervision agreement; confirm safety, data and ethics requirements; review the literature; finalise method and validation logic; conduct the research with versioned records; analyse uncertainty and limitations; draft around the department assessment criteria; present and revise; confirm the correct FYSS9495 maturity route; register FYSS9490/FYSS9495; complete the final Turnitin check; create the accessible PDF/A; submit through current Vasara; review the examiner statement and use procedural rights if necessary; then verify that the thesis and credits are correctly recorded.

35. Final verification checklist for the current programme

Before treating the thesis as finished, verify five things against live JYU systems: your study structure and specialisation are still correct; FYSS9489, FYSS9490 and FYSS9495 are the applicable objects in your plan; the supervisor has accepted the final version for submission; the final file has passed the required originality and accessibility steps; and Vasara/Sisu show the required assessment and maturity workflow. The academic rules in this guide were verified against the current 2026 Study Guide and JYU guidance for the 2024-2028 curriculum, but enrolment dates, Moodle implementations, administrative contacts and system screens are operational details that should always be checked again when you act.
