Bring a question. Develop an argument.
I welcome collaboration with experts in physics, mathematics and philosophy. A precise question, a worked model or a thoughtful interpretation can give us a useful place to begin.
Use the guide below to prepare a research note. You can copy it or download it, then contact Mohamed Haj Yousef when you are ready to share it.
Give the conversation a clear starting point
A useful contribution begins with a statement another reader can locate. Cite the article, equation, paper DOI or book chapter you want to discuss. If the issue concerns a broader interpretation, name the particular claim and explain the sense in which you understand it. A quotation of a few words or a precise paraphrase can make a long exchange much easier to follow.
State the question before the background. For example: “Does the rank argument still hold when channels need not come in opposite pairs?” gives a collaborator a concrete problem. You can then explain why that assumption matters to your understanding of spatial dimension.
You do not need to endorse every part of the framework to develop a useful question. Careful criticism, alternative constructions and explicit comparisons help identify what an argument establishes and how it could become stronger.
Show the part of the argument that does the work
For a derivation, identify the premises and keep your variables consistent. State whether a result is exact in a finite model, conditional on an approximation, or a proposal for a physical identification. Include the calculation that links the assumptions to the conclusion, especially where a normalization, quotient, limit or choice of readout enters.
A counterexample is especially useful when it satisfies the stated assumptions. Describe the allowed model class, build a member of that class, and demonstrate the failure of the proposed conclusion. If your example changes an assumption, explain that change: it may show how far a claim can be generalized even when it does not contradict its original form.
For numerical work, record the equations, parameter values, units and initial or boundary conditions. Supply enough detail to reproduce the result. A plot supports an argument when the reader can see what was computed and why the chosen quantity answers the question.
Make philosophical and historical distinctions explicit
Questions about source, identity, causation, existence and time are central to the project. A philosophical contribution can clarify the logical form of a claim, compare interpretations or examine whether a proposed physical construction supports its intended meaning.
Keep the relevant levels of explanation visible. An operational observer may be a system capable of retaining a record; a claim about conscious experience asks for a further account. Similarly, a physical vacuum is defined within a theory, while a philosophical question about nothingness can challenge the existence of the theory’s whole structure.
For historical texts, give the author, work, edition or translation, and a passage reference where possible. Explain how you are using the passage: as historical evidence, a conceptual comparison or a source of inspiration for a modern model. A careful distinction can open a productive dialogue between the history of ideas and contemporary physics.
Propose a collaboration that can begin
I welcome collaboration with experts in physics, mathematics and philosophy. Tell me which question you would like to develop, the expertise or tools you can bring, and what a useful first result would look like. A finite construction, a proof of a missing implication, a comparison with an established formalism or a focused philosophical argument can provide a workable first project.
A short proposal can include:
- The research question and the source that motivates it.
- Your field, relevant experience and an optional profile or publication link.
- The part you would like to contribute: formulation, proof, model building, computation, interpretation or joint writing.
- A concrete first deliverable and the main uncertainty you would like to resolve together.
There is no need to predict a whole project’s outcome in advance. A clear account of what can be examined next is more useful than a promise of a final theory.
Prepare your contribution
A structured research note
Your writing stays in this page until you choose to copy, download or save a draft on this device. Use the contact page to share the finished note.
Identify the exact statement, equation or interpretation you want to examine.
State the setting, variables, allowed choices and any physical identifications.
Give the main argument, model, counterexample or collaboration idea. Explain what your expertise would add.
Describe a proof, calculation, source passage, code example or measurable comparison.
Include article URLs, paper DOIs, book chapters or page and equation numbers.
A brief introduction and a research profile or relevant publication can help begin a collaboration.
