The conceptual foundations of physics have been under constant revision from the outset, and remain so today. Discussion of foundational issues has always been a major source of progress in science, on a par with empirical knowledge and mathematics. Examples include the debates on the nature of space and time involving Newton and later Einstein; on the nature of heat and of energy; on irreversibility and probability due to Boltzmann; on the nature of matter and measurement during the early days of quantum theory; on the meaning of renormalization, and many others. Today, insightful reflection on the conceptual structure utilized in our efforts to understand the physical world is of particular value, given the serious unsolved problems that are likely to demand, once again, modifications of the grammar of our scientific description of the physical world. The quantum properties of gravity, the nature of measurement in quantum mechanics, the primary source of irreversibility, the role of information in physics – all these are examples of questions about which science is still confused and whose solution may well demand more than skilled mathematics and new experiments. Foundations of Physics is a privileged forum for discussing such foundational issues, open to physicists, cosmologists, philosophers and mathematicians. It is devoted to the conceptual bases of the fundamental theories of physics and cosmology, to their logical, methodological, and philosophical premises. The journal welcomes papers on issues such as the foundations of special and general relativity, quantum theory, classical and quantum field theory, quantum gravity, unified theories, thermodynamics, statistical mechanics, cosmology, and similar. Acceptance of a paper does not imply endorsement, but is restricted to high quality contributions judged relevant and interesting by the referees and the editors. Short papers can be included in the special category "Letters to the Editor". Authors who wish to raise discussion points or propose articles of a different format are welcome to submit these as well, if they care to explain their wishes with the submission.

物理學的概念基礎從一開始就在不斷地修正，今天仍然如此。基礎問題的討論一直是科學進步的一個主要來源，與經驗知識和數學一樣。例子包括牛頓和后來的愛因斯坦關于空間和時間本質的辯論;論熱與能量的本質論玻爾茲曼引起的不可逆性和概率量子理論早期物質的性質與測量關于重整化的意義，還有很多其他的。今天，對我們在理解物理世界的努力中所使用的概念結構進行深刻的反思具有特別的價值，因為這些嚴重的尚未解決的問題很可能需要再次修改我們對物理世界的科學描述的語法。重力的量子特性,測量在量子力學的本質,不可逆性的主要來源,信息的作用在物理科學——所有這些都是質疑的例子仍困惑和需求的解決方案可能比熟練的數學和新的實驗。物理學基礎是一個特權論壇，討論這些基礎問題，開放給物理學家，宇宙學家，哲學家和數學家。它致力于物理學和宇宙學基本理論的概念基礎，以及它們的邏輯、方法論和哲學前提。該雜志歡迎關于特殊和廣義相對論基礎、量子理論、經典和量子場論、量子引力、統一理論、熱力學、統計力學、宇宙學等問題的論文。接受一篇論文并不意味著認可，但僅限于由審稿人和編輯判斷出相關且有趣的高質量文章。短篇論文可以歸入“給編輯的信”這一特殊類別。希望提出討論點或提出不同格式文章的作者，如果愿意在提交時解釋他們的愿望，也歡迎提交這些討論點或提出不同格式的文章。
