直面物理课堂教学观念

物理课堂教学观念是教师对物理课堂教学功能的总体认识，是教师进行课堂教学组织和实施的指导思想。在新的物理课程标准中明确指出：“物理课程要着眼于学生的发展，使学生获得终生学习的兴趣、习惯及一定的学习能力。教学应力求贴近学生生活，通过学生熟悉的现象揭示物理规律，让学生经历科学探究的过程，学习科学探究的方法，培养科学探究的精神，进而使学生获得对物理知识的理解的同时，在思维能力、情感态度与价值观等多方面得到进步和发展。”因此教师在拟定教育目标，安排教学内容，制定授课过程，选择教学方法，     

新形势下物理教师的素质

当前，以大力提高学生的全面素质为目的。面向全体学生，以培养学生的创新意识，创新精神和创新能力为核心的素质教育的关键是教师．教师素质的高低直接关系到素质教育能否真正实施．笔者作为一名物理教师来谈谈物理教师的素质问题．     

探索性物理实验的双重教育功能

利用现代教育理论，结合物理实验的教学实际，探讨和研究了探索性物理实验的双重教育功能．通过具体的探索性物理实验案例，验证了探索性物理实验具有激发学生的兴趣、发展学生的探索精神和唤起教师创造性的双重教育功能．     

新课程呼唤开放的物理课堂教学

随着素质教育的深入推进、新课程标准的全面实施，广大物理教师必须拥有新的视野，采取新的策略，实现物理课堂教学的全面开放，以便培养出具有创新精神和实践能力的学生．下面通过笔者在近两年来的教学实践，就如何实现物理课堂教学的开放，谈谈自己的认识．     

物理探究教学中应树立六种意识

《普通高中物理课程标准》明确提出：高中物理课程将在义务教育基础上，进一步提高学生的物理科学素养，尤其是发展学生的科学探究能力，帮助学生理解物理科学、技术和社会的相互关系．在教学实践中如何从技术层面上实施课标中的要求，使新课程理念落实到具体的每一节课和每一个教学行为呢？这对广大一线教师来说，是一个迫切需要解决的难题，有必要进行深入地研究．为此，笔者就通过电阻定律这节探究性内容的教学，感到要使探究活动落到实处，真正体现课改精神，教师必须树立六种意识。     

案例教学法分析物理概念的探究

科学探究与案例教学法分析物理概念，能有效的调动学生积极性和主动性；能发挥学生群体的互补性和集体协作精神。这就避免了教师讲解式的教、学生被动式的学的旧教学模式，逐步培养学生的创新意识和创新能力。     

物理解题应与物理情景相结合

物理教师都特别重视对物理概念和规律的教学，通过详细的讲解，帮助学生理解其内容，分析其意义，并要求学生能利用所学理论解决实际问题，真正做到学以致用。而学生在解物理题的过程中，往往认为只要选对公式，并把题目中所给的数据带入公式中即可，甚至认为物理的解题方法与数学的运算过程并无本质区别，只是形式不同而已。殊不知数据在物理解题中有时起着重要的作用。笔者在教学过程中，通过举例，帮助学生理解数据在物理情景中所表示的意义，     

加强物理教学中的素质教育

随着素质教育的逐步推进发展 ,这就要求在物理教学中要将学科理论与当前的科学技术和社会生产及社会生活紧密联系起来 ,不断改革 ,实施素质教育 .下面 ,笔者谈谈在中师物理教学中实施素质教育的具体做法 :1　旁证博引 ,激发学生的爱国主义一个合格的教师 ,必须具有爱国主义精神

Physics Without Physics

David Finkelstein was very fond of the new information-theoretic paradigm of physics advocated by John Archibald Wheeler and Richard Feynman. Only recently, however, the paradigm has concretely shown its full power, with the derivation of quantum theory (Chiribella et al., Phys. Rev. A 84:012311, 2011; D’Ariano et al., 2017) and of free quantum field theory (D’Ariano and Perinotti, Phys. Rev. A 90:062106, 2014; Bisio et al., Phys. Rev. A 88:032301, 2013; Bisio et al., Ann. Phys. 354:244, 2015; Bisio et al., Ann. Phys. 368:177, 2016) from informational principles. The paradigm has opened for the first time the possibility of avoiding physical primitives in the axioms of the physical theory, allowing a re-foundation of the whole physics over logically solid grounds. In addition to such methodological value, the new information-theoretic derivation of quantum field theory is particularly interesting for establishing a theoretical framework for quantum gravity, with the idea of obtaining gravity itself as emergent from the quantum information processing, as also suggested by the role played by information in the holographic principle (Susskind, J. Math. Phys. 36:6377, 1995; Bousso, Rev. Mod. Phys. 74:825, 2002). In this paper I review how free quantum field theory is derived without using mechanical primitives, including space-time, special relativity, Hamiltonians, and quantization rules. The theory is simply provided by the simplest quantum algorithm encompassing a countable set of quantum systems whose network of interactions satisfies the three following simple principles: homogeneity, locality, and isotropy. The inherent discrete nature of the informational derivation leads to an extension of quantum field theory in terms of a quantum cellular automata and quantum walks. A simple heuristic argument sets the scale to the Planck one, and the currently observed regime where discreteness is not visible is the so-called “relativistic regime” of small wavevectors, which holds for all energies ever tested (and even much larger), where the usual free quantum field theory is perfectly recovered. In the present quantum discrete theory Einstein relativity principle can be restated without using space-time in terms of invariance of the eigenvalue equation of the automaton/walk under change of representations. Distortions of the Poincaré group emerge at the Planck scale, whereas special relativity is perfectly recovered in the relativistic regime. Discreteness, on the other hand, has some plus compared to the continuum theory: 1) it contains it as a special regime; 2) it leads to some additional features with GR flavor: the existence of an upper bound for the particle mass (with physical interpretation as the Planck mass), and a global De Sitter invariance; 3) it provides its own physical standards for space, time, and mass within a purely mathematical adimensional context. The paper ends with the future perspectives of this project, and with an Appendix containing biographic notes about my friendship with David Finkelstein, to whom this paper is dedicated.

Physics Needs Philosophy. Philosophy Needs Physics

Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the detection of the Higgs particle and gravitational waves, and the failure to detect supersymmetry where many expected to find it, question the validity of certain philosophical assumptions common among theoretical physicists, inviting us to engage in a clearer philosophical reflection on scientific method.
