The book "Modern Mathematics: An International Movement?" edited by Dirk De Bock explores the complexities of the modern mathematics movement, also known as the New Math, which aimed to reform mathematics education on a global scale. The text delves into the unique national characteristics that influenced the implementation and outcomes of this movement, challenging the notion of a singular, international agenda. Through detailed case studies from various countries, the book highlights the diverse perspectives and influences that shaped the modern mathematics movement, ultimately leading to reflections on the nature of mathematics education.

The article discusses the book "Mathematical Tools for Real-World Applications: A Gentle Introduction for Students and Practitioners" by Alexandr Draganov, which explores the application of mathematical techniques to real-world and pure mathematical problems. The author highlights examples from the book that demonstrate how STEM-inspired thinking can be applied to pure mathematical problems, expanding the reach of mathematics beyond just engineering and technology. The article concludes by stating that Draganov's book provides valuable reflections on the role of STEM in mathematics education. [Extracted from the article]

Interest in Criegee intermediates (CIs), often termed carbonyl oxides, and their role in tropospheric chemistry has grown massively since the demonstration of laboratory‐based routes to their formation and characterization in the gas phase. This article reviews current knowledge regarding the electronic spectroscopy of atmospherically relevant CIs like CH2OO, CH3CHOO, (CH3)2COO and larger CIs like methyl vinyl ketone oxide and methacrolein oxide that are formed in the ozonolysis of isoprene, and of selected conjugated carbene‐derived CIs of interest in the synthetic chemistry community. Of the aforementioned atmospherically relevant CIs, all except CH2OO and (CH3)2COO exist in different conformers which, under tropospheric conditions, can display strikingly different thermal loss rates via unimolecular and bimolecular processes. Calculated photolysis rates based on their absorption properties suggest that solar photolysis will rarely be a significant contributor to the total loss rate for any CI under tropospheric conditions. Nonetheless, there is ever‐growing interest in the absorption cross sections and primary photochemistry of CIs following excitation to the strongly absorbing 1ππ* state, and how this varies with CI, with conformer and with excitation wavelength. The later part of this review surveys the photochemical data reported to date, including a range of studies that demonstrate prompt photo‐induced fission of the terminal O–O bond, and speculates about possible alternate decay processes that could occur following non‐adiabatic coupling to, and dissociation from, highly internally excited levels of the electronic ground state of a CI.
