The 4th Physics Conference of Portuguese Speaking Countries (4a Conferência de Física dos Países de Língua Portuguesa - CFPLP) was held in Cidade da Praia, Cabo Verde, from 14 through 16 September 2022. The Conference was hosted by the Universidade de Cabo Verde (UniCV) and took place on its new beautiful campus.

The 4th CFPLP was organized by the Union of Physicists from Portuguese Speaking Countries (União de Físicos dos Países de Língua Portuguesa - UFPLP) and UniCV with institutional support from the CPLP (Comunidade de Países de Língua Portuguesa) with financial and infrastructure support from the Portuguese and Brazilian Physical Societies, EPS and IUPAP, among others. Professor Sónia Semedo from UniCV chaired the Organizing Committee. The main theme of the Conference was “Physics for sustainable development” in the framework of the “International Year of Basic Sciences for Sustainable Development”.

Professor Ricardo Galvão from Brazil chaired the Scientific Advisory Committee, and the program highlighted the following topics: Dissemination and teaching of Physics (including digital teaching and applications); Environment and  climate change; Ocean pollution and disaster prevention; Sustainable energy sources; Contributions from Physics to engineering; Physics for life; Space technology, in particular, the use of nanosatellites; Complex systems; Artificial intelligence; Nanotechnologies.

The 4th CFPLP was a hybrid event with around 81 participants from Angola, Brasil, Cabo Verde, Moçambique, Portugal, São Tomé and Principe, and the USA , with 30% participating remotely via Zoom. Among them there were 23 students and 25 high-school teachers. Professor Teresa Pena from Portugal gave a welcome talk in the opening ceremony on behalf of the EPS.

Previous to the Conference, there were two days of training activities for 25 Cabo-Verdean high school teachers. The workshops were: Introduction to Python with Physics applications and Elab- remote physics labs; Optics and “Show da Física”; Applications of nuclear energy in health, industry, environment, agriculture, and cultural goods; and Masterclasses in Particle Physics.

This series of Conferences are highly valuable for the dissemination of Physics in Portuguese Speaking Countries that can lead to the development of this and related fields in these countries.
