“…Since the first direct observation of gravitational waves (GWs), carried out by the interferometers of the LIGO/VIRGO collaboration [1], gravitational radiation has proved to be a precious messenger of information for astrophysics, allowing not only to confirm the predictions of general relativity [2,3] but also to study extraordinary phenomena, such as the merger of neutron stars [4], and to discover several black holes [5]. However, gravitational astronomy is still in its infancy and to date, only the tip of the iceberg of the GW spectrum has been scratched.…”

The standard technique for very low-frequency gravitational wave detection is mainly based on searching for a specific spatial correlation in the variation of the times of arrival of the radio pulses emitted by millisecond pulsars with respect to a timing model. This spatial correlation, which in the case of the gravitational wave background must have the form described by the Hellings and Downs function, has not yet been observed. Therefore, despite the numerous hints of a common red noise in the timing residuals of many millisecond pulsars compatible with that expected for the gravitational wave background, its detection has not yet been achieved. By now, the reason is not completely clear and, from some recent works, the urgency to adopt new detection techniques, possibly complementary to the standard one, is emerging clearly. Of course, this demand also applies to the detection of continuous gravitational waves emitted by supermassive black hole binaries populating the Universe. In the latter case, important information could, in principle, emerge from the millisecond pulsars considered individually in a single-pulsar search of continuous GWs. In this context, the surfing effect can then be exploited, helping to select the best pulsars to carry out such analysis. This paper aims to clarify when the surfing effect occurs and describe it exhaustively. A possible application to the case of the supermassive black hole binary candidate PKS 2131–021 and millisecond pulsar J2145–0750 is also analyzed.

“Science” and “art” as ways of knowing in school education in Nepal for an inclusive learning environment

et al. 2023

View full text Add to dashboard Cite

For several years, science and art have been viewed as separate entities in school education in Nepal. The dominant discourse on science was regulated by Western Modern Worldview (WMW), assuming that seeking universal truth should be the central aim of the exploration. In this article, science refers to the absolutist/rigid nature of different disciplines (such as Science and Mathematics) from the perspectives of Newtonian science, whereas art is viewed from three dimensions; literary arts (i. e. narratives, storing), visual arts (i.e., images, painting, sculpture) and performing arts (i.e., role play, drama). This paper argues that science and arts, as ways of knowing, should be taken as complements of each other. This literature-based argumentative paper also incorporates the lead author’s experiences using art as/for pedagogical approaches in collaboration with schoolteachers. At the same time, the authors also argue the role of critical reflection to acknowledge both science and art as epistemology. The authors have used Dewey's perspectives on the roles of art for experiencing in education. Also, the notion of Mezirow’s Transformative Learning is helpful as an influential lens to showcase the ever-changing thoughts in the transformation continuum. To set the context for the argumentation, the authors discussed the existing Nepali school education system, focused on curricula and pedagogical perspectives. The paper is helpful for teachers, teacher educators, and researchers to critically reflect on their own beliefs and practices in terms of viewing the different perspectives on STEM subjects and the inseparable relationship of science and art for knowledge generation and pedagogical application.
