{"title":"From Earth to Space and Back Again: A Story of Geophysics Told by 130 Years of AGU Article Titles","authors":"Paige Wooden","doi":"10.1029/2024cn000241","DOIUrl":"https://doi.org/10.1029/2024cn000241","url":null,"abstract":"We present an analysis of the most frequent words in journal article titles published by the American Geophysical Union (AGU), including articles of its first acquired journal Terrestrial Magnetism (and Atmospheric Physics) from the journal's inception in 1896, before AGU acquired it as Journal of Geophysical Research in 1959. The analysis tells one story of the development of the field of geophysics between 1896 and 2023. This story begins with studying the Earth's magnetic field and the sun's effects on it. Published article content expanded to include Earth's immediate atmosphere and as technology allowed, atmospheric composition further and further from Earth. Around the mid‐twentieth century, geophysics expanded to more rigorously study Earth's aqueous environments, and title words show that geophysicists understood that these environments could tell the story of Earth's past while predicting Earth's future. We group the analysis into multi‐decadal years for the following journals: Terrestrial Magnetism (updated to Terrestrial Magnetism and Atmospheric Electricity in 1899 and Journal of Geophysical Research in 1949), (Eos) Transactions (from 1920 to 1959), Reviews of Geophysics, Water Resources Research, Radio Science, Geophysical Research Letters (GRL), Tectonics, Paleoceanography, Global Biogeochemical Cycles (GBC), Geochemistry, Geophysics, Geosystems (G‐Cubed), Space Weather, Journal of Advances in Modeling Earth Systems (JAMES), JGR: Space Physics, JGR: Solid Earth, JGR: Oceans, JGR: Atmospheres, JGR: Planets, JGR: Earth Surface, JGR: Biogeosciences, Earth's Future, Earth and Space Science, GeoHealth, AGU Advances, Perspectives of Earth and Space Scientists, and Community Science.","PeriodicalId":471609,"journal":{"name":"Perspectives of earth and space scientists","volume":"112 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Last year we had 56 reviews and this year it was 49. As a relatively young journal, Perspectives is still defining its role withing AGU. This year Perspectives added several new article formats in order to help support intra‐AGU communication. These new formats included Commentaries, Opinions, News Items, and Memorials, which means additional challenges for reviewers, as the review criteria for these new formats vary from each other. This year also saw an increase in the diversity of styles and authorships of Perspectives Articles, which are the primary format of the journal, but the bulk of these Articles still took a large‐scale big‐picture view of a particular scientific perspective, across the full range of Earth and space sciences. Once again this year, we are very grateful for the wisdom and flexibility shown by our reviewers, and the entire editorial board of Perspectives would like to express our deep appreciation for all the work they have done.

This perspective paper delves into the experiences and outcomes of a summer school held in person in Boulder, Colorado, USA, from 7–11 August, which offered a platform for interdisciplinary learning and collaboration. The event, supported by NASA's Living with a Star program and hosted by the University Corporation for Atmospheric Research and Cooperative Programs for the Advancement of Earth System Science, assembled a cohort of 26 graduate students and postdoctoral researchers from around the world, all engaged in heliophysics research. The summer school included a series of lectures, interactive activities, and a culminating capstone project. The participants' diverse backgrounds enriched discussions and encouraged novel approaches to traditional problems. The capstone projects spanned an array of topics, including investigating the origins of solar wind switchbacks, dissecting the sequence of events from solar eruptions and their corresponding terrestrial consequences, investigating the energy transfer from solar coronal mass ejections to Earth's magnetosphere, and advocating for the exploration of Coulomb collisions in understanding large‐scale global systems. Through this perspective, we shed light on the value of international and interdisciplinary collaboration in advancing heliophysics research. This perspective paper encapsulates the ethos of the summer school, serving as a testament to the continuing and collective pursuit of unraveling the mysteries of the heliosphere.","PeriodicalId":471609,"journal":{"name":"Perspectives of earth and space scientists","volume":"124 S174","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140428919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I then move to our formal mathematical system and show that even in this formal system we cannot do away with randomness and that the randomness in the physical world is consistent with the origins of randomness suggested from the study of mathematical systems. Rules and randomness are blended together and their interaction is shaping all observed forms and structures.","PeriodicalId":471609,"journal":{"name":"Perspectives of earth and space scientists","volume":"25 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139608264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This broadens the scientific impact of “tectonics” and makes it useful to outline a few guiding principles. For many, the term “tectonics” is synonymous with Plate Tectonics on Earth, but it should not be limited to only the planet we know best. Specifically, the concept should be generalized to encompass other rocky planets and moons in our Solar System and exoplanets.
