With quantum teleportation likely to play a key role in several\u0000communication technologies and the quantum internet in the future, it is\u0000imperative to create learning tools and approaches that can accurately and\u0000effectively communicate the concept. Recent research has indicated the\u0000importance of teachers enthusing students about the topic of quantum physics.\u0000Therefore, educators at both high school and early university level need to\u0000find engaging and perhaps unorthodox ways of teaching complex, yet interesting\u0000topics such as quantum teleportation. In this paper, we present a paradigm to\u0000teach about the concept of quantum teleportation using the Christmas\u0000gift-bringer Santa Claus. Using the example of Santa Claus, we use an unusual\u0000context to explore the key aspects of quantum teleportation, and all without\u0000being overly abstract. In addition, we outline a worksheet designed for use in\u0000the classroom setting which is based on common misconceptions from quantum\u0000physics.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"28 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522948","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 paper\u0000reviews both the hardware and software techniques which this collaboration\u0000employed, and contains a frank discussion of the successes and failures, with a\u0000section about how to apply lessons learned to future expeditions. Both\u0000observable-light and infrared cameras were deployed, as well as sensors for\u0000other (non-EM) emissions. A pixel-subtraction method was augmented with other\u0000similarly simple methods to provide initial identification of objects in the\u0000sky and/or the sea crossing the cameras' fields of view. The first results will\u0000be presented based upon approximately one hour in total of triggered\u0000visible/night-vision-mode video and over 600 hours of untriggered (far) IR\u0000video recorded, as well as 55 hours of (background) radiation measurements.\u0000Following multiple explanatory resolutions of several ambiguities that were\u0000potentially anomalous at first, we focus on the primary remaining ambiguity\u0000captured at approximately 4am Pacific Time on Friday, July 16: a dark spot in\u0000the visible/near-IR camera possibly coincident with ionizing radiation that has\u0000thus far resisted a prosaic explanation. We conclude with quantitative\u0000suggestions for serious researchers in this still-nascent field of\u0000hard-science-based UAP studies, with an ultimate goal of identifying UAPs\u0000without confirmation bias toward either mundane or speculative conclusions.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"177 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522949","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}

There is a negligible chance that Earth's orbit will\u0000change during that time through internal Solar System dynamics. However, there\u0000is a ~1% chance per Gyr that a star will pass within 100 au of the Sun. Here,\u0000we use N-body simulations to evaluate the possible evolutionary pathways of the\u0000planets under the perturbation from a close stellar passage. We find a ~92%\u0000chance that all eight planets will survive on orbits similar to their current\u0000ones if a star passes within 100 au of the Sun. Yet a passing star may disrupt\u0000the Solar System, by directly perturbing the planets' orbits or by triggering a\u0000dynamical instability. Mercury is the most fragile, with a destruction rate\u0000(usually via collision with the Sun) higher than that of the four giant planets\u0000combined. The most probable destructive pathways for Earth are to undergo a\u0000giant impact (with the Moon or Venus) or to collide with the Sun. Each planet\u0000may find itself on a very different orbit than its present-day one, in some\u0000cases with high eccentricities or inclinations. There is a small chance that\u0000Earth could end up on a more distant (colder) orbit, through re-shuffling of\u0000the system's orbital architecture, ejection into interstellar space (or into\u0000the Oort cloud), or capture by the passing star. We quantify plausible outcomes\u0000for the post-flyby Solar System.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"154 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138523053","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}

It is\u0000part of many undergraduate curriculums and it is often suggested that it should\u0000be integrated into an upper secondary curriculum. Special Theory of Relativity\u0000combines time and space whereas General Theory of Relativity describes gravity\u0000as a geometric property of spacetime. As it describes abstract phenomena,\u0000students encounter several difficulties understanding its basic principles and\u0000consequences. In this paper, we present the research that we conducted in order\u0000to detect the aforementioned difficulties. This research constitutes a part of\u0000a more general study concerning the integration of Special and General\u0000Relativity into an upper secondary and undergraduate curriculum. The sample\u0000consisted of 45 non-major physics undergraduate students. The purpose of our\u0000study was to determine and categorize the difficulties students face when they\u0000study the principles of the Theory of Relativity and its consequences. The\u0000results of our research indicate that student face many obstacles when trying\u0000to interpret phenomena described by the Relativity and confuse Special and\u0000General Relativity principles. These results dictate us to create an\u0000educational approach that tackle the difficulties found.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"58 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522950","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}
