To displace a character in time is to depict a character who becomes acutely conscious of his or her status as other, as she or he strives to comprehend and interact with a culture whose mentality is both familiar and different in obvious and subtle ways. Two main types of time travel pose a philosophical distinction between visiting the past with knowledge of the future and trying to inhabit the future with past cultural knowledge, but in either case the unpredictable impact a time traveller may have on another society is always a prominent theme. At the core of Japanese time travel narratives is a contrast between self-interested and eudaimonic life styles as these are reflected by the time traveller's activities. Eudaimonia is a ‘flourishing life’, a life focused on what is valuable for human beings and the grounding of that value in altruistic concern for others. In a study of multimodal narratives belonging to two sets – adaptations of Tsutsui Yasutaka's young adult novella The Girl Who Leapt Through Time and Yamazaki Mari's manga series Thermae Romae – this article examines how time travel narratives in anime and live action film affirm that eudaimonic living is always a core value to be nurtured.

Mental time travel (MTT) is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: (1) acts on the same information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; (2) is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two (cf. predictive coding); and (3) is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this simulation system, enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

This chapter is about the arrow or direction of time against the backdrop of the pure manifold theory. It is accepted that the fact that time has a direction ought to be explained. It is proposed that the arrow of time is grounded in deeper facts about the four-dimensional nature of each object in the manifold and in facts about the overall four-dimensional shape of the universe. Towards the end of the chapter the possibility of time travel is discussed. It is argued that time travel is metaphysically possible and that there is a reasonable and intelligible sense in which a time traveler can and cannot change the past, according to the pure manifold theory.

Bosnia and Herzegovina (BH) has a very picturesque past. Founded in 11th century, it has always been a crossroads of faiths and civilizations. Extended Reality (XR) technologies can finally take us to time travel into this history, enable us to experience past events and meet historical characters. In this paper, we overview the latest applications we developed that use Virtual Reality (VR) video, Virtual and Augmented Reality (AR) for interactive digital storytelling about BH history. “Nine dissidents” is the first BH VR documentary, tackling a still tricky subject of dissidents in the Socialist Yugoslavia, artists and writers falsely accused, persecuted and still forbidden. “Virtual Museum of Old Crafts” aims to present and preserve crafts intangible heritage through Virtual Reality. “Battle on Neretva VR” is recreating a famous WWII battle offering the users to experience it and meet comrade Tito, the commander of the Yugoslav Liberation Army. “Sarajevo 5D” shows the cultural monuments from Sarajevo that do not exist anymore in physical form using Augmented Reality. Through user experience studies, we measure the user immersion and edutainment of these applications and show the potential of XR for the presentation and preservation of cultural heritage.

A little discussed aspect of Heaviside's work in electromagnetics concerned faster-than-light (FTL) charged particles, precursors to the hypothetical tachyon and his discovery that such motion should produce a characteristic radiation signature (now called Cherenkov radiation ). When Heaviside wrote, the time travel implications of FTL were not known (Einstein was still a teenager), and in this paper some speculations are offered on what Heaviside would have thought of FTL time travel, and of the associated (now classic) time travel paradoxes, including the possibility (or not) of sending information into the past. This article is part of the theme issue ‘Celebrating 125 years of Oliver Heaviside's ‘Electromagnetic Theory’’.

This article presents an overview of case studies of acquired disorders of musical listening. Like any cognitive faculty, music is multifaceted, and the identification of the neural basis of any complex faculty must proceed, hand in hand, with an elucidation of its cognitive architecture. The past decade has seen an evolution in the theoretical models of musical processing, allowing the development of theoretically motivated instruments for the systematic evaluation of musical disorders. Such developments have allowed reports of musical disorders to evolve from historical anecdotes to systematic, verifiable accounts that can play a critical role in contributing to our understanding of the cognitive neuroscience of music.

The main topic of this article are the motives that led to the adoption of lustration laws in the Czech Republic, Poland, and Serbia, and their social functions. In the opening section, lustration is placed in the wider framework of dealing with the past and two possible approaches to the phenomenon are discussed: to take it as part of the broader process of decommunization, or a measure of transitional justice. In the next section an attempt at defining the concept of lustration is made, with a view to eliminating some ambiguities surrounding it. Subsequently, two partially complementary theoretical models explaining the occurrence, form and severity of dealing with the past and lustration are presented. After that comes the description of the socio-political context at the time of the adoption of lustration laws in the three countries and identification of political and ideological forces that have supported or challenged it. Finally, the article attempts to answer the question whether lustration is a legitimate measure of settling historical justice, overcoming the legacies of socialism, a way to strengthen liberal democracy, or merely a tool in political struggles for power.

<p>Public history and academic history have been viewed both as opposites, two practices related only by their concern with sharing the past, as well as conceptualised as similar fields with close connections to each other. Museum history exhibitions are an obvious example of public history in action. However, is the history that exhibitions present all that different from what is produced in the academy, or is this history academia in another form? Initially this dissertation aimed to explore the relationships between academic and public histories as discipline and practice, assuming a relationship rather than divide between the two fields as suggested in some of the literature. However, the eventual results of the research were different than expected, and suggested that in fact public histories manifest very differently to academic histories within a museum context. Using an adapted ethnographic research methodology, this dissertation traces the development of a single history exhibition, "Te Ahi Kā Roa, Te Ahi Kātoro Taranaki War 1860–2010: Our Legacy – Our Challenge", from its concept development to opening day and onwards to public programmes. This exhibition opened at Puke Ariki in New Plymouth in March 2010, and was a provocative display not only of the history of the wars themselves, but of the legacy of warfare in the Taranaki community. Other methods include partially structured interviews which were conducted with ten people involved in creating this exhibition, who outlined their roles in its production and provided their views on its development, and also a brief analysis of the broader social and historical context in which the exhibition was staged. Through tracing the creation of this history, the findings suggested that the history produced at Puke Ariki is a history in its own right, with noticeable differences from academic histories. The strongest correlation between public and academic history in this instance was the shared aspiration to be rigorous in conducting research and, as far as possible, to create an accurate portrayal of the past. Otherwise the history created by Puke Ariki through the exhibition proved to be different in that it was deliberately designed to be very accessible, and it utilised a number of presentation modes, including objects, text, audiovisual and sound. It was interactive, and had a clear aim of enabling the audience to participate in a discussion about the history being presented. Finally, it was a highly politicised history, in that decision making had to be negotiated with source communities in a collaborative fashion, and issues of censorship worked through with the council, a major funding source. The dissertation concludes that producing history in a museum context is a dynamic and flexible process, and one that can be successful despite not necessarily following theoretical models of exhibition development.</p>

AbstractI argue that time travel to the past is impossible, given a certain metaphysical theory, namely, The Dynamic Theory of Time. I first spell out my particular way of capturing the difference between The Dynamic Theory of Time and its rival, The Static Theory of Time. Next I offer four different arguments for the conclusion that The Dynamic Theory is inconsistent with the possibility of time travel to the past. Then I argue that, even if I am wrong about this, it will still be true that The Dynamic Theory entails that you should not want to travel back to the past. Finally, I conclude by considering a puzzle that arises for those who believe that time travel to the past is metaphysically impossible: What exactly are we thinking about when we seem to be thinking about traveling back in time? For it certainly does not feel like we are thinking about something that is metaphysically impossible.
