3. The Moon’s influence on us

The Moon’s presence in the sky has long pervaded human culture in many ways. ‘The Moon’s influence on us’ considers the influence on timekeeping and how the orbits of the Moon and Earth are the origin of our calendar. Ocean tides are caused by the gravitational pull of the Moon and Sun on ocean water with the Moon’s influence being twice as strong as the solar tide. The elliptical nature of the Moon’s orbit affects lunar and solar eclipses; these are explained along with orbital recession and day-length changes. The Moon’s influence on human behaviour and wildlife is also considered, along with the potential of a more sustained lunar presence in the future.

Both the concepts of plate tectonics and continental drift conceive that the planet earth’s dimension, associated with its oceans, has remained unchanged throughout the past geological periods. In contrast, Hilgenberg’s model of earth expansion endorses that initially the planet was considerably small and devoid of oceans [1]. Based on earth expansion theory the author has pointed out that since the primordial condensed or small earth was devoid of oceans, initially the ocean-forming water must have been associated with the mantle, thereby turning that geosphere considerably fluid and pre-eminently suitable for planetary expansion. Expansion of the planet appears to have been caused owing to swelling up of the semi-fluid mantle in response to an external gravitational pull caused by an extra-terrestrial planetary body, probably the Moon. The primordial earth was completely covered with a relatively thin granitic crust, which, due to swelling up of the mantle developed a number of long and sinuous expansion cracks. Through these expansion cracks widespread eruption of molten magma took place spreading on both sides of the cracks to form rudimentary oceans basins. With continued expansion, the dimension of the oceans was broadened while the expansion cracks turned in to mid-oceanic ridges. Associated with expulsion of molten lava, large quantum of volatiles, chiefly constituted of water was released from the mantle that formed the ocean water while due to desiccation of the mantle, the process of expansion was eventually stopped.

Many animals that breed seasonally measure the day length (photoperiod) and use these measurements as predictive information to prepare themselves for annual breeding. For several decades, thyroid hormones have been known to be involved in this biological process; however, their precise roles remain unknown. Recent molecular analyses have revealed that local thyroid hormone activation in the hypothalamus plays a critical role in the regulation of the neuroendocrine axis involved in seasonal reproduction in both birds and mammals. Furthermore, functional genomics analyses have revealed a novel function of the hormone thyrotropin. This hormone plays a key role in signaling day-length changes to the brain and thus triggers seasonal breeding. This review aims to summarize the currently available knowledge on the interactions between elements of the thyroid hormone axis and the neuroendocrine system involved in seasonal reproduction.

Is war beginning to escape human control? Thucydides tells us the war is one of the things that makes us definitively human; but how long will this continue to be the case as our relationship with technology continues to develop? Kenneth Waltz’s book Man, the State and War affords one way of answering that question. So too does Nikolaas Tinbergen’s framework for understanding human behaviour and Bruno Latour’s Actor–Network Theory (ANT). The main focus of this article is the extent to which we will diminish or enhance our own agency as human beings, especially when we come to share the planet with an intelligence higher than our own.

Chapter 4 opens with a discussion of the mass graves of unidentified immigrants discovered in South Texas in 2014. How, confronted with these decayed, dismembered border bodies, can literature and art move us beyond horror into a more just tomorrow? To answer, the author turns to two Chicanx science fiction novels: Morales’s The Rag Doll Plagues (1992) and Pita and Sánchez’s Lunar Braceros (2009). Morales’s novel begins in colonial Mexico with a tale of La Mona, an unidentified plague similar to AIDS, and ends in a Los Angeles of the future, now known as LAMEX, beset by a similar disease curable only by the infusion of blood from “pure” Mexicans and threatened by waves of trash, which have taken on the characteristics of an animated organism, rolling in from the Pacific. Lunar Braceros, about nuclear waste workers of the future living on the moon, presents trash as a similarly transformative threat. Both novels offer conflicted visions of the human body as simultaneously of and apart from the land, a vulnerable but powerful catalyzing agent for change. The author frames this chapter with analyses of works in Mexican Canadian digital installation artist Rafael Lozano-Hemmer’s Relational Architecture series.

The human exploration of planetary bodies started with the Apollo missions to the Moon, which provided valuable lessons learned and experience for the future human exploration. Based on that, the design of hardware and operations need to further be developed to also overcome the new challenges, which arise when planning crewed missions to Mars and beyond. This chapter provides an overview about the environment and structure of the Red Planet and discusses the challenges on operations and hardware correlated to it. It further provides insights into the considerations regarding the hardware development which need to be investigated and defined before launching a crewed mission to Mars.

They say if you drop a live frog into a pot of boiling water, it will jump right out. But, if you place the same frog into a pot of water at room temperature and then gradually raise the flame under it, the frog will not notice the changes and remain in the pot until it is cooked. Now, you might ask, what is the connection between a frog in a pot and what a millennium teacher should know and be able to do? My view of the connection is that there are events and processes happening around us every day. Most of the time, we do not pay them much attention because they occur so frequently or gradually that from moment to moment they do not seem to signify very much—like the gradually rising temperature in the pot of the cooking frog. Once in a great while, a potentially transformative event occurs and it makes us jump: September 11, Columbine, sending a man to the moon, or Y2K hysteria. Usually though, we conduct our routines and make our way through the day or the semester and tend to rely on the comfort of the familiar, seemingly unchanging, landscape. Yet, were we to carefully study and reflect upon that landscape, we might discern important trends that hold meaning for how we conduct ourselves presently, and in the future.

AbstractSports, one of the symbols of the global human culture and a unit of peaceful society, excite both competitors and audiences. During the game and even practice, athletes concentrate to choose not only a comfortable design but also high-performing materials of their shoes, rackets, uniforms, etc. Under the high demand of athletes, sports materials are evolving with the support of new chemical reactions and coordination chemistry. Here, we exhibit the role of elements in sports. The International Year of the Periodic Table (IYPT) will bring chemistry into the future as The Olympic & Paralympic Games in Tokyo in 2020.
