The Seven Principles for Making Marriage Work
The Seven Principles for Making Marriage Work, by John Gottman is a book that sets forth what it describes as seven principles that can guide toward a harmonious and long-lasting relationship. The book attempts to debunk a number of what it describes as myths about marriages and why they fail. The seven principles Gottman sets out are for the partners to enhance their love maps; nurture fondness and admiration; turn toward each other instead of away; let their partner influence them; solve their solvable problems; overcome gridlock; and create shared meaning. The book was included in the Comprehensive Soldier fitness program. A follow-up to this book was the 2013 What Makes Love Last?

Proto-Romanian Language
Proto-Romanian (also known as "Common Romanian", româna comună or "Ancient Romanian", străromâna, Balkan Latin) is a hypothetical and unattested Romance language evolved from Vulgar Latin and considered to have been spoken by the ancestors of today's Romanians and related Balkan Latin peoples (Vlachs) before c. 900 (7th–11th century AD). In the 9th century Proto-Romanian already had a structure very distinct from the other Romance languages, with major differences in grammar, morphology and phonology and already was a member of the Balkan language area. Most of its features can be found in the modern Balkan Romance languages. It already contained around a hundred loans from Slavic languages, including words such as trup (body, flesh), as well as some Greek language loans via Vulgar Latin, but no Hungarian and Turkish words as these nations had yet to arrive in the region. According to the Romanian theory, it evolved into the following modern languages and their dialects: The first language that broke the unity was Aromanian, in the 9th century, followed shortly after by Megleno-Romanian. Istro-Romanian was the last to break the link with Daco-Romanian in the 11th century. The place where Proto-Romanian formed is still under debate; most historians put it just to the north of the Jireček Line. See: Origin of Romanians. The Roman occupation led to a Roman-Thracian syncretism, and similar to the case of other conquered civilisation (see Gallo-Roman culture developed in Roman Gaul), had as final result the Latinization of many Thracian tribes which were on the edge of the sphere of Latin influence, eventually resulting in the possible extinction of the Daco-Thracian language (unless, of course, Albanian is its descendant), but traces of it are still preserved in the Eastern Romance substratum. From the 2nd century AD, the Latin spoken in the Danubian provinces starts to display its own distinctive features, separate from the rest of the Romance languages, including those of western Balkans (Dalmatian). The Thraco-Roman period of the Romanian language is usually delimited between the 2nd century (or earlier via cultural influence and economic ties) and the 6th or the 7th century. It is divided, in turn, into two periods, with the division falling roughly in the 3rd to 4th century. The Romanian Academy considers the 5th century as the latest time that the differences between Balkan Latin and western Latin could have appeared, and that between the 5th and 8th centuries, the new language, Romanian, switched from Latin speech, to a vernacular Romance idiom, called Română comună.

Neuroarchaeology
Neuroarchaeology refers to a field of study that records neuroscientific history through archaeological methods of investigation. The term was first suggested and thus coined by Colin Renfrew and Lambros Malafouris first individually in 2004 and then collaboratively in 2008.It is a combination of the words "neuro-" from 'neuroscience' indicating its connection with the brain sciences and "archaeology" meaning study of human history and prehistory through excavations and other tools. Significant leaps in brain and cognitive sciences in the 21st century have opened up new areas of partnership between archaeology and neuroscience. This collaboration can help an archaeologist figure out biological and neural substrates of human cognitive abilities present in the archaeological objects. The knowledge of neuroscience can also be applied to critically review and challenge existing theories and assumptions about the inception of modern human cognition. The term implies a new area of research that could investigate issues relating to the collaboration between the brain and culture over the long term development of humans. So far, the goals of neuroscience and archaeology are the same- to understand human nature. But their disciplinary approaches diverge significantly. Neuroarchaeology aims at building the analytical bridge between brain and culture ""by putting material culture, embodiment, time and long-term change at centre stage in mind".

List of Largest Stars
Below is a list of the largest stars currently known, ordered by radius. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). The angular diameters of stars can be measured directly using stellar interferometry. Other methods can use lunar occultations or from eclipsing binaries, which can be used to test indirect methods of finding stellar radii. Only a few useful supergiant stars can be occulted by the Moon, including Antares A (Alpha Scorpii A). Examples of eclipsing binaries are Epsilon Aurigae (Almaaz), VV Cephei, and V766 Centauri (HR 5171). Angular diameter measurements can be inconsistent because the boundary of the very tenuous atmosphere (opacity) differs depending on the wavelength of light in which the star is observed. Uncertainties remain with the membership and order of the list, especially when deriving various parameters used in calculations, such as stellar luminosity and effective temperature. Often stellar radii can only be expressed as an average or be within a large range of values. Values for stellar radii vary significantly in different sources and for different observation methods. All the sizes stated in this list have various inaccuracies and may be disputed. This list is still a work in progress and various parameters are extremely disputed.

Luxury Yacht
A Luxury yacht (also super-yacht, large yacht and mega-yacht) is a very expensive, privately owned, professionally crewed sailing or motor yacht. There is no industry-wide standard for the difference between super-yacht and mega-yacht. The only legal distinction is between yachts above 24 metres (79 ft) and below, as in some countries those above 24 meters must have a permanent crew onboard. This term began to appear at the beginning of the 20th century, when wealthy individuals constructed large private yachts for personal pleasure, such as Charles Henry Fletcher's Jemima F. III, at 111 feet, the largest motor-powered yacht in the world in 1908. More examples of early luxury motor yachts include the Cox & King yachts, Charles L. Seabury and Company's yachts, M/Y (motor yacht) Christina O, and M/Y Savarona.

Dhammakaya Meditation
Dhammakaya meditation is a method of Buddhist meditation developed and taught by the Thai meditation teacher Luang Pu Sodh Candasaro (1885–1959).[note 1] In Thailand, it is known as vijjā dhammakāya, which translates as 'knowledge of the body of truth'. It is the meditation tradition that is at the center of the Dhammakaya Movement. The Dhammakaya meditation method has become very popular in Thailand and other parts of Southeast Asia, and has been described as a revival of samatha (tranquility) meditation in Thailand. The method was discovered by Luang Pu Sodh in the 1910s. Followers of the Dhammakaya Movement believe the method was the same as the original method the Buddha used to attain enlightenment. According to Luang Pu Sodh, the Dhammakāya, the core concept of the tradition, can be found within every human being. The most important aspect of the meditation method is the focus on the center of the body. As of 2008, there was still scholarly debate as to the origins of Dhammakaya meditation. Scholars refer to the Yogavacara tradition as a possible source, or that the method might be new or partly new. Dhammakaya meditation is taught at several temples of the movement, and consists of a stage of samatha (tranquility) and vipassana (insight), following the structure of the Visuddhimagga, a standard fifth-century Theravāda guide about meditation. In the method, the stages are described in terms of inner bodies (Pali: kāya), but also in terms of meditative absorptions (Pali: jhānas). Dhammakaya meditation has been the subject of considerable discussion among Buddhists as to its authenticity and efficacy, and also has been the subject of several scientific studies.
