What if the moon disappeared when no one was looking at it? What if time worked differently for each of us? What if things you could touch were made out of ideas? What if a decision you made now changed history 10 billion years ago? What if experiments showed that another dimension exists? Quantum physics and relativity, two of the most important advances in modern science, are normally presented as a series of technical discoveries in 20th century Europe. Yet this (...) brief, easy-to-read volume shows how they were underpinned by centuries of observations about the nature of reality from the great philosophies and faiths of humanity, from China to India to the Middle East. At each stage, the people involved found themselves saying: "That's impossible! That makes no sense. And yet... (shrink)

We understand from the oldest sources that have reached us that according to their status, racial characteristics, culture, religion etc. people called their adressees with many different names besides their own names. The Arabic nicknames and titles, which are the main subject of our research result of this necessity. Before the formation of Islamic culture and civilization, different titles were used in all civilizations, especially in the Byzantine and Sassanid empires, for the members of the group, which were considered as (...) the elite class, apart from their names. Of course, the Arab society of jahiliyyah was also greatly influenced by his. In the political and bureaucratic structure created by the rapid spread of Islam and the interaction from different civilizations, a new naming, or rather nicknames, were made by using religious figures. This happened to such extend that the original names of many rulers remained in the shadows. The strict centralist structure of the Umayyad state required an authoritarian state administration that would not need excessive credit or definition. Therefore, the caliph did not need an extra nickname or title to define himself. At the same time, it would be appropriate to say that they never had any thoughts of praising the politicians and bureaucrats affiliated with them. The radical change in the political understanding with the Abbasid revolution also led to a great change in naming strategies. In fact, it is possible to explain the differentiation in this management approach through titles in the shortest way. The famous names of the Abbasid caliphs are nothing but nicknames. These names, which are adorned with the words of Allah, are actually an effort to show religious sensitivity to the subjects. The sensitivity in the language of diplomacy has come to the fore even more with the special divans established. The language of religion and the language of politics have been intertwined, and the caliph, who is the representative of the creator on earth, has been giving nicknames/titles around him. We see the actual situation of this practice as concrete in relation to the vassal states. During the Abbasid period, the level of relations between the states, which first emerged as semi-independent and later independent, and the caliphate differed according to time and conditions. In proportion to the political power of the Abbasid state, these heads of state were given different ranks. In this research, we try to reveal the background of the ranks given to the heads of vassal state established in the Khorasan and Transoxiana region and carrying out very important activities in the political sense. Additionally, we aim reveal to find out the political, religious and social structure of Tahirids, Saffarids, and Samanids, who are also very important in terms of Turkish history and serve as a bridge between the region and the center of the caliphate, Baghdad. We think that the subject discussed is important in order to discover the unknown aspects of the historical process in the political and bureaucratic formation of the Turkish empires established after the collapse of these three vassal states. In fact, it can be said that even today, the historical anatomy of the ranks used in terms of status determination and the arrangement of the political field in different Islamic geographies is being explored. Most importantly, in this study, we try discover the cornerstones of the communication dimension of the mawali with the Arab power. The location of the Transoxiana and Khorasan geographies before the Islamic conquests and the population fluidity accelerated by the Turkish migrations were an important factor in the political formation of the region during the Abbasid period. The historical background was taken into consideration in the titles given to the vassal state rulers. It is remarkable that the caliph gave the old Turkish title “ıhsid” to a Turkish leader of a state established in Egypt. There are many other examles such as this with regard to the vassal states in the East. The conclusion we have obtained from our study is that titles play a decisive role in the political connection between the center of the caliphate and the affiliated states. On the one hand, this regulates the balance between the center and local administrators, on the other hand, it determines the moral as well as the material rank of the sultans in the eyes of the people. In fact, the successes in the conquests led the caliphs to rank the vassal sultans with titles. This situation is a kind of password that determines the balance between the religious authority, the caliphate, and the worldly authority. (shrink)

Barut's classicalzitterbewegung model includes the internal dynamical variables and the quantization of this system gives a general transition amplitude between the different space-time points and internal coordinates and momentum. It includes the transition amplitude between the half integer and integer spin eigenvalues. Spin eigenfunctions lead to all sets of relativistic wave equations, as well as the Dirac equation.

Barut's classical model of the spinning particle having external dynamical variables x and p and internal dynamical variables $\bar z$ and z is taken into account. The path integrations over holomorphic spinors $\bar z$ and z are discussed. This quantization gives the kernel of the relativistic particles with higher spin as well as the Dirac electron. The Green's function of the spin-n/2 particle is obtained.

The mutakallimūn, who began to take care of nature as a result of their metaphysical concerns from the early period and with the influence of the dualist and materialist groups, suggested various theories that attempt to explain the structure and functioning of the universe. Over time, many subjects of physics became an indispensable part of Kalām and were used in the proof of the fundamental principles. Thus, in addition to the definition of body (jism), Kalām books began to contain detailed (...) topics such as time, space, movement and distance. After summarizing the definitions of body, which were made by the mutakallimūn, this article will examine the contents of Ibn Kamāl's epistle on ṭafra (leaping), which has many copies with various titles in the Turkish Libraries. In the beginning of the epistle, Ibn Kamāl mentions the descriptions of body suggested by the prominent mutakallimūn, and then, he compares the views of al-Naẓẓām, who believes in the finite division, with atomist mutakallimūn who accept the infinite division. He criticizes the idea of ṭafra with regard to the notion of body in Kalām. After explaining the arguments of both groups with their justifications, he points out the weaknesses of the arguments of each group, as well. In this connection, he revisits the theory of ṭafra, which is, he argues, a mandatory consequence of al-Naẓẓām’s definition of object, as he also reviews the opinions of Quṭb al-Din al-Rāzī in this direction.

We extended the Barut’s classical model of zitterbewegung from 3+1 dimensional spacetime into 2+1 and 1+1 dimensional spacetimes and discussed the symmetry and integrability properties of the model in 2+1, 1+1 and 3+1 dimensions. In these cases, the free particle current or the velocity of the particle can be decomposed as a constant convection current and polarization currents.In 2+1 dimensional spacetime, a velocity of the particle and spin tensor are dependent to each other and the chirality can not be introduced. (...) The free particle has 7 constants of motion: The momentum three vector, the charge, the energy in proper time, the scalar constant spin or magnetic polarization and the two components of total angular momentum. Two component electric polarizations oscillate with Zitterbewegung frequency.In 1+1 dimensional spacetime we have an independent velocity vector and a scalar spin tensor. The free particle has 5 integrals of motion: The momentum two vector, the charge, the energy in proper time, and the scalar total angular momentum. The normal component of the velocity or the scalar electric polarization oscillates with Zitterbewegung frequency.In 3+1 dimensional spacetime, the particle has an independent velocity vector, spin tensor and chirality. The free particle has 12 integrals of motion: The momentum four vector, the charge, the energy in proper time or mass, the three vector spin or magnetic polarizations and three components of total angular momentum. The parallel component of velocity into momentum and the normal components of the spin tensor or the spin three vector are constants of motion for the free particle. The chirality and electric polarizations oscillate with the Zitterbewegung frequency. The system is superintegrable in all dimensions. (shrink)

We propose a simple classical model of the zitterbewegung. In this model spin is proportional to the velocity of the particle, the component parallel top is constant and the orthogonal components are oscillating with2p frequency. The quantization of the system gives wave equations for spin,0, 1/2, 1, 3/2,…, etc. respectively. These equations are convenient for massless particles. The wave equation of the spin-1, massless free particle is equivalent to the Maxwell equations and the state functions have a probability interpretation and (...) exhibit conserved current densities. The ground state has zero energy. (shrink)

Kelâm âlimleri “mûcize” kavramını iki farklı şekilde tarif etmişlerdir. Bunlardan ilkinde mûcize “Peygamber olduğunu ileri süren kimsenin elinde, onun doğruluğunu kanıtlamak için meydana gelen hârikulâde olay” şeklinde tanımlanmıştır. İkinci tarife göre ise mûcize: “Peygamberlik iddia eden bir zâtın elinde, inkârcılara meydan okuduğu bir sırada, kendisini doğrular mâhiyette, başkalarının benzerini yapamadıkları, Allah tarafından yaratılan, olağanüstü olay”lara verilen addır. Tanımlardan da anlaşılacağı üzere “mûcize” kelimesiyle genel olarak “hissî mûcize”lere işaret edilmektedir. Zaten “mûcize” teriminin kelâmî metinlerde yer almaya başladığı IV. yy. dan itibaren (...) genelde Hz. Peygamber’in (s) hissî mucizelerinin bulunup bulunmağı temelinde tartışmalar yaşanmıştır. Hatta Kur’ân’da yer verilen geçmiş peygamberlere ait hissî mucize örneklerinden hareketle mesele zaman zaman peygamberlerin hissî mucizelerinin birbiriyle yarıştırılması boyutuna kadar taşınmıştır. Tüm bu tartışma safahatında geçmişte ve günümüzde ihmal edilen, gözden kaçırılan ya da yeteri kadar değer verilmeyen -bizce en önemli ve bugün de gözle görülür, dost, düşman, insaf sahibi herkesin takdirle karşıladığı- mûcize örneği ise Hz. Peygamber’in topyekûn dinî ve siyasî alanda sergilediği insanları dönüştürme kabiliyetidir. Kaldı ki Hz. Peygamber’in bu türden sergilediği mûcize örnekleri geçmişte bir noktada yaşanmış ve misyonunu tamamlayarak tarihin dehlizlerinde kaybolmuş da değildir. Aksine bu dönüştürme ameliyesi nebevî prensiplerin ikâmesi ile asr-ı saadette ve sonrasında olduğu gibi günümüzde ve kıyamete kadar devam edecek olan zaman dilimlerinde de örnekliğini sürdürmeye ve fonksiyonunu icra etmeye devam edecektir. Hz. Peygamber’in başta Bedir Savaşı ve Hudeybiye Antlaşması olmak üzere birçok siyasî alanda yine bireysel ve toplumsal olarak içinde yaşadığı toplumun yüceltilip yükseltilmesinde olağanüstü bir başarı sağladığı yadsınamaz bir gerçektir. Elde ettiği başarıların kendisini hiçbir şekilde asıl hedefinden, tevhid merkezli yaşantısından uzaklaştırmaması, günün sonunda yine “rabbine şükreden bir kul” vasfını koruması onun şahsî kemâlinin ve vahye muhatap oluşunun en büyük göstergelerindendir. John William Draper (ö. 1882) gibi Batılı bilim insanlarına şu türden cümleleri kurduran en mühim sâik de kuşkusuz Hz. Peygamber’in sözünü ettiğimiz o eşsiz dönüştürme kabiliyetidir: “Tüm insanlar arasında, insan ırkına en fazla tesir eden kişi, Justinianus'un ölümünden dört yıl sonra Mekke’de, Arabistan'da doğan kişidir. Pek çok imparatorluğun manevî ve dinî lideri olmak, insan ırkının üçte birinin günlük hayatını yönlendirmek, belki de ‘Allah'ın Elçisi’ unvanının gerçek olduğunun delilidir.” İşte “Bir Mûcize Örneği Olarak Hz. Peygamber’in İnsanları Dönüştürme Kabiliyeti” başlığını taşıyan bu makale, müslüman toplumun kendi ekseninde yükselmesi ve yücelmesi adına hayatî önemi hâiz, günümüz insanının hayat felsefesine yön vermesi açısından da son derece kıymetli ve yol gösterici olan Son Elçi’nin bireyi, toplumu ve insanlığı dönüştürme kabiliyetini onun vahye muhatap kimliği ve tevhid eksenli hayatı çerçevesinde ortaya koymayı hedeflemektedir.

Öz: Son Peygamber Muhammed ’in hayatta iken yerine hiçbir kimseyi halife tayin etmemesi sebebiyle vefatından kısa bir müddet sonra imamet meselesi Müslümanlar arasında ihtilaf konusu olmuştur. Her ne kadar ilk üç halife devrinde bu mesele sulh yoluyla halledilmişse de halifenin kim olacağı mevzuu dördüncü halife Ali zamanında Müslümanlar arasında savaşa ve parçalanmalara neden olmuştur. O dönemde Müslümanlardan bir grup, Hz. Peygamberin kendisinden sonra yerine bir idareci bırakmadığı iddiasını kabul etmemiş, imametin Ali b. Ebî Tâlib’in ve onun evlatlarının hakkı olduğunu savunmuştur. (...) “Şiatu Ali” adıyla anılan bu gruba daha sonraki yıllarda sadece “Şia” denmiştir. İmamet mevzuu, Şia’yı diğer Müslüman grup olan Ehl-i Sünnet’ten ayıran en önemli meseledir. Onlara göre İmamet “Üsulu’d-Din”den olduğu için bu konuya oldukça önem vermiş ve görüşlerini desteklemek için ayet ve hadislerden deliller getirmişlerdir. Biz bu çalışmamızda, Şia’nın Ali b. Ebî Tâlib’in İmametiyle ilgili olduğunu iddia ettikleri ayetleri ele alacak, Şia’nın ve Ehl-i Sünnet’in iki büyük müfessiri Kummî ve İbn Kesîr’in tefsirleri çerçevesinde değerlendirmeye çalışacağız.

Purpose This paper aims to analyze the ways socio-economic issues are represented in mainstream news media and how it is consumed, understood and interpreted by Israeli young adults. It examines how mainstream media uses neo-liberal discourse, and the ways YAs internalize this ethic, while simultaneously finding ways to overcome its limitations. Design/methodology/approach This was a mixed methods study. First, it undertook content analysis of the most popular Israeli mainstream news media among YAs: the online news site Ynet and the TV (...) Channel 2 news. Second, the authors undertook semi-structured in-depth interviews with 29 Israeli YAs. The analysis is based on an online survey of 600 young Israelis, aged 18–35 years. Findings Most YAs did not perceive mainstream media as enabling a reliable understanding of the issues important to them. The content analysis revealed that self-representation of YAs is rare, and that their issues were explained, and even resolved, by older adults. Furthermore, most of YAs' problems in mainstream news media were presented using a neo-liberal perspective. Finally, from the interviews, the authors learned that YAs did not find information that could help them deal with their most pressing economic and social issue, in the content offered by mainstream media. For most of them, social media overcomes these shortcomings. Originality/value Contrary to research that has explored YAs’ consumerism of new media outlets, this article explores how YAs in Israel are constructed in the media, as well as the way in which YAs understand mainstream and new social media coverage of the issues most important to them. Using media content analysis and interviews, the authors found that Young Adults tend to be ambivalent toward media coverage. They understand the lack of media information: most of them know that they do not learn enough from the media. This acknowledgment accompanies their tendency to internalize the neo-liberal logic and conservative Israeli national culture, in which class and economic redistribution are largely overlooked. Mainstream news media uses neo-liberal discourse, and young adults internalize this logic, while simultaneously finding ways to overcome the limitations this discourse offers. They do so by turning to social media, mainly Facebook. Consequently, their behavior maintains the logic of the market, while also developing new social relations, enabled by social media. (shrink)

Bu çalışmada “tabiat” kavramının sözlük ve terim anlamı analiz edilmiş ve ona ilişkin bazı Meşşâî İslam filozoflarının görüşlerine yer verilmiştir. “Tabiat” sözcüğünü karşılamak üzere Türkçede kullanılan “tabiat” ve “doğa” sözcükleri arasında bir karşılaştırma yapılmıştır. “Tabiat”ın Meşşâî İslam filozofları tarafından isim olarak kullanıldığı varlık alanı hakkında bilgi verilmiş ve İbn Sina ile İbn Rüşd arasında cereyan eden tabiatın ispatının gerekip gerekmeyeceği tartışmasına değinilmiştir. Cisimlerde görülen hareket ve sükunun kaynağı olması bakımından “tabiat”ın nelere delalet ettiği hususunda İbn Sina’nın görüşleri Aristo ile mukayeseli (...) olarak sunulmuştur. Daha sonra bir terim olarak “tabiat”ın filozoflar tarafından yapılan tanımı ortaya konulmuştur. İslam felsefesinde önemli bir yere sahip olan “tabiat” kavramına Meşşâî İslam filozoflarının yükledikleri anlam ve onu kullanma biçimleri, Aristo’dan farklıdır. Özellikle her türlü oluş ve hareketin kaynağını açıklamak amacıyla kullandıkları “tabiat” kavramı etimolojik açıdan tüm nedenleri Allah’a ulaştırmaya imkan sağlamaktadır. Ayrıca kavramın, “tabiat – tabiat ötesi” ayrımına dayanak teşkil ettiği de bilinmektedir. Makalenin amacı, “tabiat” kavramının günümüzde yeni teorilerle ilişkili olarak kullanılma imkanlarını belirginleştirmektir. (shrink)

This paper is a literature review of Al-Farābi's thoughts on the urgency of the value of moderation in the discourse of sustainable development in Indonesia which is studied through his magnumopus entitled "Madīnah Al-Fāḍilah". By using a descriptive-analytical approach, it is concluded that the value of moderation is the main basis for understanding the role and existence of individuals to actualize a variety of sustainable development through the implementation of the 4 pillars of moderation in Al-Farābi's view, namely unity, deliberation, (...) mutual cooperation, and character. The four pillars of moderation in Al-Farābi's view seek to build the closeness of each individual in social life, in order to discuss solving various problems that hinder the factors of sustainable development. The implementation of the 4 pillars of moderation in Al-Farābi's view can be realized through the existence of a leader as an existence that influences the paradigm and behavior of people in a region. That is, leaders are here to unite people of various groups to realize their role and position in order to optimize the value of moderation as the basis for sustainable development in reality. The final result of this paper is to understand the application of Al-Farābi's value of moderation in welcoming sustainable development in Indonesia. (shrink)

The shortage of organs for transplantation by its nature prompts ethical dilemmas. For example, although there is an imperative to save human life and reduce suffering by maximising the supply of vital organs, there is an equally important obligation to ensure that the process by which we increase the supply respects the rights of all stakeholders. In a relatively unexamined practice in the USA, organs are procured from unrepresented decedents without their express consent. Unrepresented decedents have no known healthcare wishes (...) or advance care planning document; they also lack a surrogate. The Revised Uniform Anatomical Gift Act of 2006 sends a mixed message about the procurement of organs from this patient population and there are hospitals that authorise donation. In addition, in adopting the RUAGA, some states included provisions that clearly allow organ procurement from unrepresented decedents. An important unanswered question is whether this practice meets the canons of ethical permissibility. The current Brief Report presents two principled approaches to the topic as a way of highlighting some of the complexities involved. Concluding remarks offer suggestions for future research and discussion. (shrink)

This study investigates the role of advantageous comparisons and professional commitment in earning management rationalization. Our study adopted a laboratory between-subject experimental design with 139 accounting students. The results show that advantageous comparisons and professional commitment affect the rationalization of earning management actions. Moreover, compared to participants with high levels of professional commitment, those with low levels of professional commitment view earning management as a more appropriate action when they are engaged in earning management and viewing the egregious example of (...) that action. This finding is important because it explains how personal psychological factors affect the ethical cognitive processes of accountants. This study complements the lack of previous studies and argues that the propensity to compare acts of delinquency depends on an individual's commitment to their profession. We also emphasize the importance of investigating this issue outside of the US context. The results of this study may be helpful to managers, practitioners, academics, and accounting researchers with a better understanding of the potential impact of exposure to earning management practices and an individual’s professional commitment to earning management behaviour. Further, based on this study, all stakeholders may be better positioned to suggest possible remedies and mitigate these behaviours. (shrink)
