Buddhism and science have increasingly been discussed as compatible, and Buddhism has entered into the science and religion dialogue. The case is made that the philosophic and psychological teachings within Buddhism share commonalities with modern scientific and philosophic thought. For example, Buddhism encourages the impartial investigation of Nature (an activity referred to as Dhamma-Vicaya in the Pali Canon) — the principal object of study being oneself. Some popular conceptions of Buddhism connect it to discourse regarding evolution, quantum theory, and cosmology, though most scientists see a separation between the religious and metaphysical statements of Buddhism and the methodology of science.^{[citation needed]}

Buddhism has been described by some as rational and non-dogmatic, and there is evidence that this has been the case from the earliest period of its history, though some have suggested this aspect is given greater emphasis in modern times and is in part a reinterpretation. Not all forms of Buddhism eschew dogmatism, remain neutral on the subject of the supernatural, or are open to scientific discoveries. Buddhism is a varied tradition and aspects include fundamentalism, devotional traditions, supplication to local spirits, and various superstitions. Nevertheless, certain commonalities have been cited between scientific investigation and Buddhist thought. Tenzin Gyatso, the 14th Dalai Lama, in a speech at the meeting of the Society for Neuroscience, listed a "Suspicion of absolutes" and a reliance on causality and empiricism as common philosophical principles shared between Buddhism and science.

Alan Wilson Watts (6 January 1915 – 16 November 1973) was a British philosopher, writer, and speaker, best known as an interpreter and populariser of Eastern philosophy for a Western audience. Born in Chislehurst, he moved to the United States in 1938 and began Zen training in New York. Pursuing a career, he attended Seabury-Western Theological Seminary, where he received a master's degree in theology. Watts became an Episcopal priest but left the ministry in 1950 and moved to California, where he joined the faculty of the American Academy of Asian Studies.

Living on the West Coast, Watts gained a large following in the San Francisco Bay Area while working as a volunteer programmer at KPFA, a Pacifica Radio station in Berkeley. Watts wrote more than 25 books and articles on subjects important to Eastern and Western religion, introducing the then-burgeoning youth culture to The Way of Zen (1957), one of the first bestselling books on Buddhism. In Psychotherapy East and West (1961), Watts proposed that Buddhism could be thought of as a form of psychotherapy and not just a religion. Like Aldous Huxley before him, he explored human consciousness in the essay, "The New Alchemy" (1958), and in the book, The Joyous Cosmology (1962).

Ajahn Brahmavamso Mahathera (known to most as Ajahn Brahm), born Peter Betts in London, United Kingdom on 7 August 1951, is a Theravada Buddhist monk. Currently Brahm is the Abbot of Bodhinyana Monastery, in Serpentine, Western Australia, the Spiritual Director of the Buddhist Society of Western Australia, Spiritual Adviser to the Buddhist Society of Victoria, Spiritual Adviser to the Buddhist Society of South Australia, Spiritual Patron of the Buddhist Fellowship in Singapore, and Spiritual Patron of the Bodhikusuma Centre in Sydney.

Peter Betts came from a working-class background and went to Latymer Upper School. He won a scholarship to study Theoretical physics at Cambridge University in the late 1960s. After graduating from Cambridge he taught in high school for one year before traveling to Thailand to become a monk and train with the Ajahn Chah Bodhinyana Mahathera. Brahm was ordained in Bangkok at the age of twenty-three by the Abbot of Wat Saket. He subsequently spent nine years studying and training in the forest meditation tradition under Ajahn Chah.

Albert Einstein ( /ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics. While best known for his mass–energy equivalence formula E = mc² (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory within physics.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.

The Dalai Lama is a high lama in the Gelug or "Yellow Hat" branch of Tibetan Buddhism. The name is a combination of the Sino-Mongolian word далай (dalai) meaning "Ocean" and the Tibetan word བླ་མ་ bla-ma (with a silent "b") meaning "chief, high priest".

In religious terms, the Dalai Lama is believed by his devotees to be the rebirth of a long line of tulkus who are considered to be manifestations of the bodhisattva of compassion, Avalokiteśvara. Traditionally, the Dalai Lama is thought of as the latest reincarnation of a series of spiritual leaders who have chosen to be reborn in order to enlighten others. The Dalai Lama is often thought to be the leader of the Gelug School, but this position belongs officially to the Ganden Tripa, which is a temporary position appointed by the Dalai Lama who, in practice, exerts much influence. The line of Dalai Lamas began as a lineage of spiritual teachers; the 5th Dalai Lama assumed political authority over Tibet.

For certain periods between the 17th century and 1959, the Dalai Lamas sometimes directed the Tibetan government, which administered portions of Tibet from Lhasa. The 14th Dalai Lama remained the head of state for the Central Tibetan Administration ("Tibetan government in exile") until his retirement on March 14, 2011. He has indicated that the institution of the Dalai Lama may be abolished in the future, and also that the next Dalai Lama may be found outside Tibet and may be female. The Chinese government was very quick to reject this and claimed that only it has the authority to select the next Dalai Lama.
