The Spanish ship San Pedro and two other vessels in an expedition commanded by Miguel Lopez de Legazpi discovered an island on January 9, 1530, possibly Mejit, at 10N, which they named "Los Barbudos". The Spaniards went ashore and traded with the local inhabitants. On January 10, the Spaniards sighted another island that they named "Placeres", perhaps Ailuk; ten leagues away, they sighted another island that they called "Pajares" (perhaps Jemo). On January 12, they sighted another island at 10N that they called "Corrales" (possibly Wotho). On January 15, the Spaniards sighted another low island, perhaps Ujelang, at 10N, where they described the people on "Barbudos". After that, ships including the San Jeronimo, Los Reyes and Todos los Santos also visited the islands in different years.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What island may have been spotted by the Spanish on January 15?
Ah, so.. Ujelang

Richard Hagopian is perhaps the most famous artist of the traditional "kef" style and the Vosbikian Band was notable in the 1940s and 1950s for developing their own style of "kef music" heavily influenced by the popular American Big Band Jazz of the time. Later, stemming from the Middle Eastern Armenian diaspora and influenced by Continental European (especially French) pop music, the Armenian pop music genre grew to fame in the 1960s and 1970s with artists such as Adiss Harmandian and Harout Pamboukjian performing to the Armenian diaspora and Armenia; also with artists such as Sirusho, performing pop music combined with Armenian folk music in today's entertainment industry.

Ah, so.. Richard Hagopian

One challenge to the traditional concept of matter as tangible "stuff" came with the rise of field physics in the 19th century. Relativity shows that matter and energy (including the spatially distributed energy of fields) are interchangeable. This enables the ontological view that energy is prima materia and matter is one of its forms. On the other hand, the Standard Model of Particle physics uses quantum field theory to describe all interactions. On this view it could be said that fields are prima materia and the energy is a property of the field.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Relativity says that what is not interchangeable?
Ah, so..
unanswerable
