Here is a question about this article: 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.
What is the answer to this question: Quantum field theory suggest what is the main substance?

So... fields


Here is a question about this article: Samkhya philosophy includes a theory of gunas (qualities, innate tendencies, psyche). Guna, it states, are of three types: Sattva being good, compassionate, illuminating, positive, and constructive; Rajas guna is one of activity, chaotic, passion, impulsive, potentially good or bad; and Tamas being the quality of darkness, ignorance, destructive, lethargic, negative. Everything, all life forms and human beings, state Samkhya scholars, have these three gunas, but in different proportions. The interplay of these gunas defines the character of someone or something, of nature and determines the progress of life. Samkhya theorises a pluralism of souls (Jeevatmas) who possess consciousness, but denies the existence of Ishvara (God). Classical Samkhya is considered an atheist / non-theistic Hindu philosophy.
What is the answer to this question: Which state of guna is that of compassion, positiveness, and goodness?

So... Sattva


Here is a question about this article: Tucson has a desert climate (Köppen BWh), with two major seasons, summer and winter; plus three minor seasons: fall, spring, and the monsoon. Tucson averages 11.8 inches (299.7 mm) of precipitation per year, more than most other locations with desert climates, but it still qualifies due to its high evapotranspiration; in other words, it experiences a high net loss of water. A similar scenario is seen in Alice Springs, Australia, which averages 11 inches (279.4 mm) a year, but has a desert climate.
What is the answer to this question: Which Australian town has a similar climate as Tucson?

So...
Alice Springs
