Problem: Gautama was now determined to complete his spiritual quest. At the age of 35, he famously sat in meditation under a Ficus religiosa tree now called the Bodhi Tree in the town of Bodh Gaya and vowed not to rise before achieving enlightenment. After many days, he finally destroyed the fetters of his mind, thereby liberating himself from the cycle of suffering and rebirth, and arose as a fully enlightened being (Skt. samyaksambuddha). Soon thereafter, he attracted a band of followers and instituted a monastic order. Now, as the Buddha, he spent the rest of his life teaching the path of awakening he had discovered, traveling throughout the northeastern part of the Indian subcontinent, and died at the age of 80 (483 BCE) in Kushinagar, India. The south branch of the original fig tree available only in Anuradhapura Sri Lanka is known as Jaya Sri Maha Bodhi.
What town was the Bodhi Tree in?
The answer is the following: Bodh Gaya

Problem: Infrared reflectography (fr; it; es), as called by art conservators, can be applied to paintings to reveal underlying layers in a completely non-destructive manner, in particular the underdrawing or outline drawn by the artist as a guide. This often reveals the artist's use of carbon black, which shows up well in reflectograms, as long as it has not also been used in the ground underlying the whole painting. Art conservators are looking to see whether the visible layers of paint differ from the underdrawing or layers in between such alterations are called pentimenti when made by the original artist. This is very useful information in deciding whether a painting is the prime version by the original artist or a copy, and whether it has been altered by over-enthusiastic restoration work. In general, the more pentimenti the more likely a painting is to be the prime version. It also gives useful insights into working practices.
What is the term for differences in the painting and underdrawing made by the original artist?
The answer is the following: pentimenti

Problem: The period known as classical antiquity began with the rise of the city-states of Ancient Greece. Greek influence reached its zenith under the expansive empire of Alexander the Great, spreading throughout Asia.
Who was responsible for the bringing Greek culture as far as Asia?
The answer is the following: Alexander the Great

Problem: In quantum mechanics, energy is defined in terms of the energy operator as a time derivative of the wave function. The Schrodinger equation equates the energy operator to the full energy of a particle or a system. Its results can be considered as a definition of measurement of energy in quantum mechanics. The Schrodinger equation describes the space- and time-dependence of a slowly changing (non-relativistic) wave function of quantum systems. The solution of this equation for a bound system is discrete (a set of permitted states, each characterized by an energy level) which results in the concept of quanta. In the solution of the Schrodinger equation for any oscillator (vibrator) and for electromagnetic waves in a vacuum, the resulting energy states are related to the frequency by Planck's relation: (where is Planck's constant and the frequency). In the case of an electromagnetic wave these energy states are called quanta of light or photons.
What describes the space-and-time dependence of a slowly changing wave function of quantum systems?
The answer is the following:
The Schrodinger equation
