Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
Regarding atoms, what does the Planck constant imply?
that only certain energy levels are allowed

Input: Federalism
In almost all federations the central government enjoys the powers of foreign policy and national defense as exclusive federal powers. Were this not the case a federation would not be a single sovereign state, per the UN definition. Notably, the states of Germany retain the right to act on their own behalf at an international level, a condition originally granted in exchange for the Kingdom of Bavaria's agreement to join the German Empire in 1871. Beyond this the precise division of power varies from one nation to another. The constitutions of Germany and the United States provide that all powers not specifically granted to the federal government are retained by the states. The Constitution of some countries like Canada and India, on the other hand, state that powers not explicitly granted to the provincial governments are retained by the federal government. Much like the US system, the Australian Constitution allocates to the Federal government (the Commonwealth of Australia) the power to make laws about certain specified matters which were considered too difficult for the States to manage, so that the States retain all other areas of responsibility. Under the division of powers of the European Union in the Lisbon Treaty, powers which are not either exclusively of European competence or shared between EU and state as concurrent powers are retained by the constituent states.

Per the UN definition, what is federalism?
Output: federation would not be a single sovereign state

Input: Article: Although there is evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans after the invasion of 43 AD. This lasted only until around 61, when the Iceni tribe led by Queen Boudica stormed it, burning it to the ground. The next, heavily planned, incarnation of Londinium prospered, and it superseded Colchester as the capital of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of around 60,000.

Now answer this question: What was the capital of Britannia before Londinium?

Output: Colchester

Article: On November 17, 1987, SCA acquired CBS Records, which hosted such acts as Michael Jackson, for US$2 billion. CBS Inc., now CBS Corporation, retained the rights to the CBS name for music recordings but granted Sony a temporary license to use the CBS name. CBS Corporation founded a new CBS Records in 2006, which is distributed by Sony through its RED subsidiary.

Question: How much did SCA pay for CBS Records?
Ans: $2 billion

Here is a question about this article: Modern Orthodoxy comprises a fairly broad spectrum of movements, each drawing on several distinct though related philosophies, which in some combination have provided the basis for all variations of the movement today. In general, Modern Orthodoxy holds that Jewish law is normative and binding, while simultaneously attaching a positive value to interaction with contemporary society. In this view, Orthodox Judaism can "be enriched" by its intersection with modernity; further, "modern society creates opportunities to be productive citizens engaged in the Divine work of transforming the world to benefit humanity". At the same time, in order to preserve the integrity of halakha, any area of "powerful inconsistency and conflict" between Torah and modern culture must be avoided. Modern Orthodoxy, additionally, assigns a central role to the "People of Israel".
What is the answer to this question: What kind of work does orthodox Judiasm seek to transform the world with?
****
So... Divine work

Article: Milton Winternitz led the Yale Medical School as its dean from 1920 to 1935. Dedicated to the new scientific medicine established in Germany, he was equally fervent about "social medicine" and the study of humans in their culture and environment. He established the "Yale System" of teaching, with few lectures and fewer exams, and strengthened the full-time faculty system; he also created the graduate-level Yale School of Nursing and the Psychiatry Department, and built numerous new buildings. Progress toward his plans for an Institute of Human Relations, envisioned as a refuge where social scientists would collaborate with biological scientists in a holistic study of humankind, unfortunately lasted for only a few years before the opposition of resentful anti-Semitic colleagues drove him to resign.

Question: What teaching style did Milton Winternitz develop?
Ans:
Yale System
