PLUTO’S DISCOVERY

On February 18, 1930, American astronomer Clyde Tombaugh discovered Pluto. For
more than 75 years, it was regarded as the ninth planet in the solar system
(before being downgraded to a dwarf planet in 2006). How much do you know about

“A GRAVE INJUSTICE”

On February 19, 1942, U.S. Pres. Franklin D. Roosevelt signed Executive Order
9066, authorizing the secretary of war “to prescribe military areas in such
places and of such extent as he or the appropriate Military Commander may
determine, from which any or all persons may be excluded.” While the order did
not specify any particular group or individuals, it was soon applied to
virtually the entire Japanese American population on the West Coast. Some
120,000 Japanese Americans were deprived of their possessions and livelihoods
and detained in prison camps for up to three years. The order would not be
formally repealed until 1976.

BANNED BOOKS

Maus

Art Spiegelman’s Pulitzer Prize-winning masterpiece has been banned by a
Tennessee school district after school board members drew attention to a handful
of “curse words” and a picture of a “naked” mouse. Spiegelman described the move
as “Orwellian” and characterized the board’s objections as “Why can’t they teach
a nicer Holocaust?”

Stamped: Racism, Antiracism, and You

MacArthur fellow Ibram X. Kendi has been a frequent target of book-banning
efforts, and his young adult antiracism primer Stamped (written with Jason
Reynolds) was the second-most challenged book in American libraries in 2020. In
2021, as states passed laws banning the teaching of critical race theory (an
analytical framework that is only taught at the university level and above),
challenges to Black authors increased dramatically.

Geography & Travel
Planet Earth contains some extraordinarily diverse environments, some of which
are easily habitable and some not so much. In different areas of Earth, one
might find sweltering deserts, dense tropical rainforests, or bone-chilling
tundras. Each biome and habitat comes with its own selection of flora and fauna,
and it may include physical features such as canyons, volcanoes, rivers, or
caves. Human beings have built homes in many different environments, settling
the area and organizing it into units such as cities, states, regions, and
countries, each with its own points of interest. Shifting trends in human
migration have resulted in a human geography that is profoundly different from
that of centuries ago.

Lifestyles & Social Issues
It's easy enough to agree that human beings all around the world have certain
basic requirements that must be fulfilled in order to ensure their individual
and collective well-being. History has shown us, however, that it's not so easy
to form societies or communities that fulfill these requirements for all
members. The fight for human and civil rights has persisted for hundreds of
years and remains alive today, both within the borders of nations and on an
international scale. It has led to large-scale social movements and reforms
concerning issues such as suffrage, slavery, women's rights, racism,
environmentalism, gay rights, and much more.

other genres. Through literature, communication becomes an art, and it can
bridge and bond people and cultures of different languages and backgrounds.

Philosophy & Religion
Humans have long pondered not only how we came to be but also why we came to be.
The earliest Greek philosophers focused their attention upon the origin and
nature of the physical world; later philosophers have theorized about the nature
of knowledge, truth, good and evil, love, friendship, and much more. Philosophy
involves a methodical assessment of any and all aspects of human existence and
experience. The realms of philosophy and religion have sometimes intersected in
conducting such inquiries as these. As with philosophy, the study of religion
underscores how humankind has long speculated about its origins. The possibility
of a higher being (or beings) to which livings things owe their existence has
long captived human thought. Many religions also offer their own views on the
nature of good and evil, and they may prescribe guidelines and judgment on
different kinds of human behavior.

Politics, Law & Government
The world today is divided territorially into more than 190 countries, each of
which possesses a national government that claims to exercise sovereignty and
seeks to compel obedience to its will by its citizens. Governments can be
classified in any number of ways. For example, they might be classified by the
number of rulers, thus distinguishing government by one (as in a monarchy or a
tyranny) from government by the few (in an aristocracy or oligarchy) and from
government by the many (as in a democracy). Governments can also be classified
by mode of succession; for example, ascension to governmental leadership may
follow the rules of hereditary succession, or it may be determined through
elections or by force. Governments also vary in terms of the laws and rules of
conduct that each political entity follows.

Science
How can the sky be blue one day and stormy the next? Why do heavy objects tend
to fall downwards when dropped? How are birds able to fly (and why can�t I do
the same?)? Human beings have long been curious about the world in which we
live, striving to identify connections among the phenomenons we witness and to
understand how it all works. The field of science has developed over many
centuries as a way of studying and understanding the world, beginning with the
primitive stage of simply noting important regularities in nature and continuing
through the rise of modern science. The modern-day sciences cover a vast range
of fields, including biology, chemistry, meteorology, astronomy, physics, and
much more.

Sports & Recreation
Physical contests and recreational games have long played a part in human
society. In both team and solo sports, the human body has been pushed to its
limits in the name of improving athletic performance and in order to break
record upon record. The ancient Olympic Games are an early example of the
contests in which humans have engaged to showcase physical prowess. In modern
times, sports and games have evolved into a lucrative and competitive industry,
while other leisure activities, such as card and video games, can be competitive
or just serve as a way to unwind or socialize.

significant inventions have been made throughout history that in turn made a

Though beauty is in the eye of the beholder, different eras in art history have
had their own principles to define beauty, from the richly ornamented taste of
the Baroque to the simple utilitarian style of the Prairie School.
