Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world.[1][2] Modern science is typically divided into three major branches:[3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies;[4][5] and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.[6][7] There is disagreement whether the formal sciences are science disciplines,[8][9][10] as they do not rely on empirical evidence.[11][9] Applied sciences are disciplines that use scientific knowledge for practical purposes, such as in engineering and medicine.[12][13][14]

{{Excerpt|Aristotle}}

Roman copy (in marble) of a Greek bronze bust of Aristotle by Lysippos (c. 330 BC), with modern alabaster mantle

Aristotle[A] (Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BC) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.

Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At 17 or 18, he joined Plato's Academy in Athens and remained there until the age of 37 (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls.

Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication. Aristotle provided a complex synthesis of the various philosophies existing prior to him. His teachings and methods of inquiry have had a significant impact across the world, and remain a subject of contemporary philosophical discussion.

Aristotle's views profoundly shaped medieval scholarship. The influence of his physical science extended from late antiquity and the Early Middle Ages into the Renaissance, and was not replaced systematically until the Enlightenment and theories such as classical mechanics were developed. He influenced Judeo-Islamic philosophies during the Middle Ages, as well as Christian theology, especially the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church.

Aristotle was revered among medieval Muslim scholars as "The First Teacher", and among medieval Christians like Thomas Aquinas as simply "The Philosopher", while the poet Dante called him "the master of those who know". His works contain the earliest known formal study of logic, and were studied by medieval scholars such as Peter Abelard and Jean Buridan. Aristotle's influence on logic continued well into the 19th century. In addition, his ethics, although always influential, gained renewed interest with the modern advent of virtue ethics.

Weekly confirmed COVID-19 deaths
Map of cumulative COVID-19 death rates by U.S. state[1]

In the United States, the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in 103,436,829[2] confirmed cases with 1,186,533[2] all-time deaths, the most of any country, and the 20th highest per capita worldwide.[3] The COVID-19 pandemic is the deadliest disaster in the country's history.[4]

It was the third-leading cause of death in the U.S. in 2020, behind heart disease and cancer.[5] From 2019 to 2020, U.S. life expectancy dropped by 3 years for Hispanic and Latino Americans, 2.9 years for African Americans, and 1.2 years for white Americans.[6] In 2021, U.S. deaths due to COVID-19 rose[7] and life expectancy fell.[8]

The first American case was reported on January 20,[9] and President Donald Trump declared the U.S. outbreak a public health emergency on January 31. Restrictions were placed on flights arriving from China,[10][11] but the initial U.S. response to the pandemic was otherwise slow, in terms of preparing the healthcare system, stopping other travel, and testing.[12][13][14][a][16]

The first known American deaths occurred in February. On March 6, 2020, Trump allocated $8.3 billion to fight the outbreak and declared a national emergency on March 13. The government also purchased large quantities of medical equipment, invoking the Defense Production Act of 1950 to assist.[17] By mid-April, disaster declarations were made by all states and territories as they all had increasing cases. A second wave of infections began in June, following relaxed restrictions in several states, leading to daily cases surpassing 60,000. By mid-October, a third surge of cases began; there were over 200,000 new daily cases during parts of December 2020 and January 2021.[18][19]

COVID-19 vaccines became available in December 2020, under emergency use, beginning the national vaccination program, with the first vaccine officially approved by the Food and Drug Administration (FDA) on August 23, 2021.[20] Studies have shown them to be highly protective against severe illness, hospitalization, and death. In comparison with fully vaccinated people, the CDC found that those who were unvaccinated were from 5 to nearly 30 times more likely to become either infected or hospitalized. There has nonetheless been some vaccine hesitancy for various reasons, although side effects are rare.[21][22] There have also been numerous reports that unvaccinated COVID-19 patients have strained the capacity of hospitals throughout the country, forcing many to turn away patients with life-threatening diseases.

A fourth rise in infections began in March 2021 amidst the rise of the Alpha variant, a more easily transmissible variant first detected in the United Kingdom. That was followed by a rise of the Delta variant, an even more infectious mutation first detected in India, leading to increased efforts to ensure safety. The January 2022 emergence of the Omicron variant, which was first discovered in South Africa, led to record highs in hospitalizations and cases in early 2022, with as many as 1.5 million new infections reported in a single day.[23] By the end of 2022, an estimated 77.5% of Americans had had COVID-19 at least once, according to the CDC.[24]

State and local responses to the pandemic during the public health emergency included the requirement to wear a face mask in specified situations (mask mandates), prohibition and cancellation of large-scale gatherings (including festivals and sporting events), stay-at-home orders, and school closures.[25] Disproportionate numbers of cases have been observed among Black and Latino populations,[26][27][28] as well as elevated levels of vaccine hesitancy,[29][30] and there was a sharp increase in reported incidents of xenophobia and racism against Asian Americans.[31][32] Clusters of infections and deaths have occurred in many areas.[b] The COVID-19 pandemic also led to misinformation and conspiracy theories[35] and highlighted weaknesses in the U.S. public health system.[16][36][37]

Map of Belgium and its provinces with the spread of COVID-19 as of 9 July 2020[1]

The COVID-19 pandemic in Belgium has resulted in 4,861,393[2] confirmed cases of COVID-19 and 34,339[2] deaths.

The virus was confirmed to have spread to Belgium on 4 February 2020, when one of a group of nine Belgians repatriated from Wuhan to Brussels was reported to have tested positive for the coronavirus.[3][4] Transmission within Belgium was confirmed in early March; authorities linked this to holidaymakers returning from Northern Italy at the end of the half-term holidays.[5][6] The epidemic increased rapidly in March–April 2020. By the end of March all 10 provinces of the country had registered cases.[citation needed]

By March 2021, Belgium had the third highest number of COVID-19 deaths per head of population in the world, according to data compiled by Johns Hopkins University. However, Belgium may have been over-reporting the number of cases, with health officials reporting that suspected cases were being reported along with confirmed cases.[7] Unlike some countries that publish figures based primarily on confirmed hospital deaths, the death figures reported by the Belgian authorities included deaths in the community, such as in care homes, confirmed to have been caused by the virus, as well as a much larger number of such deaths suspected to have been caused by the virus, even if the person was not tested.[8]

Housing, or more generally, living spaces, refers to the construction and assigned usage of houses or buildings individually or collectively, for the purpose of shelter. Housing is a basic human need, and it plays a critical role in shaping the quality of life for individuals, families, and communities. [1]

Industrialization brought mass migration to cities. This one-room worker home from Helsinki from 1911 represents an attempt by the city government to improve the conditions of workers e.g. with electricity and running water installed in the row house.
