Coronaviruses (are a group of RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS, and COVID-19)

Doppler radar - is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, Major League Baseball's StatCast system, meteorology, radar guns, radiology and healthcare (fall detection and risk assessment, nursing or clinic purpose), and bistatic radar (surface-to-air missiles).

Partly because of its common use by television meteorologists in on-air weather reporting, the specific term "Doppler Radar" has erroneously become popularly synonymous with the type of radar used in meteorology. Most modern weather radars use the pulse-Doppler technique to examine the motion of precipitation, but it is only a part of the processing of their data. So, while these radars use a highly specialized form of Doppler radar, the term is much broader in its meaning and its applications.

Extinction Events ((also known as a mass extinction or biotic crisis) is a widespread and rapid decrease in the biodiversity on Earth. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Estimates of the number of major mass extinctions in the last 540 million years range from as few as five to more than twenty. These differences stem from the threshold chosen for describing an extinction event as "major", and the data chosen to measure past diversity)

Facebook (stylized as facebook) - is an American online social media and social networking service based in Menlo Park, California, and a flagship service of the namesake company Facebook, Inc. It was founded by Mark Zuckerberg, along with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.

Break ... I need to get some dinner and it's almost time for MC.

Gilded Age (was an era that occurred during the late 19th century, from the 1870s to about 1900. The Gilded Age was an era of rapid economic growth, especially in the Northern United States and the Western United States. As American wages grew much higher than those in Europe, especially for skilled workers, the period saw an influx of millions of European immigrants. The rapid expansion of industrialization led to a real wage growth of 60%, between 1860 and 1890, and spread across the ever-increasing labor force. The average annual wage per industrial worker (including men, women, and children) rose from $380 in 1880, to $564 in 1890, a gain of 48%. Conversely, the Gilded Age was also an era of abject poverty and inequality, as millions of immigrants—many from impoverished regions—poured into the United States, and the high concentration of wealth became more visible and contentious)

Hurricane - is a tropical cyclone with sustained winds of at least 74 mph that occurs in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or eastern Pacific Ocean. A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls.

Ice Age (is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation, known in popular terminology as the Ice Age. Individual pulses of cold climate within an ice age are termed "glacial periods" (or, alternatively, "glacials", "glaciations", "glacial stages", "stadials", "stades", or colloquially, "ice ages"), and intermittent warm periods within an ice age are called "interglacials" or "interstadials", with both climatic pulses part of the Quaternary or other periods in Earth's history)

Jersey Boys - is a 2005 jukebox musical with music by Bob Gaudio, lyrics by Bob Crewe, and book by Marshall Brickman and Rick Elice. It is presented in a documentary-style format that dramatizes the formation, success and eventual break-up of the 1960s rock 'n' roll group The Four Seasons. The musical is structured as four "seasons", each narrated by a different member of the band who gives his own perspective on its history and music. The musical ran on Broadway from 2005 to 2017, and since its debut it has been on two North American national tours and two national tours of The UK and Ireland.  Jersey Boys won four 2006 Tony Awards including Best Musical, and the 2009 Laurence Olivier Award for Best New Musical. Songs include "Big Girls Don't Cry", "Sherry", "December 1963 (Oh, What A Night)", "My Eyes Adored You", "Stay", "Can't Take My Eyes Off You", "Who Loves You", "Working My Way Back to You" and "Rag Doll", among others.

There also a 2014 movie based on the musical

Knights of the Round Table (are the knights in the fellowship of King Arthur in the literary cycle of the Matter of Britain, first appearing in literature in the mid 12th century. In this French-derived branch of Arthurian legend, the Knights are an order in the service of King Arthur, tasked with ensuring the peace of the kingdom and later leading the quest for the legendary Holy Grail. The Round Table, the place at which these characters of legend meet is a symbol of equality, and all members of the round table are thus, equal)

Longitude, is a geographic coordinate that specifies the east–west position of a point on the Earth's surface, or the surface of a celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda. Meridians connect points with the same longitude
