Termed "the acoustic equivalent to Prozac", soft adult contemporary, a more adult-oriented version of AC, was born in the late 1970s and grew in the early 1980s. WEEI-FM in Boston was the first station to use the term "soft rock", with ad slogans such as, "Fleetwood Mac ... without the yack" and "Joni ... without the baloney". The vast majority of music played on soft AC stations is mellow, more acoustic, and primarily solo vocalists.

Other popular names for the format include "Warm", "Sunny", "Bee" (or "B") and (particularly in Canada) "EZ Rock". The format can be seen as a more contemporary successor to and combination of the middle of the road (MOR), beautiful music, easy listening and soft rock formats. Many stations in the soft AC format capitalize on its appeal to office workers (many of them females aged 25–54, a key advertiser demographic), and brand themselves as stations "everyone at work can agree on" (KOST originated that phrase as a primary tagline, and other soft AC stations have followed suit).

A large portion of music played on this format are either considered oldies or recurrent. It often deals with modern romantic and sexual relationships (and sometimes other adult themes such as work, raising children, and family) in a thoughtful and complex way. Soft AC, which has never minded keeping songs in high rotation literally for years in some cases, does not appear necessarily to be facing similar pressures to expand its format. Soft AC includes a larger amount of older music, especially classic R&B, soul, and 1960s and 1970s music, than hot AC.

The soft AC format may soon be facing the demographic pressures that the jazz and big band formats faced in the 1960s and 1970s and that the oldies format is starting to face today, with the result that one may hear soft AC less on over-the-air radio and more on satellite radio systems in coming years. Much of the music and artists that were traditionally played on soft AC stations have been relegated to the adult standards format, which is itself disappearing because of aging demographics. Some soft AC stations have found a niche by incorporating more oldies into their playlists and are more open to playing softer songs that fit the "traditional" definition of AC.

Modern adult contemporary can be a variation of hot AC, and includes modern rock titles in its presentation. In 1997, Mike Marino of KMXB in Las Vegas described the format as reaching "an audience that has outgrown the edgier hip-hop or alternative music but hasn't gotten old and sappy enough for the soft ACs." The format's artists included Alanis Morissette, Counting Crows, Gin Blossoms, Bon Jovi, Train, No Doubt, The Script, The Cranberries, Lifehouse, Sarah McLachlan, Sara Bareilles, John Mayer, Jewel, and Ingrid Michaelson.

Adult contemporary R&B may be played on both soft AC stations and urban AC. It is a form of neo soul R&B that places emphasis on songcraft and sophistication. As the use of drum machines, synthesizers, and sequencers dominates R&B-rooted music, adult contemporary R&B tends to take most of its cues from the more refined strains of 1970s soul, such as smooth soul, Philly soul and quiet storm. Classic songwriting touches and organic-leaning instrumentation, often featuring string arrangements and horn charts, were constants.

In the 1980s, lush jazz-R&B fusion (George Benson, Patti Austin, Al Jarreau) and stylish crossover R&B (Anita Baker and Luther Vandross, New Edition and Keith Sweat) were equally successful within the mainstream. In the 1990s and early 2000s (decade), artists as sonically contrasting as R. Kelly, Leona Lewis (mainly ballads) and Jill Scott both fit the bill, provided the audience for the material was mature. By riding and contributing to nearly all of the trends, no one has exemplified the style more than Babyface, whose career thrived over 20 years as a member of the Deele (Two Occasions), a solo artist (Whip Appeal, When Can I See You), and a songwriter/producer (Toni Braxton's Breathe Again, Boyz II Men's I'll Make Love to You).

In recent years it has become common for many AC stations, particularly soft AC stations, to play primarily or exclusively Christmas music during the Christmas season in November and December. While these tend mostly to be contemporary seasonal recordings by the same few artists featured under the normal format, most stations will also air some vintage holiday tunes from older pop, MOR, and adult standards artists – such as Nat King Cole, Bing Crosby, Dean Martin, The Carpenters, Percy Faith, Johnny Mathis and Andy Williams – many of whom would never be played on these stations during the rest of the year.

Before the 20th century, the term matter included ordinary matter composed of atoms and excluded other energy phenomena such as light or sound. This concept of matter may be generalized from atoms to include any objects having mass even when at rest, but this is ill-defined because an object's mass can arise from its (possibly massless) constituents' motion and interaction energies. Thus, matter does not have a universal definition, nor is it a fundamental concept in physics today. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.

A: at rest']
All the objects from everyday life that we can bump into, touch or squeeze are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons. Typically, science considers these composite particles matter because they have both rest mass and volume. By contrast, massless particles, such as photons, are not considered matter, because they have neither rest mass nor volume. However, not all particles with rest mass have a classical volume, since fundamental particles such as quarks and leptons (sometimes equated with matter) are considered "point particles" with no effective size or volume. Nevertheless, quarks and leptons together make up "ordinary matter", and their interactions contribute to the effective volume of the composite particles that make up ordinary matter.

Questions and answers:
['
Q: What kind of particles make up every object in the world that can be touched?
A: atoms', '

Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).

Matter should not be confused with mass, as the two are not quite the same in modern physics. For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems. However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved. Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems. However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.

Questions and answers:
['
Q: What similar term is often used interchangeably with matter, although the two differ slightly in modern physics?

Different fields of science use the term matter in different, and sometimes incompatible, ways. Some of these ways are based on loose historical meanings, from a time when there was no reason to distinguish mass and matter. As such, there is no single universally agreed scientific meaning of the word "matter". Scientifically, the term "mass" is well-defined, but "matter" is not. Sometimes in the field of physics "matter" is simply equated with particles that exhibit rest mass (i.e., that cannot travel at the speed of light), such as quarks and leptons. However, in both physics and chemistry, matter exhibits both wave-like and particle-like properties, the so-called wave–particle duality.

Questions and answers:
['
Q: What term does science not have a universally-accepted scientific definition for?
A: matter', "
Q: Sometimes scientific terms were historically considered in ways we know now aren't compatible because scientists didn't need to distinguish matter from what other term?
