More about hadron
Hadron 鈥渁n elementary particle subject to the strong nuclear force鈥� is a coinage based on Ancient Greek 丑补诲谤贸蝉 鈥渢hick, bulky鈥� or 鈥渟trong, great,鈥� with the suffix -on (clipped from ion). Hadron is not related to the name Hadrian, which comes from a Roman place name that is also the source of Adriatic. Some linguists connect 丑补诲谤贸蝉 to Old English 蝉忙诲 鈥渟ated, full鈥� or 鈥渉eavy, weary鈥� (compare modern English sad) on the grounds that Ancient Greek h tends to correspond to English s. If this connection is valid, that also makes 丑补诲谤贸蝉 a relative of Latin satis 鈥渆nough鈥� (found in asset, satiate, and satisfy) and satur 鈥渇ull, well-fed鈥� (found in satire and saturate). Russian physicist Lev Okun created hadron in 1962 as a counterpart of lepton (from Ancient Greek 濒别辫迟贸蝉 鈥渟mall, slight鈥�).

Protons are the only hadrons known to be stable in isolation鈥攏eutrons are stable only when they are incorporated into atomic nuclei. All other hadrons form only fleetingly, from the collision of other particles, and decay in a fraction of a second. So the LHC [Large Hadron Collider] creates new kinds of hadron by causing high-energy, head-on collisions between protons.
Quarks are elementary particles that usually combine in groups of twos and threes to form hadrons such as the protons and neutrons that make up atomic nuclei. More rarely, however, they can also combine into four-quark and five-quark particles, or tetraquarks and pentaquarks.
majesty
noun
regal, lofty, or stately dignity; imposing character; grandeur.
More about majesty
Majesty, “regal, lofty, or stately dignity,” comes from Middle English majeste, which ultimately comes from the Latin stem 尘补箩别蝉迟腻蝉,聽meaning “dignity, grandeur.”聽Majesty was used first in the Christian Church in reference to a deity, then as a title of address or of dignity for kings and queens, and then in Roman history in reference to the power and dignity of the Roman people. It also appears in past 51吃瓜 of the Day聽lese majesty, which can be defined as an attack on any custom, institution, or belief held sacred or revered by numbers of people. Majesty entered English between聽1250鈥�1300.

The Catskills are the mountains for all seasons. Some, 300,000,000 years have not dimmed the splendor and majesty of this family of almost seventy mountains and the 1,000 square miles of territory they embrace.
There is a majesty and history to this pre-war building that only our incredible orchestra is truly able to evoke. But then there are quirkier, darker elements with my voice, autoharps, affected pianos that bring a modernness to it all as well.
More about scholarch
Scholarch 鈥渢he head of a school鈥� comes from Ancient Greek 蝉肠丑辞濒谩谤肠丑脓蝉, of the same general meaning, which is a compound of 蝉肠丑辞濒岣� 鈥渓eisure employed in learning鈥� and -补谤肠丑脓蝉, a combining form of 谩谤肠丑辞蝉 鈥渓别补诲别谤.鈥� 厂肠丑辞濒岣�, of course, is the source of scholar, scholastic, and school. The trigraph sch has two predictable pronunciations in English: sch is pronounced as 鈥渟huh鈥� in words of German origin (such as the recent 51吃瓜s of the Day schwa and Weltanschauung) and as 鈥渟kuh鈥� in words of Ancient Greek or Italian origin (such as the recent 51吃瓜s of the Day paschal and scherzando). Scholarch was first recorded in English in the early 1860s.
how is scholarch used?
We do know that after having served as Lector in the Academy and being described as its 鈥淢ind鈥� by Plato, Aristotle was not chosen as the latter鈥檚 successor. The job of scholarch, or head of the school, went to Speusippus, Plato鈥檚 nephew. Aristotle left Athens shortly after Plato鈥檚 death and stayed away for around 12 years.
The scholarch had been instituted in the Strassburg gymnasium in 1528 as well as in the schools of Bern and Basel to assist the rector in his administrative tasks, particularly in the allocation of public funds, and to serve as the government鈥檚 representative to the school.
