"triple crown" in baseball
In Major League Baseball, a player earns the Triple Crown when he leads a league in three specific statistical categories. For batters, a player must lead the league in home runs, runs batted in (RBI), and batting average; pitchers must lead the league in wins, strikeouts, and earned run average (ERA)
Lou Gehrig Ted Williams

打者の三冠(さんかん)とは,首位打者・最多本塁打・最多打点
三冠を同時に達成した打者を三冠王(さんかんおう・triple crown)とよぶ.英語ではTriple Crownと言う.これら以外の打撃タイトルは,
最多盗塁・最多安打・最高出塁率がある.三冠に最多盗塁をくわえて四冠(よんかん)とする場合もある.
投手の三冠として,最優秀防御率・最多勝利・最多奪三振
とすることがある.さらに,これに最高勝率・最多完封勝利
も合わせて五冠王(ごかんおう)とよぶ場合もある.

treble in football: triple crown in soccer
The term treble or Treble is used in association football to refer to a team winning three trophies in a single season. Honours usually considered to constitute a treble are the top-tier domestic league competition, domestic cup competitions, and continental tournaments. Trophies which consist of a single match or two-leg competition (e.g. the FA Community Shield and UEFA Super Cup) are generally not counted as part of a treble.
International trebles (but not in a single season)France won the 1998 FIFA World Cup, the UEFA Euro 2000, and the 2001 FIFA Confederations CupBrazil won the 2002 FIFA World Cup, the 2004 Copa América, and the 2005 FIFA Confederations Cup

going out of a light bulb
General Electric (GE), founded by Thomas Edison, developed and manufactured light bulbs with tungsten filaments.
Tungsten is less volatile due to its high melting point (3407 deg C) and shows high electric resistivity; a good material for filaments.
"Impurity" in a bulb leads to going out.
QWhy light bulbs with a tungsten filament goes out?What is the impurity?

Langmuir cycle
• Water, impurity, is adsorbed on tungsten surface and leads to formation of tungsten oxide (low melting point) and hydrogen.
• Volatilization of tungsten oxide to be deposited on an inner glass face.• Reaction of tungsten oxide with hydrogen produces water leaving
tungsten on the glass surface.

contribution of Langmuir
research work in GEHe found that adsorption of water should be avoided and that filling up
inert gas, e.g., argon is effective.considered correlations between pressure of gas and amount of
adsorption, leading to "Langmuir isotherm"
Langmuir's theory on adsorption• applicable to almost all adsorptions, especially those occurring in liquid
phase• can be derived theoretically• often combined with kinetic equation for catalytic (photocatalytic)
reactions
-
Advanced Course in Molecular Environmental Science I 37
three assumptions for derivation of Langmuir eq.
• All the adsorption sites are same in quality, i.e., strength of capturing an adsorbate is constant
• Only one adsorbate is adsorbed by one site.
• There is no interaction between sites, i.e., adsorption not influenced by adsorption of neighboring sites

adsorption equilibrium
adsorption equilibrium:same rates of adsorption and desorption
Adsorption rate depends on (1) concentration in bulk and (2) number (density) of vacant sites (V)Desorption rate depends on number (density) of occupied sites (O).
