# soc: four plausible scenarios: if this is the scorecard after (#1, #2), what will (#3) democracy look like after (#4) years of (#5), by Brian

<< If this is the scorecard after 10 months (#1, #2), what will American (#3) democracy look like after four (#4) years of Trump(#5)? Will it be recognizable? As I see it, there are four plausible scenarios, ranging from the hopeful to the catastrophic >> Brian Klaas

<<
1. The Trump Vaccine [..]
2. Democratic Decay [..]
3. The Forerunner [..]
4. American Authoritarianism [..]

ipoteticamente i 4 scenari ("four plausible scenarios") indicati da Brian Klaas potrebbero essere riconducibili e anche individuabili attraverso ipotetiche  'traiettorie' generate da  componenti strutturali che gia' sono presenti, attivi e coesistono 'in nuce',  sottotraccia, in quel tessuto sociale (e altrove); di volta in volta, in funzione delle caratteristiche del sistema al tempo 't' (e anche per componenti  casuali, fluttuanti, oppure per autoamplificazione di una singolarita' che interferisca  all'interno e all'intorno), un 'ramo' della dinamica emerge, si stabilizza e predomina transitoriamente sulle altre tre in una specie di danza tra stati stazionari (di meta-stabilita') e oscillaz periodiche e aperiodiche; in prima approx la soluzione (1.) potrebbe dipendere dalla velocita' e dalla efficacia  dell'immunizzazione individuale; la (2.) dalle specifiche caratteristiche del tessuto economico sociale culturale al tempo 't'; la (3.) dalla esistenza nel contesto di 'adatta entita'' immediatamente operativa (l'adatto attrattore disponibile); la (4.) dal complesso intrecciato di problematiche assai male/mai risolte e/o assai male/mai impostate dalle classi dirigenti che hanno preceduto l'ineffabile Donald;

# chem: Van der Waals' bonds: to measure the tensile strength and the force required to pull the crystal until it breaks

<< Van der Waals' are weak electric forces that attract atoms to one another through subtle shifts in the atom's electron configurations >>

AA << grew and compared three different types of crystals: one pure gallium selenide, one with 0.6 percent tellurium and one with 10.6 percent tellurium. To test the effect on the tellurium on interlayer bonding, [AA] invented the equivalent of a crystal sandwich opener. Their system is able to measure with exquisite detail the tensile strength, the force required to pull the crystal until it breaks >>

# game: Kel'Thuzad e' il Lich responsabile

<< Kel'Thuzad e' il Lich responsabile di aver diffuso la piaga dei non-morti nel regno di Lordaeron ma e' probabilmente piu' conosciuto dai fan per essere il signore della necropoli di Naxxramas e dunque il boss finale dell'omonimo dungeon. Apparsa inizialmente in World of Warcraft, Naxxramas fu poi riutilizzata nella seconda espansione, Wrath of the Lich King, poiche' quasi nessuno era riuscito a raggiungere il livello necessario per provare il raid la prima volta >>
