# gst: a striking analogy between solid–solid and solid–drop frictions

AA << report that the lateral adhesion force between a liquid drop and a solid can also be divided into a static and a kinetic regime. This striking analogy with solid–solid friction is a generic phenomenon that holds for liquids of different polarities and surface tensions on smooth, rough and structured surfaces >>

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 >>
