Grantmakers for Education, 2020 In March 2020, the nation's schools began shutting down in an effort to slow the spread of COVID-19. More than 55 million students as well as teachers, administrators and families have had to adapt at lightning speed. Philanthropists have responded quickly, but the need for educating students has garnered little funding attention so far.

Approximation BKW En physique, l'approximation BKW (en l'honneur de Léon Brillouin[1], Hendrik Anthony Kramers[2] et Gregor Wentzel[3]) est une méthode développée en 1926 qui permet d'étudier le régime semi-classique d'un système quantique. La fonction d'onde est développée asymptotiquement au premier ordre de la puissance du quantum d'action L'idée de base de la méthode BKW est que l'équation de Schrödinger se dérive de l'équation de propagation des ondes. On doit donc retrouver la mécanique classique dans la limite comme on retrouve l'optique géométrique lorsque la longueur d'onde dans la théorie de l'optique ondulatoire. L'approximation BKW (pour les francophones européens) est également connue sous les initiales WKB (pour les anglophones et les francophones nord-américains), WKBJ, BWKJ et parfois WBK ou BWK. Formule à une dimension d'espace[modifier | modifier le code] De façon générale, la fonction d'onde est mise sous la forme ansatz : est utilisé, c'est ce cas que nous allons développer ici.

□ LHCb: le modèle standard n'a qu'à bien se tenir ! En mars dernier, la collaboration LHCb (auprès du LHC, CERN) a présenté pas moins de quatre résultats majeurs d'une précision inédite aux Rencontres de Moriond et de la Thuile, chacun d'entre eux ouvrant la voie vers de nombreuses pistes pour déstabiliser le modèle standard de la physique des particules (La physique des particules est la branche de la physique qui étudie les constituants...). Au programme de ce tour d'horizon (Conceptuellement, l’horizon est la limite de ce que l'on peut observer, du fait de sa propre...): une particule neutre aux propriétés étonnantes, quatre nouveaux tétraquarks et un résultat intriguant et prometteur impliquant le muon (Le muon est, selon le modèle standard de physique des particules, le nom donné à...).
