(Wash your hands!) SUBSCRIBE: Wheeler's delayed choice experiment Wheeler's delayed choice experiment is actually several thought experiments in quantum physics, proposed by John Archibald Wheeler, with the most prominent among them appearing in 1978 and 1984.[1] These experiments are attempts to decide whether light somehow "senses" the experimental apparatus in the double-slit experiment it will travel through and adjusts its behavior to fit by assuming the appropriate determinate state for it, or whether light remains in an indeterminate state, neither wave nor particle, and responds to the "questions" asked of it by responding in either a wave-consistent manner or a particle-consistent manner depending on the experimental arrangements that ask these "questions."[2]
Uncovering Da Vinci's Rule of the Trees As trees shed their foliage this fall, they reveal a mysterious, nearly universal growth pattern first observed by Leonardo da Vinci 500 years ago: a simple yet startling relationship that always holds between the size of a tree's trunk and sizes of its branches. A new paper has reignited the debate over why trees grow this way, asserting that they may be protecting themselves from wind damage. "Leonardo's rule is an amazing thing," said Kate McCulloh of Oregon State University, a scientist specializing in plant physiology.

PDQ Blog An inside look at some of the top teacher prep programs Today NCTQ released its Teacher Prep Review, which takes a close look at the quality of training provided by 2,420 teacher preparation programs across the country. Our results show that most have a long way to go to get teachers classroom ready from day one. But there are some programs that stand out. To paint a picture of what strong teacher prep can look like, we've created short videos on some of the programs that excel overall (Lipscomb University, Ohio State) or in particular areas (Louisiana State in elementary math, Arizona State in student teaching, and Morgan State in elementary and secondary content). It's programs like these that aspiring teachers should strongly think about applying to and that districts should look to recruit from.

Bifurcation diagram In mathematics, particularly in dynamical systems, a bifurcation diagram shows the possible long-term values (equilibria/fixed points or periodic orbits) of a system as a function of a bifurcation parameter in the system. It is usual to represent stable solutions with a solid line and unstable solutions with a dotted line. Bifurcations in 1D discrete dynamical systems[edit] Logistic map[edit] Animation showing the formation of bifurcation diagram An example is the bifurcation diagram of the logistic map:

Je m'y replongerai. p.s. : si vous aviez quelques pistes de la même veine en français...je serais preneur. by reel Aug 22
