Simulations allow students to visualize processes like genetic drift that occur over timescales scales that are difficult or impossible to observe directly, and also allow students to isolate and manipulate parameters that influence the outcome of the simulation, in order to better understand the many variables and their interactions (National Research Council 2011).
It is impossible to observe wave and particle properties simultaneously.
It is impossible to observe both the wave and particle aspects simultaneously.
But if the tempo is too fast to begin with, he demonstrated, it is impossible to observe the accelerando marking and whip up real excitement near the end of the movement.
It has long been considered technically impossible to observe the radiotracer-treated culture and the roots directly and simultaneously, because traditional imaging methods do not have a sufficiently broad range of detection that can accept such contrast.
Unlike the plutonium route to the bomb, which was limited to creating no more than one bomb's worth of plutonium in a reactor annually and was highly observable, the uranium route was potentially unbounded and impossible to observe from afar.
Moreover, this heterogeneity is demonstrably impossible to observe using only mean-aggregated data and serves to further emphasize the contributions our observatory and approach can make to theory.
Thus, for visible light at the shortest possible wavelength of 400 nanometres (nm), features smaller than 200 nm would be blurred out, and many features of cells and microorganisms would be impossible to observe.
The analysis of the model dynamics on the proposed time scales has allowed for the observation of some theoretical findings known from the behavioral economics [34 38], and which are impossible to observe when analyzing the model dynamics on the traditional homogeneous time scales (that is, with (muequiv mathrm{const.})).}
Context is everything, of course, and it's impossible to observe Guantánamo's recent history in a vacuum from its longer one.
