Despite Trump's rhetorical nods to the social conservative wing of his party during the campaign and his enthusiasm for convenient conspiracy theories, he is clearly a pragmatist with little worry about changing his policy preferences.
The range of Reynolds number in insect flight is about 10 to 104, which lies in between the two limits that are convenient for theories: inviscid steady flows around an airfoil and Stokes flow experienced by a swimming bacterium.
It has shades of the convenient "lone wolf" theory about it.
This may be due to an inherent flaw in the convenient sentinel node theory.
This simple theory is convenient for purposes of exposition, even though solid-state physics has advanced beyond it.
Some private-label A.T.M.'s, like those in gas stations or convenient stores, might, in theory, be subject to similar, if less high-tech, "denial of service" attacks because they sometimes use telephone lines to reach their networks.
M-band MWPTs may offer great potential for image processing, but substantial extension of both their fundamental theory and convenient methodology are required.
In order to see most clearly that Newtonian mechanics should be expected to emerge from Bohmian mechanics in the classical limit, it is convenient to transform the theory into Bohm's Hamilton-Jacobi form.
So it could be convenient, before teaching Darwinian theory, to emphasize change and to provide some evidence of it, in order to make it acceptable that all living beings evolved in the past and are evolving in the present.
