The dust motes are travelling in parallel paths, but perspective makes them seem to spread out from a point in Perseus (see chart).
Opened by William Becknell, a trader, the trail was used by merchant wagon caravans travelling in parallel columns, which, when Indians attacked, as they did frequently between 1864 and 1869, could quickly form a circular line of defense.
We thus generated two abrupt fronts, one oxidizing and the other reducing, which subsequently travelled in parallel by advection through the sand body.
In a hierarchical network, information can flow in both directions, can skip intermediate levels, and can travel in parallel through distinct channels (Felleman and Van Essen 1991).
Moreover, if the droplets are simply carried along so that their velocity always equals that of the air, then as two drops draw closer they should travel essentially in parallel at the same speed and take a long time to merge.
May be realised millenia or millions of years in the future: faster-than-light travel, time travel, parallel universes Type 3 impossibilties Technologies that violate the known laws of physics.
Depending upon definition of the curvature tensor, this may lead to conditions for travel in a parallel universe, faster than light travel and past/future time travel.
The trick is to use DNA-based landmarks that physically travel through generations in parallel with the trait of interest.
(A, B) Relatively thick cortical bone; the cancellous bone travels in a direction parallel to the longitudinal axis of the tooth, and the density is low.
