Midair Haptic Pursuit

Midair collisions enhance saltation.

Here we address the old question in aeolian particle transport about the role of midair collisions. We find that, surprisingly, these collisions do enhance the overall flux substantially. The effect depends strongly on restitution coefficient and wind speed. We can explain this observation as a consequence of a soft bed of grains which floats above the ground and reflects the highest flying par...

TCAS: A System for Preventing Midair Collisions

To reduce the possibility of midair collisions, the Federal Aviation Administration has developed the Traffic Alert and Collision Avoidance System, or TCAS. This airborne system senses the presence of nearby aircraft by interrogating the transponders carried by these aircraft. When TCAS senses that a nearby aircraft is a possible collision threat, TCAS issues a traffic advisory to the pilot, in...

Tenability Pursuit

Recently Hájek prophesied that “as fans of the Friday the 13th series know, you should never be surprised if Jason suddenly reappears in a new guise – and the same is true for Stalnaker’s Thesis” (Hájek, 2011, p. 14). So what better day to pick for a plea for the thesis than today? Obviously, a new guise is also needed for the thesis; it cannot live on in the way as it is understood in the triv...
