We analyze the natural process of flipping a coin which is caught in the hand. We show that
vigorously flipped coins tend to come up the same way they started. The limiting chance of …

The dynamics of the tossed coin can be described by deterministic equations of motion, but
on the other hand it is commonly taken for granted that the toss of a coin is random. A …

The analysis of wind-influenced projectile motion in the case of linear and nonlinear
(quadratic or nonquadratic) drag force is reviewed. For quadratic or more general nonlinear …

In this article, we revisit projectile motion assuming a retarding force proportional to the
velocity, $\vec {{F} _ {r}}=-{mk}\vec {V} $. We obtain an analytical expression for the set of …

Diving beetle, an excellent biological prototype for bionic underwater vehicles, can achieve
forward swimming, backward swimming, and flexible cornering by swinging its two powerful …

The paradigm of bare-hand interaction has become increasingly prevalent in Augmented
Reality (AR) and Virtual Reality (VR) environments, propelled by advancements in hand …

The drop tower is an important experimental facility to provide a microgravity environment on
the ground. The National Precise Gravity Measurement Facility has built a vacuum drop …

As marine vessels are becoming increasingly automated, having accurate simulation
models available is turning into an absolute necessity. This holds both for the facilitation of …

A probing examination of the dynamic history of predictive methods and values in science
and engineering that helps us better understand today's cultures of prediction. The ability to …

On September 18, 1915, Jules Haag (Figure1), a young professor of rational mechanics
from the University of Clermont-Ferrand, wrote to his old mentor, Professor Paul Appell, in …
