Flights of Fancy talks about almost every aspect of flying–all the different ways of defying gravity–in imagination and in technology, in humans and in animals. It ranges over many instances of flight including the Wright brothers, Greek mythology, extinct and living birds, helicopters, insects, bats, and flying squirrels.
The gain in efficiency is explained by the Oberth effect, wherein the use of a reaction engine at higher speeds generates a greater change in mechanical energy than its use at lower speeds. In practical terms, this means that the most energy-efficient method for a spacecraft to burn its fuel is at the lowest possible orbital periapsis , when ...
In doing so, we can break through the gravitational forces that limit us and create the space for more women to lead, thrive, and transform industries. Read more:
In cosmology, the anthropic principle, also known as the observation selection effect, is the proposition that the range of possible observations that could be made about the universe is limited by the fact that observations are only possible in the type of universe that is capable of developing observers in the first place.
Before Newton's law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

In order to map a body's gravitational influence, it is useful to think about what physicists call probe or test particles: particles that are influenced by gravity, but are so small and light that we can neglect their own gravitational effect. In the absence of gravity and other external forces, a test particle moves along a straight line at a ...
