Understanding Gravitational Waves
The birth of a completely new branch of observational astronomy is a rare and exciting occurrence.For a long time, our theories about gravitational waves—proposed by Albert Einstein and others more than a hundred years ago—could never be fully proven, since we lacked the proper technology to do it. That all changed when, on September 14, 2015, instruments at the LIGO Observatory detected gravitational waves for the first time. This book explores the nature of gravitational waves—what they are, where they come from, why they are so significant and why nobody could prove they existed before now.Written in plain language and interspersed with additional explanatory tutorials, it will appeal to lay readers, science enthusiasts, physical science students, amateur astronomers and to professional scientists and astronomers.

Portfolio Management : Delivering on Strategy
Portfolio management is becoming the ‘must have’ for organizations to prosper and survive in this decade and beyond.No longer can the organizational focus be one of following best and repeatable practices as resource limitations mean only those programs, projects, and operational work that add business value can and should be pursued.Executives are focusing on strategic ability and managing complexity, which can only be done through a disciplined portfolio process in ensuring the best mix of programs, projects, and operational work is under way.In turn, the portfolio is constantly in flux as difficult decisions are made if a project, for example, is no longer contributing to business value and providing benefits and should be terminated to reallocate resources to one of higher priority.Commitment to this difficult approach is necessary at all levels, and communication is required so everyone knows how their work contributes to the organization’s strategic goals and objectives. Portfolio Management: Delivering on Strategy, Second Edition focuses on the benefits of portfolio management to the organization.Its goal is to provide senior executives a view on how portfolio management can deliver organizational strategy.The emphasis is on the specific aspects within the portfolio management discipline and how each aspect should be managed from a business perspective and not necessarily from a portfolio management perspective.Highlights of the book include:Agile portfolio management Delivering organizational value Portfolio management and uncertainty Portfolio governance Marketing a portfolio Portfolio management success Starting with a review of the project portfolio concept and its development, this book is a reference for executives and practitioners in the field, as well as a students and researchers studying portfolio management.

Gravitational Wave Astrophysics (IAU S338) : Early Results from Gravitational Wave Searches and Electromagnetic Counterparts
Gravitational waves were predicted 100 years ago by Einstein as part of his general theory of relativity.This volume contains the exciting results presented at IAU Symposium 338, following the announcement of the first results of the observation of the collision of neutron stars by the LIGO and Virgo Advanced detectors, and follow-up observations by many ground-based and space telescopes.These observations provided an incredible context for the talks, posters and discussions at the meeting, fostering new interactions and collaborations between physicists and astronomers in an exciting new era of multimessenger astrophysics.For the first time, space-time messengers (gravitational waves) and electromagnetic ones (visible, infrared and ultraviolet light, x-rays, gamma-rays, radio waves) can be correlated, to increase our understanding of binary systems of compact objects, rotating or exploding stars and other astrophysical phenomena.A new window has opened through which we can view the cosmos.

What is gravitational pseudoforce?
Gravitational pseudoforce, also known as the centrifugal force, is a fictitious force that appears to act on objects in a rotating frame of reference. It is not a true force like gravity, but rather an apparent force that arises due to the acceleration of the reference frame. This pseudoforce is experienced by objects in a rotating system and is directed away from the axis of rotation. It is important to account for gravitational pseudoforce when analyzing the motion of objects in a rotating reference frame.

What is gravitational circulation?
Gravitational circulation is the movement of fluids caused by differences in density due to gravity. In this process, denser fluid sinks while less dense fluid rises, creating a continuous circulation pattern. This phenomenon is commonly observed in oceans and lakes, where differences in temperature and salinity lead to variations in water density and drive the circulation of water masses. Gravitational circulation plays a crucial role in redistributing heat and nutrients in aquatic environments, influencing the overall ecosystem dynamics.
-
What is gravitational redshift?
Gravitational redshift is a phenomenon in which light or other electromagnetic radiation is shifted to longer wavelengths (lower frequencies) as it travels away from a gravitational field. This occurs because the gravitational field causes time to dilate, which in turn affects the frequency of the light. As the light moves away from the gravitational field, it loses energy and its wavelength increases, resulting in a redshift. Gravitational redshift is a key prediction of Einstein's general theory of relativity and has been observed in various astronomical contexts, providing evidence for the theory's validity.

What are gravitational forces?
Gravitational forces are the attractive forces between two objects with mass. These forces are responsible for the phenomenon of gravity, which is the force that pulls objects towards each other. Gravitational forces are described by Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravitational forces are fundamental to the behavior of celestial bodies in space and are also important in understanding the motion of objects on Earth.

Where are gravitational lenses applied?
Gravitational lenses are applied in the field of astronomy and astrophysics to study distant galaxies, stars, and other celestial objects. They are used to magnify and distort the light from these objects, allowing scientists to observe and study them in greater detail. Gravitational lenses are also used to test and validate the theory of general relativity, as they provide evidence of the bending of light by massive objects such as galaxies and galaxy clusters. Additionally, gravitational lenses have the potential to be used in future space missions for magnifying and studying exoplanets and other objects in distant solar systems.
-
Is the gravitational force constant?
No, the gravitational force is not constant. It varies depending on the masses of the objects involved and the distance between them. According to Newton's law of universal gravitation, the force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them. This means that as the masses or distance change, the gravitational force will also change.
-
Do gravitational waves bend time?
Yes, gravitational waves do bend time. According to Einstein's theory of general relativity, gravity is not just a force that acts on objects, but it also warps the fabric of spacetime. When massive objects accelerate or move, they create ripples in spacetime known as gravitational waves. These waves cause the fabric of spacetime to stretch and compress, which in turn affects the flow of time. This phenomenon has been observed and confirmed by the detection of gravitational waves from merging black holes and neutron stars.

What is a gravitational field?
A gravitational field is a region in space around a massive object where another object with mass experiences a force due to gravity. The strength of the gravitational field is determined by the mass of the object creating the field. In this field, any object with mass will experience a force of attraction towards the massive object. The gravitational field is a fundamental concept in physics and is used to explain the behavior of objects in the presence of gravity.
