Balungi Francis

Balungi explains deep ideas in physics in an easy-to-understand way. Think Physics is a series aimed to solving the big problems in physics. The book targets topics that researchers and students spend time wondering about, like the origin of gravity and the universe. It also goes into the theories that seem right but are wrong and shows why they are wrong a rarity in science books. Think Physics series is a rigorously correct, lighthearted, and cleverly...

What exactly is physical reality? In elegant and accessible prose, theoretical physicist Balungi Francis leads us on a wondrous journey from space time singularities to Quantum Black Holes without information loss, from the Bekenstein-Hawking Area entropy law to his famous Volume entropy law of Black holes, from Modified Newtonian Dynamics, Dark Matter to Planck mass particles, from White Dwarfs to Black Holes and from General Relativity to his own...

The universe is full of matter and the attractive force of gravity pulls all matter together.The expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating.Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong...

In Newton's view, all objects exert a force that attracts other objects. That universal law of gravitation worked pretty well for predicting the motion of planets as well as objects on Earth and it's still used, for example, when making the calculations for a rocket launch. But unfortunately it cannot be derived from first principles. While Newton was able to formulate his law of gravity in his monumental work, he was deeply uncomfortable with the...

In Newton's view, all objects exert a force that attracts other objects. That universal law of gravitation worked pretty well for predicting the motion of planets as well as objects on Earth and it's still used, for example, when making the calculations for a rocket launch. But Newton's view of gravity didn't work for some things, like Mercury's peculiar orbit around the sun. The orbits of planets shift over time, and Mercury's orbit shifted faster...
