The Schr\"odinger-Newton equations beyond Newton [PDF]
The scope of this paper is twofold. First, we derive rigorously a low-velocity and Galilei-covariant limit of the gravitoelectromagnetic (GEM) equations.

The Radius of PSR J0740+6620 from NICER and XMM-Newton Data [PDF]
PSR J0740+6620 has a gravitational mass of 2.08 ± 0.07 M ⊙, which is the highest reliably determined mass of any neutron star. As a result, a measurement of its radius will provide unique insight into the properties of neutron star core matter at high ...

A NICER View of the Massive Pulsar PSR J0740+6620 Informed by Radio Timing and XMM-Newton Spectroscopy [PDF]
We report on Bayesian estimation of the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J0740+6620, conditional on pulse-profile modeling of Neutron Star Interior Composition Explorer X-ray Timing Instrument event data.

Can we know what Newton's scientific method is? [PDF]
I have tried to retrieve Newton’s scientific method. To do so, I raise two principal questions: 1. What is Newton’s evolving scientific method that he devised in The Principia and Opticks during a period of fifty years? 2.

INVESTIGATION ON TRADE OF ÇORUM WITH SURROUNDING PROVINCES BY GRAVITY MODEL
In this study, the trade relationship of Çorum province with the surrounding provinces was examined by using Newton's Gravity Model. Newton's Gravity Model is used to model the gravitational forces of planets and their physical states in space.

The Experimental Philosophy or Francis Bacon’s Elenchus [PDF]
Critical rationalism faces difficulty in Karl Popper’s Socratic formulation: “I may be wrong, and you may be right, and by an effort, we may find the truth.” But the Socratic elenchus, using refutations, can only give us negative knowledge of general ...
