Celebrating the Physics in Geophysics [PDF]
Eos, Transactions American Geophysical Union, 2005 As 2005, the International Year of Physics, comes to an end, two physicists working primarily in geophysical research reflect on how geophysics is not an applied physics.

Geodesy, Geophysics and Fundamental Physics Investigations of the BepiColombo Mission [PDF]
Space Science Reviews, 2021 AbstractIn preparation for the ESA/JAXA BepiColombo mission to Mercury, thematic working groups had been established for coordinating the activities within the BepiColombo Science Working Team in specific fields. Here we describe the scientific goals of the Geodesy and Geophysics Working Group (GGWG) that aims at addressing fundamental questions ...

Physical‐statistical modeling in geophysics [PDF]
Journal of Geophysical Research: Atmospheres, 2003 Two powerful formulas have been available to scientists for more than two centuries: Newton's second law, providing a foundation for classical physics, and Bayes's theorem, prescribing probabilistic learning about unknown quantities based on observations.

The physics of premelted ice and its geophysical consequences [PDF]
Reviews of Modern Physics, 2006 The surface of ice exhibits the swath of phase-transition phenomena common to all materials and as such it acts as an ideal test bed of both theory and experiment. It is readily available, transparent, optically birefringent, and probing it in the laboratory does not require cryogenics or ultrahigh vacuum apparatus.

Pressure-induced inverse order-disorder transition in double perovskites
, 2020 Given the consensus that pressure improves cation order in most of known materials, a discovery of pressure-induced disorder could require reconsideration of order-disorder transition in solid state physics/chemistry and geophysics.

Overview of Physics-Informed Machine Learning Inversion of Geophysical Data
CoRR, 2023 We review four types of algorithms for physics-informed machine learning (PIML) inversion of geophysical data. The unifying equation is given by the joint objective function $ε$: \begin{eqnarray} ε^{||-PIML}&=&λ_1 \overbrace{||{\bf W}^{ML}({\bf H}_{\bf w} {\bf d}^{obs}-{\bf m})||^2}^{NN} + λ_2 \overbrace{{||{\bf W}^{FWI}({\bf L} {\bf m}-{\bf d}^

Radiogenic power and geoneutrino luminosity of the Earth and other terrestrial bodies through time
, 2020 We report the Earth's rate of radiogenic heat production and (anti)neutrino luminosity from geologically relevant short-lived radionuclides (SLR) and long-lived radionuclides (LLR) using decay constants from the geological community, updated nuclear ...
