Physical chemistry : Molecular motion watched.

2013
A laser pulse can switch certain crystals from an insulating phase to a highly conducting phase. The ultrafast molecular motions that drive the transition have been directly observed using electron diffraction.

Inertial and Accelerated Motion in Spacetime Physics

2021
Employing Minkowski’s program for regarding physics as geometry of the real spacetime produces spectacular results – it explained the principle of inertia, the principle of relativity (including the constancy of the speed of light), why acceleration is absolute in both special and general relativity, that absolute acceleration is a manifestation of an ...

Motion Based Physics - Latnex

Latnex v3.0 presents the finalized symbolic framework for a motion-based mathematical system designed to replace traditional time and entropy constructs. Built from directional deviation (Δm), recursive compression (Rᶜ), and collapse activation (Kᵉ), this text-only edition formalizes the core theorems behind the ΣΔm model, the entropy collapse ...

PHYSICAL EXPLANATION OF INERTIA MOTION

Scientific research of the SCO countries: synergy and integration
Newton's first law is accepted as a postulate, i.e. a statement notsupported by evidence and experiments. The statements made in the postulatesmay be erroneous and subsequently recognized as incorrect or inaccurate. Thefundamental task of science is the task of either proving a postulate, or replacingit with another statement confirmed by evidence and ...

Observed Ground Motions, Extreme Ground Motions, and Physical Limits to Ground Motions

2006
This paper examines whether the extremely high ground motion values that are calculated for probabilistic seismic hazard analyses in critical facilities are physically attainable.

Sensitization of Visually Induced Motion Sickness by Prior Provocative Physical Motion

Aerospace Medicine and Human Performance
INTRODUCTION: Habituation to motion has therapeutic applications for motion sickness desensitization and rehabilitation of patients with vestibular disease. Less attention has been devoted to the opposite process: sensitization. METHODS: Subjects (N = 50) were randomly allocated to four sequences: Baseline visual stimulus; then 15 min of time gap ...
