NYU researchers created a new type of time crystal suspended in mid-air Sound waves move floating beads in rhythmic patterns, defying basic physics. The experiment reveals motion and energy transfer ...

Abstract: Give a finite undirected graph G = (V, E) and a positive integer κ ≥ 1, a distance-k matching is an edge set D ⊂ E that the pairwise distance of edges in D is at least k in G. The famous ...

The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Time feels like the most basic feature of reality. Seconds tick, days pass ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Learn how to analyze motion graphs in physics, including position-time and velocity-time graphs. This video explains slopes, areas, and motion behavior to help you clearly interpret real physics ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

No matter how many times I’ve been told (or written about) the importance of a slow run, I cannot translate it into my training. This is not to say I am the fastest runner. My half marathon goal time ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

Abstract: Permutation entropy (PE) is a widely used metric for quantifying the complexity of time series data. Recent efforts have extended PE to graph signals, resulting in the graph permutation ...

STG-DMD (Sparse-Coded Time-Delay Graph Dynamic Mode Decomposition) is a data-driven framework for modeling nonlinear dynamics on graph structures. It integrates: StgDmd/ ├── code/ │ ├── artificial/ │ ...
