Physics can feel inscrutable to students; this lesson helps them understand a graphing problem by analyzing their own ...

This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

A century ago, a star in Andromeda named V1 launched a revolution in astronomy, revealing its true immensity and the origin ...

Real life situations such as travelling over time and across distance can be drawn on a graph. Exact distances and times are plotted on the graph. These are shown as co-ordinates. These points are ...

A tool called AI-Newton can derive scientific laws from raw data, but is some way from developing human-like reasoning.

A dangerous Russian tactic exposed: What Ukrainian combat footage revealed Ultra-secretive billionaire who gave US military $130million lifeline is unmasked BI asks Cagayan de Oro court to return Tony ...

Researchers have combined the Dijkstra and Bellman-Ford algorithms to develop an even faster way to find the shortest paths ...

Scientists struggle with the physics of fluids. A recent Google breakthrough could support better predictions and practical ...

When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...

Hanging by a thread: Wasp spiders, Argiope bruennichi, are known to incorporate so-called “stabilimenta” into their web structure, but the function of these “extra touches” has remained unknown.

Abstract: This article addresses the velocity-free attitude control problem for rigid spacecraft with bounded external disturbances. To obtain an accurate estimate of the spacecraft's velocities and ...
