ABSTRACT We present the results of a search for cool subdwarfs for which our candidates were drawn from a V−J reduced proper‐motion diagram constructed by Salim & Gould. Kinematic (U, V, and W) and ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

THIS little work, in spite of its ponderous and somewhat ambiguous title, is a useful and workmanlike collection of curves from which may be obtained the value of the mean velocity v in the empirical ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

Students in any classroom around the world could soon be able to reimagine the standard diagrams in any physics textbook by ...

Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. “Proteins are the molecular machines that power all life on ...

Two forces can be added together to find a resultant force. In the diagram of a toy trailer below, when two children pull on the handle, one with a force of 3 newtons (N) to the left and one with a ...

Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don't seem to work together. Physical phenomena rely on ...
