METHODS. N/N1003A rabbit lens epithelial cells were used in the experiments. PKC translocation or in vivo Cx43 phosphorylation on serine was determined by Western blot analysis. Gap junction activity was measured by scrape-loading/dye-transfer assay. The number of cell surface gap junction ...
Newton'sthird lawis often stated as "for every action there is an equal and opposite reaction," but a more precise formulation would be: if an object exerts a force on a second object, the second object exerts a force of equal magnitude and opposite direction on the first object. In oth...
1. There is more stuff (matter) that we don't see with our telescopes. We call this dark matter. 2. Newton's laws and even GR are wrong on the scale of galaxies and everything bigger. This idea is usually called modified gravity (because we need to modify GR) or Modified Newtonian...

unbalanced force.” The second law states that acceleration is produced when a force acts on a mass – ergo, the greater the mass of the object, the greater the force required to accelerate it. The third and final law states that “for every action, there is an equal but opposite ...
your center of mass is pulling back at the Earth. But the more massive body barely feels the tug from you, while with your much smaller mass, you find yourself firmly rooted thanks to that same force. Yet Newton's laws assume that gravity is an innate force of an object that can act...
Physics majors usually start with an introductory course that covers topics such as Newton’s laws of motion, kinematics and rotational motion. Studying physics requires a strong background in mathematics, and students should expect to complete coursework in calculus and differential equations, for inst...
Although born in South Africa, Bessie Head spent much of her life in Botswana, and is widely considered one of the country’s most influential writers. First published in 1971, Maru tells the story of an orphan who goes to teach in a remote village in Botswana and how her presence polariz...
