The lanthanide contraction is the greater-than-expected decrease in atomic radii/ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected atomic radii/ionic radii for the subsequent elements starting with 72, hafnium. The term was coined by the Norwegian geochemist Victor Goldschmidt in his series "Geochemische Verteilungsgesetze der Elemente" (Geochemical distribution laws of the elements). (Wikipedia).

The Mechanism of Muscle Contraction: Sarcomeres, Action Potential, and the Neuromuscular Junction
We've learned about the types of muscle, including skeletal muscle, and we know then when these muscles contract, we are able to move our bodies around. But how exactly does this happen on the molecular level? There is an astonishing amount of chemistry happening to make this work, so let'

Thermal Stress and Strain - Basic Introduction - Compressive & Tensile Forces, Elastic Modulus
This physics video tutorial provides a basic introduction into thermal stress and strain. As the temperature increases, the length of the rod increases; therefore, a compressive force is exerted by the two vertical supports to keep the rod at constant length - the material is under compre
