In his seminal work, Conrad Waddington employed deterministic differential equations to define epigenetics as the emergence of a phenotype that can be perturbed by the environment but whose endpoints ...

DIY Science Time is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, and ...

Any object lifted above the ground has gravitational potential energy (\(E_{p}\) or GPE). The amount of gravitational potential energy an object has on Earth depends on its: mass; height above the ...

The interatomic potential describes the interaction between a pair of atoms or the interaction of an atom with a group of atoms in a condensed phase. The potential must have both an attractive and a ...

Roller coasters rely on two types of energy to operate: gravitational potential energy and kinetic energy. Gravitational potential energy is the energy an object has stored because of its mass and its ...

If an object is lifted, work is done against the force of gravity. When work is done energy is transferred to the object and it gains gravitational potential energy. If the object falls from that ...

It should be clear that our world runs on energy. Driving your car, washing your clothes, heating your house, and even running your computer (so you can read this post)—these things all require energy ...
