Earth's seasons are a result of the planet's orbit and axial tilt. John Lamb / Getty Images It turns out that the elliptical orbit of the Earth has little effect on the seasons. Instead, it is the 23.45-degree tilt of the planet's rotational axis that causes us to have winter and...

Though such asymmetries were already measured for the first time about four decades ago, their origin is still under debate. Here we consider transverse single-spin asymmetries in semi-inclusive lepton-nucleon scattering, in nucleon-nucleon scattering, and in inclusive lepton-nucleon scattering. It ...

Causes of dizziness are numerous, and it could be difficult to list them all. It’s also important to describe dizziness. Some people use the term to mean faintness, while others mean loss of balance, trouble concentrating, feeling lightheaded, feeling nauseous, or having the “roomspinning”...

Another practical application of centripetal force is the laboratory centrifuge, which is used to accelerate liquid suspensions. Centrifuges are key toolsused in blood sample analysis. Normally, thermal motion causes continuous mixing, which prevents gravity from forcing blood cells to settle out into ...
While the laws of gravity work just fine to model what we need in sufficient detail, there is still confusion of what causes the observed phenomenon of attraction between masses. We have the proponents of “pushing gravity” who say it’s the fluid aether pushing things together. Then there ...
