In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent,...

Earth's Atmospheric Oxygen Levels Continue Long Slide
Atmospheric oxygen levels have declined over the past 1 million years, although not nearly enough to trigger any major problems for life on Earth, a new study finds.
Scientists Just Say No To ‘Chemtrails’ Conspiracy Theory
One persistent belief in some quarters is that the government — or business, perhaps — is deploying a fleet of jet aircraft to spray chemicals into the sky to control the population, food supply or ot...
The 2016 Atlantic Hurricane Season Might Be The Strongest In Years
NOAA is out with a new forecast for the 2016 Atlantic hurricane season
There's A Mysterious Sound Coming From The Caribbean That's So Loud It Can Be Heard From Space
The "Rossby whistle" is many octaves below the range of human hearing. In what sounds like a plot device from a science fiction movie involving sea monsters and aliens, a strange sound is coming out o...
Best Fat Burner
You may have come across a ton of lists that claim to include fat-burning foods. Did you know that best fat burner has been there around you all this while?
Dust From Sahara Makes Significant Impact On Caribbean Sea Ecosystem, Research Shows
Atmospherically transported dust from the Sahara Desert, the largest desert in the world, is bringing iron and other nutrients to underwater plants in the Caribbean, but bacteria may be the first thin...
New state of water molecule discovered at Oak Ridge National Laboratory
Scientists at the Department of Energy's Oak Ridge National Laboratory have observed water molecules behaving unlike gas, liquid or solid states.
Water has Memory
Many researchers are convinced that water is capable of "memory" by storing information and retrieving it.
Melting A Sock With Sulfuric Acid
Melting a sock with sulfuric acid! This video demonstrates how sulfuric acid reacts with your clothing. Within a matter of three minutes the sock was melted down to an awesome glob of goo.
Can You Walk on Water? (Non-Newtonian Fluid Pool)
Running, jumping and biking on 8,000 litres of non-newtonian fluid in Kuala Lumpur, Malaysia!
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states ...
Liquid - Wikipedia
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental mo...

Plasma (physics)
Plasma (from Greek πλάσμα, "anything formed") is one of the four fundamental states of matter, the others being solid, liquid, and gas. A plasma has properties unlike those of the other states.A plasm...

Fluid mechanics
Fluid mechanics is the branch of physics which involves the study of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics can be divided into fluid statics, the study of fluid...
Rheology (/riːˈɒlədʒi/; from Greek ῥέω rhéō, "flow" and -λoγία, -logia, "study of") is the study of the flow of matter, primarily in a liquid state, but also as 'soft solids' or solids under condition...
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness". For example, hone...
Viscosity - Wikipedia
In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pres...
Turbulence - Wikipedia
In fluid dynamics, a vortex is a region, in a fluid medium, in which the flow is mostly rotating on an axis line, the vortical flow that occurs either on a straight-axis or a curved-axis. Moreover, th...

Jet (fluid)
A jet is a stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle, aperture or orifice. Jets can travel long distances without dissipating. In the Earth's atmo...
Non-Newtonian fluid
A non-Newtonian fluid is a fluid whose flow properties differ in any way from those of Newtonian fluids. Most commonly, the viscosity (the measure of a fluid's ability to resist gradual deformation by...

Supercritical fluid
A supercritical fluid is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve ...
Supercritical fluid - Wikipedia
Superfluidity is a state of matter in which the matter behaves like a fluid with zero viscosity; where it appears to exhibit the ability to self-propel and travel in a way that defies the forces of gr...
Total pressure
In physics, the term total pressure may indicate two different quantities, both having the dimensions of a pressure:
