Tension may mean: In physics, tension is a force on a body directed to produce strain (extension); it can be considered to be negative compression. It is measured in according units (newton, dynes, pounds-force, etc). Tension is the dominant static force acting on such objects as a vibrating string or a stretched rubber band. Hooke's law states the relation between the stress on an object and the resultant increase in its length. The modulus of elasticity of a spring or elastic string can be use ...

Oddly, the connection between Sudan and Osama bin Laden brought the otherwise undistinguished gum to public consciousness in 2001, as an urban legend arose that bin Laden owned a significant fraction of the gum arabic production in Sudan, and that therefore one should boycott products using it. As a result some food producers, for instance Snapple, renamed the ingredient "gum acacia" on their labels. This story took on somewhat significant proportions, mostly thanks to an article in The Daily Telegraph a few days after the September 1 ...

Your thoughts create your reality.  Science has been studying the correlation between what we think and its effects on physical, emotional, and spiritual well being. There is now a large volume of scientific evidence that our thoughts, beliefs, and emotions produce powerful biochemical that create striking physiological changes in us.

Meditation is simply a form of consciously relaxing. Taking a few minutes each day to "choose to relax", with a little practice you can learn to consciously relax during your daily activities.

Water has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. It is in dynamic equilibrium between the liquid and solid states at standard temperature and pressure. At room temperature, it is a nearly colorless, tasteless, and odorless liquid. It is often referred to in the sciences as the universal solvent and the only pure substance found naturally in all three states of matter. Water molecule - Forms of water. See ...

In mathematics (topology), a surface is a two-dimensional manifold. Examples arise in three-dimensional space as the boundaries of three-dimensional solid objects. The surface of a fluid object, such as a rain drop or soap bubble, is an idealisation.

Cohesion or cohesive attraction or cohesive force in chemistry is the intermolecular attraction between like-molecules. Cohesion explains phenomena such as surface tension. Capillary action for example described in the Cohesion-tension theory related to botany is considered a mix of cohesion and adhesion. Cohesion is produced by the intermolecular forces.

Wetting refers to the contact between a fluid and a surface, when the two are brought into contact. When a liquid has a high surface tension (strong internal bonds), it will form a droplet, whereas a liquid with low surface tension will spread out over a greater area (bonding to the surface). This characteristic of spreading out over a greater area is sometimes called 'wetting action' when discussing solders and soldering. Wetting is often an important factor in the bonding (adherence) of two materials. It is also the basis for

A capillary wave is a wave travelling along a meniscus, whose dynamics are dominated by the effects of surface tension. Capillary waves are common in nature and the home and are often referred to as ripples. The wavelength of capillary waves is typically less than about a centimeter. The dispersion relation for capillary waves is ω2 = gk + (σ / ρ)k3 where ω is the frequency, g the acceleration due to gravity, σ the surface energy, ρ the density and k the wave ...

Evaporation is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. The thermal motion of a molecule must be sufficient to overcome the surface tension of the liquid in order for it to evaporate, that is, its kinetic energy must exceed the work function of cohesion at the surface. Evaporation therefore proceeds more quickly at higher temperature and in liquids with lower surface tension. Since only a small proportion of the molecul ...

In biology and physics, animal locomotion is the study of how animals move, and is part of biophysics. Much of the study is an application of Newton's third law of motion: if at rest, to move forwards an animal must push something backwards. Terrestrial animals must push the solid ground, swimming and flying animals must push against a fluid (either air or water). The topic splits into five disjoint categories: animal locomotion on land (walking and running) animal locomotion in air (bird flight) ...

Capillary action or capillarity (also known as capillary motion) is the ability of a narrow tube to draw a liquid upwards against the force of gravity. It occurs when the adhesive intermolecular forces between the liquid and a solid are stronger than the cohesive intermolecular forces within the liquid. The effect causes a concave meniscus to form where the liquid is in contact with a vertical surface. The same eff ...

In mechanics and biomechanics, tensegrity or tensional integrity is a property of objects with components that use tension and compression in a combination that yields strength and resilience beyond the sum of their components. Animals and other biological structures are made strong by their tensioned and compressed parts. Muscles and bones act in unison to strengthen the other. This kind of strength exists also at the cellular level, and it is a somewhat new understanding of biological structures. Tensegri ...

A bridge is a device for supporting the strings on a stringed instrument and transmitting the vibration of those strings to some other structural component of the instrument that transfers the sound to the surrounding air. Bridge instrument - Sound production mechanism. Most stringed instruments produce their sound through the application of energy to the strings, which sets them into vibratory motion. The strings alone, however, produce only a faint sound because they displace only a small volume of air as ...

The lungs are surrounded by two membranes, the pleura. The outer pleura is attached to the chest wall and is known as the parietal pleura; the inner one is attached to the lung and other visceral tissues and is known as the visceral pleura. In between the two is a thin space known as the pleural cavity or pleural space. It is filled with pleural fluid, a serous fluid produced by the pleura. The pleural fluid lubricates the pleural surfaces and allows the layers of pleura to slide against each ...

Due to an inability to resist deformation, fluids exert pressure normal to any contacting surface. In addition, when the fluid is at rest (static) that pressure is isotropic, i.e. it acts with equal magnitude in all directions. This characteristic allows fluids to transmit force through the length of pipes or tubes, i.e., a force applied to a fluid in a pipe is transmitted, via the fluid, to the other end of the pipe. If the force is unequal, t ...

Soap bubble - Surface tension and shape. A bubble can exist because the surface layer of a liquid (usually water) has a certain surface tension, which causes the layer to behave somewhat like an elastic sheet. However, a bubble made with a pure liquid alone is not stable and a dissolved surfactant such as soap is needed to stabilise a bubble. A common misconception is that soap increases the water's surface tension. Actually soap does the exact opposite, decreasing it to approximately one third the surface tensio ...
