WATER and ITS MEANING

WATER and ITS MEANING Post 113 --by Gautam Shah  . Water is a great cleanser, it washes, and therefore heals and purifies. It softens so dissolves and penetrates everything. It nourishes and enlivens, and so satisfies. Our Earth, our body and all organisms contain 75-80% water, as the constituent matter.
Water is in dynamic equilibrium as its heat content is continuously balanced by transition from gas to liquid to gas at ambient temperatures. It is rarely pure, always has something, mainly salts, dissolved in it, varying its behaviour and the electrical properties. It has good cohesion and adhesion and capillary action. Water has a high dielectric constant, giving it an ability to make electrostatic bonds with other molecules, meaning it can eliminate the attraction of the opposite charges of the surrounding ions.
Air and Water are our two basic realities. The air begins and ends our conscious life, it is invisible and we realize its presence when we consciously breathe it. The encounte…

TOOLS and TECHNOLOGIES -1

TOOLS and TECHNOLOGIES -1 Post 112by Gautam Shah ➔
Humans developed a capacity to touch the digits of hand fingers with the thumb, along with the formation of hand tools. It substantially added to the capacity to coordinate tasks, power of observation and learning. First tools like sticks, extended the reach and handling ability. Small objects became target throwing tools. The wrist, palm, thumb and fingers, all in coordinated manipulation improved the human the task capacities.


The oldest known tools date back to 26 00 000 years. For 20 00 000 years, rock chopper was the only tool for cutting and scrapping through the skin and sinews of the hunted animal, until hand axe, a superior version of the chopper appeared.

The chopper was just a fist-sized rock, chipped on one face, to form a roughly toothed but sharp edge. It was the only tool, till a superior tool the handled axe was devised. The stone edge of the handled axe was chipped all around, so was sharper and more effective than ea…

FINISHING TECHNIQUES for MATERIALS

FINISHING TECHNIQUES for MATERIALS Post 111by Gautam Shah ➔
.
Large number of surface finishes evolve during the manufacturing of materials. These are self finishes, so integral and permanent. Surface-finishes are also obtained by treating Natural materials and secondary processing of Manufactured materials. Assemblies of materials require modification of their surfaces, or a new finish to overcome-equalize the surface quality, and manage the disorder caused by the joints.
There are essentially four methods for creating Surface Finishes. To achieve a finish for sensorial or technical requirements, one or several of these methods, are used. .
1 Techniques for surface finishing from the object itself.
2 Techniques for surface finishing with application of foreign materials.
3 Techniques of micro material deposition (same or foreign) for surface finishing.
4 Surface modification by secondary processing. .
It can also be said that finishes are created by physical or chemical alteration of the su…
