COMMON CURVES USED IN ENGINEERING PRACTICE

In engineering practice we see many objects having curved surfaces or edges. Every curve has a name and property which defines it. Point is the basic identity in a drawing. All curves are obtained by the path traced by a point while moving in a constrained motion. Most commonly used curves in engineering practice are 1.    Conic Sections: – These are the curves obtained on having sections of a right circular cone by a plane from different positions relative to the axis of cone. Circle, Ellipse, Parabola and Hyperbola are the curves defined by conic sections. 2.    Cycloidal Curves :-…

INTELLIGENCE IN PLANTS

Do you remember the Scarecrow from the story Wizard of Oz? He was clever without a brain, and so are plants. Plants are modular organisms, capable of learning, remembering, and making decisions. In their own pace of life, plants take the most of their environment to make intelligent choices. A not-so-quiet life Historically, people used to see plants as passive automatons. The term ‘vegetative’ used to address humans with cerebral death is a vivid example of this mindset. Indeed, plants are sessile organisms.
