 Engineering Drawing/graphic tools

Drawing is the language of engineers. Thousands (1000) of words cannot describe a part correctly which a single drawing represents accurately. Ideas of engineers are recorded by preparing a drawing, and execution of work is also carried out on basics of drawings. Communication of engineers is done with the help of drawings. Like music, drawing is an universal language of the engineering world.


Drawing instruments are used to prepare drawings easily and accurately. The accuracy of drawings depends on the quality of instruments. Desirable accuracy is only possible with quality instruments. It is therefore necessary to obtain the instruments of superior quality.

Is it time travel possible!

The possibility of time travel has fascinated scientists and storytellers for centuries. While time travel remains a staple of science fiction, physics does provide some theoretical possibilities. Read More Our Solar system Earth vs Mars Is it time travel possible! Space-Time Fabric The Unity of the Universe Theoretical Foundations 1. Einstein’s Theory of Relativity According to Einstein's special relativity, time dilation occurs at speeds approaching the speed of light. A person traveling near light speed would experience time much slower than someone on Earth. This is a form of "forward" time travel. General relativity allows for the possibility of time warps due to massive gravitational fields, such as those near black holes. 2. Wormholes Wormholes, or Einstein-Rosen bridges, are hypothetical shortcuts through spacetime that might allow for time travel. However, they are currently theoretical and would require exotic matter to remain stable. 3. Closed T...

Discovering Tut: The Saga Continues explaination

  CHAPTER – 3 English class 11 hornbill Discovering Tut: The Saga Continues  ­ A.R. Williams Summary A powerful dynasty ruled Egypt.

He smashed the images of Amun and closed its temples. During his ...
