COMMENT ABOUT THE VIDEO
The video is related to the metrology because metrology is the science of measurement, and the video shows a machine that can be controlled from a boat by people with a great precision without this mistake. This can only be accomplished with scientific progress and accuracy of data provided by the people so that the machine does not make mistakes. This is helpful in places where man can go and need a robot to do the work conducted by some scientists or peoples to provide data and accurate measurements. This would help better use of natural resources and people’s lives.

HOW IT’S MADE

This documentary is about how the process of making some objects we use and they do not pay attention to how it is made and that are made. First you talk about how the swords are made in a long manufacturing process. mold making metal swords which are then polished, then heated and immersed in another liquid cold for the swords have higher hardness and does not break easily. After given the swords edge that ultimately makes the grab. These swords are sharp enough to cut paper and resistant to not suffer damage when striking the metal.

The second object of the speaker is on a boat which is made of several sections of metal that is bent and welded to the desired shape, then applies pressure inside are to check for leaks. Placed after the upper levels where the helm, the chairs and the driving force behind the boat at high speeds.

The third object of the speaker is the grandfather clocks operating at travez of gravity. These watches are manufactured primarily of wood, gun where it is placed under watch. All parts are attached with glue and screws, then sanded the frame that gives shape desada. finally is painted where it is placed under the pendulum and clock parts such as needles and the weight.

The fourth object is a fuse and the long process it takes for the manufacture of this element, like welding parts and electrical appliances for testing to see its operation.

comment nanotechnology

The video discusses the nanotechnology material that studies and develops very small and is fundamental to everything that exist. comparing it with the theme of materials science nanotechnology helps develop new and better technologies to facilitate our daily lives, making smaller objects and better performance.
