We do not need to plan or devise a "world of the future"; if we take care of the world of the present, the future will have received full justice from us. a good future is implicit in the soils, forests, grasslands, marshes, deserts, mountains, rivers, lakes, and oceans that we have now, and in the good things of human culture that we have now; the only valid "futurology" available to us is to take care of those things. we have no need to contrive and dabble at "the future of the human race"; we have the same pressing need that we have always had - to love, care for, and teach our children.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
