🤔 How it works …….. ⁉
How a how a seismometer works
A seismometer is a device that is sensitive to vibrations. It works on the principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement.
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest “seismoscope” was invented by the Chinese philosopher Chang Heng in A.D. 132. This did not, however, record earthquakes; it only indicated that an earthquake was occurring. The first seismograph was developed in 1890.
😳Why❓❓❓
Why don’t most Indians cross the road when a cat crosses their path?⁉
Well, in olden days people used to travel by carts that were pulled by domesticated animals.
When passing through forests at night, the carriage animals used to get scared and act chaotic when they sensed wild cats such as leopards, cheetahs, and tigers crossing their path.
The travellers warned others not to proceed when a cat passes their path.
