WHY SHAPE OF LAY’S IS HYPERBOLIC PARABOLOID?

  Have you noticed that why the shape of Lay’s or Pringles were curve? There is big trade behind this shape. Many calculations and researches were done to bring this hyperbolic paraboloid shape. This shape prevent the Pringle from crack and this brings an extra crunch on behalf of taste of Pringle.
"The use of hyperbolic paraboloids as a form of thin shell construction was pioneered in the post-war era, as a hybrid of modern architecture and structural engineering. Being both lightweight and efficient, the form was used as a means of minimizing materials and increasing structural performance while also creating impressive and seemingly complex designs," states  design building. 
   There are two principle of curvatures meet each other at zero point is known as saddle point or minimax point. These double curvature prevent a line of stress which avoid crack and brings structure strength despite their thin shape . Usually the weight of Pringle not exceed 150grams. 
   This made the companies to reduce their loss and improve them to export distance countries. As the curve shape help to withstand the pressure from external.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is

The Oldest Phone In The World

  The first cellular telephones are called Dyna Tac. It is manufactured from 1983-1994. It received approval from the U.S. FCC on September 21, 1983. Martin Cooper of Motorola made the first publicized handheld mobile phone call on a prototype DynaTAC model on April 3, 1973. This is a reenactment in 2007.    The dimensions of this phone are 3300 x 898 x 445 mm, vol. 1318710 cm³.This cellular phone is available at the minimum weight of 2 pounds. It is used in the ALOHAnet system, including metal–oxide–semiconductor (MOS) transceiver and modem technology. It has nine additional key.They are Rcl (recall),Clr (clear),Snd (send),Sto (store),Fn (function),EndPwr (power),Lock and Vol (volume).Minimum sim is used in this phone. In 1983, The market price for this phone is $3,995.   In 1930, Travelers could place phone calls from and to ocean liners in the middle of the Atlantic Ocean. The process was driven by Marine VHF Radio and cost $7 a minute. In 1984 Motorola DynaTAC 8000X wa
