Why are Pizza Boxes Square?

Image
By

Even though pizzas are round, square boxes are preferred. This is because a square box is made using just a single, cardboard, sheet. While a round box requires several sheets, that need to be joined together using special machinery. So, it is cheaper and simpler to make square boxes. As square boxes can be easily assembled on-site, they are transported in the form of flat cardboard sheets, easily stacked on one another. However, round boxes need to be first assembled. This makes it difficult to transport and store these huge piles of boxes on-site. Further, there are empty spaces around the pizza in the square box, making it easy to lift the pizza slice. The empty spaces can even be used to place chili flakes, oregano, etc.

How Energy conversion from coal is done?

By
Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

How Bulletproof glass works?

By
Shattering the science behind what makes the breakable unbreakable Bullet-resistant glass works by absorbing a bullet’s kinetic (movement) energy and dissipating it across a larger area. Multiple layers of toughened glass are reinforced with alternated layers of polycarbonate – a tough but fl exible transparent plastic which retains the see-through properties of glass. As a bullet strikes the fi rst glass layer, the polycarbonate layer behind it forces the glass to shatter internally rather than outwards.  This process absorbs some of the bullet’s kinetic energy. The high velocity impact also fl attens the bullet’s head. Imagine trying to pierce through a sheet of cotton with the top end of a pencil. It would be very diffi cult compared to using the sharp pointed end. The same principle applies here. The fl at-headed bullet struggles to penetrate the layer of polycarbonate. As the bullet travels through each layer of glass and polycarbonate, the process is repeated until it no l...
