CHEMISTRY OF CHOLESTEROL AND HEART DISEASES

 CHEMISTRY AND HEART CHOLESTROL- SOURCE- WAVEMAGAZINEONLINE What do we know about cholesterol or what is cholesterol? Cholesterol is a waxy, fat-like substance that are needed to make some useful hormones and is found in our blood. Cholesterol is actually needed to build certain kind of cells, but the it's presence in large quantities can have harmful effects too. It comes from two sources, first, our liver makes cholesterol that we need, the other source is, it can be obtained from food which are derived from other animals. Now, there are two types of cholesterol- 1. LDL Cholesterol- LDL stands for "low-density lipoprotein". This type of parcel protein transports cholesterol from liver to rest of the body, high levels of LDL cholesterol leads to high chances of cardiovascular diseases. It is sometimes referred to as bad cholesterol. 2. HDL Cholesterol- "HDL" stands for "high-density lipoprotein". This type of protein transports cholesterol back to liv

EIFFEL TOWER- POWER OF TRIANGLES

 In this blog, you can learn how architects use mathematics, geometry, other math principles like surface area(might be your favourite), volume, ratios.

GEOMETRY is used everywhere in the world. It can be found from artworks to mobiles, laptops and to the large structures, monuments and buildings. Shapes are the building blocks in architecture. Below are some examples of Mathematics being used in constructing the world!! 

 LETS START-

EIFFEL TOWER(The Triangular Structure)

PARIS, FRANCE

TRIANGLES are the strongest shapes when it comes to building large structures. The triangles are the strongest shapes because of their ability to hold large strength without snapping. If all the three sides of triangle are made equal, then it will be able to distribute the whole weight equally in a large structure.

 The tower is 1063 feet(30,000cm) tall and its construction cost 7,799,401 French Gold Francs(10 crores) in 1889. 

We know the history of the tower that EIFFEL TOWER is situated in FRANCE and it was built in 1889 to celebrate the French Revolution centennial year. The EIFFEL TOWER is very similar to the geometric shapes of a four sided pyramid. At the base, there are four large half circles, one on each side of the tower. Throughout the structure, there are hundreds of triangle and parallelograms. The railings also form perfect triangles.

THE HALF CICLES CAN BE SEEN(BASE)


 How the triangle shapes help the tower?
These triangular shapes provide stability to the structure, it's geometry makes the tower rigid and ideal for framework of a building that needs stability and rigidity.

The tower was built slightly in the wind, but the sun affects the tower more. As the sun-facing side of the tower heats up, the top moves as much as 7inches(18cm) away from the sum.

SOURCE- WIRED

The tower has exactly 186 triangles that gives this massive structure a great strength. Each triangle can hold and indeed helps to hold about 10,000 tons of wieght

WHAT IS A GOOD FUEL?

 GOOD FUELS WITHOUT AN END TO THE BURNING OF FOSSIL FUELS, COAL ESPECIALLY, MOST OF US WILL LIVE SHORTER LIVES. I AM HOPEFUL BUT VERY, VERY CONCERNED  All your questions like- Write it's properties to find whether it is clean fuel or not and  Some commercial uses of fuel, will be answered here, enjoy reading. Some terms before starting- CALORIFIC VALUE- The amount of heat produced by burning a unit mass of the fuel completely is known as its CALORIFIC VALUE. IGNITION TEMPERATURE- The minimum temperature to which a fuel must be heated so that it may catch fire and start burning, is known as IGNITION TEMPERATURE. The definition of a good fuel cannot be given in one line or sentence. There are various conditions that makes a fuel good. We also need to keep in mind that, by saying the term 'GOOD FUEL' we are comparing one fuel with another. None of the fuel can be the best, but can be better in comparison to another. CHARACTERSTICS OF A GOOD FUEL- HIGH CALORIFIC VALUE- A good f
