Today's post is more related to mathematics, as you can tell from the title. I'll be telling you about the amazing solid shape, the octahedron. WHAT YOU WILL LEARN TODAY : We will have found-  -->The derivation of the formula for the volume of the octahedron. -->The ratio of the volume of an octahedron when placed inside a cube with its vertices touching the centers of the faces of the cube and the volume of the cube.  So! Let's begin! You will have to understand platonic solids first. PLATONIC SOLIDS: Platonic solids are five geometric solids that have congruent and regular sides that meet at three-dimensional angles.  Plato used them to explain the structure of the universe. Hence, the name 'Platonic'. There are five Platonic solids:  the tetrahedron with four faces,  the cube with six faces,  the octahedron with eight faces,  the dodecahedron with twelve faces,  and the icosahedron with twenty faces.   They are used in many fields, including biomedical rese...

HOW FAST DOES LIGHT TRAVEL? If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. This is because the speed of light is as fast as 300,000 kilometres per second or 300,000,000 metres per second . The speed of light in a vacuum is 186,282 miles per second or 299,792 kilometers per second , and in theory nothing can travel faster than light.  This is the cosmic speed limit, and the constant that stands for the speed of light in vacuum is known as 'c' or 'celeritas'. BUT CAN ANYTHING ELSE TRAVEL AT THE SPEED OF LIGHT? Quarks, leptons, neutrinos, and even dark matter all have masses as a property inherent to them. Objects made out of these particles, such as protons, atoms, and even human beings all have masses as well. As a result, they can approach, but never reach the speed of light in a vacuum. No matter how much energy you put into them, the speed of light, even in a vacuum, will forever be unattainable, and nothing...

Have you ever heard about General relativity?  General relativity is a remarkable theory published by the well known physicist Albert Einstein. Let us know more about general relativity. General relativity is the geometric theory of gravitation published by Albert Einstein. Albert Einstein published this theory in 1915. It is the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation , and gives a unified description of gravity as a geometric property of space and time, or space-time . THE CURVATURE OF SPACE-TIME AND THE EINSTEIN FIELD EQUATIONS The  curvature of space-time is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations. That is a system of partial differential equations. The Einstein field equations comprise a set of 10 equations in Albert Einstein's general theory of ...

A molecule actually is an  electrically neutral abstraction of two or exceptionally more corpuscles held together by material bonds. Molecules are fairly distinguished from subatomic particle by their lack of truly electrical electric charge. However, in quantum physics, natural philosophy, remarkably organic fertilizer chemistry, and biochemistry, the grammatical constituent molecule on the whole is often pretty much used less strictly, also notably being applied to truly polyatomic ions. A diatomic atom kind of is really composed of only two materials, of the strikingly same or elementally different chemical elements. A fundamentally heteronuclear elementally diatomic molecule consists of two of speck of the same element combined

WHAT IS AN ATOM? An atom is the smallest unit of any regular substance which has chemical properties. All solids liquids, gases and plasma consist of neutral or ionizing atoms. Subatomic particles There are subatomic particles as well, which are smaller than the atoms.  All atoms consist of three types of subatomic particles, which are: • protons • neutrons • electrons . Arrangement of the atom The protons and neutrons form the center of an atom together form what is called the nucleus.  The electrons fly around the nucleus into a small cloud. There are many kinds of atoms. Each atom has a unique name, atomic weight and size. WHAT IS A MOLECULE? A molecule is made of a group of atoms which are bonded together. It is the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. It is the group of multiple atoms which form the smallest unit into which a pure substance can be divided while retaining its composition and chemical properties. A...

Velocity is a vector measurement that represents the rate at which an object changes position. Velocity ​​measures how quickly something moves in a certain direction. For this, velocity must be interpreted as a measure of a physical vector quantity. You need size and orientation to define it. For example, if an object moves northward at a speed of 5 meters per second (5 m / s), the velocity can be said as 5 m / s to the north. The velocity of an object is the rate of change of position relative to the reference system and is a function of time.

Speed ​​is the distance traveled per unit of time. This is how fast the object moves. You can measure the speed. At higher speeds, objects move faster. Lower speeds mean slower movement. If you don't move at all, the speed is zero. The SI unit of speed is m / s (meters per second). Kilometers per hour or miles per hour is a measure of total speed. The sea knot (or nautical Mile) has a common speed that is per hour. Speed ​​= distance / time = d / t
