How do Airplanes flies ?

Introduction: Airplanes have revolutionized modern transportation , allowing us to traverse vast distances quickly and efficiently. But have you ever wondered how these colossal machines take flight? In this blog post, we'll delve into the fascinating science behind aviation and explain how airplanes soar through the skies. Aerodynamics: A key concept in understanding flight is aerodynamics. This branch of science deals with the study of air in motion, particularly the interaction between the aircraft and the air it moves through. Lift: Lift is the force that allows an airplane to overcome gravity and ascend into the sky. This ess ential force is generated primarily by the wings. Here's how it works: Shape of the Wings: Airplane wings are carefully designed with a curved upper surface and a flatter lower surface. This shape creates a pressure difference, with lower pressure on top and higher pressure on the bottom. As a result, the airplane gets pushed upward, creating lift. ...

Li - Fi technology is Better Than Wi - Fi ?

👀 What is Li - Fi ?                                      Basic Principle : Li-Fi technology operates on the principle of visible light communication (VLC). It uses light-emitting diodes (LEDs) to transmit data by modulating the intensity of light at high speeds. This modulation is typically imperceptible to the human eye. Advantages : High Data Rates : Li-Fi can achieve data transmission speeds of several gigabits per second, which is significantly faster than traditional Wi-Fi. Security : Li-Fi is considered more secure than Wi-Fi because light cannot penetrate walls, making it difficult for hackers to intercept signals. No Interference : Since Li-Fi uses visible light, it does not interfere with radio frequency (RF) devices, making it suitable for use in environments where RF interference is a concern. Components : LED Bulbs : These serve as both lighting sources and data transmitters...

The Real Age Of Universe !

👀 The Real Age Of Universe !                                   Cosmic Microwave Background (CMB): The CMB is faint radiation that fills the universe . It's like a leftover glow from the Big Bang, the event that created the universe . Scientists have studied this radiation using specialized instruments. Expansion of the Universe: Scientists have observed that galaxies are moving away from each other, which suggests the universe is expanding. By tracking this expansion backward in time, they can estimate when the universe started. Hubble's Law: Astronomer Edwin Hubble's work led to the discovery that the universe is indeed expanding. By measuring the speed at which galaxies are moving away from us, scientists can calculate how long it has been expanding. Big Bang Theory: Combining all these observations and measurements, scientists developed the Big Bang Theory. It's like rewinding a movie to its s...
