Bluish White color indicates high temperature .Color temperatures over 5000 K are called "cool colors" .
While low temperature has yellowish white through red and called warm colors.The fact that "warm" lighting in this sense actually has a "cooler" color temperature often confused us.
Newton is the first person who introduces Gravity . He was a great Scientist , he also developed the three laws of motion which form the basic principles of modern physics. and His discovery of calculus led the way to more powerful methods of solving mathematical problems.
To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature is -40 degrees (when both the Celsius and Fahrenheit scales are the same) .
The light from the sun looks white. But it is really made up of all the colors of the rainbow. Blue light waves are shorter than red light waves. Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see sky looks Blue most of the time.
All the stars, sun or moon we see is a small portion of this universe. The rest is made of two components. Much of the universe is made of 'Dark matter' and the other is ' Dark energy'. According to scientist only 5% of the universe is made up of Normal matter, 27% is made of Dark matter 68% is made of dark energy.
