For whatever the reason, we have a giant and extremely dense sphere of hydrogen in the sky called the Sun. How lucky for us this is, since the Sun is constantly undergoing Nuclear Fusion and cranking out megatons of solar energy on a regular basis.
This solar energy arrives to Earth as electromagnetic radiation, where it is absorbed and utilized in the biosphere in numerous ways. The Sun and solar energy it emits is arguably the most essential element to our existence.
Electromagnetic radiation is composed of tiny invisible energy waves, all traveling at the speed of light (3x108 meters per second). Forms of electromagnetic radiation include X-rays, gamma waves, radio waves, microwaves, infrared waves, ultra-violet waves, and the visible light spectrum. The only difference between the waves is their frequency of resonance, and they are characterized based on this.
The Sun emits solar energy in the range of infrared, visible light, and ultra-violet wave lengths. Thank goodness for this, because if the Sun emitted solar energy as X-rays or Gamma rays, we would all be toast.
Solar energy is also the primary element that forms weather patterns. The Sun warms the surface of the earth, whereby wind patterns develop. Solar energy is absorbed in the oceans, and this helps form the currents. Evaporation caused by solar energy is what fundamentally leads to clouds and thunderstorms.
And so it is no surprise that solar energy is at the root of almost all physical processes that occur on Earth. Without this valuable resource life as we know it would not exist.

 Every now and again, I find a gem of a clip that seems worth sharing. As we head into the 4th of July weekend, I thought I would leave my readers with a little humor. The video, which is found below, is presented by a Professor who believes in using classical music to grown your brain.
Just like many other muscles, in the human body, the mind is something that needs to be exercised daily in order to keep healthy. This might mean reading a book, engaging in conversation, or doing some mind exercises.
Now, our delightful presenter takes his work seriously. It also makes you chuckle a little bit, because he challenges you to sing along to the a favorite patriotic song while doing hand and face movements. So, what are you waiting for? Start your holiday weekend by challenging yourself to some brain activity!
Happy 4th of July, my wonderful readers!
