How to See in the Dark

Infrared waves

There is a way to see in the dark using infrared visioning, infrared waves are part of the EM spectrum (electromagnetic spectrum).The EM spectrum is the full spectrum of light not just the small portion that is visible.

In the electromagnetic spectrum the infrared the wave has a frequency range of .003-4*10^14 Hz and a wavelength range of 1mm-750nm. This particular wave is produced by the motion of atoms and molecules in an object. Infrared waves are all around us, they are radiation from sunlight, heat from fire, and animals. There also can be infrared waves that are not hot, they have a shorter wavelength, an example of these waves being utilized around us are in our television remote. Infrared waves are also used in military applications, firefighting, used by the police to find criminals on the run, and even for extermination purposes. An interesting phenomena related to infrared waves is that they move through the atmosphere without heating it until it hits an object. Infrared waves are typically harmless, unless the cops are after you and tracking you with infrared sensors.

Infrared waves have many practical uses today and they are also all around us, they help us feel the all the warmth of the world.

Ever Wondered Why Animals Act So Strangly?

If I were a scientist I would be an ethologist. Ethology is the study of animal behaviors, animals have surprisingly complex rituals, behaviors, and interactions. These individual would do field work in studying the behaviors of various animals in various habitats. Wolves for example have a hierarchy where you have the alpha male and female of the pack and the others respect the alphas by nuzzling to show respect they also have a greeting called the soft muzzle bite.

The reason that this scientific field appeals to me is because animals intrigue me. I wish to learn why animals behave as they do. It is also a desire of mine to explore the wilderness as I study animal behaviors. Although if I was in this scientific field I may have to study animals in captivity. Even so I would still get to learn why animals behave as they do and also how habits and instincts are handed down through generations. I have a mind for psychology which makes my pattern of thinking good for the study of humans and animals and why they have certain behaviors. For the future this field still has a long way to go before we actually figure out the cause for all animal behaviors.
