Overview:
Why have I decided to include a physics section in addition to the atomic
theory section? Because physics covers so much more than atomic physics
and chemistry. Physics can cover all energy, objects, and matter in
our known universe. Other than possible quantum theory, physics can help describe our known
universe at micro and macro levels and the laws of physics are applicable
at atomic and larger levels. Of course, physics abounds with theory
since behaviors of some matter may seem peculiar and awkward to describe
in terms of Newtonian Physics. Some examples include Fermat's theorem,
wave theory, and particle theory. Since I discuss physics throughout
this website (just search it above), I have decided that a dedicated
section would be appropriate. Of course, Newtonian Physics have obvious
applications in aerospace. We have used momentum, inertia, and gravity
to aid many of our spacecraft in their travels rather than fuel consumption.
When possible, it is nice to utilize these concepts for efficiency,
though convenience and efficiency should be weighed.

Objects:Objects are subject to laws of physics and share a lot in common with quantum particles. Gravity is another of the 4 fundamental forces in our know universe. So both light and objects are subject to laws relating to gravity and motion. Gravity can bend light, and an orbiting spacecraft bends around the earth in a theoretical perpetual state of free fall. An object may bond to other objects magnetically, or through gravitational pull. At atomic and molecular levels, bonding likewise can occur within the confines of the fundamental forces. These bonds may be called by several names depending on the types of bonds. And of course, objects can be bonded with "glues" whose chemistry operates on the objects at molecular and atomic levels. So as you can see, though the laws of physics may be well understood, the application and implementation can be extremely tedious and difficult. And as with any science, testing and empirical evidence is critical in developments. |
Nuclear Force:The last two of the four fundamental forces are nuclear forces. I will not entertain these forces here, but wanted to point them out for completeness following the preceding sections. |
Light:Light is simply defined as a tiny band within the electromagnetic spectrum, that the human eye can perceive. Animal life may have differing capabilities when it comes to light perception. How this light is perceived is quite fascinating. I will not go into too much detail about transmissions through various media of the eye, but I will briefly touch on the receptors that transmit neuro signals. These receptors possibly operate within RGB individually. So one set of receptors may receive red, another green, and the last - blue. Much like photovoltaic technology or cochlear transception, these receptors are simply excited in these ranges and we name them, and we name the combinations in terms of color. White is transmission of all these colors, and black is lack of transmission in the visible range. Since light describes a broad band relative to that of a laser, it tends to scatter its containing colors through cross interference. Interestingly, ultra violet and higher frequencies will transmit further through various media! So you can get a sunburn as rays penetrate into skin and you can view bones with x-rays. This may be broad and general since like color, some media transmit, absorb, or reflect different bands based on its properties. So if you have read all the sections on this page, you should have a pretty good understanding of your universe. If you don't, read some of the other sections throughout this website as well. |
Summary:As I have pointed out previously, the physics of our universe is pretty well understood - at least theoretically. The math, application, and implementation are completely different however. I have included a math & measure section which you may want to read. Science, physics, and chemistry require an understanding of higher math. It is that simple! You need to be able to make measurements, record these measurements, then make predictions, assertions, and interpretations based on mathematical formulas. The more you know going into an experiment, the better your chances of successful learning. You will likely have less waste as well by approaching your experiments with great thought, hypotheses, and theory. And of course, as with all summaries throughout this site, I will begin conclusions toward space endeavors. Though I argue extensively throughout this site that tourism could generate billions of dollars for space travel, the first pioneers will disproportionately be scientists, engineers, and developers and will need initial R&D funds. The reason should be evident. These are the ones that will be pushing many thresholds and fronts to enable broader space travel and colonization. We are going to be interested in life sustenance, exploration, and resource discovery. Having said this, I push for the day when local colonization and tourism will be more affordable. We certainly have the technology and history for reasonably safe spaceflight right now and for orbital flight and stations. Ultimately, the adventurist and tourism consumer will likely fuel space endeavors very broadly. |
