    So according to some scientist from another time. Each of an atom's electrons inhabits some energy level in the atom's orbit. To ascend to or descend from one of these, that electron must emit a photon of a specific frequency as a form of energy. One could think of this like an electron living on a floor of a building of many stories. To move up or down, signifying a change in energy, an electron must receive or emit a photon of an energy corresponding with the floor or energy state that its in. This minimum energy to move the electron is a quanta of electromagnetic energy. I believe we will be exploring this further in chemistry and id be happy to report back!

    It has occurred to me that I may not be the only one scrambling to type two or three or more blogs today. This is no one's fault, the blame rest on me alone but I wonder at the amusing possibilities that I have avoided by doing these blogs. The dread and anxiety that I could have curbed if only I had been more resourceful or the high-minded topics I would have espoused if only I had the impetus, speaking of astronomy and physical laws and their implications. I should start now, yes, Earth is the third planet from the Sun and its sufficiently heated for water to be in liquid form which gives it its life-giving properties. The charges of the individual atoms of water gives it the surface tension it needs to have the capillary effect, the specific heat capacity to not freeze or evaporate too readily and bring things into solution. Really, the chemical properties are emergent properties of the underlying physics. I guess that's all I came up with for now.

    We consecrate thanksgiving in the abundance that has come to us, not in vainglory but of thankfulness for our lot in life. With a class of a few, we know each other by name and are never far apart. These blogs keep our thoughts fresh and physics at the forefront. Really, AP physics C is a paradise. The packets are straightforward and with a bit of searching, the answers are conveniently there with little confusion on the whole. Our equations are adequate and fulfilling, they are means to an end and I am thank that my forebears had thought them. Thanks, to my teachers and my peers. This year will be worth it!

    An atlatl or spear thrower is one example of mankind's inherent knowledge of throwing spears well. The throw or "casting" involves acceleration, force etc. but the precise action that our mechanisms enhanced our early projectile weaponry is remarkable and telling of humanity's ingenuity. This device acts like an extension of the wielder's own arm amplifying the leverage, involving elements of the center of mass and whatnot, of the throwers arm and wrist. It also improved upon the stability of the cast using a rigid piece of wood or perhaps bone for an an atlatl instead of relying on the muscles of the arm. This balance in the throw is particularly important because the most effective strikes are delivered forcefully at the point of the spear, more pressure is applied at the very narrow end because of force per area. A selection of darts may use fletching to balance the projectile and these fins provide good lift or thrust due to air resistance. The amount of thought that our forebears put into killing things is notable because it is a point towards hallmark qualities that man has that animals do not, our high motivation and ability to plan. This is at the soul of humanity and I believe this is important to understanding our heritage and natural intuition as it is for supplementing our understanding of physics.

    I had a very thought provoking conversation with some fellow students in the spare time of seventh period. The subject of some debate was the true nature of the atomic elements. We are talking of the chemical elements of the periodic table, nothing to do with Avatar: The Last Airbender, one of the greatest animated shows to grace our planet but I digress. Atomic manifest their properties from protons and electrons. A nucleus of protons, positive charges, tends to attract an equivalently charged quantity of electrons, negative charges, that occupy energy levels. Energy levels are stratum of electrons a certain radius from the positive proton nucleus. It follows that a relatively large positive charge would attract a large amount of electrons for multiple energy levels and a wide radius. Only certain discrete amounts of electrons can occupy  an energy level but generally those closest. Now that the groundwork has been established, we can discuss how certain period groups have their properties in a part two.

    I was watching this video of a man slapping a molten stream of metal. Let there be no doubt that this fiery stream was beyond glistering, the scathe of flesh and branches, such that man has never seen. Anyways it was bizarre because his hand passed through unscathed, leaving nary a mark. Perplexed, I began to think and when I could not find any bulletproof conclusions I searched the vast corners of cyberspace to discover the existence of what is called the Leidenfrost effect, there before my eyes. In short, when a liquid contacts a surface of far greater heat than its self, the outermost layer of the liquid will boil into naught but a layer of vapor, insulating the whole from heat. The man must have had some sweat or the like on the surface of his skin and when they came in contact with the hot metal the vapor formed a vapor and under the aegis he was not harmed. This phenomenon can be observed when dropping water on a hot pan, they scatter because of this vapor.

    The symbol of invention, ingenuity and enlightenment, the light bulb is perhaps a most pivotal invention in the course of human history. The advent of the lamp made it possible to render the dark of night and shed a lambency on the way to the future! Truly, the light bulb is all we could ever ask for. They say 'teach a man to fish and he will not have light but teach a man of the fluorescent lamp and he will have that light!' but in all seriousness let us illuminate the obscure nature of the fluorescent light! Different varieties of the fluorescent light may use cathodes of tungsten that release heat and electrons while being electrically heated itself and this provides the energy needed to produce the 'lighting' effects.As I have said once before in my previous blog about atomic energy levels and their associated light spectra, it was a consummation of this knowledge that we make an effective application of phenomena. A electric current passes through the mercury gas, exciting its electrons and emits high energy light as they descend to ground level. That energetic lights strikes a phosphorescent or fluorescent salt, the white powder inside the glass tube, which emits light itself. A mixture of noble gases which ionize as a result of the heat being generated by the cathodes, allowing sufficient current to excite the gaseous mercury. All these components make for an expensive assembly and their complexities make them a challenge to manufacture which results in a unattractive price. However they are known to be many times more efficient than their incandescent cousins, saving money and electricity in the long term. Fluorescent bulbs are also a environment friendly choice, while containing mercury, the construction of incandescent lamps actually produce more mercury waste.

    In AP Chem, my schoolmates and were using a colorimeter to measure the absorbency of certain concentrations of a colored solution. I notice how any color of light, except for the color of the solution, would be absorbed an amount proportional to the amount of solute disassociated in solution. I wondered why this was? A red solution would absorb blue or green spectrum of light but not red light, in fact from the reading of the colorimeter it would seem that an incarnadine solution would emit red light, give us a negative absorbency constant.  A relevant bit of information would come from the fact that a perfectly white-colored object may reflect all incoming light and a perfectly red colored object would reflect only red light and a dark object would absorb all incoming light. Imagine a ruddy colored mineral, if a blue or green light shone on it the mineral would appear nearly black because it absorbs the light spectrum however if a red light shone on its face it would appear as a brighter red. This was a revelation that occurred to me late Friday during that lab and I would hope that it proffers someone, somewhere some insight into the nature of light. @BrandyBoy72

    At the time of writing the Magnetism unit has come and gone and perhaps writing this is more for show than anything. Nevertheless, I have something to prove by showing the internet that for a mediocre high school student I can be resourceful yet in paraphrasing the magnetism Wikipedia page. It is enough to know the math of something and then venture to take an exam where the capability to succeed is at your fingertips but the concept of magnetism defines the models that work, so the underlying mechanism of magnetism is a pressing issue indeed. In the ancient world, magnetism is observed in naturally occurring lodestones, magnetite and iron alloys whereupon the natural philosophers of bygone times poured over speculations and experiments formulating the modern model that our current science is based on. So what I can grasp of magnets is that electrons have a quantum angular momentum directed in a certain way. This angular momentum is intrinsic and because the Pauli exclusion principle, no two electrons with the same spin. So imagine the mass movement of an uncountable number of electrons oriented the same way there would be a larger magnetic movement throughout the material which is normally iron and thus creates ferromagnetism.

    Mechanical waves move through matter as a medium and as such many of the natural laws that pertain to motion and dynamics have special places in the study of mechanical waves. One type of wave is sound which most easily propagates through air however because of the laws of momentum one could expect that a mechanical wave is maintained through any matter. A solid barrier for example would be so rigid that it would absorb the impact of a wave and impede passage slightly beyond the barrier. This would produce a sound shadow where the sound loses its momentum in passage through the solid. 
    Anyways this is the last blog post. Thanks FizziksGuy, even in the darkest of nights, you were by my side all along, my true mentor,
