  1. 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.
  2. What makes an Element?

    My favorite bond is the bond between friends!
  3. The Leyden Jar

    @BrandyBoy72 Yo I think I messed this one up so bad. It was nice knowing you, sorry I could not help you more. My only regret is not being a good person. Farewell, walk free...
  4. Physics Behind a Fly Fishing Cast

    Wow they turned RPG fishing into a real thing!

    @krdavis18 You are the physics duchess!
  6. The Leyden Jar

    As the nature of electricity was investigated into the eighteenth century through static electricity and to a certain extent the triboelectric effect, it was only natural that the discovery of electric charge and capacitance would follow. Independently, three scientists named Ewald Georg von Kleist, Pieter van Musschenbroek and Andreas Cunaeus. A machine of sorts, one that would supply charge through triboelectric electric effect by friction, would transfer the charge to two conducting, metallic foils that act as electrodes, generated a disparity in charge and electric potential. The plates are on the inside and the outside of a glass jar, the glass acting as a semiconductor and because of the electric field, electric potential is created across the glass. This glass would "hold" the charge in a sense. You see, the mystery at the time was the exact nature of electricity. Many believe electricity was some invisible fluid-like thing. Electricity could only be observed from sparks, repulsion and other natural phenomenon so at the time humans were working with an incomplete theory of electricity. However the later two scientists Pieter van Musschenbroek and Andreas Cunaeus identified the mechanism of action that we now know today. The idea is that the inside and outside surfaces of the glass became charged by the foils, equally and oppositely, causing a potential difference across the glass itself as a dielectric. The discovery of capacitance has lead to the advent of a variety of useful modern technologies like computers and circuitry which I hope to investigate at a later time.
  7. Viscosity

    I wonder what causes this? IMFs or maybe solution saturation. Anyways waffles are way more convenient than pancakes. Waffles stay crisp while pancakes absorb the syrup and become ooze-like in consistency.
  8. SpaceX

    He's not. Like a cult, Elon Musk makes false promises to followers and he gets grants from our government for doing nothing. Render this illusion and seek what is yours, the truth.
  9. The triboelectric effect manifests from frictional contact between materials resulting in contact electrification but why? Why are things like this? Why do we live? Why do we die? But anyways here the things we have to know. People have been using this effect like a play thing, charging objects to repel another or zapping frogs apparently (thank you) and I believe it was quite important to our discovery of electromagnetism, especially in the ancient world. If your childhood was at all interesting, you have tried building some sort of potential difference on your person by sliding around on a rug and feeling the power crackle at your fingertips, jolting some poor door knob or family member. That visible stroke of electricity, the spark, indicates to us that there was some level of discharge and depending on the conductivity of the air, it becomes easier to achieve. So when two materials contact they may make a small amount of chemical bonds where one is more likely to receive a negative charge and the other a positive charge due to the inter-molecular forces at play, this is the triboelectric effect. Now that there is some polarity, potential difference is developed and this discovery has had quite an effect in the advancement of the field of physics. Join me for part two: The Leyden Jar in this series.

    But what odes this have to do with physics?
  12. "Semester Review"

    Wow. I appreciate the honesty. I vibe.
  13. Physics in Passengers: Tethers and Zero Gravity

    Yes, the inter-molecular forces are keeping water whole however I wonder does the lack of gravity mean a lack of pressure which in turn would cause the water to vaporize?
  14. You know its just nice to be here, blogging with my physics fellows and learning new things in a great class environment but real talk, before the second quarter closes on all of my fat head, I just wanted to say that I think that these physics blogs are great, an excellent creative opportunity to connect the dots, so to speak, on the physics topics we've learned. However I feel that not everybody is getting enough out of them for their own sake. These blogs while not necessarily throwaways can be taken to their creative limits. This is not English class so I can say "I" and begin sentences with "and" and not get my knuckles rapped with a two-by-four. Blogging can be very social with all the extra features and comment system and these blogs, while requiring a bit of thought, are not going to be scrutinized by anyone outside of the class room so there is not too much pressure to be meticulously detailed and factual, though it is appreciated. My point is these are fun and I wish I heard about them more. One can talk about science fiction theories or how they think the earth doesn't spin (I'm only joking). These really can be what you make of it in the end.

    Wow OK, Mr. Armstrong.
