In economics, physical capital or just capital is a factor of production or input into the process of production, consisting of machinery, buildings, computers, and the like. The production function takes the general form YfK, L, where Y is the amount of output produced, K is the amount of capital stock used and L is the amount of labor used. In economic theory, physical capital is one of the three primary factors of production, also known as inputs in the production function. The others are natural resources including land, and labor the stock of competences embodied in the labor force. Physical is used to distinguish physical capital from human capital a result of investment in the human agent, circulating capital, and financial capital. Physical capital is fixed capital, any kind of real physical asset that is not used up in the production of a product. Usually the value of land is not included in physical capital as it is not a reproducible product of human activity. В2. 01. 7, Capital.

But some daring thieves in Arkansas recently used a forklift in. Why I dont use screen protectors An engineers perspective. Phones are expensive you probably spent a couple hundred dollars on your phone. Plus, you typically sign a two year contract when you buy a phone. So, its worth it to keep your phone in good conditionnot only for potential resale value, but because youre going to have to look at it and use it for a long time. Obviously, there are a couple of things people do to take care of their phones, like use screen protectors and cases. Ill leave cases for another post and discussion, but these are things youre probably super familiar with and may even be using on your phone right now. Theyre cheap and offer an extra layer of protection between your phone and the brutal world that is trying to destroy it. That said, I dont use screen protectors. Why you ask Well, for several reasons. Download Wifi Hotspot For Bb 8520' title='Download Wifi Hotspot For Bb 8520' />First, I suck at putting them on. I cant think of an experience installing a screen protector where I didnt end up with some hideous air bubbles. Second, I dont love the way screen protectors feel. Depending on how much money you spend on your screen protector, they can absolutely alter the experience you have while interacting with your device.

They can be slightly grippier, or softer. For better or for worse, the experience can change. Third, Ive seen a lot of screen protectors that discolor over time. Washington Tuition Reciprocity Program. Im not sure if they collect the oils from your fingers or if its some sort of degradation of the plastic, but your viewing experience might not be as clear as it could be. And lastly, I dont feel like I need it. Phone manufacturers use materials on your devices display that are engineered specifically to not scratch under most conditions. Ill do my best to explain. Material hardness. Download Wifi Hotspot For Bb 8520' title='Download Wifi Hotspot For Bb 8520' />Top VIdeos.

Maybe youve discussed hardness in other situations, but I dont think Ive ever used the word hardness in this context outside of class or some engineering conversation. Regardless, one way that the hardness of materials are classified is by actually using different materials to scratch other materials. In general, a harder material cannot be scratched by a softer material. For example, diamonds are at the top of the hardness scale. I dont suggest you try this, but the only thing youre going to find out there that may scratch a diamond is probably another diamond. However, the gold wedding bands that are held by the diamonds scratch pretty easily. Gold is a pretty soft metal, so there are many materials out there that can scratch it. Therefore, to keep rings pretty, they need to be replated every once in a while. Once, being the nerd I am, I told my wife that her diamond could scratch my proclaimed unscratchable tungsten carbide wedding band. So she tried it out, and now my wedding band is scratched. Anyway. Back to phones. Typically phones these days have glass on their displays, and most have an enhanced glass called Gorilla Glass by Corning Glass. Ive briefly tried to do a little research and figure out how hard Gorilla glass is compared to other materials. According to Cornings spec sheet for Gorilla Glass 3, the glass had a hardness between 5. Interestingly, this is softer than the original Gorilla Glass. If we check out the hardness scale to the right, we see that this value falls under the category of scratchable by a steel file which is typically a hardened steel. This means that anything softer than a steel file like household knives, keys, or coins would likely not scratch your display. In addition to the hardness of Gorilla Glass, Corning uses special coatings on the glass surface to reduce its ability to collect fingerprints and also improve abrasion scratch resistance. So what does this all mean There are limited number of materials that we come into contact with on a daily basis that will actually scratch your phones display. With some easy to learn strategy, you can avoid both using a screen protector and accumulating scratches on your display. Strategy to avoid scratches. Heres what I do I have a designated pocket where a put my phone that nothing else ever goes into besides the occasional plastic pen or chapstick. This could be a pants pocket or a purse pocket. It doesnt really matter. What matters is keeping your phone away from accidental contact with materials that can scratch it like other glass, some rare metals and what I think is one of the biggest display scratching culprits sand. We all know its a thing. Pocket sand can wreck a phone. I know purses get it too. So you obviously need to think this through and make a plan that works for you. I personally am rarely around sand or dirt and never put anything in my designated phone pocket except for my phone, so I havent run into the pocket sand issue. But sand, especially beach sand, is the hard material left over from thousands of years of waves crashing and wearing it down. Its hard stuff and will easily scratch all parts of your phone. When I go to the beach, I put my phone in a plastic sandwich bag and dont take it out until Im sure the coast is clear. Additionally, if you use the same pocket for your phone every time, you wont have to frantically search for it when someone calls. You may even misplace it less. This is a life hack for using your phone thats worked for me and kept my phones pretty. It may work for you, too. The naked option isnt for everyone. Obviously, using your phone without a screen protector isnt for everyone. Maybe youre a lifeguard on a beach or your life circumstances mean youre around a lot of sand or materials that may scratch your display. Or you dont mind the annoyances that come with screen protector use. I have nothing against you. My intention in writing this post is to improve awareness. I feel like there are a lot of people out there who feel like they NEED a screen protector to keep their display scratch free, and thats not the case. Companies have spent a great deal of time and money on research to make your phones glass tougher and more scratch resistant. Some simple strategies or routines can help save you a bit of money and hassle with screen protectors and keep your device pretty.
