First order of business today was Algebra. I learned about common logarithms. Basically, any logarithm with base 10 is a common logarithm. That’s it. That’s a common logarithm. I don’t know what else to say.
Next up, Sociology. I learned about the interaction of technology and workers. With a lot of technology, workers can do stuff at their jobs besides working, and those things can be important. Stuff like scheduling doctor’s appointments, sorting out groceries, and so forth. However, people can use technology to slack off even further, as you do.
There are also concerns with the fact that the internet is forever. Stuff you post online might cost you a job one day.
Finally, Programming? Well, everything is done for programming! So we’re doing more English! Interesting thing I learned, different people have different levels of immersion in something. Researchers have found that people have an “absorption trait”, which means that they’re quicker to be drawn in and fascinated by something. Some people also willingly suspend their disbelief, in order to be immersed.
First order of business today was Marine Biology. I learned about horizontal distribution of animals. Interesting thing, epipelagic habitats can be differentiated by what species of krill lives there. There are six closely related kinds, and their distribution indicates what other animals live in the area.
Next up, English. I continued reading the video game essay, and a bit part of spacial presence is consistency. Namely, another four things. Lack of incongruous visual cues, consistent behavior from things in the game world, an unbroken presentation of the game world, and interactivity with items in the game world.
Some of those are self explanatory, so let’s cover numbers one and three. Lack of incongruous visual cues means that things look how they “should” look in a game. Tutorial messages don’t pop up while you’re doing things and break your immersion. As for an unbroken presentation, that’s similar in that the game world remains there, it doesn’t just go away like when you get stuck in a loading screen.
Finally, Algebra. I learned about properties of Logarithms, and relatively speaking they’re pretty simple. Since logarithms are exponents, the properties of logarithms can be derived from the properties of exponents. The product property of logarithms, for example, states that the logarithm of a product is the sum of the logarithms of its factors.
First order of business today was Algebra. I learned about logarithms. They’re complicated. So, in general, the inverse of y = bx is x = by. In x = by, y is called the logarithm of x. Also, it’s usually written as y = logbx, and is read as y equals log base b of x.
Next up, Sociology. I learned about voluntary organizations. Basically, they’re groups where the members join and organize because of a mutual interest. One of the things I find really interesting is that the leadership of such an organization is often a very closed circle. The leaders select the next set specifically, and so on, even when there are supposed “elections” going on.
Finally, Programming. I looked at voltage limitations, and as far as I can tell, you need special equipment to figure it out, or in a lot of stuff the maximum voltage will just be listed.
First order of business today, Algebra. I learned about exponential functions. So, in an exponential function, the base is a constant and the exponent is a variable. There are also exponential equations, which are equations where the variables occur as exponents.
Next up, Programming. I looked at the usage of an LED circuit in some Internet of Things scenarios. For example, you could have a circuit that turns on a light if a signal stops being transmitted. For example, you could have a little, battery powered fan that you want to keep on. If you somehow hooked it up to the internet of things, you could have a light go on if the fan ever goes off.
Finally, Sociology. I learned about bureaucracies, and something I find interesting called the Peter Principle. It’s not true in most cases, but it basically states that people in an organization are promoted based on competence. If they do their job well, they are promoted and given a different job. The problem there, however, lies in the idea that they will continue to be promoted until they are incompetent at their job. Thus, leaving an possibly useful worker in a position where they can’t do much.
And we’re back! My spring break trip was fun, got to see DC, spend some time with family, go on a little road trip. All in all, in a good time. Now, back to schoolwork.
First order of business today was Algebra. I learned about solving rational equations and inequalities. So, a rational equation is, in general, any equation that contains one or more rational expressions. Inequalities that contain one or more rational expressions are rational inequalities. As for solving the two, it can be somewhat complicated, but you generally start with one thing: Any values that make the denominator zero, you can safely exclude.
Next up, Marine Biology. I finished the lesson on coral reefs. What I find interesting is just how big they can be. They’re actually big enough that wave force, water depth, and even temperature can vary quite a bit between different parts of the reef, which can affect what animals live where.
Finally, English. I started looking at reality in fiction, and found an interesting essay on a Sherlock Holmes pastiche. The Seven-per-cent Solution has a foreword, which essentially states that it is an unpublished manuscript of Watson’s, presenting him, and all other characters by extension, as real people.
First order of business today was Algebra. I learned about classes of functions. So, some of the different kinds of special functions I’ve been studying are constant functions, direct variation functions, identity function, greatest integer functions, absolute value functions, quadratic functions, square root functions, rational functions, and inverse variation functions.
It’s a big list.
Next up, Sociology. I learned about the rationalization of society. Basically, how society evolved to it’s present state, and it actually looked at it from an economic perspective. With the rise of capitalism, a lot of changes came along with it. People are hired to do work, production relationships are based on contracts, and so on. Karl Marx noticed that traditional business practices were gotten rid of in favor of rational, capitalist ideas.
Finally, Programming. I looked at one of the career and technical student organizations at Georgia College, the Association for Information Systems, or AIS. They actually do some cool stuff, like get students more up to date with the ability to use some tech, and meet with recruiters for jobs and such.
And now, a little notice. There won’t be any new posts tomorrow, or next week. I will return the following week however. That is all.
First order of business today was Algebra. I learned about direct, joint, and inverse variation. Kind of interesting stuff, here’s a summary;
A direct variation can be expressed in the form y=kx, where the k is a constant, called the constant of variation. Y varies directly as x if there is some nonzero constant k, such that y=kx.
Joint and inverse variation are similar. In joint variation, y varies jointly as x and z if there is some number k such that y=kxz, where k, x, and z are not 0. For inverse variation, y varies inversely as x if there is some nonzero constant k such that xy = k, or y = k/x.
Next up, Sociology. I learned about groupthink, which is basically the principle that in a group, people tend to present themselves as thinking alike with the rest of the group, in order to avoid conflict. It can have really bad consequences, like the widespread belief that the United States could never be attacked at Pearl Harbor.
Finally, Programming. I learned about Zigbee. It’s a technical standard for wireless communication, mainly used for small scale projects. Fun fact, the name is actually based on the waggle dances of honey bees. I just find that interesting.
The first order of business today was Algebra. I learned about graphing rational functions. Basically, a rational function is an equation of the form f(x) = p(x) / q(x), where p(x) and q(x) are polynomial functions, and q(x) /= 0. This seems pretty complex, but a rational function can be something as simple as C = 150/s.
Next up, Marine Biology. I learned about shallow subtidal communities. Good thing to know about them, they contain a lot of infaunal species, owing to the fact that the seafloor is blanketed with soft sediments.
Finally, English. We come to the conclusion of looking at ultimate reality in world religions, and frankly, thank god. I’ve been on the subject for a long time. So, what’s my conclusion? World religions on the topic of reality have very different views, a lot of which don’t work together. Some have absolute, all powerful gods. Some have limited, fallible gods. The nature of the world differs as well, with some interpretations saying that it was made, while others say it was transformed from some prior state of being.
It’s a very complicated issue, to say the least.
First order of business today was Algebra. I learned about adding and subtracting rational expressions. Basic summary of it, you need to find the least common multiple of both, and then work with that.
Next up, Sociology. I learned about leadership. Something I found pretty interesting from it was that there are two different types of leaders. The instrumental leader is the one that keeps the group focused, while the expressive leader is the one that keeps morale up.
Finally, Programming. I learned about BLE, or Bluetooth Low Energy. Basically, network technology meant to function more or less the same as Bluetooth, but consume less energy. Something interesting I learned was that a “mesh” effect was able to be done with BLE, where you could do a lot of stuff with one command. For example, turning all the lights off in a building with your phone.
First order of business today was Algebra. I learned about rational expressions. A ratio of two polynomial expressions such as (8+x) / (13+x) is called a rational expression. Because variables in algebra represent real numbers, operations with rational numbers and rational expressions are simple. In fact, to simplify a rational expression, you divide the numerator and denominator by their greatest common factor, just like how you simplify a normal fraction.
Next up, Sociology. I learned about group dynamics. Generally as a rule, the larger a group gets, the less intimacy the group has, but the more stable it is. In a two person group, if one person loses interest it falls apart. In a 100 person group, if a person loses interest then it’s not that big of a deal.
The size of a group can also affect attitude and behavior. Scientists have done experiments that showed that in larger groups, people are less likely to raise an alarm if a person has trouble. In smaller groups, people are far more likely to do so.
Finally, Programming. I learned about floating point numbers today. It’s basically a method of arithmetic that uses a formulaic representation of real numbers, trading precision for range. Put simply, it trades some of the accuracy for being able to display a lot more numbers.
