Philosophy Essay: Against Representation

Throughout much of our study and development of human cognition and its replication in the various forms of artificial intelligence, there has been an underlying assumption from which we have based our work...

I was recently assigned to read this entire article/essay/magazine in a class of mine and was blown away by how comprehensive it is. If you guys are just beginning to dip your toes into IT or software development, then this is a must-read! To read: https://www.bloomberg.com/graphics/2015-paul-ford-what-is-code/

Symbolic Logic: Conditional/Indirect Proofs and Proving Theorems

Hey guys! So, this time, we're going look at other methods we can use to construct proofs when just deriving from the premises isn't enough. Conditional Proof (CP) The setup: Basically, you use this method when the conclusion or a part of the conclusion you want is a conditional. This makes it so you assume…

How To Read/Trace Recursive Methods

So, recursion, one of the hardest units in APCS. The concept is pretty easy but the execution is a bit trickier. Today, I'm going to pass on a trick that my teacher taught me on how to trace your way through a recursion problem. I'm going to assume that y'all already know what recursion is…

Our Sunken Place |July Study Piece Part 1: The Psychology

“What good fortune for governments that people do not think.” - Adolf Hitler   In humans, there has always been an intrinsic struggle between the self and others. We must be able to maintain a distinct self-identity while at the same time be able to fit as one of the innumerous cogs of society. Because…

APCS Chapter 6: 2D Arrays and ArrayLists

Alright, it's time to tackle 2D arrays and arrayLists. 2D arrays are basically arrays of arrays. First off, 2D arrays: 2D Arrays To start off with, the declaration and instantiation. Since 2D arrays are objects, we will use the new operator. There are several ways to do this: The "normal" way:data type [] [] name = new data type…

APCS Ch 6: Sorting and Searching Methods

Sorting methods as it pertains to arrays isn't the simplest thing to wrap your head around but the concept and the way they should work should be pretty intuitive. You would need to know about two main sorting methods in APCS; the selection sort and the insertion sort. Like the different types of loops, both of these…

APCS Ch 6: Arrays Basics

Arrays are basically lists of things. This list can contain both objects and primitive data. The basic array can be declared and instantiated as such: (data type)[ ] (arrayname) = new (data type) [(number of elements)]; Since arrays are considered as objects, the declaration and instantiation follow the pattern of other objects. So, if I…

AP Com Sci Chapter 2 Lab Review

This lab review goes over three labs within Chapter 2: the base conversion lab, the circle lab and the string manipulation lab. Even if you aren't an AP Comp Sci student, if you are learning Java and want some practice, these lab reviews are a good resource. Chapter 2 covers the concept of objects and primitive data.

Different mathematical theories and formulas weren't invented in a vacuum; each theory and formula was made to solve a problem. So, when learning about math, you shouldn't learn it in a vacuum either.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I've found it!), but 'That's funny...' -Isaac Asimov

Full Experimental Design for Testing Cognitive Ability Through Temperature Control

*This Experimental Design was a project for an AP Psych class so it's not representative of what a real experimental design looks like. This design also ties into a previous article on the site that goes over tbe subject of the study a little less formally. This design was based off of said article, actually.…

Can we use the excess CO2 on Earth into fizzy drinks? I think that the CO2 in soda is from power plants and factories and that sort of thing but can we harness this greenhouse gas from other places? For example, with car exhaust and the like. Even if that's not helping the emissions problem, it's like a self-perpetuating debt; the payment just keeps getting delayed. With so much soda being consumed every day, there are plenty of places to put CO2 in without releasing it directly into the air. Just a thought. 

On the Soapbox: Hurricane Season

This isn't the best time for a "I told you so" in regards to the recent hurricanes in the Caribbean and the ones coming up along the US's southern coast. However, it is also the best time before people start blaming lesbians and gays for God's supposed wrath. In fact, they've already started so I might as well.
