    1. Thus a 10-year-old child who does as well as the average 10-year-old child has an IQ of 100 (10 ÷ 10 × 100), whereas an 8-year-old child who does as well as the average 10-year-old child would have an IQ of 125 (10 ÷ 8 × 100)

      example of intelligence quotient equation

    2. standardization of a test involves giving it to a large number of people at different ages and computing the average score on the test at each age level.

      does this account for kid's different abilities?

    1. autistic savants, people who score low on intelligence tests overall but who nevertheless may have exceptional skills in a given domain, such as math, music, art, or in being able to recite statistics in a given sport
    2. triarchic model, practical intelligence, refers primarily to intelligence that cannot be gained from books or formal learning

      would this be also known as "streets smarts"

    1. 0.5 g ammonium carbonate

      Used to make basic solution, part of the complex solution to form a high enough pH solution for Luminol to oxidize, but not high enough so that Copper does not dissolve. The Ammonium carbonate ensures that the pH remains stable.

    2. 4.0 g sodium carbonate

      Used to make basic solution, part of the complex solution to form a high enough pH solution for Luminol to oxidize, but not high enough so that Copper does not dissolve.

    3. 24.0 g sodium bicarbonate (baking soda)

      Used to make basic solution, part of the complex solution to form a high enough pH solution for Luminol to oxidize, but not high enough so that Copper does not dissolve.

    1. Theory of mind refers to the ability to think about other people’s thoughts. This mental mind reading helps humans to understand and predict the reactions of others, thus playing a crucial role in social development.
    2. Theory-Theory is the tendency of children to generate theories to explain everything they encounter. This concept implies that humans are naturally inclined to find reasons and generate explanations for why things occur.

    1. ___________________________________________________________________________

      I will have less stress at the end of this semester after I pass the classes that I'm taking. Being able to have a home life and not just work and school ever night of the week is going to help me and my relationship with the wife and my children.

    2. __________________________________________________________________

      try not to let the little things bother me and stay focused on what I need to do

    1. clustering rehearsal, the person rehearses previous material while adding in additional information. If a list of words is read out loud to you, you are likely to rehearse each word as you hear it along with any previous words you were given
    2. Executive function (EF) refers to self-regulatory processes, such as the ability to inhibit a behavior or cognitive flexibility, that enable adaptive responses to new situations or to reach a specific goal.
    3. working memory. Working memory is the component of memory in which current conscious mental activity occurs. Working memory often requires conscious effort and adequate use of attention to function effectively
    4. Sensory memory (also called the sensory register) is the first stage of the memory system, and it stores sensory input in its raw form for a very brief duration; essentially long enough for the brain to register and start processing the information
    1. (−3e−2x+2)+3(e−2x+2x+3).

      This equation is not correct since if dy/dx is inserted on the differential equation dy/dx+3y=6x+11 it should be: ((-3e^-2x)+2)+3((e^-3x)+2x+3)=6x+11 Correct?

    1. Solution This reaction is an alpha decay. We can solve this problem one of two ways: Solution 1: When an atom gives off an alpha particle, its atomic number drops by 2 and its mass number drops by 4, leaving: Po84206Po84206\ce{_{84}^{206}Po}. We know the symbol is PoPo\ce{Po}, for polonium, because this is the element with 84 protons on the periodic table. Solution 2: Remember that the mass numbers on each side must total up to the same amount. The same is true of the atomic numbers. Mass numbers: 210=4+?210=4+?210 = 4 + ? Atomic numbers: 86=2+?86=2+?86 = 2 + ? We are left with Po84206Po84206\ce{_{84}^{206}Po}.

    1. __________________________________________________________________

      The problem is that he does not have a plan. He needs to figure out what if a four year degree is what he needs to have for his career or if he can just take a couple of classes. He also needs to figure out if he wants to start a family.

    2. __________________________________________________________________

      core issue is both of them work. The other issues is that he wants to start having kids which takes an extreme amount of time raising them. He needs to figure out if he wants to tackle a four year degree.

    1. Vice President Lyndon Johnson took the oath of office while the widowed Jackie Kennedy stood in the background, still wearing a dress that bore the stains of her late husband’s blood.

      Never understood why she didn't change beforehand and questioned why she needed to be there next to him.

    2. Conspiracy theories spread rapidly in living rooms across the nation as reports about the accused assassin Lee Harvey Oswald circulated.

      I find it interesting that this is still a common and popular conspiracy theory. It puts into perspective that people believe in conspiracy theories when they are scared of the uncertainty and confusion.

    1. Is very interesting to know that Piaget stages are similar to the Montessori method like for example : “ practical life” and “ sensory area “ are designated to potential fine motor skills , grosor skills and cognitive development in which consists that the child can manipulate or build blocks or transport objects to another tray . Sounds pretty simple but everything had a purpose .

    1. knows the precise momentum of the particle, it is impossible to know the precise position, and vice versa. This relationship also applies to energy and time, in that one cannot measure the precise energy of a system in a finite amount of time. Uncertainties in the products of “conjugate pairs” (momentum/position) and (energy/time) were defined by Heisenberg as having a minimum value corresponding to Planck’s constant divided by 4π4π4\pi.

      Very important!!!!!!!

    1. Lack of ownership of a television set is also a way to preserve innocence, and keep the exposure towards anything inappropriate at bay. From simply watching a movie, I have seen things I shouldn’t have, no matter how fast I switch the channel. Television shows not only display physical indecency, but also verbal. Many times movies do voice-overs of profane words, but they also leave a few words uncensored. Seeing how all ages can flip through and see or hear such things make t.v. toxic for the mind, and without it I wouldn’t have to worry about what I may accidentally see or hear.

      "only me" its best if I just write it out and once I'm done I can go back and fix the paragraph or rewrite sentences

    1. Scholars and reporters have noted the democratizing effect of new media, meaning that new media help distribute power to the people through their personal and social characteristics. Many media scholars have commented on these changes as a positive and more active and participative alternative to passive media consumption

      I like this part of the internet, where people openly discuss new technology and are able to weigh the pros and cons, due to experts chiming in and a social "hive mind" coming into play of "Oh, AI is bad" because people heard about it stealing art, rather than having a critical take on how AI performs these tasks and how it creates elements from pictures. In short, the people are bad, the technology may not be; we just might not be ready for it.

    1. Personal computers allowed amateurs and hobbyists to create new computer programs that they could circulate on discs or perhaps through early Internet connections.

      I think this was a particularly nostalgic time for myself and lots of people. Receiving a custom-coded game from a friend is much more personal and enjoyable than downloading one off the internet. I believe a lot of personal connection has been and will be lost the further technology progresses. However, there is an argument to be made for human spirit and needing to socialize as a social creature.

    1. It remains to be seen whether or not minority-owned media outlets will produce or carry more diverse programming, but it is important to note that the deregulation over the past few decades has led to a decrease in the number of owners of media outlets who come from minority groups.

      This is another reason why I dislike the current economical situation in America. Too much of it is controlled by a select few, and this somewhat proves that. I think diversity should be a paramount part of television, but only if its aimed at adults. There can be a dangerous push to move people, particularly children, into minority groups, and I believe that benefits those in power.

    1. Just as a farmer plants seeds that he or she then cultivates over time to produce a crop, the media plants seeds in our minds and then cultivates them until they grow into our shared social reality.

      This is a very grim proposition. I remember watching a documentary on the emerging cyborgs; People with non-organic parts implanted into their bodies. It talked about how technology inherently favors those in power, and how reliance on technology to survive, such as a prosthetic arm, could be catastrophic. Knowing a mental form of this exists is scary.

    2. We all use the media to escape our day-to-day lives, to distract us from our upcoming exam, or to help us relax. When we are being distracted, amused, or relaxed, the media is performing the diversion function.

      I personally engage in this function of mass media the most, I believe. I play video games to relax, so that is a function of diversion mass media. There can also be other functions of mass media in video games, as acceptable norms and social themes can be explored, challenged, and broken in them.

    1. With this, the “print age” began, which extended from 1450 to 1850 and marked the birth and rise of the first mass medium

      Its strange to think of the books created by the printing press as being a form of mass media, but it makes sense. The repeated dissemination of knowledge is what make mass media a thing, and books are no different. The same information that is repeated by news outlets is the same kind of stuff that would be mass produced back then.

    1. So what causes the shell structure? In atoms it is the Coulomb force of the heavy nucleus that forces the electrons to occupy certain orbitals. This can be seen as an external agent. In nuclei no such external force exits, so we have to find a different mechanism.

      Ok. In my leapfrog study of Chemistry over the last 40+ years, we didn't cover this in high school chemistry. I have often puzzled about orbitals but never asked about the mechanism which caused them. Now I am fresh with questions which brought me to the previous answer to my previous question, "how does a reduction of neutrons make an isotope more unstable?" I could understand more neutrons making the isotope radioactive (but I really don't). I was annotating my new Periodic Table of the Elements with group numbers, trends, and electron shell counts (not orbitals). I noticed that Uranium had an isotope with an atomic mass which was less than 238 and it was radioactive. I didn't understand how that could be. This morning I asked the question and it took me to Stable_and_Unstable_Isotopes in another course. When I looked for it again, I was in Allied Health. When I read further, I saw the reference to Quantum Physics of which my wife and I are interested. (We have an enlarged photo of the 1929 Solvay Conference over our piano in the family room.) Peace.

    1. The water (or other equivalent reaction partner) is an important contributor to the energy calculus. In ATP, for instance, simply "breaking" a phosphoanhydride bond - say with imaginary molecular tweezers - by pulling off a phosphate would not be energetically favorable. We must therefore be careful not to say that breaking bonds in ATP is energetically favorable or that it "releases energy". Rather, we should be more specific, noting that the hydrolysis of the bond is energetically favorable.

      An interesting example of how situational and context driven chemical and biological mechanisms can be. Isn't it unique and strange that the favorable mechanism here is strictly hydrolysis, which requires water, the most plentiful molecule in living things?

    2. A phospholipid is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone.

      I also recognize that the unsaturated carbons forming a double bond are the reason for the bent shape in the second fatty acid since the bond angle changes between H3C-CH3 and H2C=CH2

    3. Stearic acid is a common saturated fatty acid; oleic acid and linolenic acid are common unsaturated fatty acids. Attribution: Marc T. Facciotti (own work)

      I guess "saturated" in this case is regarding the carbon atoms' saturation with bonds to hydrogen since the unsaturated fatty acids have double bonds and therefore less than the maximum electron domains for carbon

    1. Because here’s something else that’s weird but true: in the day-to-day trenches of adult life, there is actually no such thing as atheism. There is no such thing as not worshipping. Everybody worships. The only choice we get is what to worship.” In David Foster Wallace’s commencement speech at Kenyon College, he says that the real purpose of education isn’t to instill us with the capacity to think—something we all possess—but rather, to help us maintain constant awareness that we have the choice of what to think about. Have you ever thought about yourself as having a choice over what you think about? Or, do you feel that you do not have a choice in what to think about or pay attention to?

      what worship define as people decide what they want for themselves and for others and their opinion.

    2. This, I submit, is the freedom of a real education, of learning how to be well-adjusted. You get to consciously decide what has meaning and what doesn’t. You get to decide what to worship.

      Talking the word worship what it means to him.

      Why don't these work??? Give them functionality please.

    2. Answer When we choose the most negative entry in the bottom row, we are trying to increase the value of the objective function by bringing in the variable x1x1x_1. But we cannot choose any value for x1x1x_1. Can we let x1=100x1=100x_1 = 100? Definitely not! That is because Niki never wants to work for more than 12 hours at both jobs combined: x1+x2≤12x1+x2≤12x_1 + x_2 ≤ 12. Can we let x1=12x1=12x_1 = 12? Again, the answer is no because the preparation time for Job I is two times the time spent on the job. Since Niki never wants to spend more than 16 hours for preparation, the maximum time she can work is 16 ÷ 2 = 8. Now you see the purpose of computing the quotients; using the quotients to identify the pivot element guarantees that we do not violate the constraints.

    1. 100tan(42∘)=atan(20∘)100tan(42∘)=atan(20∘)100 \text{tan} (42^{\circ}) = a\text{tan} (20^{\circ})\nonumber tan(42∘)tan(20∘)=a

      What happens to the 100'? It reappears below.

    1. Language can also have an impact on how we feel about this reality. How we define words and how we feel about those words is highly subjective. In fact, cognitive psychologist Lera Boroditsky showed a key to a group of Spanish- speakers and to a group of German- speakers. The researchers then asked the participants to describe the key they had been shown. Because the Spanish word for “key” is gendered as feminine, Spanish speakers defined the key using words such as lovely, tiny, and magic. The German word for “key” is gendered masculine, however, and German speakers defined the key using adjectives like hard, jagged, and awkward (2003). This study suggests that the words we use to define something can have an impact on how we perceive what those words represent.

      People's primary language can affect how they see the world. This highlighed portion uses Spanish speakers and German speakers as an example. The two different groups were asked to describe a key, and the Spanish speakers used words more often associated with femininity like "lovely" and "magic" , likely because the word key is gendered feminine in Spanish. The German speakers were more likely to use adjectives like "hard", "jagged", and "awkward" and the word is gendered "masculine" in German.

    1. Ill-structured problems are often poorly defined and usually do not include all of the information required to solve them. There may be multiple ways of solving them, and even multiple possible “correct” outcomes/answers.

      Mentally, I understood that this was true, but this sentence just really made me have a new appreciation for this. We're always doing problems which are similar to real world solutions, but they aren't real. Like how correlation doesn't equal causation. I still had a bias that A is affected by B so C. In the real world though, that's just not true. Like the old meme, I added below. People just think differently, and neither is exactly wrong.

    2. Identify the important vocabulary words and key concepts presented in lecture. Be able to recall this information

      Personally, I have an easier time learning the concepts, so I struggle with the specific definitions. For almost every vocabulary word, I have something to help me remember it. One of the most obvious ones is meiosis and mitosis. I like the silly example of my-toe-sis is what your toe cells use and ME-iosis is what made me. Or for anion and cation. Cats are pawsitive. Anions are A-Negative-ion.

    3. it is surprisingly rare to find problem solving taught explicitly in formal educational settings

      I understand why it can be difficult to teach problem solving skills while also teaching specific material. However, I'm curious if anyone has specific ideas about how to use teach both at the same time?

    4. We will make frequent use of the pedagogical tool we call the “Design Challenge” to help structure our discussion of the topics we cover in class.

      Is this on the syllabus?

    5. t is nevertheless important for you to attempt to make a contribution to the discussion. Examples of other meaningful contributions might include: asking for clarification; associating the question with another class topic (trying to make connections); and expressing what you are comfortable with and what confuses you about the question. Don't be afraid to say "I don't know". That's perfectly okay and even expected sometimes. Be prepared for the instructor to follow up with a different question, however, that will try to either highlight something that you likely do know or to ask for your help with identifying a point of confusion.

      I'm relieved to read this because I feel anxious when called on while not knowing the answer when most students know.

    6. Some in-class questions will ask students to formulate questions themselves. This exercise forces the student to reflect on and try to articulating the key point of the lesson. These critical exercises should engage you to think more deeply about a topic and to place it in the broader context of the course.

      I think this would be a great and difficult exercise for me as I had mentioned that when I need help I'm afraid to ask because I don't know what to ask if that makes sense? I just know that I'm not understanding and maybe this exercise will help me practice on how to ask questions..

    7. ost-study guide.

      Having a pre and post-study guide for the class is new to me and I feel it may help me gain a better understanding of the lecture. As one of my peers mentioned I've only reviewed a study guide for an exam. When I looked at the first pre-study guide I was confused and I wanted to ask for help but I was not sure how to ask for help.

    1. The Design Challenge

      The Design challenge is used to help us students better understand the material and unlike the scientific method, it helps us create explanations for questions or drawbacks.

    2. This teaching tool helps us: • develop a frame of mind or way of approaching the material and • design a set of sequential steps that help structure thinking about course topics in a problem-solving context.

      What the design challenge is. I had a comment about this in the first reading and now my question from that reading has been answered.

    1. The slightly positive (δ+) charge will develop on the less electronegative atom, as electrons get pulled more towards the slightly more electronegative atom. A slightly negative (δ–) charge will develop on the more electronegative atom. Since there are two poles (the positive and negative poles), the bond is said to possess a dipole.

      So dipoles are only present when there's a slightly positive charge and a slightly negative charge? Not present in nonpolar bonds then?

    2. Given that we know an electron transfer will take place between these two elements, we can conclude that differences in electronegativities of ~2.2 are large enough to cause an electron to transfer between two atoms and that interactions between such elements are likely through ionic bonds.

      Can Ionic bonds be covalent? Or do they just have characteristics of a covalent bond?

    3. These types of interactions derive their name from the involvement of pi bonds, a specific type of covalent bond between two atoms in which neighboring electron orbitals are close enough to overlap. We’ll leave the underlying discussion of molecular orbital theory for your chemistry course and just say that we usually associate pi bonds with double or triple covalent bonds. In biology, these types of bonds occur in many kinds of molecules, particularly those with so called conjugated pi systems including aromatic ring structures like those seen in some amino acids, vitamins and cofactors, and nucleic acids.

      I'm not quite understanding pi interactions. Is this saying that pi bonds are only seen in double or triple-covalent bonds? I'm not understanding how you would tell if there's a pi interaction.

    1. t’s a 5-minute scene. By my count, there are 5 setups, one master, two medium shots and two close ups. Fincher cheated a bit by using two cameras which cut down on the number of times they needed to move the camera, but they still took 2 days to shoot that scene in 99 takes. That means Jesse Eisenberg and Rooney Mara did the whole scene 99 times in row over two days to get it right. Exhausting

      Wow. a 5 minute clip took 2 days to shoot! I didn't realise how long they took.

    2. Let’s start with the most basic obstacle that everyone on a film set must confront and somehow overcome: time. There usually isn’t very much of it. Not only does it take a long time to set up, execute and dismantle every shot for every scene and sequence, the overall schedule is hemmed in by the competing schedules of other productions running long or needing to start on time tying up the cast and crew. The most immediate impact this time crunch has on actors is an extremely limited time for rehearsals. In live theater, actors might have 4 to 6 weeks to rehearse their roles. In cinema, they’re lucky if they get a day or two. Often that means “rehearsals” are really just the first few takes of every shot, working out how to deliver the lines, how to move in the space (known as blocking), how to play off the other actors.

      If cinema actors barley have a day or two to rehearse,then why do they take forever to release the film?
