Our method is strong because we took the time to go inside the library and measure each floor from the tile to the ceiling. We did not rely on our eyesight and did not just simply count bricks on the outside of the building. It is impossible to know the distance of the blocks above all the windows at the very top of the building just by looking at it. Other groups relied on this method and I think it makes it less accurate than ours.

What can you conclude about the relationship of musical notes to one another?

 

Musical notes are multiples of each other. Each note gets you a different harmonic, and it's because they are two times, three times, four times etc larger in frequency than the previous note. Just like with the standing waves we created, the piano notes all have a relation to previous notes in the form of a ratio between the different harmonics.

 

Some of the ratios in Table 3 are given special names in music theory. For example, the ratio C1 : C2 is called an octave and C3 : E3 is called a major 3rd. When two or more sound waves interfere with one another and create a pleasing sound, this is referred to as consonance. As discovered by Pythagoras, consonance occurs when the ratios of the two frequencies are small whole numbers, as you discovered completing Table 3.

Waves Lab 4

 

So far we have studied what a wave looks like, the 2 main types of waves, many features of waves, and how waves and sound are created by stringed instruments. In the previous lab, you saw how the guitar string creates what we call a “standing wave”. Stringed instruments can only create one type of standing wave which is called the fundamental, or 1st harmonic. This is because the string is fixed at both ends and a wave is only created when the string is struck (plucked in the case of the guitar). If, however, we fixed only one end and continually added energy, we would see different standing waves. You saw this in the last lab when you used the long spring to create the 2nd harmonic (a figure 8 shape). In this lab, we will observe the first 9 harmonics in order to see how they are related to the fundamental frequency of the string and musical notes.

Stoicism was actually quite different from Epicureanism. Stoics believed that strong emotions such as anger, love or passion would not happen to someone who was intellectually and morally perfect. Strong emotions cause a person's unhappiness, and that they are immune to misfortune. All that is sufficient for happiness is virtue. This is a really interesting philosophy, although they did not view it as a philosophy but more as a way of life. I do see the logic in it, because if you are not attached to anything emotionally then you really have no reason to be unhappy or to get upset.

Planarians are excellent models for human development and diseases as they have some similar genes to humans and are easily genetically manipulated. The proposed project for the University of Massachusetts Fall Semester of 2017 Writing in Biology Section class uses planarians to study cannibalistic behaviors. Large brown planarians would be studied under eight different conditions over the course of two weeks. Factors such as size of container, what kind of container, light exposure, feeding, and number of planarians in a container can be observed and controlled to view the planarian behavior. A control can be  several planarians in a moderately stress free environment, such as a dimly lit container. All eight groups would compare their collected data to this control. Specific behaviors can be quantitatively monitored and logged. It has been previously observed that there are also different ways in which the planarians will feed on other planarians. They can either fully surround and cover the planarian they are feeding on to hide it from other planarians, or there can be a group of planarians grouped around one planarian and all feed on it.

There is a deathly virus going around that is killing domestic dogs one by one. We have created vaccine that can save a pregnant mother and her babies and hopefully rebuild the population of domestic dogs. The mother we believe that we should save is a golden retriever. Golden Retrievers are known to be loving, and loyal family dogs. I know this to be true from personal experience. I had a golden retriever for 11 years. She was the cutest dog I have ever seen in my life. Every time someone came in the door whether it was my family or a stranger she would run right up wagging her tail and trying to lick them. Goldens are special dogs and even if you are feeling sad they are always there trying to make you happy. My dog also did this thing where she would sneeze and smile as soon as she saw you and it would always make me smile and laugh. Goldens are not just loving and loyal but they are also adventurous and love the outdoors. They love to go hiking, hunting and to play fetch. They also are really easy going and can get along with other domestic animals such as cats. When my family got our kitten my dog was five years old, and our kitten thought that our dog was his mother. My dog loved my cat and let him sleep with him. They loved each other and kept each other company. These are just a few of the reasons that this breed has to be saved. They are a perfect fit for any family, and they make such a good impact on everyone's lives that it enters. There has never been a case where someone has regretted bringing a Golden into their life. I promise that if we save this breed of dog that you will never regret it.

In the Hadley cell warm air can contain more moisture than dry air. Warm, humid air is also less dense than cold, dry air, therefore it rises. The air rises to poles since it is less dense and it gets much cooler.  As the air travels poleward at high altitude, the air pressure and temperature both decrease with elevation. As pressure decreases, air expands and the Sun then heats the Earth, the air rises which in turn creates this low pressure Hadley cell, which is just a continuous cycle.

Geo erosion discussion

Submitted by bmoreau on Thu, 10/26/2017 - 09:05

The process of beach erosion is natural, and so is coastal erosion. People look at coastal communities as prime real estate, so they get these seawalls built that slows down coastal erosion but it is also ruining the beaches. These walls do not allow for the sand from coastal erosion to be taken in from the waves and moved to the beaches, so as it may be a short term solution to part of coastal erosion it on the other hand is causing beaches to erode. There has been some engineering of different kinds of seawalls that allow the waves to crash in and out more naturally instead of just smacking the walls but this too does not help much. We humans also dam many rivers that would lead to the ocean. This is also an issue because our ocean and beaches need this exchange of sediments to be transferred to our beaches. We get a lot of our sediments from these rivers and by damming them up, we are theoretically starving the ocean, and ruining our beaches. The main problem is that humans are interferring with the natural processes of the ocean, and the best thing we could do is just leave it alone, and to not build walls, or dam up rivers, because there are only bad long term effects.

Geo wave refraction

Submitted by bmoreau on Wed, 10/25/2017 - 12:24

Wave refraction causes the waves to bend as it enters shallower waters. This bending happens because the part of the wave in shallow water piles up and the deeper water part of the wave is forced to slow down which causes the pile up on the shallow part, and the shallow part bends into the headlands as shown in the figure. Wave refraction causes focused energy to hit the headlands, once they hit the headlands it causes dispersed energy in the bays between the headlands, So the erosion from the focused energy flows into the lesser energy area of the bays, where the sand from the headlands are now being moved to the bays which causes the deposition of sediment shown in the figure.
