Perseid and Milky Way  by  TheBrockenInaGlory Summary:        The universal force in which holds a galaxy together is gravity. There are three main different type of galaxies, elliptical, spiral, and irregular galaxies. The galaxy in which Earth is in is the Milky Way which is a spiral galaxy. Stars in galaxies produce energy through nuclear fusion where hydrogen atoms fuse into helium atoms. In order to measure the distance between stars or other things in our galaxy we use light years which is the distance that light can travel in one year. However, when measuring things in our own solar system, we use astronomical units in which are equal to about 8.2 light minutes. In order for scientists to discover new planets, they use two main techniques, transit method and Doppler technique. Both of these techniques use stars to find planets rather than trying to look for the planets themselves. The Doppler technique uses the fact that as a planet orbits aro...

Solar lunar eclipse diagram  by  Tomruen Summary:        The positions of the Earth, Moon, and Sun heavily determine eclipses, seasons, and tides. For example, both types of eclipses are caused when the Earth, Moon, and Sun are aligned. Solar eclipses are caused  when the Moon is in front of, and blocking the Sun's light from reaching Earth. This results in not being able to see the Sun, or the Sun being partially blocked by the Moon. A lunar eclipse is caused when the Earth is in front of the Sun which blocks the light from reaching the Sun. Thus, turning the moon to a gray color or a dark red color depending on if the Moon is in the penumbra (gray) or umbra (dark red). Another example of how the positions of the Earth, Moon and Sun effect things is with tides. Spring tides (when the difference between the height of the high tides and low tides is very great), which have very high tides are caused when the Earth, Moon, and Sun are aligned in an...

nreed1005 Ms. Garcia Science 8 4/5/19 Digital is Better than Analog        “There's an ongoing flood of new LP releases (Amazon currently lists 938,000 LP titles ). Kings of Leon, Taylor Swift, Nine Inch Nails, and Kanye West all have their latest releases available on LP.” according to the article titled, “Why does analog sound better than digital,” by Steve Guttenberg. Digital is better than analog. Digital allows you to have a clearer sound that is controllable and can last forever. Most importantly, it is cheaper, which means that it can used by almost anyone. Analog is the past, we must invest in the future and use digital.        Using digital means having high quality sound that can be manipulated. “Digital has certain perfect things about it [, it] immediately solved all the problems of analog background noise, hiss, where pitch control all of those things.” according to the video titled, “Analog or Digital? (1993),” from Past...

Summary:        Analog technology is a representation or analogy of some type of measurement. Analog technology usually consists of a dial. Some examples of analog technology are a clock and speedometer. Most of the time, when speaking of analog technology, we usually just mean something that is not digital. Digital technology is when information (measurements) are converted to numbers/digits and the numbers are stored or displayed. Sampling is when splitting occurs in regular intervals to convert analog to digital form. Sampling converts continuous signal to discrete signal then reconstruction turns discrete signal back to a continuous signal. Although, this new continuous signal created by digital technology, is not as exact as the original. This is due to how the accuracy of analog signal is more than digital because digital signal is finite.

Instrument Project | Luke Pires, Nathaniel Marino, Nicolas Reed, and Oscar Ponce Summary:        For this project, we had to create a completely new musical instrument with a full scale. With that, we also had to answer questions about out instrument and its function, use a program to measure it sound waves and answer questions about them, and play a song on our instrument. What I learned about percussion instruments (which is the type of instrument that we made) is that in order to create different notes, each thing that you hit (in order case, wooden sticks) needs to be a different size. This is due to how different sizes means that there is a different amount of space that the sound wave can travel (and vibrate molecules) in each note. I also learned that different materials create different tones. For example, when hitting a piece of wood and metal with the same amount of force, the two will create different sounds due to the difference of tone. Lastl...

Glass.harmonica.in.rome.arp  by  Arpingstone Summary:        Music is created through the vibrations of molecules when sound waves hit them. In order to create different sounds and have a full scale, you must be hitting things with different measurements. For example, to test this, you can hold an object such as a ruler, and grab on to a part of it that is somewhat close to an edge. Then, hit the side of the ruler that is smallest, and then hit the other side of the ruler. You will then notice a difference. This is due to how the amount of space that the sound wave can travel is different when changing the size of the object in which you hit. This is the exact way that some instruments function. Instruments such as the xylophone or glass harp (the one where the cups are filled with water). For the xylophone, the bars (the things that you hit) are all different sizes. For the glass harp, each glass is filled with a different amount of water, which...
