Superconductors are used for all these applications and are very  important in everyday life.

 
I want to throw out some different applications that we use every  day such as high-speed computer chips, radio frequency amplifiers,  magnetic resonance, and wireless transmitting antennas just to name a  few. Superconductors are used for all these applications and are very  important in everyday life. A superconductor is defined as a substance  that offers no resistance to the electric current when it becomes colder  than a critical temperature. Studies show that the temperatures need to  be between absolute zero and 10 Kelvin for materials to act as a  semiconductor.  In the medical field, the superconducting magnet is said  to be the most expensive component of an MRI system. I looked at this  discussion when it was assigned, and I didn’t understand the concept of  superconductivity, but as I read and continue to understand it more, I  really I’m really excited to learn more about it.

Superconductors allow electricity to be conducted with little to no  resistance. One use of super conductors that is especially interesting  to me is that in certain areas of Japan and Germany they have  experimental magnetic levitation trains. These trains can travel at  higher speeds, are more efficient, and are environmentally friendly.  These trains use superconducting magnets to lift them above the rails  and almost eliminate friction. This makes me wonder about the potential  to tie this technology into cars, which would be beneficial but would  require a lot of work, just a thought that popped into my head while  reading about this. 
Other uses of superconductors are they have been used experimentally  to speed up connections between computer chips, superconducting coils  are used in MRI machines, and some high energy practical accelerators.

To explore the law of refraction.

 As light travels from one medium to another, the path the light  travels bends in a predictable fashion. This optical phenomena is known  as refraction. The law of refraction can be used to determine the angle  of refraction when the index of refraction is known for both mediums.   The law of refraction is an important physical law with applications in  the field of optics.  The law of refraction is known as Snell’s Law,  named for Willobrord Snell, who discovered the law in 1621.

N.d. 

 
I will be discussing the use of ultrasonic nondestructive testing by  the military. “Defending the national interest requires the use of  sophisticated artillery, technologies and equipment. These defense  systems are subject to a high degree of stress whether they are missile  systems, or the jets and naval vessels that launch those systems. A flaw  or weak spot caused by corrosion or wear can cause a critical component  to fail and damage a serious investment. Nondestructive testing (NDT)  for the military and defense industry is an indispensable part of  fielding and maintaining these systems. Nondestructive testing for the  military is widespread and essential. It ranges from relatively  straightforward NDT such as ultrasonic testing of welds aboard naval  vessels to the testing of complex aerospace components that combine  metals and composite materials. In either case, the safety of the  sailors, soldiers, marines, and airmen who operate these systems depends  on regularly performed military NDT” (Nondestructive Testing for the  Military). 
      According to Military Nondestructive Testing,  various methods of nondestructive testing—ultrasonic, eddy current,  magnetic particle, radiographic, liquid penetrant, laser testing, and  leak testing—allow military personnel to inspect infrastructure,  vessels, vehicles, and weapons systems for flaws, corrosion, and other  defects which could lead to failure and endanger the lives of servicemen  and servicewomen (Safety Precautions). 
     Ultrasonic  nondestructive testing (NDT) is a method used to characterize the  internal volumes of materials. It works by propagating high-frequency  sound waves well above the range of human hearing throughout the  material. It can be used to detect flaws and discontinuities in metals,  composites, and other materials. “High-frequency sounds travel through a  uniform medium until they reach a discontinuity that reflects them  back—such as air or fluid at the other side of the material—or  incongruity in the matrix of the material. These reflected waves can be  resolved into visual images that allow an ultrasonic testing technician  to see flaws in the material, determine if corrosion is present, or  detect corrosion eroding the thickness of the material. Ultrasonic  testing works well for contiguous materials like metals, but not as well  for materials where discontinuities are part of their normal makeup  like wood, wood composites, or paper materials” (A Comprehensive Guide).
      Some types of ultrasonic nondestructive testing are: Straight Beam,  Angle Beam, Immersion Testing, Phased Array, Time of Flight Diffraction,  Total Focusing Method (TFM), and Guided Waves. (Please visit  https://www.zetec.com/resources/ultrasonic-testing-overview/ for a full  description of how each of these testing is done.

The use of ultrasound for non-medical purposes is more common that I  thought.  It is used for many applications not limited to aerospace,  automotive, construction, manufacturing, environmental protection,  purification of water, decontamination of the atmosphere and soil, and  several other remediation applications. There is a study of the effects  of ultrasound on materials. This is known as sonochemistry.
To find more applications it is easier to research Nondestructive  Testing (ultrasonic) and you will find companies that specialize in the  use of ultrasonic testing for finding the thickness and faults including  corrosion in pipe. It is a non-destructive method using several methods  but primarily pulse-echo through transmission from something that emits  the sound wave and something to receive it (probe). This can very  accurately find faults in the material in a noninvasive way. Say you  have a large steam line in a factory and are unsure of the damage of  oxidization that has occurred in the lines, it would be easier and maybe  more cost effective to hire a company to evaluate before disassembling  and planning on re-piping if unneeded. I only think of this application  because I currently work in an older manufacturing plant, and we have  some steam piping in use that we really have no way of knowing its  density and integrity without shutting down the system and taking it  apart and reassembling. We often must plan for the worse and have parts  on hand and it can be unnecessary. Once again, I am finding these fields  of study fascinating. I hope you all are enjoying your research!

  Silicon is the most abutment element in the earth’s crust and is molten at abo

 
Silicon is the most abutment element in the earth’s crust and is molten at about 1400c where salts melt at 800c. Molten  silicon thermal energy storage offer higher storage temperatures than  that of salts. ‘Silicon has unique properties that confer the ability to  store more than 1 MWh of energy in a cubic meter, ten times more than  using salts.’  A research that has been done by MIT ‘ says that if you  use two 10 meter high storage tanks of molten silicon you would be able  to power 100000 households. In addition the silicon can hold up to 100  times more energy per unit than conventional solar.

Molten salts are used in heat transfers fluid and thermal energy  storage in solar power plants.  This is solar power collected through  mirrors and lenses that are laid out or set up in high sun light  concentrated areas. Molten salts are stored into hot storage tanks where  it can be kept for several days and then when it is needed it will be  turned into electricity. The salts are stored at temps around 565 c and  then once they are cooled to 290c it will be moved around for further  cold storage and reuse.

  Molten salt thermal energy storage systems  are used during times when energy

 
Molten salt thermal energy storage systems  are used during times when energy is not needed. The liquid salt is  stored as thermal energy in highly insulated tanks at a temperature of  300-500 degrees Celsius, depending on the type of salt being stored.  These systems most commonly utilize sodium nitrate and/or potassium  nitrate due to their non-corrosive nature.  
When energy is needed, the salt is pumped  into a steam generator where the hot salt boils water. The steam  produced from the boiling water turns a turbine generator, which  produces energy. After the salt cools, it is pumped back into the  storage system where it is reheated to prepare for another use (Dodaro,  2015). 
In my opinion, using molten salt as a form  of alternative energy production/storage seems like a good option if we  can create more plants. Right now, there are very few molten salt  plants; therefore, the process does not create much energy. “The largest  molten salt solar plant, located in United States, can produce 110  Megawatt of electricity. While the largest solar power plant can produce  more than 2,000 Megawatt of energy, almost a third of the largest coal  power plant with 6,720 Megawatt” (sataksig, 2020). Molten nitrate salt  has a volumetric heat capacity of around 3,000 
. That is roughly 1,000 
more than similar synthetic heat transfer processes.  
In addition, these salts do not pose  hardly any hazard to the plant they are in or the surrounding areas. The  only precaution that must be taken is to keep the salt away from open  flames, sparks, or any sources of ignition as the salt will release  oxygen when they break down, providing more fuel for a fire (McMullen,  2016).

Scenario
Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of Rome. It had been a long flight from New York to Rome, but as she stretched, and her bones creaked as though she was old, she knew that in fact, she was a tiny bit younger than her compatriots back home, thanks to traveling at hundreds of miles per hour. In fact, time for her was running slowly compared to her friends in New York for two reasons: the speed at which she had traveled and the height of the airplane above the Earth. Neither, though, were noticeable.
