Determining a good balance between a rising economy, the need for environmental protection and social responsibilities in order to provide a good life for the current and future generation is what is energy sustainability. In other words, it is meeting the needs of the current generation without compromising the future needs. In this day and age where the energy demands are rapidly increasing, renewable/sustainable energy technologies׳ adoption is the way to go. Sustainable energy is the need for today not...

The idea behind quantum computing is to resolve problems in various domains of mathematics, physics, chemistry etc. They are mainly deployed to perform operations that are super complex in nature and are beyond the computing of conventional computers. They basically work with the technology of qubits in which the control signals are operated upon. The qubits are represented using Bloch sphere, in which any point denotes a combination of qubits. The functionality of qubits depends upon two states spin-up and...

This pendulum labâs objective is to describe how the back-and-forth motion of a pendulum can be changed through measuring the properties of a pendulum, as well as determine which properties of a pendulum affects its period. Groups of generally four students created their own pendulum, all materials provided in the classroom, and each group tested how three different properties affect the period of the pendulum, which includes the amplitude, the mass, and the string length. While testing these different things,...

Friction is, by definition, the resistance to motion. The magnitude of this resistance is a function of the materials, geometries and surface features of the bodies in contact, as well as the operating conditions and environment. It is often desirable to minimize friction to order to maximize the efficiency of a component or process. Generally speaking, friction increases with load and surface roughness and can be decreased by the use of a lubricant. Friction is the tangential resistance to motion...

In this experiment, our aim is to determine the unknown tension by using the components of the force vectors in equilibrium. Method First, we place a ring with three strings over the center (reference point), and set up the three pulleys. We will have two known masses which are 50 g each hanged from two strings which can be changed by applying different masses, and moving the direction of the force. In addition, the third pulley will help the system...

Generally, the density functional theory has been utilized progressively in the number of areas of chemistry and materials sciences to account for and indicating the attributes for complicated scenarios at an atomic level. More calculatedly, DFT in form of data processing approach has been studied by checking the formulations and progression entities. These systems have the laboratory results that are overburdened with inappropriate outcomes and unsteady ambience. The current density functional theory application includes the working on the interpretation of...

Atomic force microscopy (AFM) has advanced to be one in every of the foremost powerful tools for the characterization of material surfaces particularly on the nanoscale. It is a vital Nano instrument technique for several applications such as cell biology and nanoelectronics metrology and inspection. The utilization of a single AFM instrument is understood for its very low speed and not appropriate for scanning massive areas, leading to very-low-throughput measurement. Parallelizing AFM instruments will be presented to overcome those challenges....

Human beings have been trying to understand how light works since the time of the Ancient Greeks. In roughly 300 BC Euclid studied the properties of light, he thought light travelled in straight lines and described the laws of reflection. In 1690 Sir Isaac Newton came out with the corpuscular theory of light, he believed that light was shot out of a source in small particles. Also, in the 17th century the Dutch astronomer Huygens suggested a wave theory of...

There is this unpopular opinion that everything is unique. Even the things we think are the most alike, still have some sort of variation in them. Take identical twins for instance; science made us to understand that there is no identical twin that are 100% the same. That is talking about their DNA compositions. The keyword here is âdifferenceâ. What is the difference between a ball and a box? First of all, they are not of the same shape. They...

Physics is the study of how the universe works, it lays the foundation for the description of the cause and effect objects have on one another. The consequences forces have upon impact with objects lay the foundation for the interaction of forces in the physical world. Forces are vector quantities they carry a magnitude as well as a direction, when forces balance each other out they are said to be in equilibrium meaning the vector sum of these forces add...

In this essay, I will present the key scientists who studied the atomic theory and their contributions to science. Democritus Democritus lived in 5th century B.C. in Greece. âDemocritus knew that if a stone was divided in half, the two halves would have essentially the same properties as the whole. Therefore, he reasoned that if the stone were to be continually cut into smaller and smaller pieces then, at some point, there would be a piece which would be so...

In 1909, Ernest Rutherford discovered that the bulk of the atomic magnitude was tightly condensed into a nucleus, which was establish to be positively charged. It became clear from his assay in 1911 that the coveted pudding example may possibly not account for atomic structure. In 1913 as Rutherford's post-doctoral student, Neilâs Bohr planned a new form of the atom, in which electrons orbited the center with classical periods, but were barely allowed to give discrete principles of raw-boned momentum,...

Sir Isaac Newton was an English physician from the 17th century, and he is renowned throughout the modern world for the 3 laws of motion that he created. These have been accepted in modern society as factual information, due to modern research, even though he was born in 1642. Throughout his life he created his 3 laws. His first Law states âthat an object at rest but an object with motion would keep at the same speed unless acted upon...

Blue light is a spectrum of light that can be seen by humansâ eyes. Blue light produces a high amount of energy due to its short wavelength of 400-450 nm. Phones, computers and other electronic products with screen emit blue light and ever since phones became mainstream more people have started using their devices longer with many people having the habit of checking their phones at night. This may seem like a harmless habit but this could be harmful to...

The purpose of the density of liquids experiment was to learn the techniques on how to measure and dispense liquids with a graduated pipet and a buret while applying the concepts of accuracy, precision, random error, and systematic error. When calculating the densities of the known and unknown NaCl solutions, both mass and volume were measured by the difference and error of each measurement with error propagation was calculated. Once I learned how to use the graduated pipet, buret, and...

The following claim âWhat are the processes that drive Earth towards non-equilibrium,â can be deconstructed into two key elements: How did Earthâs thermodynamic system evolve away from thermal equilibrium? And what processes drive it towards non-equilibrium? The present-day Earth system is notably unique when contrasted to its planetary neighbours. This uniqueness, in areas such as global cycling is result of an exclusive atmosphere that is far from thermal equilibrium. The atmospheric system encompasses a vast range of processes at different...
