Quantum entanglement

What if I told you that a laser can reach the earth all the way from space? You’d think it’s pretty cool right? Well it just so happens to be completely true! Scientists have created lasers to communicate from basically anywhere, and I’m here to tell you how it works. A laser shoots out a diverging beam that goes through the transmitter lens that creates a “well focused beam”. The well focused beam then goes through the receiver lens into the receiver diode. This is called laser communication.…

The purpose for this experiment is to observe the emission of spectra from several atoms including hydrogen and helium. Measuring the wavelengths of these emitted spectra will allow us to calculate energies of emitted photons. It is important to note that we will be using the Bohr model of the atom to denote the orbit numbers from which electrons in the sample are relaxing from in hydrogen. This will be important for the conclusions that we will make based upon the calculations using the data…

Introduction: The ability of substances within a solution to absorb light is a wonderful phenomenon as it aids in processes such as determining the concentration of proteins. The way that a solution absorbs light is due to the photoelectric effect. The way the photoelectric effect works is that when light comes in contact with the sample, the photons of light will react with its electrons. As the light travels through the solution, "a photon of light may interact with an electron ... [where]…

The decades surrounding the quantum revolution in science have been chronicled countless times. Among the ranks of noted histories, Uncertainty by David Lindley brings a unique perspective of a classic tale. The turbulent period in science marked the evolution from absolute determinism to probabilistic interactions. After this era, entropy did not always increase, only sometimes. By following the introduction of Heisenberg’s famous uncertainty principle, Lindley represents the giants of physics…

Only about 25% of the country of Darwin is electrified. For those who are not on the electric grid, lighting is primarily done by kerosene lamps and homemade candles. Kerosene fuel can cost as much as 50 cents a night, a substantial amount of money considering most Haitians only make about 2 dollars a day. Besides cost, kerosene also has many negative health risks, specifically harmful fumes and the risk of broken glass and fire. Due to these factors, many Haitians do not have much if any…

explain the behaviour of matter on the atomic level with the laws of classical physics however they were not accurate nor successful. It was not until the period between 1900 and 1930 where a revolution occurred and a generalised formulation called quantum mechanic was developed. And since the understanding of the structure of the nucleus of the atoms led to the development of different technologies and applications. The way how our understanding has grown will be discussed in the follow report.…

Exploration: Research Question: How does the travel distance of light waves affect the distance between the constructive interference fringes in the Double Slit experiment? Personal Engagement/Topic: Light is seen everywhere, artificial and natural. It is so common, that no one really questions it. But what is light made of? Intuitively, I would answer that visible light is a particle. It makes sense, doesn’t it? The photon from the source shoots into the eye’s retina, and the eye’s rods and…

Albert Einstein created a whole new universe of curiosity and discovery through research, experiments, and countless years of dedication to science. Throughout the years of his life, he faced many trials and failures, but those helped him set the foundations for many inventions and findings in the science community. Albert Einstein was an amazing scientist with a curious childhood and an extraordinary adult life, filled with discoveries and findings that ended up impacting science in several…

We now use the method described in Section 2 to studythe effects of electron-phonon interaction on the electronic transport properties of (C60-1X1)2(X=N,B) molecule. We set tC-C=2.5 eV, αC-C=6.31 eV/Å, KC-C=49.7 eV/Å2 [35] tC-B=1.17 eV, αC-B=6.04 eV/Å, KC-B=51.1 eV/Å2,tC-N=1.05 eV, αC-N=6.13 eV/Å, and KC-N=49.6 eV/Å2 [36] and T=300 K in the calculations. The doped atoms are located at about the same distance from each lead and they are indicated with a different color from C atoms in each…

The Atomic Theory The atomic theory serves as the basic foundation for the study of matter; it is of major importance to the study of Chemistry. The atomic theory has an interesting and lengthy history that shall be discussed. Furthermore, it has been perfected and discussed by many chemists over a number of years; all of their brilliant minds put together into one. There have been drastic changes to the atomic structure in modern times, proving we still do not know everything. Technology…
