Albert Einstein, considered one of the sharpest minds in history, died unfulfilled. All of his life since he was a kid, he had been in awe from the natural phenomena of the world. Taken over by passion, Einstein put his whole focus on science. Even as a brilliant child, teachers thought he would never amount to anything, because of his lack of interest in anything other than sciences and math. Einstein and I share the same hyperfocus towards our passions that blindly leads us away from other…

In the early part of the 19th century the scientific community was in the midst of a debate regarding the nature of light, specifically whether it was a particle or a wave. Isaac Newton argued that light behaved like a particle whilst a man by the name of Christian Huygens argued that light was in fact a wave. Unfortunately, as Newton was the president of the Royal Society at the time and many other scientists would simply take what he said to be the truth, this meant that few scientists of the…

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.…

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]…

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…

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…

“Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter… I have chosen the word “atom” to signify these ultimate particles.” – John Dalton. John Dalton is a British chemist who was born in September 6, 1766 in Eaglesfield, England and died on July 26, 1844 in Manchester, England. At the age of 12, he started teaching at a Quaker school in Cumberland. Dalton worked as a farmhand…

Physics: Analogy of Light and Sound Light and sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the…
