Challenges & Impact Discontinuation of diesel In Europe, it is common to own a diesel vehicle as almost half of the total car sold in Europe were diesel vehicles. This is because the customers thinks that fuel efficiency is the biggest factor to consider when driving and the fact that the price of diesel is lower than petrol(Schipper, Marie-Lilliu et al. 2002). The corollary of better fuel efficiency is higher nitrogen oxide emissions. The fact that the popularity of diesel vehicles were…

Iridium-192 is a radioactive isotope that’s used daily in a series of world changing ways. It’s a synthetically produced metal, made as a by-product of nickel and copper, and the Iridium-containing ores are found in the U.S.A, Alaska, South Africa and Australia. Used both in the medical and industrial world, this radioisotope is underappreciated for its benefits to society. Though there are some risks, the reward undeniably outweighs them. Iridium-192 has a half-life of approximately 73 days,…

Acoustics is the branch of physics concerned with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules…

Castle Bravo over 90 million metric tons of coral reef and sea floor were ejected. A large amount of it was pulled up into the mushroom cloud becoming radioactive and creating fallout. Small amounts of radioactive dust or particles are harmless but many billions of these particles can cause radiation sickness and even death. As the mushroom cloud gets higher the winds get stronger and carry the fallout away from the blast site like radioactive seeds. This materials can be pulled up into the…

elements, such as O2. Thus, Avogadro’s hypothesis was completed neglected from the society until Josef Loschmidt emerged to the world of chemistry. In 1865, Josef Loschmidt, an Australian chemist and physicist, first estimated the actual number of particles in a given amount of a substance. He used kinetic molecular theory- Theory that can be used to explain Avogadro’s hypothesis. This quantity is known as the Loschmidt constant, which is 2.68767773 X 1025 m-3. The number was only twice…

Isaac Newton it is composed of “unimaginable small and swift” particles and because of this characteristic it was able to move over space in the speed of light (98). James Clerk Maxwel made that second affirmation cited in the last sentence, and he concluded that it behaves like a electromagnetic wave (98). This shows that light is composed by slight particles. Until now, the scientists were reluctant to say if light moves like a particle or like a wave. In the article “ What Is Light?” written…

"virtual particles," which are constantly popping into and out of existence. They do so in matter-antimatter pairs, which one of the particles has positive energy and the other has negative energy. Ordinarily, these pairs immediately destroy each other, but if the event of the particles switching between existence and non-existence occurred at the boundary of a black hole's event horizon, one particle could, theoretically, get eaten while the other went into space. If the negative-energy…

oscillate, and if it does so in a certain way, it appears as an electron, but if does in other ways, it can be seen as another subatomic particle (Güijosa). Essentially, everything is made of strings that vibrate in a way that give them distinct properties ("String Theory”). Similarly to an instrument such as a piano, different frequencies produce different particles, and this comparison brings forth unification (Greene 2005). This concept is reinforced by physicists’ recent detection of…
