will actually be possible, but it certainly does seem worthy of trying out. The speed-of-light transfer of the encoded information from one photon to another demonstrates the possibility of secure communication between a network of remotely located quantum computers in the future.[3] This could lead to more secure networks on the governmental level (if used properly) and maybe it could be open for the public to use in the more distant
“Can there really be a unified theory of everything?”, Stephen Hawking’s concern seems to be the most challenging question for scientists for years. The beauty of science underlies in its uncertainty - because we do not know anything for sure, we do more research to form a complete understanding of the universe we live in. The more we understand, the less we know. Science seeks to explain our physical and natural world through experimental and mathematical reasonings. That is the reason why science
Born: APRIL 15, 1707 Parents: Paulus Euler and Margaretha Brucker EARLY LIFE Father came from modest folk, mostly artisians, while mother’s ancestors include a number of well known scholars. Leonhard received his first lessons in mathematics at home from his father. Around the age of eight he was sent to the Latin school in Basel and given a place to stay at his maternal grandmother’s house. To compensate for the poor quality then prevailing at the school, his father hired a private tutor for his
The first accurate recording using an electrocardiogram (ECG) occurred in 1895. Willem Einthoven was the first person to create an ECG that accurately depicted the recording of the heart’s electrical currents (Jenkins, 2011). Einthoven “was awarded the Nobel prize in Physiology or Medicine”(Nobelprize, 2014, p. 1) in 1924 for the discovery of the electrocardiogram (Nobelprize 2014). Not only did he configure the machine but he also created the deflections. They are the labels of the points on the
1. Why does the final electron energy not depend on the focusing cylinder voltage? - The final electron energy does not depend on the focusing cylinder voltage because it applies a force that is parallel to the magnetic field rather than perpendicular to it. 2. Do you think the electrons are emitted from the cathode with zero velocity, one velocity, or a range of velocities? Hint: The electrons inside the metal that are able to escape are a bit like a gas of molecules at finite temperature. - I
Let’s look at one other wave property of light. Light travels in transverse waves and this property is demonstrated by a phenomenon called polarization. Polarization means that the waves of light are restricted in their direction of vibration. Think of a horizontal string that you shake from one end. If you shake the string up and down, you will get up and down, or vertical, waves. If you shake the string back and forth, you will get horizontal waves. In this way, the string is said to be polarized
Albert Einstein Have you ever heard the bowling ball and trampoline analogy, if you roll a bowling ball onto a trampoline it will roll into the middle. Then if you were to roll some billiard balls behind it they would curve in towards the bowling ball. Albert Einstein is important because of all the changes he has made to the world of science and the military, with the Theory of Relativity, the E=Mc2, and the atomic bomb. In 1915 Einstein had first proposed the Theory of Relativity, in 1905 is when

His work led to important advances such as the control of atomic energy, space exploration, and applications of light. As a young boy born to Jewish parents in Germany, his teachers initially called him slow and lazy. However, by the time he left school at the age of 15, one teacher remarked there was nothing left to teach him. Einstein studied at the Institute of Technology in Zurich and received his doctorate in 1905 at the age of 26. That same year, he published five groundbreaking scientific
Bromine is one of the lesser known elements on the periodic table and is often underappreciated for what it does and has done for us. Starting from the scientific discoveries to the economical benefits, it’s help in improving the world is undeniable. The element was added to the periodic table in 1826 after being discovered by Antoine-Jérôme Balard in Montpellier, France. However, he was not the first to discover it. Carl Löwig from Heidelberg, Germany, discovered it a year earlier. When Löwig
