Quantum gravity

Evie McCormack Mr. Acland B Block Physics Lab: Speed of Sound Essential Question Asked: How does the speed of sound differ between metals and gases? Background Information: The speed of sound is gauged by distance over time (distance/time). Certain aspects that can change or affect the speed of sound would include the density of the item through which the sound is traveling. Continuing on with that concept, when sound is…

the gravity ,it already existed but no body tried exploring it or even naming it . once when Newton was sitting below an apple tree .An apple fell on his head and he started imagining what made the apple to fall down. He went to more deep thinking and discovered that there is a force pulling every object on earth attracting the object to earth. He then actively experimented and tried to find out the speed of the force attracting us pulling to the surface of the earth. And he named it gravity…

The beam of electrons must hit the screen in one specific spot, as if you were throwing baseballs through a hole against a wall. (Hence quantum physics challenged our classical thinking about objects and was deemed controversial in its early years.) In fact, when a slit is closed, the interference pattern disappears — the photons or electrons form a single band that spreads out from the brightest…

For devices on Nano scale classical physics usually cannot explain transmission of electron through the insulating barrier with higher potential energy than kinetic energy of the tunnelling electrons and in this case the Heisenberg’s uncertainty principle takes place. Barrier penetration can be explained from Heisenberg’s uncertainty principle: If we were to say a particle cannot enter a barrier, we would actually say this particle is not there, i.e. its position uncertainty is Δx = 0 in the…

Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…

WERNHER VON BRAUN Wernher Magnus Maximilian Freiherr von Braun, the father of modern rocketry and one of the most important outer space engineers of the 20th century, was born on 23th of March 1912 in Wirsitz (Wyrzysk)(today in Poland). He was a child of a wealthy family from Germany. With their second son, Wernher, Magnus von Braun and Emmy von Quistorp moved to Berlin in 1915. In those years, Wernher von Braun became interested in music and astronomy. And his passion, astronomy, went on for…

I argue that many different branches of science are reducible to one fundamental one- physics. In this essay, I will use Pasteur’s work to demonstrate that biology and chemistry are reducible to physics - the study of interactions between matter and energy. By reducible, I mean that these sciences (and other hard sciences) can be simplified to the point where they deal with the same fundamental matters as physics. During the 1700s, chemists engaged in a long-standing debate over what caused…

Atoms are the most basic building blocks, everything around us are made out of atoms. Atoms are so small that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they…

Albert Vinicio Báez (/ˈbaɪ.ɛz/; November 15, 1912 – March 20, 2007) was a prominent Mexican-American physicist, and the father of singers Joan Baez and Mimi Fariña. He was born in Puebla, Mexico, and his family moved to the United States when he was two years old because his father was a Methodist minister. Baez grew up in Brooklyn and considered becoming a minister before turning to mathematics and physics. He made important contributions to the early development of X-ray microscopes and later…

The mathematician that i pick was Albert Einstein March 14, 1879- April 18, 1955 . He was a very smart and intelligent man who had many great ideas that has had an impact on the world today. The reason i picked him is because although he had a slight disability, he was still very successful in life and was one of the most known people from the past. Not only was he wise in math, but he was also very wise in mathematics. Albert Einstein had a very different but unique personality and way of doing…
