Popcorn Kernels Around The Magnetron

The basic argument is that if we measure velocities in some region, then there has to be enough mass there for gravity to stop all the objects from flying apart. When such velocity measurements are done on large scales, it turns out that the amount of inferred mass is much more than

The Special Theory of relativity is an acknowledged physical theory that revolutionized advancements in the relationship between space, and time. The theory is one of the most interesting discoveries that are still used today in science fiction movies such as Star Wars, and Star Trek through the use of black holes, and time travel due to it’s astonishing results, and it occurrence at speeds close to the speed light, which can be appealing to a wide range of audience. This was a harvest from six years of extremely handwork by Albert Einstein. Einstein used resources that were widely available to the public due to his economic constraints. It wasn’t until 1905, when Einstein finally had finished and published his discoveries, and gatherings

1. Identification: In the 17th century, various fields of science began to advance. Isaac Newton combined the ideas of earlier scientists, and developed the concept of gravity.

In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light.

Galileo’s idea of diluting gravity using inclined planes worked like this: the acceleration of a rolling cart on an inclined plane is small, therefore is easy to measure; when the angle of the incline gets bigger, the acceleration will get bigger; by measuring the dependence of the acceleration on

Trying to change scientific theories would not be easy nor would it a safe. “Deeply held convictions had so to be broken in order to arrive at the formation of Galileo and Newton’s ‘classical physics,’ and it was the apparent self-evidence of these convictions that posed a great obstacle to the foundation of modern science. Commonly held ideas were plain not only because they appealed strongly to common sense.” It was hard for the uneducated man to wrap his head around ideas and theories that didn’t have a clear solution or that could be explained with experience. There were a couple theories that were hard to disprove just because they made a lot of sense and seemed to be reasonably explained with empirical data and observations. A good example of this is the explanations used to explain why bodies fall to the ground, bodies fall because they have a heaviness about them and tend to fall towards their natural position at the center of the universe. That is why everything moves towards the Earth because the Earth is at the center of the universe. This theory motion is also intrinsic, which means that the heavier the object the faster it moves towards the center of the universe. Such theories were easy to explain and easy to visually see and experience in everyday life and seemed to be true. The theory of intrinsic motion can be explained simply by dropping a feather and a large stone simultaneously and it could be easily perceived that heavier object is indeed falling faster. We know that this is not true thanks to the conurbations made by Galileo to the scientific study of gravity that objects accelerate downward at the same rate regardless of mass. This discovery is easily demonstrated which is exactly what Galileo did when he dropped two balls of different mass and proved that they hit the ground at the same

“By 1687, he had theorized that gravity was a force that could hold objects, such as the moon, in orbit around the Earth, and he worked out equations to prove it” (Challenging Limits). He then calculated the laws of motion that held the planets in their orbits around the sun. Along with his research, he invented calculus, the method for working out the speed of an object at any given moment during its path. By the 20th century, scientist could demonstrate atoms and the tiny charged particles they contained called electrons. The electrons are virtually invisible, but Leeuwenhoek used them from an electron microscope that magnified ten million times. Allowing future scientist to develop the MRI scanner, a precise diagnostic tool used to learn about the work of the brain. In addition to the discovery of atoms and their electrons, a physicist by the name of Albert Einstein formulated the theorem E=mc2. Stating that energy resided in matter itself. With this, scientist learned that atoms are our greatest repository of energy. Scientist began to ask if they themselves, “if we could split atoms, could we release the new, limitless supply of energy” (Challenging Limits)? Soon, scientist did split atoms that released massive surges of energy, but also produced lethal radioactivity. This groundbreaking discovery provided a possible solution to what created the

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

Lab 3 further practices accurate weighing/measurement through the use of popcorn kernels, moles, and Avogadro’s number. In order to complete the lab, it is necessary to record the weight of the popcorn kernels before and after popping, then based upon the data collected, calculations are then performed following the creation of a graph with Excel. The results from the experiment displayed the different ways of performing calculations to find the different weights of kernels as well as the amount of water loss. Furthermore, this information gives the experimenter the ability to calculate the amounts of kernels within a 1 pound bag. Not only has this lab help to practice accurate measurement, but also illustrate the importance of Avogadro’s number

What marks the start of the idea of physics is the Battle of Hastings- the battle that initiated modern monarchy- and the comet that flew in the sky that day in 1066. Everyone was asking “What is it?” and “Where did it come from?” Then that very same comet crossed over London once again in 1682 and the questions came up, “Where do comets come from?” Well, Isaac Newton dared to unlock the secrets of that comet. He also invented a reflective telescope that he used to track the motion of the comet. Owing to the fact

Thanks to Isaac Newton it makes it a lot easier for astronomer scientist today. Without Isaac’s discovery scientist would be still trying to figure it out today, and that would make a lot harder for an astronomer to advance in space study. Since Isaac discovered gravity, over time scientist have excelled in astronomy. Isaac would have had to of been pretty smart to figure out this.

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere. This can be related to the gravity force lab because you can make the person with either magnet bigger or smaller. When you made both bigger they were harder to pull apart but when you make them both smaller they were easier to pull apart.

Have you ever heard the legend about Newton and how he discovered gravity? Legend has it young Newton was sitting under an apple tree and all of a sudden he gets hit on the head apple. This legend is supposedly the real reason how the laws of gravity were created but it’s not all true. The real story which was told by Isaac himself is, he was barely looking out the window when he happened to see the fruit drop. Even then, some Newton scholars think the story involving the apples was made up.

Not only that, but a lot of the science were correctly given correlating to Newton’s Laws and Einstein’s General Theory of Relativity. The The visualization of Gargantua revealed that black holes’ "accretion disks" of infalling material were twisted into intricate and unique shapes — a find that had quite an effect on Kip Thorne.

The popcorn kernel performs a maneuver causing it to jump and somersault which dismantles previous theories of a rocket effect. Combining the video with acoustic recordings, the researchers identified the popping sound does not come from the hull fracturing but from the release of water vapor. The immediate change in pressure makes hollows inside the popcorn to vibrate and produce sound.
