106 04/26/2017 Debate of view points Russell: Henry Norris Russell was born in October 25, 1877 and died February 18, 1957. He dedicated Sixty years at Princeton University, as a student and professor. Russell, like many in this time, believed that stars were composed of the same identical elements that are present on Earth. The shared belief of physicists at the time was, “what we know here, must be true out there.” This changed in the 19th century when the use of spectrography arose.…

The purpose of the lab was to fully understand the Herztsprung-Russel diagram. We use this diagram to categorize stars with their stellar properties. By examining a star’s temperature, relative size, and luminosity for instance, you can plot them on an HR diagram. During the lab we did four different activities to understand the lab. The first was to look at a group of squares with different sizes, letters, color, and numbers. We categorized them based on color and then in order from smallest…

Russell Humphreys, an expert in YEC. One of these phenomena includes the spiral shape of the known galaxies. Humphreys suggests that the spiral shape of the galaxies are indicative of the age of the universe because the speed of the rotation of the stars in a galaxy is so high that if the universe was billions of years old then the galaxies wouldn’t maintain that shape (Humphreys, 2005). Another…

A star is known as “a fixed luminous point in the night sky that is a large, remote incandescent body like the sun” (Oxford Dictionary). The life cycle of a star is a very complex and magnificent process. Every star starts out as a nebula and have their own physical features. They all evolve and turn into something beautiful. Every star's physical features vary. Their diameters can range from 450 times smaller to 1,000 times larger than the sun. Temperatures expand from 3,000 degrees Celsius to…

in a perfect spot around its star. Nasa says that future missions will study whether which planets are life friendly and which are not. 24 out of 1800 planets sit in what is called the habitable zone, which means it is not too hot and it's not too cold, planets like these are also called Goldilocks planets Also, 24 out of 1800 planets are as close to earth sizewise…

Heraclides Ponticus and Aristarchus of Samos: “We know that the Earth is (or is not) at rest because...” The two philosophers Heraclides Ponticus and Aristarchus of Samos lived back to back as Ponticus lived from 390 BC – 310 BC and Samos lived 310 BC – 230 BC. Samos was a radical believer in the heliocentric theory of the universe, while Ponticus believed in the geocentric model; however, he believed that the Earth rotated on its axis, but it is at rest otherwise. Should these men have ever…

Stars are an appealing component of our universe. Because of our scientific advances, we know more about stars than ever before. They are born, they live, and then they die. How does this process work, though? The answer lies within thermodynamics. Thermodynamics has helped us understand how stars transfer energy and heat. Thermodynamics is a subject of physics that is concerned with heat and temperature. It is used to describe bodies of matter and their internal energy. Thermodynamics helps us…

Noah Yeasted A black hole is a large amount of matter in a small space. Black holes are one of the things that can be left over after a larger star dies. The other thing a larger star can become after it dies is a neutron star. A white dwarf is created after a smaller star dies. The only way for a star to become a black hole is if the star was 10-15 times more massive than the sun. The diameter of a black hole is approximately the diameter of New York City. A black hole’s gravitational pull is…

When a star is born it can take one of two paths. It can either take the path of a high mass star or the path of a low mass star. A high mass star will be between 10-50 solar mass and a low mass star will be between .8-10 solar masses. One solar mass is equal to M⊙ = (1.989±0.004) x 1030 kg, which is A LOT. Either path it takes, the one of a high mass or low mass star it will live about 90% of it’s lifetime in its main sequence. Once achieving nuclear fusion the star slowly contracts over…

Francois Arago’s “Report to the Chamber of Deputies” is a report presented about a proposed bill, granting M. Daguerre and to the son of M. Niepce life pension granting them a national reward due to their invention, which could not be protected by ordinary patent laws. He discusses the invention by the two men: the Daguerreotype. It is a machine that reproduces images received in the camera obscura onto copper plates. He noted that Daguerre should be well credited for the effort, time and money…
