Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area. In this case, sodium alginate (SA) was used to be mixed with hydroxyapatite (HA) by using precipitation method to increase the mechanical and physical properties. The mixing of hydroxyapatite/sodium alginate effectively increases the densification and hardness…

Have you ever seen someone dive off the diving board? Do you enjoy swimming? Well now I’m going to give you a little more information on swimming and what the physics of it is. You will see swimming in a whole different way. Gravity is always affecting you while swimming. Even you don’t think it is. Force of attraction by which terrestrial bodies fall toward the center of the earth. Newton’s first law of motion has a part to do with swimming. An object in motion stays in motion until another…

Abstract: This paper is a report on the development of algebra throughout time. It’s slow, but nevertheless, unyielding progression brings us to the algebra we know today. However, it was not always based on the abstract, rather, it was born out of necessity. The need to calculate unknown quantities gave rise to algebraic methods and techniques practiced and taught even today. And, even though nowadays, algebra is a rather abstract mathematics, this was not always the case. It was through…

Before I went to watch glassblowing, I thought that it was just a hobby and it would be almost impossible to make a living off of it. Upon arrival to the Museum of Glass in Tacoma, I realized that this art form has artists that are both doing this for a living and doing this for a hobby. Glassblowing is an art that everyone should know about but many people have never actually witnessed it. I had the honor of observing and interviewing Lino Tagliapietra, who is considered by most to be the…

Hellenic refers to the people who lived in classical Greece before Alexander the Great 's death. Hellenic Greeks were isolated and their civilization was termed classic because it was not heavily influenced by outside forces. Hellenistic refers to Greeks and others who lived during the period after Alexander 's conquests. They differ from Hellenic in territory, culture, and political systems. After the collapse of Mycenae around 1100 B.C. and Dorian invasions, the Greek Dark Ages ensued and the…

the Egyptian Moscow papyrus (1820 B.C) with calculations of volume and area, a key concept of Calculus, inscribed within the tablet. There exists a plethora more of other early traces of Calculus, such as Exodus’ concepts of limits (408 B.C.) and Archimedes 's integral calculus (287 B.C.). The reasoning behind the math of these mathematicians is something could not be argued upon at the time, thus their concepts of math came to be known as justifiable truths. It has been centuries since the idea…

This paper will look at the series that converge to pi, and which ones slowly converge to pi and the ones that converge to pi fast. And after looking at these different calculations of pi, I will attempt to find a series that converges to pi even faster. What lead me to do this topic was my passion for math, and curiosity of learning about series and limits to infinity. Pi is something that everybody knows as 3.14, but they have no idea how it came to be approximated as 3.14. It is a complex…

While watching a movie maybe like Disney or Pixar have ever noticed little cameos of pervious characters in new movies. Some appearances might be a mere nod to another story just for the sake of a reference. While others seem to confirm the existence of a timeline shared by several movies. There are various theories about how Disney movies are connected. But there is a network of connections between Frozen, Tangled, Beauty and the Beast, Tarzan, and The Little Mermaid. So how are the movies…

Assess the Legacy of Alexander the Great Alexander the Great’s legacy was the spreading of Greek (Hellenistic) culture across a large part of the Middle East and Asia, and significantly increasing the relationship between the East and West, which led to improved trade and the sharing of ideas. During his 13 years of empire expansion, Alexander the Great transformed the world. He had numerous military successes, almost conquering the entire known world at the time, and he is considered one of the…

During the first two centuries of the Roman Empire the number of slaves increased dramatically. These slaves were mainly war captives, kidnapped and sold in Rome’s large slave trade. Slaves had no rights and the immoral Romans looked at slavery as part of everyday life. During the early Roman republic, debtors would be forced to work for landowners in order to work off their debt. When this practice was outlawed, slave labor was needed. Slavery was thus of immense economic importance. Slaves…
