Asal Bahmani 12.20.16 Franey//Adams Chem P.6 Going back through history the experiments, discoveries, and works of past scientists such as Democritus, Dalton, Thomson, and Rutherford have afforded us the opportunity to draw from their ideas to formulate a modern view and accurate understanding of the atom. Thanks to the evolution of atomic models. In the beginning, Democritus viewed the atom as a tiny, solid, round sphere, that was unable to be cut. He created the first model of an atom, that…
“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…
The definition of honor is high respect or esteem, my definition of honor is a person that is highly respected for doing something to contribute to the community. Albert Einstein (March 14, 1879 to April 18, 1955) did many things during his lifetime he had many accomplishments and awards. Albert Einstein is highly respected by many people. Albert Einstein was physicist and mathematician who developed the theory of relativity. In 1921 Einstein won a Nobel Prize for physics and the photoelectric…
Keep batteries stored in LiPo-safe bags. How will you flow between the activities? Start with a whole group safety briefing and watch the Droneology videos all together on the projector. Break into teams to build, then come back together in P2 to talk through flight dynamics and essential terminology. Split to individual computers to take the Lesson 2 Quiz in C1. Come back together to watch the next batch of videos in C2 and end with a review of safety procedures in the DP. What does FPV stand…
Luis Miramontes was a famous Mexican chemist who invented birth control. He was born in March 16, 1925 at Tepic, Nayarit. His full name is Luis E. Miramontes Cardenas. At the National Autonomous University of Mexico, he received his first degree in chemical engineering. He was a researcher at the National Autonomous University of Mexico in the Institute of Chemistry. He also was the faculty of chemistry there. Not only that, but he was the director and professor at the Universidad…
Ernest Rutherford was born in rural Spring Grove, on the South Island of New Zealand on August 30, 1871. He was the fourth of 12 children, and the second son. His father, James, had little education and struggled to support the large family on a flax-miller’s income. Ernest’s mother, Martha, worked as a schoolteacher. She believed that knowledge was power, and placed a strong emphasis on her children’s education. At age of ten at Foxhill School Ernest Rutherford received his first science book.…
Natural selection is a concept that has long since interested me, I consider it to mean “survival of the fittest”. Thus, looking upon this title, I deduced that the metaphor, which is used for comparison, implies the following principles of natural selection apply to knowledge development: there is variation in knowledge, the ‘fittest’ knowledge is most suitably adapted to the environment, and superseded knowledge is not fit to survive. Questions and doubts thereby arise: What is meant by the…
rnest Rutherford was born on August 30, 1871, in Spring Grove, on the South Island of New Zealand. Rutherford resided in a family of 12 children, whose mother was a teacher and strongly believed in a good education for her children. Without this education, Rutherford would not have affected the atomic structure as much as he did. Rutherford, specializing in Physics, in 1895 was the very first research student at University of Cambridge’s Cavendish Laboratory in London. While at the Cavendish Lab…
Conclusion Through burning varied solutions in a flame the information that is found becomes very useful. While burning any solution in a flame it produces a flame on the visible line spectrum. This flame color allows for a brief understanding of the energy the solutions possess. The least energy in the visible light spectrum is the color red and the most energy is violet. According to the data found in the experiment we come to the conclusion that the least energy is Lithium Nitrate due to…
“My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.” -Stephen Hawkings. This is exactly what Stephen Hawking is working to do by piecing together parts of the universe. Stephen Hawking was born on January 8, 1942, in Oxford, England. When Hawking was young, he showed a strong passion for science and the sky. When he was 21, he was diagnosed with amyotrophic lateral sclerosis, also known as ALS. ALS is a very progressive disease…
