When we look at the standing of a forged knife today compared to the standing it held in the past, we see that a forged knife stands high. The Maker Manifesto, written by Mark Hatch, describes making as a part of human nature by saying “Making is fundamental to what it means to be human”. Making, being part of what it means to be human, gives each person a connection to one another. Empathy is the ability to understand and share someone’s feelings. The process on making a forged knife is a very…

The objective of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. Esterification is carried out by utilizing organic chemistry techniques, such as heating under reflux, extraction, and simple distillation. The acid and alcohol would be combined and heated under reflux; which heats/speeds up the reaction without having the reactants/products evaporate or explode. During reflux, the heating and condensing of the vapor prevents any loss…

Gold has been mined for centuries, dating back to the times of Ancient Egypt. Back then, the mined gold because it was beautiful and also imperishable. They’d make jewelry, cups, and decorate tombs with it. The way people mined it in ancient times was by using a process called “sluicing”. They would make wood troughs with riffles set in the bottom to create a zone to allow gold to drop through. The box is then placed in a stream to channel water flow. Today, the method of sluicing is still…

Hypothesis: we believe that High Frequency has more energy than low frequency. Explanation: For this hypothesis, we found that our calculations were wrong and we tested this by using the electromagnetic spectrum: radio wave, microwave, radiation, infrared, visible light, ultraviolet, X-rays and gamma rays. We went outside and made a simulation by walking and each group was one of the spectrums and we looked at how many more laps one group did than the other and we found that radio waves have…

In 1990,the Hubble Telescope,named in honor of astronomer Edwin Hubble,was launched into orbit around Earth. The telescope was packed with instruments that would give astronomers clear views of the universe in visible,infrared and ultraviolet light. Since the Hubble’s launch in 1990,it has provided a dazzling array images that have awed and inspired the public.More than 45 terabytes have been collected. The 45 and more terabytes that have been collected,provides lights into the…

Trees naturally sequester atmospheric carbon dioxide through photosynthesis and thus decrease global warming and its repercussions. Carbon dioxide is an essential component of the Calvin Cycle for the production of glucose, which is the primary energy source for plants as well as many herbivorous and carnivorous consumers. With the rapid increase in atmospheric carbon dioxide levels from anthropogenic activity since the Industrial Revolution, scientist suspect that carbon dioxide fertilization…

is also “designed for short-range, low-power unlicensed communications” found on mobile phones, notebooks, and handheld computers (Miller and Bisdikan, 19). However, IrDA utilize infrared information transmission and requires line-of-sight information paths while Bluetooth can connect to devices between obstacles. Infrared has a shorter electromagnetic wave length than radio waves and are stopped by a solid medium. Hence, Bluetooth’s radio wave connectivity is a better choice to incorporate into…

Is there any chance global warming, dramatic effects are changing the earth’s atmosphere slowly or rapidly? The industrial revolution begun in the mid- 17th century, it was a transition from agriculture era to manufacturing production era. This was the time where technology was improving and aspect of our daily life was changing. The first powered gasoline car (Benz Patent-Motorwagen) was made in 1807 and made by Karl Benz. Gasoline is made from fossil fuels, which is released into the…

Earth is a planet that has relatively stable temperatures. This is possible because of Earth’s atmosphere as it consists of a thin layer of gases that forms a “cloak” around the planet. There are 97 percent of climate scientists that agrees that people on Earth has changed its atmosphere in a considerable way over the past two centuries. The results of this is due to the greenhouse effect that causes global warming (Lallanila, 2015b). But what is the greenhouse effect? What is the greenhouse…

uniform. Something that might be expected if the universe expanded from a very small region (Lewis). The CMBR is the most accurate and precisely measured black body spectrum in nature, the CMBR was measured by the Far-Infrared Absolute Spectrophotometer. The results from the Far-Infrared Absolute Spectrophotometer showed that the CMBR is isotropic to roughly one part in 100,000 (Coffey). WMAP, The Wilkinson Microwave Anisotropy Probe, measures properties of the CMBR and in doing this reveals…
