Louis Arthur Ducos de Hauron was a French photographer born on December 8‚ 1837 in Langon‚ France. Not only was he a well-known photographer‚ but he was also a successful physicist and inventor as well. His invention of the trichrome process of color photography in 1869 has been one of the key developments in photography in the 19th century. His development of color photography is easily one of the most significant achievements in photography‚ and his basic concepts and techniques have been improved

I chose the Jacob’s Ladder as my Science Demo Project because I wanted to learn how the electrical current travels from the transformer and up the wires connected to the electrical source. The group currently consists of myself only. I chose to work alone because I did not want to worry about depending on others to complete the work‚ and I also wouldn’t have the trouble of lazy people just not even trying to complete it. Another reason why I chose to work alone on this project is so I wouldn’t have

DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing

Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper

with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the choice was mine‚ I would place them into violet light‚ because

I love seeing children have "light bulb" moments. It’s moments like those that let you know you have chosen the correct profession. I also chose teaching as my profession because when I was in elementary school I did not have good teachers to look up at. I struggled a lot in elementary school and my teachers just saw me as the problem child they did not have time to help. They made me feel horrible because I didn’t know the answer to a question they asked‚ or I needed help with something they thought

They each serve their purpose in the very diverse market of consumers. “Pushing promotions” are more useful at the start of a
