Photovoltaic cells vs. Reflectors:
-Photovoltaic cells: materials that when you shine energy when sun shines on material it produces electric energy small scale
-Reflectors: reflects the sun's light they track the sunlight, on big scale, use the heat energy from the sun to melt salts, and to boil water.
Coal Tar
- produced to coat the bottom of ships to preserve it, they didn't have any use for it anymore so they used it for town gas, gas lamps.
-Perkin tried to use it to make quinine for malaria, but made artificial dye. (mauve)
Naphtha, town gas:
- came from coal tar. 1819 a man who owned a clothes dying business was looked for naphtha which was found in coal tar, wanted to use it as cleaner for his dyeing machines, since it was being thrown away he was hoping to get it for cheap
he accidentally found out that the naphtha could dissolve rubber, this discovery made rubber useable in the clothing industry

Fuel Cells, Hybrid, Electric Automobiles
- Fuel cells: technology of burning hydrogen as fuel without burning it but by allowing hydrogen and oxygen to react without the fire and without wasting the energy, that is how electricity is created
-Hybrid: part fossil fuel part electric, burns gas to generate electricity, runs on electric motor, it can convert back and
-Electric cars: battery in environmental problem, if the electricity comes from fossil fuel then it is still harmful, but good for urban areas, limited range,
Plastics and Polymers
-Polymers: sport equipment largely made of different synthetic material (polymers)

-Invents ice machine-Air Conditioning
Carl Von Linde
-discovered refrigeration cycle
-1st to extract oxygen from air, and gas liquefaction
-Figured out how to cool beer through use of ammonia gases as opposed to air, because in Germany beer had to be made in cold season, inhibited making of beer in summer
-Von Linde: could only brew beer in non-summer months, because they used brewing technique that used cold air, used ammonia has highest temperature, liquefied the ammonia,
modern refrigeration uses
-make beer cold Von Linde used ammonia refrigerators
-used ammonia instead of gorrie's compressed air

Nicholas Appert
-Sterilized food in champagne bottles. French.
-stumbled on pasteurization, to preserve food in champagne bottles, worked great for a while, later used tin cans instead of champagne bottles.
-later canned larger amounts, and they weren't heat treating long enough, some spoiled
Pasteurization discovered by Appert(wasn't it Louis Pasteur)
James Dewar

Henry VIII
Wanted to divorce Catholic Church wouldn't let him, so he made a new church protestant church. Confiscated all church land because it was very wealth, he wanted to sell them but buyers wanted to survey them which initiated a frenzy, so they needed to map to see between distant points with cloudy light, which brought about the lime light by Drummond which needed a lot of energy, then was used in theaters

E=mc2 and Nuclear energy:
-e=mc2 is how nuclear energy is created
AC vs. DC Current
Tesla= AC he won, Edison= DC
Electromagnetic spectrum- Visible light vs other wavelengths:
- Longer wavelength lower energy, higher energy shorter wavelengths
Greenhouse Effect
-The process by which solar energy is re-radiated by the earth is captured by atmospheric gases
-the earth was trapping energy from the sun
-most important is CO2 because it's the only one we have control over, and it's the most abundant
Climate Change
- Due to carbon dioxide from the combustion of fossil fuels
Thermoplastics vs. Thermosets
- Thermosets= mixed together they react and harden, 1 chance to make them work like glue
- thermoplastics= melted and molded like plastic kitchen stuff, made from a melt
Fossil Fuels
-Fuel: substance that burns readily to release a significant amount of energy
-Fossil Fuel: Coal, petroleum, and natural gas

-Newton discovered gravity, but did not understand how it worked, how everything is affected by it and how it works
- Einstein explained what causes gravity
Higg's Boson Particle:
-all of space contains these Higgs particles, no way of testing back then.
Now they see if they slam particles together they would be able to knock some of the Higgs particles out.
Creates conditions similar to the beginning of the universe.
Internal combustion vs. Fuel cells vs. Electric vehicles:
- Fuel cells generates energy without too much heat 60-70& more efficient, you need water to transmit the electrons
-Internal combustion normal car, burn fuel lose energy lost in heat
Advantages/disadvantages of different Energy Alternatives- Wind, Solar, Fuel Cells, etc.:
Solar: design factors, thermal transfer, produce Electricity. Wind/Water: mechanical energy converted to electricity; disadvantage: not reliable. Fuel Cells: Water only exhaust, hydrogen produced by renewable sources, efficient than internal combustion engines; disadvantages: expensive, distribution system, produced from other sources of energy, fuel cells require catalysts made of rare materials.
Electricity wars, i.e.,:
AC vs DC:
Edison and the beginning of modern Science:
AC vs DC : direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.Direct current is a bit easier to understand than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current.
Edison and the beginning of modern Science: Although Edison (1847-1931) is best known as the inventor of the incandescent light bulb, the phonograph, and the motion picture, these innovations are a fraction of Edison's legacy. More than 85 years after his death, his accomplishments in the field of industrial research and development still resonate with scientists and engineers.
Edison First Industrial Research Laboratory:
Edison created the first industrial research laboratory in Menlo Park, New Jersey, in 1876, he was seeking to extend, not replace, this shop tradition.While Edison was working on perfecting the telephone, he started experimenting with the idea of being able to record the sound of the human voice.Edison's first major inventions at Menlo Park was the phonograph which was a basic machine that allowed a person to speak into a diaphragm that was attached to a pin that made indentations on a paper wrapped around wood.
