Sound - Edward R, Ben, Edward T

Hearing is the universal alerting sense in all vertebrates. Sound is so important because animals are able to hear events all around them, no matter where their attention is focused. Sound is also a vital transportation / communicaiton method used by humans / animals alike. Bats pick up ultrasound emmited by themselves to travel and hunt. Dolphins identify prey and objects by using ultrasound. Humans communicating by using sound which becomes the basis of all language.

Sound is a 360 sense. It has the most coverage out of all the senses eg. you may hear an explosion from a long distance away but you may not be able to see it, smell it, or taste it. It isn't primarily focused in one certain direction at one time. For example if a car was coming at you from behind and you were deaf you wouldn't know that it was there and you would be run over. But with sound you would hear it coming and dive out the way. Sound is also a vital part of music as it is very influential to the sub-conciousness of the human mind. If you only had 1 sense left, sound would probably be the most effective sense to live off of. eg. blind people can hear the world in strange ways.

FUN FACTS :D D: :D

- In Africa, a tribe of people call Maabans live in such quiet that they can hear a whisper from across a baseball field ‹ even when they are very old.
- Sound travels at the speed of 1130 feet per second, or 770 miles per hour.
- At 115 dB, a baby's cry is louder than a car horn.
- It does not matter if you like the sounds you are exposed to. An orchestra playing Mozart at 120 dB will damage your hearing as quickly as Metallica playing at 120 dB.
- The hearing of a dog is more sensitive than humans. Dogs can hear much higher frequencies, which is why they respond to "silent" dog whistles.

Ruby's knowledge claim

This is a knowledge claim about the creation of the world, according to the Chapter of genesis in the Christian Bible. God was the one who created the whole world, in six days, from the universe, then earth etc... There are six different areas to consider to examine whether this claim is a reliable one.

1)Logical consistency - Although this video is from a book written by men, i believe this story is still very reliable. According to the bible, God first created the heavens and earth, then the landscapes, then plantations, then animals and finally humans. I think this is a very logical sequence of how the world could have been created. If there were no plantations, animals won't be able to live. If there were no heavens and earth, landscapes cannot be created. Therefore the whole order of how the world was created is very logical in my opinion.

2)Observational reliability - Firstly, the video is an anime, therefore there is no reality observations availiable. However, by lookin at the world we are living in today, everything mentioned in the bible created by God is extistent today - trees, sea, animals, humans etc... We can at least confirm the story was not crazily made up, there're observational proofs in the world to support the claim.

3)Awareness of value, judgments and propaganda - This claim's value is based upon christianity, perhaps in some ways it is propaganda as it is one of the most fundamental basis of the christian belief. Since religious events has no definite proof, it can be argued that this claim is therefore a ofrm of propaganda.

4) Authority/ citation/ peer review - this claim is from a strong powerful authority - the christian bible which is the best selling book ever. The christian faith is also a long religion and affects many in the world. It would be wrong to say this claim is simply a story made up randomly.

5)Awareness of source, intention and audience - The intention of this claim is to make people believe in the omnipotent power of God, and the audience is for people who are non-believers or also believers of God.

6) Awareness of knowledge selection, priotization and editing - In this particular anime, the full details of the genesis story wasn't shown. The more interesting parts were selected and priotized to perhaps make the anime and story sound more interesting and attract the audience.

In conclusion, although there are certain areas where this claim may not be reliable; it is still important to note that this claim is from a very powerful authority and religion, and that the story is not random but is logical and makes sense.

Knowledge Claim Astrid + Edward R

Moon Landing: Fake or Fact?
Moon Landing.

We are claiming that the moon landing is a hoax. Bill Kaysing was a librarian/writer of technical publications and advanced research at Rocketdyne Systems from 1956 to 1963. He states that it was estimated in 1959 that there was a .0014 chance of landing man on the Moon and returning him safely to Earth. This took into account the effects of radiation, solar flares and micro meteorites. He could not believe in 1959 that man could go to the Moon.

Evidence states that an important factor to take into consideration is the great variations in temperature that the film would have had to endure whilst on the lunar surface. The temperature during the Apollo missions were recorded as being between -180F in the shade and +200F in full Sunshine. How could the film emulsion have withstood such temperature differences? The astronauts can be seen to move between the shadows of the rocks and then into full sunlight in some shots. Surely the film would have perished under such conditions? If the film used during the Apollo missions had such qualities as to withstand such differences in temperature, why are Kodak not publicly selling them in today's market?

There are other series of evidence expanded in the video's content.
