He talks about applying game theory to the "decision paralysis" people have surrounding the global warming debate, using a "decision grid." He explores misunderstandings most people have about the nature of science, and whether or not science can provide certainty about important questions facing society. He emphasizes as a starting point the acknowledgement, whether one is a skeptic of global warming or a "panicked activist," that one could be wrong about global warming. He argues that the evidence is not what is most important in the climate change debate, because each side has "evidence" to support its conclusions. He talks about "confirmation bias," and how it makes it difficult to find out the truth about global warming. He explains why it is less important to personally live "green," and why others kinds of social environmentalist activism is more important. He details why America's mobilization in World War II and also modern social networking on the internet are the only two things that give him hope regarding responsibly responding to climate change.It is also helpful in business decisions.

A woman affected with color blindness marries a unaffected person so what is the probability for being color blind. Mother-XBXb and father is Xby.

XB Xb XB XBXB XBXb y XBY Xby			Key: B-not affected by color blindness b-affected by color blindness.

()Decision Paralysis:

A condition of not being able to decide on a matter when there is no clear cut best option. It leads to an ever longer period of gather more information in the hope that more information will guide the decision maker to an option that is clearly better. Exactly the same as "Analysis Paralysis".

Horizon Illusions - Is Seeing Believing?

Horizon explores the strange and wonderful world of illusions - and reveals the tricks they play on our senses and why they fool us. But all this trickery has a serious purpose. It's helping scientists to create a new understanding of how our senses work - not as individual senses, but connected together.

Examples-

1.Spinning diamond

It can appear to spin in both directions because the sequence of 2-dimensional images on your eye is identical for a 3-D diamond spinning either to the left or to the right. When we look at the spinning diamond, our brain doesn't actually know which way it is spinning. And because both directions of motion are possible, it bounces between the two options depending on where in the diamond we are looking.

2.Brightness Illusion - colours out of place

If you put the mask on the picture you will see that they are in fact the same brightness.

This happens because our brain does not create its perceptions of brightness from only the intensity of a single surface or light in a scene, but according to the relationships between all the surfaces and lights in the scene. In other words the brain always uses context to figure out what's in front of it.

3.Impossible Slopes - depth perception
We see the balls appear to roll up the slopes of the model towards the middle.
This is because all the information in the image is consistent with the supporting legs of the model standing at right angles to the floor. Because of this, the brain interprets the middle leg as being the tallest leg in the model. Which means the ramps must actually slope upwards. As a result, the rolling balls appear to roll up - now down, which they really are.
Because the image hitting the retina is only 2 dimensional, in order to see the world in 3D, our brain must create its 3D perception based on its past experience of the most likely 3D configuration given the 2D image. Sometimes this means even perceiving a world that goes against the laws of physics.
When you change your perspective you see the slopes actually point downwards into the middle.

  

                   

 

Reflection  on language

I first of all think that it is very difficult to define the word language. I, personally, think that it is a form of communication using symbols and your vocal chords. I think that there is a difference between language and communication. As language is a form of communication. For example a monkey peeing on a tree to mark its territory is communication, however it is not using language as someone talking to someone on the phone would be communicating but also using language. When it comes to the problem ‘can you know something without language?’ I think that you can, because you have your eyes and you can recognize it. Also how are babies supposed to learn anything without language? Another thing I found interesting was the concept that your amount of language depends on where you are from and what your climate. For example in England it rains a lot so you have many words for rain, such as drizzle or spitting, or raining cats and dogs, however, in for example Egypt, there is probably only one word for rain. So in many ways language is a way of knowing for to know you have to communicate.

Language and Thought

1. Why is the ruthless totalitarian regime, described in Orwell’s novel, purging Oldspeak and imposing Newspeak?

-They are imposing Newspeak in order to eliminate words that are looked at as unnecessary or useless. They believe that there are extra words in Oldspeak that could be replaced by simply changing one word so that with these changes, could have the different meanings of words. For example, instead of “good” and “bad” it will just be “ungood.” By removing Oldspeak, many words will be removed as well, in order to establish a simpler and more direct use of language.

2.What assumptions are being made about the relationship between language and thought in passage?

-It refers to something such as not thinking, saying that the relationship will obtain such a trait, it is suggesting that by imposing Newspeak and eliminating many of the words that exist in Oldspeak, language will become so limited to certain words that there will not be options in way in which one can express themselves. In other words, people will have only one choice of expression because only one word will exist, due to all “unnecessary” ones being taken out. 

Real Life Situation Based On Religion And Castes

Identify a real life situation and choose a good knowledge question on it.

Religion and castes

.Religion is all over spread everywhere.There are diversities of culture which can be found all over the huge world. Tribal can be found in some parts of the world.They contain the same blood.Religions contain as their parts are called castes.

1.Knowledge Question: Religions have diversities then why is racialism,regionalism still there?

2.Knowledge Question: people say and believe that there's one almighty god then why does every caste believe different gods ?
