Chapter 6
How does John Cassidy illustrate the size of the sun and its distance from earth?
Football and pepper corn 25 m away
Chapter 6
What creates the huge pressure in a large star? and what is the effect?
Gravity; compression
The size of a star is the balance between which two forces?
Outward push a heat and inward push of gravity
Chapter 6
Where does the matter on planet earth come from?
Supernova, explosion of a very large star, creating all the elements we can find on earth, "star dust"
Chapter 6
What are asteroids and shooting stars?
Giant floating rocks in our planetary system; Shooting Stars are rocks that burn as they enter the atmosphere
Chapter 6
Why does life have to be close to a star?
Energy needed lo live
Chapter 6
How does Dawkins describe the leaf?
Leaf is a power generatorstation that provides food for animals
Chapter 6
What is coal?
Decayed plant matter that is compressed and stored over millions of years
Chapter 6
What happens in the cycle of life?
Energy that is ultimately created by the leaf is used by a series of animals thriving on each other
Chapter 7
Who discovered the spectrum of light?
Isaac Newton
Chapter 7
What does the color "white" mean?
Light with a mixture of all colors
Chapter 7
What was Newton's "experimentum Crucis"?
It was a beam of light, separated into individual colours by a prism, then re-united by a second prism and finally spread out again
Chapter 7
How does a rainbow work?
It's the effect of millions of water drops breaking sunlight into the spectral colours
What is light?
Visible electromagnetic radiation
Chapter 7
Which spectrum of light can humans see?
Between unltraviolet and infrared
Chapter 8
Why is the Big Bang theory accepted by most scientists?
Because predictions based on it turn out to be true in observations
Chapter 8
When did the BB happen?
13 - 14 billion years ago
Chapter 8
What is a galaxy?
It's a cluster of stars
Chapter 8
What is the parallax method of measuring distance?
Outstretched arm and each eye closed will provide a jump in the distance, this allows you to calvulate the distance of an object, helps to determine distance of close stars
Chapter 8
What is a spectroscope?
An instrument (prism) splitting light into various wave lengths
Chapter 8
How do we know which elements are present on distant stars?
The spectroscope reveals a barcode of light, telling us which elements are there emitting light of a particular bar code
Chapter 8
What is the Hubble shift?
It's a shift of the bar code towards the red
Chapter 8
What is the doppler effect?
Sound waves change according to how they move (deeper when moving away, higher when approaching)
Chapter 8
What kind of movements do all the galaxies in the universe display?
The galaxies are moving away from each other
Chapter 8
How do astronomers explain the age of the universe?
They can calculate the expansion rate and work backwards towards when it started
Chapter 9
How does Dawkins explain the sightings of aliens?
Sleep paralysis: People who suffer from it have hallucinations about aliens
Chapter 9
What is the "Goldilocks zone"?
A zone where a planet is close enough to the sun (energy sources) and water in liquid form available
Chapter 9
If there are living creatures on other planets, what do they look like?
Appearance depends on characteristcs of planets (amount of gravity etc.), organs of perception for higher life forms, seeing/sonar (or electromagnetic radiation at different spectrum); but all this is speculative, we don't know
Chapter 10
What happens to continents over time?
They move and reshape
Chapter 10
At what speed do continents move?
He compares it to the growth of a fingernail. It's little for humans, but important for geological time
Chapter 10
What is a plate tectonics?
It's the science of how continents move. There are seven plates that cause movement on the surface of the earth
Chapter 10
What is the modern theory of plate tectonics?
The earth core consists of hot, liquid lava in the form of "honey" on which the plates float
Chapter 10
What is seafloor spreading?
The movement of plates away from each other, submerged under the sea
Chapter 10
What drives the great plates of the earth in various directions?
the heat of the earth core melts lava and leads to movements in the earth crust
Chapter 10
What is subduction?
Two plates collide, one plate moves under the other and pushes the border of the other plate up
Chapter 10
What formed the Himalayan Mountains?
Subductions of indian against eurasian plate
Chapter 11
What is Murphy's Law?
Everything that can go wrong will go wrong
Chapter 11
Why do bad things happen?
Everything happens by chance or according to the laws of science. It's only the human perpective which makes some events "bad". But it's also an illusion as you remember bad events more strongly
Chapter 11
While rejecting Murphys Law, Dawkins believes that something like it's a work how?
There is natural selection, the struggle of survival, so we still have instinctive fears that animals are dangerous, they are trying to "get" us. The world is full of enemies to our survival
Chapter 11
How does Dawkins explain superstitious beliefs?
Superstitious are the result of these fears
