Foundation series, and recent happenings

I recently read the Foundation series, ( by Issac Asimov ). It was a pretty good book , I did not like the swearing, but the story was interesting. It really is an amazing science fiction story, based in the future, when mankind grew to inhabit almost all of the galaxy's planets. The story is a astronomical-psychological science definition fiction , blending both categories of science. The plot is that a psychologist  ( Hari Seldon ) predicted that the Galactic Empire ( which had conquered most of the galaxy, and has a capital named Trantor ) would fall soon, and thirty thousand years of barbarism would follow before a second Galactic Empire would rise.  He then devised a plan that ,with the help of two foundations, the time would shorten to 1 thousand years only. The book goes on through many Seldon crisis , and where there was a crisis, Seldon  ( having predicted it ) would hologram himself to the leaders of the foundation and explain how to overcome it. But his predictions did not take in the fact of the Mule, who was a mutant,( and could control emotions ) and he conquered the First foundation. Later a second foundation-er made it so the Mule would die in a year or so, and so restored power to the first foundation. At the end of the book everyone tries to find the second foundation ( where there are people who can control minds ) but failed ( obviously ). 


We have many blackberries in our yard, and they are in season. Were are picking them and they are delicious. There are so many !

I am taking HIST 201 , So far in my history course we have covered the beginnings of Human kind to the Axial age ,and I am going to take my midterm soon. I have almost finished my art class ( ART45 ) and I have read a book that goes along with my history course. It is called : The Conquest of Gaul : Caesar .Which is written by Julius Caesar, and describes his campaigns in Gaul ( France ) and his final conquest of it. It is interesting and it is cool to listen to battle descriptions. Julius Caesar conquers some of Gaul, but then tribes revolt and then he conquers them again, By 51 BC however , all of Gaul is under the Roman yolk. The book also describes his crossing of the Rhine into Germany and his invasion of Britain. 

We have been going to the beach a lot recently, boogie boarding and surfing. Its really fun, you have to catch the wave right as it crashes for maximum effect.

Chapter 4

This Chapter is about energy. Energy makes matter change and move around. Matter is the stuff in the world, anything that takes up space. Electricity, Light , motion and heat are all forms of Energy. Energy changes form a lot.

 Benjamin Thompson was a scientist and count. He was born in Massachusetts in 1753. He invented many things including efficient fire places. He did an experiment that proved friction could turn into heat energy.

The Laws of the Conservation of Energy state that energy can not be created or destroyed. The Atomic theory of matter says that atoms and molecules vibrate and move around. They move around more in gases and liquids then solids. Heat = the energy of motion. So when molecules move around fast it creates heat. Physical change is when things melt, evaporate,condense and freeze. It is when matter changes states, from solids( in solids the molecules vibrate but do not really move around) to liquid( in liquid the molecules move around more  ) to gas ( and in gas the molecules move around the most ).

In Physical changes the matter keeps the same atoms and molecules. In chemical change though the molecules change. The matter becomes something totally different. Fire is an example of chemical change. In fire the starting molecules ( Oxygen and wood  ), have more Chemical energy than the products ( carbon dioxide and water ) .So in order to stay true to the laws of conservation, another product is heat and light energy ( fire ).Chemical change does not create energy, it conserves it.

 1 water molecule is not wetter then one rock molecule, because you need many molecules together in a system to feel wetness. We are systems of molecules that experience other systems of molecules.

Chapter 5
This chapter is about  Forces. When Matter changes its energy then a force is being acted on it.

 Galileo measured gravity ( the force that attracts things. When a apple falls to earth, gravity is acting , attracting the apple to the earth and the earth to the apple. Since the earth is way bigger than the apple you cant really see the earth being moved towards the apple because it is so small a force. )

 Issac newton discovered gravity, he also invented Calculus, so he could measure the strength of gravity exactly. Newton made the Newton's laws of Gravitation Attraction and Newton's laws of motion. They say that the farther apart the objects are and smaller the mass ( mass is how much matter there is in something ) of the objects - the weaker the force of gravity. But the closer together the objects are and the more Mass that have -the stronger the force of Gravity. Gravity applies everywhere in the universe. It is the force that makes the moon orbit the earth and the earth orbit the sun.


There is a/are force/forces stronger than Gravity. The 2 separate forces are electricity ( electricity is the flow and charge of electrons . One form of electricity is static electricity. Static electricity is stronger than gravity. One way to show this is when you rub a balloon on fur and then pick up paper. Gravity is acting on the paper , but it can not keep it on the ground. Why this happened: When we rub the balloon on the fur it rubs of some electrons on the fur. The electrons come on the balloon and make it negatively charged. The paper is neutral ( has same number of protons as electrons ) so when we bring a negatively charged balloon by it the electrons near the surface move away from their alike counterparts. This makes the surface of the paper Positive. Since unlike attract the positively charged surface of the paper goes towards the negatively charged balloon.) and Magnetism ( Magnetism is a force field around a Magnet that attracts metal like Iron.  Magnets have a North and south pole. ). Together they are called Electromagnetism ( Electromagnetism ). Magnetism and electricity are closely related to each other and are parts of Electromagnetism.

Some of the book Science by John Farndon


Energy has many forms heat, electricity , light and others. Almost all of our Energy comes from the Sun. Some directly from solar Panels, but most indirectly from fossils fuels( coal, oil, petroleum and Gasoline. These are fossils and dead organisms compressed and under immense pressure by layers of soil and land , that turn them ,after many years , into Oil and other fossil fuels. These fossil fuels are considered nonrenewable, because It takes a very long time for them to form. They are bad for the environment not only because they are nonrenewable , but also because burning them releases air pollution  carbon monoxide and other compounds bad for the environment ). The dead organism got their energy either directly from the sun ( plants and photosynthesis ) or indirectly from  eating the plants or eating the animals that ate the plants. Energy efficiency is the measure of how much energy is wasted. Machines that waste very little have good energy efficiency. Energy is a form of mass; mass is a form of energy. Absolute zero is the coldest temperature of all. On the Kelvin scale it is 0 , while on the Fahrenheit scale it is -459.67 degrees. Theoretically it is when molecules cease to move, but this is around impossible it was almost reached in a Finnish Laboratory. Conduction is 1 of 3 ways heat moves. It is when heats spreads from hot places to cold places. The other 2 ways are convection ( when warm air or water rises ) and radiation. You can convert Fahrenheit to Celsius by subtracting 32, dividing by 9 ,multiplying by 5.Like this : 90 degrees Fahrenheit - 32 =  58 / 9 = 6.4•5 =  32. So 90 F = 32 C . Celsius is based on waters boiling and freezing points .  0 degrees Celsius is the freezing point of water , while 100 degrees Celsius is the boiling point of water. 


Summary of the book Milestones in Science
Light , colors and sound
 Light is a form of energy that is made up of waves and particles , called Photons. For creatures that see , light is very important. A long time ago people made artificial ( fake, man made ) light . Later scientists learned about rainbows, optical instruments , light , cameras and more. Sound is also important to us. 

Magnifying glass
The Romans observed that water filled glass balls magnify , zoom in on or make bigger ( in this case only visually ) objects. Around 1,000 years later ( about 1020 46 years before the Norman conquest of England ) an Arabian scholar, official and scientist ( Abu Ali al-Hasan Ibn al-Haithan. He was an official in Egypt. But he liked science more than his job as an official. He was the first person to make the Camera obscura and magnifying lenses he also wrote a book called Kitab-al-Manazir, which was about optics  ) looked at curved glass and found out they can be used as a magnifying lens or burning tool. He set up the base for further scientific research in optics. 

Camera obscura

A camera obscura is: when light enters through a small hole into a dark room and makes an upside down picture. Abu Ali al-Hasan Ibn al-Haithan made the first of these. Artists used these for drawing, but not until 1840 were they used for photography. 

Fast fact
The first eyeglasses were made of clear gemstones not glass ! The man who is credited as the European inventor of the eyeglasses is called Roger Bacon ( he was from England  ). He knew about Abu Ali al-Hasan Ibn al-Haithan's inventions though. Roger Bacon was an amazing man , he predicted airplanes and microscopes way before they were invented. 

Telescope
We don't exactly know invented this , but it might be Hans Lippershey ( supposedly Hans held many eyeglasses in front of each other , and on accident found " that they magnified things in the distance ". Hans was a great lens and eyeglasses maker that was born in Germany, and later moving to Holland became a citizen of Netherlands ) a Dutch-German man or Leonardo Da Vinci ( An amazing genius-polymath ( Polymath means : good at many things, and boy was Leonardo good at many things like: Painting, Science, Math, Writer , Musician and Inventor ) of the Renaissance. He is Famous for painting the Mona Lisa )an Italian ( He might have made a small,weak telescope way before Hans ). Either way in 1609 Galileo Galilei ( Galileo was a bit of a Polymath to : he was good at Math, Astronomy, Physics and Inventing. He discovered the Law of Falling bodies  ) built a newer better telescope and looked a space. He discovered that the moon had craters and ridges, and found moons orbiting Jupiter. In 1611 ,2 years after Galileo discoveries , Johannes Kepler ( he was an Austrian -German ) published a book that told you how to make a better telescope ( an Astronomical Telescope that turned everything upside down, but since planets were and are mostly close to a Sphere it did not matter )  and told you how a telescope works ( Telescopes capture and Magnify light with Lenses and mirrors. A Binocular is actually 2 Telescopes stuck together. Refractor Telescopes use lenses to gather and Magnify light, while Reflectors use Mirrors. The Aperture of a telescope is the diameter of the main lens ). 

Microscopes and Microscopy
There are many types of Microscopes, like Electron Microscopes and Light/ Optical Microscopes. The one were are going to write about here is the Light/Optical Microscope.  It uses Lenses ,like the telescope , to magnify very small things. It is not certain who invented it, maybe Zacharias Jansen , maybe Anton van Leeuwenhoek ( who were both Dutch ), Maybe Galileo but one thing is know for certain. After the years the Microscope was invented Ernst Abbe ( a German ) calculated the way to get the best picture, he improved the Microscope a lot.   

The Electromagnetic spectrum
This is the Spectrum of Radiation from Radio waves to Gamma rays. The wavelength is longer in Radio waves than in Gamma Rays. Visible light is all the light we can see and it only makes up a fraction of the spectrum, the colors of visible light ( from longest wavelength to shortest ) are : Red,Orange,Yellow,Green,Blue,Indigo and Violet. Infrared radiation is right below Red on the electromagnetic spectrum, it has a longer wavelength than red. Ultraviolet is right above violet on the electromagnetic spectrum, it has a shorter wavelength than violet. Beneath Infrared are Microwaves ( which heat up food in a Microwave oven ) , and below Microwaves are Radio waves ( radios use these waves ). Above Ultraviolet are X-rays, and above X-rays are Gamma rays. Issac Newton discovered visible white light was and is actually made out of visible colored light in 1672.

Diffraction and Refraction
Diffraction and Refraction are proprieties of light waves and other waves. Light usually travels in a straight line, but when something gets in its way ( like glass ) the light gets bent and this is called Refraction. Light changes speed in materials that have more density ( how tightly packed the molecules are ), this causes the bending. How much the light bends is called the angle of refraction." Diffraction is the bending and spreading of waves "

Earth and the atmosphere

Earth
Is the only know planet that has life. Why ? Here is your answer.
We are not to far away or to close to the sun ,making temperature
just right to live in. The atmosphere also helps . It traps the suns
 heat rays but deflects ray that could hurt us. The atmosphere is made
 up of gases that include oxygen and nitrogen . Many living things
need oxygen to survive including us :). There are 5 layers of the atmosphere
 (the higher you go the thinner the air gets)  they are :


The Exosphere_________________________________________
Is the highest and thinnest layer                                                                                                        

The Thermosphere   _____________________________________
Is the hottest layer. There is very thin air here to .

The Mesosphere ________________________________________
Here is where most meteors get dissolved. This is the coldest layer.

The Stratosphere________________________________________
The Ozone layer is here.

The Troposphere________________________________________
This is the lowest layer . This is also called the weather layer.
--/\______________/\____/\_______________|


Another thing that helps life on earth is the water. 71% of the earth is water. All living things need water to survive . Earth is the 5th largest planet in the Solar system making its gravitational pull not to strong or to weak. Earth also has a magnetic field because of the core. Scientist think that the magnetic field defends us from harmful rays.

Comets

Comets are made up of gas dust and ice .

They are in the Oort cloud and the Asteroid belt.

You rarely see a comet in your  life.

When a comet gets close to the sun the ice

start melting. Making a tail or coma around

the ball or nucleus . Sometimes comets smash

into planets or get burned by the sun. One well

know comet is Halley's comet which last came in

2003 and will come again  around 2061. I will be able

to see it ! Halley's comet is named after Edmund Halley

who found the orbit of the comet.  Comets orbit the sun.

They Come close to  it ( that is when we see them )

Then travel far far away like to the Oort cloud .

The solar station

My mom and brother and sister and I went to meet some friends at a nearby solar station which was run by the US government. Our friend was the captain and showed us around including the two telescopes with which we saw the sun it was very interesting he also showed us a PowerPoint presentation explaining important things about the sun and it's rays. I also really enjoyed drawing on their dry erase board with erase markers and drew a Roman and a Viking and had so much fun.
