Respiratory System - AJ

• The respiratory system is the system in your body that is responsible for the motion of breathing in oxygen and exhaling carbon Dioxide. The very prime organs of our Respiratory system is our lungs because they are the organs that exchanges between carbon dioxide and oxygen.
•  Also in the respiratory system the red blond cells take the oxygen from the lungs all the through to the rest of the body, during this process the Red blood cells take the carbon dioxide to the Lungs so it could be emptied when we exhale.
• The human body needs enough oxygen to sustain it's self. When there is a decrease of oxygen in a human body it is known as  hypoxia, but when there is a complete lack of oxygen the human body then it is called anoxia and these conditions can be fatal. When your body is without oxygen for 4 minutes then, your brain cells start dying and when most of them have died then the body will stop functioning and die.
• In humans, the average rate upon breathing is based on age. A newborn's normal breathing rate is 40 times a minute and about 20 to 40 times when they are sleeping. For adults, the average breathing rate when they are resting is at about 12 to 16 times a minute, and the healthy adults breathe 40 to 45 times a minute when they are exercising. 
• As we breathe, oxygen enters through the the nose or mouth and passes the  sinuses, which are hollow spaces in the human skull. The trachea, also called as the wind pipe filters all the the air that enters the body.

Computer Programing - AJ

• Computer Programming  is telling a  computer to do something by giving it instructions, and these instructions are called programs. These instructions can all come in different languages, they are all called programming languages. Sometimes special programmers use special software called IDEs, which have many features that help them to make programs, and use simpler software.
• A compiler is a programs that is a set of instructions for any computer to follow. Making these instructions in computer would be called pretty difficult, so instructions are written in a simpler language that is pretty much like English so the computer can follow them.
• A compiler is also what we call a half English translator to the computer language. Some languages, called interpreted languages, use interpreters instead of compilers. A variable is a piece of the program that can be changed. Variables can include information added by the user, or answers that are found as a result of a calculation.
• Conditionals are parts of the program that work if something about the program is true. If that part is not true, then the program won't have it work. A common way for a conditional to be done is with an "If Statement."Here is an example of an if statement in the Perl programming language. What it does is it checks to see if the name variable is Bill. If the name variable is Bill, then it will print out the words "Hi Bill!"
•  Executables - Once a program is has been compiled, the instructions in "machine form" are written into a file that contains a series of numbers that the computer can understand. These files are generally called "executables". These machine-instructions will be loaded into thecomputer's memory so that the CPU can run them when the executable is opened. In the event that data is not transferred correctly, it can result in Data loss.
  
   

How Daylight savings Work - Navo

• According to astronomers, the big bang created both time and space about 14 billion years ago. Ever since, seconds and minutes have spooled outward, like an infinitely large ball of twine unraveling as it rolls on a ceaseless journey. 
• Humans have long tried to affect this unraveling process, to make it happen more slowly or quickly. Einsten even predicted it was possible, if we could travel at the speed of light.
• Humans have devised ways to manipulate it to their advantage. Daylight saving time (DST), the period of year when clocks are moved one hour ahead to create more sunlit hours in the evening, stands as one of the best examples of how this can be done.
• Benjamin Franklin first conceived of DST in 1784, while serving as U.S. ambassador to France. According to the story, he woke one day at 6 a.m. and noticed how many of his fellow Parisians were still in bed, with shutters drawn to keep out the light. 
• As a result, people were sleeping during sunlit hours and burning candles longer into the evening. 
• The United States follows rules established by the Energy Policy Act of 2005. According to that legislation, daylight saving time begins in the U.S. (a country in the Northern Hemisphere) at 2 a.m. on the second Sunday in March. That's when many Americans move clocks forward by one hour and, if they're diligent citizens, replace their smoke-detector batteries. It ends about eight months later; at 2 a.m. on the first Sunday in November, clocks move back an hour, and standard time reigns again.

Big Ben - AJ

• Big Ben is a famous nickname for a big bell that rings at the clock tower, it is also located in Westminster, London, England. Officially, the tower itself was named the Elizabeth tower and it was named after the famous ruler of London, Queen Elizabeth, but before that it was named as the clock tower. Its most popular name was Big ben because it's huge size and it had weighed at about 13 tons that is 26,000 pounds! 
•  Big Ben is now currently the biggest four faced chiming clock in the world. The Big Ben cock tower has became one of England's most memorable landmarks and it also has an establishing shot of films.
• Many people in London, England  believe that it had gotten it's  name from sir Benjamin Hall. The clock alone in the tower had weighed around 5.8 Tons and that is about 11,000 pounds for a clock. It took 13 years to build the Big Ben, at it is Roughly at about 16 stories high.
• The people of London had named this bell, supposedly the big bell was going to be named Victoria after the queen Victoria, but as years people came up the name form as Big Ben it was finally made as it's new name.
• When are at the Big Ben clock tower you could feel it's vibrations moving from your head to your toes. In England instead of just making it their governments property they make it all of England's property, but must pay extra taxes for it.

What is Inertia? - Navo

• Inertia is, in physics, the resistance of a body to any change in its state of motion, it is the resistance of a body at rest to being set in motion or of a body in motion to any change of speed or change in direction of motion. Inertia is a property common to all matter. This was first observed by Galileo and restated by Newton as his first law of motion, sometimes called the law of inertia. 

• Newton's second law of motion says that the external force required to affect the motion of a body is proportional to that acceleration. This, The constant of proportionality is known as the mass, which is the numerical value of the inertia; the greater the inertia of a body, the less is its acceleration for a given applied force. 

• In Inertia a moving objects means that an object that is moving in a straight line at constant speed will continue to move in the same direction and with the same speed unless an external force is applied to it.  

• The result of applying a force to an object in uniform motion, depending on the direction of the force applied, will be to change the speed, or direction of movement, or both. For Example, If a ball is still and you kicked it that is inertia and it is still moving that is Inertia. Inertia happens in everyday of your life.

How Robotics works - Navo

• Human beings are made up of five major components:
•  body structure, A muscle system to move the body structure,  A sensory system that receives information about the body and the surrounding environment,  
• A power source to activate the muscles and sensors,  
A brain system that processes sensory information and tells the muscles what to do.

• A robot is made up of the very same components. A typical robot has a movable physical structure, a motor of some sort, a sensor system, a power supply and a computer "brain" that controls all of these elements. Essentially, robots are man-made versions of animal life -- they are machines that replicate human and animal behavior.
• The vast majority of robots do have several qualities in common. First of all, almost all robots have a movable body. Some only have motorized wheels, and others have dozens of movable segments, typically made of metal or plastic. Like the bones in your body, the individual segments are connected together with joints.
• The robot's computer controls everything attached to the circuit. To move the robot, the computer switches on all the necessary motors and valves. Most robots are re-programmable to change the robot's behavior, you simply write a new program to its computer.
