The incompressibility of most liquids.
The idea behind the hydraulic press (machine or bench press) is that a liquid, when displaced, will exert pressure or force equally across the surface it is forced against. Because of this, hydraulic presses are commonly used for automotive and industrial repair shops, where pressing, bending, straightening, and forming is required.
A hydraulic systems works on the idea that, unlike gasses, liquids cannot be compressed. By using this idea you can set up a system that transfers pressure through liquid to aid in the lifting of an object. One great example of this at work is the breaks in your car. When you put down your foot on the breaks you exert....lets say 100N (Newton's) of force, the shaft which this force travels down would be about 4-5 cm in diameter, because the force traveling through liquid loses no energy, when the force reaches the actual pad on the wheel which has a surface area of (say) 20cm, it will exert 500N of force (force*area....5*100), which will inevitably stop the car. Initially the hydraulic system relied on water to transfer the force between the two areas, but once the true potential of this system was realized, companies set about to develop a special type of hydraulic liquid that was a poor conductor and help to reduce friction.
His knowledge surpassed simple machines. He conceptualised a helicopter, a tank, concentrated solar power and a calculator; to name but a few. Most people today would not have the faintest idea how a helicopter works and as for solar power, electricity had not even been invented yet and Da Vinci already had ideas for it.
Please refer to the link http://en.wikipedia.org/wiki/Pharmacogenetics to give you a basic idea how genetics helps in the manufacture of drugs and understanding the drug response.
Level sensors are designed to detect the level of substances that flow. The idea behind a water level sensor is that it can detect the level of water in any given scenario.

It is an artistic failure.
The rule of law is the principle that all individuals and institutions, including government, are subject to and accountable to law. It ensures fairness, equality, and justice by providing a framework for governing and resolving disputes based on established laws and procedures. This concept promotes transparency, predictability, and the protection of individual rights within a legal system.

The idea behind a virtual fax is to enable business to send email faxes without the use of a fax machine. This helps to reduce the cost for fax machines, fax services and long distance fees.

The basic idea behind a refrigerator is very simple: It uses the evaporation of a liquid to absorb heat.
deviance arises not so much from what people do as how others respond to what they do
The ideo behind the manual Classroom Instruction That Works is to provide teachers and future teacher a basic guideline for activities to use in the classroom.
