The telescope’s invention is often pegged in 1608 with the award of a patent to Lippershey by the States-General, the name for parliament in the Netherlands. However, an Englishman, Thomas Harriott constructed an early, low-power version of the telescope and used it in August 1609 to observe the Moon, at the same time when Galileo presented a similar small instrument to the Venetian Senate. Galileo […]
Objectives: To study the properties and performance of cross-coupled inverting logic gates. To set up the gates in order to obtain an experience, in the same time able to understand the Bistable Flip-Flop. These circuits have been mostly replaced become a straightforward and effective design. These designs for applications including large dimension digital circuits. Although these circuits have been changed, they still have important use […]
The Scale of the Universe The Universe is very vast. Many unanswered questions of life lay hidden beneath this place so unfamiliar to our society. This mysterious dark sky that we are floating in is supposedly constantly expanding to no end. Is there an edge? Well apparently there is no center to this expansion nor is there a fixed scale we know of. It’s just […]
INTRODUCTION This experiment is based on investigating the coefficient of expansion of air using a simple laboratory set up; the stopper flask method, where pressure is constant throughout the experiment. The increase in volume of a gas is directly proportional its temperature increase and is expressed as a fractional changed in dimensions per unit temperature change. Air will easily expand when it is heated and […]
INTRODUCTION Cathode Ray Oscilloscope (CRO): An oscilloscope is easily the most useful instrument available for testing circuits because it allows you to see the signals at different points in the circuit. The best way of investigating an electronic system is to monitor signals at the input and output of each system block, checking that each block is operating as expected and is correctly linked to […]
Nuclear physics is the field of physics that studies the building blocks and interactions of atomic nuclei. The most commonly known applications of nuclear physics are nuclear power and nuclear weapons, but the research has provided wider applications, including those in medicine (nuclear medicine, magnetic resonance imaging), materials engineering (ion implantation) and archaeology (radiocarbon dating). The field of particle physics evolved out of nuclear physics […]
INTRODUCTION In this experiment you will experimentally determine the quantum nature of charge. Robert Millikan was awarded the Nobel Prize in physics in 1923 for the oil drop experiment. A simplistic schematic of his apparatus is shown below A spherical drop of oil, falling through a viscous medium like air, will quickly reach a constant velocity. When it reaches this equilibrium position, the viscous force […]
CHAPTER NO: 1 MICROWAVE MOTION DETECTOR (MMD) 1.1 INTRODUCTION: “The Microwave Motion Detector (MMD) is a true microwave Doppler transmitter and receiver, solves difficult detection problems easily with the microwave motion detector, senses any moving body – be it a person, animal, car, bicycle or extra-terrestrial.” 1.2 WHY MICROWAVE MOTION DETECTOR: Understanding basic home security best practices could mean the difference between keeping your home […]
ACKNOWLEDGEMENT: History of all great works in to witness that no great work was ever done without either active or passive support of a person ‘surrounding and one’s close quarters. Thus is it not hard to conclude how active assistance from senior could positively impact the execution of a project .I am highly thankful to our learned faculty for her active guidance throughout the completion […]
Was it an asteroid that killed the dinosaurs? The extinction of the dinosaurs started in the cretaceous period, around 65 million years ago, and caused the loss of up to 70% of all life on earth. The way in which the dinosaurs died is a much argued topic which can be explained by a lot of theories one of which is the Asteroid theory. The […]
