Rabi‚ a physics professor at Columbia University‚ suggests a clock could be made from a technique he developed in the 1930’s called atomic beam magnetic resonance. 1949 Using Rabi’s technique‚ NIST (then the National Bureau of Standards) announces the world’s first atomic clock using the ammonia molecule as the source of vibrations. 1952 NIST announces the first atomic clock using cesium atoms as the vibration source. This clock is named NBS-1. 1954 NBS-1 is moved to NIST’s new laboratories

An investigation on the activation energy for the iodine clock reaction Introduction: The iodine clock reaction is a presentation of chemical kinetics‚ which are the elements that affect the rate of chemical reactions. When the two colorless solutions are incorporated together‚ no reaction can be spotted. But after a short period of time‚ the solution turns into a dark blue solution. The term rate of reaction is stated as the decrease in the concentration of one of the reactions or the increase

which non-rational or magical phenomena play a significant part’ (Manlove‚ 1975‚ 1). Following this definition‚ The Cuckoo clock would be classified as a fantasy by several elements in the story. To begin with‚ the story is based on the classic idea of a child communicating with animals or objects. In this case‚ that object would be the wooden cuckoo coming out of the clock. This idea itself is quite a common subject matter for children’s literature. For example in Little Princess‚ the little girl

The man counted them one-by-one until‚ on the final ring before he met his fate‚ “the clock collected in the tower its strength‚ and struck”. The clock’s strength refers most probably to how heavily it must ring. To the man‚ on that final quarter hour toll‚ it must have sounded as heavily as he had ever heard it. For‚ truly‚ it would be the

Death Clock: Stimulus B. In Greenview the Howth clock stood over the town like a guardian. ‘TICK TOCK TICK TOCK’ it went as it counted the hours‚ minutes and seconds of every day. On the outskirts was the Greenview forest which contained all the memories of our childhood‚ building forts and playing hide and go seek. On the other side of town led to the crusty salty ocean coast which cooled our hot sweaty bodies after a fun afternoon out exploring the forest. This was what life like was before…
