My science project is sciencespeak.It is talking about some words that have 2 or more mean for science.

= What is sciencespeak? =

We’ve all used sciencespeak at some point in our lives – oftenin our everyday speak. The likes of journalists and politiciansuse it frequently. Sometimes it’s misleading. Sometimes it givesan impression of superior knowledge. Other times it might justbe that these scientific phrases seem most appropriate.

More often than not they are words or phrases that have beenused so frequently in the English language that their newmeaning seems to have preceded the old. And these new meanings can often be far from the original… =// why some people always use some science words for wrong mean? //=

Because maybe those words are not cool,difficult to remember and produce.Clone and copy have got same mean.Clone have two mean.So when you say that ,some people should ask you what is that mean? You should feel good.

= Two examples about the science words =

**Quantum Leap or quantum jump**A classic example of misuse might be: ‘Any solution to the problem of global warming will require a quantum leap in the public understanding of what individuals, companies and governments can do to help’. The writer or speaker presumably means a ‘great change’, but thinks ‘quantum leap’ sounds better. But what does ‘quantum leap’ actually mean? The energy in any physical system (for example, an atom or molecule) can only exist in certain fixed energy levels. For this energy level to change, the system has to take in, or give out, a definite amount – a ‘quantum’ – of energy. The jump from one energy level to another is instantaneous – it can never happen gradually

Eclipse, eclipsed, eclipsingAnother example is ‘Eclipsed’, as in: ‘The older manufacturing industries have been totally eclipsed by the modern hi-tech ones’. What is meant, presumably, is that the older industries have been surpassed or made insignificant by the modern ones. But again, what does ‘eclipse’ mean? It is most commonly used in connection with heavenly bodies such as the sun and the moon, where one body gets in the way of the light from another. One obvious feature of a total eclipse of the sun is it never lasts for more than a few minutes.
