 Christina from England asked;
How many different kinds of science are there e.g phyisics
 NOISEmaker Andrew Russell answered;
This is an interesting question and there's probably a few ways of answering it. So here goes... In the past, the term "science" simply meant knowledge and the ancient greeks, who were some of the first people to think about science as we would understand it, wouldn't have made distinctions between disciplines as we do. They would have just referred to natural philosophy i.e. knowledge of the natural world. Obviously at school when you study science it is split into physics (the science of matter), chemistry (the composition of matter) and biology (life science). There's problems with dividing science like this, though, as there are significant overlaps between physics, chemistry and biology that blur the division. It is also difficult to incorporate maths into this system of division and maths is fundamental to doing science. We also need to consider that a lot of scientific research these days requires expertise in more than one type of science so dividing science up can make some kind of work more difficult to get done! My thinking on this subject is that I try to understand as much science as possible and to describe myself as a scientist with a specialisation in something quite specific (I'm a dynamical meteorologist, which means that I study how small weather systems begin). This does, however, mean that there would be hundreds, if not thousands, of different kinds of science. Have a look at this page from Wikipedia for an idea: http://en.wikipedia.org/wiki/Fields_of_science I hope this helps!

Corretta from U.S. asked;
How do you determine the acceleration and distance traveled by an accelerated car.
NOISEmaker Emma Carter answered;
Speed (or velocity which is speed in a certain direction) is the distance travelled per unit of time (e.g. m/s). Acceleration is defined as the rate of change in speed (e.g. m/s/s). To work out the acceleration and distance travelled you use these equations: acceleration, a = (v2 - v1)/t in other words, a = the change in velocity divided by the time interval For a car travelling at a constant velocity (v), the distance travelled = v x t which is the velocity multiplied by the time interval. For a car travelling with a constant acceleration, a: distance travelled = (v1 x t) + (a x t x t)/2 where v1 is the initial velocity is the time interval.

tasha from jamaica asked;
can noise be classified as pollution
NOISEmaker Emma Carter answered;
Yes! Noise pollution can be defined as 'environmental noise that is annoying, distracting, or physically harmful'.

Stanley from London asked;
Hi NoiseMaker, I am an A level student studying Math, Physics, Design Technology & Business. What i need help in doing is getting an internship for the Summer 08 i want to get an internship preferably with Sony/BT etc In electrical & electronics engineering...any help??? i've tried everywhere..
NOISEmaker Philip Jess answered;
Hi, I had a look at the BT and Sony websites and they do have internship programmes but they tend to be for university students, however there is no harm in applying for them. The best thing to do would be to write formal letters typed, then signed and posted (don't send emails) to human resources departments in the companies you are interested in explaining your situation and why you would be a good temporary addition to their workforce i.e. your are enthusiatic, hard working, keen to learn etc. There may be no specific positions available but if you impress them they may help you out. Next, don't limit yourself to just a couple of companies, there are lots of firms out there that do electrical engineering so shop around and increase your chances of getting something, for instance BAE systems definately have a programme for school leavers and there are lots of computer and communications companies out there. If you cant get people to answer your letters pick up the phone and call human resources so they cant fob you off. Finally there is also the possibility of doing electrical engineering research in a university environment over the summer. The Nuffield foundation provide school pupils grants to go and work in a research egroup so you can see what it's all about. Hope that all helps, I've pasted some links below that may help in your search and good luck with it, hope you manage to find something.

Emily from Leeds asked;
Hi, I'm currently doing a project trying to make science (in particular biology) appeal to 14-19 year olds through an as campaign. do you have any ideas what would make science appeal to this target audience. and any ideas wy it is becoming so unpopular nowadays?
Thanks
