True! :biggrin: At the time Darwin was developing his ideas about evolution another biologist called, Alfred Wallace was having the same thoughts and was developing the same theories. I'm not saying Wallace is the world's most unappreciated figure, but Darwin apparently got all the credit.

Hey all, I'm currently confused of what to study in college. I'm thinking about two options, Physics or Electrical Engineering. Anyway, what physics classes will I be taking, I know electricity and magnetism, but will I be taking quantum or particle physics or even relativity? And could...

Too bad, I can't take the test! I've read the article before. Here it is if you're interested: http://www.sciam.com/article.cfm?chanID=sa006&colID=1&articleID=0009F0CA-C523-1213-852383414B7F0147

Hopefully an astrophysicist! :wink: :approve:

About M.Sc in Physics, it depends on the instution. Most UK universities offer one-year programs after finishing a 3-year B.Sc course.

Same here! :smile: A Brief History of Time is a good book. The best thing for me was, in the beginnings, is googling the internet.

Pretty much most of the universities are switching from aeronautical to aerospace with a minor focus on spacecraft designs. Some of course offer Astronautics courses which concentrate on spacecraft industry.

Classical mechanics is Newton's mechanics. Anyway, they sometimes say you need a good telescope to be a good astronomer and good mathematical skills to be an astrophysicist :wink:

Have you tried thinking of it by yourself? A lot of actions around you involve both. I'll give you an example; firing a bullet from a rifle.

Emf = V(terminals) + V(lost) You actually don't need to.. First, short circuit the battery to find its emf. Set up your circuit with the variable resistor, voltmeter and ammeter connected properly. Now increase the resistance by moving the slide and record 5 reading for voltage and current...

JoakimvE, Hey it's simple. What are the steps of the experiment you're conducting to find internal R? Are you using a variable resistor or only adding resistors to the circuit?

Not really favourless.. Sometimes it depends on the type of seaweed you're eating. Just add some lemon and garlic and it'll taste great! :wink:

Yes, you can produce a magnet from steel by stroking its surface with a magnet or ferrous material. This will allign the domains of surface - they were first randomly ordered - in one direction producing an ordered magnetic field around the steel knife.

I'd rather think of it as only x=0, as "infinity" isn't a well defined number or digit..

In case you don't know - Stefan's constant is equal to 5.67x10^-8 Wm^-2K^-4
