    Parts of an 'information' in phyiscs.

    From what I think, any physical value has at most 3 parts - 1)Orientation - Or more explicitly, the angle that it makes with axis of the Cartesian coordinate system. Transforming will not change this value. 2) Position - This is the translational stuff...exactly from which point to which...

    Finding work with a phyiscs bachelor in the US

    I know that over here it's not very common to quit school after receiving your bachelor and not continue for your master's degree, so your chances of finding suitable work with only a bachelor's degree are slim. What's it like in the US? I heard just having a bachelor's degree there is pretty...

    The Phyiscs of Air Hockey - Lifting up the puck

    I have this crazy idea to make an air hockey table out of some junk laying around the basement. Before I waste my time messing around with an old table and vacuum I figured I would brush up on my basic physics to figure some stuff out. Lets say we want to lift up a lightweight hockey puck...

    Calculating Speed of Human Eye Lens: f-stop = 4

    A human eyeball is about 2 cm long and the pupil has a maximum diameter of about 5 mm. What is the speed of this lens? f-stop = 2 cm / .5 cm f-stop = 4 is this it? I'm not sure if I found the right formula in my book thanks

    What is the role of computers in the field of physics?

    [SOLVED] Computational Phyiscs Can anyone tell me what computational physics is all about? I'm "into" computers in general and was planning on doing a computer science degree until my interest in physics turned me away from it. The idea of a career that includes both computers and physics would...
