Usualy after i get home from class I spend majority of my time working on my robot playing halo or hanging out with my girlfriend. Although sometimes when I'm feeling extra ambitious Il spend my time learning about some of the more interesting/difficult parts of math and physics.

What do you guys think of Arduino? I have been using to build little autonomous robots and it seems to work pretty well other than storage and voltage limitations. Is there anything better i could upgrade to or should i just stick with it?

It works! Thank you all

Today I learned that in order to make an electromagnet i must insulate my wire [emoji23]

Ok i get it so i could say wrap the wire in electrical tape and then coil it and it should work

I got the copper wire from an old T.V. Where it was used in an inductor

No its not

In my adventures through my attempt at a home laboratory i decided i would try to play with electricity a bit more. I took an iron cylinder 1 inch diameter 6 inch length and wrapped about 4 meters of 1mm copper wire around it with a small length hanging off each side. To my understanding...

thank you i understand now

Question: If cosθ=(3/5) and 0<θ<2pi determine the value of sin[θ+(pi/6)] Attempt: θ=cos^-1(3/5) θ=0.927295218 sin[θ+(pi/6)]=0.992820323 real answer = 0.992820323, -0.39282 How do i find the second value, all i can find is 0.992820323 but not -0.39282

I disagree, it would not be useless at all. Think of a situation where you are rolling down a hill and don't have your foot on the gas or brake, your car would be moving due to kinetic energy from potential energy. Obviously the wheels would be spinning resulting the the belt spinning and energy...

I took a look at Ehrenfest paradox and the radius is still confusing me. If the circumference changes due to SR why can we not say that C=2piR and C'=2piR' so R does not = R'
