    Biomedical Engineering and Biotechnology

    What cities have large industries of Biomedical Engineering and Biotechnology. I've heard to look at the East and West Coasts. Does anyone have any more specific information? Thanks

    Different Number Systems

    I do not know a lot about math theory, however I know that we (America) (I'm not sure if it's different for different parts of the world) use a base 10 number system. I also know that there have been other number systems invented. Can number systems other than base 10 be more beneficial for...

    Modifying power source

    While this is certainly true (and certainly easier), I want to do it for the tinker factor and the knowledge. I would like to use this in a more complicated project later. Thanks a lot.

    Modifying power source

    I have a small electronic toy that takes 4 regular triple a batteries. I would like to open it up and see how much current the batteries are supplying, and then I would like to hook up a battery that I don't have to throw away. I would like to hook up the device to the wall to recharge it. I...

    Question regarding Sleeping

    I've noticed that I often wake about an hour or two before I should get up. When I awake, I often feel pretty energetic but I go back to sleep because of course, I have a couple more hours awaiting me. Then when I wake up the second time, I can feel "dead" or really tired. Does anyone know why...

    Camera-Computer Help

    I would like to create a small platform that connects to the parallel or usb port of a computer. I would like it to rotate it 360 degrees on an xy plane, and at least 180 degrees on a xz and xy plane. The platform would perhaps have a camera on it and I would like to control the movement of the...

    Question regarding sleeping

    My brother sleeps with one of his eyelids slightly open, allowing his eye to be exposed. It is really small (a sliver really). Has anyone heard about this? I'm also curious if it is harmful. On a sidenote, it's interesting to watch when he is in REM.

    Motional EMF in loop of wire

    " A circular loop of wire 10 cm in diameter is placed with its normal making an angle of 30 degrees with the direction of a uniform 0.50T magnetic field. The loop is "wobbled" so that its normal rotates in a cone about the field direction at the constant rate of 100rev/min; the angle between the...

    Videogame Programmer

    Well this is very interesting and I appreciate everyone's comments. I was just looking into it because I like to program and so I thought if I was programming games, that would be especially fun. I am majoring in Biomedical Engineering right now and several older students have told me that one...

    Calculating Shear Stress

    On a homework assignment where a device contains three pin connections, we are asked to find the shear stress on two of the pins ( single shear) and a third which is experiencing double shear. For the single shear, I just took the force being applied at the pin connection and divided it by the...

    Gap year

    When contemplating on whether or not to take a year off from school, I like to think of myself as a product of momentum. For one, I know that if I stop school, it will be hard to get back into it. It does sound like you are burning out, but who wouldn't after a course load like yours. Perhaps...

    Testing No. 2 pencils and scantron exams

    I love mechanical pencils but a good point was made in a book titled " Up Your Score: The Underground Guide to the SAT", that regular pencils have blunt tips that will require less time to fill in a scantron bubble. Perhaps true? Just thought I would throw that out and let your know that you're...

    How usefull are dc and ap classes in highschool

    Oh you are right that is a silly mistake on my part. I am a little confused and don't understand what you are writing (I'm not as advanced hehe) but after revision I get : -\omega^2\cos(\omega t) + 9\cos(\omega t) = 0 \cos(\omega t)(-\omega^2 + 9) = 0 So my solutions are still...

    Differential Equation and omega

    Thank you for pointing out my mistake. I am a little confused by your answer because we haven't talked about "homogenous equations", or had any solutions with imaginary numbers (3i). However would this be right... y = \cos(\omega t) \frac{dy}{dt} = -\omega\sin(\omega t)...

    Need some advice or opinions

    I would also agree that if you plan to go to grad school for biomedical engineering, you should major in it as well. It will make you more familiar with the field that you are going into. If you still want to do physics, perhaps minoring in that?

    Finger prints.

    I wonder if expression of our genetics has anything to do with how our fingerprints form. Perhaps then fingerprints are unique. Otherwise it does seem like two individuals having the same fingerprint is just "improbable" not "impossible".
