I bought an old mountain bike with the idea of refurbishing it into a commuter.

When shifting, the chain only goes to the middle and smaller gears of the cassettte. Won't go into the lower gears. Trying to figure out what the issue is. Could it be the lower limit screw needs adjusting? Any suggestions?

I am signed up for a wheelbuilding class at my LBS. I would like to build a front wheel that has a dynamo hub. Any suggestions as to which model is good quality. The bike (a mountain bike that I use as a commuter) has rim brakes, 26" wheel, 32h.

Thanks

On my commute this morning, my bike acted like it wanted to shift on it's own - totally annoying. It's a mountain bike (GT Avalanche) that I modified for commuting. Other than this problem the bike is great.

I've heard this called ghost shifting by a bike mechanic. Does anyone know what adjustment to make to correct this?

Can someone tell me what a hipster is? Wikipedia is too vague.

I'm middle age by the way.

Regarding the seat post, what is the minimum engagement length? I'm a taller rider and generally have the seat up high. I was wondering at what point I need to get a longer post.

800*tan(theta) -14.835 / (cos(theta))^2 = 0

I know the answer is about 1.06 degrees because I used the solver function on my HP, but how would it be solved algebraically?

Is there some trig identity I am missing?

Thanks

I prefer to use honey instead of sugar when baking because I understand honey is better for you. So if a recipe calls for a cup of sugar, how much honey would I use?

Do phone jammers work if someone is texting, like in a movie theater?

I haven't been able to use this mask because I can't seem to fall asleep with it on. Does anyone have any suggestions?

I have heard about the the nose pillow option.

Were the US military leaders not aware that the discension between the two countries would likely provoke an offensive by Japan?

It seems like the military leaders were asleep at the wheel.

Is it OK to put a cigarette lighter in luggage which will be checked?

Does anybody know the name of the DVD of this guy artist that makes art out of flowers, rocks, branches. I think he's English. The video is fascinating, I saw it years ago but can't remember the name of it.

I have to take a "high level programming language" as a prerequisite for a math course.

Which is easier to learn?

Do you have to know C before you can take C++?

I've taken Fortran and Pascal and I picked it up OK, however I never do much programming for my job so I essesntially forget most of what I learned.

I understand the use for binary, as everything can be written in terms of 0 or 1, which makes computing efficient. But why is there hex and octal?

Does anyone know how to extract a jpeg from a video file?

I tried playing the video and then hit Print Screen and pasteing the screen shot into Paint but it did not take.

I have a graduate math course coming up that requires a knowledge of Matlab. Does anybody know of a course or tutorial where I can learn this software?

Has anybody out there had a class in abstract algebra? It is one of the options I have for next semester in grad school math. What is the class like? Is it one of the more difficult courses?

I have this major crush on the receptionist at my dentist's office. I don't really know her well at all, she's just very nice and extra cute. I think she is not married as I do not see a ring.

How do I approach her about going out? Usually when I sign in at the office there is always someone else around, so it could be kind of awkward to ask her for a date.

This question is primarily addressed to people that have completed an MS in Math. I would like some advice.

I am starting my MS in Math next fall. I'm an engineer by profession but have decided I want to teach junior college math, therefore I need a graduate math degree.

I loved the math required for my BS and MS engineering degrees because I could see the direct application of it. From what I understand, a graduate math degree requires several courses in theoretical math like topology which involve solving proofs. I was never very good at this, in fact I barely got through high school geometry. Is there a course or something I could take that would help me with this challenge?
