Why do students need graphing calculators to sit exams? My University specified a standard model for exams (I studied Physics), which they supplied during exams. You could buy one the same (cost was approximately $20, since it didn't do graphing or anything clever) if you wanted, but since all one needs is trig functions, perhaps some stats, and basic arithmetic. Everything else should likely be understood/remembered by the student since that's what exams are there to test.

If I could buy a car that got me to my destination without the time and hassle of requiring me to guide it and avoid traffic/bad drivers, then that would be a feature that I would value. So, if there is someone out there working on a car for people who hate driving, I'd like to encourage them to continue working on it. Do not be discouraged by the preceding poster.

Perhaps it could run on some sort of metal guides embedded in the road. You could then create a network of these guides and maybe even share the vehicle with others -- perhaps the city could own them and the infrastructure and you could just pay when you need to use it?

lol I feel sorry for anyone who has to go through a body scanner or who is singled out for a search (having gone through many, since I often travel with weird prototypes), the girl in that movie keeps saying, "all I was doing was asking questions." Totally reminds me of this.

Heh. Makes me think of this XKCD

When I completed my science degree at university a few years ago, the calculator for exams was supplied by the university. The whole university standardised on one calculator for exams, published the model at the start of the course and kept a couple of hundred in storage for use only during exams. Oh, and ban any other type of electronic gizmo (our foreign-speaking students were allowed a paper dictionary only, and perhaps a few more minutes at the end to make up for the time they may have spent looking up words).

In order to apply coordinates to these maps, coordinates that are usable for anything other then simple viewing, you will have to find some way of morphing a grid with coordinates across the images you have after scanning. It might be something as simple as creating a transparent layer in Photoshop that can be stretched to align properly. My guess is that you would need some sort of custom plug-in for this to deal with the various projections used on the map images. Scaling shouldn't be an issue unless it is inconsistent and changes across the image.

Any graphics whizzes out there that can expand on this?

Even inconsistent scaling shouldn't be a problem. The company I work for sells PIV software (to measure fluid flows) and that has a dewarping algorithm which can correct for distortions caused by curved windows and off-plane camera alignment. I'm pretty sure that something like it could be applied to an old map that has incorrectly positioned features to bring them onto a sensibly shaped square grid for geocoding.

Entropy isn't what it used to be.

Working...
