Best, Cheap Technology for a Science Classroom

Hey MeFites, I'm really trying to expand the use of digital technology in my classroom. Unfortunately, the resources at my school are fairly limited. However, I do have access to $1200 in grant money, assuming I can write a compelling enough proposal. Help me find some affordable tech for my classroom! Needs of class inside. [more inside]

How to respond to Mars exploration vs feed the hungry?

Today, I was enthusing about a photograph from the surface of Mars, and a friend responded along the following lines: "I find it hard to get excited about it when there are so many starving people here on Earth. We should fix our own problems before exploring other planets." How could I have responded? [more inside]

Why don't we have HD video of Earth rotating in space?

Why don't we have HD video of Earth rotating in space? You know, relatively close-up, as if the Enterprise had just dropped out of warp and the planet was being majestically introduced to the cinema audience. An extended, multiple pass/rotation exposure, so that it could be watched by appreciative viewers wanting to get a bit of perspective/peace. I imagine I would sit and gaze at this for extended periods. What are the technical limitations which have prevented this?

How can a science/tech graduate get work to help developing countries

I’m an undergraduate chemical engineering student about graduate next semester, trying to figure out what to do next. I’ve always been interested in global development issues, and I wanted to get ideas on how I could get involved in this area, possibly using my background in science/technology in a useful way.

Past performance is no guarantee of future results

I've noticed that most of what I read about science and technology is universally optimistic about the pace of knowledge (if not necessary its use). From tech journalists to science fiction writers everyone seems to believe that the possibilities of technology are boundless and the pace of scientific discovery is, if anything, accelerating and always will be. My question is: Is anyone credibly arguing the opposite? [more inside]

What ever became of James Burke's little spheres?

In the final episode of James Burke's "Connections", he describes a secret experiment mixing CuSO4 and NaOH, and the potential uses for the result. That was the late 1970s--I am curious what actually happened since then. [more inside]

If the internet were being recreated from scratch, what would you do to improve it?

I've been asked to research the viability of the launch of a new top-level domain (TLD) parallel to dot-com. Assuming the prospective domain owner wishes not to reduplicate the internet as it exists now merely with another extension, I'd like to ask: Let's say you could take what you know about how the internet works (indexing, monetization, traffic, web-mastering but also crowdsourcing, social networking, political organizing, personal publishing, microfunding, etc.) and for reasons purely fictional, the existing system was scrapped and being re-built from scratch, what would you do with that opportunity if you had it?

What are some 3D puzzles?

What are some activities that exercise visual or structural type thinking? Something to do with science, technology, or 3-dimensions preferred. I'm looking for puzzles, hobbies, or other activities that might be performed through an actual job that I'm just not aware of. As examples, auto-mechanics classes and memorizing anatomy books immediately comes to mind.

recommend me some sci/tech websites please

Which science and technology websites do you (the scientists and technologists) visit regularly, to keep up to date on your subjects? I am, preferably, looking for generalist sites which are either global or UK-centric, such as the New Scientist website. Websites which focus on (or have sections on) applied science (especially those with any connection to "appropriate technology") would be particularly relevant.

Offsetting sea level rise: An engineering idea of Biblical proportions

The seas are rising. Climate change has made it inevitable. I have a strange question... Assuming that world sea-level rises by 1 metre over the next hundred years - Would it be possible to cordon off a section of land, somewhere in the centre of a continent, and flood it to create an artificial ocean, thus reducing the consequences of the sea rise?

Suggestions for graduate studies in technology and society area

I am looking for cross-disciplinary graduate/phd course in web technology. More specifically, relating to societal use of web from a global perspective. My goal is to become an expert in use of web based technologies in developing countries (which involves computer use, censorship, etc.). So far, what I have found is STS (science, technology and society) which sounds perfect, but from what I have seen, tend to be more in the areas of applied sciences and engineering. Then there is basic CS programs which tend to be more technology than societal aspects. Does anyone have any thoughts, ideas, recommendations? [more inside]

I am looking for a quote from an article. The quote discussed how the current state of the art in technology usually became the metaphor for how we understand and describe the universe.
