Water Powered Calculator


Water, water, every where, Nor any drop to drink

That often-misquoted phrase reminds us that not all water is potable - normally due to its high sodium content, incompatible pH level, and native plant and animal life. There are a myriad of treatment options available to you, but regardless of which one you chose, one thing is certain: you'll need math to figure it all out. And what better to help you with your calculations than a calculator. While you're at it, use water to power the calculator!

That's right - to get this calculator juiced up, just add water (regular tap or filtered water, only). A cap full of water in the H2O battery can power the calculator for up to 3 months. And this calculator isn't a wimpy, dinky thing; you get a full-function calculator with large keys and a large 12-digit display. A calculator is basic office gear, everyone needs one. Geek your calculator up a notch - make it water powered!

Does light have mass?

The short answer is "no", but it is a qualified "no" because there are odd ways of interpreting the question which could justify the answer "yes". Light is composed of photons so we could ask if the photon has mass. The answer is then definitely "no": The photon is a massless particle. According to theory it has energy and momentum but no mass and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons it was known that light carries momentum and will exert a pressure on a surface. This is not evidence that it has mass since momentum can exist without mass. [ For details see the Physics FAQ article What is the mass of the photon? ]. Sometimes people like to say that the photon does have mass because a photon has energy E = hf where h is Planck's constant and f is the frequency of the photon. Energy, they say, is equivalent to mass according to Einstein's famous formula E = m...
