Hello. What would you think of the international scientific community calling to change all negatively charged particles to positive and vice versa? Do you think there's a circumstance where we should switch or should have switched? The only reason I brought this up is that it came up when...

One thing I don't quite understand yet: Evaluating the approximation to these (with several bases) leads to a value that appears to always be less than using Ramanujan's method. For example: let n = 4 (where n is the base of powers under the radical) and you get: t^2-2t-1=0 t=1+\sqrt{2}...

I've made a nice little excel file to help study these. Interestingly, if you use 4 as a base, it seems to converge to exactly 2. It's the only number so far that I've seen do this. I've tried powers of 2 up to 2^16, and those appear non-rational so far. If anyone wishes to use it, you'll...

Thank you guys! It's a lead!

Good evening. Is there a way to take a decimal approximation and see if there is a relatively simple expression? I'm guessing there might be software for this, but I'm not sure I'm even asking the appropriate question. If it matters, the number I'm after is...

Thank you for all the posts here. I've decided the readings above one are probably from hysteresis, probably due to a difference in frequency of sampling temperature and mirror fogginess. The makers of the device (it's an Aqualab 4) could assume that people would only use the result at a stable...

Good evening. I recently was taught how to use our new water activity meter, and I noticed something strange. This meter uses changes in the reflectance of a mirror. Whenever we'd bring the sample up to temperature, the measurement would reach a low point, then at about 0.5° below our set...

There are usually a lot less consumers, heterotrophs, than producers, autotrophs, because a portion of the energy will always be lost with each transfer. Some of it will be due to heat loss while other parts will be due the energy required to digest and process the producer.

Keep in mind too, just because you don't feel a shock or later detect a failure of the circuit does not mean you have not damaged it too. This of course depends on the properties of the electronics you're working on.

I went into the film with high expectations, and it more than satisfied me. The story was very well written, and the acting was quite compelling yet natural. The visual effects were absolutely beautiful too. I must now find a way to implement gravitational lensing into my ray tracer.

Wheels would be enormously different from current structure in place. How would you grow and maintain an axle? How would you prevent infection there? Any steps on the way to making them would probably be non-functional, and wheels would probably be less agile than limbs for most terrain.

Humans can actually see UV light, but you have to lack a lens to do so. http://en.wikipedia.org/wiki/Aphakia

Additionally, skeletal muscles must expend energy to maintain a force even if no work is performed as it takes energy to keep setting filaments into the contracted state. See the paragraphs under "Comparison of Smooth Muscle Contraction and Skeletal Muscle Contraction"...

Sorry to link to wikipedia, but you may be interested in TREE(3), and I can't find too much info on it. A is the Ackermann function. http://en.wikipedia.org/wiki/Kruskal%27s_tree_theorem

I had some sloppiness problems with my algebra when I left high school. I don't know if the same causes yours, but one thing that helped me was writing my problems out more neatly in addition to the suggestions above. I thanked myself a lot once my more advanced classes came around.
