I've never taken any biology courses, so this is kind of a shot in the dark.

Obviously there are more than one, but do we know Any biological, neurological processes that can be put in terms of a mathematical function? I know that there are different types of systems in the nervous system... i'm just wondering what determines the output given the input, in other words what happens to the action potential as it travels through an individual neuron. Perhaps they've measured such in individual giant squid neurons?

With over 100 billion neurons, i can't imagine the process needs to be too significant in order to achieve emergence, yet i really have no idea what types of processes can turn raw data into sensation, perception, and awareness...

Thanks!

Only the kitchen sink line is froze. I have a no flow situation. Can physics help?

I don't understand why only the kitchen sink line (neighbors also). It's been extremely cold in the midwest.

Will a fish tank heater in the iron 5 inch pipe have enough watts to melt it? It's frozen in the 5 inch pipe that runs under the cement slab of the house.

Boiling water just makes the PVC pipes seals melt and leak.
Would sidewalk salt help? Is there a concern with the HCI (industrial drain stuff) that is still in the pipes and the sidewalk salt? Is there another chemical I can add?
Any information or ideas would be appreciated......

When the sun is dead, gone, burned out, or however you'd like to put it, what is going to happen to earth and the other planets.? Well they still be pulled by the sun's gravity, or will they just fly off course?

As per the Krishnamurty Paddhati, while making any prediction for any event, in horary astrology, we calculate the significators for the concerned cusps. If the number of the significators are large, we sort the fruitful significators with the help of ruling planets, rejecting the planets which are in the star or sub of a retrograde planet. Since there can be a position of planets in which all the planets (i can support it by a chart) are in the star or sub of a retrograde planet, then going by the basic definition of K.P., the event should not materialise. But the said event has materialised. How to make predictions in such cases or how does the retrogression of a planet exactly function

"Solve for each exponential equation. If an answer is not exact, give the answer to four decimal places."

1) 4^x+2 - 4^x = 15

2) 3^x+3 +3^x = 84

the 1st problem is supposed to be "x=1," cause it says so in the back of the book. I tried using logs to get rid of exponentials in x+2 and x, but I got a negative decimal. Help?

my idea is about high-speed space travel. currently, it takes years for our space probed to reach objects within our solar system. this is too long. if we went faster, it would take less time to get there. so why don't we go faster? because we're limited to what we bring with us as far as feul, weight, etc. so I thought of a way to make better use of the fuel that we can already bring into orbit. it requires very complex engineering but it should work.
let's say we launch a space ship(probe) into orbit. after escaping earth's gravity there is a limited supply of fuel left to provide the thrust which will propell the probe to regions of space. say that amount of fuel is a million gallons. this number does not reflect the needed fuel for slowing down or the return trip. so we have a million gallons of fuel that we'll use to accelerate to our cruising speed. so we put the pedal to the metal until we burn all that fuel. let's say that process takes a day. so for 1 day we're accelerating
