Ah it was something interesting I quickly skimmed, and pardon me for a mistake since chemistry isn't my forte, and I haven't taken the required chemistry courses for my major yet. I probably misheard what somebody said on this. What I should've said is that pure water is a bad conductor. Whatever the case is, I found that the conductivity of pure water is 1/(1x10^6) of that of sea water. At that point wouldn't the current there be considered negligible since it's a very small amount (lim x->00 of 1/x=0)?


Thought that was indeterminate, rather than 0..?

Generally for something to be indeterminate we would have to have a limit that produces a 0/0 or a plus or minus (00)/(00). That can be solved with algebraic simplification of the function or use of L'hopital's rule. What I have is the 1/(00) while evaluating the limit, and that has an answer.

I was using 00 as infinity. While I'm here I might as well do a quick proof.

1/100 = .01
1/1000 = .001
1/100000 = 1x10^(-5)
1/1000000 = 1x10^(-6)

What do we notice? As we keep going, the value is getting smaller and smaller and is approaching zero as x approaches infinity. And this is why we say lim x-> 00 of 1/x = 0. This is very basic calculus and should be remembered. Many pages back in this thread, I derived escape speed from a planet. If what I presented wasn't true, then I'd be stuck on the proof.

Keep in mind, if I just wrote 1/(00), that would be undefined.

Oh. 00 to me does not look like infinity (in fact, it actually is not and is simply 0 as far as I'm aware). If it was clear you were meaning infinity then I understand completely. To me though, 00 is the same as 0 as it actually isn't an infinitysymbol.

I thought itwas possible to get infinity symbols on the forums anyway, so if so, why not just use that instead to eliminate anyambiguity?

I don't think there is an infinity symbol on the forums. If there is one, you can gladly show it to me. If I knew how to use an infinity symbol, I would've used it. Not to be rude or anything, but that question is just superfluous.

I would post something about science, but I'm in a rush.

I read from an article awhile back that there is research being put into an aluminum ion battery. The battery charges faster than a lithium ion battery and is less explosive than a lithium ion battery as well. The downside however is that the aluminum ion battery can't do as much work as the lithium ion battery, so that means less voltage. If I remember correctly, the voltage of a battery is W (work done by chemicals) / q (elementary charge 1.6 x 10^(-19) C). Make RuneScape Great Again usually on at 3:00 PM PST

Flying to west or east.
You are moving fast through several time zones.
You have your own inner clock.
The majority feels the way home that the time is running faster.
Let's say you fly from USA to New Zealand and the time different is ~24 hours.
You fly west in the map and then reach New Zealand in ''some hours'' and you are in a different place with +24 hours. What if flying east to Autralia from USA? The travel time may be much more but the time zone is the same.
The earth is round as a ball and taking the shortest path saves much time.
What if crossing the frontier that is -24 hours and +24 hours?
This is interesting.
Below is the round earth with time zone in hours different between USA and New Zealand:

l -12 l....West.......+0..........East....l +12 l -12 l.................+0................

Readed a recent new about a fish in Australia that starts to climb up to land and can survive without water for 6 days! Saw a video too and the fish could splash and move in paths in land.
How many much more do you want?

And... About Pokemon now!
(Adult Pokemon lover here! Don't blame me!)

To begin with, most of you already knows what Pokemon is.
Skipping the details to tell about it. Google is helpfully :D

Pokemon in games, Game Boy, Nintendo DS and more...

There is alot of MATH formulas in these games for like everything!

That's very cool because the game creators maybe like maths? :D

Some examples:

IVs or Individual Values, bonus combat stats ranges from 0-31 in binary system. 11111 = 31.
This one is really cool idea from the creators!

A Pokemon can have a maximum of 510 EV or Effort Value. Up to 255 EV per stat. Every 4 EV = 1 bonus stat. 255 *V = 63 bonus stat rounded down.

All Pokemon's have a catch rate. The highest catch rate is 255 and is easiest to catch.
The formula affects by current Hit Points, type of Poke Ball (Master Ball has 255 catch rate), status condition.

Pokemon's Base stats are fixed stats from all the same kind of species that affects how strong or good that species will be.

In battles, there is a pure math damage formula that determinds of many things.

To find a ''shiny'' (rare different colored of same species) Pokemon, the chance is 1/8192.

There is many much more :P :P :P
