The dumb questions thread

 
 
 
Hmm. I'd prefer all numbers or all letters. Mixing the two doesn't fit my purpose. Is there free software that spells huge numbers out? I don't see it in my apps store. Thank you by the way.
 
the reason for the plus sign is because it is perfectly valid to have a negative sign.. and just like in any other system, absence of the sign implies a positive value. Scientists don't like assumptions so much, so for completeness and consistence, the + sign is sometimes used.

While 1e+24 is 1 septillion, 1e-24 would be 1 spetillionith (0.0000000000000000000000001)

I prefer 1e-24 or 1e+24
 
Question:

Why does a helicopter flying overhead disrupt my FM radio signal?
 
after taking a shower, with I ever encounter one of those water molecules again?

Total water on Earth: 1,386,000,000 km^3.

More reasonable units: 1.386E+9 km^3 => 1.386E+18 m^3.

Assuming it's pure water at maximum density: 1.386E+24 g.

Nuclear particles per gram: 6.022E+23. Nuclear particles per water molecule: 18. Water molecules per gram: 3.34E+22

Water molecules on Earth: 4.47E+45

Typical shower: 65 liters => 6.5E+4 g => 2.171E+27 water molecules per shower.

You have 2.171E+27 chances to draw one of 2.171E+27 molecules. 4.71E+54 >>> 4.47E+45, assuming perfect mixing the odds are effectively 100% that you'll see one of those molecules in your very next shower. (In practice the mixing won't be anything like perfect so you'll probably have to wait a bit to encounter one.)

The imperfect mixing only makes the chance of encountering one in his next shower even more likely. The 2.171E+27 water molecules he used last time aren't randomly chosen molecules; they're molecules selected for being very close to his shower. Which is to say, the water molecules from his last shower didn't all go down the drain. Some of them were adsorbed into the surface layer of his bar of soap; some of those are coming out in the next shower.

I was hoping it would be obvious that I meant the water that went into the drain. I suppose it makes a huge difference if I have a septic tank or city sewer. I was assuming in the example city sewer. Water eventually discharged into the Cuyahoga River, then into Lake Erie, then in to the air.

But how much of it went over Niagara Falls & into Lake Ontario & down St Lawrence into the Atlantic?

We're looking into that. A lot of people are saying there's a tremendous - HUGE - amount of water doing that. I don't know, but that's what people are saying. Good people, fantastic people. And they're saying there's an extreme amount of water doing that. But I can tell you one thing; I'm going to fix it!

And make Niagara Falls GREAT again?

Well yeah... which is why I asked the general question. How much goes into the air, how much stays in the GL system for a while? And it may vary based on where in the GL basin you live. If you drain to Lake Superior, it can take water a very long time to leave that lake.

How many times will you interact with the same molecule? To really mess with people's minds, how many people have drank that molecule over the past 5000 years?
