Yea, but then it wouldn't be water anymore.

THAT is an accurate way of expressing it. Finally.

The point is, bonehead, that the "bucket of water" example has nothing
whatsoever to do with woodworking, dust collection, dust explosions, or
anything else even remotely relevant.

Obviously, I cannot state, with certainty, the chances of anything
bursting into flame. Nor can you. Conversely, you cannot state, with
certainty, that something will "never" burst into flame.
It's not a question of flammability but of precision in meaning.

Apparently, bonehead, you think that the laws of physics are just
suggestions. There are all sorts of certainties. Water not bursting
into flame in your shop is one of them.

If you don't get the connection of that illustration to woodworking
and the myth of the exploding home shop dust collection system, then

Starting off with name calling I see. That just shows the strength (or lack

is GUS, that there are some things that can be said with 100% certainty and
the bucket of water was an example. Unless the laws of physics are
different in your world, water in its liquid state cannot burn so there is a
100% certanity that a bucket of water sitting in your garage WILL NOT burst

Sure I can. If you actually studied a few facts, you could as well.

I guess that the laws of physics don't apply in your world or are you trying
to justify this crap with the chaos theory of variables. The fact is that
many of these variables are so rare that they become statistically
insignificant and are treated as non-existent. Simple facts say clearly
that a bucket of WATER will never burst into flames and if something were to
contaminate it and make it flammable, then it is no longer just a bucket of
water now, is it? The same can be said for explosions in a home shop dust
collection system. The mixture and conditions simply are not there to cause
an explosion and if you introduce variables that don't exist in a normal
home shop, then you are not dealing with a home shop dust collection system
anymore.

Actually, that is not precisely true. Probability theory comprehends the
fact that there are events for which the probability of occurence is
exactly zero as well as events for which the probability of occurence is
exactly 1. In the case of what you are citing above, one can, with
absolute certainty state that the probability of a container of helium
bursting into a chemical flame is exactly zero since helium is an inert gas
and will not combine with oxygen to combust. Another example of absolute
certainty: conservation of mass in chemical reactions. These are events
for which the probabilities don't approach zero or approach one, they can
be stated as being identically equal to zero or one.

I don't agree.

You could say "empirical evidence suggests it won't happen" or
"experience shows us it won't happen".

Stating a probability as exactly identical to zero is inherently incorrect.

Insert "of an empirical event" after the word "probability" in the
last sentence and I agree. Logically false (as opposed to empirically
false) statements do have a zero probability of being true.

"A and B and (A implies not B)" has a zero probability of being true.

But as someone said, we are picking fly specs out of pepper here. I
think LRod cited an interesting article pointing out the baselessness
of concerns about dust explosions from ducting. While he might have
slightly overstated the article's conclusions, those who are reacting
negatively to his absolutism (and I tend to be one who so reacts) are
missing or avoiding the message of the cited article.

You have a single die (a regular hexahedron, with the faces labeled "1", "2",
"3", "4", "5", and "6".

What is the probability of rolling a "7" ?

I do believe that saying "exactly identical to zero" _would_ be an accuracte
answer.

I'll willingly agree that the _question_ could be considered 'inherently
incoherrent'. *grin*

Probabilities are measured on a scale of 0 to 1.

Even a "zero" probability is not an indication that an event will never
happen.

A zero probability states that an even "almost never" happens. A
probability of one states that an event "almost always" happens.

Therefore, probability theory would state that, while the probability
of rolling a 7 is zero, there is still a chance (however small) of it
occuring.

Let me put this another way. Prior to 9/11/2001, most Americans would
have said that the probability of two airliners striking both towers of
the World Trade Center within minutes of each other and destroying
both, was zero.

Yet, it DID happen.

LRod actually did make a cogent point in one post that he was willing
to settle for a "reasonable estimate". That is actually a good way of
explaining the situation.

The lesson to be learned here is to refrain from making absolute
statements like "zero chance".

Alright, stepping into the realm of pedantry: From the axiomatic
definitions of probabilty theory (Papoullis, Probability, Random Variables,
and Stochastic Processes),
"The probability of an event a is a number P(a) assigned to this event.
This number obeys the following three postulates:
I. P(a) is positive: P(a) = 0
II The probability of the certain event equals 1: P(S) = 1
III. If a and b are mutually exclusive, then: P(a + b) = P(a) + P(b)"
[Version I have at home is McGraw-Hill 1965 version, page 7]

Note: from (I), P(a) = 0 is a valid probability. For the examples
stated, "a bucket of water bursting into flame", or "a unit of helium
bursting into flame", or "conservation of mass in a chemical reaction
holds" the probability of these events can be stated to be zero. Unless
you are going to imply that the laws of physics and chemistry are muteable
--- if that is the case, then the whole fundamental fabric of science and
technology is essentially destroyed. i.e., there is no, zero, zilch, zip,
nada chance that helium will burn (i.e. oxidize) in an chemical reaction --
helium is an inert gas, it cannot combine with oxygen, it *will not* burn.
This is more than "empirical evidence", it is a fundamental element of the
chemical nature and properties of elements. If we can say that there is
some non-zero probability that elements will behave willy-nilly contrary to
their fundamental chemical and nuclear properties, we are wasting our time
with science and technology. Thus, in these cases, one can indicate that
the probability of those events occuring P(a) = 0, and in addition, the
probablity of those events occuring are the impossible event. Further,
from II, it is also possible to have a certain event, for which the
probability = 1.

It is also important to note that one must distinguish between the
impossible event, and those events with probability = 0. For example, the
probability P(t = t1) = 0 may be true, but not necessarily an impossible
event. Same is true that even though the probability of an event = 1,
this is not necessarily the certain event. However, for the impossible
event P(a) = 0, and for the certain event P(a) = 1. But this is a side
detour to the original statement. The fact is that it is *not* inherently
incorrect to state that a probability is exactly identical to zero.

To add to the pedantry, if the quantum effect of neutron decay happened
all at once in the bucket (a negligible but not zero probability), the
helium could be changed into deuterium and/or berillium and/or lithium
and hence burst into flames. Hence, the probability is not zero.

Actually, I've never said anything about the actual numerical value, but
I would assert that it is 0 which would put my estimate closer...

My chief complaint is the assertion of no possible problem in any
system, sight unseen that is implicit in the proposition. The reference
he quotes, in fact, says specifically it can't be totally ruled out, but
is merely highly unlikely for home-shop systems, anyway.. If people say
that, I'll not complain a lick...if the claim the problem is totally

Why do you say this? Not everyone believe in the absolutely no absolutes BS
like some in here. There are things that are simply not going to happen ad
some like me believe more in statistical significance. If the chance is so
small that it becomes insignificant, this it simply has no chance. I can't
