How long until everyone in the world is a member of my group?
based on totady world population or do we have to factor in the population growth rate?

In other words, you have no proof that the 35 million doesn't contain any engineers as your sloppily worded post originally implied.
Got it, thanks.
Better than you, twoof.
AE911T's growth over 5 years at 20% per year compounded annually (I'm being really generous here):
1000 x .20 = 200
1200 x .20 = 240
1440 x .20 = 288
1728 x .20 = 345.6
2073.6 x .20 = 414.72
ASCE's growth over 5 years at half of what I gave AE911T, also compounded annually:
147,000 x .1 = 14,700
161,700 x .1 = 16,170
177,870 x .1 = 17,787
195,657 x .1 = 19,565.7
215,222.7 x .1 = 21,522.27
And now here's AE911Ts growth subtracted from ASCE's:
14,700 - 200 = 14,500
16,170 - 240 = 15,930
17,787 - 288 = 17,507
19,565.7 - 345.6 = 19,220.1
21,522.27 - 414.72 = 21,107.55
Each year, ASCE's growth and AE911Ts gets bigger and bigger.
So yeah... AE911T will never grow as big as ASCE. Sorry to be the bearer of bad news. Especially since you don't seem to be able to figure these things out yourself.
Not only do I have "no proof" that absolutely no engineers were in the random samples employed in those polls, I expect that there would have been engineers in those samples, if the total sample size was in the hundreds, since the probability of engineers in the sample is in the neighborhood of 1.5 million / 300 million, or .5%. Like I said, you're nit-picking. That's all you got, because your comment was so dumb.
You still don't get it, do you? (Nice switcheroo from all engineers to ASCE, btw. Say, why'd you do that?) If you had any substantial mathematical acumen, I'd tell you that your problem may be that you don't understand that you're not comparing linear functions. Since you seem awfully naive, mathematically, I'll just tell you that you're out of your element.
Here's your last chance to get it. I don't expect you to admit your error, but at least you can give it up and stop embarassing yourself.
You can see how wrong you are by picking a larger number of years.
I'll pick 40 years.
147,000 * (1.1)^40 = 6,653,110
1,000 * (1.2)^40 = 1,469,771
Not quite, but notice that the difference in membership numbers is now in the miilions, advantage ASCE. specifically, 5,183,339.
So, take 55 years.
147,000 * (1.1)^55 = 27,791,693
1,000 * (1.2)^55 = 22,644,802
Nope, bad guess. Note, though, that the difference has now decreased to 5,146,891. This should tell you immediately that there's something wrong in how you're thinking about this.
I'll take 100 years.
147,000 * (1.1)^100 = 2,025,750,013
1,000 * (1.2)^100 = 82,817,974,522
Seriously, let the spouse make the investment decisions for your household. And before you embarrass yourself further, do yourself a favor and PM a fellow debunker who understands how compound interest works, OK?
I'll take 100 years.
I can see you're not very good at math. Perhaps W.D.Clinger will be good enough to explain to you why you're wrong. Or, you can go ask any banker or accountant "If I deposit $1,000 at 16% interest in one account, and $1,000,000 at 1% interest in another, will the first account ever exceed the second?" If you really want to have fun, you can solve for y (=years) where
((1,000)^1.16)^y = ((1,000,000)^1.01)^y
It might be a good idea to let your spouse handle the family finances...![]()
This should be
(1,000) * (1.16)^y = (1,000,000) * (1.01)^y
Five years isn't long enough, because AE911T isn't growing all that fast.AE911T's growth over 5 years at 20% per year compounded annually (I'm being really generous here):
You're almost certainly right that AE911T will never become as big as ASCE, but metamars wants us to consider the hypothetical situation in which the current growth rates continue exponentially into the indefinite future, disregarding all of the reasons that won't happen.So yeah... AE911T will never grow as big as ASCE. Sorry to be the bearer of bad news. Especially since you don't seem to be able to figure these things out yourself.
Why'd you change the numbers?You can see how wrong you are by picking a larger number of years.

For those of us not up on obscure TV trivia who was the doctor on the Brady Bunch whose name appears as a PhD on the AE911T site? Are you sure it's not some one with the same name?
Today, I have one member in my group. Next year, I convince some one else to join me. The following year, I convince two more.
Each year, my group has grown by 100%.
Now I stop taking data. And instead make wild, extravagant assumptions about how sustainable will be this growth rate.
How long until everyone in the world is a member of my group?
What are the odds that this is a group of people competent in math or statistics?
So, you are a member of A&E911T? What architectural or engineering qualifications do you have?
You know the ae911truth is very clear that anyone can join.
Interestingly a great analogy to the growth issue is assuming it's based on a 'fixed interest rate.' Except I'd point out that since the variables dictating who signs up, aren't set constants, the assumption is rendered moot..
Exactly. The assumption of constant annual percent growth is absurd.
One main reason is the example I gave. It is easy to generate large percentage changes in small numbers. It's much harder to do so in large numbers.
A bigger effect is that we have already passed "Peak Nutty Engineer", and are on the downslide. This was made obvious when he presented to (IIRC) 20,000 architects & engineers at the San Fran show this year...
... and managed to sign up TWO newsuckers"less than first rate, competent architects".
Here, BTW, is the standing of AE911t, Pilots4twoof & Randi.org in internet traffic for the last 6 months.

The Truth Movement is about to extinguish.
Tom
how is growing by .8% in 3 months a bad thing?
just askin'.
Yes with numbers like this it will be hard for the marines to keep you guys down.You know the ae911truth is very clear that anyone can join.
Just because we don't have any support from licensed structural engineers doesn't mean that we are not a power for change.
We are only a thousand from around the world and we have at least 80 licensed structural/civil engineers. But we are growing and we have a leadership that is dedicated to change. We have the stamina to keep going and it seems to me the debunker movement is tired and finished. They have said everything they can say, while we can keep going.
How about an alternate hypothesis to explain Telltale Tom?Telltale Tom, instead of quibbling over irrelevant details that won't ever change a single thing in the real world, would you care to take a stab at an alternate hypothesis to explain 9/11?
