can someone tell me what's the physical system of Henon and Ikeda attractor?? or tell me some web side about this, because i need to do an assignment:wink: thank you!

Wolrams story reminded me of one from the National UFO reporting center: http://www.nwlink.com/~ufocntr/ First, this is nothing like Wolram's story in that Wolram's is interesting; this one is kind of funny and sad. I'm not sure when this took place; I read this a few years ago somewhere...

Hi all, maybe this is not the proper forum to post this. Because it rather belongs into a section 'strange effects in everyday life', or whatever. Well. Yesterday I opened a bag of peanuts. The ones that have the closed shells which contain two nuts each. I found the best way to crack them...

Strange Sun-like Object... Any Ideas? A few days ago, my family and I were stuck in a traffic jam on the expressway about an hour before sunset. There were no clouds in the sky and my sister pointed out what appeared to be a small sun a quite a bit to the southeast of the larger one. I have...

What do people make of the following quote, attributed to Kissinger? It reminds me of Ronald Reagan's comments regarding an extraterrestrial threat to Earth(which he made at the UN, around about the same time as this). "Today, America would be outraged if U.N. troops entered Los Angeles to...

According to SR, a photon has an equivalent mass of h / c λ where h is plank's constant, c is the speed of light, and lambda is the photon's wavelength. So, at some point the equivalent mass of the photon should be sufficient to cause a black hole. (Using the simplified formula I...

i was playing with numbers the other day and noticed this - Anything multiplied by 9, will equal 9 when added this is really weird considering that it doesent work with any # i know this belongs in the math forums, but using physics could generate a good theory, it may be stupid but...

f(x) = (1 - x^2)^1/2 This all stems from me approximating pi by numerically evaluating the integral S f(x)dx from 0 to 1 and multiply the sum by 4. Now... Would you agree that f(x) has a derivative f'(x) = (1 - x^2)^-1/2 * -2x ? According to my textbook this is so. Now I can...

Not quite sure where this post should go so I'm putting it here. My wife and I were walking the dog the other night and looking toward scorpio we saw a flash of light and then a very broad "vapor trail" like a glowing stripe crossed upwards across the sky. We walked on further and about five...

So I came across a question in a quiz book the other day and I still haven't been able to answer it, so I figured I would ask some experts... Here goes... As a NASA senior physicist, would you agree with the calculation made by a junior physicist regarding the speed of an artificial...

1/7 = 0.142857142857[/color]... 2/7 = 0.2857[/color]14285714[/color]... 3/7 = 0.42857[/color]1428571[/color]... 4/7 = 0.57[/color]1428571428[/color]... 5/7 = 0.7[/color]14285714285[/color]... 6/7 = 0.857[/color]142857142[/color]... That's strange.

For you statisticians out there, I have long wondered about the possibility of evaluating the "truth" of personal claims by using statistical analysis. Considering the incredible success of demographics and other fields, might this also be possible. If you look at my other threads you will...

makes sense eh?
