Very interesting discussion. I also heard that the radioactive decay of Cesium was a good source of entropy, but now that I know it's used in atomic clocks, it kind of debunks that theory....too regular, just like the electronic interference of high power lines in atmospheric noise-generated random numbers.I still say there is order to chaos and we just have to decipher the order. Ion Saliu suggests studying what numbers come in with other numbers and I think it's a valid starting point for pr... [ More ]

Yes medical magnetic resonance scans work because of this particular property of matter.Light amplification in lasers also work because of a similar effect, I think that the atom's outer electronic orbit absorbs energy and then unable to hold it for long, discharges it and the cycle is repeated again and again.

If numbers were truly random, Would that not be a pattern in itself

funny stuff, on one hand Cesium 137 is considered a good source of entropy while Cesium 137 runs atomic clocks because of it's resonant stability...atoms (and molecules) have resonances; each chemical element and compound absorbs and emits electromagnetic radiation at its own characteristic frequencies. These resonances are inherently stable over time and space.read more about atomic clocks here... http://www.howstuffworks.com/question40.htmand an interesting article about the beta decay of Cesi...

Wow! Just looking at the votes it becomes real obvious as to why we all have such differing views on why or why not we can attempt to predict the lottery. We can't even agree on a true source of random numbers. One must consider if a true source of randomness really exists or not.

Theres no true randomness.All are false randomness.

This is a hot topic with cryptographers and math lovers. It is a question (what is truly random?) that may never be answered. The best source (and agreed upon by most, if not all) has to do with the radio active decay of something (I forget what). If you are interested, and would like to download some random numbers, use this URL:http://www.fourmilab.ch/hotbits/I wrote a program for encryption a few years ago that uses these random numbers. There are a number of tests that can be done to dete... [ More ]

But, I almost forgot, getting back to the topic and the question, there probably isn't anything as random as the (Not the human brain) human mind.

RickYou do have the right idea.Reality is sort of a two way street so to speak.It makes you and you make it.It is two way and self sustaining. Before anything comes to be (Becomes) it first has to be seen by the mind (Mind's eye} Edgar Cayce used to say. The mind is the maker He also used to say.Reality is (Something) of the mind (Only).Without it (The mind} there is nothing.Because, after all, reality (The universe=Creation} was created by The Mind (God}.I guess that Random turned into M...

Excalibur,That's the beauty of RNG's based on atmospheric noise. What could be more timely and random than today's atmospheric noise? I'm a big believer that universal consciousness affects everything that happens. Example: exactly one year after the 9/11 attack, 911 came in NY Evening draw. The number was definitely on a lot of people's minds that day. Unless they rigged the drawing, I'd say it was a good indication of us having a say-so in randomness.Just a thought, but I like the con... [ More ]

My question would be. Is anything in creation random?Was the universe designed to be random?My answer would be, pre-creation was random or chaos, same thing.The only thing that I can think of as being anything close to random at all in the universe is a non charged sub-atomic particle colliding or hitting another non charged subatomic particle.But as to how anybody can make use of this to produce random numbers is beyond me.

My vote is atmospheric radio noise. For a good random number generator using this method go to random.org
