Has anyone made a pseudorandom number generator based on how much adding a picture will screw up the formatting of a word document? There must be a way to quantify that and feed it into a program.
We had an electronic double dice device, but I didn't like the way my Dad licked his fingers before touching it. The noise of the real dice wasn't that bad but Dad preferred the 'random number generator' as he didn't like the board getting scratched by fingernails when picking the dice up! I don't know how random it was and if its probability of each number wsa 1/6 like with dice!
I'm reminded of a statistics class I took during first year university. We all had to buy a specific type of graphing calculator and were told to go through a particular exercise with a "random" number generated by the calculator. As this was the first time many of us used that function of the calculator, about half of us generated the exact same random number. I think our calculator diverged after that, but it was kind of amusing and a pretty clear illustration of how non-random computer-generated random numbers are.
It might've been because the graphing calculators needed a seed to be inputted from the user, and outputted the exact same numbers with the default seed. Or maybe not; that's just what might've happened. Yes, I typed this reply two years after this comment was posted.
I mean if anything, truly random numbers could end up in results like that anyway. Humans like to think of randomness as the things being different every time. But truly random numbers have a lot of repeats, and a lot of numbers that are never chosen at all. The calculator obviously isn't random because no computer can generate truly random numbers. But yeah the fact loads of people got the same number is, if anything, more random, not less.

I chose 1, because of its low chance of being guessed right. I thought 5, 6, 7, are the top contenders on picking a number from 1 to 10. The most fundamental part about *random* is all about semantics. Casually it most often means "something unexpected" or "a set of values with equal chances for one to be picked", and in many definitions "something without a definite plan". It is a very contextual word. I just love it how one word, random, can so well join psychology, mathematics, culture and linguistics.
One method I have heard of for generating random numbers in microprocessor boards is using the 3rd decimal digit of the ambient temperature as measured by an onboard thermal sensor... this won't repeat in cyclic patterns as you would get with using time...
What bitrate can you achieve that way? How long must you wait after reading the sensor once, for the next reading to have 0 correlation with it? Doing this a few times might be a tolerable way to generate the value of the *seed* of a PRNG, but for all practical purposes continue by using a computationally slick PRNG.
I chose 7 but immediately changed to 2 since I KNEW they were going to come up with some annoying psycho-mathematical BULLSHIT predicting my first choice, I hate it when that happens xD
Witch Hat Productions Hahaha, only unconscious reasoning matters? I'm not trying to look special or anything like that, I understand what the video is about, intuitively we tend to think that the most "random" number from 1 to 10 is 7, but thing is that there's people that rarely give an intuitive answer, some people will engage in conscious thinking when you ask them that, some people knows there's going to be a trick so they intuitively discard the first guess (me), some people will have previous knowledge of this trick and give you yet another answer, etc. I don't know why you are so adamant in saying that my answer is not "valid", we TEND to chose 7, we don't ALWAYS chose 7.
I usually pick 8 out of pure protest for the stats on 7, which of course makes it no longer random. Also, the numbers chosen around (and including) the 1 to make it a random part are the sequence for x/7. I can't help but notice that set of numbers.
Agreed. "Too complex to calculate" is not random. It should also be noted that you need outer limits for your random number. In this video they go 1-10, 1-6, 2-12 etc. If it was truly random and open, you could get very very large numbers, and they would be as probable as the lower ones. You also have to limit it to number sets. Do you want negative numbers? Imaginary numbers? Integers? etc.
Solid choice... I like 4. 4 is the only number where its english spelling uses the same number of letters as the number represents. ("four" has 4 letters).
4 is probably the second most common to be chosen. It's as close to the lower bound (1) as 7 is close to the upper bound (10.) So, they're close enough to being to the middle without being at the middle.
I think there is no randomness in the universe. Everything has a cause, even those individual electrons flying into detector not doing it randomly, but because of.. some processes that happens on that particular level. So basically there is no such thing as a random number (or anything, really...), even if we use events that take place in space to generate random nubers they wont be random but will represent 'breath of the universe'.
Another method used by many operating systems for generating random numbers for cryptography is to take seeds from all kinds of sources like hardware interupts down to the nanosecond and then run an encryption algorithm on it using previous number generated so rather than starting with one seed you have constant reseeding and after a couple minutes running the algorithm for the first time generally the random numbers while still being pseudo-random appear statistically random... Yarrow is one of those algorithms that is used by both /dev/random and the /dev/urandom on OS X (both are linked as OS X doesn't block like linux).
So where is the proof that the numbers that thing is providing are in fact random? How do we know that it's not just producing numbers in a pattern we're not currently aware of?
Current understanding of quantum mechanics is that it is described only by tuly random events and that no larger theory with currently unknown variables can explain our data. This was explicitly tested and ruled out in the Bell experiments, although I'm not an expert in the exact statement of the result.
The proof is that quantum effects are random since they are the consequence of a wavefunction collapse, and the wavefunction is nothing but the probability amplitude of a state.
A small upgrade to your program: choose apropriate time scale and iterate through binary length of a chosen number size (i.e. 8 bits). If in a given time scale electron reached a counter you set this bit to 1, else you set it to 0. This should make your program return value much faster.
For anyone who is familiar with this topic, the fact that he went straight for the strontium-90 to generate a truly random number should be no surprise. However, the explanation of how adding the result of N dice rolled tends to a gaussian distribution as N becomes large (aka the law of large numbers) was a digression, and I would have appreciated some discussion on why a radioactive element is necessary versus the "random" number generator embedded in your favorite program. Or even better, what alternatives exist besides radioactive ones.
People choose 7 because when we think of the word "random" we usually think of "what is the number with the least connotations with it". Which happens to be 7 when it's 1 - 10. When it's 1 - 20 people usually choose either 7, 17, or 19. When it's from 1 - 30 people usually choose 11, 17, or 19. When it's from 1 - 40, people usually choose 17, 19, 29, 31, or 37. Etc.
I definitely picked seven and for those exact reasons. I just have categories for all the other single digits, and so they don't feel random. Pretty cool
What if you want to generate a number between one and twelve? You get your d12 out. Then you grab your dice bag, tip 83 of them on the table and if any of them land on the floor you finish your drink and reroll them because those are the house rules. Honestly, what kind of nerd are you?
"Is there something innately random about the number 7?" Well, it's by far the hardest of the integers from one to ten to tell if another number is divisible by.
I hate to be overly philosophical, but can anything above the quantum level be truly random? Aren't the systems sufficiently deterministic as to always have patternicity, even if chaotic?
The radioactive source is truly random because of the quantum effects you mention. It's true physics is deterministic aside from quantum effects, but as with radiation, quantum effects can affect macroscopic things as well in some cases. In practice, for serious randomness (for example, for cryptography), computers will collect entropy from its environment, ie the exact arrival time of network packets or completion times of hard drive seeks. Like you say maybe these could be predicted in principle if you could know the exact state of the world, but this is practically impossible. Extreme needs (military?) may even put radioactive sources in the computer and use those timings.
Jeffrey Elliott No, nothing aside from quantum effects can be random. Every classical system is deterministic. The roll of a dice is deterministic. Us being too limited to do the complicated math to know what value will come out of the roll with arbitrary precision does not make it random, it makes it chaotic.
+Spiritman Productions Because every individual digit also stands for a number. 7 is both a digit and a number, whereas 17 would be a number consisting of two digits (1 and 7). Both would be correct really, but given we're talking about numerical concepts in our head, number is the adequate term.
The sum of dice does not approach a normal distribution. It is actually an Irwin-Hall distribution. They look similar, but Irwin-Hall has a much flatter top with shorter tails, and is a piecewise polynomial, not exponential.
I recently, this year started always picking 1 at these kinds of things, because shit has been getting real, high school graduation and the need of some serious choices has forced me into a new mindset for the future - I want to succeed, I want to be a winner so 1 is the only way to go.
6 and a half minutes in, ruffly, he made a communication mistake. He said you can't get a number between 1 and 12 with 2 dice because you cannot get the number one by adding the sums of 2 dice. Well 1 is not a number in between 1 and 12, 1 is the border, it isn't between the borders. Not a math mistake but it was an English mistake.
+Leather Rebel Justice When people say "between 1 and 10" the vast majority of people mean including 1 and 10. When people mean it to be exclusive, they state it explicitly. I'd argue he's using the common way of saying it rather than the mathematical way.
+DaffyDaffyDaffy33322 They could also mean 7000 and 189 but that isn't what they said. I mean your comment literally made me jump out of my skin. what do you think about that? Many people also use literally to mean metaphorically which would make the word literally useless if it meant both. I bet your own my side with that. So lets not give into common usage making English a less clear language.
The dice you speak of is a normal one. A dice in a casino for example doesnt have this issue, they are same on every side, including paint used for the numbers and dont have any holes, they even have a sharper edge, which makes the product much more "random" than the usual dice.
I choose random numbers between one and ten by looking around the room and choosing the number of letters in the first word I see. If I don’t see any words, then just the first word that comes to mind. I realize that this isn’t a uniform distribution, but I am happy with my normal distribution.

i pretty pissed that i picked 7 >,
i choose 9;-;
I definitely picked seven and for those exact reasons. I just have categories for all the other single digits, and so they don't feel random. Pretty cool
For a random number why not just use pi?
I chose Pi
i chose tau!

Gman5938 that is bigger than 6, and therefore basically 7
+Knuf Wons
Someone doesn't know the .5 rule :D
Knuf Wons
yeah but 2 is lower than 5 so its still 6
I pick 9.95136833564228, exactly that number, deal with it
This guy is sick!! the first youtube video I liked and commented on
I chose 3 ...
What if you want to generate a number between one and twelve? You get your d12 out. Then you grab your dice bag, tip 83 of them on the table and if any of them land on the floor you finish your drink and reroll them because those are the house rules. Honestly, what kind of nerd are you?
I mean honestly!
Quiet decently honest explanation of randomness and random numbers🍥
"Is there something innately random about the number 7?" Well, it's by far the hardest of the integers from one to ten to tell if another number is divisible by.
I hate to be overly philosophical, but can anything above the quantum level be truly random? Aren't the systems sufficiently deterministic as to always have patternicity, even if chaotic?
The radioactive source is truly random because of the quantum effects you mention. It's true physics is deterministic aside from quantum effects, but as with radiation, quantum effects can affect macroscopic things as well in some cases. In practice, for serious randomness (for example, for cryptography), computers will collect entropy from its environment, ie the exact arrival time of network packets or completion times of hard drive seeks. Like you say maybe these could be predicted in principle if you could know the exact state of the world, but this is practically impossible. Extreme needs (military?) may even put radioactive sources in the computer and use those timings.
Jeffrey Elliott No, nothing aside from quantum effects can be random. Every classical system is deterministic. The roll of a dice is deterministic. Us being too limited to do the complicated math to know what value will come out of the roll with arbitrary precision does not make it random, it makes it chaotic.
For anyone wondering, the pseudo-random number generator he described is called a Linear congruential generator.
Its funny because i picked 5 for my random number
I picked 9
Me too
Baby Lady Bug don't tell me what to do
Me too
+Kien D. N. Same here.
Snap
Me: picks 4
Them: *throws 4 out because it's even*
I chose four!
Welcome to the club of those who chose 4
Great video and all, but, when referring to individual digits, why do you still say 'number' and not 'digit'?
+Spiritman Productions Because every individual digit also stands for a number. 7 is both a digit and a number, whereas 17 would be a number consisting of two digits (1 and 7). Both would be correct really, but given we're talking about numerical concepts in our head, number is the adequate term.
He was talking about integers in the range 1..10 (and, later, 1..6, so that he could use a d6). So why not say "number"?
Random usually means unpredictable.
I chose 12, how likely was that?
Very unlikely (the number was to be between 1 and 10).

@@GregorShapiro wooosh
I chose 10, then 6. I'm different.
I think that the video ending with a 0 is a pretty good demonstration of random numbers.
I chose 7, but only because I like that number
+Xoran LP Then it's not a random number :)
I'm unable to choose a random Number. Realy
Seven Costanza
i thought before he said "between 1-10" i was thinking about 14 so i thought OK HALF OF THAT and thats how i got 7
Great great video!
The conclusion thereby is that the most random number is not 7 or 3, is 10.
and this my friends is why i have i have a 1000 sided dice the size of a basket ball
How do you even tell which side is up one you roll it?
Actually the largest dice in which all sides have an equal probability has only 120 sides
I chose +-3.
But u got 7 likes
The sum of dice does not approach a normal distribution. It is actually an Irwin-Hall distribution. They look similar, but Irwin-Hall has a much flatter top with shorter tails, and is a piecewise polynomial, not exponential.
I've chosed 7 :))
Hey I chose 6
So, I checked frame by frame and the 3 6’s that were rolled were in the SAME ORIENTATION!
8:22 He must play ShadowRun a lot
I asked my mom and dad separately, both said 7 LOL
you have 7 likes
Whenever you need a random number, just use 7.
So that is how we win at lotto? cool.
I picked 4. Feeling pretty good about that.
I recently, this year started always picking 1 at these kinds of things, because shit has been getting real, high school graduation and the need of some serious choices has forced me into a new mindset for the future - I want to succeed, I want to be a winner so 1 is the only way to go.
i guessed 6 because its random :P
6 and a half minutes in, ruffly, he made a communication mistake. He said you can't get a number between 1 and 12 with 2 dice because you cannot get the number one by adding the sums of 2 dice. Well 1 is not a number in between 1 and 12, 1 is the border, it isn't between the borders. Not a math mistake but it was an English mistake.
+Leather Rebel Justice That's a bit ruff.
+Leather Rebel Justice When people say "between 1 and 10" the vast majority of people mean including 1 and 10. When people mean it to be exclusive, they state it explicitly. I'd argue he's using the common way of saying it rather than the mathematical way.
+DaffyDaffyDaffy33322 They could also mean 7000 and 189 but that isn't what they said. I mean your comment literally made me jump out of my skin. what do you think about that? Many people also use literally to mean metaphorically which would make the word literally useless if it meant both. I bet your own my side with that. So lets not give into common usage making English a less clear language.
+Leather Rebel Justice I was thinking the same thing. He meant "from 1 to 12" but said "between 1 and 12". It's a very common mistake, though.
+Leather Rebel Justice no
The dice you speak of is a normal one. A dice in a casino for example doesnt have this issue, they are same on every side, including paint used for the numbers and dont have any holes, they even have a sharper edge, which makes the product much more "random" than the usual dice.
I choose 7
Dammit
“That’s the happy sound of radiation”
I choose random numbers between one and ten by looking around the room and choosing the number of letters in the first word I see. If I don’t see any words, then just the first word that comes to mind. I realize that this isn’t a uniform distribution, but I am happy with my normal distribution.
i chose 9
I said pi.
all I've learned is that there is no such thing as true random. This is incredibly valuable information
I just blurt out whatever number I happen to be thinking of at the moment
Once my “number” was waffle...
...I then corrected myself and said “wait no, pancake”...
...it legit took me a few seconds to realize breakfast is not a number
Also I pick one
cool cool
