You can't even write the number of digits contained in Graham's number, or the number of digits contained in that number, and on and on more than a googol times.
Considering the suffix -illion, the googol can also be called 10 duotrigintillion! (The prefix's number is 32; the prefix is duotriginti-) The -illion function is Y = 10^(3X + 3), where X = the prefix's number & Y = the actual number. Doing the algebra, 10^(3 * 32 + 3) = 10^(96 + 3) = 10^99 (or 1 duotrigintillion); multiply that by 10 & you get 10^100, which is commonly called the googol!
it's almost 4 am, phone battery is at 1%, I'm hungry, need to take a leak, and I think I might need some sleep especially since I'll need to get up at 9.
Any number that is defined by a finite number of digits is by definition smaller than infinite. And a googolplex to the googolplex'th power is big, but still finite. Even if you won't ever have enough ink in the universe, or particles in the universe, to write it down.
This reminds me of something mentioned in Star Trek called Hodgkin's Law of Parallel Planetary Development. It's basically a version of convergent evolution that applies to entire planetary ecosystems in comparison with other planetary ecosystems, and to some extent to societal development as well. It also brings to mind the idea that duplicates of planets and people would arise in an infinite universe, basically for the reason given in this video: that there are only so many ways you can arrange particles before you have to start using the same configurations again.
This always annoys me, the whole "if you travel far enough in such a big universe, you would eventually encounter exact copies of yourself". Because that implies that every configuration is equally likely to occur, which surely it isnt. For it to be certain, the universe would have to be infinite. And even then, certain configurations would occur more frequently than others. Just like, yes there are an infinite number of prime numbers, but they still dont occur as often as for example even numbers; encountering an even number is much more likely than encountering a prime number.
Yep, I had the same problem. He assumed equal probabilities of configurations within a volume. Therefore I believe that even in a googolplex sized universe, I'd still be the only me. The analogy he presents is still useful for understanding the size of the googolplex number, however.
I think you are correct and the reason is the second law of thermodynamics - the more enthropy states must occure more often then the less ethropy states. Hence, humans are rather less enthropy state so we are very rare state of atoms.
crcaccounts You guys are being silly. Pretending that the universe is a googolplex meters across is arbitrary. If we instead pretend that the universe is a googolplex^googolplex meters long, you'd end up with an incomprehensibly large number of copies of yourself, even taking into account the uneven probability of various configurations. It's just a thought experiment meant to make understanding this stuff easier.
SidV101 Two things: you say that universe is infinite by size while discussing the combinations of matter which is also energy. Shortly I am in a sort some state of energy ( and a wave if we add quantum theory). Continuing universe is infinite in a way that in 3 dimensions you would never reach the edge of the universe but it can contain inside finite amount of energy (all the rest is just vacuum). So to state that there is infinite amount of my copies you would need to prove that infinite by size universe contains infinite amount of energy/matter in it. Like 2d world can be infinite but finite in 3D ( like surface of balloon) and s contain finite amount of some other attribute. Second what was pointed out in vid they state that there is finite amount of combinations of matter and then they limit the size of universe by some very large number. Then simply divide assumed size of universe by number of combinations to result the expected amount of our replicas in the universe. We pointed out that for this result to be correct they also assumed that probability density function of matter combinations is uniform what may be wrong by- more natural in the world is the Gauss distribution and second thermodynamic law states that simply contradicts to uniform distribution of energy\matter. So in my opinion their calculation is wrong as they made a hidden assumption that that I thing is wrong. If you can proove that more naitral for matter distribution in the universe is the uniform distibution than I must be wrong otherwise please buy a book of level 1 statistics and learn something useful.
You won't actually meet them let's suppose, 1. 1. 1 So you traveling from left to right, soo your other repetitive form will also travel from left to right, your three form going in same way, so no chance you gonna meet them, what's I'd thats life wtf 💀
@@Bluelightzero Right. It's probability, not a fact really. However, you can definitely say that there would be exact copies of /something/ in a universe that is large enough. Using you example of a line of coins, with truly random probability you can't guarantee that you will ever see 2 Heads. Though unlikely, it's possible to never even get one Head. However, since there are only 2 states, you can guarantee getting either 2 Heads or 2 Tails within 3 tosses. In the same way, in a universe large enough, some of the states must repeat as soon as the sample size is more than the number of possible states. However, it might not be a person that repeats. The universe could just have repeated spaces that are just a Meter^3 sized vacuum.
@@Bluelightzero It's not an incorrect calculation, though, mainly because they didn't really calculate anything like that. It's an estimate. In fact, it is a very strong estimate. For the numbers they use, 10^10^70 is the number of possible states and 10^10^100 is the sample size. I'm going to call these PS and SS for "Possible States" and "Sample Size." They didn't really emphasize this, but SS is unimaginably larger than PS. How much larger? Let's look at orders of magnitude (OoM). The OoM for PS is 10^70 and OoM for SS is 10^100. The difference in the OoM's is simply 10^100 - 10^70. Is it 10^30? No.... not even close. Let's look at the OoM of those OoM's. OoM(OoM(10^10^100)) = OoM(10^100) = 100 OoM(OoM(10^10^70)) = OoM(10^70) = 70 10^100 is 30 orders larger than 10^70, which means 10^70 is negligible in comparison. This means that 10^100 - 10^70 = ~10^100. No joke. The actual value would be between 10^100 and 10^99, but it's wayyyyy closer to 10^100. By extension, since 10^70 is essentially 0 in comparison to 10^100, 10^10^70 is roughly 1 in comparison to 10^10^100. Just by this, you can tell it is extremely unlikely to not have duplicates in a universe that large.
@@joshandrews8913 yes but the point of him bringing that up was simply to enthasize how big a googleplex is. And due to us not knowing our quantum states exactly, we still have a rough estimate, and a google plex is so big that even if our estimate was too low, the chances of seeing duplicates is still high
@@benhayter-dalgliesh5794 We're talking about exact copies, too. We wouldn't be able to tell if two things are exactly the same as long as they are close enough. If we include states that are similar enough that we couldn't tell the difference, the probability would be even greater. I don't think you're disagreeing with me, though. Emphasizing the size of a googolplex is the point.

Cubes do have radius. It doesn't mean the same as a sphere tho. The radius of a cube is a line from the center of the cube to a surface perpendicularly. Also known as 1/2 the side of the cube.

jlrockafella I'm was kidding, even though if you look far enough, there would at some point be another universe that is exactly as ours, not just in shape, but also in history.
Hey numberphile, you could write a googolplex in the observeble universe. If you wrote on every plank length (the smallest distance), you could get to about 10^10^183 to 10^10^184.
Finding repetitions would assume that each volume of space you encounter is a random arrangement of atoms, when nearly all of the volumes would be a vacuum. But perhaps a googolplex is big enough that on the rare occasion you are able to find seemingly random atomic arrangements (like the surface of a planet with life) you might find repetitions still.
Googol = 10^100 which is 1 followed by 100 zeros Googolplex = 10^10^100 which is 1 followed by a Googol zeros Googolplexian = 10^10^10^100 which is 1 followed by a Googolplex zeros
Could you please explain why you would see repetitions? I mean, if you travel that far away why there wouldn't be just repetitions of vacuum or stuff like that? How many chances there is to see the exact same repetition of our solar system and galaxy and whatever?
+Rohan Mishra It's not that big relatively speaking. Most people would over-estimate, I know I would. I would probably guess somewhere in the septillions.
What is even more fascinating to think about is within that 10^10^70 different possibilities of matter arrangements within a cubic metre, how many would there be of something that's almost you but just a couple atoms different, or even thousands different...which for all practical and noticeable purposes would be an identical copy of you. If you think about how small 1,000 atoms are, the difference between you and a version of you with 1,000 atoms that are different would essentially be an exact copy. HOWEVER, to play a little bit of Numberphiles own probability game here, just because after 10^10^70 possibilities the process must repeat, does not mean the 10^10^70 + 1st version is going to be you again...or for that matter that you will necessarily get two of you in (10^10^70) x 2 metres of space, or a million of you in (10^10^70) x 1,000,000 cubic metres of space. It's just the PROBABILITY. It's like flipping a coin...you probably won't flip all heads or all tails in 100 flips but it's not impossible. In a universe of that size the probability is that there is a million of you, but there could be just one, or 12, or 50 billion. For whatever reason your pattern could repeat alot, or not at all, and only other patterns have repeated. 🤯
It's impossible to run into an exact copy of yourself, because they are unknowingly moving further away from you at the same rate you're moving closer to them. From your perspective you'd simply be back where you started, even though your surroundings are (unnoticeably) different
It’s funny because they’re like : “That guy invented the googol and the googolplex” and I’m like : “Well, I invented the coocol (10^1000) and the coocolplex (10^10^1000). I’m a genius.”
i think that's a really cool idea, but i dont really like how he keeps saying "if you go far enough". the point is that there could be an exact replica of me on earth right now, its mathematically POSSIBLE however unlikely. he is pointing out that if the universe were that big, my double would pretty much be a mathematical certainty. it's a really cool idea, but its not like there is a specific distance you would have to travel to find your double. i guess technically traveling would increase the number of arrangements matching your approximate mass thus increasing the chances of you FINDING your double.... but traveling in one direction i don't think would guarantee you would find that particular arrangement in such a vast universe
In response to Jakka Makka: "how is a particle larger than a grain of sand?" It is not, he was counting the total number of particles in the universe, not the number of particle you could fit. There is space between particles.
So we're looking for 2^x = 10^googol, and by taking the log2 of both, we get x = googol * log2 (10), or approximately 3.32 googol (that's 3.32 * 10^100) 3.32 * 10^100 planck times * 5.85 * 10^-50 years per planck time = 19.4 * 10^50 years (more properly rewritten as 1.94 * 10^51) That's 194 trillion trillion trillion trillion years, or 14,160 trillion trillion times the current age of the universe.
The problem I see with taking the possible number of quantum states of a give volume being less than a googolplex to indicate potential duplication of an individual is that it assumes the configuration to be entirely random, and doesn't account for the probability of the necessary chemical reactions to produce that state. Still, it's a fun analogy :P
Well base knowledge wise he meant as Googole and googoleplex have an ending no matter how big it is but infinity it just keep going numbers Increase more and more so infinity is big so big it practically never ends numberwise. It all just based on how we categorised the numbers in a bunch
This got me thinking about intuitionistic mathematics and their problems with infinity... If we established a number that could represent all possible states of the universe, would this settle down a conflict between classic and intuitionistic math? By the way, could you guys make a video on intuitionism vs. formalism vs. logicism? I believe it to be a really interesting topic. Thank you for this channel!
Somebody messed up. If 10^80 = number of particles in universe then 10^90 couldn't possibly be the number of sand grains to fill it. There is no way in hell that's accurate, like, at all, not even remotely close.
Its because most of the universe is actually empty space so if u fill the universe with grains of sand (that obviously contain particles) then it would be larger and have more mass and a higher density
except that particle aren't arranged by chance, I suspect you would run into many more empty cubic meters or meters filled with other elements before you ran into a copy of anything more complex just by chance
The number for these repetitions must be significantly smaller, since that was based on possible quantum states. For example, in a large enough universe, a person could be naturally formed by evolution much more commonly. And if there was a copy of you that had a small scratch in an arm, that wouldn't be accounted for in the calculation either.
This seems to imply that every possible arrangement of particles only occurs once in the Universe, not taking into account the relative probability of different states. :| Obviously, most f it is void or simple gases (Dark M&E aside), while more complex structures like living beings are less frequent. It could conceivably be a googolplex of nothingness.
Johann Diaz We know our observable universe is to small to have guarantied copies of ourselves, but what if the universe was much bigger than we thought? In that case, ima go invent wormholes, gather all of my copies, take over the universe, and put infinite likes on this video.
***** your comment has a major contradiction. Worth is what humans believe is worth. What you meant to say, or should have said is that money has no inherent value. But nothing does, even food is valueless if their are no humans. The only difference between money and food is that we chose to assign value to money, while we needed to assign value to food. But that doesn't mean money is worthless. Money is most certainly not worthless. So long as we continue to assign it value.
The notion of "this is how many possible quantum states the stuff that you are made out of could be in, therefore it's a 1/(that number) chance of it being you" isn't quite sitting right with me. It sort of implies that certain quantum states aren't preferred. And I don't know if this is true.
This conclusion seems wrong. Just because there are 10^10^70 different states available doesn't mean that every meter is some random combination of atoms. There are huge pieces of space where the state is almost identical for long stretches.
That's what I was thinking too :) but I believe he presented it that way so that we can imagine how impressive the number is, but most of the universe is empty space ^^ (sorry if english mistakes)
I think the assumption is that you'd have an observable universe with particles in it to match the scaled up size. Otherwise you'd reach the end of our universe, the extent of the expansion of space from the original singularity and simply have emptiness.
Which makes it even more likely. We know that the universe isn't some random number generator, and typically things happen for reasons, albeit chaotic reasons. This means that, because the universe is rule-bound, it would be far more likely than the chance mentioned in this video that you'd find a copy of yourself somewhere in a universe that large.
Think of it as a dice with 10^10^70 sides. If you rolled it 10^10^100 times, you would expect to see at least one roll of the same number. Of course, it's not even possible for you to not get the same number twice. You would get 10^10^30 (I think) duplicates. FOllow me?
even if I were to be in a universe where everything was repeated once, I could still make an army of myself. with memories being stored physically, and with how little it takes to change things, I could have the front lines all be virgins, but some of them had pizza for lunch last week while others had fish and chips, and a third group that skipped lunch. I could have the me's that don't need glasses flying the jets, while the me's that actually went through with working out while watching youtube could be the on the ground. the generals could be the me's that have a lot of experience coordinating large groups of people, while the nurses would be the me's that tried a little better in school. they are talking about EXACT copies, but if you have tolerance of tiny changes (got a scar from slipping with a knife, different haircut, shaved vs unshaved) you can get a huge number of copies
Counting to a trillion (1,000,000,000,000) can take less than 3 mins! If everyone on earth could count to 135 at the same time. (world population: 7.3 billion, it's like counting to 7.3 billion per sec) Imagine all living things on earth (including: humans, animals, and other species) all together about trillions (just guessing not sure thou) if all trillion of us counted to 1 million at the same time we can reach 10^18 in less than a 2 weeks. But googol is just so freaking massive 10^18 is only 0.000000000000000000000..1% of a Googol (10^100)
Scientifically it's a billion. 1,000 = thousand 1,000,000 = million 1,000,000,000 = milliard 1,000,000,000,000 = billion 1,000,000,000,000,000 = billiard 1,000,000,000,000,000,000 = trillion That's long scale and look Tony Padilla from Nottingham University uses it even though he's British, where short scale is predominant. It's important to know both scales if you travel even around the Europe. But in science they use long scale. Same as SI. Which sometimes causes problems in international conventions when USUALLY mathematicians, and physicist with so so knowledge of English will read something in short scale and have to apologize and say it in a long scale, same for scientist from British and American societies, sometimes they slip up (Americans tend to do it more often, it's more imbedded in their Uni life.

@@Bluelightzero It's not an incorrect calculation, though, mainly because they didn't really calculate anything like that. It's an estimate. In fact, it is a very strong estimate. For the numbers they use, 10^10^70 is the number of possible states and 10^10^100 is the sample size.
I'm going to call these PS and SS for "Possible States" and "Sample Size." They didn't really emphasize this, but SS is unimaginably larger than PS. How much larger?
Let's look at orders of magnitude (OoM). The OoM for PS is 10^70 and OoM for SS is 10^100. The difference in the OoM's is simply 10^100 - 10^70. Is it 10^30? No.... not even close. Let's look at the OoM of those OoM's.
OoM(OoM(10^10^100)) = OoM(10^100) = 100
OoM(OoM(10^10^70)) = OoM(10^70) = 70
10^100 is 30 orders larger than 10^70, which means 10^70 is negligible in comparison.
This means that 10^100 - 10^70 = ~10^100. No joke. The actual value would be between 10^100 and 10^99, but it's wayyyyy closer to 10^100.
By extension, since 10^70 is essentially 0 in comparison to 10^100, 10^10^70 is roughly 1 in comparison to 10^10^100.
Just by this, you can tell it is extremely unlikely to not have duplicates in a universe that large.
@@joshandrews8913 yes but the point of him bringing that up was simply to enthasize how big a googleplex is. And due to us not knowing our quantum states exactly, we still have a rough estimate, and a google plex is so big that even if our estimate was too low, the chances of seeing duplicates is still high
@@benhayter-dalgliesh5794 We're talking about exact copies, too. We wouldn't be able to tell if two things are exactly the same as long as they are close enough. If we include states that are similar enough that we couldn't tell the difference, the probability would be even greater. I don't think you're disagreeing with me, though. Emphasizing the size of a googolplex is the point.

A particle is much smaller than a grain of sand. What he means is that there are less particles than you could fit grains of sand into the entire universe because much of the universe is empty space. There are no particles there but you could put sand there

The radius of a cube is a line from the center of the cube to a surface perpendicularly.

Hey numberphile, you could write a googolplex in the observeble universe. If you wrote on every plank length (the smallest distance), you could get to about 10^10^183 to 10^10^184.
actually the number of planck volumes you could fit into the universe is about 10^185, which is less than Googolplex by a long shot.

Finding repetitions would assume that each volume of space you encounter is a random arrangement of atoms, when nearly all of the volumes would be a vacuum. But perhaps a googolplex is big enough that on the rare occasion you are able to find seemingly random atomic arrangements (like the surface of a planet with life) you might find repetitions still.
Googol = 10^100 which is 1 followed by 100 zeros

What is even more fascinating to think about is within that 10^10^70 different possibilities of matter arrangements within a cubic metre, how many would there be of something that's almost you but just a couple atoms different, or even thousands different...which for all practical and noticeable purposes would be an identical copy of you. If you think about how small 1,000 atoms are, the difference between you and a version of you with 1,000 atoms that are different would essentially be an exact copy.
HOWEVER, to play a little bit of Numberphiles own probability game here, just because after 10^10^70 possibilities the process must repeat, does not mean the 10^10^70 + 1st version is going to be you again...or for that matter that you will necessarily get two of you in (10^10^70) x 2 metres of space, or a million of you in (10^10^70) x 1,000,000 cubic metres of space. It's just the PROBABILITY. It's like flipping a coin...you probably won't flip all heads or all tails in 100 flips but it's not impossible. In a universe of that size the probability is that there is a million of you, but there could be just one, or 12, or 50 billion. For whatever reason your pattern could repeat alot, or not at all, and only other patterns have repeated. 🤯
this is wrong.. this is simple accounting the probability, but it doesn't account for the time and materials needed for this to occur.
It's impossible to run into an exact copy of yourself, because they are unknowingly moving further away from you at the same rate you're moving closer to them. From your perspective you'd simply be back where you started, even though your surroundings are (unnoticeably) different
You could run into an exact copy of yourself that’s been turned around, although those odds are probably still pretty bad.

i think that's a really cool idea, but i dont really like how he keeps saying "if you go far enough". the point is that there could be an exact replica of me on earth right now, its mathematically POSSIBLE however unlikely. he is pointing out that if the universe were that big, my double would pretty much be a mathematical certainty. it's a really cool idea, but its not like there is a specific distance you would have to travel to find your double. i guess technically traveling would increase the number of arrangements matching your approximate mass thus increasing the chances of you FINDING your double.... but traveling in one direction i don't think would guarantee you would find that particular arrangement in such a vast universe
This is so interesting
I had muted the video but instantly knew this guy was British and also knew exactly what he sounded like.
In response to Jakka Makka: "how is a particle larger than a grain of sand?"
It is not, he was counting the total number of particles in the universe, not the number of particle you could fit. There is space between particles.
Just wondering .. how can you say that the universe is 10^26m?
assume there's a number that is 1, every planck time it doubles, how much time is required for it to become a googolplex?
So we're looking for 2^x = 10^googol, and by taking the log2 of both, we get x = googol * log2 (10), or approximately 3.32 googol (that's 3.32 * 10^100)
3.32 * 10^100 planck times * 5.85 * 10^-50 years per planck time = 19.4 * 10^50 years (more properly rewritten as 1.94 * 10^51)
That's 194 trillion trillion trillion trillion years, or 14,160 trillion trillion times the current age of the universe.

The problem I see with taking the possible number of quantum states of a give volume being less than a googolplex to indicate potential duplication of an individual is that it assumes the configuration to be entirely random, and doesn't account for the probability of the necessary chemical reactions to produce that state.

"It wasn't a big number at all, compared to infinity." This is true for ALL numbers, isn't it?
Well base knowledge wise he meant as Googole and googoleplex have an ending no matter how big it is but infinity it just keep going numbers Increase more and more so infinity is big so big it practically never ends numberwise.
It all just based on how we categorised the numbers in a bunch
Carl Sagan taught me this in 1980.
I had multiple aneurysms reading all these comments and replies
This got me thinking about intuitionistic mathematics and their problems with infinity... If we established a number that could represent all possible states of the universe, would this settle down a conflict between classic and intuitionistic math?
By the way, could you guys make a video on intuitionism vs. formalism vs. logicism? I believe it to be a really interesting topic.
Thank you for this channel!
Somebody messed up. If 10^80 = number of particles in universe then 10^90 couldn't possibly be the number of sand grains to fill it. There is no way in hell that's accurate, like, at all, not even remotely close.
Its because most of the universe is actually empty space so if u fill the universe with grains of sand (that obviously contain particles) then it would be larger and have more mass and a higher density
except that particle aren't arranged by chance, I suspect you would run into many more empty cubic meters or meters filled with other elements before you ran into a copy of anything more complex just by chance
Astonished every second of this video.
The number for these repetitions must be significantly smaller, since that was based on possible quantum states. For example, in a large enough universe, a person could be naturally formed by evolution much more commonly. And if there was a copy of you that had a small scratch in an arm, that wouldn't be accounted for in the calculation either.
This seems to imply that every possible arrangement of particles only occurs once in the Universe, not taking into account the relative probability of different states. :| Obviously, most f it is void or simple gases (Dark M&E aside), while more complex structures like living beings are less frequent. It could conceivably be a googolplex of nothingness.
If i would have 1 googolplex € or $ .....i would buy an ice cream

Idk why but just seeing him Antonio smile makes my day
The notion of "this is how many possible quantum states the stuff that you are made out of could be in, therefore it's a 1/(that number) chance of it being you" isn't quite sitting right with me.
It sort of implies that certain quantum states aren't preferred.
And I don't know if this is true.
+Otrakun If assumed that some states are preferred then the number will be smaller. Either way his logic is fine.
imagine googleplex to the power of graham's number :D
Elementary, lol
Still probably smaller than tree(3)
Googolplex is literally NOTHING compared to Graham's number (the size of that truly is beyond any kind of real comprehension)
Or, how about TREE(googleplex^Graham's Number)
Imagine 3(Tree) to the power of 3(Tree) 3(Tree) amount of Arrows between, to the power of 3(Tree) 3(Tree)Times. Etc etc
This conclusion seems wrong. Just because there are 10^10^70 different states available doesn't mean that every meter is some random combination of atoms. There are huge pieces of space where the state is almost identical for long stretches.
+
That's what I was thinking too :) but I believe he presented it that way so that we can imagine how impressive the number is, but most of the universe is empty space ^^ (sorry if english mistakes)
I think the assumption is that you'd have an observable universe with particles in it to match the scaled up size. Otherwise you'd reach the end of our universe, the extent of the expansion of space from the original singularity and simply have emptiness.
Which makes it even more likely. We know that the universe isn't some random number generator, and typically things happen for reasons, albeit chaotic reasons. This means that, because the universe is rule-bound, it would be far more likely than the chance mentioned in this video that you'd find a copy of yourself somewhere in a universe that large.
Think of it as a dice with 10^10^70 sides. If you rolled it 10^10^100 times, you would expect to see at least one roll of the same number. Of course, it's not even possible for you to not get the same number twice. You would get 10^10^30 (I think) duplicates. FOllow me?
This video gives me a lot of nostalgia of what the internet used to be
I think I can think of an even bigger number.

That is the reason why you are big enough to occupy just enough volume, that you won't find a copy of yourself in observable Universe.
Counting to a trillion (1,000,000,000,000) can take less than 3 mins!
If everyone on earth could count to 135 at the same time. (world population: 7.3 billion, it's like counting to 7.3 billion per sec) Imagine all living things on earth (including: humans, animals, and other species) all together about trillions (just guessing not sure thou) if all trillion of us counted to 1 million at the same time we can reach 10^18 in less than a 2 weeks. But googol is just so freaking massive 10^18 is only 0.000000000000000000000..1% of a Googol (10^100)

1,000,000,000,000,000,000 = trillion
That's long scale and look Tony Padilla from Nottingham University uses it even though he's British, where short scale is predominant. It's important to know both scales if you travel even around the Europe. But in science they use long scale. Same as SI. Which sometimes causes problems in international conventions when USUALLY mathematicians, and physicist with so so knowledge of English will read something in short scale and have to apologize and say it in a long scale, same for scientist from British and American societies, sometimes they slip up (Americans tend to do it more often, it's more imbedded in their Uni life.
