All of the comments pointing out that people learn this in 6-9th grade are missing the point. Almost EVERYTHING Derek makes videos on is taught at some point in the education system, but people either forget it or have a fundamental misunderstanding. He's not trying to teach graduate level information. He's trying to correct the foundation that so many people have built upon sand.
+Mike Garner Actually, there are people that don't know this things! including me. So it does teach some people. Some people may learned it already some dont.
I see you've been watching numberphile... All good points but the number of protons is not just over half of a googol - it's much much less. Just as 10^2 is not half of 10^4 (it's 1%)
I love this video, and have shown it to my students every year when I teach scientific notation. I teach 5th grade. It's not only highly informative, but fun to watch. :-) THANKS!
I used i diferent way to get that answer, frist i calculate the numbers of the protons in 1kg after that just multiple by the mass of the sun and get the answer. 1.195457262 * 10^57 :D
I recommend this video to all my students, coming from all over the world, good private schools, all my students who do not have the habit of using the scientific notation. Thank you, Veritasium!
Interesting videos. And the ones where he explains subjects are really well done. He makes this subject easy to understand and use. Chem. is going to be a lot easier tomorrow. Thanks!
Love your video and many high schoolers need this too. Great job explaining. So I teach at an alternative high school and many of my student's traditional teachers gave up on them years ago and just ignored them. They need as much support as possible. This will help .a lot.
Your videos are so awesome man! An easy-way to understand basic fundamental facts that means to be known, and you make it soooo funny!! ahaha thanks dude!
I think the carrot notation is pretty much the standard exponent delimiter in plain text. It could also be written as 2 * 10^30 or 2(10^30) in algebraic exponential notation, or 2e+30 in IEEE standard exponential notation.
I didnt need to watch this because i already know scientific notation. I watched it because it being a veritasium video i knew it'd be awesome. And the intro so is!!
now i learned a ton of this great video and after a decade i answer your challenge question i asked how many protons would be in 1 kg or how many (1.673 x 10 to the power of -27) are in 1kg based on this equation ( 1 / 1.673 x 10 to the power of -27) = 5.977286312 x 10 to the power of 26 that is how many protons would be in each 1 kg of the sun so multiply that number by the sun's number of kilograms which's (2 x 10 to the power of 30) and that equals (1.195457262 x 10 to the power of 57) protons holly crap i may have just gotten this right!
(2/1,673)*(10^30/10^(-27)) And if you have 10/(1/10) you just multiply 10 by the reciprocal value of (1/10) Wich is 10. So you can just add 30 to 27 so you have: (2/1,673)*10^57 Wich is roughly 1,1955*10^57 [Protons]
The internet is your friend. There's such a vast wealth of knowledge held within this revolutionary plane that you can master any and everything education has to offer.
The masses of subatomic particles are usually given in eV, electron volts, or u, atomic mass units, which are the energy exchanged by moving an electron trough a one volt potential, 1.60 × 10e-19 j or 1.78 × 10e-36 kg, and one twelfth the mass of a carbon twelve atom,1.49×10e-10 j or 1.78 × 10e-36 kg. In these values a proton has a mass of approximately 1 u or 1 GeV. The mass of the sun is measured in mass of the earth or in mass of the sun that is 3.32 ×10e5 Earth Masses or 1 Solar Mass.
@1veritasium I think the reason they prefer one number in front of the decimal place is because they used to do all their calculations on slide rules which had to have one digit in front of the decimal place to work.
This video really enlighted me about the scientific notation I 'learned' from school. I think that was for me what you said music meant to you for about 2 years, hehe :/
that's where computers (and calculators) come in. On the paper/blackboard you can write the less accurate number for convenience, but store the more accurate one on a computer or in your calculator for when you want to use it. This way you have the best of both worlds: concise working and accurate results.
+agent475816 Problem is there are different elements with different numbers of neutrons, protons and electrons. Only way to somewhat accurately figure it out is to know the % of each element in the sun. Best way hypothetically is to just say the entire mass of the sun is hydrogen, find out how many hydrogen atoms it takes to produce the suns mass and then multiply the mass of 1 proton by the number of atoms.
I don't know why I watch this even though I already know it (but i understand that not everyone learned it), it just feels good to watch it anyway, maybe it just makes me feel smart.
@@harvingaming3203 He's just doing the math Derek asked him to do at the end of the episode. Using the figures given, the Sun has a mass of 2×10³⁰ kg, and a proton has a mass of 1.673×10⁻²⁷ kg, so if we want to know how many protons would have a mass equal to the Sun's, we just divide, and using the fundamental property of exponents, find that the sun has as much mass as (2×10³⁰ kg)/(1.673×10⁻²⁷ kg) = (2/1.673)×10³⁰⁻⁽⁻²⁷⁾ = (2/1.673)×10³⁰⁺²⁷ = (2/1.673)×10⁵⁷ protons. Finally, using a calculator or long division to divide 2 by 1.673, we get about 1.195, yielding the answer of 1.195×10⁵⁷ protons. If Firaro had just looked up the answer, he would have found that the Sun only really contains 1.058×10⁵⁷ protons. The difference is mostly due to the fact that the Sun also contains a large number of neutrons (almost all of which are in the nuclei of helium and deuterium). So Firaro didn't search for the answer. He calculated it like the video asked and got the right answer.
1.) What is the large number representing? Hint: it was the mass of something very large in our solar system 2.) what was the small number representing? Hint: it’s part of a molecule Can you guys help me with those questions?
I see all the comments talking about," hey derek why not do better content", or, "hey derek you should've talked about ________". Well to keep in mind, he did make the video 4 (almost 5 years ago) and around this time he may have been experimenting with different video ideas--perhaps whether he wanted the channel to be educational and factual, or philosophical in terms of physics (so that when you finish a video you are left with a question on top of an answer). For those who wonder if he has made better content, yes. Yes he very much has, so much to the point that this comment does not do justice to the content that he has uploaded going as far and vast as the regular mechanics of our planet, to the physics that make up the planet, the physics that make up the particles that make up the planet. I've only been a recent subscriber but there are tons, (TONS) of information on this channel, if there is a complaint about the content he has made or if you feel unsatisfied with what he has posted, most likely you haven't seen the rest of his channel because the diversity and depth of his uploads will change your mind.
thank you sir.....now i am not having any confusion......i wish that you may make video like this only...which would be helpful for the students like me
Becuase Kilograms is an Unit in the International systematic system. Called the SI units, designed to be usefull in most formula's without all kinds of constants with factors of 1000, 10 or something.
One half of a Googol would be 5x10^99. 1.195x10^57 is smaller than a Googol by a factor of about 8.37x10^42, or 8 times a million trillion trillion trillion. And as for printing 0's onto particles, there are about 1x10^80 particles in the observable universe, which would mean 1x10^80 zeros printed out of the 1x10^100 needed. You would in fact need 1x10^20 universes or 100 million trillion universes in order to have a Googolplex particles.
NO! Sorry to tell you that. 1e+57 or the long number the other guy said are BOTH CORRECT! I checked out your mentioned video before and it doesn't matter. I know too much of these things already. :) The point is that you can use them in the way you want to, to implement what you want. But you can't say others way of saying the same thing is wrong just because you expect them to do the same thing like I said before :) So both are correct, your way of saying it is just better :D
Fine explenation and all.. But I'm still waiting for the moment where you are going to explain why it also is used to round down answers or any number given at all, to the point with an appropriate marge.
The first part is actually incorrect, you must remember that the exponents represent entirely new digits so that makes each exponent 10x larger than the last. Shrink the number down to 1.195*10^5.7 vs. 1x10^10 and you get 598918.7 (rounded to the nearest 10th) vs. 10000000000, the difference between the two numbers is 9999401081.3 (rounded again) which even the difference is much much larger than the original 10^5.7.
There isn't a prefix high enough to represent the mass of the sun (2000Yg), nor low enough for a proton (0.001673yg). Plus, it's easier to just do the exponent arithmetic than memorize which of the 20 prefixes refers to which factor of 1000.
@Daniel Sultana I needed to check my scientific notation science hw once and while googling the answer the product also involved the letter 'e' I guess its a science for scientifit notation. But there is also a number thing call 'e' there are also i, and f
Everyone should naturally know this. You just have to divide the weight of the sun by the weight of a proton. So you add the absolute value of the exponents and multiply it by the significant digits bevor the comma. In my mind you can´t even read a cooking book without knowing this, so it should be general knowledge. But well, maybe there are some who didnt know :)
The explanation might be even clearer if you said the positive exponents indicate the number of places you shift the decimal place to the left and the negative exponent indicates the number of places you shift the decimal point to the right.
Well, actually 3, in 10^3, would be the power and 10 would be the base. So "ten to the power of three" would be correct, and I also believe that other two ways you have stated are correct too.
It should also be noted that the writing the mass of the sun like that, that you're implying that it's EXACTLY that number, which is highly unlikely. Writing it abbreviated also gives you the sense that there might be some smaller numbers there, and you aren't implying an accuracy you don't know. This is also the same way as floating point numbers are stored in computers, to make sure huge numbers don't take up huge space.
Lol I just watched the video because I thought that in 5 minutes of such a known and simple subject there was something bit more complicated behind scientific notation that I didn't know lol, but nah you just took your time explaining :P.
Try and think smaller 10:1000 or 10^1:10^3. We may assume that it's 3x larger, but in reality 10^1 is 1% of 10^3, 10^2 is 1% of 10^4, 10^4 is 0.01% of 10^8, 10^5 is 0.00001% of 10^10. So you can see that the difference in size begins to become exponential when comparing exponents that double in size.

Protons, Am I right?
But that would be assuming the sun is entirely made of hydrogen, hence it would have only protons in it. But there is also helium in it, which contains both protons and neutrons which have the same mass. (And there are also other materials created through fusion which can be ignored due to their relatively small amount.). So really the sun has the amount of hydrogen atoms plus half the amount of helium atoms worth of nucleons. It does have 3.346*10^57 nucleons though.
Timothy Brantley Yes, Yes you are right, however he has pointed out the confusion. In fact I have that as well that I forget a number or write a different number that shouldn't be the answer, just because my brain flipped between multiplication and exponential formulas.
for reason that it will work with any number and you don't have to count or remember the numbers after the first non-zero number lets say we have a number 1.12478565478877455665 x 10^-30 this is easier than 112478565478877455665 x 10^-50 in which case you have to count not only zeros but the numbers following the first number too and add it to the exponent so you are doing useles work by writing it down that way - it means more possible mistakes in the counting and that's not preferable.
All of the comments pointing out that people learn this in 6-9th grade are missing the point. Almost EVERYTHING Derek makes videos on is taught at some point in the education system, but people either forget it or have a fundamental misunderstanding. He's not trying to teach graduate level information. He's trying to correct the foundation that so many people have built upon sand.
+Mike Garner Actually, there are people that don't know this things! including me. So it does teach some people.
Some people may learned it already some dont.
i agree with you. thanks for your opinion mike garner
+
I agree with you.
Mike Garner jjjj
I see you've been watching numberphile... All good points but the number of protons is not just over half of a googol - it's much much less. Just as 10^2 is not half of 10^4 (it's 1%)
Hi
No. Of protons in sun would be 1.19545726e50 !!!!!
@@harshrivastava08 I'm laughing at the insignificant numbers included in the calculated guesstimate. 1.2e50
Sir you are great
I am in class 9
And it helps in remembering the size of proton it's 1.673 into 10 raised to the power minus 27
Thank you 😊
Yes sir👍
I love this video, and have shown it to my students every year when I teach scientific notation. I teach 5th grade. It's not only highly informative, but fun to watch. :-) THANKS!
This is a great RUclips channel keep it up Derek!😁
(2.0 x 10^30) / (1.673 x 10^-27) =
(2.0 / 1.673) x (10^30 / 10^-27) =
1.195 x 10^(30- -27) =
1.195 x 10^57 protons
yay math!
moosefarms I think all these "1.25" answers are coming from diving 2 by 1.6 instead of 1.673...
I used i diferent way to get that answer, frist i calculate the numbers of the protons in 1kg after that just multiple by the mass of the sun and get the answer. 1.195457262 * 10^57 :D
You forgot parenthesis before "-27", it's "30 − (−27)", not "30 − −27".
P.S. I know, I'm being pedantic, but I'm right as well. :D
you are totally correct. whoops
Giorgi Gzirishvili I was going to say...but glad you pointed that out.
I recommend this video to all my students, coming from all over the world, good private schools, all my students who do not have the habit of using the scientific notation. Thank you, Veritasium!
This was a good video. THIS is what RUclips should be about. Well done.
@BAR2Q12 Sure - it would be unconventional but you could do it. Scientists prefer one digit in front of the decimal place for some reason.
Hello
LOL for the comment "Can you repeat that?"
wait wdym can you repeat that?

MY MATH TEACHER JUST TEACHED THIS TO US AND SHOWED THiS VID AND mE AT SCHOOL WAS LIKE
ME: VERITASIUM!!!! I KNOW THAT GUY
*taught

You're so Lucky mannn
The mass of the sun = America's nation debt - 1
Oh yeah i forgot the universal exchange rate from mass to dollars is so large xD
Interesting videos. And the ones where he explains subjects are really well done. He makes this subject easy to understand and use. Chem. is going to be a lot easier tomorrow. Thanks!
Why couldn't you have been my teacher when I was learning this stuff in high school? lol
Love your video and many high schoolers need this too. Great job explaining. So I teach at an alternative high school and many of my student's traditional teachers gave up on them years ago and just ignored them. They need as much support as possible. This will help .a lot.
Your videos are so awesome man! An easy-way to understand basic fundamental facts that means to be known, and you make it soooo funny!! ahaha thanks dude!
Mr. Muller, you truly have a thing for this...amazing explanation and GREAT humor😂. Keep it up!👏🏻👍🏻
Brilliantly explained. Thanks a lot! This can be directly used as example for teaching confused kids the beauty of exponents.
I think the carrot notation is pretty much the standard exponent delimiter in plain text.
It could also be written as 2 * 10^30 or 2(10^30) in algebraic exponential notation, or 2e+30 in IEEE standard exponential notation.
Im a 5th grader
and thats helps SOOO Much with math work in school THANKS =)
Wat
@@Scubuah are you speaking English?
Are you now a 10th grader? It has been 5 years
@@axf-22 he is in 11th grade now haha
wait, you learn scientific notation in 5th grade
This actually helped me understand this a lot better thanks.
When this video was made I wasn't even 1 years old, now I'm watching to help me for my math exam
I didnt need to watch this because i already know scientific notation. I watched it because it being a veritasium video i knew it'd be awesome. And the intro so is!!
watching in 2023 big fan of your work muller.❤❤❤❤❤❤❤🎉🎉🎉
0:45. I just died with that level of cuteness. Sorry Dr.
Guilty as charged
That's why we're here
I believe it makes it simpler for keeping track of significant figures in some cases.
Although I still think that the terminology of 10^30 as "multiply 10 by itself 30 times" is ambiguous, you have explained it very well thank you!
Very amazing video as a pioneer video for a scientific youtube channel!
now i learned a ton of this great video and after a decade i answer your challenge question
i asked how many protons would be in 1 kg
or how many (1.673 x 10 to the power of -27) are in 1kg
based on this equation ( 1 / 1.673 x 10 to the power of -27) = 5.977286312 x 10 to the power of 26
that is how many protons would be in each 1 kg of the sun so multiply that number by the sun's number of kilograms which's (2 x 10 to the power of 30)
and that equals (1.195457262 x 10 to the power of 57) protons
holly crap i may have just gotten this right!
hell yeah
You're wrong, try again, maybe come back in another decade.
Love it! Home schooling a 9th grader and a mama needs some reminders. Thanks for making it fun!
(2/1,673)*(10^30/10^(-27)) And if you have 10/(1/10) you just multiply 10 by the reciprocal value of (1/10) Wich is 10. So you can just add 30 to 27 so you have: (2/1,673)*10^57 Wich is roughly 1,1955*10^57 [Protons]
1.19 × 10^57
in my language its known as potens. love how easy multiplication and division is if both are the same first number
Back to the future Derek 🚗
I've been in school for 11 years and have never been taught or even heard of the word scientific notation till now
Damn, that school must suck!
The internet is your friend. There's such a vast wealth of knowledge held within this revolutionary plane that you can master any and everything education has to offer.
one of my favorite things about scientific notation is that it works in all bases :)
1024 = 0b1 x 0b10 ^ 0b1010 = 0b10000000000
binary ftw
Did you just unknowingly explain floating-point numbers
Wow! Thank you! You have made scientific notation easy for even the youth!
Not as exciting as your standard videos, HOWEVER priceless when I am teaching Sci Notation.
this was one of his first videos.
Veritasium I want you as my science teacher next year
Get on that
The Fox Laboratory is he yet?
AllGamesConsidered nope I got some random shitty teacher

The masses of subatomic particles are usually given in eV, electron volts, or u, atomic mass units, which are the energy exchanged by moving an electron trough a one volt potential, 1.60 × 10e-19 j or 1.78 × 10e-36 kg, and one twelfth the mass of a carbon twelve atom,1.49×10e-10 j or 1.78 × 10e-36 kg. In these values a proton has a mass of approximately 1 u or 1 GeV. The mass of the sun is measured in mass of the earth or in mass of the sun that is 3.32 ×10e5 Earth Masses or 1 Solar Mass.
Dude you're a good teacher
@1veritasium I think the reason they prefer one number in front of the decimal place is because they used to do all their calculations on slide rules which had to have one digit in front of the decimal place to work.
@creektimothy my guess would be yes.
Came here from 2023, just to tell you
You are a true legend
This video really enlighted me about the scientific notation I 'learned' from school.
I think that was for me what you said music meant to you for about 2 years, hehe :/
looking to start my own channel, interesting to see your development ! just here reviewing your old vids !
1.20x10^57 protons (3 significant figures)
A truly tiny number.
Electron: *no*.
that's where computers (and calculators) come in. On the paper/blackboard you can write the less accurate number for convenience, but store the more accurate one on a computer or in your calculator for when you want to use it. This way you have the best of both worlds: concise working and accurate results.
Finally a video veritasium video I can keep up with
2 x 10^30 kg / 1.673 x 10^-27 kg = 1.195 x 10^57 protons in the sun.
The sun isn't (only) made out of protons. Also Neurtons and electrons
שגיא קרמן True. I guess that's the number of protons and neutrons.
+שגיא קרמן It's hypothetical.
the sun is just not protons.
+agent475816 Problem is there are different elements with different numbers of neutrons, protons and electrons. Only way to somewhat accurately figure it out is to know the % of each element in the sun. Best way hypothetically is to just say the entire mass of the sun is hydrogen, find out how many hydrogen atoms it takes to produce the suns mass and then multiply the mass of 1 proton by the number of atoms.
Wow I was boutta fail math but not anymore, this video is truly eye opening thnx 👁👄👁
I don't know why I watch this even though I already know it (but i understand that not everyone learned it), it just feels good to watch it anyway, maybe it just makes me feel smart.
1.195 x 10^57 protons if the sun was composed only of protons
when u search something up and think ur smart
@@harvingaming3203 He's just doing the math Derek asked him to do at the end of the episode. Using the figures given, the Sun has a mass of 2×10³⁰ kg, and a proton has a mass of 1.673×10⁻²⁷ kg, so if we want to know how many protons would have a mass equal to the Sun's, we just divide, and using the fundamental property of exponents, find that the sun has as much mass as (2×10³⁰ kg)/(1.673×10⁻²⁷ kg) = (2/1.673)×10³⁰⁻⁽⁻²⁷⁾ = (2/1.673)×10³⁰⁺²⁷ = (2/1.673)×10⁵⁷ protons. Finally, using a calculator or long division to divide 2 by 1.673, we get about 1.195, yielding the answer of 1.195×10⁵⁷ protons.
If Firaro had just looked up the answer, he would have found that the Sun only really contains 1.058×10⁵⁷ protons. The difference is mostly due to the fact that the Sun also contains a large number of neutrons (almost all of which are in the nuclei of helium and deuterium). So Firaro didn't search for the answer. He calculated it like the video asked and got the right answer.
1.) What is the large number representing? Hint: it was the mass of something very large in our solar system
2.) what was the small number representing? Hint: it’s part of a molecule
Can you guys help me with those questions?
I see all the comments talking about," hey derek why not do better content", or, "hey derek you should've talked about ________". Well to keep in mind, he did make the video 4 (almost 5 years ago) and around this time he may have been experimenting with different video ideas--perhaps whether he wanted the channel to be educational and factual, or philosophical in terms of physics (so that when you finish a video you are left with a question on top of an answer).
For those who wonder if he has made better content, yes. Yes he very much has, so much to the point that this comment does not do justice to the content that he has uploaded going as far and vast as the regular mechanics of our planet, to the physics that make up the planet, the physics that make up the particles that make up the planet.
I've only been a recent subscriber but there are tons, (TONS) of information on this channel, if there is a complaint about the content he has made or if you feel unsatisfied with what he has posted, most likely you haven't seen the rest of his channel because the diversity and depth of his uploads will change your mind.
Most meaningful and knowledgeable videos
thank you sir.....now i am not having any confusion......i wish that you may make video like this only...which would be helpful for the students like me
Becuase Kilograms is an Unit in the International systematic system. Called the SI units, designed to be usefull in most formula's without all kinds of constants with factors of 1000, 10 or something.
thanks man it helped alot
i got a good grade on my exam hanks man
탄기운 Tv ikr its helpfull
Thanks please teach me more because I not good at mathematical 😢
THANKS BRO! Now im sure ill get a good grade on my test. Thanks!
3:05 First time I've seen someone writing zeros that fast
Double speed
It was sped up.
I wish my homework was this simple...
@BAR2Q12 it's easier to have that 1 digit to the left of the decimal since your exponent will be just how many zeros you'll be needing.
THANK YOU SO MUCH!!!!!! This helped me so much! yay!
One half of a Googol would be 5x10^99. 1.195x10^57 is smaller than a Googol by a factor of about 8.37x10^42, or 8 times a million trillion trillion trillion. And as for printing 0's onto particles, there are about 1x10^80 particles in the observable universe, which would mean 1x10^80 zeros printed out of the 1x10^100 needed. You would in fact need 1x10^20 universes or 100 million trillion universes in order to have a Googolplex particles.
I finally get it. Thank you.
you explain this much better than math antics
Great lesson Derek !! I loved that ❤🖒
NO! Sorry to tell you that.
1e+57 or the long number the other guy said are BOTH CORRECT!
I checked out your mentioned video before and it doesn't matter. I know too much of these things already. :)
The point is that you can use them in the way you want to, to implement what you want. But you can't say others way of saying the same thing is wrong just because you expect them to do the same thing like I said before :)
So both are correct, your way of saying it is just better :D
Fine explenation and all.. But I'm still waiting for the moment where you are going to explain why it also is used to round down answers or any number given at all, to the point with an appropriate marge.
Quote: "If the sun were made completely out of protons [...]"
The first part is actually incorrect, you must remember that the exponents represent entirely new digits so that makes each exponent 10x larger than the last.
Shrink the number down to 1.195*10^5.7 vs. 1x10^10 and you get 598918.7 (rounded to the nearest 10th) vs. 10000000000, the difference between the two numbers is 9999401081.3 (rounded again) which even the difference is much much larger than the original 10^5.7.
Good explaination ......
There isn't a prefix high enough to represent the mass of the sun (2000Yg), nor low enough for a proton (0.001673yg). Plus, it's easier to just do the exponent arithmetic than memorize which of the 20 prefixes refers to which factor of 1000.
it's called shorthand in the UK.
No of protons would be
Approx 1.195× 10^57
dude THANK YOU SO MUCH
ur vids helped me realize im not stupid thank you so much!!!!
@Daniel Sultana I needed to check my scientific notation science hw once and while googling the answer the product also involved the letter 'e' I guess its a science for scientifit notation. But there is also a number thing call 'e' there are also i, and f
tnkx a lot! now I know! u explained it well! good job!😁
Everyone should naturally know this.
You just have to divide the weight of the sun by the weight of a proton.
So you add the absolute value of the exponents and multiply it by the significant digits bevor the comma.
In my mind you can´t even read a cooking book without knowing this, so it should be general knowledge. But well, maybe there are some who didnt know :)
The explanation might be even clearer if you said the positive exponents indicate the number of places you shift the decimal place to the left and the negative exponent indicates the number of places you shift the decimal point to the right.
Well, actually 3, in 10^3, would be the power and 10 would be the base. So "ten to the power of three" would be correct, and I also believe that other two ways you have stated are correct too.
Yes, but he was referring to the "1" being followed by 2 zeroes.
It should also be noted that the writing the mass of the sun like that, that you're implying that it's EXACTLY that number, which is highly unlikely. Writing it abbreviated also gives you the sense that there might be some smaller numbers there, and you aren't implying an accuracy you don't know. This is also the same way as floating point numbers are stored in computers, to make sure huge numbers don't take up huge space.
Lol I just watched the video because I thought that in 5 minutes of such a known and simple subject there was something bit more complicated behind scientific notation that I didn't know lol, but nah you just took your time explaining :P.
Thank u so very much for making this video i was needing that soooo much
Try and think smaller 10:1000 or 10^1:10^3. We may assume that it's 3x larger, but in reality 10^1 is 1% of 10^3, 10^2 is 1% of 10^4, 10^4 is 0.01% of 10^8, 10^5 is 0.00001% of 10^10.
So you can see that the difference in size begins to become exponential when comparing exponents that double in size.
Thanks alot
Does that also mean that 10^2 = Ten times itself 2 times? Which would be 10x10(first time)x10(second time)?
I saw ur story on fb and came to this video and its strangely like a time travel 😧

Really? that many o's
Wrong. It has (1.195 x (10^57) ) protons. Which means is has 1195 followed by 54 zeros number of protons.
To sum up, 2x10^30/1.673x10^-27 is 1.1954573x10^56
But that would be assuming the sun is entirely made of hydrogen, hence it would have only protons in it. But there is also helium in it, which contains both protons and neutrons which have the same mass. (And there are also other materials created through fusion which can be ignored due to their relatively small amount.). So really the sun has the amount of hydrogen atoms plus half the amount of helium atoms worth of nucleons. It does have 3.346*10^57 nucleons though.
Awesome video, thanks
"Ten to the power of four..."
(writes fourteen)
So. Damn. Often.
2^3 is not the same as 2 times 3. (Which is six) 2^3 really means 2 multiplied by itself 3 times. 2*2=4 4*2=8.
Timothy Brantley Yes, Yes you are right, however he has pointed out the confusion. In fact I have that as well that I forget a number or write a different number that shouldn't be the answer, just because my brain flipped between multiplication and exponential formulas.
for reason that it will work with any number and you don't have to count or remember the numbers after the first non-zero number
lets say we have a number 1.12478565478877455665 x 10^-30 this is easier than
112478565478877455665 x 10^-50 in which case you have to count not only zeros but the numbers following the first number too and add it to the exponent so you are doing useles work by writing it down that way - it means more possible mistakes in the counting and that's not preferable.
the answer is 1x10^57 (rounded to the significant number)
This homeschooling Mom thanks you!
So helpful! thanks
Lol
It looks like a video about significant figures may be called for :)
