Why are Significant Figures Important?

[@hurricanejay1777]

BLESS YOU THERE IS A SPECIAL PLACE IN HEAVEN FOR PEOPLE LIKE YOU WHO MAKE SENSE WHEN THEY EXPLAIN THINGS

[@yashia96]

I am Muslim and you can say things in a better way. Only Allah Swt accepts who will go to heaven not us.. In Islam, we do not even know if we are going to heaven 100% so we should be people to strive in the way of the truth.

[@LordBlob1]

I can't believe people still believe this xD

[@debmalyabiswas1264]

Bilal Younas Such a primitive mindset..... Ashamed of you

[@hurricanejay1777]

Agh wait no I made this comment to appreciate Tyler and his teaching not to spark a debate on religion

[@flaymien_2450]

Bilal Younas - Idiotic, mindless, unrealistic, and self-oriented people like you are the reason Islam has such a bad name today. You should take that offensive and controversial comment down. By the way, I'm a Muslim and I literally was embarrassed and ashamed to to see someone say something that awful. All the hate for our religion is better justified than the reasoning for our decisions on what to say and do when it comes to people like you. In the Qur'an it states that all people will be judged based on the righteousness of their decisions during life, not purely their religion.

[@ethanferrer1577]

This man single handedly carried me through high school when my teachers would get mad at me trying to explain everything. Thank you so much.

[@tdewitt451]

Stop moving my hands? Sorry, not gonna happen. But I'm really happy that you found this video useful.

[@debmalyabiswas1264]

You don't need to! Thanks Tyler DeWitt

[@youre_totally_right_but_]

You're amazing and I love your videos so much!

[@shriyasharma7688]

SIR THANK YOU FOR MAKING THESE INCREDIBLY USEFUL VIDEOS :) LOVE YOU SO MUCH!

[@Ryan.Gosine]

gesticulation is a virtue

[@TigistGebeyehu-gz5nq]

I think it is more about how the answer would be correct if you use significant number to make the answer less precise , becouse if you start with less precise numbers they are most probalbly round up at first place from their precise form so when you calculate these rounded numbers you must make the answer less precise to make sure its more correct than the unprecised answer.

[@chemtea7030]

Hi, Tyler DeWitt , I am a chemistry lecturer from India. I really like all your videos on Significant figures. Great job ! It has clarified some of the FAQs of my students and mine too !! Thanks again, keep up the good work !

[@onur9657]

11 years later you are still a legend. All your significant figures videos are great!

[@thegoodsoilsharvest]

Thank you for taking time out of your life to put up all these amazing videos for helpless students. You are my hero!!

Finally found a good explanation of the why behind significant figures. Awesome explanation, thank you.

[@tdewitt451]

I'm so happy you liked it! This is one of the my favorite videos that I've ever made!

[@somedude8604]

"I measured both of these with plastic science equipment from the Barbie playset" Gets me every time.

[@heelFLiP249]

Thank you so much my teacher was trying so hard to explain this to me but I just wasn't getting it. I watch this and it immediately makes sense!!

[@hovhadovah]

Your analogy is brilliant. Really made this concept click for me--I only wish teachers could explain it as easily and clearly as you did...then we could all avoid the headache of students complaining that this concept doesn't make sense. Teachers set themselves up for failure when they present sig figs as this obscure and bizarre concept that no one understands. Thanks so much for this video!

[@boobalarasuvelu9804]

Hats off Tyler. My 30 years of failure in understanding this concept was done straight after seeing these 10 simple, excellent and extraordinary video clips. You are a Star. You are a light.

[@ehazgro10]

Loved the analogy

[@FusionDeveloper]

That is really funny. I will never forget this because it is very logical.

[@tdewitt451]

Thank you! This is one of my favorite videos that I ever made!

[@FusionDeveloper]

Tyler DeWitt This video taught me something I had never even thought about. Thank you for contributing your knowledge to KZbin as free education.

[@Demitrival]

I’m very sensitive, but your passion for educating made me tear up at the end of the lesson. Thank you for your help!

[@salmagamal5728]

From Egypt, really I didn't find anyone explaining so wonderfully like that I hope you continue to Download videos

[@maahasgharali571]

Oh my god, you are the best. today when I went to my physics class and didn't get the explanation, I wasn't procrastinating as I knew about your channel before and also that u must have made a video on significant digit already. now I can confidently walk in class as your lesson made everything crystal clear. one more thing I also really like the way your video are format, they seems so professional, Keep up the good work.

[@SB-bh4of]

Extremely helpful explanation that even an idiot like me could grasp. Just starting a science degree and this helped a lot, thank you.

[@vittoriobenedet2221]

jesus!! thanks god for the last video. i ve seen all the nine videos before in a raw getting pissed off for your different approach. and than, here you are again in the last one with the same effective method ; making examples, making me care, showing the point. every teachers in the world should learn how to teach like this, especially here in italy. I THINK WOULD BE EVEN BETTER IF YOU TAUGTH TEACHERS HOW TO TEACH!

[@sourabhkumar1172]

Many chemistry teachers came in my life but it's only you who has satisfied me 🙏

[@Hawkent]

Explained it better than any teacher I'd ever had. Thank you so much.

[@lianner15]

wow. thank. you. I FINALLY UNDERSTAND WHY IT MATTERS!!! I asked my college professor to explain this and he wasn't able to explain it in an hour lecture... as great as you did in 7 minutes.

[@rohit20233]

Thanks, u r such a good teacher, u r better than my highly graduated chemistry and maths teachers, love from india

[@gerry6144]

Explains everything beautifully. A born teacher.

[@808thampire]

Wow finally sig figs make sense! Thanks!

[@Basic-Tron]

Great analogy man, thanks. Helped a lot!

[@christopherzhang2576]

This is an A+ example of a well-explained video. Keep up the great work!

[@THEAPEXACADEMYOFMATHEMATICS]

I was creating my first videos on KZbin and I met you for the first as a math student and student tutor.... And honestly not explanation is off the chain.... Awesome job bro

[@tamarnorquist3671]

Finally a video where someone explained the IDEA of sig figs! -- A Chem teacher looking for support materials for students

[@Unosareen]

This has to be the very best explanation on significant figures.

[@worldoftanksindiawotblitz1646]

watching from India. 🙏 nice stuff sir... 👍

[@MrWizardjr9]

my chemistry teacher told us that on some problems we shouldn't use sig figs or else we will get a really inaccurate answer and when i asked her how will we know she said you just will. and sure enough on a test there was one such problem and of course i didnt know and used sig figs getting the answer wrong and i still dont quite understand. so you use imprecise measurements and get an imprecise answer that just looks precise so you need to make the imprecise answer less precise just to make it so that it doesnt look precise?

[@mamtapuri6197]

we don't mean to show it imprecise.... but it doesn't make sense to write the whole answer (with all decimals) because it is uncertain, meaning thereby inaccurate...So we show that the answer is 1.9 that is it lies between 1.86 to 1.95 ...... we are uncertain at 1st decimal place ... so it doesn't make sense to show the further decimals... i hope you get it now

[@kinototen45]

You should do a video of significant figures in combine operations.

[@danielnegussie4894]

By far, this is the best tutorial i have seen . Thank you and keep up the good work. you are a tremendous help.

[@physicsbhakt7571]

Thanks a lot. Sharing one's knowledge never fade up, you have uploaded this 8yrs back and now am getting used of it. Love the way of ur teaching ❤️

[@user-jg6xu1kk1i]

No one taught me this at college. They said just f-ing do it this way. I used to plug my numbers in a formula after each chemistry experiment to calculate the standard deviation with out knowing that is standard deviation 😅

[@homehome6882]

Thank you so much Taylor, I look around alot of video which doesn't solve my question except yours! You are gifted with chemistry and explaining , you are a hero to save my chemistry.

[@coco-ez5tl]

You explained it so simply but clearly. Thank you so much!

[@alimuhammadbaig5054]

Question : Sir, shouldn't you use the word "accurate" instead of "precise"? (as accuracy is the measure of the closeness to the actual value)

[@ninanakagawa8943]

yeah i think the same way

[@bluepedalsrock9271]

When you said the MASS of the rock was 82 grams, I think you meant VOLUME..... Just kidding. I was pretending to be one of those people that feel the need to correct you over absurdities. I'm so thankful for your videos, you're going to be the reason I make it through this semester!

[@tdewitt451]

You definitely made me smile. Thanks for the comment!

[@kingkoy7397]

+Tyler DeWitt hey you look like Jesse McCartney.

[@gerry6144]

Volume is measured in cubic centimeters; mass is measured in grams or kg.

[@ujjwal9285]

You have a true soul of teacher

[@agrid]

I have a question, hehe, I've been thinking, let's say you have a big piece of land, and by some reason you want to put 3 division pieces of 3 meters, you have a ruler that can only meassure one decimal of meter, so you meassure 3.0m. So now you multiply 3.0*3 and you get 9.0m right, same precision you begin with, but now that you see that it will only take 9.0m you say, well, I rather make 4 division of 3 meters, so again you multiply 3.0m *4 and now you end up with 12, but, you can only have 2 significant figures, so your result is actually 12.m not 12.0m, but if you instead of multiplying you make the sum, you end up with 12.0m, so what to do? I mean from your instruments 12.0 is doable and with the same precision as your instruments. Or lets say you have a land of 12.0m and you want to divided in 5 pieces, , now you have a by significant figures, 4.00m but that is way more precise than your instrument, but you have 3 significant figures just as the one you begin with. Or in your very example you end up with 2.0 grams per cc, but that .0 is more precise than your instruments, that .0 you cannot know it, because your instruments cannot meassure a decimal of a gram.

[@mridulboro7467]

You are amazing sir, i have understood significant figures completely, that i was struggling with. Thanks a lot❤

[@ElijahVocals]

I've always been confused by this bc I'll get an answer then have to round up +20,000 or something crazy like that. How is that more precise?

[@alberthsin6118]

Hi Tyler, you are an awesome teacher and thank you for making all these videos! I only have one question about one of the words you used in this video. Why did you use the word precise instead of accurate? Based on the definitions of the two words, isn't it better to use the word "accurate" since the rocket laser scale can measure something closer to the actual value?

[@danielmoor5356]

AGREE!

[@henryhachihung]

Awesome explanation!

[@Slothopia13]

thanks man, you explained it really well

[@SamvitAgarwal]

Hey man, awesome video. So essentially the heart of the problem lies in the fact that in chem/physics we often measure things and it is basically impossible to get a measurement that is 100% correct right?

[@djmax45238]

I hate Sig Figs so much, I don't understand how it would be 2.0, since 2.0*42 gives you 84g instead of 82 if you're solving for g algebraically

awesome tyler is the man!
