The Language of Mathematics (10): Finding Prime Factors

[EmbraceTheUniverse]

My college prof recommended you and i am sooooooooooo glad she did becase you are awesome!!!!!! im scared of math but you made easy and enjoyable for me to learn. thank you soooo much... God bless you:)

[chychochycho]

You're very welcome, glad to have helped... and thank your prof on my behalf for the recommendation :)

Peace.

[Aniloz0220]

thank you...

[chychochycho]

you're welcome.

[eduardosayas]

youre the greatest mathmatics teacher Ever

[rjravaz]

You are the man, your videos never disappoint, awesome video!

[chychochycho]

Thanks. I do try to please :)

[spiritfulness]

If you're looking for a revolutionary new way to visualize the distribution of prime numbers (and especially the twin primes), check out (google) the Croft Spiral Sieve.

Can you explain

FIBONACCIO SERIES / GOLDEN RATIO

in a SIMPLE WAY?

NOT ONLY IDIOT MATH!

(I have heard that in America autours got paid by the number of pages they write.

DO IT SIMPLE (&QUICK), PLEASE!)

[chychochycho]

Oh, I love the golden ratio and all the cool things it relates to in real life, unfortunately though, I won't be able to do a serious piece on it until I do a section on ratios, one on sequences and series, and one on percentages. That being said, I'll see if I can slip in at least one video after the factoring section (Series IIIb) is done, in the next few months that is.

Cool request :)

i dont get it how do u get 224, should it be separate numbers and u just make the 4=2X2

[chychochycho]

That's because we we're breaking down just 4... the number we were breaking down was 448... and 448 = 2 x 224

[bitchslapper12]

Thank you for these Prime number videos, I'll watch more of your wonderful videos! You just earned a heart close fan!

[chychochycho]

Cool :)

im in highschool, i dont know i was really good at math untill 6th grade,than till now im really bad and im allways hanging from failling...i dont get it is it lack of motivation or what,i just dont find the point of mixing up all these numbers and letters and trying to find something more difficult and such, where do you use all this stuff in life? ;( i cant imagine one proffession instead of mathematic's teacher thats using them,whats the point, its so confusing ;( ....

[chychochycho]

Most likely the reason that you started doing bad is because a major connecting concept didn't connect. If you reconnect that thought, things might start to improve.

As for when and where you use math... the short answer is everywhere. What you're asking is the most common question that I have been asked over the years. I will try and deal with it soon. I'm not sure if I will get to it this summer, but it is on the books. Keep an eye out and I'll try and put together at least one video.

[vikmit1]

@chychochycho Great,thanks for the tips, il sub to ya :)

[skinsfan0084]

Chyco, My friend, You don't even know how much this helked me. I'm taking PreAlgebra in college and I hate it. I was stuck and had no idea what the heck I was doing, after watching this video, it gave me an understanding on what to do. I thank you and look forward to watching a bunch more as I move on....

[chychochycho]

Awesome! I hope at least some of the other videos have the same effect. I've had a few "I get it moments" with math and with life in general myself, and love the feeling. Makes me feel really good to have participated in one with you, and thank you for letting me know :)

[052spartan]

Dude, I wish my teachers would have pointed this out when I was in school, thanks for the awesome videos

[chychochycho]

you're welcome :)

[mmille10]

Really liked this! I learned about prime numbers in school years ago, but they were never presented like this. I do recall using prime numbers in some sort of encoding/decoding scheme on a computer as a computer science exercise when I was in high school, though.

[danousd]

Has anyone ever noticed a connection between prime numbers and quantum or string theory?

[chychochycho]

good question. I went to a math forum to ask. Here is what one comment said.

* "I am certainly no expert, but from what I understand, the connection lies in the spacing of zeros of the Riemann zeta function and the spacing of eigenvalues of random (Hermitian) matrices.

[chychochycho]

* "Here is the relevant link. To quote "...the pair correlation between pairs of zeros of the Riemann zeta function (normalized to have unit average spacing) is ... , as Freeman Dyson pointed out to him, is the same as the pair correlation function of random Hermitian matrices.""

unfortunately, i can not explain what this means ... i would have to study it further.

[danousd]

Thank you! However, that stuff is over my head for now. It's fascinating when mathematical discoveries precede observations in nature (e.g. the golden ratio).

[TheVishalvindoorty]

good

[aligrafix1985]

Thanks.. I found that great for me to understand prime numbers..

Do you mind if I download this video ?

Another Question Where I can found the exercises you mentioned in the video

Really thanks.. =)

[chychochycho]

glad it helped, and no worries about downloading it. I've actually provided a table of contents for all the videos to make it easy for anyone that does want to download them. Check out the second link in the description to the right.

as for the exercises, go to the table of contents (first link on the right) and try the exercises in sections 5 and 6.

good luck, and if you find any mistakes please let me know. I tend to make silly mistakes when i do the problems.

[aligrafix1985]

It helped me and thanks to guide me to the problems...

at least I can say thank you for free tutorials

Thanks !

[smackdownbb4]

thank you ,thank you thank you,,,,,

[chychochycho]

you're welcome, you're welcome you're welcome :)

[richyo1000]

I've been interested in the famous 'problem 8' for a long time now so i was searching for some help!Although this is not what i'm looking for i watched it anyway because it's really well taught!Thanks for taking the time to do this stuff man, I can tell you're helping lot's of people out!five stars from me!

^_^

[chychochycho]

Awesome :)

[julesperez7]

thanks a lot! im a fifth grader and this really helped me with homework!

[chychochycho]

you're welcome :)

[OakasuProductions]

Wow you have got to be like the best teacher on youtube. That just brought my grade up to an A for sure.

[chychochycho]

an A would be awesome :-)

[H0D0NKAIN]

I love prime numbers. I wish that they would of explained prime numbers more when I was in high school. Ever since I learned about primes and why they are needed it has made math more fun and more understandable. Very cool video. :)

[unklwlly]

Thank you!

[chychochycho]

My pleasure :)

[unklwlly]

Thank you!
