Please note, since The Pirate Bay was taken down it’s become harder to provide constant direct links to the torrents. The torrents are still available, I usually have two computer seeding them, so please look for the torrents on other file sharing sites such as KickassTorrents.

Hopefully in time we will be able to create a society where we can share content freely without government or corporate interference, until then, happy seeding.

Direct links to torrents on The Pirate Bay (Please note: The Pirate Bay gets taken down a lot by governments so if the links below don't work please go the "Videos Available for Download" page. It contains the most updated links):
• Series I: Videos #1 to #35 for The Language of Mathematics, produced in 2007.
• Series II: Videos #36 to #58 for The Language of Mathematics, produced in 2008.
• Series IIIa: Videos #61 to #92 for The Language of Mathematics, produced in 2009.
• Series IIIb: Videos #93 to #142 for The Language of Mathematics, produced in 2010-2011.
• Series IVa: Videos #143 to #151 for The Language of Mathematics plus some videos for Math in Real Life, produced in 2011-2013.

### II. Description

At the request of my readers, in 2009 I began to provide torrents for the math videos. The torrents are available through The Pirate Bay and other file sharing networks.

Downloads are series specific and the files organized based on their video number and/or year, i.e, the order in which the videos were produced. See the table of contents for The Language of Mathematics and Math in Real Life to put things into context.

Please note that videos from Series I, II, and IIIa are tagged with chycho.com, and those for Series IIIb and Series IVa are tagged with 420math.com.

### III. Video Update

1. You got hacked? Who was your host?

2. My hosting company was DreamHost.

A play by play of how everything unfolded at: HELP URGENT! My email got changed, not by me and Re: HELP URGENT! My email got changed, not by me.

The quick version of what happened HERE.

3. Really sorry, you are helping people with this, and stupid people come and do this to you .

thank you for helping me in my math chycho

From guatemala

4. You're welcome Byron, and no worries about the site. It's a lesson learned from my part. Taught me to go a little high end with the next sites and to make sure to set up some fail safes - once the math sites go up, I really don't want them to go down :)

5. Hi chycho ~ I can't seem to find these excersizes for the videos. How do access them? We are beginning at the beginning. Thanks ~ Owlpixie

6. Hi bodypiercingbyilka,

Unfortunately all the exercises got zapped when my site was hacked and taken down :(

Getting them back up is on my list but it won't happen for a while yet, sorry.

7. bummer. Thanks for the videos, they are very helpful and informative. Do you recommend another site with excersises that may substitue? I really appreciate your help. You are a very gifted man with incredible teaching skill.

8. Series looks great, Chycho! Really looking forward to going through the Series step by
and hoping for that moment of illumination
when the data set becomes a comprehensive body
of knowledge in my mind available for use at any time!

Thanks for your help and encouragement!

Warmest regards,

Eligah

9. bodypiercingbyilka,

I haven't been following any of the other sites that provide math content so, unfortunately, I can't recommend anyone. That being said, I know Khan Academy provides some awesome videos, a different style than what i do. You could check his site and see if he has any exercises.

10. Thanks Eligah, I'll do my best to make it happen for you. I plan on introducing something new this year which may help. Will let everyone know more about it later :)

Peace,

chycho

I am a doctor now! I find your videos very useful. Good to recollect what I did many years back.

Why do you film your videos at noisy surroundings? They too irritate and are a distraction. I think your lectures would be better at the comfort of your cosy home where you had filmed the introduction.

Good work

Shri

12. Thanks Shri,

Regarding the sound, I've improved it for Series IV so hopefully that helps. Doing these videos was my first time trying anything like this so I really didn't know what I was getting myself into.

As for why do it outside, my best answer is that I like being outside, and since the editing takes me a while to do, if i didn't shoot the videos outside i would never see the sun, feel the wind, or taste the rain.

Thanks again, and welcome to my site.

Peace,

chycho

13. Dearest Chycho:

This is Khalid Butt from Lahore, Pakistan. Only last month I found your Math Videos. You are doing great missionery work. I will go through them and will try to teach my children. Do you have texts of your Videos already done. God bless you and yours - Amen!

Kindest Personal Regards
Khalid Butt

14. Hello Khalid, hope your kids find the videos helpful. Let me know if you need any help... as for text, sorry, no text yet. It'll be quite some time before i reach that point.

Peace,

chycho

Again thank you and God Bless you with your Educational Mission - Amen!

Best Regards
Khalid

16. It's my pleasure Khalid.

As for Series IV, I just started it so there are a lot more videos to come. I don't provide the torrent until a series is finished. That said, I'm pretty sure you can download what I have up to this point from youtube.

Good luck :)

17. Forget my last message, I have the downloaded torrent version and, having looked on youtube, the correction was made in a white popup at the bottom of the video. Agan, thanks for doing these videos, your helping a lot of people learn and enjoy mathematics, all the best Chycho.

Usually I only hear from those who have seen the videos on youtube. It's good to know that the torrents are being well used as well.

All the best,

chycho

18. You rock Chyncho, after coming across your videos, i was so excited and would spend hours listening to your lectures. I love your style, coherence, selection of topics. I start recommending it to every one who struggles at math.
When every one tries to mince money out of their limited potential, you stand out as a human, and I am sure these videos are great help for those who are not able to afford standard education. Your videos are one of the bests i have even seen. God bless you and your family.

1. Thank you, SR. Very much appreciate your kind words. What I'm doing here is sort of a labor of love and it's an amazing feeling to share it.

Thanks again, you made me feel very good on this Wednesday night.

Peace,

chycho
