INTRODUCTION:
http://www.chycho.com/?q=Introduction_Instructions

During the last few years the education systems in Canada and the United States have been eroding. Students have been crammed into larger class sizes while the quality of teaching has deteriorated, in large part due to a lack of funding from local and federal governments.

John Ralston Saul, one of Canada's most celebrated authors and essayist, has warned us that "Canada's democracy... is eroding with every dime deducted from education budgets."

I have stated previously that I believe "as a collective we must understand that democracy can only exist in a society with an educated populace, and the right for self-governance can only be obtained through knowledge." I also believe that as long as the Internet remains Neutral, we, as a global community, can make a difference. We can fill the gap left behind by our governments and be proactive in educating our children

Sharing our communal experiences and knowledge is the essence of the Internet and chycho.com is proud to be a part of this movement. The information contained and conveyed through this medium is what will shape our future, and this site was created to represent a unique personal perspective and to contribute in bringing about positive changes.

As a result I have decide to produce instructional math videos to help those that want to improve their abilities in communicating in the language of mathematics. The videos are available on Chycho TV Located in the top right corner of http://www.chycho.com. Even though these videos are geared towards high school students, they will also help those in elementary school and those that are struggling with certain college and university courses.

The format of the videos is as follows: Lessons are in large part self contained and most have exercises which should be completed before proceeding to the next lesson. To help people understand a specific topic I have included answers to the exercises.

During the next few weeks and months, possibly years, I hope to be able to provide a vast library of resources for those that wish to finally understand the language of mathematics.

If there are certain areas that you are having problems with or wish me to discuss further then please send me a message or post a comment at my website. Even though I can not guarantee that I will be able to properly represent a topic I will try my best to produce a lesson if there is strong enough demand for a specific topic.

I hope these videos will help people learn how to communicate in the language that we have chosen to understand the world around us in a scientific manner, in the language of mathematics.

Best

[COOTBALLIN]

when you talk about the size of a black hole, what are you referring to? the mass or the volume? cause thats kind of important. a black hole's only conceivable volume is the event horizon, or the black hole's 'effective distance' if you will, because the actual mass in a black hole has an infinite density. basically, if you put enough mass in a small enough space, all that mass's mutual gravity will eventually cause it all to collapse inward creating a black hole.

[chychochycho]

Actually I'm referring to both the mass and the volume, they are related. From what I understand, you are correct to say that the only volume that we can measure is by looking at the event horizon, but that signature is directly related to the volume/mass of the black hole (the collapsed body, the singularity).

As for density, I don't believe that black holes have infinite density (i could be wrong though).

we r 25000 mph motion but don't feel it and bloody sun juts twist on axis and make summer and winter but circle motion never even deffer like ealips or prabolic motion strange if this distance differ i mean sun straitght come close 500mile and go back 1000 mile hhahaha just burn

[wafi0123]

sir the arguemet is not the mass but matter of mass with out gravitational force ok mass but mass cannot be masure with out mass or no mass mean not genarate mass or this secrecy of centric action of law

[COOTBALLIN]

@COOTBALLIN (Einstein lost the argument, they did an experiment that proved it. I don't remember the details though, it was hard to understand right after I read it, and it was a while ago)

[COOTBALLIN]

@chychochycho I could be wrong about the infinite density thing, I still dont get the snag. this problem reminds me of Einstein's with quantum mechanics, the proponents of quantum mechanics argued that physics is only the study of what we can observe, and Einstein argued it is the study of what is "real." I guess if a BH's EH was the size of an EP, since we observe their effects in the same ways, they are the same. if the singularity was that size the EH would be different

vel, black holes would have a lower limit at the planck length

[MatthewMitch23051992]

Black hole have only been measured to reach a certain mass. The theory is that when matter and anti matter forms on the point of no return and the matter escapes, the anitmatter removes mass from the black hole. A certain number of black holes reach a certain size and then stop growing, atleast this has been observed so far.
