I think most of the math professor, they just now how to apply the formulas, but they do not know the logic behind. Without logic, no one will be motivated to learn. Keep doing this great job, you are opening my eyes every time I watch one of your videos. I am a big fan of you!

Greetings in Jesus name our Lord and saviour, are you interested in hearing about the Gospel of Jesus Christ who is our lord and savior? Originally man lived in pure happiness with God in Paradise but we sinned by disobeying God by eating fruit from the forbidden tree, because of this we were thrown out of Paradise and onto this earth, as we stubbornly found pleasure in eating from the forbidden tree although there were better trees to eat from in the Garden of Eden. God loves us so much that he made a way for us to enter back into paradise by sending his only son Jesus to die for our sins so that he can give us eternal life and save us from death and eternal punishment in Hell. Here is a pray that you and others can say to receive Jesus Christ as your Lord and saviour. Father in Heaven I receive your son Jesus as my Lord and saviour, I confess my sins and I ask you to forgive me for all my sins, wash and cleanse me and everything pertaining to me with the blood of your son Jesus and wash away all my spots, blemishes and wrinkles with the blood of your son Jesus. Father God in Heaven fill me with your Holy spirit every moment of my life and give me infinite oil for my spiritual lamps. I forgive and release all those who have done me wrong and I ask you to bless them and write my name permanently in the lambs book of life in Heaven in Jesus name I pray amen. Here is another pray to break curses and bind demons in our lives. Father God in Heaven I break and loose myself and my family from all curses going all the way back to Adam and Eve and I bind every demon and demonic influence in my life and in my family life permanently in Jesus name. I command all demons in my life and in my family life and those around me to leave and never return in Jesus name. Father God send your legions of Angels to fight for me until the end and send your ministering angels to keep ministering to me and always guide and protect me from all evil, I command Satan to get thee behind me and all of Gods creatures in Jesus name I pray amen. Pray always and study the KJV Bible to know more about Jesus and God's plan for our lives. Jesus bless you. Please pass on this message.

I believe your video is a great starting point. And I find graphs are things of beauty!
