In honor to Black History Month, I want you to look up a famous African American mathematician and what did they do to improve the world of mathematics. You may find that they also influenced the world of science. Describe who they are and when they became famous. Why are they being honored?
Since we just had a Friday the 13th…..many people have superstitions about this number. The facts/theories of why 13 is scary are listed below. All of them can be seen as fact or fiction. Since we have no true written proof to why 13 is scary for some or that bad things will happen (supposedly), these can be theories to consider.
Read the suggested facts below and tell me what you think about them. YOU NEED to comment on two of the statements, voicing your opinion either for or against the statement. THEN, tell me what the number 13 means to you.
REMEMBER YOU NEED TO SEND ME YOUR COMMENT ANSWERING THE QUESTION ABOVE AND YOU NEED TO COMMENT ON ANOTHER PERSON BLOG POST.
The number 13
1. It is believed that the fear for the number 13 stems from primitive man being unable to count past 12. Numbers beyond 12 do now have an individual and independent name but are a combination of the first 12 numbers. With 12 being the end of the line, 13 was moving into unknown territory.
2. In Norse mythology the 13th number led to the death of Baldur, the beloved of the gods. When the 12 gods gathered for a banquet in Valhalla, Loki gatecrashed the party, increasing the number to 13, which led to the death of Baldur. It also happens that in Tarot cards, 13 is called “Death.”
The baker’s dozen
3. The “unlucky 13″ is the reason why the thirteen loaves that bakers once supplied were never called by the number, but described as “a baker’s dozen.” The thirteenth loaf was regarded as a special bribe for the devil not to spoil the sale or the bread.
The lucky number 13
4. But 13 is not unlucky for all. The Mayas worshipped the 13 gods of the upper world. The Aztecs climbed 13 steps to their sacred places. Buddhists paid homage to 13 Buddhas. In Jewish faith, God revealed Himself by 13 attributes of bountiful mercy (Exodus 34: 6-7). The orthodox Jewish prayer book hold the Thirteen Principles of Faith. Jewish boys celebrate their Bar Mitzvah at age 13.
5. The number 13 in Greek is triskaideka and the fear of the number 13 is called triskaidekaphobia.

For the month of October, I want you to think about this question….research it and post what you think is the correct answer. After you have discovered the correct answer, you then need to tell me why we use it in math. What is its purpose. Don’t forget your response to me needs to be 5 sentences long. Then you respond to a friends BLOG and that can be shorter. Due October 31.
Question:
What mathematical symbol did math whiz Ferdinand von Lindemann determine to be a transcendental number in 1882?
Hello Students….
This is a BLOG and a BLOG is a way for us to share information in an educated setting. Here we will discuss current events, math techniques, etc and you will have a chance to post your own comments about what you think it means to you. There is no right or wrong answer- what I am looking for in order to get full credit is that you participated and you stayed on topic. Also that you gave a reasonable answer to the opposed question or comment. If you write “I agree,” that is not a reasonable answer. You must have full sentences, had it spell checked, had it grammar check and it must be on topic. You need to make one post per month and have it completed by the due date. You are also to comment on at least one students comment. ALL COMMENTS ARE READ BY THE TEACHER AND OTHER STUDENTS FROM OTHER PERIODS. YOU MUST BE RESPECTFUL, NO BULLYING, NO TEASING, NO CURSING, AND NO SLANG OF ANY KIND. IF YOU DO ANY OF THESE VIOLATIONS OR OTHERS NOT MENTIONED- YOU WILL RECEIVE A CONSEQUENCE DEPENDING ON THE VIOLATION.
For your first Blog—- DUE SEPTEMBER 30—-
What is the hardest part about math for you? Is it the memorizing of facts, formulas, and techniques? Is it the work, the classwork/homework, the steps to do a problem? Or could it be that dealing with numbers is confusing? If math is one of favorite subjects, explain how you like it more than other subjects. Your comments need to be at least 5 sentences (full sentences) long.
