The Basics of Math—Made Clear
Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic(算数) and to prepare them for Algebra (代数) and beyond.
The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents (指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.
Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing — and completely understandable — field of study.
By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery (神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.

A mother from Colorado who doctors said had died while giving birth to her son, has said it is a Christmas miracle that both she and the boy are alive.
Tracey Hermanstorfer's heart stopped beating and her son Coltyn appeared lifeless after the Caesarean section(剖腹产手术）on Christmas Eve. However a few minutes after he was born, both began breathing again. Dr Stephanie Martin told Good Morning America she could not explain how the pair survived. Mrs. Hermanstorfer and her husband Mike told the American television show that their baby was now healthy and that they were doing “good” following the drama at Colorado Springs Memorial Hospital.
The couple，who already had two children, had to go into the hospital seven weeks earlier than planned. Her husband, 37, said his wife was tired after receiving an epidural (硬膜夕卜麻醉）during the labour (分娩)but after closing her eyes, she "wasn't waking up". She stopped breathing and she is believed to have suffered a heart attack before her heart stopped beating entirely.
Dr Martin said she was called in and that the outlook was grim since in most situations like this，"despite the best efforts of the team"，the mother was often unable to be revived. In that case doctors then tried to focus on delivering the baby but when he was born he was "completely lifeless".
Mr. Hermanstorfer told the Associated Press news agency，" I had everything in the world taken from me, and in an hour and a half I had everything given to me. "
Dr Martin said she did not have a “great explanation" for why Mrs. Hermanstorfer、heartbeat re-turned. "Somewhere between four and five minutes she had been without heart rate and had stopped breathing a minute or two prior to her heart stop-ping," she said. The doctors were then able to bring the baby back to life, and the mother was alive after that.

Some scientists suggest that these contacts with nature are good for your health. In one study, hospital patients with a view of trees had shorter hospital stays and less need for pain medications. Another study indicated that prisoners with a view of the outdoors had fewer doctor visits.
“Why the desire for nature? Maybe we’re programmed to need it, since our ancestors’ survival was so dependent on their connection with nature,” suggests biologist E.O.Wilson.
Want to find out if contact with nature improves your outlook on life? Try a few of these ideas.
Hang out a bird feeder and watch the birds that visit it.
Sit down in the backyard or a nearby park. Close your eyes. What do you hear? Birds singing? The wind in the trees? Crickets(蟋蟀) chirping?
