朱元璋刚打到了和州，孙德崖就打了过来。郭子兴带了几万兵来打孙德崖的几万兵，但这么多人哪里能在和州这么小的地方打仗呀？孙德崖有道理，跟朱元璋说他自己会走开。但郭子兴很蠢，把孙德崖抓了起来。孙德崖的兵把朱元璋抓了起来，然后郭子兴就蒙了。最后，把朱元璋和孙德崖放回去后，朱元璋开始攻打南京。但这些事令郭子兴很生气，因为他让手下的敌人跑了。郭子兴得了心病，死了。到了南京，朱元璋两次打都失败了，但这是好事，因为朱元璋的上级都死了，他终于可以自己领导整个军队了。他十天就攻下了南京。有一个叫张士诚的人，他是贩私盐的。他觉得实在忍不住了，开始了起义，自称王了。元朝的军队冲上来，十万大军，打了三月，最后张士诚赢了。这事谁都不会想到，张士诚这么小的军队怎么防的住元朝的大军？因为张士诚想：“不打也要死，所以干嘛不打？”但之后，张士诚有钱了，就变了，不想起义了。

朱重八跟造反的人连起来。他一进军，就被汤和看出来是优秀的人了。不久，他就变成郭子兴的生边军。他又娶了个老婆。但是，郭子兴一晚上被几个别的起义军领导的军打了。朱重八救了他，然后这让郭子兴觉得朱重八太厉害了，想干掉他，所以把他关进监狱里，不给他食物。他的妻子给他送吃的，然后郭子兴把朱重八放走了因为他不想杀朱重八。朱重八后来攒了很多兵，开始自己的起义军。后来，郭子兴被赶出他自己的起义军的时候，朱重八因为‘以前如果没有郭子兴就不会有现在’把他的起义军让给了郭子兴。郭子兴了解了，朱重八是对的，他不应该对他不好。

Recently, there has been growing concern at the Center for Disease Control over using your cellphone too much. A 2010 study said that there was no problem with using your cellphone, but that was 2010, and cellphone usage has increased by a lot in the past few years. When the CDC published new guidelines 18 months ago regarding the radiation risk from cellphones, it used unusually bold language on the topic for the American health agency: “We recommend caution in cellphone use.” The agency’s website previously had said that any risks “likely are comparable to other lifestyle choices we make every day.” Within weeks, though, the C.D.C. reversed course. It no longer recommended caution, and deleted a passage specifically addressing potential risks for children. There seems to be a lot of debate, as many scientists have reached different conclusions based on the same evidence. Radiation released by nuclear bombs is obviously harmful. Known as ionizing radiation, it is powerful enou

There has recently been a new innovation in technology, called the OrCam MyMe. Like Google Glass, the OrCam MyMe will speak to you through a Bluetooth earpiece. However, rather than hanging suspended above your eye, the MyMe camera is a pendant designed to clip unobtrusively on your shirt or perhaps your belt. The camera is designed to not have the privacy problems that the Google Glass faced, because it does not record user data, it just analyzes it. For example, one of the most interesting potential applications will be MyMe’s ability to generate a “word cloud” from a conversation without actually recording the conversation itself. The idea is that you would be able to later gather insights to your interactions with people in a less invasive and more useful manner. There are many other applications for this technology, and I think it might be paired with VR to create virtual worlds that are personalized for you to explore.

Meditation reduces stress and anxiety, makes people kinder, and gives people a more overall sense of well-being. The author of the article I read, Michael Hsu, apparently has practiced wu ming qigong for 15 years. For years, he was a fanatic and practiced many times each day. Yet now, with a family of three children, he cannot afford so much time to meditate. So he looked into ways to meditate less, so he wouldn't have to practice so much, but meditate better. That's how he found the Muse, a $300 meditation device that helps people meditate. It works by sensing your brain waves. The more unfocused you are, the louder the sound it makes gets, and if you reach ultimate focus, you hear birds chirping. Apparently this is a very effective tool, because he became more aware of what was going on around him, and also he really enjoyed using it, as it has an effective motivation system. After a while, he felt that he really wanted to use it every day. I think the Muse sounds interest
