Sohmers表示:“我曾经先后三次申请加入麻省理工学院研究室。我第一次申请的时候是14岁,那时我的父母并不太支持我。但是后来他们发现我在高中里学习并不快乐。于是他们开始慢慢理解了我的想法。现在他们对我的工作非常支持。”在加入麻省理工学院研究室之后,Sohmers终于找到了属于自己的天地。如今已经17岁的Sohmers表示,自己并不后悔放弃学业,进行创业。他表示:“即使我无法改变世界,也会收获一些其他的东西。人们在讨论上学和创业的时候,总是顾虑太多。但是企业是在研究者眼中,你的学历高低并不重要,重要的是你的能力。”

新美国基金会(New America Foundation)高级研究员李?德鲁特曼(Lee Drutman)在一份给Vox的分析文章中指出,在阿肯色州、北卡罗莱纳州和田纳西州,移民人口是1990年的三倍以上。围绕这些变化产生的焦虑或许可以解释共和党为什么在这个阶段更关注限制移民问题,还有这些州的白人投票者们何以压倒性地支持特朗普。

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
