晶议见闻
一，科技公司正在争相招聘M.B.As
https://headtopics.com/us/tech-companies-that-won-the-pandemic-are-snapping-up-m-b-a-s-19569889
亚马逊和其他在新冠大流行中蓬勃发展的科技公司正在争相招聘MBA毕业生，而一些传统的招聘者则暂时停止了招聘。在大流行期间业务激增的科技公司，例如亚马逊。com Inc.和ZoomVideo Communications Inc. 吸引了更多进入工作岗位的MBA人才，以抵消因Covid-19经济遭受重创而造成的经济下滑。根据行业组织MBACareer Services＆EmployerAlliance对近100所学校的调查，去年秋天，全日制MBA在科技公司职位上升了的57％。调查发现，总的来说，对商学院来说，这是一个乏善可陈的招聘季，有近一半的人报告说，学生的机会总体上减少了。亚马逊公司的一位女发言人说，亚马逊计划今年招募1000多名MBA学生，从事全职工作和实习，而Zoom则表示，作为新的全球新兴人才计划的一部分，该公司打算招聘更多的MBA毕业生。Netflix没有发表评论。(采编/翻译:常家睿)
Tech Companies That Won the Pandemic Are Snapping Up M.B.A.s
M.B.A. grads are being snapped up by Amazon and other techcompanies that have thrived in the pandemic, as some traditional big hirerspull back。Techcompanies whosebusinesses have surged during the pandemic—like Amazon . comInc. and Zoom Video Communications Inc. —are snagging more of the M.B.A. talententering the workforce, helping to offset pullbacks by industries harder hit bythe Covid-19 economy.
Openings for tech positions rose at 57% of full-time Masters ofBusiness Administration programs this past fall, according to a survey ofnearly 100 schools by industry group MBA Career Services & EmployerAlliance. Overall, though, it has been a lackluster recruiting season atbusiness schools, the survey found, as nearly half reported an overall declinein opportunities for students. Amazon plans to recruit more than 1,000 M.B.A.students for full-time jobs and internships this year, a company spokeswomansaid, while Zoom said it intends to hire more M.B.A. graduates as part of anew, global emerging-talent program. Netflix had no comment.

三，在保持社交距离的时代，无聊可能构成公共卫生威胁
https://newsela.com/read/boredom-link-to-social-distancing/id/2001019779/
新冠疫情期间，人们对被迫隔离这么长时间已感到厌倦，觉得无聊，变得越来越烦躁不安。这不是一件好事，因为无聊会让人们想做一些不应该做的事情，如违反规定，不想保持社交距离等。据统计，疫情期间发生的违反规定的事情，其中25%是由于无聊，并导致更多的事情发生。解决无聊问题的一种方法是做备选计划。如果以前习惯的做法现在不被允许，就考虑换另一种方式去做自己想做的事情。（采编：王雨乐翻译：刘凡）
Boredom may pose a public health threat in the social distancing era
During this pandemic, people are growing tired of being separatedfor so long. People are getting anxious at home, as well as bored. This isn'tgood, because boredom leads to people wanting to do other things. This mayinclude breaking social distancing rules. 25 percent of rule-breaking duringthe pandemic is due to boredom, which leads to more cases. A way to help solvethis boredom is using if-then plans. If something they used to do isn'tpossible, think of another way to do it.
四，加速度
https://www.sciencenewsforstudents.org/article/scientists-say-acceleration
加速度是一个术语，基本上表示速度随时间变化的速度。速度基本上是指物体沿特定方向移动的速度。加速度与速度和方向都相关，因为速度也是如此。例如，可以加速或向左转的任何东西都是加速，尽管它不仅限于这些动作。减速的物体也正在加速，但是以不同的方式。该加速度为负，也称为减速度。减速适用于速度降低。它也可以应用于方向更改，例如向前和向后移动。某些物体可能具有很高的速度，例如喷气机在空中飞行，只是略微加速或减速。这基本上意味着飞机的加速度较低且速度较高。加速度有时也用于计算力。计算力的公式为F（力）= m（质量）a（加速度）。(采编/翻译: 张乐甜)
Acceleration
Acceleration is aterm which basically means the pace at which velocity changes over time.Velocity basically means the speed that something is moving in a specificdirection. Acceleration relates to both speed and direction becausevelocity does too. For example, anything that can speed up, or turn left,are acceleration, though it is not limited to only those actions. Objects thatare slowing down are also accelerating, but in a different way. This accelerationis negative, also known as deceleration. Deceleration applies to the reductionin speed. It can also be applied to a change in direction, like moving backwardand forward. Something may have a very high velocity, such as a jet goingthrough the air, and just slightly speed up or slow down. That basically meansthat the plane has a low acceleration and a high velocity. Acceleration is alsosometimes used for calculating force. The formula in which to calculate forceis F(force)= m(mass)a(acceleration).

七，高校资源-参加大学入学考试
https://myfuture.com/college/taking-college-entrance-exams
您申请的大学和您在学校的排名将决定您所需要参加的标准化考试。以下是大学最常用来评估学生的标准化考试列表：
PSAT （初步学业能力测试）
PSAT是高中二年级或三年级学生参加的一项考试。目的是获得准备参加ACT或SAT的考试经历。PSAT是一种很好的考试实践，并且通过它可以使您有资格获得国家优异奖学金，最终可以帮助您节省大学费用。由于PSAT只是一项实践考试，因此您在PSAT上获得的分数不会影响您的成绩单。实际上您的PSAT分数可以帮助您了解自己不太擅长的部分，通过花费更多的学习时间提高成绩，会更有效准备ACT和SAT考试。
具体的PSAT信息请看官方网站。（采编/翻译：方可滢）
COLLEGE RESOURCES
TAKING COLLEGE ENTRANCEEXAMS
Thecollege you are applying to and where you stand in school will determine whichstandardized test you need to take. Below is a list of tests colleges mostcommonly use to assess prospective students:
PSAT (PreliminaryScholastic Aptitude Test)
The PSAT is a test taken by sophomores or juniors in high school looking to gaintest-taking experience in preparation for the ACT and SAT. The PSAT serves asgreat practice and taking it qualifies you for the NationalMerit Scholarship, which couldeventually help you save on college.
Becausethe PSAT is only a practice test, the score you receive on it does not affectyour transcript. In fact, your PSAT score is for your betterment; your scorecan identify areas where you need to apply more study time, which may help youprepare for the ACT and SAT more efficiently.

八，一种利用激光冷却反物质的方法可能能够检验现代物理学的基础
最近，物理学家第一次使用激光将反物质深冻结了。在一个新的实验中，紫外线激光停止了抗氢原子的热量引起的抖动，将抗原子冷却到刚好高于绝对零值的温度。这种减慢反物质（与正常物质有相反电荷的物质）的技术可能能够帮助科学家建立第一个反物质分子。研究人员报告说，用激光驯服不守规矩的反物质可能会帮助物理学家更加精确地测量反原子的性质。将反原子与正常原子进行比较可以测试宇宙一些基本的对称性。激光可以通过一系列光子来抑制原子的运动，从而冷却原子。但是，反物质非常难制造，因此很难测试它被激光冷却后的执行。为了制造反氢原子，研究人员在日内瓦附近的CERN粒子物理实验室将反质子与正电子（电子的反粒子）混合。在数小时内，一个特定频率的紫外线的激光束使抗氢原子的旋转速度从每秒90米降到了每秒10米。（采编/翻译：贺英博）
Newly made laser-cooled antimatter could test foundations ofmodern physics
For the first time, physicists have used lasers to deep-freezeantimatter. In a new experiment, an ultraviolet laser quelled the thermaljitters of antihydrogen atoms, chilling the antiatoms to just above absolutezero. This technique for slowing down antimatter — the oppositely chargedcounterpart to normal matter — could help scientists build the first antimattermolecules. Taming unruly antimatter with laser light may also allow physiciststo measure the properties of antiatoms much more precisely, researchers report.Comparing antiatoms with normal atoms could test some fundamental symmetries ofthe universe. Lasers can cool atoms by dampening the atoms’ motion with abarrage of light particles, or photons. However, it’s been hard to laser-coolantimatter because it’s extremely difficult to create. To craft antihydrogenatoms, researchers mixed antiprotons with positrons, the antiparticles ofelectrons, at the CERN particle physics lab near Geneva. Over several hours, alaser beam tuned to a specific frequency of UV light slowed the antihydrogenatoms from whizzing around at up to 90 meters per second to about 10 meters persecond.
九，猫薄荷：驱虫剂？
https://www.sciencenews.org/article/how-catnip-plant-repels-insects-mosquitoes-chemical-receptor
猫薄荷对猫有奇怪的作用，但是新的研究表明它可以用作驱蚊剂。猫薄荷的活性成分荆芥（Nepeta cataria）通过触发刺激疼痛或瘙痒等感觉的化学受体来驱除昆虫。该受体称为TRPA1，在包括人类在内的动物中都很常见，并且对环境刺激物（例如冷，热，芥末和催泪瓦斯）有反应。当刺激物与TRPA1接触时，该反应会使人咳嗽或使昆虫逃跑。研究人员将蚊子和果蝇暴露于猫薄荷中，并注意到果蝇在用猫薄荷或其活性成分处理过的一侧产卵的可能性较小，而蚊子则不太可能从用猫薄荷或其活性成分覆盖的人手臂上吸血。这可以帮助开发更有效的驱虫剂，进而帮助发展中国家抵抗蚊子携带的疾病。(采编/翻译：张乐嘉)
Catnip: An Insect Repellent?
Catnip does oddthings to cats, but new research shows that it could be used as an insectrepellent. The active component of catnip, Nepeta cataria, repels insectsby triggering a chemical receptor that spurs sensations such as pain oritch. The receptor, called TRPA1, is common in animals, including humans,and responds to environmental irritants such as cold, heat, wasabi, and teargas. When irritants encounter TRPA1, the reaction can make people cough or makeinsects flee. Researchers exposed mosquitos and fruit flies to catnip andnoticed that fruit flies were less likely to lay eggs on the side treated withcatnip or its active ingredient and mosquitos were less likely to take bloodfrom a human hand covered in catnip or its active ingredient. This couldaid in the development of more potent insect repellents and in turn help developingcountries fight diseases that mosquitoes carry.
