The days when a cellphone was used for nothing beyond calling and texting are gone．Today，we turn smart phones into magical machines with apps that transform them into musical instruments or business machines or video players．But it turns out that we are only searching the surface．Who knew that smart phones would make pretty good satellites? 1.

Sometimes，you just can’t help it．Maybe you’re watching a sad movie，or thinking about the friend who moved away．Next thing you know，your eyes are watering，and you have tears running down your cheeks．Why do people cry when they are emotional? What are tears? Scientists are working hard to find the answers to these questions．
Ad Vingerhoets is a professor of psychology at Tilburg University，in the Netherlands．He is one of the few scientists in the world who have studied crying．According to Vingerhoets，there are three types of tears．Basal tears are the first type．They lubricate(润滑)the eyes and act as a protective barrier between the eye and the rest of the World．Next are reflex tears．They wash your eyes clean when something gets in them．Finally，there are emotional tears. “These are released in response to emotional states，”explains Vingerhoets．“Especially when we feel helpless．”
Scientists believe that crying has something to do with how humans developed and learned to depend on each other．“Humans are very complex social creatures，”says Lauren Bylsma，a professor at the University of Pittsburgh，in Pennsylvania．“It seems that tears serve to arouse help and support from others，’’She says．“Another reason we weep is that humans have the longest developmental period of almost any animal．It takes a long time to grow up．”
Vingerhoets agrees．“I think that the reason why humans shed tears(流眼泪)has something to do with our childhood，”he says．“That’s the time when we are stir dependent on adults for love and protection and care．The major advantage of emotional tears is that you can target them at a specific person．”Vingerhoets says this ability to target someone could have come in hand in prehistoric times，when humans were living among dangerous animals．Crying could attract predators(捕食者)．Tears were a safer way to get attention．In this case，it is better to use a silent signal to ask for help，”he says．
Vingerhoets and Bylsma do frequent studies to better understand why humans cry．According to Byhma，there is still much more to discover．“It’s surprising，”she says，“how much we still don’t know．”

This Monday，the nation will start to celebrate Presidents’ Day，just seven days before George Washington’s birthday．Everyone agrees that day is a holiday，but is it just to celebrate George Washington’s Birthday? What about Abraham Lincoln? Some government offices call it Presidents’ Day．Others say the holiday is officially Washington’s Birthday．Confused yet?
George Washington was elected the country’s first President on April 30，1789．Soon after，Americans began publicly celebrating his birthday．Presidential historians say the actual date of George Washington’s birth is February 11，1732．But a change in the calendar system 20 years later shifted all dates，making Washington’s birthday February 22，which is now well accepted．In 1879．Congress made Washington’s birthday an official federal holiday．It was the first federal holiday to celebrate an individual’s birthday．In 1968，Congress passed the Monday Holidays Act，which moved the holiday to the third Monday in February．The new law did not change the holiday’s name．It was still called Washington’s Birthday，even though some lawmakers wanted to call it Presidents’ Day to include Abraham Lincoln，whose actual birthday is February 12．
Many people argue that the holiday should celebrate all past Presidents．They feel Lincoln should be honored for his role in preserving the nation during the Civil War and helping to free slaves．Others feel the holiday should only honor Washington．the country’s first President．They say shifting the focus away from Washington would mean future generations of kids would not know about the Father of Our Country．
Laws have been introduced in Congress over the years to require use of the term “George Washington’s Birthday．”but none of those laws have been passed．Meanwhile，many state governments and school districts now use the term “Presidents’ Day．”Many stoles also use it to promote holiday sales．
