For the first time in history: The new face of the 20$ bill will be a Woman!

  
A woman’s face is finally going to grace the front of our paper currency and it’s going to be abolitionist icon Harriet Tubman, who is best known for her work with the Underground Railroad that helped former slaves escape captivity. Politico reports that Tubman’s face will replace Andrew Jackson’s on the $20 bill, while Alexander Hamilton will keep his place on the $10 bill.

U.S. treasury secretary Jack Lew last year said that he planned to replace Hamilton’s face with a woman’s on the $10 bill, although that decision generated a backlash from many people who said that we should keep our first-ever treasury secretary on the front of our currency. Former U.S. president Andrew Jackson, meanwhile, doesn’t have nearly as much of a cult following and is thus a prime target to be replaced by Harriet Tubman.

Politico’s sources say that while Hamilton will remain the face of the $10 bill, “leaders of the movement to give women the right to vote on the back of the bill.” Additionally, it seems “there will also be changes to the $5 bill to depict civil rights era leaders,” although Abraham Lincoln will remain on the front of the bill.

Of course, it also helps that Hamilton now has a smash-hit broadway musical named after him as well, so even hipsters who know nothing about history can be happy that his face is staying on the $10 bill. And Tubman is the perfect choice as the first American woman to go on the $20 bill, as she’s an icon who worked tirelessly to both end slavery and promote women’s suffrage.

It’s been 40 years since the world’s first mobile phone call !

On April 3rd 1973, Martin Cooper made the first mobile call on the nine-inch (and 28-ounce) Motorola DynaTAC. Dialing up a rival at AT&T, he apparently said that he was ringing “to see if my call sounds good at your end.”

While briefcase-size models had come before it, it’s Motorola’s truly mobile phone that became the go-to power accessory for the likes of Gordon Gekko, Zack Morris and, er, American Psycho‘s Patrick Bateman.

Since its heyday, however, the AMPS analog networks that the phone used to run on have now largely disappeared, replaced by digital ones that have added better call clarity, not to mention data connectivity at ever-improving speeds. We’ve come a long way.
