Luca Pacioli is the one on the left. (Nobody knows who the guy on the right is.)
The story of the birth of accounting begins with numbers. In the 1400s, much of Europe was still using Roman numerals, and finding it really hard to easily add or subtract. (Try adding MCVI to XCIV.)
But fortunately, Arabic numerals (1, 2, 3, 4, etc.) started catching on, and with those numbers, merchants in Venice developed a revolutionary system we now call "double-entry" bookkeeping. This is how it works:
Jose Garces is among the most talented and innovative chefs in America. He opened his first restaurant, Amada, in 2005, and since then his Garces Group has opened 14 other restaurants across the country.
In 2009, he won the James Beard Award for Best Chef in the Mid-Atlantic region, and he's also a Food Network Iron Chef, rubbing elbows with the likes of Bobby Flay, Cat Cora and Michael Symon.
This is TALK OF THE NATION. I'm Lynn Neary. Mitt Romney proved he could go head-to-head with President Obama in the first of three presidential debates last night in Denver. Romney's strong performance gave Republicans renewed hope for his chance at the White House.
Dominican-American novelist Junot Diaz was awarded a MacArthur "genius grant" and the no-strings-attached $500,000 prize that comes with it. The Pulitzer prize-winning author of The Brief And Wondrous Life Of Oscar Wao talks about the grant, his writing process and how the award may affect his work.

In case anyone was wondering, this week's presidential debate demonstrated why incumbent presidents and others leading in the polls used to refuse to debate their challengers.
After John F. Kennedy used the first TV debates to boost his campaign against incumbent Vice President Richard Nixon in 1960, there simply were no debates until 1976. Running again with a big lead in 1968 and 1972, Nixon declined to debate and won both times. Lyndon B. Johnson also demurred in 1964 without damage en route to a landslide.
In the aftermath of death, many adults struggle with how to talk to kids while dealing with their own grief. Often, the instinct is to protect children from pain and loss. That can sometimes leave kids out of the family grieving process, which can leave them feeling lonely and misunderstood.
The Oxford English Dictionary needs your help. Do you know where words like disco, baked Alaska or email come from? For years the widely regarded authority in the English language has asked the public for help tracking down the history of words and phrases. Yet as our lexicon evolves, the mission grows even tougher. A new initiative called OED Appeals hopes to solve that problem by using that same crowdsourcing approach online.
