Brain Game: Old Money

Washington is on the $1, Jefferson on the $2, Lincoln the $5, Hamilton the $10, Jackson the $20, Grant the $50, and Franklin the $100 billYou don't see $2 bills like this very often, but they're legal tender and are still printed every few years. The reason I've shown you this particular currency note - and its portrait of Thomas Jefferson - is to help facilitate today's Brain Game. (Mouse over the image if you need a quick refresher of who appears on which denomination.) Good luck!

Take the men whose portraits currently appear on the

$1, $2, $5, $10, $20, $50, and $100 bills,

and place them in order from oldest (born first) to youngest.

Here is the SOLUTION.


Statesman Ben Franklin is the oldest of the bunch, born way back in 1706. The whole list:

1706 - Benjamin Franklin ($100)
1732 - George Washington ($1)
1743 - Thomas Jefferson ($2)
1755 - Alexander Hamilton ($10)
1767 - Andrew Jackson ($20)
1809 - Abraham Lincoln ($5)
1822 - Ulysses S. Grant ($50)

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.
