Nicolaus Copernicus was a polymath (scientist) born in Prussia (now Poland) who placed the earth at the center of the universe. YES. It's his name we should recognize when we become self-centered.

Old Warsaw - It was a cold winter weekend in Warsaw - just like home.

One of the few buildings that withstood the German destruction was at the divide between the Russians and Germans.

Center square of Old Warsaw downtown. All of this was rebuilt since WWII. The Royal Castle of Warsaw was rebuilt entirely by the citizens and tourists of Warsaw and was not completed until 1984. Think about that for a while.

Warsaw fought the Nazis with everything they had, something the Russians found controversial and downplayed. It was due to this resistance that Germany destroyed 90% of Warsaw. Visiting this monument and Old Warsaw is truly moving.

It's common in this part of Europe to keep Christmas decorations out until February.

My goal is to take selfies at every IBM location I visit. Not sure the count so far but is high double-digits.

This is one of the most unique Hilton locations I've visited - sitting over the highway overlooking Stockholm's frozen harbor.

We took a ferry to the museum.

Stockholm is loaded with museums. Their cultural museum is beautiful from outside on this frigid day. Yes, it was about 10° in Stockholm.

This is me in front of the Vasa. You can't imagine how big this ship is. Sunk on its maiden voyage 500 yards from where it sits, it was restored in 1983. Quite a fascinating thing to witness.

Intricate details on its tail gives you an idea how much effort went into this massive ship. Just one problem. It toppled and sank in light winds on its maiden voyage.

High atop the tallest building in Stockholm, you get an idea how pretty the city is in the winter night light.

Of course I had meatballs in Sweden!

Selfie at IBM Stockholm Innovation Studio where we presented to a dozen or so partners.

Amsterdam Centraal Station is quite an interesting building.

Not only beautiful, Catholic churches are rare in this part of the world.

Bicycles are an integral part of Amsterdam. There are more bicycles than people in the city.

Three cities in about 10 days and three IBM locations
