WASHINGTON, D.C. - President Barack Obama had to try a couple of doors at the White House before finally gaining access to the Oval Office on Wednesday.

Returning from a five-day trip to Latin America, video shows the president strolling up to french doors at the White House and trying the handle on a locked door. He appeared to be whistling as he made his way down to another set of doors that were open.

White House staff was apparently not informed that the President was coming back to work before his arrival.

I saw this hanging in our break room at work and just had to share because it's so true!

Speech is such a hassle, what with the mouth movements, facial expressions and eye contact.

History is just littered with opportunities where texting would have come in handy.

In 1885, a man named Wilson A. Bentley attached a microscope to his camera and took what the Smithsonian considers the first image of a single snowflake.

About eight years later, Bentley sent some 500 snowflake prints to the institution. In light of the recent snow craziness that has fallen on 49 U.S. states, Smithsonian has dug up some of these early 'flake photos. You can see more on its site.

When I saw these, I just had to post them. When we look at the technology today, as compared to where we were 125 years we are light years in difference. Yet, with what is considered relatively low tech today, Wilson A. Bentley was able to take this beautiful shots, which were revolutionary in his time. It causes me to take a moment to think about and remember where things have come from, and where things are going.
