For the 44th time in the 283 years of the Republic of the United States of America, one President will step down as another takes their place. In the grand tradition of the office, outgoing President Barack Obama gave his farewell speech in Chicago, the city that he called home and gave him his start in politics. Over his nearly hour-long speech, President Obama cited the challenges, successes, failures, and his still-strong belief in the ability of this nation to change for the better.
Even if you live in a part of the country that experiences all four seasons, you've never seen them like this before. Using experiments and chemical reactions, this video depicts flowers blooming, leaves falling, waves crashing, and snow falling in microscopic form.
We spend about a third of our life sleeping, so the mattress you sleep on every night is incredibly important. Make sure you get the right one by trying out a Casper. This USA-made mattress is made up of multiple layers of foam, including one for support and pressure relief, and one to make sure you don't get too hot. It's all wrapped up in a durable woven cover, and shipped right to your door in a box that's easy to maneuver into even the smallest abodes. You get 100 nights to try it out, can return it for free if you're not satisfied, but if you are (and you probably will be), you can upgrade even further by grabbing some of the company's soft Supima cotton sheets and dual-layer pillows.

Coders, managers, illustrators — whatever your job, odds are you've had to deal with a whiteboard before. Now you can carry one with you with the Wipebook Pro. This notebook holds 20 writeable pages that work just like a normal whiteboard, letting you write, erase, and re-write countless times. Brass binding lets it lay flat, cow-friendly faux leather front and rear covers help when it's time to digitize a page, and unlike the board at work, you can take it home without ever having to worry about an overzealous janitor "cleaning" away your valuable notes.

Right now, your inbox is probably crammed with an insane number of marketing emails. That one account you created to access that one piece of information that you only needed that one time was all it took to open the floodgates. Director and comedian James Veitch describes his attempt to unsubscribe from one such email and how he hilariously fought back when they just kept coming.
Graphene is thought to be the strongest material known — in its two-dimensional form. Replicating that 2D strength in three dimensions has been problematic for scientists for decades. But researchers at MIT think they've found a solution. This new 3D-printed material has just 5% of the density of steel with over 10 times the strength, opening doors for applications from airplanes to filtration systems.
