This is also known as "free energy", and one way of thinking about entropy is as the lack of free energy. The sun provides us with useful, low entropy, energy in the form of photons of visible light, which are then absorbed and converted into plants, sugar, complex molecules, etc, before being radiated back into space as heat, which has much higher entropy.

So, electric current works like a river... kinda... Instead of flowing based on elevation, electric current works a little differently. But it s a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric current, voltaic cells, and how we get electric charge. -- Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios -- Want to find Crash Course elsewhere on the internet?

Designer Ali Budd shares an open living and dining room with fashion-forward finishes and statement pieces that wow. Get her expert tips on how to mix textures, fabrics and unexpected pieces to create a livable space that’s beautiful and classic with an edge. For Ali, the key to a standout room is layering elements that don’t always match and pushing the boundaries of design to add interest and unique style. In the living room, she paired two small tables together to act as a coffee table, and mixed woven fabrics with faux leather and velvet-look polyester for a layered look that’s comfortable and easy to clean. A custom black walnut Parsons-style table displays overlapping photographs that the homeowner, a photographer, took himself. In the dining room, mid-century modern chairs dress up the dining table, while a statement light fixture steals the show.

Why aren t you travelling the world? What can you do today to get started? What s the problem? Money? Time? What s the excuse? I got some friends together and we created this video. Some of you may not like it, it might make you feel uncomfortable, that s ok. It might make you angry, and that we don t understand... that s ok too. For many of us we were once at that point too. We just want you to look at your excuses, and really ask yourself, are these real? I know that some of you have legitimate reasons, and some need to think twice. We hope that this will help a few people off the fence. Changing your attitude is the real way to travel the world. Many of life s obstacles can be overcome. Breaking goals down into small steps is how big dreams come true. A dollar a day in a bank account does more than make 30 dollars a month, it plants a seed that changes how you think. The idea behind this video is to give you some Motivation and Inspiration to make a change in your life. To join us. There are hundreds of thousands of people making the sacrifices they need to, to be able to see the world. Why aren t you one of them? We filmed this in Leipzig, Germany.

Crucially, we don’t just sulk with anyone. We reserve our sulks for people we believe should understand us but happen on a given occasion not to. We could explain what is wrong to them of course, but if we did so, it would mean that they had failed to understand us intuitively and therefore, that they were not worthy of love.

How do art and morality intersect? Today we look at an ethically questionable work of art and discuss R. G. Collingwood’s view that art is best when it helps us live better lives. We’ll go over Aristotle’s concept of catharsis and how it can resolve the problem of tragedy. We are also exploring the paradox of fiction and the debate between autonomism and moralism. -- Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Crash Course Philosophy is sponsored by Squarespace. http://www.squarespace.com/crashcourse -- Want to find Crash Course elsewhere on the internet?

Ask This Old House general contractor Tom Silva and host Kevin O’Connor use stair treads to create a simple bookshelf in Build It. SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse This simple bookcase was designed to be built using a circular saw, a cordless drill/driver, a block plane, and a chisel. Because the shelf is made out of veneered stair treads, it’s designed to be paint grade, not stain grade. All of the materials for this project, including pine stair treads, 1x4 pine, 1/4” plywood, 3 1/8” trim head screws, and 5d box nails can be purchased at home centers. Cost: $100 Time: 3-4 hours Skill level: Easy Tools: Drill/driver Circular saw Clamps Hand plane Straight edge Chisel Steps: Measure out desired lengths; in this case, Tom measured out 38 inches and made a cut point using a straight edge. Cut stair treads for shelving to length using a circular saw. Leave two stair treads at 48-inch length for use at the sides of the bookshelf. Rip each shelf down by 1 ½-inches using a straight edge and a circular saw. Rip both sides down by ¾ of an inch using the same method. To inset the plywood into the sides and hide the end grain of the plywood, make rabbet cuts by setting ¼” cutting depth on the circular saw and a straight edge to mark the width of the cut. After the first pass, move the straight edge out just a little to remove some of the waste on a second pass with the circular saw. Remove the remainder of the waste using a utility knife. The top will also need a rabbet cut, however this one will not run the whole length of the board. This stop rabbet will start and stop within 1” of the end of the top piece. Cut the rabbet like on the sides, but starting your saw 1” in and finishing your cut 1” from the end. Clean up the stop rabbet and square it off using a chisel. To lay out the measurements for the bookshelf, place each side piece side-by-side. Lay a 1x4 toe kick at the base and hold the first piece of shelving flush against it. Mark where the top of the shelf will lie. Measure 16 inches between the top of the first shelf to the bottom of the second shelf. Mark the top and bottom, then repeat it on the next shelf up. (Note: you can make the distance between shelves any dimension you wish at this stage based on what you plan to store). Pre-drill holes on each side piece between the marks you made for the shelf locations using a drill/driver. Use 3 1/8” trim head screws to fasten each shelf to the sides using a drill/driver. Do the same for the toe kick. To match the sides of the top shelving piece to the stair tread nosing, mark the center of the nosing and the distance to the back of the nosing. Use those markings to hand plane, rounding the edge as you go, until nosing matches that of the stair tread. Fasten the top shelving piece onto the bookshelf using trim head screws and a drill/driver. Nail the plywood portion onto the back using 5d box nails and a hammer. Sand, prime, fill nail holes, and paint the finished bookshelf (Note: using the materials shown, this shelf is only paint grade and cannot be stained). Build It: This Old House general contractor Tom Silva, This Old House host Kevin O’Connor, and special guests including Jimmy DiResta, take you through step-by-step DIY projects in this popular video series.
