Tour interior designer and blogger Jacquelyn Clark of Lark & Linen‘s rental apartment! See how she created a bright and welcoming home despite space constraints and get her budget-friendly decorating tips, DIY inspiration and more. Jacquelyn used rugs to divide the open-concept rental apartment into zones, and created focal points to define the separate areas. A gallery wall with photos of her travels and drawings centers the dining room, while a simple mirror over the fireplace makes a subtle statement in the living room. To save money on furniture, Jacquelyn refurbished family heirlooms with a fresh coat of paint and new hardware. The blogger lives with her boyfriend, so contrasted the apartment’s soft palette with masculine elements, like a DIY bookshelf made of pipes. A wall above the office space painted in stripes is the main attraction in the apartment.

But that’s not the full story — radiation also applies to rainbows and a doctor examining an X-ray. So what is it, really, and how much should we worry about its effects? Matt Anticole describes the different types of radiation. Lesson by Matt Anticole, animation by Tinmouse Animation Studio.

Joe and Sarah Knight of blackLAB architects inc. open up their cool, contemporary family home. See how they converted a 1940s house into a sleek and modern space thats cozy, inviting and kid-friendly. The original layout consisted of small, dark rooms, so an open floor plan was the first step to modernize the interior. Adding a courtyard with floor-to-ceiling windows to the back of the home helped bring in natural light. They also warmed up the black and white palette with walnut flooring and millwork, as well pops of playful color for the kids. These accents create a space that has all the elements of modern design – an open floor plan, a monochromatic palette – yet is beautifully livable.

Humans have evolved: are we still doing so? Very slowly perhaps, but what’s really changing is how we are adapting to the natural environment. And here, the nerds are winning.

Why do people buy the stuff they buy? In classical economics, most models assume that consumers behave rationally. As you ve probably noticed in your real life, in case after case, people don t actually make rational decisions. There can be emotional or social reasons for all this irrationality, and behavioral economics tries to address this. We ll talk about risk, nudge theory, prices and perception, and the ultimatum game. So, let s get irrational, in a logical way, of course. Crash Course is on Patreon!
