    Why Bridges Move...

    Why Bridges Move...

    This video explains why ridges move, and other musings on thermal movement of large civil works. Most people have a certain intuition about thermal expansion, but you may not have considered how engineers design to accommodate it on large civil structures. The video gives a quick overview on this important consideration that engineers must account for when designing infrastructure like pipelines, bridges, and even sidewalks.

    Why Concrete Needs Reinforcement

    Why Concrete Needs Reinforcement

    This video shows more destructive testing to answer your questions about concrete. Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement.

    Why It's So Hard to Make Healthy Decisions

    Why do we make poor decisions that we know are bad for our health? In this frank, funny talk, behavioral economist and health policy expert David Asch explains why our behavior is often irrational -- in highly predictable ways -- and shows how we can harness this irrationality to make better decisions and improve our health care system overall.

    Why Tunnels Don't Collapse

    Why Tunnels Don't Collapse

    This video shows how simple reinforcement is used to prevent collapse of rock tunnels. Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

    Why We Get Mad -- And Why It's Healthy

    Why We Get Mad -- And Why It's Healthy

    Anger researcher Ryan Martin draws from a career studying what makes people mad to explain some of the cognitive processes behind anger -- and why a healthy dose of it can actually be useful. "Your anger exists in you ... because it offered your ancestors, both human and nonhuman, an evolutionary advantage," he says. "[It's] a powerful and healthy force in your life."

    Why evaluate legal information?

    In this video, a year 3 LLB student who is preparing a term paper with a substantial research component regularly consults his supervisor. In a recent meeting, the supervisor queries why two pieces of information were cited in his draft. One piece of information is from a local real estate agent’s website summarizing the legal provision for the Hong Kong deed of mutual covenant agreements. Another piece of information is a court case covered in a Hong Kong land law blog.
