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.

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 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.

Silence is a rare commodity these days. There's traffic, construction, air-conditioning, your neighbor's lawnmower ... and all this unwanted sound can have a surprising impact on your health, says noise researcher Mathias Basner. Discover the science behind how noise affects your health and sleep -- and how you can get more of the benefits of the sound of silence.

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.

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."

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.

Wind can be one of the most critical and complicated loads on civil structures. The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure. When you push the envelope, you have to be vigilant because things that didn’t matter before start to become important (e.g. wind loads on lighter structures). Unanticipated challenges are a cost of innovation and that’s something that we can all keep in mind.
