Have you ever come across times when you get particularly nervous, say during a presentation, you find it extra hard to speak smoothly? Most of us may stop at times when we talk, so how do we differentiate between Normal Dysfluency and Stuttering? Are kids struggling with words due to language ability or are they stuttering? Will they naturally outgrow stuttering? How do speech therapists help adults and children who stutter?
大家有否試過在某些時間特別緊張，例如在發佈會中，你覺得難以流暢地說話? 其實每一個人說話時也會有停頓的時候，到底我們如何分辨「口吃」和正常的不流暢呢？ 孩子到底是口吃還是因語言能力較弱而在找字呢？是否長大後自然會沒有口吃的問題？ 言語治療師可以如何幫助受口吃困擾的小孩和成人呢？

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.

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.

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."

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.

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.

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.

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.

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.

Tech that can decode your brain activity and reveal what you're thinking and feeling is on the horizon, says legal scholar and ethicist Nita Farahany. What will it mean for our already violated sense of privacy? In a cautionary talk, Farahany warns of a society where people are arrested for merely thinking about committing a crime (like in "Minority Report") and private interests sell our brain data -- and makes the case for a right to cognitive liberty that protects our freedom of thought and self-determination.

Sometimes conventional reinforcement isn't enough. The basics of prestressed concrete. Prestressing reinforcement doesn't necessarily make concrete stronger. But, it does increase the serviceability of concrete members by reducing the amount of deflection under load. This video explains the two most common types of prestressed concrete: pre-tensioned and post-tensioned. Prestressed concrete is used in all kinds of structures from bridges to buildings to silos and tanks. It’s a great way to minimize cracking and take fuller advantage of the incredible strength of reinforced concrete.

What's the difference between concrete and cement? Concrete is the most important construction material on earth and foundation of our modern society. At first glance it seems rudimentary, but there is a tremendous amount of complexity involved in every part of designing and placing concrete. This video is meant to be a bare-bones introduction to the topic, with a cool demonstration of concrete strength using a hydraulic press.
