The vast majority of our grid-scale storage of electricity uses this clever method. Electricity faces a fundamental problem that comes with pretty much any product that’s provided on-demand: our ability to generate large amounts of it doesn’t match up that closely with when we need it. The storage of electricity for later use, especially on a large scale, is quite challenging. That’s not to say that we don’t store energy at grid scale though, and there’s one type of storage that makes up the vast majority of our current capacity.

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.

Being diagnosed with autism is often seen as a tragedy. But for Jac den Houting, it was the best thing that's ever happened to them. As an autistic person, concepts like the Neurodiversity paradigm, the Social Model of Disability, and the Double Empathy Problem were life-changing for Jac. In this talk, Jac combines these ideas with their own personal story to explain why we need to rethink the way that we understand autism. Jac den Houting is a research psychologist and Autistic activist in pursuit of social justice. Jac currently holds the role of Postdoctoral Research Associate at Macquarie University in Sydney, working alongside Professor Liz Pellicano. In 2015, Jac was awarded an Autism CRC scholarship to complete their PhD through the Autism Centre of Excellence at Griffith University in Brisbane. Prior to this, they gained almost 10 years’ experience as a psychologist in the criminal justice system, with the Queensland Police Service and Queensland Corrective Services. Jac was identified as Autistic at the age of 25, and is proudly neurodivergent and queer. After participating in the inaugural Future Leaders Program at the 2013 Asia Pacific Autism Conference, Jac quickly became established as a strong advocate for the Autistic community. Jac is a current member of the Autistic Self Advocacy Network of Australia and New Zealand (ASAN-AuNZ)’s Executive Committee, the Autism CRC’s Data Access Committee, Aspect’s LGBTQIA+ Autism Advisory Committee, and the Aspect Advisory Council. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Earthquakes have always been a terrifying phenomenon, and they’ve become more deadly as our cities have grown — with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be prevented? Vicki V. May explains the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.

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.

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.

Chances are you'll need to find a scholarly journal article for a research paper or project in the near future. But, wait, what is a "scholarly journal article?" How is it different from a popular source like a newspaper or magazine article? Let's reduce the confusion on scholarly journal articles. Scholarly journals enable scholars -- experts in a particular academic field -- to communicate their research with other experts in that field through publishing articles and to stay current by reading about other scholars' work. Consequently, scholarly journals create a community of scholars who are all participating in a kind of "conversation" in that academic field. Rather than a face-to-face conversation, this is a formal conversation, which takes place over months and years through written documents. The most important part of this long term written conversation - what makes it a “scholarly” conversation, as opposed to popular - is what's called the “peer review process.” The peer review process works like this: in order for a scholar to get published in a scholarly journal, his or her expert peers must read their work and critique it. These “peer reviewers” make sure that the scholar has cited the appropriate experts in the discipline, made valid and well-supported arguments, and has written the article on a topic that is appropriate for that particular journal. This rigorous evaluation process ensures that scholarly work meets a higher standard than popular publications. So, why is this important for you? First, the information in a scholarly text has been rigorously evaluated, so it is more reliable and credible than information in popular sources. Second, reading scholarly journal articles for your papers or projects can give you insight into the ways of thinking of experts in that field. Finally, every scholarly text has extensive bibliographies that introduce you to important texts in the field, which can help you extend your research in that area. When you read the articles and books the scholar cited in her article, you are taking part in the scholarly conversation.

A weir is a small dam built across a river to control the upstream water level. Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies. Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level. Over time, the term weir has taken on a more general definition in engineering to apply to any hydraulic control structure that allows water to flow over its top, often called its crest. In fact, the spillways of many large dams use weirs as control structures. So how do they work?

In many of the world’s tallest skyscrapers, there’s a secret device protecting the building and the people inside from strong motion due to wind and earthquakes. Did you know you can tune a skyscraper just like a guitar? In this video, we’re comparing theory to the real world for tuned mass dampers. Luckily this tech is simple enough that we can model it right in the garage. As silly as this little experiment looks, it’s actually not that far off from what engineers do in the real world (maybe without the googly eyes). The design phase for just about every major building includes some physical scale model tests. This video shows that the tuned mass damper is a great example of elegance in engineering.

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.

In general, and compared to other common building materials, metals have excellent mechanical properties. They are hard, tough, strong, and durable. As someone who occasionally works the wood, even I can admit that metals are a superior material in many regards. So you can see why it would be advantageous to have a way to connect them together, especially if you can do it in such a way that joint isn’t the weakest part of your assembly. That’s the goal of welding, and luckily, this is not something reserved for industrial factories and machine shops. From my own experiences so far, welding is something you might be able to do yourself as a hobby. And stay tuned till the end for some tips for getting started.

In this lesson, we'll be looking at the cell cycle. This is the lifespan of a eukaryotic somatic cell. A somatic cell is any cell in the body of an organism, except for sex cells such as sperm and egg cells. The cell cycle describes the sequence of cell growth and division. A cell spends most of its life a state called interphase. Interphase has three phases, the G1, S, and G2 phases. Interphase is followed by cell division, which has one phase, the M phase. Together these four phases make up the entire cell cycle. G1 of interphase is sometimes called growth 1 or gap phase 1. In G1, a cell is busy growing and carrying out whatever function it's supposed to do. Note that some cells, such as muscle and nerve cells, exit the cell cycle after G1 because they do not divide again. A cell enters the S phase after it grows to the point where it's no longer able to function well and needs to divide. The S stands for synthesis, which means to make, because a copy of DNA is being made during this phase. Once DNA replication is complete, the cell enters the shortest and the last part of interphase called G2, also known as growth 2 or gap phase 2. Right now, it's enough to know that further preparations for cell division take place in the G2 phase. Now that interphase is over, the cell is ready for cell division, which happens in the M phase. The M phase has two events. The main one is mitosis, which is division of the cell's nucleus, followed by cytokinesis, a division of the cytoplasm. So, at the end of M phase, you have two daughter cells identical to each other and identical to the original cell. Let's review. The cell cycle describes the life cycle of an individual cell. It has four phases, three in interphase and one for cell division. Most cell growth and function happen during G1. The cell enters the S phase when it needs to divide. In this phase the cell replicates its DNA. Replication just means the cell makes a copy of its DNA. In G2, the cell undergoes further preparations for cell division. Finally, we have cell division in the M phase. The M phase consists of mitosis, which is nuclear division, and cytokinesis, or division of the cytoplasm. We'll explore the details of mitosis and cytokinesis separately

Almost everyone agrees that flooding is bad. Most years it’s the number one natural disaster in the US by dollars of damage. So being able to characterize flood risks is a crucial job of civil engineers. Engineering hydrology has equal parts statistics and understanding how society treats risks. Water is incredibly important to us, and it shapes almost every facet of our lives, but it’s almost never in the right place at the right time. Sometimes there’s not enough, like in a drought or just an arid region, but we also need to be prepared for the times when there’s too much water, a flood. Rainfall and streamflow have tremendous variability and it’s the engineer’s job to characterize that so that we can make rational and intelligent decisions about how we develop the world around us.
