I'm Aaron! I spent 6 years learning Spanish in school, and graduated barely able to speak at all. That was before I learned HOW to learn languages. Now I speak English, Spanish, French, Esperanto, some Thai, and I'm actively learning Greek. Stick around and we'll discuss what you should be doing to finally learn that language that's been on your mind. A new language will enhance your life!

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

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

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.

Water hammer can work in both directions, and I only discussed one of those in the previous video (https://youtu.be/xoLmVFAFjn4). This episode revisits that demonstration to show how water hammer can form a vacuum pressure in a pipe. Momentum carrying fluid away from a valve wants to keep going even after the valve is closed. This generates a negative pressure than can cause major damage!

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.

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.

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?

This video gives a quick overview of how we build underwater structures. Oceans, rivers, and lakes are often beautiful, but they’re not necessarily convenient places to build things. Yet, many types of the infrastructure we depend on every day, including wharves, bridges, and dams, are founded below the water. How do they do it? On this episode, we're talking about different types of underwater construction, including cofferdams, diversions, caissons, and drilled shafts. Whether the construction site is on the bottom of a lake or river, or simply located in the floodplain and only at risk during extreme weather, engineers and construction contractors put a significant amount of thought and consideration into the feasibility and costs of managing this water.

Traffic management in dense urban areas is an extremely complex problem with a host of conflicting goals and challenges. One of the most fundamental of those challenges happens at an intersection, where multiple streams of traffic - including vehicles, bikes and pedestrians - need to safely, and with any luck, efficiently, cross each others’ paths. However we accommodate it now or in future, traffic will continue to be one of the biggest challenges in our urban areas and traffic signals will continue to be one of its solutions.

We normally build a dam to hold water back and store it for use in water supply, irrigation, hydropower, or flood control. But sometimes we have to let some water go. Whether we need it downstream or the impounded water behind the dam is simply too full to store any more, nearly every dam needs a spillway to safely discharge water. The spillway is a critical part of any dam and often the most complex component. So how does it work?

In many ways, the grid is a one-size-fits-all system - a gigantic machine to which we all connect spinning in perfect synchrony across, in some cases, an entire continent. On the other hand, our electricity needs, including when we need it, how much we need, and how reliably it should be delivered vary widely. Substations play a critical role in controlling and protecting the power grid.

Discussing some of the fascinating engineering that goes into overhead electric power transmission lines. In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity over long distances has become more and more important. Stringing power lines across the landscape to connect cities to power plants may seem as simple as connecting an extension cord to an outlet, but the engineering behind these electric superhighways is more complicated and fascinating than you might think.

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.

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.

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.

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.

Sinkholes form through both natural and human-made processes. Most of us think about erosion on the surface of the earth, but erosion can occur in the subsurface as well. In fact, scientist and engineers have a very creative name for just such a process: internal erosion. If just the right factors come together in the subsurface, some very interesting things can occur, including sinkholes.

This video explores the protective systems that keep the power grid from self destructing. We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things go wrong. When your power goes out, it’s easy to be frustrated at the inconvenience, but consider also being thankful that it probably means things are working as designed to protect the grid as a whole and ensure a speedy and cost-effective repair to the fault.

This video gives a quick description and demo of this ingenious pump. A hydraulic ram is a clever device invented over 200 years ago that can pump water uphill with no other external source of power except for the water flowing into it and there is a way to take advantage of this normally inauspicious effect for a beneficial use. The ram pump is an ingenious way to take advantage of the properties of fluids. We all need water for a variety of reasons, so being able to move it where we need it without any fancy equipment or external sources of power is a pretty nice tool to have in your toolbox.

This video gives a brief overview of this ingenious method of compressing air using only the power of water. The way a trompe harnesses the power of water to generate compressed air with no moving parts is fascinating and its use is seeing a small revival in modern days. A trompe can be useful in off-grid aquaponics and hydroponic systems that need aeration of the water. And, in fact, the inspiration for this video came from the late Bruce Leavitt, a mining engineer who pioneered the use of small trompes for aeration and treatment of mining water in remote locations without access to electricity.
