Technically Speaking | a science and engineering discussion

In a ideal world, everything that is no longer useful is given a new life. Laura, Cara and Antonia discuss this as one idea behind a concept known as the circular economy. In this two part episode, we introduce some ways in which we see waste being repurposed and talk about the first two stages in the life of a product: manufacture (and resource gathering), and; product use by the consumer. Can something be infinitely recycled? What is recyling anyway? How is our behaviour as consumers influenced by design, marketing, and  science?

Why should you believe a scientist when they talk about climate or sustainability and how should they convey their expertise in a way that makes sense to you? Laura, Aneeqa and Rwayda discuss some aspects of science and engineering that you can't see with your own eyes and therefore can be difficult to describe.

Recorded over zoom with an audience from The University Of Manchester's Dalton Nuclear Institute supplying comments via the chat function, the team also come up with some ideas for how science communication could be improved. They don't have all of the answers, but its an interesting conversation.

Transport has shaped society, and society has shaped how we travel and connect with each other. In this chicken-and-egg story Laura, Rwayda, Amina, Cara and Antonia share stories about what transport means to them and look at how our transport options have evolved since ancient times. They look at some history and decision making, how atoms feature in materials science and engineering, and consider the future of space travel.

This special episode was recorded with an audience from the Engineering Development Trust's Insight into University summer programme.

Movies often use bridges to represent something, and they're often destroyed in the process. Antonia, Laura, Rwayda and Alex discuss the engineering behind some of the most iconic bridges as well as some of their favourite movie scenes featuring bridges: Spiderman, Indiana Jones and Shrek.

We explain how engineers consider the dynamic forces acting on a bridge and we mention this video of the Tacoma Narrows Bridge, an example of what happens when the forces aren't fully taken into account.

How are building materials chosen and what makes some materials fire-resistant? Aneeqa, Laura and Rwayda discuss some aspects of fire engineering and share a few personal stories where they have used science to their advantange. True to form, they also throw in some pop-culture references; hello Vin Diesel!

Have you ever thought about where we get the lithium from for Li-ion batteries? Laura, Antonia, Aneeqa and Amina discuss trends in car ownership, where we get lithium from, how difficult it is to recycle these batteries, what the ethical implications of lithium mining are, and how this fits in with UK government plans to tackle the climate emergency.

The team share stories about their individual career paths, talk about the women that inspire us, and what engineering means to us.

Do you ever think about how your own background or the stories you read in the media influence your own view of the world? Amina, Aneeqa, Cara and Antonia discuss what we mean by scientific findings and talk about some ways where science has been used to provide a biased narrative. Using examples from veganism, nutrition, climate change and the car emissions scandal, they also discuss whether there can be benefit to focussing the story in this way or whether being too focused can be detrimental.

Sparked by an article that Ghalia saw in the news, she is joined by Laura, Antonia and Aneeqa to discuss just how big our carbon footprint is, how it compares to other things and how difficult is can be to calculate it.

Did you know that the change in habits brought about by the pandemic had a huge impact on our water supply? Or how about how the water industry helped track the pandemic? Amina, Ghalia, Laura and Rwayda talk about how their use of water changed because of the pandemic and the wider effect of sudden, national changes in water use on the industry, while also thinking about the link to other utilities.
