“The End of Astronauts”, Robotic Space Exploration and Our Future on Earth and Beyond with Professor Martin Rees

Human space exploration is challenging as well as fascinating. However, the excitement of space flight for astronauts comes at a high cost and is riddled with danger. As our robot explorers become more capable, governments and corporations must consider whether the ambition to send astronauts to the Moon and Mars is worth the cost and risk. In this episode of Bridging the Gaps, I speak with professor Martin Rees who is one of the authors of “The End of Astronauts: Why Robots Are the Future of Exploration”. The book makes the provocative argument for space exploration without astronauts and suggests that beyond low-Earth orbit, space exploration should proceed without humans. In this discussion, we also touch upon some intriguing points the professor Martin Rees discusses in one of his previous books “On the Future: Prospects for Humanity”.

Martin Rees is an emeritus professor of Cosmology and Astrophysics at the University of Cambridge. He is the UK’s Astronomer Royal, a fellow of Trinity College and a co-founder of the Centre for the Study of Existential Risks at Cambridge University (CSER).

We start by discussing our fascination with human space journeys and exploration. We discuss the title of the book “The End of Astronauts” which seems a bit strong. We then discuss the progress in developing better and smarter robots for robotic space exploration. We discuss the progress made by private space companies in reducing the cost for space missions. Professor Rees emphasise the point that space is hostile and difficult environment and we should avoid using terms as space tourism, instead you should call it space adventures.

We then discuss the book “On the Future: Prospects for Humanity” and touch upon topics such as colonisations of Mars, post human era; genetic engineering and our future on earth and beyond.

Quantum Computers: Building and Harnessing the Power of Quantum Machines with Professor Andrea Morello

Quantum computers store data and perform computations by utilizing properties of quantum physics. Quantum computations are performed by these machines by utilizing quantum state features such as superposition and entanglement. Traditional computers store data in binary “bits,” which can be either 0s or 1s. A quantum bit, or qubit, is the fundamental memory unit in a quantum computer. Quantum states such as the spin of an electron or the direction of a photon, are used to create qubits. This could be very useful for specific problems where quantum computers could considerably outperform even the most powerful supercomputers. In this episode of Bridging the Gaps I speak with professor Andrea Morello and we discuss fascinating science & engineering of conceptualizing and building quantum computers. Professor Andrea Morello helps us to unpack and tackle questions such as what a quantum computer is and how we build a quantum computer.

Andrea Morello is the professor of Quantum Engineering in the School of Electrical Engineering and Telecommunications at the University of New South Wales Sydney, Australia.

I begin our conversation by asking professor Morello what a quantum computer is, and how it differs from classical and conventional computers. The no-cloning theorem’s implications in the field of quantum computers are next discussed. The no-cloning theorem states that it is impossible to create an independent and identical copy of an unknown quantum state. Professor Morello’s team uses single-spin in silicon to construct quantum computers, and we go over their approach in depth. The true value of quantum computers can only be realised if we develop creative algorithms that make effective use of quantum computers’ exponentially huge information space and processing capability. We discuss this in detail. We also touch upon the concept of quantum chaos and discuss research in this area. This has been a fascinating discussion.

“Nano Comes to Life”: DNA NanoTech, Medicine and the Future of Biology with Professor Sonia Contera

Nano Comes to Like on Bridging the Gaps

Nanotechnology allows scientists to better understand, interact with, and manipulate biology by creating and manufacturing artificial structures and even machines at the nanoscale out of DNA, proteins, and other biological molecules. From nanoscale machines that can target individual cancer cells and deliver drugs more effectively to nanoantibiotics that can fight resistant bacteria, to the engineering of tissues and organs for research, drug discovery, and transplantation, nanotechnology is revolutionizing medicine in ways that will have profound effects on our health and longevity.

In this episode of Bridging the Gaps I speak with Professor Sonia Contera and we discuss fascinating research that she presents in her book “Nano Comes to Life: How Nanotechnology Is Transforming Medicine and the Future of Biology”. The book introduces readers to nanotechnologies, which are fast advancing and allowing us to influence the basic building components of life. Sonia Contera provides an insider’s view of this new frontier, explaining how nanotechnology permits a new sort of transdisciplinary science that has the potential to give us power over our own biology, health, and lifestyles. Sonia Contera is professor of biological physics in the Department of Physics at the University of Oxford. Her work lies at the interface of physics, biology, and nanotechnology, with a particular focus on the role of mechanics in biology.

We start by discussing the scale at which nanotechnologies function. The evolution of instruments and technology that allow us to perceive and interact with matter on such a microscopic scale is then discussed. The convergence of numerous sciences that are at the heart of such breakthroughs are then discussed, allowing us to build nano-scale structures from the ground up. We then discuss the fascinating research that enables researchers to design proteins on a computer simulator, figure out what kind of GENOME will make such protein from that simulated protein, create that GENOME, and then put it in a real cell to create that protein in reality. We also touch upon the cutting edge research in DNA Nanotechnology and other enabling technologies such as Artificial Intelligence, and the future of biology and medicine. This has been a fascinating discussion.
