Einstein’s Outrageous Legacy: Cosmic Illusions and Gravitational Waves

It has been a century since Einstein changed our way of looking at gravity. Einstein showed us that Newton's idea that any two things in the Universe pull each other with a gravitational force wasn't the whole story: gravitational attraction is due to the distortion of space and time. This view works, but can have many outrageous consequences, two of which will be described in this talk: light can bend around stars and galaxies, causing mirages and illusions on a cosmic scale, and as things move in space, it vibrates like a drum. These 'ripples' of space-time, predicted by Einstein almost a century ago are the most characteristic departure from Newtonian's gravity. Such 'gravitational' waves are distortions of space-time that carry a large amount of energy and yet produce only infinitesimally small effects as they pass through space at the speed of light.

The Basics of Microscopy Through the History of Optics and Microscopy

It is interesting to learn about microscopy through its history. This history is fascinating, starting with the ancient Greeks who asked questions like “What is light?”. In this lecture, I will take you through the basics of light-matter interactions like reflection and refraction. I will then tell you how lenses work and how to combine them to create optical systems like microscopes. We will also look at some advanced concepts, like the wave nature of light and how this concept is the centerpiece of microscopy. I will try to relate all these concepts to historical facts and make these ideas as intuitive and visual as possible.

Soft and Squishy Materials and How to Think About Them

The materials we see around us can be hard (a metal spoon) or soft (a well-made idli or your earlobe). Many materials fall in-between extremes of hardness and softness. Other types of materials (honey, water) flow. Some materials flow easily while others flow very, very slowly. I'd like to describe the ideas behind our understanding of how the materials we see around us behave, drawing your attention to simple everyday observations. These ideas are particularly useful in connecting biology to both physics and chemistry.

A Gentle Introduction to the Bayesian Approach for Analysing Our Ecology and Ecosystems

Scientific questions, data, models and methods need to be integrated rather than seeing data analysis and statistics as an afterthought of the scientific process. There are two schools of statistics: frequentist and bayesian. Unlike the frequentist approach, the Bayesian approach allows for updating existing information and data with new data collected in a study through Bayes theorem.

The existing information and available evidence can be summarized in the form of probability distributions with varying degrees of uncertainty built in. This is where some subjectivity may creep in. This is essentially like a quantitative statement of an a priori hypothesis. Furthermore these approaches enable us to avoid nonsensical and impossible "null" hypotheses and instead start with a plausible one that incorporates available evidence and knowledge explicitly in the form of statistical and scientific priors. We use simple graphics and examples from ecology and the environmental sciences and everyday life in India to illustrate the strengths and challenges of the bayesian and quasi-bayesian approaches in understanding and interpreting complex phenomena.

Modern Microscopy Techniques

There are a lot of biological structures, which we can study using conventional widefield or confocal microscopy. We can resolve individual cells, and even larger organelles inside of cells, such as the nucleus, or the endoplasmic reticulum.

On the sample size front, you can have the smallest sample (a single bacterium ~1um) up to the zebrafish of almost 1 cm length. There are many biological structures of interest, which are smaller than these objects. In order to access these structures, scientists need to turn to techniques such as electron microscopy. Super Resolution Imaging techniques like SIM, STED, and Localization Microscopy are allowing scientists to answer questions about these smaller structures, such as mitochondria, viruses, synaptic vesicles and even the locations of individual proteins. In contrast to electron microscopy, super-resolution fluorescence microscopy maintains the benefit of being able to target multiple structures of interest with fluorescent tags and even study the structures in living specimens.

The Origin of Life

How life first emerged on the early Earth is one of the great mysteries of science. I will talk about how we think the chemical building blocks of biology were formed and then spontaneously assembled into the first very simple cells. I’ll show some examples of how such primitive cells might grow and divide, and I’ll discuss current ideas about the early Earth environments that may have nurtured the first life on our young planet.

Next-generation Targeting has Organelle-level Precision

Organelles are small membrane-bound compartments inside cell. Just like organs of the body perform specific functions for the body, organelles of cells perform specific functions for the cell. Their activity and chemical composition therefore, reflect the cell’s metabolic state. Metabolism is altered in disease or upon aging and this is reflected at the level of organelles inside our cells. Nature can already deliver cargo from outside the cell to reach specific organelles precisely in the cell. Cases in point are invading pathogens that invade us, or nutrients that the cell needs. My lab has made DNA nanodevices and we have shown that we can deliver these nanodevices to precise organelles, just like Nature does.

DNA can be made chemically, and we can fold it to form nanometer-sized assemblies, commonly referred to as DNA nanodevices. Our first discovery in 2011 revealed that DNA nanodevices could reach organelles called lysosomes in live worms, where it functioned like a pH-meter. Until this innovation, it was not at all obvious whether such DNA nanodevices could function inside a living cell without being interfered with, or interfering with, the cell’s own DNA. Today we show that we can now deliver therapeutics with organelle-level precision in whole animals.

What is Infinity?

Counting is one of the first human activities. We will discuss what it means, and then discuss the notion of infinity. Infinite sets have some surprises in store. Understanding them is necessary for doing a large part of mathematics.

The Exciting New World of AI Research

We begin by sharing a personal perspective of witnessing and benefiting from the growth of computer science from a niche field to one that is impacting every aspect of the world, enabled by an exponential rate of increase in computing power. In particular, we describe the recent advances in the area of artificial intelligence, and the high-level ideas underlying the progressively narrower domains of machine learning, deep learning, and foundation models, which have emerged over time as dominant paradigms for artificial intelligence. We describe the tremendous progress of these models on problems ranging from understanding, prediction, and creativity on one hand, and open technical challenges like safety, fairness, and transparency on the other hand.

These challenges are further amplified as we seek to advance Inclusive AI to tackle problems for over a billion human beings in the context of India and the Global South. We present our work on multilingual models to democratize information access in a diverse set of Indian languages, on healthcare in environments where we lack data in digital form, to begin with, and on analysis of satellite imagery to help transform agriculture and improve the lives of farmers. Through these examples, we hope to convey the excitement of pursuing a research career at this time when there are fascinating open problems to tackle and an unprecedented opportunity to make a difference to the world.

Encounters: Between Wonder and the Strange

I will share the works that map the complexities of ecology, time and space, through the twin frames of wonder and the strange. At the core of this is a recognition of the entanglement of relationships in the natural world, but also of their deep strangeness, their weirdness, and the places that are created by their grafting and fusion.

Chemistry in the Building of Matter: Atoms to Molecules to Materials

Chemistry has been a central science in the understanding of molecules from Atoms. Further, materials are built out of molecules and chemical science helps us in the understanding and design of molecules and devices for functional materials which are helpful for renewable energy, climate change, healthcare and environmental materials. Quantum principles with multiscale simulations, synthetic designs and analytic tools have helped in the design of functional molecules and materials.

Mapping and Finding Our Place in the Universe

In this talk, we will time travel and journey back to the early Universe. We will trace the origin and evolution of the Universe, its visible and invisible constituents: galaxies, dark matter and black holes. Our map of the Universe has transformed fundamentally - just a hundred years ago, we barely knew of the existence of galaxies other than our own. Today not only have we mapped billions of galaxies, we have confirmed the existence of planets orbiting other stars, we question the existence of other possible Universes. Our scientific progress in cosmology has been remarkable.

In this talk, I will present our current understanding of the cosmos leveraging data from the James Webb Space Telescope, the Hubble Space Telescope, the Chandra Space Telescope and ground-based facilities including LIGO and state-of-the-art modeling and computation . Even as our understanding has evolved dramatically, many open questions remain. I will close by outlining the areas of research that offer exciting discovery opportunities in the near future.

A Great Riddle and the Quest for its solution

Good problems and questions are the lifeblood of any subject. Modern mathematics can seem very abstract, abstruse, and forbidding. But its elaborate theoretical structure has often been developed in response to the challenge of a problem that resisted solutions for decades or even centuries. I will talk about a problem posed by Pierre de Fermat in 1637 which was resolved more than 350 years later by Andrew Wiles in 1994. The problem is misleadingly called Fermat's Last Theorem. It is very unlikely Fermat had proof of his assertion that the equation X^n+Y^n=Z^n has no solution in positive integers X, Y, Z as long as the exponent n is bigger than 2. (It would be more accurate to call it Fermat's Conjecture or Fermat's Problem!)

p class="gis-para"> I will talk about how Fermat's problem acted as a muse to number theorists and led to the creation from scratch of new techniques and fields of mathematics that in the end became an integral part of Wiles's proof. Fermat's problem is more of a riddle than of theoretical importance to mathematics, but it inspired mathematicians to come up with new ideas that are now at the heart of modern mathematics.

Thus my talk will be about the importance of good questions that can take mathematicians on a long journey (sometimes lasting 350 years!), and lead to significant discoveries of greater importance than just their application to answering the question. Wiles's very 20th-century solution of Fermat's 17th-century solution is a great example of this.

Chemistry is Fun!

Chemistry is an experimental science, and an important aspect of chemistry teaching is to demonstrate appropriate experiments. Some experiments selected for demonstration are often unsafe experiments, producing toxic fumes and/or toxic waste. This issue of safety is often compromised in many teaching laboratories! In the present-day scenario, we have the advantage of demonstrating videos of experiments done under safe conditions, and carrying out simple, safe experiments using easily available ingredients.

This 'show' will highlight that Chemistry is the central, creative, and useful science. A few basic principles of chemistry will be discussed with simple experiments.

How the Brain is Made?

A tiny bacterial cell, that of the well-studied bacteria Esherchia coli, is about 1 cubic micron. The volume of the cell body of a typical neuron is about 12,000 times more and its axon can stretch up to one meter as in our motor nerves. Yet, the bacterial cell and a nerve cell in our body have many features in common. All cells sense their environment—temperature, chemicals, damage etc. — and respond to these cues. In doing so the cell changes its properties altering the expression of its genes, proteins, metabolites and molecules that send signals outside and to other cells. Studies over a hundred years of how cells of all kinds sense their environment and respond to it have dramatically increased our understanding of the processes involved. Yet, it would also be fair to say that we still are not fully able to move from understanding components of the complexity to be able to predict responses to multimodal inputs, i.e. when many changing parameters are simultaneously sensed by a cell.

If an individual cell poses such formidable theoretical and experimental challenges, what possibility is there in understanding how the human brain works, let alone how the mind is related to the brain? To answer this question, appreciating the complexity of the human brain helps. Our brains have about 85 billion nerve cells and they make over a trillion connections. While different parts of the brain can have specialised function—dealing with vision, smell, movement and so on— the parts also communicate with each other. Thus input information is analysed and analysed information sets are again analysed.

The result is that large brains such as ours can do amazing things. The software that our brains allow to be created— particularly language and other modes of social communication—have made humans unique. With language and the ability to make tools, such as computers, we have moved from being on the planet of the apes to creators of the planet of the apps. Importantly, we have created tools and prosthetics—such as extraordinary computing machines— to understand the universe and can perhaps even get a better understanding of ourselves. Our advances in understanding of the nerve cells, small neural circuits, and of diferent parts of the brain of animals such as worms, flies and mouse are substantial. These studies and studies of the brains of other animals have also pointed to many shared features of higher level functioning that were thought to be unique to human. This is not unexpected, for the comparative study of cells of all kinds and animal tissues—such as the blood, muscles, bones etc.— have pointed to many similar features of development and function. In some levels our brain is not special.

In summary, comparative studies of brain development, function and behaviour is a thriving area of research. The ease of access to data across space and time and our ability to analyze large data sets has grown enormously. These ‘bottom-up’ studies—both hypothesis driven and exploratory—provide for the design and analysis of complex experiments which can test ‘top-down’ theories of brain function in health and diseases. There has also been a spate of divergent theories on how the mind is associated with the brain. Unlike only a few years ago, contrasting and competing theories of mind and consciousness can be better experimentally tested. Finally, as populations age and humans live longer the challenges of healthy ageing are faced by every organ including the brain. Understanding the brain will have important practical value too.
