Which of the following problems is "harder" to solve? Adding two 5-digit numbers or multiplying them? In general, it seems that multiplying is harder, but is there a way to make this feeling formal?
The area of theoretical computer science tries to do just that for any given problem! In this talk, we will look at some examples of such problems and try to see how easy/hard it is to solve them.
Colour is a fundamental aspect of our world, shaping our perception, culture, and experiences. In this talk, we will explore the multifaceted science of colour, tracing its profound influence through history and delving into the fascinating interplay of physics, chemistry, and biology that brings colour to life. We will also discuss the mathematics of colour, which helps us to identify and represent colour effectively! Encompassing various aspects of how light and colour are interconnected, we will illustrate the principles of light dispersion, the visible spectrum, and the phenomena of reflection, refraction, and absorption that give rise to the colours we see. We will explore the chemistry and the molecular origin of colour in pigments and dyes, along with the biology of colour perception, and interpretation highlighting the evolutionary significance of colour. Join for a colourful journey through time and science with demonstrations that will make the science of colour come alive.
