Projects

All projects can be viewed on my Github .

• Topics in Undergraduate Mathematics (in progress)

  These are notes I am taking when studying undergraduate mathematics.

• Mathematics Olympiad: A Guidebook (in progress)

  These are notes comprising various topics in mathematics olympiad.

• Different Sizes of Infinity

  I designed a poster for Mathematics Week 2024 exploring the concept of infinite set cardinality. The poster introduced countable and uncountable infinities, illustrating key ideas such as Cantor's diagonal argument and the continuum hypothesis to spark curiosity about the nature of infinity.

• Analysing Happiness: Understanding Determinants Across Global Contexts

  I conducted a linear regression analysis on data from the World Happiness Report 2023 to identify the most significant factor influencing a country's happiness.

• Fires and Hotspots

  I analyzed fire hotspots in South Sumatra using Sentinel-2 and FIRMS datasets to identify high-confidence fire zones. I processed multi-spectral satellite imagery and used True Color, False Color (NIR), and SWIR composites to visualize smoke plumes and burned areas. I presented my findings at the Space Faculty Remote Sensing Workshop in 2023.
