Mathematical Model Linking Max Temp and Min Temp

 Having just completed the 'Mathematical Modelling' course by TU Delft I was quite eager to try out applying what I learnt, so I found a dataset on Kaggle (https://www.kaggle.com/datasets/fedesoriano/wind-speed-prediction-dataset?resource=download) and plotted two variables, hoping to find a relationship between them. The variables I decided on were Maximum temperature and Minimum temperature. 

Using Excel, I cleaned up the data set and obtained 5801 workable values.



I then used MatLab to plot these values and then used the polyfit function to try equations of different polynomial orders (1-11). 


After trying all the different orders, a simple linear regression model was found to be the most suitable. 

The model that best links these 2 variables is y= 1.0835x+ 5.6363 where y=Maximum temperature (celcius) and x=Minimum temperature (celcius).

A Brief History of Astronomy's Evolution

"  You have to know the past to understand the present."                                                                                         -Astronomer and Author, Carl Sagan (1980) All innovations and discoveries, no matter how small or large, are all built upon the work and knowledge of predecessors - even Einstein's famous general theory of relativity was only possible due to the foundation built by astronomers throughout the ages! That's why knowing how our understanding of the universe has changed through the ages is crucial for laying the groundwork for any future discoveries. Understanding the challenges and sacrifices faced in order to allow astronomy to become what we all know and love also allows people to gain a brand new admiration for this vast subject. So without further ado, let's get into seeing the history and evolution of astronomy! Fig 1- Geometric Model Born in 100AD, the Greek astronomer Ptolemy established the Ptolemaic geocentric system
