 \maketitle
-\begin{frame}{Why do we have to start frome here?}{We already know what math is}
-  \begin{itemize}
 
-  \item there's no conses on the definition of mathematics but I'll give you mine
-    \item interconnected web of mathematics, how an idea in one field drives you to others
-  \item asking the right question
-  \item We learned about the basics of LLVM and MLIR
-  \item We created a basic platform to develop a programming language, that includes:
+\begin{frame}{Why did I choose to make this?}{}
+  \begin{itemize}
+  \item Originally I just wanted to start from logic
+  \item I read a tweet which made me think not everyone knows what math really is
+  \item I started to ask around online and even on the street
     \begin{itemize}
-    \item A parser
-    \item A JIT engine
-    \item A code generation pipeline
-    \item and few other bits and pieces
-    \end{itemize}
-  \item BUT we didn't come up with a specification for \href{https://serene-lang.org}{Serene}
-  \item We didn't design the language yet
-  \item That's what we're going to do in this series
-  \end{itemize}
-\end{frame}
-
-\begin{frame}{Specification}{}
-  \begin{itemize}
-  \item Not all the programming langs have specification
-  \item A spec or standard brings clarity for users and developers
-  \item We could've just implement an already exist spec like \href{http://www.r6rs.org/}{R6RS} (Scheme)
-  \item Or just create a language based on our intuition (many languages have done this)
-  \item Or design a standard from scratch \\
-    We can use about 100 years of Mathematics and Computer Science to our benefit
-  \end{itemize}
-\end{frame}
-
-\begin{frame}{Where to look?}
-  \begin{itemize}
-  \item Based on the past experience we have some initial idea on where to look
-  \item Later on we will find out whether or not our initial ideas were good
-  \item For example
-    \begin{itemize}
-    \item I prefer functional programming
-    \item Dynamic type systems
-    \item \ldots
-    \end{itemize}
-  \item We can start from there and study what we think is true and also any alternative to them
-  \end{itemize}
-\end{frame}
-
-\begin{frame}{Where we want to look}
-  \begin{itemize}
-  \item There are few major theories we can start from:
-    \begin{itemize}
-    \item Type theory
-    \item Category theory
-    \item Proof theory
-    \end{itemize}
-  \item They all describe the same world from different perspectives
-  \item Also, there are few papers that we need to look at, like the lisp paper
-  \end{itemize}
-\end{frame}
-
-\begin{frame}{Required tools}
-  \begin{itemize}
-  \item We need build up few mathematical skills
-  \item E.g We need to learn:
-    \begin{itemize}
-    \item Logic
-    \item Set theory
-    \item and discrete mathematics in general
+    \item To my surprise majority of people got it wrong too
+    \item Even other engineers and scientists
     \end{itemize}
   \end{itemize}
 \end{frame}
 
-\begin{frame}{The Plan}{}
+\begin{frame}{What was the tweet all about?}{}
+
+\end{frame}
+
+\begin{frame}{Why do we have to start frome here?}{}
   \begin{itemize}
-  \item I like this series to be self contained as much as possible
-  \item We're going to start from basics
-  \item We will cover
-    \begin{itemize}
-    \item What is mathematics? and why do we need it?
-    \item Mathematical thinking
-    \item Discrete mathematics
-    \item $\lambda$-calculus
-    \item Type theory
-    \item and the rest
-    \end{itemize}
-  \item We will study the history of computer science an mathematics as well
-  \item History is a great guide
+  \item Understanding Mathematics helps us to think better
+  \item To asking the right question
+  \item There's no consensus on the definition of mathematics but I'll give you mine
+  \item My goal is to get you think
+  \end{itemize}
+
+\end{frame}
+
+\begin{frame}{So, What is mathematics?}{}
+  \begin{itemize}
+  \item ``Mathematics is the language in which God has written the universe''
+  \item To put it simply Mathematics is a language with specific set of properties
+  \item Usually a language enables us to express something
+  \item For example musical notation is language to express music
+
   \end{itemize}
 \end{frame}

+  Any one who speaks the language of musical notations understands this sheet

+\end{frame}
+
+\begin{frame}{Not just a language}{}
   \begin{itemize}
-  \item I'm not a professional mathematician
-  \item I'm just sharing the result of my research and things that I learn. Take it with a grain of salt
-  \item ``Nullius in verba''
+  \item But it's not just a language, it's a language + reasoning, it's a tool for reasoning
+  \item It's big collection of some people careful thoughts
+  \item In form of provable statements
   \end{itemize}
 \end{frame}
 
+
+\begin{frame}{So, What is mathematics?}{}
+  \begin{itemize}
+  \item By Mathematics it is possible to connect one statement to others.
+  \item Mathematics is a way of going from one set of statements to another via reason.
+  \item It's an interconnected web, how an idea in one field drives you to others
+  \end{itemize}
+
+\end{frame}
+
+
+\begin{frame}{What are those statement all about?}{}
+  \begin{itemize}
+  \item Humans are pattern recognizing machines (We will talk about it more in the episode)
+  \item Mathematics is all about generalizing those patterns via abstractions
+  \item Usually there are more than one way to describe the same thing
+  \item different between doing math and usign math
+    \begin{itemize}
+      \item Mathematicians want to make their reasoning as general as possible
+      \item But math users usually want special cases
+    \end{itemize}
+  \end{itemize}
