Read the essay 'On science and uncertainty' on pages 28-29 and post a blog entry in which you share you personal reflections using the following 'visible thinking' framework: 


1. CONNECT to what you already knew 
2. EXTEND: What new ideas did you get that EXTENDED or pushed your thinking in new directions? 
3. CHALLENGE: What is still CHALLENGING or confusing for you to get your mind around? What questions, wonderings or puzzles do you now have?


What is science?
Science is a systematic study of the structure and behavior of the physical and natural world through observation and experiment. However, it isn't always necessary for science to be true. People actually question the knowledge of science. "Science is founded on uncertainty." (Quotes form Lewis Thomas)  
Therefore, we can not easily trust a new research's finding and conclusion because science is not just consisting of facts but also errors and this errors could lead to a new discovery but it is actually wrong because it has a "error" hence, it isn't necessary to believe a new research just because it is based on science. 
What really amazes me is how people still believe in the conclusion stated by scientists just because they used theory to prove it. Like don't people see that those scientists are humans and they also tend to make errors. So why do they believe any scientific fact in seconds without thinking twice about it?
