Motivation class for freshers (B.Tech)

What is Science ?
Why Should we learn ?
How can we Understand ?
Does Science Know everything ?

if not what would we do ?

Scientist and their thought process were briefly explained

7. What is SCIENCE. ? The pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence with logic. What I understand in a systematic way……. The word   science  has been used in  Middle English since the 14th century in the sense of " the state of knowing ". The word was borrowed from the Anglo-Norman language as the suffix  - cience , which was borrowed from the  Latin word   scientia , meaning "knowledge , awareness, understanding"

9. Why should we learn/Know The goal of science is to advance our understanding of the world and improve our lives (Mankind) through evidence-based knowledge and innovation. Science is Describes how to understand the problem in the world(principles/rules) Technology is creates the products following the Science by engineers to solve the problem

10. Unfortunately, many philosophers and scientists in ancient days faced persecution , imprisonment, and even death for various reasons, including: Challenging authority: They questioned established beliefs, traditions, and authority figures, which threatened the status quo. Heretical ideas : Their ideas were deemed heretical or contrary to prevailing religious or philosophical dogma. Fear of change : Their discoveries or ideas threatened to upend traditional power structures or social norms. Misunderstanding and fear : Political and religious conflicts: Socrates ( ancient Greek philosopher) - Hypatia ( ancient Greek mathematician and philosopher) - Giordano Bruno ( Renaissance philosopher and scientist) – Freedom of thought and expression- Open-mindedness and tolerance- Critical thinking and intellectual curiosity-

11. 1548-1600 was an Italian philosopher, poet, alchemist, astronomer, cosmological theorist and esotericist 1473-1543 Poland

12. Earth at the center of the universe. 2 nd CE Johannes Kepler was a German astronomer 1571-1630

13. Darwin& Alfred Russel

14. Batteries Source of power ED/ECD Consist two (2) electrodes Anode (+) Cathode (-) Oxidation Reduction OIL - O xidation I s L oss in terms of e- RIG : R eduction I s G ain in terms of e- Primary Battery Non Rechargeable Ex: wall clock, watches, toys etc . 2 . Secondary Battery : Rechargeable Ex : Mobile, Lap Fuel Cell Methanol- Oxygen Hydrogen -Oxygen Redox

15. The backwardness of the nation is the root cause of Blind believes Superstitions Following Irrational Things Lack of Scientific Temper Lack Of Logic Lack Of Critical Thinking Not giving importance to practical/research v/s western Authorities promoting Traditions/Religious ideology Constantly we have to avoid all the above and improve scientific temper to the students
