Discussion : Need for calculations

1. Whats the use of calculations?
   1. Helps in predictions.
   2. Makes designs more robust.
   3. Lesser chances of failures.
   4. Helps understand the process and optimize the process (not discussed)
2. Why we don’t do it?
   1. Fear is a big reason. Why do we fear calculations? Because we make errors in calculations. We make errors because either we have less or incomplete information, or we are casual about critical aspects of the process or we are plain lazy. In terms of lack of information, the main reason is we do not have questions that will lead to the right information. And why this? its because we do not think. And why we do not think is because we are not interested. So basically it boils down to if we are passionate about perfection, thats all.
   2. Abstract nature: Sometimes some people are more disposed to act out and learn through experience and repeated failures than doing abstract mathematics. This is the difference between experimentalists and theoreticians. This is the difference between Edison and Tesla. However, we all agree that some amount of basic calculation is required.
3. Need to plan case-studies for future discussions on this subject.

Discussion: What one wants from VADIC?

• Exposure to real engineering with interaction with real requirements of society.
• Chance to be an entrepreneur.
• Chance to work on your own idea.
• Some have all interest and energy to be creative and innovative, but they do not have a direction. They would like to get a direction from working at VADIC.
• Interaction with like minded people.
