Building practice into theory

Few case studies

‣ Generalcomputation

‣ Simulatingdynamicalsystems

‣ Buildingapproximatelinearmodels

‣ Frequency-domain(spectral)analysis

‣ Handlinguncertaintiesandparameterestimation

HIGH SCHOOL EDUCATION

EquationsPure sciences

Trained for solving exact and pure problems


ENGINEERING EDUCATION: CURRENT PRACTICE

Maths & Sciences taught as pure subjects - zero emphasis on applied aspects!

Theory courses followed up with lab sessions across semesters

Pure software courses (e.g., in MATLAB, ASPEN, etc.)

Very little emphasis on intuition and perspectives

Drawbacks:

‣ Cannotplacemathematicsandsciencesincontext

‣ Disconnectbetweentheoryandpractice

‣ Theoryisnotunderstoodandpracticeisboring

‣ Graduationwithoutrealisation

Show how math and sciences, blend and get into action. Teach how probability and statistics are useful!



1. How do equations get into action! (Equactions?)

2. How to deal with uncertainties?

3. How to estimate?8
