Christopher Nah's Reflection

(1) Plenary Sessions [Day 1]

(a) My key learning points from each session:
1. Importance of water - Dirty and Clean
I have learnt that there are good and bad microbes in the water, with the bad able to cause cholera, typhoid fever, dysentery and brainerd diarrhoea and the good microbes controlloing granulation and SNDPR.

Bad water can have smell, cause infections diseases, chronic health risks, environmental degradation and also societal and economic impacts. Over 1.1 billion people have no access to water, 2.4 billion have bad sanitation, 3.4 dying from waterborne diseases and 2 billion people risking bacterial diseases.

Key economic enablers = Water + Energy;
Irony = economic development can compromise water resources.
Need = increasing need to protect water resources as economics develop.

Water energy consumed:
Water for power: (from coal) 2-3L/kWh
Average household: 30 kWh/ a day = 60 - 90 L/day
Desalination (no pumping) 4 kWh/m^2

There are 9000 billion asia environmental industries and we can make use of technology to create membranes for water reclamation and membranes for water desalination.

2. Revolution of Microelectronics Technology
Asia have became focal point for electronics companies resulted in supply chain moving to Asia. Singapore is the heart of Asia.

In 1936, the first freely programmable computer was created where:
1. Vacuum tubes performed calculations
2. Capacitors stored binary data
3. Punch cards were used for I/O

Semiconductor industry began with germanium, and improved to use silicon afterwards. Integrated circuits (IC) were invented in 1958. The first IC, being size of small finger had:
1. 1 Transistors
2. 3 Capacitors
3. 1 Resistor

Electronics -> Entertainment / Medicine/ Transportation/ Communication.

Some applications of electronics:
Biometric passport
Radio (Wireless connectivity)
Nano electronics
Water (H2O)
Energy (m.c two)

The future of electronics requires "Brainwaves" to innovate and enhance the electronic experience. Some future application:
1. Programmable Blood

3. Biomedical Engineering & Technology

4. IT for Animation

5. Disappearing glaciers, rising sea levels, and why gravity is even more important than you think
