Learning by simulations

The airline industry were amongst the first to use simulations for learning. At Asian Aerospace today, I asked 3 of the simulator exhibitors to give me a fly, but they politely refused. Damn - it would have been a lot of fun: One of the exhibitors was showing this scenario-based simulation for military training: Learning […]

It wasn't all about the military at Asian Aerospace today. The Airbus A380 was there - an impressive piece of machinery: And in the flesh, sporting the livery of Singapore Airlines (when SIA finally get one, it will be the world's first in service): These guys were enjoying the airshow. The show didn't work all […]

Mine’s bigger than yours

The Asian Aerospace / Asian Defence Technology event at Changi today was more disturbing than enjoyable. What is it with this crazy world? Governments and revolutionaires are willing to pay billions for incredibly sophisticated weapons. If the wealthy countries (especially the US) took only 10% of what they spend on military hardware and spent it […]

Often, it is just due to ignorance about how to properly reference sources. But a key issue is why plagiarism occurs in the first place. Often, […]

Squidoo - it’s Wikipedia on steroids

Squidoo is an interesting knowledge management concept. It is similar to Wikipedia in that anyone can contribute, but it is different in that there can be several pages (called "lenses" in Squidoo-speak) on each topic. Squidoo is an interesting place to explore. You will come across the current most popular topics ("sushi", "cartoons", "online poker" […]

No one can teach mathematics

What’s worse - the dentist or math?

The Americans continue to worry about the state of their nation - especially what it means for the future with China and India experiencing rapid growth.

ZENetic Computer

I went to an interesting series of talks on art and technology at the Singapore Science Centre yesterday. The opening talk was by the highly-cerebral Tosa Naoko (土佐 尚子). She showed a movie about the ZENetic Computer which she co-developed. ZENetic Computer attempts to teach the user about Zen Buddhism, Japanese culture, ink paintings and […]

Missed opportunity

China and India are hell-bent on "catching up with the West" and building pollution-spewing cars. We will be stuck with $50+ per barrel oil and world instability as a result for a very long time. Why don't they take the opportunity to pour money into development of fuel cells or hybrid cars and tax the […]
