I am interested in many areas of math including topology (point-set, algebraic), functional analysis, Banach spaces and algebras, real analysis, complex analysis, measures and distributions, group theory, rings, fields, Galois theory, number theory, graph theory, numeric analysis, special relativity, matrices, non-standard analysis, foundations of mathematics, logic, categories and probably some others I am not thinking about right now!

I love to question basic assumptions and also like to create new connections between different areas. I have been playing with math since I was about 4 years old (my father was a mathematician too) and also grew up playing with computers too.

My favorite math book right now is the Princeton Companion to Mathematics which contains hundreds of interesting articles and has given me many new insights into topics I thought I already knew. :-)

I have bachelor and masters degrees in math from Cambridge University. I started a software company a few years after that, which is still one of my sources of income. I have lived in UK, Holland, USA and now Permanently Traveling in South America. As part of the PT life I sold and gave away 95% of the contents of my house and stored the rest in 2011. I also sold my car. Less is more!

I have many other interests including language learning (currently Spanish!), dance, painting, improv, 2012 changes, honest communication, energy healing, teaching Kundalini yoga, EFT, gender, futurology, history (especially of WWI and WWII), alternative history, reading science fiction and mystery books. Just like in my math investigations I follow the joy!

comment How much cash can you carry in a European Union domestic flight?
The laws in individual countries on the use of cash for payments can be more restrictive. For example it is illegal to pay for goods or services in cash of EUR 1000 or more in Italy. In Greece the limit is EUR 1500. See europe-consommateurs.eu/en/consumer-topics/… for details on all EU countries.

comment Why would Boarding Time be a whole hour before Departure Time?
There is a balance between how early the airline requests and how much time passengers spend waiting at the gate. As there is not much cost to the airline for passengers waiting an extra 30 minutes at the gate they tend to make the boarding time earlier. The argument that is not earlier than needed would still apply if the boarding time was 1 1/2 hours before the flight time or 2 hours... because the flight would still leave on time...

comment Haggling for autos in India
One scam to look out for if you get them to use the meter is if the meter is faked to charge a much higher rate per mile. Or the driver just hits a button when you are not looking that doubles the meter or worse. One time I was haggling prices and the driver said he would use the meter. After the ride and 10x the regular fare I knew why...

comment What documents should you carry with you when travelling internationally?
I read about S.A. vaccination requirements in the health section of Lonely Planet guide for these countries. Try wwwnc.cdc.gov/travel/destinations/list for more details. Immigration asks (when they feel like it)

comment Deportation from Ireland
Thanks for the link on a similar situation. Yes he would be illegal immigrant using this way and if caught the consequences might be high. However the risk of being caught given the open border is in my opinion very low. It depends what he plans to do in Ireland and for how long. If he is a well behaved tourist for a few weeks and returns over the land border I think there is little risk of detection. If he plans to live for months in Ireland with a girlfriend or get illegal work there then the risk of being caught goes up a lot.

comment Why are there no 2,3,4,5 tier bunk beds on airplanes?
I have wanted this for years. I travel in sleeper trains in Europe and Asia and I have seen sleeper buses in Asia too. Perhaps Virgin will give it a try. I would also love to see an area on the plane where you could stretch or do yoga during the flight.

comment What is cheapest way to fly around SE Asia in a circuit - hub with roundtrip tickets or sequence of oneway tickets?
I have a friend in Jakarta so flying there from SIN then on to Bali makes sense to me for other reasons. It didn't seem so easy to fly on from Bali as to round trip back to SIN, at least on AirAsia. I will search for some other ideas on that one.

Thanks for the suggestion of going overland for Bangkok-Laos-Cambodia-Vietnam. I find I see so much more of the country when I travel by land, meet more ordinary people too and can save money on the trip. Though the air tickets are so cheap not sure on that part. Or how long "by land" takes here?
