Episode 27: Astronomy on the Web

By Leave a Comment

A different, interesting and at times a little silly episode this week.

Professor Pamela L Gay from the Southern University Edwardsville Illinois (SUEI) and Swinburne Astronomy Online but you will may be familiar with her voice on the probably most popular Astronomy podcast Astronomy Cast.

This recording was made in Oxford during her visit in March this year.

====================================

This week’s quote is from Anne Morrow Lindberg

“Good communication is as stimulating as black coffee, and just as hard to sleep after.”

Episode 26: Antikythera Mechanism

By 2 Comments

Everyone who comes across the Antikythera mechanism goes through a phase initially of disbelief and then the awe inspiring realisation that something almost from another world actually exists in ours.

Imagine William Shakespeare writing Hamlet using a laptop. Surely a ridiculous proposition he was about 300 years too early for that. He didn’t but today’s topic is just as incredible but thanks to the presence of physical evidence- true.

The bronze department of the Museum in Athens has a small device slightly bigger than a pocket dictionary which has spent 2000 years under the Mediterranean Sea. Its is a hand made hand operated mechanical mechanism which may have looked like a multi handed clock. This remarkably compact device can display the calendar, predict eclipses, illustrate the phase of the moon, indicate the position of most of the planets and even takes account of the precession of the lunar orbit. The mechanism is driven by a collection of precision gear wheels made in Greece about 100 BC and nothing like it would be made again for at least another 1000 years.

My thanks to members of the Manchester Astronomical Society who arranged this visit for Tony Freeth to come and talk to them, and Conway Mothobi of the Manchester Metropolitan University hosting the event where this recording was made.My thanks of course to Tony Freeth for making the time on the day.

Episode25:Science and Religion

By 3 Comments

Science is the product of human intellect, creativity and imagination. It helps answers the profoundest of all questions. Where did life come from? How old is the Earth? What is the structure of the universe? How did humans come to be? As the history of science shows, as it progresses so does the nature, accuracy and reliability the answers to such questions. The scientific picture of the physical world is a provisional and an ever changing one.

Science is not the only way to understand the world and our place within it.  Majority of the time humans have existed most of them have been equally content and secure with different answers to the same fundamental questions. For them ancient holly texts provide unambiguous solutions. Science is not needed because it is not required.

The debate between science and religion is as intriguing and contentious today in the 21st century as it has always been. Science progresses by actively challenging its core tenants through the rational exercise of reason. On the other hand religious beliefs have divine origins, don’t require changing and are thus inherently stronger.

There are surprising large number of high profile scientist who are also committed to a particular faith. Perhaps they can shed some light on how they reconcile this apparent contradiction.

Dr Allan Chapman who is not a scientist but a historian of science and a practising Christian with a particular interest in the history of astronomy talks about science and religion.  He is the author of several books including biographies on Mary Summerville and Robert Hook. Perhaps he is better known  for  “Gods in the Sky”  and as the presenter the  of the three part series of the same name on channel4.

New Arrival

By 1 Comment

Amrita Christine May-SinghYou will have noticed that I’m not quite on schedule right now. Indeed have not been so for a few weeks. As a one man band I expect that to happen from time to time. Last week however was special. For the very first time, I became a dad. Both my wife Regine and my daughter – Amrita Christine May-Singh are well and healthy.

I have some projects underway for Astrotalkuk and will resume a more regular pattern in the coming weeks and months.
