The exclamation ‘Eureka!’ was allegedly uttered by the ancient Greek scholar Archimedes as he got into a bath and noticed the water level rise, suddenly realising the volume of water displaced must be equal to the volume of the part of his body submerged. Consequently, Eureka (Greek: Εύρηκα) has become an interjection used to celebrate a discovery or invention.

It’s also the name of The National Children’s Museum in Halifax which I visited with my family today. We first visited earlier in the year, but thought it was about time for a return visit; especially because you ‘pay once, then play for a year’ with an annual pass. There’s lots of interactive fun for all ages of children, and adults are not admitted unless accompanied by a child – so it’s a safe space.

The focus is on learning through play. It’s run as an educational charity and not-for-profit organisation. It’s aimed at families with children aged 0–11 and encourages hands-on inter-generational learning.

We had a great day, even though it was a long drive, and can wholeheartedly recommend it. No doubt we’ll be there again before our passes expire.

How to Build a Universe
















I always like to be reading a popular science book, and I’ve recently finished this excellent book by Professor Brian Cox & Robin Ince. It’s based on the acclaimed BBC Radio and podcast The Infinite Monkey Cage. It’s witty and comedic, an irreverent celebration of science and the wonders of the universe; totally silly in places and incredibly thought-provoking and mind-blowing in others.

Having three young children has meant that my reading habits have declined of late, but this was one of the books helping me get back into it; not least because this one is in a magazine format with diagrams, photos and lines drawings enhancing the text and dividing into manageable size chunks.

The title The Infinite Monkey Cage comes from the infinite monkey theorem which states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare. In fact, the monkey would almost surely type every possible finite text an infinite number of times. However, the probability that monkeys filling the observable universe would type a complete work such as Shakespeare’s Hamlet is so tiny that the chance of it occurring during a period of time hundreds of thousands of orders of magnitude longer than the age of the universe is extremely low (but technically not zero).

Astronomy Picture of the Day


I’ve always had an interest in astronomy; it goes right back to my childhood, and it’s nurtured my love of science as well as my outlook on life. I’ll probably write about it in the future. In the meantime, one of the websites I visit on a daily basis (as well as the BBC and Facebook amongst others) is Astronomy Picture of the Day. Every day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. I often bookmark some of the best ones, although you need to save the link in the archive rather than the main page (otherwise you get taken back to the main page in future).

Footnote: As I was writing this the death of Gene Cernan, the last man to walk on the moon was announced. “We leave as we came, and, God willing, we shall return, with peace and hope for all mankind.” – Cernan’s closing words on leaving the moon at the end of Apollo 17.
