On our way to Australia, we had spent a couple of weeks in New Zealand and found the character and outlook of the New Zealanders very British. In comparison, we generally found most Australians we met more laid back, quick to tease and always ready for a good time. They seemed, however, especially intolerant to anyone with a ‘better-than-thou attitude’ and even then, anyone from Britain was automatically called a ‘Pommy’, a derogatory nickname from days long past.

Lobsters
When we visited Portugal in 1980, we toured the Algarve's south coast and one day at noon when we were looking for a place to eat, we spied a shabby little hut on the beach with tables and a grassy lane leading down to it. Sure enough it was restaurant with a chalkboard menu in Portuguese and another couple as customers. They were tackling a huge spiny langouste with apparent gusto so when the proprietor came for our order, we just pointed to them indicating we’d have the same.
It was the first time I had ever been up close to, much less tried to eat the intimidating spiny creature that came on a big platter, and it was a bit of a feat figuring out how to tackle it. It was soon obvious however, that it was like the clawed lobster we were used to in that the tail contained most of the meat so we consumed it first. It was a bit tough and not quite as flavorful as expected, but the real adventure was yet to come.
Having grown up on the east coast of Canada, we were experts at finding the tender, delicious bits of meat to be found in a lobster’s body at the base of its legs and, sure enough, exploring the body of the spiny beast was amply rewarding! There were lots of large tasty morsels of meat to be found and especially at the bottom of the huge antennae too. I was tempted, but didn’t eat the tomalley, the loose green delicious paste in the body that was the creature’s liver because, like any liver, it stores all the body toxins.
As we were engrossed in exploring our feast, we were curious to notice that the man at the other table had left his companion and driven off leaving her behind. The reason became clear when we were presented with the bill and found out our lunch had cost us almost $100US [worth almost 3 times that much now] – an unexpectedly large amount of money for lunch in such a setting! - and I too had to stay behind as my husband drove off to the nearest bank.
In recalling this memory, I realized that I still know very little about spiny lobsters so have looked them up to find that there are two main types of lobster in the world that we commonly
eat, clawed lobsters and Spiny lobsters and that they are biologically only distant cousins. Clawed lobsters thrive in cold, shallow waters as far north as Newfoundland and northern Europe and as far south as southern parts of Australia, New Zealand and South Africa. They differ from one another mainly in the size of their claws with the north American coast lobster [shown on the right] prized for its delicious large claws. Interesting that Spiny lobsters are typically found in warm waters and the big one from the Mediterranean that we had eaten was an especially rare treat there.
Looking back now, it still was worth it! Rie

Count Rumford
In 1980, when I decided to spend a Sabbatical year at the Royal Institution in London, it was because of the science being done there. I didn’t realize then that it was the oldest independent research body in the world with a fascinating history! For instance, the story of its founder Benjamin Thompson [later Count Rumford], is worth recounting.
Benjamin started out as a simple farm boy in rural Massachusetts who happened to have had a good teacher who recognized Ben’s talents and arranged for him to attend lectures at Harvard with an older student. Thus when Ben was only about 12, the two used to walk to Cambridge together to attend the lectures of John Winthrop, a science and mathematics professor. That contact introduced Benjamin to the excitement and methods of science and set him on his path of life-long experimental investigations.
Thompson was not only bright but an opportunist and, with his good looks, he did extremely well as a young apprentice to a merchant in Salem. Through this work, he came into contact with and imitated the manners of refined and educated people he had dealings with so that in 1772 when he was just 19, he charmed and married a rich older widow in Concord. Those were the years leading up to the American Revolutionary War and, because of his loyalist sympathies he was forced to flee to Boston where he became a spy for the British.
When Boston fell to the rebels, Thompson sailed to England where he rose in the government and had the opportunity to conduct scientific experiments particularly on the force of gunpowder. This work was published by the prestigious Royal Society and led to his being widely recognized as a scientist.
With the War over and a pension, Thompson traveled on the Continent eventually settling in Bavaria where he was invited to be an advisor to Prince Theodor. Observing many vagrants and idle soldiers in the streets, he set up soup kitchens and adult schools to teach mechanics and other useful trades. As well he devised make work projects, encouraged the growing of potatoes and in general improved the lot of the destitute making him a trailblazer in social reform. He was also a prolific inventor creating many practical applications like kitchen ranges, percolator coffee pots, and lighting devices that helped the poor and homeless. For his work he was granted the title Count Rumford.
At one time he investigated fireplaces by installing glass doors and, through careful observation of smoke patterns, he was able to come up with a device that made fireplaces and stoves draw well. The diagram on the right shows the smoke shelf he designed that turned the downdraft around so that it drew the smoke from the fire up through a narrow opening. As well, the damper in the throat could be adjusted to make the fire burn more efficiently. He also redesigned the firebox with sloping sides so its heated surfaces radiated warmth into the room.
After 11 years in Bavaria Rumford returned to England, made a fortune installing smoke shelves in British chimneys and, with his own money, founded [and supported] the Royal Institution. Its aim was to introduce new technologies [which is now translated as basic research] and to teach science to the general public, which it does to this day.
Though his name may be often recalled in connection with the Rumford fireplace design, he will always be renowned for his important scientific breakthrough that centered on the nature of heat as molecular motion.
Pretty interesting life for a poor farm boy whose mind was opened to new ideas by an early encounter. Rie
