Computer scientists credit Turing with formulating the philosophical principles that power every computer and smartphone today. Researchers in artificial intelligence, meanwhile, label him the founder of their field. Chemists say Turning predicted the existence of reactions that change colour in a periodic fashion before these had ever been observed.</p> Mon, 23 Jun 2014 14:12:14 +0000 Joe Schwarcz PhD 2156 at /oss /oss/article/food-health-you-asked/why-iodine-added-salt <p>When back in 1811 Bernard Courtois noticed the violet fumes produced when his seaweed extraction tank was being cleaned, he could have never dreamed that he had set the stage for one of the most important nutritional interventions in history. Let’s backtrack a little. Courtois owned a factory that produced potassium nitrate, better known as saltpetre. This substance was a major component of gunpowder and was in great demand by the military. One source of potassium nitrate was vegetable matter and Courtois had found that decaying seaweed fit the bill nicely.</p> Wed, 07 Nov 2012 19:16:11 +0000 Joe Schwarcz PhD 1777 at /oss /oss/article/health-history-you-asked/what-role-iodine-thyroid-function <p>“Take a dose of seaweed or burnt sea sponge twice a year!” That was the ancient Chinese remedy for goiter. Almost four thousand years ago Chinese medical writings described the troublesome swelling of the neck we know as goiter and noted the remedy which had somehow been arrived at through trial and error. Of course Chinese physicians had no idea why it worked, but work it did. Later Hippocrates and Galen gave the same recommendation and by the 12th century the treatment was taught in the School of Salerno, one of the first formal medical schools.</p> Sat, 10 Nov 2012 01:38:39 +0000 Joe Schwarcz PhD 1779 at /oss
