On Sunday I am speaking at the Skeptics in the Tron event in Glasgow. Hope you can make it!
So, to the puzzle. Two word puzzles this week.
First, an easy one. What chemical compound is represented by the following…
Second, the letters of the alphabet can be grouped into 4 distinct categories. According to these categories, the first 13 letters of the alphabet would be classified as follows:
Category 1: AM
Category 2: BCDEK
Category 3: FGJL
Category 4: HI
Can you place the remaining letters in their correct categories?
As ever, please do NOT post your answers, but do say if you think you have solved the puzzles and how long it took. Solutions on Monday!
