Christmas



The Chemistry World office is bedecked in tinsel, ready to celebrate the festive period. And as a thank you for celebrating with us, we’re going to send a Chemistry World mug to each of our favourite festive chemistrees!

On a recent trip to the chemistry department at the University of York, I spotted a different interpretation of the traditional Christmas decorations…

So we tweeted about it…

On the eleventh day of Christmas, Chemistry World brought to you, the penultimate day of the quiz. And straight in with the first question.

In January, we found out that the caffeine levels in espresso coffees purchased from many coffee shops are well above the recommended daily allowance for pregnant women set by the Food Standards Agency in the UK. What’s is this recommended daily allowance for pregnant women?

The leaping lads clearly have a surfeit of Christmas spirits!

And on the tenth day of Christmas we pushed on with the topical news quiz. Today’s questions to stretch your synapses to breaking point are:

The aforementioned ladies

And on the ninth day of Christmas… my lawyers advised me against making sexist jokes pertaining to the dancing ladies in question. Today’s questions to stretch your memory and your chemical knowledge are:

Why was Chemistry World‘s mild-mannered Phillip Broadwith shouting at queen-of-jam-tarts-and-kindly-old-lady Mary Berry, who presents the programme The Great British Bake-off?

What was Nasa associate administrator John Grunsfeld referring to in August when he said: ‘The seven minutes of terror has turned into the seven minutes of triumph’?

And finally, the answers to yesterday’s quiz. It was the ozone layer that had grown slightly in size. Warmer temperatures have been blamed for the slight increase and the hole is not predicted to return to its 1980s state until 2065. An amazing 5 (five!) litres of carbon dioxide escape from every bottle of champagne. Have a look at our Christmassy feature, Raising a glass to champagne, to learn more. We’ll see you tomorrow at the same chem-time, at the same chem-place.

Why do chemists have reason to fear Bartosz Grzybowski’s ‘Chematica’?

RSC president Lesley Yellowlees said in May that the UK would take almost 50 years to catch up with the US in terms of what? The statistic two out of 44 was also central to this discussion. (more…)

And on the sixth day of Christmas my true love brought to me, six geese a-laying topical chemistry questions. 

Right, I hope you’ve rested your brain over the weekends and you’re ready for more. Off we go.

Chemists had some stern words for Auntie Beeb (the BBC) and James May of Top Gear fame in September. Why?

In August, Nasa’s rover Curiosity landed on the red planet and started making measurements with many different instruments. What type of instruments can be found in ChemCam?
