The atom is the most quintessential symbol in science.  It is commonly drawn as a circle with smaller circles orbiting it. What do those circles represent? And what are those circles made of?

Atoms may make up the world around us, but let's be curious and ask, 'what are atoms made of?'

What do bonds look like?

From secondary school onwards we are taught that the world around us in made from atoms and those atoms are held together by bonds. As we get older we are introduced to the different types of bond: covalent, ionic, and metallic. We are also told about hydrogen-bonds, though these don't join atoms together as the other types do.

We are all used to the diagrams we see for bonding, but is that what an actual bond looks like? Until recently the answer was a decisive, 'we don't know'. No one, not even scientists, had ever seen a bond. No one had ever seen an atom. We had calculations and theories saying they were there, but no actual visual of them until recently.

In the first 'Images on Monday' post, let's be curious and ask 'what does a bond look like?'

Sometimes understanding the science behind something will not only benefit you intellectually, but physically as well. Sunscreen is one of the those cases. By knowing how sunscreen works you'll understand why you need to use it and in what way. So let's be curious and find out how sunscreen works.

Who were Marie and Pierre Curie?

Recipient of 2 Nobel Prizes, discoverer of 2 new elements, saviour of countless lives; Marie Curie is perhaps the most famous of all female scientists. Her scientific successes are interesting in themselves, but a look into the life and times of Marie Curie provides a fascinating lens through which to view them. Her personal life involves courage, tragedy and even a duel—more fitting for a Hollywood romance film than a scientist.

But as wonderful as Marie Curie was, she didn't work alone. In one of the great scientific partnerships, her husband, Pierre Curie, did research alongside her. Together they shared, alongside Antoine Henri Becquerel, the 1903 Nobel Prize in Physics.

Today (26 July 2014) is the 119th anniversary of Pierre Curie and Maria Sklodowska's (Marie Curie) marriage. So, to celebrate this special day let's be curious and find out who the Curies were.
