The gentleman pictured is one Mr. Thomas de Prinse of the Explosions&Fire YouTube channel. He recently finished up a synthesis of dimethyl cubane-1,4-dicarboxylate. While this is impressive feat to accomplish with hardware store chemicals in a shed, it is not novel or groundbreaking enough to warrant a Nobel Prize.

Someone has then created this portrait of him, replicating the style often used in Nobel Prize announcements (see this year's as an example), with a few differences, such as misspelling 'Nobel' as 'Noble', substituting 'Swedish' for 'Swiss', and writing 'This is a work of satire.' down the side.

Imagine the most stereotypical Australian you can. Now imagine he has a PhD in chemistry but no money for a lab, so does all his work out of a literal tin shed full of spiders using stuff he found at the hardware store
