It’s that time of the week again: Throwback Thursday! First up, the video above demonstrates what happens when you heat a plastic cup. It’s rather surprising, considering it doesn’t just melt onto the floor. It’s all to do with the way the atoms are arranged.
What follows are six articles from the BBC from the past few years, all to do with atoms. The first article talks about how the atomic bond types can be seen between atoms in a molecule, which is very cool. What is cooler, however, is a short video of a boy and his atom. That’s right, IBM created a movie by manipulating single atoms on a copper surface, and it’s incredible.
Next up, the miracle material graphene. Graphene is a phenomenal material, said to be a the strongest material ever measured, as well as having great flexibility and conductivity. So much so, that a few years ago, it was voted one of the top five recent physics discoveries, along with hadron therapy, quantum computers, superlenses, and kinetic energy harvesting.
What is the world’s lightest material? Back in 2011, it was a material that was less dense than aerogels and metallic foams, however, even that got beaten a couple of years later. Mentioning different types of material, will we ever be able to really have invisibility cloaks? All you need is a material that can grab hold of the light coming from an object, guide light around the hidden thing, and then return it to the path it was going on originally… simple, right?
To research all of this, you need money, or gold. But what gives gold that mellow glow? It’s all to do with relativity, and is actually rather interesting.
That’s it for this week. Atoms, graphene, and gold. Onwards!
