Many things in Elements are based off of things in real life, from historical events to science theories. For a long time I've wanted to make a list of these and put them somewhere where people asking 'Who is this Schrodinger?' or the like might have a place to learn some connections to Elements.
I'm not very good at writing little non-fiction synopsis, and most of these will be done little by little through the internet, so post here if there's things you think should be changed, added, or removed. I'll try to add one or two new things a day for a while.
ElectrumIn-game: Non-card - Currency || Also applies to Electrum Hourglass
In real-life: Electrum is an alloy of gold and silver, often with traces of platinum, copper and other metals, that is found naturally or made artificially. In Ancient Greece, it was considered white gold, despite being a pale yellow, as opposed to refined gold. It was also used in other parts of the Eastern Mediterranean, from currency to pyramids. It was considered harder, more durable, and easier to refine than pure gold or silver.
QuantumIn-game: Non-card - Resource || Also applies to Quantum Pillar
In real-life: Quantum, in physics, refers to the minimum amount of any physical entity involved in an interaction, while quanta refers to a multiplication of this amount. Beyond this is a fundamental notion that a physical property, such as the energy transfer of basic particles or matter, can be quantized, meaning that it's magnitude can only take discrete numbers. A quantum can be viewed a discrete packet storing energy inside it.
Maxwell's DemonIn-game: Card - Creature
In real-life: Maxwell's demon is a thought experiment created by Scottish physicist James Clerk Maxwell in 1867. It demonstrates a hypothetical possibility of a violation of the Second Law of Thermodynamics. A container is divided into two by an insulated wall that can be opened and closed by said demon, so that all the hot molecules flow to one side, causing the other to cool down, therefore decreasing entropy and creating a paradox of sorts.
Schrödinger's CatIn-game: Card - Creature
In real-life: Schrödinger's cat is a thought experiment developed by Austrian physicist Erwin Schrödinger in 1935. The theory is that a cat is placed in a closed box with a vial of poison, radioactive source, and Geiger counter. When the counter detects the radiation, the poison is released and it kills, or doesn't kill, the cat. One interpretation of quantum superposition suggests that because you cannot see inside the box, the cat is
both dead and alive; however, upon opening the box, it is revealed the cat is
either dead and alive.
