Examples of science metaphors

A topic in public science

A metaphor is a figure of speech where one thing is said to be another – as an implicit way of suggesting a comparison. (It is implicit, as the person hearing/reading the metaphor is expected to realise that the statement is not meant literally, but poetically.)

Read about metaphors in science

A simple metaphor is just a word or phrase used figurativly, but sometimes the metphor is extended to several realted words/phrases. (Some examples of extended metaphor are indicated *)

spinal cord injuryRP: "…before the rehabilitation, all these damaged nerves are sort of screaming to try and get the message through to the legs, but it is not working. But, the, some of the nerves learn that they can actually do this, and the other ones become less loud. In other words you are sort of retraining those nerves almost."
JB: "Exactly, so if you look at this nerve, it is probably not dominant when you have this lesion and all the others are speaking very loud and they cannot really make a proper signal, and then, with the rehab, this nerve is taking the lead, and is shutting down the others. So that is why probably there is less activity, the others stop talking and this is the one that is now talking the loudest and that is helping for the movement."

star systems"Regardless of what these planets are like, their existence in resonant orbits alone is notable. Theory suggests that the planets formed in these resonances.

water volesGV: "What sort of part of the jigsaw puzzle does it complete to bring this species back in particular?"
AL: "They are a missing part of the food chain. So, through their burrows they will dig up through the soil, they will bring soil nutrients to the surface, which helps with vegetation. They themselves are consumers of vegetation, so they'll nibble bits of plants, leaving room for other plants to come through so changing the plant composition of the banks. And Then, of course, they are a food source for predators, so foxes, herons, otters, hopefully not mink, we hope that we've not got mink here anymore, but also birds of prey so you know, really vital part of, the missing Mars bar, essentially, of the food chain."

astronomy
"Astronomy is thus a four-legged animal standing on sound and false ideas at the front and sound and false observations at the rear. Amazingly, the beast can limp forward, sometimes even gallop, from one discovery to the next. And lurching on its way to valuable information about the nature and history of the universe it has in passing exposed the character of those ephemera, the tails of comets."Nigel Calder
The Comet is Coming! The feverish legacy of Mr Halley
antiquity of species"If, as Pauling and Zuckerkandl speculated, proteins evolved at a constant rate, you could use differences in the sequence of proteins to calculate the time that these species shared [a] common ancestor….Proteins in the bodies of different species could serve as a kind of clock for understanding evolution: no rocks or fossils would be needed to tell the time in the history of life. This idea, so utterly outrageous when it was first proposed, is now known as the 'molecular clock' and is used in many instances to calculate the antiquity of diverse species."Neil Shubin

cell death"…the caspases take an active part in dismantling the cell. They rip apart its internal scaffolding, shred the proteins in the nucleus and put a 'cease and desist' on the cell's DNA repair mechanisms.

comets"Comets…obtrude because they jaywalk across the paths of planets."Nigel Calder
The Comet is Coming! The feverish legacy of Mr Halley
comets"If the 'new' comets seem to be coming from starting points half a light-year out, that is where they have been in residence since the birth of the Solar System. Such is the leading idea about the origin of comets, that is to say the theory not disfavoured in Cometsville. All the other other categories of comets are, in this scheme, pilgrims from the coolest provinces of the Solar System who lost their return tickets and are trapped in shorter orbits around the Sun, waiting either to perish in the heat or to be evicted into interstellar space and exiled from the Sun for ever. But the theory requires the existence of a large population of unseen comets to sustain the pilgrimage, and thus it endorses the opinion of Johann Kepler that 'there are as many comets in the sky as fishes in the sea'.
The devotion of comets to the gravitational faith that unites the Solar System appears in this: their first journeys from the outer darkness to the altar of the Sun take a very long time indeed, for the sake of a fleeting visit. When the priests of this faith, the celestial mechanicians on the Earth, interrogate 'new' comets now arriving in the Space Age they admit to travelling for several million years."		Nigel Calder

comet sampling"It was soon seen that the dust had produced distinctive carrot-shaped burrows into the aerogel collector that were a few millimetres in length, making some of them easy to spot in the laboratory. On closer inspection, however, there was a slight problem. As the particles had burrowed their way into the aerogel it was found that they'd tended to break apart. Little bits and pieces of the dust ended up being deposited all along the inside surface of the burrows. Often at the very end, having excavated its way right into the aerogel, would be a tough piece of rock that became known as the 'terminal particle'."Natalie Starkey

gene regulation"Recall that there are molecular switches across the genome that, under the right circumstances, turn genes on and off. Most of these switches lie right next to the genes they activate. Since progesterone is the trigger for the formation of decidual stromal cells, then we could reasonably assume that the switches would be responsive to it. The genetic switches would be tethered to a sequence that recognized [sic] progesterone.

light"A photon begins its life, travels – potentially for billions of years – and then is destroyed. Each end of its existence, birth and death, involves an interaction with matter. It's the electrical charge of the electron that creates the photon in the first place, kicking off the elegant dance between electrical and magnetic components that Maxwell first described. And it's another electron's electrical field that wipes it out at the end. Q.E.D.

nerves"In 1886, in the process of researching a cure for malaria, against which the dye [methylene blue] did prove to be effective, German scientists and eventual Nobel laureate Paul Ehrlich discovered that this strange and potent blue liquid would selectively stain the nerve cells of the frogs he dissected, and thus seemed to have an affinity for nerves, the motorways and byways of everything we feel and are."Lauren Slater, The Drugs that Changed our Minds. The history of psychiatry in ten treatments
neural connectivity"So it could be that the way antidepressants make up feel better is by helping the brain grow a richer, thicker forest of connections, which enable us to think faster and with more acuity. This line of reasoning stands in absolute contrast to what Whitaker and Glenmullen have found in their analysis of many outcome studies which all seem to show antidepressants burning the brain"Lauren Slater,

psychiatric medicines"Lithium, therefore, was the first 'magic bullet', a site-specific drug, or at least a symptom-specific drug…
unlike the 'dirty' drugs that had preceded [the selective serotonin reuptake inhibitors]. Lithium, it could be argued was psychiatry's first clean drug, modifying a discrete set of symptoms without spread or stain."

science

"The ideas of early scientists often seem crass because science is a garden where theories grow in a bed of facts, and errors are eventually weeded out; we have acres of facts that were quite uncultivated three hundred years ago, and, as a result, any third class graduate of the twentieth century knows far more about the workings of nature that, say, Isaac Newton did."Nigel Calder

sex addiction"These ['sex addicts'] are largely married men who nevertheless seek out prostitutes and pornography, not once a day, not twice a day, but twenty or thirty times in a twenty-four-hour period, men haunted and ravaged by their own internal fires, men eaten alive by uncontrollable desire, men whose brains are likely damp with dopamine coursing down dendrites and being sucked up by axons in a never-ending obsessive circuit."Lauren Slater,

space exploration"Rosetta entered deep-space hibernation from June 2011 to January 2014, just keeping enough systems running to stop it from completely freezing to death. The next big hurdle for Rosetta was reactivation from hibernation – for it to be awoken from its deep-space slumber – something that couldn't be guaranteed.
Luckily, Rosetta's internal alarm clock, which had been ticking since launch all those years earlier, went off at 10 a.m. GMT on 20 January 2014. This triggered a complex series of events to being the spacecraft out of hibernation, which it managed successfully, waking from its coma without the loss of any system. This was lucky because the Rosetta teams had no way to ruffle the spacecraft's covers from Earth. With the alarm clock having gone off, Rosetta activated its core systems such as heaters and avionics, to slowly bring the whole of the spacecraft back to life."		Natalie Starkey

space explorationThe little lander could be forever sat on the side of the comet, wedged in a little shadowy crack, but it was to remain in deep-space slumber. However, the orbiter was still alive and tracking [comet] 67P/C-G through space."
"As we know, the Rosetta spacecraft had to enter hibernation for many months to save power on its ay to catching comet 67P/C-G. The communication-delay time during this mission was up to 30 minutes each way, depending on the distance from Earth, which was fine in the circumstances because the Rosetta teams didn't need to communicate with their sleeping beauty at this stage."

subatomic particles"New subatomic particles arrived on the scene, singly at first but later in battalions. These newcomers had both experimental and theoretical origins, In 1930, the same year that Dirac predicted the antielectron, Wolfgang Pauli came up with another prediction, but for empirical reasons. In radioactive beta decays, the particles that leaving the scene of the crime have less total energy than the particles that went in, and Pauli suggested that the missing energy was carried away by neutral and elusive particles that was also produced in the decay."Lindley, David – The Dream Universe. How fundamental physics lost its way
'superheavy' elements"The superheavy elements – the final 15, element 104 and beyond – have only ever existed in quantities so small they can't be seen by the human eye and can last for less than a second. … They are chemistry's unicorns."

"You can't hold a superheavy element in your hand. Chances are, as you read this, many of these elements do not exist anywhere in the universe. They are chemical unicorns.
But they are unicorns we know exist."

Metaphors employing scientific concepts

Topic/themeUse of metaphorborrowing fromSource
definitions"The mathematicians proudly claimed that striving for unambiguous definitions was one of the 'specific traits of the mathematical style of thinking', and they insisted that a mathematician in linguistics 'plays the role of a litmus test: if a definition satisfied the mathematician, then if must satisfy everyone'."chemistrySlava Gerovitch {historian of science & technology)
linguistics"We do well to be skeptical [sic, sceptical] of a grammarian's systemization [sic, systemisation] when it is full of ENANTIOMORPHISM, the pairing with every category of an opposite which is merely the lack of it."chemical structureBenjamin Lee Whorf {linguist and chemical engineer}
names"Names may begin by suggesting ideas and may not be neutral. But if they are just names they end by being purely conventional tags or identification marks – sometimes very inadequate ones as in the cases of 'real number', 'imaginary number' and 'irrational number', fossils of a mistaken philosophy of mathematics."palaeontologyMario Bunge
nuclear power (attitudes to)"Climate change had been there all along: skies had been warming, glaciers melting and seas slowly rising for decades. Until the 1980s, few humans had regarded the beast as a serious threat. No longer. But the only force that was truly able to combat it – according to the movie – was largely regarded as a pariah, beset by a cultural hysteresis that associated it with bombs and meltdowns."physics (hysteresis) Robert P Crease, (philosopher) writing in Physics World
imaginary numbers"Leibniz himself often betrayed an agnosticism about imaginary numbers that was generally alien to him and contrary to the spirit of his philosophy; for he once designated them as an extraordinary hybrid, 'an amphibian between being and nonbeing'."biological classification

From this website:

In the kind of research known as case study, we examine cases that may be considered to (metaphorically) be organisms in the way the case is entangled within a context.

Note on analogies, similes and metaphors.

In practice the precise demarcations between similes, metaphors (and anthropomorphisms) and analogies may not be absolutely clear. I have tried to follow the rule that if a comparison is set out to make a structural mapping clear (even if this is not spelt out as a mapping: e.g., an atom with its electrons is like a sun with its planets) this counts as an analogy. Where I do not think a comparison is an analogy, but the comparison is made explicit ("…as if…", "…like…": e.g., the atom, like a tiny solar system) I consider this a simile. When the audience is left to spot a comparison (rather than a literal identity) is being made (e.g., the oxygen atom, this tiny solar system) I class this a metaphor.

Anthropomorphism may be seen as a particular kind of metaphor where a metaphorical feature implies a non-human entity has human attributes (e.g., meteors can be impetuous).

I reserve the right to reassign some of these comparisons in due course!
