Terms physicists and biologists use differently

[Ryan_m_b]

I'm giving a presentation to a group next week made up of mathematicians, physicists and mechanical engineers. My talk is going to be related to my work so it's going to be very biology based. I want to start the talk pointing out that life science and the physical sciences are very different in their cultures and I thought it would be fun to have a slide with terms both use but completely differently. The point of this is to lead on to saying that if at any point I'm using a term that you know but don't see how it fits then feel free to ask.

Examples I have so far are vector, plasma and differentiate, can anyone think of any others?

How about translation?

 

[Nugatory]

Evolution (of a physical system versus a species); decay; selection

That's a good one, thanks

Maybe, I'm leaning more towards ones that won't be obvious or well known if possible. The vector example I got from a lecture recently in which a class of mechanical engineering students hadn't heard of a disease vector before.

 

[Pythagorean]

free energy

edit: that was a joke, referencing pseudo-science, but I immediately realized that physicists also use free energy in thermodynamics.

nucleus
cell
filament
plasma
conjugate
bifurcation
degeneracy
corona

Is "perturbation" used in life sciences in some technical sense?? If it is, I'm sure it means something else than within physics/maths.

As a general strategy here,I would suggest that you should look at semi-colloquial Greek/Latin loan words that are used in a technical sense, and compare actual technical usages to discover subtle differences in implied meaning.

gaussian and normal

Real

Complex
Manifold (this one has the nice property of being different for mathmatics, ME, and general use)

Perturbation: "In physical therapy, an external force applied to a person's center of mass in an attempt to move it from the base of support "

These probably apply more to chemistry than biology, but: solution, precipitate, reduction.

Also, statistical significance.

 

[Dembadon]

"Proof"

 

[kith]

Population

The vector example I got from a lecture recently in which a class of mechanical engineering students hadn't heard of a disease vector before.

That reminds me of a joke I saw recently:

Q. What do you get when you cross a mountain-climber with a mosquito?

A. Nothing: you can't cross a scalar with a vector.​

I had to look up the biological meaning of "vector" before I understood the joke.

:rofl:

Okay, that has *got* to be Ryan's first slide! Too funny!

"Theory".

(I don't think there are any universally accepted definitions, but...)

Physics: A piece of mathematics and some correspondence rules that tell us how interpret mathematical results as predictions about results of experiments. (Short version: "Something that makes predictions about results of experiments"). If the predictions are bad, then it's a bad theory, but it's still a theory. If the predictions are very accurate, then it's considered a good theory even if we're not sure that it really explains anything.

In other sciences: Something that explains a fact. (People often say that it's in this sense that the theory of evolution is a theory).

Outside of science:
1. A statement that's believed to be true.
2. A guess.

These are all great everyone thanks! I probably won't need any more but feel free to keep them coming for interests sake.

Haha I am definitely stealing this for once I've explained vector!

Does that mean I'm unknowingly a biologist?

Membrane: in biology, almost always refers to cell or organelle membrane, whereas in Physics, the use is broader. In String Theory, "membrane" (or "brane") may have another arcane definition.

Kinetics: In biology, may refer to enzyme kinetics or sometimes "time-kill kinetics" in microbiology. In Physics, used as a singular form to refer to something related to motion.

Weight: Almost always used as a surrogate for mass in Biology. In Physics, has a very specific meaning relating to the gravitational force on a mass.

Matrix: Used to denote the surrounding substance that envelops something else which can be a cell or an analyte (e.g. extracellular matrix, or specimen matrix). In maths and physics, matrix has a whole other meaning.

Genus: You know the taxonomic use of the term. It's used differently in topology (which I think also has applications in physics).

Differentiate: In biology, used to speak of the specialisation of cells. Different from the mathematical meaning. Of course, there can be quite a lot of calculus in biology, as well.
