What are some applications of Mathematics to the medical field?
If you're interested in applications of differential equations in the biological/medical area, I suggest looking at Clifford Taubes, "Modeling differential equations in biology"

How many shares does she own?
Actually this is less obvious than it looks. GE's stock split several times, most recently a 3-for-1 split on May 8, 2000. There was a time on June 22, 2000 when the stock price was approximately \$ …

Can any function represent something in the real world?
Functions in the modern sense of the word are much more general than the expressions that you seem to think of as "functions". In particular, most functions (in the sense of cardinality) cannot be s …

Are questions of convergence important in real life?
Whenever you use a numerical method to approximate something, you'd like to know that your numerical answer will be close to the actual value. A common situation is that the numerical approximation i …

The Significance of Linear Approximation
It very often happens in applications that a model produces equations that are extremely difficult or impossible to solve.
However, some of the factors are more important than others. …

Interpretation of definite integrals
Whenever $f(t)$ represents a rate of change of something, $\int_a^b f(t)\ dt$ represents the total change from $t=a$ to $t=b$.
If $f(x)$ represents a density of something, $\int_a^b f(x)\ dx$ repres …

Practical applications of eigenvalues/eigenvectors in computer science
PRuler is an iPhone app that lets you measure objects using a credit card and your iPhone camera. I'm told it uses a Singular Value Decomposition (which is very closely related to eigenvalues and eig …

Dynamical system defined with a non-abelian group
With $G$ higher-dimensional you don't want to think of its action as representing translations in time, but rather translations in space.

UnFlattening a 1/2 Triaxial Ellipsoid: Reconstructing a Squashed Tortoise
One thing you might try is breaking a modern tortoise shell under as close to similar conditions as possible and seeing how the dimensions change. Hopefully the proportions will be preserved.

What are the applications of functional analysis?
Much of the theory of probability can be considered as a branch of functional analysis (although some probabilists might object to this statement). For example, the Strong Law of Large Numbers can be …

An application of two 3x3 matrices identity
The equation appears rather bizarre, and I would be surprised to see a "physical meaning" in any reasonable sense of the word "physical". You might note, though, that if $A$ has nonzero eigenvalues $ …

Is there an algorithm for finding the approximate nearest neighbour from an extremely large ...
For the Manhattan distance, you can think of this an an Assignment problem: assigning a member of the $m$ to each
index of your vector $n$, where the cost for assigning $m_j$ to index $i$ is $|m_j - n …

Does COVID-19 fit into the Caspar-Klug (Quasi-Equivalence) Theory for virus architecture?
The coronavirus picture that you see everywhere does not look to me like a regular tiling. I don't know how accurate it is, though.
