What do you get when mixing
Aluminium, Neon, Nitrogen, Sulfur, Titanium, Vanadium,
and two math ingredients
$\lim_{n\to\infty}(1+\dfrac{1}{n})^n $ and (degree,?,seconds)
and
don't ask why.
This mix exists only today! Find the mix.
The mix is
VALENTINE'S, which is today!
The chemical elements and mathematical clues
all resolve to single letters/symbols or bigrams: AL, NE, N, S, TI, V for the elements; E and ' (as in minute) for the math.
Then, we “mix” these ingredients by
anagramming them to form a word or phrase that would make thematic sense. Of all the possible anagrams, VALENTINE'S is most appropriate here.
My answer is
Valentines X
The chemical symbols:
Al Aluminium
Ne Neon
N Nitrogen
S Sulfur
Ti Titanium
V Vanadium
and the mathematical symbols $e$ and $x$
make an anagram of alnenstivex
The mathematical expression has the value $1$ and the missing word is minute
so perhaps that part means
for one minute ?
love you - only today!
