I do not know of such thing, but let me know if you come across this mystery.

Yes there are a few . One is The electrical power equation.
Watts = volt x amperes
Watts indicate power.
Amperes is Energy measured in coulombs divided by seconds.
So energy divided by time is equal to power.
Power is defined as force x velocity.
So Volt represents a force.
If you plug these definitions into the equation for Watts it does not dimensionally agree.The reason why this happens? well this is what makes the cooky crumble.

you're able to desire to settle for particular definitions of time in case you want to debate with others, on the grounds that without straight forward definition, you have no longer any base for dialogue. Time isn't a actual length yet is seen because of the fact the 4th length. there are probable different dimensions additionally. The dilation of time at relativistic velocities is what you're pertaining to. The working of clock, the turning out to be previous of issues, all decelerate. So, how can you degree the time. Pl. examine the particular thought of relativity to get a greater valuable understand-how of this occasion. superb desires.

There are some empirical correlations where dimensions are not meaningful. Imagine if you measure number of fish in the ocean as a function of depth. 20 m should have more fish than 10 m.

there cannot be a equation that is logical and dimensionally not
matching
some previous answer said that energy is coulomb per sec
and volt is a force
please check your basics current = coulomb/sec not energy
and watt= volt x current is dimensionally perfect
watt = joule /sec
current = coulomb/sec
volt= joule/coulomb
hence LHS=RHS
if you dont have dimensional matching it is equivalent to something like cows= tables or fruits= dogs totally meaningless!!

well, more or less the string theories goes from 5 to 14 dimensions.
But are they correct ? From the mathematical point of view yes, but what the hell they describe ? a number of dimensions that nobody had even developed an experiment to detect them.
