What is i 4?
Ah yes, the big question on everyone’s mind. What in tarnation is i 4? Is it a new type of Apple product? A secret government code that only the chosen few know about? Or maybe it’s just some bizarre mathematical formula that nobody really understands.
Well folks, I’m here to tell you that i 4 is actually none of those things (sorry to disappoint). In fact, i 4 is something far more complex and exciting than any of us could have ever imagined. So buckle up, grab a snack (or two) and let me take you on a wild ride through the wonderful world of i 4!
The Basics
First things first – what exactly is i 4? At its core, i 4 is simply an extension of the concept of imaginary numbers. For all you math whizzes out there (weird flex but ok), imaginary numbers are essentially square roots of negative numbers that can’t be expressed as real numbers.
i^2 = -1
But where does “i” come from in the first place? Well friends (and enemies), “i” stands for imaginary unit, which represents √-1 . Now back to our regularly scheduled programming…
If we take this idea one step further and raise “i” to the fourth power:
(i)^4 = (i x i x i x i) = (-1) x (-1) =
and we get…drumroll please…good ol’ regular one! Crazy stuff right?
Applications in Engineering
Now I know some (most) people out there may think “who cares?”, but hear me out. This concept has MASSIVE implications in engineering when working with alternating current circuits (AC circuits for our fancy science folk) where voltage changes continuously over time.
Using complex algebraic equations involving i 4 and other imaginary numbers, engineers can predict voltage and current in these circuits with astounding accuracy (and make your electronics work properly). So the next time you’re scrolling through Instagram on your phone or jamming out to Spotify (or both let’s face it) – thank the wonderful world of i 4.
Bigger Picture
But why stop at just engineering? The concept of imaginary numbers has far reaching impact across a vast array of fields. Everything from quantum mechanics (cue every physics major rolling their eyes) to finance (surprise) utilizes this fundamental mathematical principle.
For example, in quantum mechanics the famous Schrödinger equation uses complex numbers that involve “i” to describe wave functions. And in finance (especially fancy economics people alert), complex numbers are often used when analyzing data from financial markets to model volatility (very important for understanding how money works basically).
So whether we realize it or not, our daily lives may be more intertwined with i 4 than we think. Who knew math could be so cool?
Some Fun Facts About Imaginary Numbers
In order to truly appreciate the complexity and wonder behind i 4 (which I’m sure you all do by now naturally…right?) here are some fun factoids about imaginary numbers:
- The idea of an “imaginary unit” was first introduced by mathematician Rafael Bombelli in the sixteenth century (history lesson bonus points for those taking notes)
- Imaginary numbers were actually met with skepticism by many big name mathematicians including Leibniz and Descartes (kinda like Pluto not being a planet drama)
- It wasn’t until over a hundred years later that Swiss mathematician Euler popularized the use of “i,” which is still widely used today
- Even though imaginary numbers may seem abstract and confounding at times, they are fundamental components of modern day technology and scientific advancement…pretty cool for something imaginary huh?
End of the Line
Whew, we made it folks. Thanks for sticking with me through this wild journey of i 4 and all things imaginary.
So what can we take away from all this? Well, maybe that math isn’t so scary after all (although I’m not going to try solving any complex equations anytime soon). Or maybe it’s just a reminder that some concepts may seem daunting or confusing at first glance, but have huge impact in our daily lives. Either way, I hope you’ve learned something new today (or were thoroughly entertained).
Until next time friends (& foes).
