A solution to divide by zero
Long story short x/0 = nullity. Nullity = "sits outside the conventional number line (stretching from negative infinity, through zero, to positive infinity)"
Does this solve anything? It just gives a new new name to what I previously knew as 'undefined'. Knowing that something equals nullity will not help anything.
In the BBC article the guy who came up with this says that this solves the divide by zero "problem". He goes on to say that "Imagine you're landing on an aeroplane and the automatic pilot's working," he suggests. "If it divides by zero and the computer stops working - you're in big trouble. If your heart pacemaker divides by zero, you're dead."
I hope to god that a computer program I have to trust with my life has a try/catch to handle a DivideByZeroException. If nullity is going to be implemented into a programming language it would do nothing. At best nullity will be handled by anything checking for a divide by zero and at worst will just create another set of bugs.
"The theory of nullity is set to make all kinds of sums possible that, previously, scientists and computers couldn't work around."
We know that the limit as x->0 of (n/x) = infinity. So how is nullity going to help?
If someone could explain to me how this could be used practically, please, please, please let me know otherwise I'm just going to give myself an aneurysm trying to figure it out.
