Splitting the Bill (fairly) is such a difficult task, that it is an accomplishment when Caltech Physicists successfully split the Bill.

Here’s an article from The Onion (Satire site) regarding this amazing accomplishment.

Maybe if they had the “Fair Bill Split” App, they wouldn’t have had such a difficult time.

Caltech Physicists Successfully Split the Bill

A. The Random Contribution Model

“Before the arrival of the check, several early bill-splitting theories were proposed, including a simple process of dividing it into eight identical fragments, the Random Contribution Model.”

If you are using the “Fair Bill Split” App, you do have the option to use the “Random Contribution Model” and split the bill evenly.

But that was rejected by the Caltech Physicists because it was unfair.

B. “Dreyfuss’s Pay For What You Ordered Algorithm”

“The team of physicists decided to test Dreyfuss’s Pay For What You Ordered Algorithm, which hypothesized that it was possible to determine what each individual owed by defining variables such as the cost of one’s entrée, the total number of beverages one consumed, one’s percentage of the sum ingestion of the component parts of the Firecracker Salmon Rolls and Buffalo Blasts, and “six bucks toward the birthday boy’s meal.”

The “Pay for What you Ordered Algorithm” is sound, but the implementation is difficult without the tools.

If those physicists had used the “Fair Bill Split” App, they would have been able to fairly allocate the purchases, and even been able to handle the birthday boy case, by not charging the birthday boy in the app, but sharing the items the birthday boy consumed among everyone else.  This is possible in the “Fair Bill Split” App.

C. “Distribution of Wine Theory”

“According to the Distribution Of Wine Theory, everyone should chip in $5 to pay for it,” gravitational-wave specialist Arjun Patel said. “But after careful observation, the theory falls apart: the bottle never moved from the other end of the table, and Tom Steinbaum was clearly seen staggering in a non-uniform circular motion whenever he got up to use the bathroom.”

So rather than charging everyone equally for the wine, by using the “Fair Bill Split” App, you could charge those who drank some wine, and not charge those who preferred water or soda instead.   That feature is there in “Fair Bill Split” App.

D. Always coming up short in the end.

“As the bill approached absolute zero, the scientists found that the closer they got to completely breaking it down, the more difficult it was to calculate.

“When we kept coming up short by $15, we thought the solution might lie in a damped simple harmonic oscillator, so we mapped complex modes of vibration in diatomic molecules, found the zero-point vibration of the n=0 ground state, studied the motion of atoms in a solid lattice, and formulated the theory of heat capacity,” Patel said. “Turns out we were on the wrong track, but it was helpful to know what definitely didn’t work.””

Had the Caltech Physicists used the “Fair Bill Split” App, they could have dealt with the coming up short problem.    In the “Fair Bill Split” App, there’s a special “So Far” field which shows the total value of items already itemized, and if it matches the subtotal, then everything has been itemized.

And to hold each person accountable, the “Fair Bill Split” App, calculates the exact amount each person should pay.  And if the amount they pay doesn’t match the total they were supposed to pay, then the group could have held that person accountable.


Caltech Physicists: You should have Split the Bill Fairly, and Easily with the “Fair Bill Split” App!



Even Caltech Physicists Successfully Split the Bill? They should have used the “Fair Bill Split” App.
