Is It Time to Replace First-Past-The-Post Voting?
Wouldn't it be more fair if being elected to a federal office required a majority rather than plurality of votes? Perhaps it's time to replace our current voting system with a ranked ballot.
Has it ever bothered you when scouring election results that so many candidates are declared winners despite the fact that most people didn't vote for them? This is a result of our first-past-the-post voting system, the subject of scorn in a recent LA Times op-ed by the mathematician Matt Parker. Most American elections (and nearly all federal elections) require that the winner be the candidate who receives the most votes rather than than the majority. This system leads to vote-splitting, as well as the quashing of any hope for third party candidates:
"This means that if you vote for a smaller party, then you are effectively throwing your vote away. Unless the party you are voting for has a shot at winning the most votes, then the reality is your vote won't count. This makes it nearly impossible for independents and new parties to get a foothold — and results in the two-party system that has dominated U.S. politics for decades."
Worst of all is the chance of something called "the spoiler effect," which causes the aforementioned split-votes. Let's assume, for example, that Candidates A and B are the frontrunners in a major election. Also running is Candidate C, who is more similar to Candidate A and very different from Candidate B. Voters whose beliefs fall in line with Candidates A and C would never support Candidate B. Yet those voters have to decide whom to vote for out of two relatively similar candidates. On election day, here are the results:
Candidate A: 35%
Candidate B: 40%
Candidate C: 25%
Candidate B would therefore be declared the winner because he/she earned more votes than anyone else. But not only did 60% of voters not support Candidate B, he/she probably wouldn't have been many of their second choice.
The great Youtube explainer-of-all-things CGP Grey has a terrific video further illustrating the faults of first-past-the-post voting:
Both CGP Grey and Matt Parker advocate for the adoption of a ranked ballot (or "alternative vote"). This system would allow voters to rank candidates by preference. If no candidate has a majority once votes are counted, an instant run-off begins where votes from the candidate who finished last are reallocated based on those voters' second choices. This process continues until one candidate has earned a majority.
Let's go back to our example above to demonstrate how this ballot works. Remember that our voting results had Candidate B winning a plurality with Candidates A & C splitting. Under first-past-the-post, Candidate B is the victor. On a ranked ballot, Candidate B's inability to achieve a majority means that Candidate C (who finished last) has his/her votes reallocated to the voters' second choice. If everyone who voted Candidate C put Candidate A as their back-up, the election results would look like this:
Candidate A: 60%
Candidate B: 40%
Candidate C: Elim.
Not only do these election results better reflect voters' preferences, this system allows for supporters of the third party candidate to have their vote count for something. Again, CGP Grey finds a way to explain the ranked ballot in an entertaining, informative fashion:
Knowing the degree to which crippling inertia affects our political system, it's unlikely a major change in how we elect candidates could occur overnight. But a well-organized campaign bent on informing the electorate about the faults of first-past-the-post would be a good start.

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
It turns out, that tattoo ink can travel throughout your body and settle in lymph nodes.
In the slightly macabre experiment to find out where tattoo ink travels to in the body, French and German researchers recently used synchrotron X-ray fluorescence in four "inked" human cadavers — as well as one without. The results of their 2017 study? Some of the tattoo ink apparently settled in lymph nodes.

As the authors explain in the study — they hail from Ludwig Maximilian University of Munich, the European Synchrotron Radiation Facility, and the German Federal Institute for Risk Assessment — it would have been unethical to test this on live animals since those creatures would not be able to give permission to be tattooed.
Because of the prevalence of tattoos these days, the researchers wanted to find out if the ink could be harmful in some way.
"The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body," they write.
It works like this: Since lymph nodes filter lymph, which is the fluid that carries white blood cells throughout the body in an effort to fight infections that are encountered, that is where some of the ink particles collect.

Titanium dioxide appears to be the thing that travels. It's a white tattoo ink pigment that's mixed with other colors all the time to control shades.
The study's authors will keep working on this in the meantime.
“In future experiments we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible bio-distribution of tattoo ink ingredients throughout the body. The outcome of these investigations not only will be helpful in the assessment of the health risks associated with tattooing but also in the judgment of other exposures such as, e.g., the entrance of TiO2 nanoparticles present in cosmetics at the site of damaged skin."
