Achilles and the Tortoise

The Paradox:

In this thought experiment, Achilles, a swift warrior, is racing against a slow-moving tortoise. To make it fair, the tortoise is given a head start. The paradox argues that Achilles can never overtake the tortoise, no matter how fast he runs.


Here’s how the paradox is laid out:

  1. Initial Position: The tortoise starts ahead of Achilles.
  2. Achilles Moves to the Tortoise's Initial Position: By the time Achilles reaches the point where the tortoise started, the tortoise has moved forward a small distance.
  3. Achilles Moves to the Tortoise's New Position: Achilles then moves to the new position of the tortoise, but by the time he gets there, the tortoise has moved even further ahead.
  4. Repetition: This process continues indefinitely, with Achilles always reaching where the tortoise was, but the tortoise always being a little bit ahead.

The paradox suggests that Achilles will never be able to overtake the tortoise because there are infinitely many points he must reach where the tortoise was before he can catch up.

Resolving the Paradox:

If you sum the infinite series of times Achilles takes to cover these increasingly smaller distances, the sum converges to a finite value. This means that, mathematically, Achilles will indeed overtake the tortoise after a finite amount of time, despite the infinite steps involved in the paradox.

A mindfulness message:

The Achilles paradox offers us a profound lens through which to view time, suggesting that within every fleeting moment lies an infinite series of experiences.

 FIVE THOUSANDTHS of a second the margin Noah Lyles won the 100m Olympic Final - the difference between triumph and defeat.

This emphasises the incredible value of even the smallest moments in our lives.  They are the building blocks of our experiences, shaping our journeys in ways we might not always notice.

When we say life is short, it's easy to overlook the infinite number of moments that fill even a single second. The Achilles paradox reminds us that within the span of what seems like a brief life, there are endless opportunities, choices, and experiences—each as valuable as the last.

So, rather than seeing life as fleeting, we can embrace the idea that every moment, no matter how tiny or "insignificant," is infinite in its potential. Just like in that Olympic race, where a fraction of a second made all the difference, every moment in our lives holds the power to shape our future. 

Life may be finite in years, but it's infinite in moments—each one a precious opportunity to live fully and meaningfully.

Deconstructing WDL and O/U 2.5 goals odds.

Input odds below (in decimal): Home Odds: Draw Odds: Away odds: Over 2.5 Odds: Calculate Params See also Elo Reverse Calculator . Dixon Coles Dixon Coles is a method of generating probabilities on football matches.  It is related to Poisson but adds a correlation for low scores.  It seems to be one of the most accurate public methods.  It requires three parameters lambda, mu and rho.  rho describes how related low scores are.  lambda and mu represent the average goals the home and away team are expected to score. In this calculator I have fixed rho = -0.13 (more info here  and here ) and I simply do a brute force search varying lambda and mu to find the values that has the lowest error from the Win Draw Lose and Over 2.5 odds entered.  I use the WDL odds and Over/Under odds as they are the most liquid betting markets and you can usually read a very accurate estimate for these off oddschecker or the exchange.   The soluti...

Donations now accepted If you have enjoyed using this extension and want to show your appreciation then click "Buy me a coffee" below, otherwise continue further down to read about our features! This started off as just a personal project.  I got full value from the effort that I put in already.   The effort included a few days coding initially and a day or two here or there to fix and add features, perhaps a full working week but fragmented all over the place.  In total it is now about 150 lines of code.   The reward was learning some javascript, learning about chrome extensions, earning some cred on twitter, and getting to connect with different people.  And of course I am actively using it and can identify potential betting opportunities myself. However surprisingly many have found it useful and some have asked for a way to say thanks.  So here it is. Feature Request (01 February 2024) - only available to manually install due to gambling exetn...

Elo Reverse Calculator

Input odds below (in decimal): Home Odds: Draw Odds: Away odds: Calculate Params Elo Elo is simply a way of rating teams.  The ratings can be used to compare teams and generate probabilities for head to heads.  The probability one team will beat another is just a function of the difference in their rating. p = 1/(1+10^(-diff/400))  The tweet further below from ClubElo introduces another parameter r to take account of draws. Elo: The Hard Way The process is better described on eloratings.net  and clubelo.com .  If you visit these sites you can see it is quite complex.  Basically you initialise all teams to 1000 points for example.  Then you need a history of results and update each teams ratings depending if they win, lose or draw.  There are nuances to worry about, home field advantage, big wins, inter-league adjustments, k-factor weightings, etc. Elo: The Easy Way Say someone has already rated the teams, and also they have tak...
