Mathematics

The most crucial to happy gambling generally (apart from being prepared for losing, since you create a losing copy of yourself with certainty) is your Happy-Enough-Ceiling, where if you reach it, you leave with your winnings. The trivial example is entering the casino with three dollars and playing Martingale roulette, leaving as soon as four dollars are won – the Many Worlds/Minds (MW/M) tree then looks like this:

 

Mental Health Warning: Many World/Mind (MW/M) descriptions may aggravate mental conditions; suicidal ideation has been recognized as a pitfall along the path of Zen-like wisdoms by a wide range of authors as diverse as to include Carlos Castaneda. (Suggesting potential public health benefits of MW/M ethics, I suggest careful adoption in select high school trials and long term monitoring of suicide rates and depression [unpublished].)

Trevor Hastie, the Stanford University guru on Statistical Learning (he coined the term together with his colleagues Tibshirani and Friedman) is in Padova this week, where he is giving a short course on his pet topic and a seminar. I am happy to report this as this was partly made possible by the European Union-funded network of which I am the project coordinator, AMVA4NewPhysics. But most of the merit is of Prof. Giovanna Menardi, PI of the Padova node of the network, who organized it... And of course I am happy because I am learning from his insightful lectures!

(Above, prof. Menardi introduces the lectures).

A few days ago I discussed the coin toss game ‘triple or bust‘. The game is between Alice and Bob. Alice start the game by writing a $ 1.00 IOU to Bob. Alice then makes at least six subsequent tosses with a fair coin. On each ‘heads’ Alice triples the IOU amount. On ‘tails’ she sets the IOU to zero.

Today I have a decision problem for you.

Lovely Lisa Long Leg and Heil Hitler Screaming Nazi once again visit the Stupid Donald Trump Follower’s office in the mathematics department:

Lovely Liberal Lisa: Heil Trump!

Stupid Donald Trump Follower: Well, that’s better than what we had before, but I am still not convinced such does anybody any favors.

Two days ago, before returning from Israel, my fiancee Kalliopi and I had a very nice dinner in a kosher restaurant near Rehovot in the company of Eilam Gross, Zohar Komargodski, and Zohar's wife Olga. 
The name of Eilam should be familiar to regulars of this blog as he wrote a couple of guest posts here, in similar occasions (in the first case it was a few before the Higgs discovery was announced, when the signal was intriguing but not yet decisive; and in the second case it was about the 750 GeV resonance, which unfortunately did not concretize into a discovery). As for Zohar, he is a brilliant theorist working in applications of quantum field theory. He is young but already won several awards, among them the prestigious New Horizons in Physics prize.
A false history of science was used to initiate colonial education, in support of colonialism. This false history persists. In a recent article about decolonizing mathematics, for instance, Professor Karen Brodie asserts that, “Much, though certainly not all, of mathematics was created by dead white men.”

This is not true.

During the Pamplona, Spain, "Running of the Bulls" you won't need all of the ambulances that are placed along the route, so how do event organizers know where they should be? Statistics helps know. 

Experts have studied the bull runs of the last six years (a total of 48 races) in order to identify the risks that exist. As you might anticipate, absent an extraordinary event, like a terrorist attack or alien invasion, the risk to one set, the runners and the bulls, are the bulls themselves, the runners and the route. Runners may incur slight injuries such a falls, scratches or breakages, or even being gored. The bulls can suffer physical consequences such as broken horns or hooves. 

UK bookmakers will undoubtedly benefit from three of the home nations (England, Northern Ireland and Wales) making it to the Euro 2016 finals. But if you want to bet with your head, rather than your heart, where should you put your money?

You might be surprised that there is sometimes a way that you can bet and be guaranteed to win. If you can find the right set of odds and put the right amount of money on each outcome, you will win back more than the total amount you bet, no matter what happens. For example, with the following odds, if you bet a total of £73 across the different teams left in the tournament, you’d be guaranteed to have a final balance of at least £99.
