Over a decade, a few names kept popping up as winners of all kinds of games. The most prolific of these winners, according to the lottery data, was a man who claimed an incredible 252 prizes during six years, for a total take of $719,000.

Drawing on 20 years of data, he has set his computer to work on this question: If you had invested according to this scheme in the past, which portfolio would have been the best? His computer assembled thousands of such simulated portfolios and calculated for each one an industry-standard measure of return on risk. Out of this gargantuan calculation, your advisor has chosen the optimal portfolio. After briefly reminding you of the oft-repeated slogan that "past performance is not an indicator of future results", the advisor enthusiastically recommends the portfolio, noting that it is based on sound mathematical methods. Should you invest?

A true model for a particular problem can rarely be defined with certainty. The most we can do to mitigate error is to quantify the uncertainty in the model.

For centuries it has been used to describe the forces of nature, from planetary motion to fluid dynamics. It helped unlock the secrets of DNA and unleashed the Digital Revolution. Today, in the age of high-resolution detectors and international research collaborations, math again has the potential to transform science and accelerate discovery. But this work will require state-of-the-art mathematics, carefully crafted in inventive new ways.

But what you may not have realized is the search for the rarest of them is an international one, with a local effort led in an unconventional way by two Indiana State University professors.

And, to the chagrin of loyal Mets fan Bukiet, New York's National League club looks to be in store for a disappointing year. Bukiet, who developed a mathematical model for calculating expected MLB win totals that was published in Operations Research, forecasts a mere 68 wins and a last-place finish for the Metropolitans.

A paper published last November in the SIAM Journal on Imaging Science attempts to overcome these photography woes.

At the time, he never thought that his research on the dynamics of liquids using statistical physics would one day lead to an algorithm that ranks sports teams. Yet now, more than a decade later, he's running a website devoted to sports analytics based on statistical physics that works much in the same way as Google's PageRank algorithm works for ranking websites.

In a paper they've uploaded to the preprint server arXiv, the two describe how they set a computer program to proving a small part of what's known as "Erdős discrepancy problem"—the proof produced a data file that was 13-gigabytes in size—far too large for any human to check, leading to questions as to whether the proof can be taken as a real proof.

The payoff would be the ability to target the specific affected cancerous area, rather than the entire body as in the current chemotherapy approach.
