Computers Scan Restaurant Reviews for Clues of Unhealthy Food

April 23, 2018

If someone gets sick after eating suspected food at a restaurant, it is more likely that they will post it on social media, than report it to the local Health Department.  Computers developed at Columbia University scan restaurant reviews for words that might indicate a problem with spoiled food.  After finding multiple reports online, Health Department inspectors can be sent to investigate.

“Tainted food and drink sicken some 48 million people in the United States each year. That’s according to the Centers for Disease Control and Prevention. Nearly seven in every 10 of those incidents came after dining in restaurants.”

Investment Decisions – Brains Vs. Computers; Which is Better?

June 13, 2017

The two points of view represented below are both well reasoned, conflicting, and cogent, but can they both be right?  The experts currently disagree, but maybe one day the question will be answered definitively.  For now, it makes for an interesting debate, and only time will tell who is right.  Today’s answer may not be tomorrow’s answer.

A key question is how much data does one need in order to make smart investment decisions.  Those who believe best decisions come from analyzing tons of data lean towards computer algorithms, while those who think smart evaluations don’t require looking at every piece of data lean toward human understanding and interpretation.

The term “quants,” refers to those quantitative analysts who crunch the number and are more reliant on computers and algorithms.

The Nobel Prize in Physics Awarded

October 6, 2016

The following two paragraphs are quotes from a fascinating article about how 3 physicists “playing” with math stumbled upon a remarkable and practical finding.  The link to the whole article follows the quotes.

“A trio of British-born researchers working in the U.S. won the Nobel Prize in physics for what one of them called a curious mathematical “toy” that to his surprise revolutionized the study of exotic matter suitable for quantum computers, new superconductors, and advanced designer materials.”

” “At the time, I thought it was of scientific interest and mathematical interest, but I didn’t think it would ever find a particular realization,” said Princeton University physicist F. Duncan M. Haldane, who shared the award for theoretical experiments he had conducted in the 1980s. “I basically stumbled on this playing with mathematics.” ”
