The Age of the Algorithm

One study from 2018 found that Major League Baseball umpires blow about 14 calls every game. That’s 34,000 bad calls every year. And it makes a difference. A blown strike call can decide a win or a loss, a championship or six months at home, wondering what could have been. And wh ... Show More

Hidden from view, complex to understand and often controversial, algorithms are at the heart of computer coding that underpins modern society. Every time we search the internet, every time we pay by credit card, even the romantic partners suggested to us by online dating sites – ... Show More

Can algorithms help writers think more clearly and create innovative work ? On this week's 'Algorithm Verb' Ian McMillan is joined by Helen Arney, who performs a brand new love-song (written for the programme) using search engine algorithms, by Eugenia Cheng, a mathematician and ... Show More

At its simplest, an algorithm is a sequence of step-by-step instructions designed to give a result. They are the building blocks of every computer program and are there to ensure every digital device gives the right results on request. For example, when we type a search query int ... Show More

Mathematics as a subject is distinctive in its symbolic abstraction and its potential for logical and computational rigor. But mathematicians tend to impute other qualities to our subject that set it apart, such as impartiality, universality, and elegance. Far from incidental, th ... Show More

Artificial intelligence is letting us make predictive algorithms that translate languages and spot diseases as well or better than humans. But these systems are also being used to make decisions about hiring and criminal sentencing. Do computers trained on vast datasets of human ... Show More

The data science and artificial intelligence community has made amazing strides in the past few years to algorithmically automate portions of the healthcare process. This episode looks at two computer vision algorithms, one that diagnoses diabetic retinopathy and another that cla ... Show More

In 1997, Garry Kasparov, widely regarded as the world's greatest chess player, was defeated by Deep Blue, a computer. But how much did that reveal about the 'brainpower' of machines? Tim Harford explains by delving into the history of algorithms. They've been used by mathematicia ... Show More

Computers are ranking the way people look—and the results are influencing the things we do, the posts we see, and the way we think. Ideas about what constitutes “beauty” are complex, subjective, and by no means limited to physical appearances. Elusive though it is, everyone wants ... Show More

In 2015 an MIT Researcher set out to build a mirror that would augment their face to look like those of their idols. The execution of this went well, until it came to testing. When the researcher came to use the mirror, no face was detected. The researcher was not detected in the ... Show More
