Jill Biden: Who Should, and Shouldn’t, Be Called “Doctor”?

The controversy around Jill Biden’s title, “Dr.,” could use some clarification from the dictionary

There is a controversy about whether Joe Biden’s wife should be referred to as “Doctor” Jill Biden. Isn’t “Doctor” a title for physicians only?The question is resolved easily by consulting a dictionary. Two of the definitions in the Merriam-Webster Dictionary are: 1.a person skilled or specializing in healing arts especially : one (such as a physician, dentist, or veterinarian) who holds an advanced degree and is licensed to practice 2.a person who has earned one of the highest academic degrees (such as a PhD) conferred by a university Jill Biden has a doctorate (an EdD) from the University of Delaware. Independent of one’s politics (I’m not a Biden fan), Jill Biden can be accurately referred to as Dr. Jill Biden. Read More ›

Yellow Fingers Do Not Cause Lung Cancer

Neurosurgeon Michael Egnor and computer engineer Bob Marks look at the ways Big Data can mislead us into mistaking incidental events for causes

It’s easy to explain what “information” is if we don’t think much about it. But what if we ask a student, what does your term paper weigh? How much energy does it consume? More or less matter and energy than, say, lightning striking a tree? Of course, the student will protest, “But that’s not the point! It’s my term paper.” Exactly. So information is very different from matter and energy. It means something. Realizing that information is different from matter and energy can help us understand issues like the difference between the causes of a problem (causation) and circumstances that may be associated with the problem but do not cause it (correlation). In last week’s podcast, “Robert J. Marks on Read More ›

Can a Computer Write Your Paper for You Someday Soon?

GPT-3 recently came up with a paragraph that—a pop psychologist agreed—sounded just like him

This summer the OpenAI lab, backed by $1 billion in funding from Microsoft, Google, and Facebook, released an updated version of GPT-3, a text generator that produces convincing sentences by analyzing, among other online sources, Wikipedia, countless blog posts, and thousands of digital books. According to a recent story by Cade Metz in the New York Times, one GPT-3 programmer decided to target pop psychologist Scott Barry Kaufman. Could GPT-3 really come up with a paragraph that sounded just like him? Kaufman himself (pictured) was really impressed with this one, on the subject of becoming more creative: I think creative expression is a natural byproduct of growing up in a diverse world. The more diverse the world is, the more Read More ›

To Fix Math Education, See It as a Program That Needs an Update

As a computer programmer, I’ve seen this problem in my work: The basic idea is still sound but “fixes” have made it too complex

In this series we are looking at ways that math education can be reformed. In contrast to some other math reform efforts, we are not trying to fundamentally rewrite what math education is doing but to simply admit that we can do better and see where that takes us. (See Part 1, Part 2, and Part 3.) Here in Part 4, let’s look at specific content issues that, I will argue, we could improve when we do a curriculum revision. Mathematics is an old subject. We have inherited quite a bit of mathematical thought. We must educate future generations so as to make sure that this hard-won knowledge is not lost. But one of the biggest impediments to our task Read More ›

Helping Students See How Math Benefits Them in the Long Run

To keep them motivated, we need to answer the “Why bother?” question honestly and directly

In this series we are looking at ways that math education can be reformed. In contrast to some other math reform efforts, we are not trying to fundamentally rewrite what math education is doing but to simply admit that we can do better and see where that takes us. (See Part 1 and Part 2.) Here in Part 3, we will concentrate on making the curriculum more “conscious” of what students are supposed to be learning in mathematics. One of the primary complaints students have about higher mathematics is that they don’t see where they are going to use the information later in their jobs. There are a number of ways of answering this question but first I want to Read More ›

Straight Talk About Fitting the Math Curriculum to the Student

We need to avoid pushing too much too soon, lest students come to see themselves as “bad at math” when they are just not ready for it

In this series we are looking at ways that math education can be reformed (Part 1 here). In contrast to some other math reform efforts, we are not trying to fundamentally rewrite what math education is doing but to simply admit that we can do better and see where that takes us. This article, Part 2, will concentrate on improving math education by better identifying where students are when we encounter them. Mathematics curriculum is generally developed with a goal of “fitting it all in.” That is, educators assume that people learn at a relatively fixed pace. They then pace the lessons so as to fit all of them into the curriculum in the right amount of time. However, this Read More ›

How Can We Really Fix the Way Math Is Taught?

First, we must understand why we teach math in the first place

Many people recognize that there are problems with modern mathematics curricula. However, the solutions proposed by current would-be math reformers are, I fear, worse than the cure. Some reformers want to stop having kids memorize their arithmetic facts, some want kids to just use computers to solve their problems, others think that the way we teach mathematics is racist, and still others seem to want to just greatly reduce the quantity of math education altogether. In this first part of a four-part series of short posts, I want to look at the most basic question: Why do we teach math? Earlier this month, an article by Yoree Koh in the Wall Street Journal took a look at the “Movement to Read More ›

High-Tech Suppression of China’s Mongol Region Provokes Protests

But Mongolian protesters against Chinese-dominated schools are threatened with loss of social credit, which means no jobs or loans

China is removing the Mongolian language and culture from the curriculum and textbooks in Inner Mongolia (see outline map), an autonomous region in China. In August, leaked government documents showed that language and literature, civics, and history will be taught in Mandarin rather than Mongolian in schools where Mongolian is the primary language. Additionally, the new textbooks replace stories about historic Mongolian heroes with Chinese ballads and expunge a popular folk verse that expresses pride in the Mongolian culture and language. In response, many parents in Inner Mongolia (called Southern Mongolia locally) have been keeping their children from attending school on September 1. In retaliation, state authorities threaten their jobs and social credit status: Southern Mongolia has quickly become a Read More ›

New Electronics Book Honors Citizen Scientist Forrest Mims III

Jonathan Bartlett’s dedication reflects Mims’ immense influence on electronics enthusiasts—including himself, as a boy

Forrest M. Mims III (pictured) has been an icon for many decades to two hobbyist movements: hobbyist electronics and citizen science. Anyone who used to visit Radio Shack in its heyday has probably seen and/or benefited from more than one of Mims’ books. Mims’ most prominent claim to fame was his series of Engineer’s Mini-Notebooks, small volumes that diagrammed circuits and their components and designs. Most hobbyists had a large collection of these notebooks and eventually they were collected into the book Getting Started in Electronics. Mims has also been one of the most prominent “citizen scientists.” A citizen scientist engages in science without the backing of a degree or institution, for the love of discovery. Mims is famous for Read More ›

Don’t Blame AI for the British A-Level Test Scandal

When 39 percent of the final grades assigned during COVID-19 were lower than teacher predictions, it was headline news. But what happened?

Many years ago, when I was a young assistant professor of economics, I had to endure a minor hazing ritual—serving for one year on the admissions committee for the PhD program. As a newbie, I was particularly impressed by a glowing letter of recommendation that began, “This is the best student I have had in 30 years.” The applicant’s test scores were not off-the-charts but the letter was number 1. A dean who chaired the admissions committee year after year advised me to calm down because this professor wrote a recommendation that celebrated “the best student I have had in 30 years” every year. The committee had a chuckle at my expense. I’ve now been teaching for nearly 50 years Read More ›

The Amazing Things We Can Do with Virtual and Augmented Reality

The “father of virtual reality,” Thomas Furness, talks to Robert J. Marks about his vision for the future

In a recent podcast, “Robert J. Marks and Thomas Furness on VR and AR,” Walter Bradley Center director Robert J. Marks continued his discussion with the “grandfather of virtual reality,” Thomas Furness. They focused on the cutting edge of virtual reality today. https://episodes.castos.com/mindmatters/Mind-Matters-094-Thomas-Furness.mp3 Transcript. Partial transcript: Robert J. Marks: So, Dr. Furness, we have been talking about a number of fascinating things, but there’s still some things that I’d like to talk to you about. Another one is ARToolworks. Now, AR stands for augmented reality. Thomas Furness: Now, the difference really is between the VRs generally, where you are completely immersed in a computer-generated environment. That’s all you see is the computer generation of images. AR, on the other hand, Read More ›

Five Ways COVID-19 Is Changing Education for Good

Parents, students, and teachers worldwide have been finding ways to use the internet in creative ways they would never have considered before

Recently, a Harvard prof chose to launch an attack on homeschoolers, portraying them as driven by narrow religious concerns. Given how many parents COVID-19 has forced to homeschool, the attack was, at best, poorly timed. But it usefully focused attention on the ways education needs to change in an online world.

Are Divergent Series Really an “Invention of the Devil”?

The real villain in the piece is horrendously non-specific concepts of infinity. But that can be fixed

It turns out that hyperreal numbers (i.e., infinities that obey algebraic rules) resolve many of the paradoxes that previously plagued conceptions of divergent series. It is now possible to assign specific values to divergent series.

WBC Fellow Releases introductory book on Building Scalable PHP web applications using the cloud

One new issue that the cloud creates is that programmers are more often required to be “full stack” developers,” Jonathan Bartlett explains. “Unfortunately, most programmers coming out of college have little to no system administration experience. That’s why this book is based on the ‘full stack’ concept, showing how system administration and programming relate to each other.”
