Lectures for a New Year: A Physics Classic from 1960

In 1960, University of Toronto physics professors Patterson Hume and Donald Ivey produced a half-hour educational film explaining basic principles of physics. They called it Frames of Reference, and used the opportunity to make the seemingly-boring topic of physics education actually pretty fun (or at least as fun as an educational film from 1960 featuring dudes in suits could be). Using visual gags and a series of engaging experiments featuring themselves and hockey pucks, the professors explained how objects move, how we perceive their motion, and why those things matter. If you enjoy nothing else about this physics lecture, just check out their staging -- they had to build a complex set and camera rig to film this thing! This is one of several engaging films made by the seminal Physical Science Study Committee.

Topics: people upside-down, movement, velocity, observation, hockey pucks, force, unbalanced forces, and of course frames of reference.

For: anyone who wants to learn some basic physics, or who enjoys old educational films. There's also some inherent interest here for educators -- this film has been used in classrooms for fifty years to explain physics, and is a stellar example of how education on heady topics (like physics) doesn't have to be boring.

Viewing notes: Audio doesn't start until about 30 seconds in. Also, if the embedded video below doesn't work for you, try YouTube: part one, two, three. The YouTube videos are lower-quality, but work on more devices. A high-quality download is available from Archive.org.

Further Reading

Ivey and Hume also worked on the classic CBC TV series The Nature of Things. You can see more recent incarnations of the series from the CBC. The pair also wrote a book about physics (in two volumes) on the topic, though it's a little tricky to buy copies these days -- each volume goes for more than a hundred bucks on Amazon! Check for it in your local library instead (I found a library copy just ten miles away!).

Transcript

I haven't been able to find a transcript of this talk. The only option I've found is to enable YouTube's automated captioning system, which frankly doesn't work very well with this fuzzy audio.  UPDATE:  here is a transcript, though you need access to the American Journal of Physics (usually best done achieved via a library).

Want to Become a Billionaire? Study Engineering

If you want to get rich—really, really rich—chances are, you should get yourself an engineering degree. As The Telegraph reports, a new analysis from the UK firm Aaron Wallis Sales Recruitment finds that more of the top 100 richest people in the world (according to Forbes) studied engineering than any other major.

The survey found that 75 of the 100 richest people in the world got some kind of four-year degree (though others, like Bill Gates and Mark Zuckerberg, attended a university but dropped out before graduation). Out of those who graduated, 22 of those billionaires received engineering degrees, 16 received business degrees, and 11 received finance degrees.

However, the survey doesn't seem to distinguish between the wide range of studies that fall under the "engineering" umbrella. Building a bridge, after all, is a little different than electrical engineering or computing. Four of those 100 individuals studied computer science, but the company behind the survey cites Amazon's Jeff Bezos (who got a bachelor's degree in electrical engineering and computer science from Princeton) and Google's Larry Page (who studied computer engineering at the University of Michigan and computer science at Stanford) as engineers, not computer scientists, so the list might be a little misleading on that front. (And we're pretty sure Bezos wouldn't be quite so rich if he had stuck just to electrical engineering.)

Aaron Wallis Sales Recruitment is, obviously, a sales-focused company, so there's a sales-related angle to the survey. It found that for people who started out working at an organization they didn't found (as opposed to immediately starting their own company, a la Zuckerberg with Facebook), the most common first job was as a salesperson, followed by a stock trader. Investor George Soros was a traveling salesman for a toy and gift company, and Michael Dell sold newspaper subscriptions in high school before going on to found Dell. (Dell also worked as a maitre d’ in a Chinese restaurant.)

All these findings come with some caveats, naturally, so don't go out and change your major—or head back to college—just yet. Right now, Silicon Valley has created a high demand for engineers, and many of the world's richest people, including Bezos and Page, earned their money through the tech boom. It's plausible that in the future, a different kind of boom will make a different kind of background just as lucrative. 

But maybe don't hold your breath waiting for the kind of industry boom that makes creative writing the most valuable major of them all. You can be fairly certain that becoming an engineer will be lucrative for a while.

Dedicated Middle School Teacher Transforms His Classroom Into Hogwarts

Kyle Ely

It would be hard to dread back-to-school season with Kyle Ely as your teacher. As ABC News reports, the instructor brought a piece of Hogwarts to Evergreen Middle School in Hillsboro, Oregon by plastering his classroom with Harry Potter-themed decor.

The journey into the school's makeshift wizarding world started at his door, which was decorated with red brick wall paper and a "Platform 9 3/4" sign above the entrance. Inside, students found a convincing Hogwarts classroom complete with floating candles, a sorting hat, owl statues, and house crests. He even managed to recreate the starry night sky effect of the school’s Great Hall by covering the ceiling with black garbage bags and splattering them with white paint.

The whole project cost the teacher around $300 to $400 and took him 70 hours to build. As a long-time Harry Potter fan, he said that being able to share his love of the book series with his students made it all pay off it. He wrote in a Facebook post, "Seeing their faces light up made all the time and effort put into this totally worth it."

Though wildly creative, the Hogwarts-themed classroom at Evergreen Middle School isn't the first of its kind. Back in 2015, a middle school teacher in Oklahoma City outfitted her classroom with a potions station and a stuffed version of Fluffy to make the new school year a little more magical. Here are some more unique classroom themes teachers have used to transport their kids without leaving school.
