A no-math guide to quantum mechanics from Ars Technica

A “no math” (but seven-part) guide to modern quantum mechanics from Ars Technica


This looks good. I am going to use it in a class tomorrow.

I opened this in a tab this morning, just getting home, hoping to read it soon. Glad to hear it's not going to be a waste of time. 🙂

Was the content actually there before you looked at the open tab?

One day Schrodinger gets pulled over. "Do you know how fast you were going?" the officer asked him. "No idea, but I know exactly where I am!" he replied.​​​​​​

Nice read. This should help a lot of folks who are interested in physics but get bogged down in the detail mathematics. Most science seems to b presented on a highly mathematical level, or dumbed down to the point its useless. If this guy can present the concepts without all the fine technical details, and get people to read it, it'll go a long way to improving science literacy.

Next up in physics: He presented the connection between classical and quantum physics, I wonder if he'll introduce the third rail of physics,the BIG stuff out there in the universe, which is now coming to light. Best example is gravity waves discovery that was predicted by Einstein and recently proven to be out there (its a space/time distortion thing that's been in sci-fi stories for eons).

Also looking forward to reading.

For those interested in quantum computing, I recommend prof Scott Aaronson's blog, book, and magazine articles and interviews in many venues. He specializes in smacking down popular myths and misconceptions about quantum computing, the most persistent of which is 'quantum computers/algorithms try all the possibilities at the same time'.

This explanation of Shor's polynomial-time quantum-computer algorithm for factoring large semiprimes is praised by Peter Shor himself as "the best job of explaining quantum computing to the man on the street that I’ve seen." I plan to adapt it for use with high school seniors in a couple months.

I always thought quantum computing meant you never know the output from an algorithm until you execute it. It's pretty likely that 1+1=2 at least most of the time.

I used a similar demo years ago to illustrate the idea to a cousin's kid who had ADHD and other problems but was intensely curious about everything.

Unfortunately I marred the lesson by describing the laser as a "laser gun" rather than beam projector or other neutral term. He became fixated on the word "gun" and from there the entire discussion was about death rays and science fiction. But, hey, it was a start. Maybe he revisited the lesson later.
