Tech Giants Tilting at Windmills

Much ado was made this week of Facebook launching a solar powered drone to bring the internet to all. It may sound like a noble goal, but beware of the physics. Facebook’s push is another example of Silicon Valley stepping outside its realm of expertise to try to do something that probably won’t work. Google […]

Flat Earth Swan Dive

There is an article out today that Stanley Kubrick’s daughter spoke out vehemently against the idea that her father, the legend himself, helped NASA fake the moon landings. She called it ‘grotesque.’ I thought it was an elegant response to an insane and stupid idea. You hear that popular culture? The moon landing was not […]

Nonlocality and Simplicity

I just read an article called “How quantum mechanics could be even weirder” in the Atlantic. The article is actually relatively good in explaining some of how quantum mechanics actually works in terms that are appropriate to laymen. Neglecting almost everything about ‘super-quantum,’ there is one particular element in this article which I feel somewhat […]

The Waste of Time That is the EmDrive

I stumbled over an article yesterday that I found again today in my newsfeed that finally causes me to be willing to spend time writing about something. The article is here. This article is about a sketchy physics topic that the popular media loves itself something fierce. Namely, the EmDrive. This device is supposed to […]

Hydrogen atom radial equation

In between the Sakurai problems, I decided to tackle a small problem I set for myself. The Sakurai quantum mechanics book is directed at about graduate student level, meaning that it explicitly overlooks problems that it deems too ‘undergraduate.’ When I started into the next problem in the chapter, which deals with the Wigner-Eckert relation, […]

A Spherical Tensor Problem

Since last I wrote about it, my continued sojourn through Sakurai has brought me back to spherical tensors, a topic I didn’t well understand when last I saw it. The problem in question is Sakurai 3.21. We will get to this problem shortly… I’ve been thinking about how best to include math on this blog. […]

How to learn Quantum Mechanics: not like this!

This particular topic never fails to get my hackles up. At breakfast this morning, I stumbled over an article about Willow Smith. This article linked to a profile on the same person. Up front, Jaden and Willow Smith have both made their feelings about school well known. They are home schooled and actively decry spending […]

“Breakthrough Starshot” or Are You Serious, Mr. Hawking?

His heart’s in the right place, I will admit that much. The “Breakthrough Starshot” project was bound to be proposed by someone eventually. Postage stamp-sized space probes riding a beam of light to Alpha Centuri, then beaming messages back to us of what they find there, all with Stephen Hawking’s stamp of approval. Explore another […]

Black Holes Don’t Just ‘Eat’…

While reading an article in Gizmodo the other day, I ended up taking umbrage with a particular comment. I’ve found in the past that it’s difficult to respond to the comments people make on these heavy traffic Gawker blogs in part because of how extraordinarily censored the comments section is and because of the pace […]

Nuclear Chicanery in ‘Batman Vs. Superman’

What a headache. I watched “Batman vs. Superman” last night and it was kind of painful. I will admit right out that I liked some parts of that movie, but quite a lot of it I did not. If you haven’t seen the movie, beware, there will be some *SPOILERS* here. The reason I’m bringing […]
