Argonne labs and the Hunt for Red October

Argonne labs and the Hunt for Red October

One of my favorite movies was The Hunt for Red October. In it, Sean Connery plays a Soviet sub commander in control of a nearly silent intercontinental ballistic submarine. Its silence comes from a hypothetical magnetohydrodynamic drive that had no propellers. But this was all fiction, wasn’t it?

When I was in high school, our science team took a trip to Fermi lab and Argonne National Laboratories up near Chicago. I was captivated. I still remember the discussion on subatomic particles by the Fermi lab speaker and seeing some of the devices such as the Tevatron. I still remember him talking about plans for an even larger collider being planned in Europe (hint, they built it).

At Argonne labs, we took another tour. At one point, we went into one of the large warehouse labs and there was a giant circular machine. The guide told us it was, in fact, an experimental magnetohydrodynamic drive. He shared some interesting anecdotes about the device. It turns out, the principles were sound. By creating a gigantic magnetic field one could indeed introduce thrust from salt-water passed through the center of it. If you want to make one, it is not complex and there are even YouTube videos demonstrating small devices.

The biggest problem? It wasn’t very fast, and you needed a GIANT magnetic field. It also didn’t work in fresh water and had a variety of other limitations and caveats.

The Japanese experimented with the technology as well and there were numerous prototypes developed. They also ran into the same problems but it did advance the field a bit by using smaller and more powerful superconducting magnetic systems to introduce the field. It works fairly well on a small scale, but pushing something as large as a transport ship or ballistic missile submarine was untenable. Not much has happened since those days as the physics of the system simply don’t work out – though China recently announced their experiments.

Still, it was absolutely fascinating to see something that was on movies and hinted at as secret technology in person. I think it was a big part of what got me interested in science and led me to computer science years later.

There has also a lot of suggestions that The Hunt for Red October book, publish from a nobody salesman via the Navy Institute Press, contained then-classified secrets, and happened at the same time of several strange submarine incidents was actually a ploy to signal certain messages to the Soviet Union. Since Tom Clancy recently died, we may never know for sure. But it wouldn’t be the first time this has happened.

Everest Helicoptering

Everest Helicoptering

One of the things many young adventurers love to do is travel to Nepal and hike some of the amazing trails through Himalayan mountains. The popularity of these multi-day to multi-week hikes has lead to a more crowded and less authentic experiences of previous travelers, but you just can’t beat something like a week or two on the Annapurna Circuit.

You can also hike to Mt Everest base camp as well as often take a short trip up the nearby facing peak Kala Patthar to see both Everest and Lhotse (if the weather cooperates).

A third option is to go by helicopter. Sam Chui shows us that for about $1200, you can take an amazing few hour helicopter trip through these destintions:

1. Kathmandu (4,390 ft / 1,338m) 2. Lukla (9,380 ft / 2,860m) 3. Namche Bazar (11,290 ft / 3,440m) 4. Syangboche (12,402 ft / 3,780m) 5. Khumbu Icefall (17,999 ft / 5,486m) 6. Mt Everest (29,031 ft / 8,849m) 7. Kala Patthar (18,519 ft / 5,644m) 8. Cho La Pass (17,782 ft / 5,420 m) 9. Gokyo Ri (17,575 ft / 5,357m) 11. Hotel Everest View (12,729ft / 3,880m) 13. Lukla (9,380 ft / 2,860m) 14. Kathmandu (4,390 ft / 1,338m)

He recommends going in April or October when the weather is at its clearest and not so cold. He flies via Manang Air – who have a variety of packages.

Iceland Itinerary

Iceland Itinerary

Allan Su has traveled Iceland several times and gives a really great itinerary of how to spend 2 weeks (travel during June-Sept) visiting the amazing outdoor locations of Iceland. He hits both the famous/well traveled locations as well as lesser known but amazing attractions. He also gives a great set of advice on a number of handy resources from rentals to checking weather/travel conditions.

Too much light

Too much light

I saw the show Too Much Light Makes the Baby Go Blind in the early 2000’s in Chicago. In their show, you see 30 original plays in 60 minutes. Things start out unusual right off the bat. Audience members line up for admission and roll a die for their admission price. Once you get briefed on the ground rules, you shout out the numbers of the two-minute plays they want to see performed next. Each play is written and acted by the ensemble and what you see constantly evolves as they cast creates new plays all the time. If you’d like to read some of them, a set of them is available on Playscripts to read/license.

It was the longest running show in Chicago theater history and is now also in New York and San Francisco. While a great premise, lots of energy, and the show I attended a lot of fun – you should expect to get plays around very particular and homogenous political/social viewpoints by a cast of mostly very young actors.

Infinite Wrench

Behind the scenes, however, there were problems almost immediately (definitely worth a read). The show idea was founded by Greg Allen and rocketed to local popularity. As it grew, he moved to a new venue and formed an ensemble to perform it every day. Sadly, it turned into a classic example of a idealistic collectivist vision that quickly degraded into relatively predictable battles of egos, control, and ugliness.

“He started this company with this very egalitarian concept,” said former ensemble member Andy Bayiates. “We won’t have any leaders and we’ll have a collective and we’ll do everything together. But his actions never matched up with that vision.”

The conflicts started almost immediately. There were conflicts on expanding the franchise that might put ensemble pay structures at risk, views that Allen was cashing in on the licensing and work of the individual ensemble members, he often ‘forgot’ the lines to 2 minute plays he didn’t like, wished to retain final right of refusal on direction and which individual plays were made, personal clashes, and other issues. The ensemble documented the problems with Allen and in Dec. 2011 came the final disagreement over a play featured in a “best of” anniversary show that lead to Allen’s suspension from the company.

In 2016, Greg Allen revoked the Chicago branch’s rights to the play after “considerable artistic differences and irreconcilable personal conflicts”. The Chicago branch now performs an almost identical show called the Infinite Wrench.

Collectivism is hard

This is sad but shouldn’t be a surprise. The rise and fall of the Soviet Union took only 68 years but killed millions of its own citizens in political gulags, poor management, and ethnic cleansings. China’s politically brutal regime also killed millions, lasted barely longer, led to decades of stagnant development, and has largely abandoned communism for heavily controlled capitalism. The Communist revolution of Laos gave us the killing fields of Pol Pot. North Korea stands out with growing humanitarian crises, lack of development, nuclear blustering, and rule by dictatorship. Steve Jobs who lived at and was inspired by the farm commune All One Farm (owned by Robert Friedland) but by many accounts of those that worked for him often painted him as a dictator. Sadly, egalitarian societies in the 20th century have almost universally turned into the most brutal regimes in all of human history.

There is only one form of living collectivism that has withstood time. In fact, it has lasted longer than any country or collective group on earth – monasteries. But even in those, there is clear hierarchy and rules. Something to consider the next time you want to make a collectivist group.

RealityScan

RealityScan

Epic games worked with Quixel and just release the photogrammetry app RealityScan which turns smartphone photos into high-fidelity 3D models. The app is called RealityScan and is a paired down version of the desktop version of RealityCapture. Both combine a set of 2D images to make 3D assets. The idea is to enable game developers and other creatives to scan real-world objects at any time and any place for their projects (or the MetaVerse if that becomes a thing).

Engadget tried the iPhone app out and shows us how it works.

The scanning process begins with signing into your Epic Games account and taking at least 20 photos of an object from all sides. As you move your phone around, a real-time quality map shows how well you’ve covered it: green denotes well-covered areas, yellow could use more attention and red needs the most additional photos.

The app uploads and automatically aligns the images in the cloud as you take the photos. You can preview the model through the camera view and switch between the quality map and an in-progress, full-color render. When you want to crop it, it pops up 3D handles for you to drag around, ensuring it captures only the item, not the floor beneath it or background objects.

The process works best with simple items captured in even, indirect lighting (reflective or wet surfaces won’t capture well). It also appears to work best with larger objects, as my attempt to capture a small Mr. T action figure resulted in something that looks more like a pointillistic painting than a usable model.

The iPhone App version hasn’t got very good reviews (2.2 stars) – but it’s a start.

This idea isn’t new. There has been research and experiments in this space since the early 2000’s; but it’s an interesting attempt even if it seems to have a lot of growing pains to work out.

IBM PC Convertible

IBM PC Convertible

My very first computer was a TSR-80. I learned to first code out of necessity – you had to type in all the programs you wanted to play. My dad then purchased one of these wonderful beauties: The IBM PC 5140 Convertible.

Art Institute of Chicago

The computer was a miniaturized IBM XT 8088 system with only 2 floppy drives and no hard drive. Still, it was a huge step up with the ability to save and load programs from floppy disks.

I love that people try to preserve the history of these wonderful old machines – and you can find everything about the system including original boot disks, specs, and configurations. There also appear to be copies of the original boot disk and ROM set that work on MAME.
