Anatomy of a Stock Selling Frenzy

In case you missed the brouhaha on Monday, United Airlines’ stock dropped from $12.50 to $3 per share in the matter of 15 minutes because of an Internet bot

The article then follows through the chain of events to explain exactly what happened. It is incredible to think that many people probably lost 75% of their money, and many others made 75% 15 minutes later.

by Marshall Brain

Humans and other primates have spent millennia evolving the ability to understand very subtle facial expressions. So if robots can mimic human expressions, they are likely to be better accepted and better “understood”. This fascinating video shows the latest in hyper-realistic robots, as well as more stylized robots that can nonetheless convey expressions:

Public Service Announcement - They are watching you at the airport

by Marshall Brain

There is something new in the TSA: behavior detection officers. It’s also called psychological screening. behavior detection officers WATCH passengers and try to recognize ourward signs of fear, stress or deception.

This article describes the effort in more detail:

How to Spot a Terrorist on the Fly

From the article:

Imagine if that screener had been taught to discern the signs of deception in a person’s facial expressions, voice, body language and gestures. With such training, he could have been confident enough to report the hijacker’s behavior. SPOT, which the Transportation Security Administration introduced this year at 14 U.S. airports, including Washington’s Dulles International, is the first attempt at using observational techniques as part of our security approach, and it is promising. Preliminary findings show that the overwhelming number of those who are taken out of line and detained for further investigation were intending to commit or had committed some kind of wrongdoing: They were wanted criminals, drug smugglers, money smugglers, illegal immigrants — and, yes, a few were suspected terrorists.

SPOT’s officers, working in pairs, stand off to the side, scanning passengers at a security checkpoint for signs of any behaviors on the officers’ checklist, such as repeated patting of the chest — which might mean that a bomb is strapped too tightly under a person’s jacket — or a micro-expression.

The items on the SPOT checklist are culled from law enforcement experience and research on deception and demeanor. What about your face, voice and body betrays the fact that you’re lying?

Good question - Why does oil calm water?

by Marshall Brain

If you watch this video, you can see a very curious effect. At the beginning of the video, you see a large puddle of water with wind-blown ripples on the surface. By pouring a little bit of oil onto the water, you can eliminate the ripples. As the video progresses and the oil spreads, the surface of the puddle becomes completely smooth:

This effect explains the term “oil slick”. If there is an oil spill, it will calm the water, making it appear smooth and slick.

Why does this happen? The layer of oil can only be a few molecules thick in the video, so how is it able to have such an obvious effect?

First it is helpful to understand waves:

Ocean Waves Styles and Patterns

Oil on the surface of water will calm capillary waves. It does not have an effect on swells. In the puddle seen above, all of the waves are capillary waves, so the water becomes completely smooth.

This paper contains a number of images:

Oils and surfactants

The main idea of the article is to show how ships can be detected by looking for the oil-calmed water behind them. In addition, figure 11.8 shows how ocean water with swells is calmed by oil. The capillary waves are removed but the swells remain.

Here is a complete answer to the question, starting on page 494. The answer itself is on page 501:

Crazy aircraft #54 - The ElectraFlyer C

by Marshall Brain

The ElectraFlyer C is a fully electric plane with the following features:
- 18 HP DC motor
- Lithium-polymer batteries
- 5.6 kilowatt-hour battery capacity
- Batteries weigh 78 pounds
- 75 volts at 200 amps at takeoff
- About 2 hours to recharge
- A full charge costs 60 cents for the electricity, and flies for about 1.5 hours
- Cruise speed is about 70 MPH
- Airframe is a Moni Motorglider

The most amazing thing is the flying cost, as described in this article:

ElectraFlyer-C electric mini plane makes flying cheaper than driving

From the article:

Costs? A full charge will cost you around 60 cents depending on where your power comes from. The battery pack can last 1000 cycles (charging and depleting) and then you would need to buy another lithium ion battery pack. The top end battery pack costs 8,500 $. So that is 1000 cycles = 1500 flying hours at a cost of 6.2 $ per hour! (cost of battery replacement divided by flying hours plus 60 cents per charging cycle).

Here is the plane in action and a description:

This automobile-of-the-future was called the Ford Nucleon, named for its highly unique design feature… a pint-size atomic fission reactor in the trunk.
