John Bolton: “How do you feel about dead Americans?”

On Fox News September 3, here is John Bolton advocating a U.S. invasion of North Korea regardless of the cost in South Korean lives.

If I were the government of South Korea, I might be asking whether the benefits of the U.S. alliance outweigh the risk to my citizens, especially when my country has the technological and financial means to defend itself.

“China will prevent them from doing so”

From the Global Times, which is an English language paper published by the Chinese government:

Beijing is not able to persuade Washington or Pyongyang to back down at this time. It needs to make clear its stance to all sides and make them understand that when their actions jeopardize China’s interests, China will respond with a firm hand.

China should also make clear that if North Korea launches missiles that threaten US soil first and the US retaliates, China will stay neutral. If the US and South Korea carry out strikes and try to overthrow the North Korean regime and change the political pattern of the Korean Peninsula, China will prevent them from doing so.

China opposes both nuclear proliferation and war in the Korean Peninsula. It will not encourage any side to stir up military conflict, and will firmly resist any side which wants to change the status quo of the areas where China’s interests are concerned. It is hoped that both Washington and Pyongyang can exercise restraint. The Korean Peninsula is where the strategic interests of all sides converge, and no side should try to be the absolute dominator of the region.

terrifying Putin quote

Vladimir Putin either made a very terrifying statement here, or it just didn’t translate well.

An AI arms race doesn’t necessarily have to be a winner-takes-all scenario, though. Putin noted that Russia did not want to see any one country “monopolize” the field, and said instead: “If we become leaders in this area, we will share this know-how with entire world, the same way we share our nuclear technologies today.”

What a generous guy.

OECD Science, Technology and Innovation Outlook 2016

The OECD publishes a Science, Technology and Innovation Outlook every two years. They name “ten key emerging technology trends”:

  1. The Internet of Things
  2. Big data analytics
  3. Artificial intelligence
  4. Neurotechnologies
  5. Nano/microsatellites
  6. Nanomaterials
  7. Additive manufacturing / 3D printing
  8. Advanced energy storage technologies
  9. Synthetic biology
  10. Blockchain

This report has a little bit of everything. They talk about the “water-food-energy” nexus and how it is likely to interact with new technologies, climate change, the drop in public research funding and increasing importance of non-state actors, and cities as engines of innovation.

The last part of the report talks about the future of research, research funding, private vs. public research, and research policies. One term that was new to me was Responsible Research and Innovation (RRI) which attempts to manage risks and ethical concerns of new technologies.

Facebook let two chat bots talk to each other and they invented a new language

Facebook let two chat bots talk to each other and they invented a new language, one seemingly nonsense to humans but apparently they understood it.

…this nonsense was the discussion of what might be the most sophisticated negotiation software on the planet? Negotiation software that had learned, and evolved, to get the best deal possible with more speed and efficiency–and perhaps, hidden nuance–than you or I ever could? Because it is.

This conversation occurred between two AI agents developed inside Facebook. At first, they were speaking to each other in plain old English. But then researchers realized they’d made a mistake in programming.

“There was no reward to sticking to English language,” says Dhruv Batra, visiting research scientist from Georgia Tech at Facebook AI Research (FAIR). As these two agents competed to get the best deal–a very effective bit of AI vs. AI dogfighting researchers have dubbed a “generative adversarial network”–neither was offered any sort of incentive for speaking as a normal person would. So they began to diverge, eventually rearranging legible words into seemingly nonsensical sentences.

FDA has approved trials of Ecstasy to treat post-traumatic stress disorder

This is according to Science:

In people with PTSD, a small sensory trigger such as a sound or a smell can bring a traumatic memory rushing back. “The disabling element of PTSD is the fact that when the memory starts, the emotions completely override you and overwhelm the brain,” Nutt says. Studies suggest that MDMA can dampen the emotional response to the memory, allowing people to relive their trauma and work through it, he says. The MDMA-treatment consists of several sessions of psychotherapy, some conducted while the patient is under the influence of the drug…

A small U.S. study that first suggested MDMA could help treat PTSD was published in 2011. Since then, researchers in Canada, Israel, and the United States have jointly carried out larger phase II trials funded by MAPS; their results, which remain unpublished but have been reviewed by the FDA, were very good, says Doblin. Overall, 107 participants who had suffered from PTSD for an average of 17.8 years were treated in the phase II trials, Doblin says. Of the 90 patients who were available to be studied 12 months later, 61 no longer had PTSD.

In late July, says Doblin, MAPS and FDA agreed on how the coming phase III trials—usually the last hurdle before seeking a drug’s approval from regulators—should be conducted.

climate change and Hurricane Harvey

Michael Mann, a climate scientist at Penn State, has posted a long (for Facebook) article on Facebook about how climate change contributes to events like this. In short, climate determines the probability of a particular weather event occurring, but ultimately any one particular weather event is a roll of the (now slightly loaded) dice. Warmer water and warmer air than in the past have both made events like this more likely, and are making events like this more destructive when they do occur. The article has links to several journal articles which would be worth reading to know something about hydrology and climate change. But right now I can’t do that because I’m late for my job where I have to convince people I know something about, among other topics, hydrology and climate change.

Sea level rise attributable to climate change (some is due to coastal subsidence due to human disturbance e.g. oil drilling) is more than half a foot over the past few decades (see http://www.insurancejournal.com/…/sou…/2017/05/31/452704.htm for a decent discussion).

That means that the storm surge was a half foot higher than it would have been just decades ago, meaning far more flooding and destruction.

In addition to that, sea surface temperatures in the region have risen about 0.5C (close to 1F) over the past few decades, from roughly 30C (86F) to 30.5C (87F), which contributed to the very warm sea surface temperatures (30.5-31 C or 87-88F). There is a simple thermodynamic relationship known as the “Clausius-Clapeyron equation (see e.g. https://en.wikipedia.org/…/Clausius%E2%80%93Clapeyron_relat…) that tells us there is a roughly 3% increase in average atmospheric moisture content for each 0.5C (~1F) of warming. Sea surface temperatures in the area where Harvey intensified were 0.5-1C warmer than current-day average temperatures, which translates to 1-1.5C warmer than the ‘average’ temperatures a few decades ago. That means 3-5% more moisture in the atmosphere.

No Man’s Sky

I was somewhat of a gamer before I had children. That was then, this is now. Maybe when they are safely off to college. I don’t know how fun I would find this game, but the interesting thing is that the universe itself is procedurally generated, which means generated by the computer using a set of rules, rather than designed by the programmers. This means it can be enormous and you can just wander around in it as long as you want.
