Is investment in Web 2.0 slowing?
Esther Dyson does business as EDventure Holdings, the reclaimed name of the company she owned for 20-odd years before selling it to CNET Networks in 2004. In the last few years, she has turned her sights towards IT and health care. She dedicated two issues of her newsletter, Release 1.0, to the topic (Health and Identity: No Patient Left Behind? in January 2005 and Personal Health Information: Data Comes Alive! in September 2005). Also in September 2005, she ran the Personal Health Information workshop that laid out many of the challenges still perplexing the health-care community.
Currently, she is on the board of directors of 23andMe and is one of the initial ten subjects of George Church's Personal Genome Project. Her primary activity is investing in start-ups and guiding many of them as a board member. Her board seats include Boxbe, CVO Group (Hungary), Eventful.com, Evernote, IBS Group (Russia, advisory board), Meetup, Midentity (UK), NewspaperDirect, and WPP Group and Yandex (Russia).
Some of her past direct IT investments include Flickr, Del.icio.us, BrightMail, Medstory and Orbitz. Dyson was the founding chairman of ICANN from 1998 to 2000, and was also chairman of the Electronic Frontier Foundation in the 90's. In 1997, she wrote Release 2.0: A Design for Living in the Digital Age, which appeared in paperback a year later as Release 2.1. In 1994, she wrote a seminal essay on intellectual property for Wired magazine.
Question: Is investment in Web 2.0 slowing?
Esther Dyson: I don’t know what where to point now it is of I do know that there has been way too much investment in the next new video there is a video that are video answer video whatever web 2.0 is basically is famed that somebody what is an investor to invest in is for an I can tell, and now everybody is claiming that they are actually web 3.0 of I think you are going to see right now there is still in over hang adventure money from last year that the investors are desperate to get invested but then I think your QMC quite to drop of going forward with the current state of the macro economy.
Question: Could a recession be a helpful development?
Esther Dyson: I prefer I much prefer you invested when the markets growing down or is down because then if you make a good investment decision you can do that actively you can put your money in there something and how it make it work, and you faced problems but you are invested at the top of the market the only way you can make a good decision is to avoid investing and so that’s get it you can be smart enough to avoid investing that you can’t do much, and that’s kind of frustrating so I prefer down markets because you can make money but doing active yes missed up markets where you can make money by doing passive our by selling sure which I don’t like to do when you can so sure in private deals anyway its personally I am kind of looking forward to few years, been not I don’t want to sound to globe, because he is going to hard for a lot of people, but I think there is being way too much forth and there is just a lot of I think ignore and over out of mistake and species bus about a lot of things that are really just the last time around I call them body parts they are companies their things that people are creating to be sold to somebody else and now maybe is going to buying them.

The web is saturated with video, Dyson says, and a recession will help drain the swamp.
It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction
- It appears that overdoses are increasing exponentially, no matter the drug itself
- If the study bears out, it means that even reducing opiates will not slow the trajectory.
- The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.
- The strongest material in the universe may be the whimsically named "nuclear pasta."
- You can find this substance in the crust of neutron stars.
- This amazing material is super-dense, and is 10 billion times harder to break than steel.
Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.
Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.
The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.
While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.
One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.
"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"
Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.
The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.
- Rising ocean levels are a serious threat to coastal regions around the globe.
- Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
- The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.
The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.
To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.
In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.
An "unthinkable" engineering project
"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.
One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.
The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.
But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.
Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.
"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.
"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."
A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.
"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."
