We Chose to Go To The Moon. Forty-seven years ago, on July 20, 1969, a curious courageous species stepped onto the surface of a distant world. After surviving the explosive force needed to escape Earth's gravity and enduring a three-day ride through nearly empty space to enter lunar orbit, Neil Armstrong and Buzz Aldrin piloted a lander down to the surface, descended a ladder, and spent two hours working on the moon. Then, perhaps even more amazing, on July 21, they launched part of the Eagle lander back up to dock with Michael Collins in the orbiting Columbia, blasted out of lunar orbit and rode the tiny return craft back home, falling into the Pacific Ocean near Hawaii. Hundreds of thousands of mission contributors helped us cross the final frontier - and got us back safely.

"Over the next three and a half years, 10 astronauts [would follow] in their footsteps. Gene Cernan, commander of the last Apollo mission leaves the lunar surface with these words: "We leave as we came and, God willing, as we shall return, with peace, and hope for all mankind." [1]

Information may not be lost in black holes.
"[Y]ou can think of light rays on the surface of a black hole as a bundle of straws all pointing outward, trying to fly away at the speed of, of course, light. Because of the black hole’s immense gravity, they are stuck.

But the individual straws can slide inward or outward along their futile tracks, slightly advancing or falling back, under the influence of incoming material. When a particle falls into a black hole, it slides the straws of light back and forth, a process called a supertranslation.

That leaves a telltale pattern on the horizon..

Interesting work from Dr. Hawking, Dr. Strominger and postdoc, Alexander Zhiboedov, article by Dennis Overbye in the +The New York Times.

New calculations by Dr. Hawking and other researchers suggest that essential properties of whatever falls into these cosmic pits may survive.

What you quoted is an excellent description of the Bondi-Metzner-Sachs group, and how it acts on microstates of the black hole.  Finally, a good science writer!

Google’s artsy AI composes its first song

Have a listen and judge for yourself.

Last month, Google revealed its Magenta artificial intelligence project, which is dedicated to developing AI that are capable of creating various types of art, including music. The company gave a brief demonstration of its new program in action during Moogfest 2016, and now Google has released the first complete song created almost entirely by the AI. Researchers provided just four musical notes, which the AI then expanded into a 90 second composition. The music is a bit repetitive, but it still shows impressive work for an artificial intelligence, especially given the early stage of its development.

The Illustris simulation spans 13 billion years in time. End-to-end, it's 350 million light years across. MIT scientists start with basic physical laws, some initial conditions, and let it run. The results are remarkably similar to the universe we see.

Global warming: demand the truth

After announcements that 2015 was the hottest year on record and February 2016 was the hottest month, the news station CNN aired five times more fossil fuel advertising than actual climate reporting!

So, please sign this petition to CNN.  Tell them: start reporting on climate change.   And please reshare this message.

A study by the group Media Matters showed that the American Petroleum Institute is getting more coverage than actual news about global warming.  This doesn't even include the ads from individual fossil fuel companies and the Koch brothers.

Here's some actual news, in case you hadn't heard:

1) The extent of Arctic sea ice in June was the lowest in recorded history for that month of the year: 260,000 square kilometers less than ever before!   It's on track to break all records this year.

2) Recently every month from October until May has been the hottest on record worldwide.  June was the second hottest, since the El Niño is fading.

3) India recorded its hottest day ever on May 19th. The temperature in Phalodi hit 51 degrees Celsius (124 degrees Fahrenheit), and a nationwide drought has affected more than 300 million people marched on, leaving armed guards at dams, and reservoirs well below their usual levels.

4) Alaska, along with the rest of the Arctic, has experienced record-breaking heat this year.  Its average year-to-date temperature has been 5.5C above the long term average.

5) In the atmosphere, carbon dioxide has been increasing every year for decades - but this year the speed of increase is also record-breaking!   The increase for 2016 is expected to be 3.1 parts per million, up from an annual average of 2.1.

6) The Great Barrier Reef, a natural wonder and world heritage site, recently experienced its worst ever coral bleaching event.  An aerial study found that just 7% of the reef escaped bleaching. 

7) A new study in Nature argues that even despite the actions pledged in the Paris Agreement, the Earth is still on course for a temperature increase of 2.6 - 3.1C by the end of this century.  Read this:

http://www.nature.com/nature/journal/v534/n7609/full/nature18307.html

The Paris agreement is a step in the right direction, but we need to ratchet it up.  We can't afford to slack off now.  One piece of the puzzle is clear information about the crisis we're in.

Media Matters writes:

In Week After Hottest Year Announcement, CNN Aired Less Than One Minute Of Climate-Related Coverage And 13.5 Minutes Of Oil Industry Ads.

From January 20 to January 26, CNN morning, daytime and primetime programming included only 57 seconds of coverage about climate change or the announcement that 2015 was the hottest year on record. Over that same time period, CNN aired 13.5 minutes of American Petroleum Institute ads. The climate-related segments included one on the January 21 edition of Early Start, in which anchor Christine Romans reported that 2015 was the hottest year on record and that officials say “the planet is still warming with no apparent change in the long term global warming rate.” Additionally, CNN senior legal analyst Jeffrey Toobin briefly mentioned Republican climate science denial during a discussion of Hillary Clinton’s emails on Anderson Cooper 360, and CNN host Fareed Zakaria noted that the “The World Economic Forum said this year that the greatest global risk is the failure of climate change mitigation and adaptation,” during a Fareed Zakaria GPS segment about a study finding that humans have entered a new geological epoch known as the Anthropocene.

Following Announcement That February 2016 Was Most Unusually Hot Month Ever, CNN Aired Four Minutes Of Climate-Related Coverage And 10 Minutes Of Fossil Fuel Ads.

In the one-week period beginning March 17, when NOAA released data showing that February 2016 was the most unusually hot month ever recorded, CNN aired only four minutes of coverage about climate change or the temperature record during its morning, daytime, and primetime coverage. During that same time period, CNN aired ten minutes of American Petroleum Institute ads. On March 18, CNN anchors Christine Romans and John Berman delivered nearly-identical reports on February’s “astounding” temperature record during the 4 a.m. and 5 a.m. editions of Early Start, respectively, but neither explicitly mentioned climate change or the role fossil fuel pollution and other human activities play in driving climate change. The March 20 edition of Fareed Zakaria GPS featured an interview with astronaut Piers Sellers about his climate change advocacy, followed by a brief report about International Energy Administration (IEA) data showing a decline in carbon emissions from energy production, which Zakaria described as “some good news on the climate front” and a “welcome update in the climate battle.” Finally, on the March 20 edition of New Day Sunday, anchor Christi Paul reported that major cities around the world were participating in Earth Hour, an event meant to bring awareness to climate change, by switching off their lights.

Applied Mathematical Programming

You could obtain this book at the link below for a small fee, or directly from MIT.

Do not look at the date of this book (1977). It still provides the foundation of applied mathematical programming used today. And it is still used today in modeling courses as the main reference because it covers topics from A to Z in a practical and easy-to-understand manner.

Not only does this book show you how to model a wide array of problems, it explains the mathematical algorithms/techniques behind the modeling. And it combines the theory with tonnes of examples!!!

After reading this book, I finally have a true understanding of several topics such as linear programming, duality theory, sensitivity analysis, network/dynamic programming, integer programming, non-linear programming, and my favorite, modeling/solving large-scale problems (via column generation, decomposition, etc..)

The best thing about the book is that advanced topics do not seem advanced any more!!! I wasted my $$$ on too many Operational Research books that over-complicate topics; this book should be on every mathematical programmer's book shelf.

Many thanks to Bradely, Hax, and Magnanti for a job well done!

Primes aren't random. Not only does God play dice with the universe, he throws them for primes. Six-sided prime dice; like craps.

Very interesting. :)

You can simulate dice rolls with remainders of primes mod 7. The results look good, but chi-square test shows the fit is too good to mimic randomness.

lol, just take the remainder mod 2, and they are all the same!

edit: which begs the question, what happens in the limit as n goes to infinity of the distribution mod n?

Probably every generation has said that about pop music. Love my 80s music, but it was probably considered foul-mouthed, profane, and terribly raucous compared to the music of earlier generations. :)

On the likelihood of this being a simulation. Shared this one because it links to Professor Bostrom's paper. See also the Gizmodo article on 10 Reasons our Universe might Actually Be Virtual Reality. :)

The network speed is our speed of light.
The smallest "pixel" is our Planck Length.
The refresh rate is our Planck Time.

http://www.express.co.uk/life-style/science-technology/575653/The-Matrix-Universe-Planet-Earth-NASA-Scientist

"The idea that our Universe is a fiction generated by computer code solves a number of inconsistencies and mysteries about the cosmos."

"In his paper, Dr Bostrom suggested that "futuristic beings – human or otherwise – could be using virtual reality to simulate a time in the past or recreate how their remote ancestors lived."

Brown also quotes Rich Terrile, director of the Centre for Evolutionary Computation and Automated Design at NASA's Jet Propulsion Laboratory on the idea:

"What I find inspiring is that, even if we are in a simulation or many orders of magnitude down in levels of simulation, somewhere along the line something escaped the primordial ooze to become us and to result in simulations that made us – and that's cool."

[Edited to add]
* Everything travels through space-time at the space of light. If we move through space more quickly, then we move ever so slightly less quickly through time. When we add all four dimensions, they always add up to c.

If you want to know where Elon Musk got his Hypothesis that we're all likely living in a computer simulation (from recode conference: http://www.theverge.com/2016/6/2/11837874/elon-musk-says-odds-living-in-simulation), then see Nick Bostrom's theoretical paper. Professor Bostrom who wrote "Superintelligence" has been a major influence in Musk's thinking on AI.

Here is the equation for how in theory its several Billions to 1 odds that we are living a computer-ancestry-simulation:

If you read further into Bostrom's paper, he provides three plausible Post-human scenarios.
"There's a billion to one chance we're living in base reality," Elon Musk said tonight on stage at Recode's Code Conference, meaning that one of the most influential and powerful figures in tech...

OK, sorry +Boris Borcic for my pedestrian approach ;)
How about this, then?
If our piddling ability to simulate is enough to tip the odds of ours not being the basic reality, then surely the argument applies even more strongly to the ones simulating our reality! So, joke's on them! It's turtles all the way up!

He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. To him he's always doing both. ” ― James A.

A Few Favorite Quotes


A ship in harbor is safe. But that is not what ships are for.

Never give up
No matter what is going on
Never give up
Develop the heart
Too much energy in your country
Is spent developing the mind
Instead of the heart
Be compassionate
Not just to your friends
But to everyone
Be compassionate
Work for peace
And I say again
Never give up
No matter what is going on around you
Never give up
