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. :)

Thanks, +John Cook
 
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. :)

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:
http://www.simulation-argument.com/simulation.html

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!

SciTech #ScienceSunday Digest - 22/2016.
Permalink here: http://www.scitechdigest.net/2016/05/mapping-ncrna-computers-driving-maths.html

Mapping ncRNA, Protein modularity, Better infrared light capture, Clutter busting robots, Computers driving maths & science, Automatic DNA origami, Scaling quantum dots, Cancer immunotherapies, Reducing amyloid plaques, Large-scale IoT.

1. Mapping Non-Coding RNA from Junk DNA
A new technique called LIGR-Seq captures interactions between different RNA molecules, isolates them, sequences them, and so identifies novel functions for new non-coding RNA molecules http://www.thedonnellycentre.utoronto.ca/news/shedding-light-%E2%80%98dark-matter%E2%80%99-genome. Types of non-coding RNA’s include the following: rRNA, tRNA, snRNA, snoRNA, piRNA, miRNA, and lncRNA. Only 2% of the genome codes for mRNA and proteins. The other 98% was thought to be junk, but it turns out that 50% - 75% of this “junk” is transcribed into non-coding RNAs now thought to have many functions in the cell and that previously had been incredibly difficult to identify, study, and characterise. This new tool changes that and should significantly boost our understanding of the cell and ways to manipulate it.

2. Better Understanding Protein Modularity and Design
A new evolutionary analysis of protein structure-function reveals strong conservation over time and across species for modular protein components that form loops for active sites that bind molecules or other proteins http://singularityhub.com/2016/05/25/scientists-unearth-key-evolutionary-link-in-proteins/. These modules are essentially used over and over again in different genes throughout different species and their identification provides avenues for directed synthetic biology applications, combining different modules to create proteins with novel functions. This phenomenon, known as hierarchical modularity has been observed in other complex man-made networks.

3. Efficiently Capturing Infrared Light
By etching thin grooves into semiconducting thin films a group has created ultraefficient infrared light absorbers capable of capturing 99% of infrared light instead of the conventional approaches that manage 7.7% http://www.eurekalert.org/pub_releases/2016-05/uos-obt052416.php. The structure of the grooves direct the light sideways into the material and drastically reduce reflections; I wonder if they are trying similar techniques for photovoltaics? Applications include much cheaper and more portable night-vision capabilities, thermal imaging generally, and perhaps types of sensing spectroscopy.

4. Robots Dealing with Clutter
New software is helping robots better deal with clutter via “rearrangement planning”, especially when pick-and-place becomes unfeasible or too time consuming http://www.cmu.edu/news/stories/archives/2016/may/robots-clutter.html. Obvious applications in sorting objects in complex environments and also in path planning when traversing cluttered and uneven surfaces. Next step is to incorporate additional levels and means of feedback for the robot to react and adjust to the environment as it goes about rearranging things. Meanwhile a new robot quickly sorts different types of rubbish for recycling applications http://spectrum.ieee.org/view-from-the-valley/robotics/industrial-robots/to-reycle-or-not-to-recycle-a-trash-robot-knows-for-sure.

5. Computers Solving Maths and Mining Science
The largest ever mathematics proof has been announced, in this case for computationally cracking the Boolean Pythagorean Triples problem, and is contained in a 200 Terabyte file http://www.nature.com/news/two-hundred-terabyte-maths-proof-is-largest-ever-1.19990?. Such brute-force proofs are becoming increasingly common and are no doubt useful, but people question whether they actually lead to increased mathematical understanding as is the case with general proofs. In related news machine learning techniques are being used to help researchers filter immense volumes of scientific papers and data to better direct research efforts, ask better questions, and reduce wasted efforts http://singularityhub.com/2016/05/26/machine-learnings-next-trick-will-transform-how-research-is-done/ and https://www.technologyreview.com/s/601589/the-first-visual-search-engine-for-scientific-diagrams/.

6. Automating DNA Origami Design
DAEDALUS is a new software algorithm that allows a user to design and specify a 3D structure, complete with holes, for which it then automatically designs the optimised sequence and number of DNA strands needed for form that particular DNA origami nanoparticle http://news.mit.edu/2016/automating-dna-origami-opens-door-many-new-uses-0526. Such a tool will further accelerate the field of self-assembled DNA nanostructures, and broaden its accessibility to more people across more fields. Applications include designing better gene-delivery vehicles, conjugation with proteins for functional targeting, functional memory blocks, basic nano-scale building blocks, functionalisation with metals for quantum dots, next-generation nanomachines and nanodevices.

7. Scaling Up Quantum Dot Production
Another recent technique for scaling up quantum dot production makes use of bacterial fermentation to do so https://www.ornl.gov/news/ornl-demonstrates-large-scale-technique-produce-quantum-dots. In this case zinc sulfide nanoparticles were fabricated by bacteria in a fermentation / biomanufacturing technique that results in the quantum dot nanoparticles being produced outside of the cell, and possibly 90% cheaper than other methods. Seems we really are getting closer to mass manufacturing of nanometer-scale quantum dots with magnetic, photovoltaic, and catalytic properties for a wide range of applications in electronics, energy generation and storage, and imaging.

8. Nuances in Cancer Immunotherapies
It turns out that techniques for activating a patient’s own immune cells to attack cancer cells may not be as effective as introducing immune cells taken from healthy volunteers https://www.fightaging.org/archives/2016/05/borrowed-immune-cells-to-fight-cancer/. The introduced cells turned out to be much better at recognising the cancer cells as cancerous, which the patient’s own immune system had otherwise failed to recognise; this is probably one of multiple mechanisms for the benefits of parabiosis. Immunotherapies are some of the most promising techniques currently being trialled and advances like this should only help to make them more effective.

9. Reducing Amyloid Plaques Systemically
It appears that organs and tissues peripheral to the brain play a role in removing and clearing Amyloid-beta protein and reducing the levels of Amyloid plaques the brain that are characteristic of Alzheimer’s Disease https://www.fightaging.org/archives/2016/05/the-possibility-of-reducing-amyloid-in-the-brain-by-reducing-it-elsewhere/. Amyloid produced in the brain appears to be somewhat cleared in the periphery, and boosting this clearance in the periphery helps to prevent Alzheimer’s Disease pathogenesis. This could be a source of low-hanging-fruit for temporarily pushing back Alzheimer’s Disease in humans to buy time for more advanced therapies.

10. First Large-Scale Internet of Things Network
Building of the first nation-wide network dedicated to the Internet of Things has been announced by Samsung, to be tested and rolled-out through South Korea http://nextbigfuture.com/2016/05/samsung-and-sk-telecom-to-build-world.html. This brings together a range of innovations in wireless communications, networking, data analytics, and electronic sensing to demonstrate a viable and effective nation-wide Internet of Things platform that people can expand and build applications on top of. As an example streetlights will collect weather and traffic information to facilitate lighting adjustments and pollution monitoring.

Functional memory blocks... Musk's neural lace... it's like the doors are opening up to work with one of the most important programming languages ever. These new industries will do more to alleviate suffering and realize potential than we could have imagined - and the advances are coming surprisingly fast!

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.

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.

More amazing footage of violent weather. Images of a recent EF-4 tornado: 267-322 km/h, 166-200 mph, devastating/extreme damage; well-constructed and whole frame houses completely leveled; cars and other large objects thrown and small missiles generated.[1]

Our planet is fascinating.

A windy day

This is a tornado that occurred in south-central Oklahoma on May 9th.   It's impressive what moist air can do when it's not in thermal equilibrium.

At first I couldn't remember where I found this video.  But Chris Greene found it:

https://www.youtube.com/watch?v=K1R_N_pysRs

Watch the whole thing!  At the end you'll see a car driving dangerously close to an oncoming tornado.  I wonder how that worked out.
