physical scientist

Not to be pugnacious, but math describes the world spectacularly well and we have no idea why. Why do we expect math to describe particles but not people? And how could you answer that if you don’t understand why it describes particles in the first place?

Certainly it’s easier to correctly use math to talk about the physical world (as opposed to the social world), and without math there’s a whole lot less you can say about the physical world than about humans and societies. But some of our most important insights into human behaviour are more or less mathematically derived, and we’re only getting better at that.

I think the notion that math cannot productively be used to study fields like history comes mainly from three sources.

First, there’s a lot of terrible work in quantitative social science (regressions regressions regressions). Ironically, though, this research typically comes from the people who think the least about how to use math when talking about people and who have the least faith in its usefulness. That’s a self-defeating prophecy.

Second, as I’ve written about many times before here, the tight coupling of math and the physical world has been a tremendous generator of wealth in industrial society. We poured money into getting really good at engineering and the industrial applications of physics and chemistry, thereby making mathematically intensive jobs extremely competitive, and then we developed a huge mental barrier about math where the Math People deserve big fat paycheques because they’re destined by the invisible hand to be really good at figuring out how much concrete goes where. This is an area where plenty of anti-capitalists have been completely bamboozled by the market into either hating or revering math.

Third, it actually is a lot easier to study particles with math than to study people with math. For whatever reason, the #UnreasonableEffectivenessOfMathematicsInTheNaturalSciences outstrips the  #UnreasonableEffectivenessOfMathematicsInTheSocialSciences. There’s an egotistical “humans are complicated” cop-out that a lot of people lean on, but of course particles are complicated too. I do think, though, that a big part of this story is that the warts of physical science are invisible to people in a way that the warts of social science aren’t. There are a bunch of reasons why the math that is usually employed in physical sciences both is and seems tougher; quantitative physical science rushed along rapidly for whatever fundamental reason and became pretty tough to understand pretty quickly, it was dramatically materially boosted in the last ~150 years by its industrial and wartime relevance (which is point #2), and there are also strong incentives for social scientists to tell societies exactly what to do (and look like big old dopes in a way physical scientists don’t) when the researchers themselves don’t actually have precise or accurate enough tools to properly know.

An interesting case here is medicine: they have an extremely similar mathematical toolbox to social scientists, they’re studying very similar social and psychological problems, and they constantly screw up, but even when bad quantitative medical research causes the President of the United States to throw the full weight of his office behind a flu vaccination campaign for a flu that never happens, nobody says that you just can’t use math to study medicine. The reason we don’t doubt their methodology much is that they’ve also had a colossal number of successes, which in my view isn’t because medicine is more mathematically tractable. It’s rather because medical researchers have infinite money from all the people who want to be healthy, and that means they have a ridiculous volume of research activity and their field moves forward super fast. Plus medical doctors get big paycheques and we have a habit of respecting people in proportion to how much they earn.

What I’m saying is: obviously you can use math and computers to study history and other social fields. People should do that (and others should study them qualitatively), and inevitably we’ll have good quantitative and computational models of historical processes. I also believe these subfields actually have a strong track record compared to many other social science subfields – for example, I think the definition of cliodynamics as written includes Marx. Of course this stuff is not easy to study, and it never will be, and there are tons of traps you can very easily fall into, but sooner or later someone will get really good at using tools like computer simulations to study human society and when they do they are going to learn a hell of a lot of really neat stuff.

Weird Things I've Done for Tabletop Games

I’ve researched “parasites”, “brain parasites”, and “brain parasite treatments” so I can plan how my character is going to try and handle her current problems.

Apparently you need, at minimum an anti-parasitic (of which it appears there are a few to choose from) and a corticosteroid. Judging the situation, she’ll also need surgery.
She’s the medic. I might be doomed.

A speed trap for dark matter, revisited

SYMMETRY MAGAZINE

By Manuel Gnida

A NASA rocket experiment could use the Doppler effect to look for signs of dark matter in mysterious X-ray emissions from space.

Researchers who hoped to look for signs of dark matter particles in data from the Japanese ASTRO-H/Hitomi satellite suffered a setback last year when the satellite malfunctioned and died just a month after launch.

Now the idea may get a second chance.

In a new paper, published in Physical Review D, scientists from the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), a joint institute of Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory, suggest that their novel search method could work just as well with the future NASA-funded Micro-X rocket experiment—an X-ray space telescope attached to a research rocket.

The search method looks for a difference in the Doppler shifts produced by movements of dark matter and regular matter, says Devon Powell, a graduate student at KIPAC and lead author on the paper with co-authors Ranjan Laha, Kenny Ng and Tom Abel.

The Doppler effect is a shift in the frequency of sound or light as its source moves toward or away from an observer. The rising and falling pitch of a passing train whistle is a familiar example, and the radar guns that cops use to catch speeders also work on this principle.

The dark matter search technique, called Dark Matter Velocity Spectroscopy, is like setting up a speed trap to “catch” dark matter.

“We think that dark matter has zero averaged velocity, while our solar system is moving,” says Laha, who is a postdoc at KIPAC. “Due to this relative motion, the dark matter signal would experience a Doppler shift. However, it would be completely different than the Doppler shifts from signals coming from astrophysical objects because those objects typically co-rotate around the center of the galaxy with the sun, and dark matter doesn’t. This means we should be able to distinguish the Doppler signatures from dark and regular matter.”

Researchers would look for subtle frequency shifts in measurements of a mysterious X-ray emission. This 3500-electronvolt (3.5 keV) emission line, observed in data from the European XMM-Newton spacecraft and NASA’s Chandra X-ray Observatory, is hard to explain with known astrophysical processes. Some say it could be a sign of hypothetical dark matter particles called sterile neutrinos decaying in space.

“The challenge is to find out whether the X-ray line is due to dark matter or other astrophysical sources,” Powell says. “We’re looking for ways to tell the difference.”

The idea for this approach is not new: Laha and others described the method in a research paper last year, in which they suggested using X-ray data from Hitomi to do the Doppler shift comparison. Although the spacecraft sent some data home before it disintegrated, it did not see any sign of the 3.5-keV signal, casting doubt on the interpretation that it might be produced by the decay of dark matter particles. The Dark Matter Velocity Spectroscopy method was never applied, and the issue was never settled.

In the future Micro-X experiment, a rocket will catapult a small telescope above Earth’s atmosphere for about five minutes to collect X-ray signals from a specific direction in the sky. The experiment will then parachute back to the ground to be recovered. The researchers hope that Micro-X will do several flights to set up a speed trap for dark matter.

Anyway so Jake and Dirk were raised in some kind of ectobiological lab by Alternians who are studying the biological ins-and-outs of the human race now that they, yknow, have exterminated Earth.

Dirk and Roxy lived in containment together until one night she just… disappeared. He was so stricken with grief and confusion over what(ever) happened to her he stops eating and caring for himself and, like he’s some kind of pet, the Trolls watching him don’t want to lose him too so they shove in an ectokid from another project into his home to lift his spirits.

Jake’s project had him living in a containment unit meant to simulate humans in a far more primitive environment filled with Earth plants and trees and genetically engineered dangerous wildlife. He doesn’t take well to the cold metallic walls of Dirk’s cell but he enjoys the movies Dirk showcases to him as a hesitant offering of let’s-not-murder-each-other-because-two-blue-bloods-have-a-bet-over-who-will-win.

Jake’s never been around another human before so he’s equal parts apprehensive and touch-starved. Dirk starts to form Feelings, so god knows how that’s going to play out.

Could Déjà Vu Be A Way To Obtain Information From Other Dimensions?

Deja vu is one of the little-known and mysterious phenomena of our psyche. Many people sometimes feel that a situation in their life has already been experienced before in all the details. But how and when? This phenomenon is called déjà vu, which in French means ‘already seen’. It is a condition in which a person feels that once he already experienced a situation of the present, but the feeling is not associated with a specific moment of the past, but refers to the past in general.

Deja vu is quite common. Psychologists believe that 97 % of people have experienced it at least once. Sometimes people are afraid of deja vu and worry about their mental health. What lies beyond human understanding, always frightens us.

The reasons that cause the phenomenon are still not clear. It might be caused by the processes in the parts of the brain associated with memory and perception. There is a hypothesis that sometimes the perceived information gets to the memory areas sooner than to the area of the primary analysis. Thus, the brain, comparing the situation with its ‘neurocopy’ already received by the memory, concludes that it already happened before.

Suppressed Science that has the potential to elevate humanity.

You are being lied to, and this is no minor white lie… The model of reality you have been taught is a misconstrued religious interpretation of Newtonian Physics. Many have preached about this but only within the past several decades do we have scientific evidence to back up this assertion.

Before I elaborate on this subject I’d like to clarify that everything I am about to disclose is scientifically viable, proven, and unless you are searching for these answers this information is conveniently hidden from you, washed out by our educational institutions and celebrity scientists.

Physical matter reality is not real, atleast not in the way you perceive it to be. Nearly a century ago it was discovered that matter only exists in a particle state when it is observed. When it is unobserved reality only exists as fundamental waves of probability (potential energy). Upon which being observed it’s wave function collapses into the holographic projection of a particle. The well tested experiment that proves this postulation is popularly known as “The Double Slit Experiment”. For you computer geniuses out there this will be much easier to understand, as fundamental reality exists only as information(likened to the binary code of 1’s & 0’s that generate all of the wonderful experiences on our computer screens.) Your body is the computer, the receiver and processor of this corporeal information, and your mind is the rendering engine. You are the operator, the administrator of the computer, instead of your experience being rendered on a screen it is rendered as a 3D holographic projection we call “reality”.

Logically we can deduce that all we perceive as the external world only exists internally, everything that you know, feel, see, and experience all exists within your mind, the only thing that makes something “real” in your mind is your ability to render it into being. 96% of the universe remains completely invisible to us, this is information we aren’t even remotely capable of processing and rendering(though that doesn’t mean we won’t ever achieve the level to do so.)

My point being is that everything in reality exists as thoughts, your car is a package of tightly packed information into one “object” we have been able to separate and divide from the surrounding thoughts, such is the same with everything in this reality. Because everything you experience is within you, and is merely a thought, you can logically deduce that everything is an extension of yourself… In other words “it is you” only you’ve forgotten and think that it is not.

Why is this being suppressed? Why isn’t this being taught, and being hidden from your consciousness. Because believe it or not there are those who see you as property, as livestock, and wish to use you to power their institutions and reap the rewards of your work & creativity. Some have it in their minds that they are superior to you and know best how to guide the future of humanity. This view of supremacy is extremely dysfunctional and leads to the conclusion that the many can suffer as long as the few superiors survive to guide “progress”. They have discovered this truth before you and let it go to their heads, realizing that we are all God, they have decided to play God and have become addicted to power. The illusion is that their power is your own, you’ve only got to take it back.

Why am I telling you this? And why am I delving into crazy conspiracy? Not to scare you, not to get you to jump on a conspiracy bandwagon, far from it(because the conspiracy has little importance beyond understanding its presence). I tell you this in hopes you reclaim the crown that was stolen from you at birth, the crown that deemed you ruler of your life. I want to give you the gift you were always meant to have, the sovereignty of your being. You are everything that you see and experience, not this ego that confines you to a small fleshy body trapped in a billiard ball world of atoms upon which consciousness somehow manifested. It is the reverse, reality emerges from consciousness. You are all that is, was, and ever will be, it will all come from you. Death is an illusion, you cannot kill a thought and the only “real” things are thoughts. There are no limits to what you can do, only the limits you’ve been conditioned to place on yourself.

The age old saying “Mind over matter” holds credence since matter arises from the mind. Your mind is what affects the wave function variables, the information that makes up reality. Realize the power of your thoughts, and that their is no fundamental difference between your imagination and physical matter reality. Know that whatever you think about is your intent, and your intent manifests itself into the physical world.(so be careful what you wish for or dwell on) Physical matter reality only exists as a medium to understand and interact between your consciousness and the vast many others that populate this reality.

Go forth, do your own research, and create an experience worth living for, you are so much more than you realize. Discover for yourself the new & old world of these scientific developments and break free from the system!! You don’t have to partake in the matrix if you don’t wish to.

10 ways immigrants help to grow the American economy

After receiving a comment that was obviously very misinformed on immigration in the United States, I felt the need to share this: 

America is a nation of immigrants. Our American journey and our success would simply not be possible without the generations of immigrants who have come to our shores from every corner of the globe. It is helpful to take a moment to reflect on the important contributions by the generations of immigrants who have helped us build our economy, and made America the economic engine of the world. How do immigrants strengthen the U.S. economy? Below is our top 10 list for ways immigrants help to grow the American economy

  1. Immigrants start businesses. According to the Small Business Administration, immigrants are 30 percent more likely to start a business in the United States than non-immigrants, and 18 percent of all small business owners in the United States are immigrants. Immigrant-owned businesses create jobs for American workers. According to the Fiscal Policy Institute, small businesses owned by immigrants employed an estimated 4.7 million people in 2007, and according to the latest estimates, these small businesses generated more than $776 billion annually. 
  2. Immigrants are also more likely to create their own jobs. According the U.S. Department of Labor, 7.5 percent of the foreign born are self-employed compared to 6.6 percent among the native-born. 
  3. Immigrants develop cutting-edge technologies and companies. According to the National Venture Capital Association, immigrants have started 25 percent of public U.S. companies that were backed by venture capital investors. This list includes Google, eBay, Yahoo!, Sun Microsystems, and Intel. 
  4. Immigrants are our engineers, scientists, and innovators. According to the Census Bureau, despite making up only 16 percent of the resident population holding a bachelor’s degree or higher, immigrants represent 33 percent of engineers, 27 percent of mathematicians, statisticians, and computer scientist, and 24 percent of physical scientists. Additionally, according to the Partnership for a New American Economy, in 2011, foreign-born inventors were credited with contributing to more than 75 percent of patents issued to the top 10 patent-producing universities. 
  5. Immigration boosts earnings for American workers. Increased immigration to the United States has increased the earnings of Americans with more than a high school degree. Between 1990 and 2004, increased immigration was correlated with increasing earnings of Americans by 0.7 percent and is expected to contribute to an increase of 1.8 percent over the long-term, according to a study by the University of California at Davis. 
  6. Immigrants boost demand for local consumer goods. The Immigration Policy Center estimates that the purchasing power of Latinos and Asians, many of whom are immigrants, alone will reach $1.5 trillion and $775 billion, respectively, by 2015. 
  7. Immigration reform legislation like the DREAM Act reduces the deficit. According to the nonpartisan Congressional Budget Office, under the 2010 House-passed version of the DREAM Act, the federal deficit would be reduced by $2.2 billion over ten years because of increased tax revenues. 
  8. Comprehensive immigration reform would create jobs. Comprehensive immigration reform could support and create up to 900,000 new jobs within three years of reform from the increase in consumer spending, according to the Center for American Progress. 
  9. Comprehensive immigration reform would increase America’s GDP. The nonpartisan Congressional Budget Office found that even under low investment assumptions, comprehensive immigration reform would increase GDP by between 0.8 percent and 1.3 percent from 2012 to 2016. 
  10. As a nation of immigrants, we must remember that generations of immigrants have helped lay the railroads and build our cities, pioneer new industries and fuel our Information Age, from Google to the iPhone. 

As President Obama said at a naturalization ceremony held at the White House… 

The lesson of these 236 years is clear – immigration makes America stronger. Immigration makes us more prosperous. And immigration positions America to lead in the 21st century. And these young men and women are testaments to that. No other nation in the world welcomes so many new arrivals. No other nation constantly renews itself, refreshes itself with the hopes, and the drive, and the optimism, and the dynamism of each new generation of immigrants. You are all one of the reasons that America is exceptional. You’re one of the reasons why, even after two centuries, America is always young, always looking to the future, always confident that our greatest days are still to come.

We celebrate the contributions of all Americans to building our nation and its economy, including the generations of immigrants.”

If you don't trust bio majors with something as basic as telling you what gender is, then what's the point of this entire field of science? Why not dismantle it? I've always thought that science was a tool for gaining knowledge about the physical world and that scientists were experts at wielding this tool, however if the general public doesn't trust these experts because truth is uncomfortable then we might as well scrap the whole thing. Let's just kill science! #BurnBooks

I don’t trust them on that authority. I will tentatively trust experts in their field. And get many perspectives. Science isn’t as clear cut as everyone would like to believe.

No. Not biology major collegw kids.

You literally can't know how much someone studies from a bunch of photos though? It doesn't show how slow or fast it takes to decorate a desk either...your post was kind of condescending dude.

Ayyyy before you go all raging at me for no reason, AS I SAID, I didn’t meant it as a bad thing and also I mentioned why I think that in the ask I got previously -.- I didn’t trash talk anyone, so please? Relax a little. It was a normal discussion question, asking if it only looks like that to me. 

I posted what was on my mind for a while now since I always see people reblogging those kind of posts. Of course I don’t know how long it takes to put all that stuff for photos together, I never do that. I like working in a mess, it helps me, so I might just be a special case. 

So about that AU that popped into my head.

It was a blind AU.

So like, as a young teen. Like 11 or something. Yang gets into a dust accident
Specifically red dust and she looses her vision.

Her iris turns white too.

So she becomes blind.

So like, the Schnee corporation has never heard if anyone go blind with red dust, they usually explode so they tell the head honcho aka Papa Schnee

And he’s super intrigues so he’s like, get he kid and we’ll keep a close eye in her.

So Yang has to live with the Schnee family while being under close observation and Weiss is li, who’s the new kid???

Cause Yang joins her in her physical training cause the scientists and doctors say she needs to be kept in tip top shape and Papa schnee appoints Weiss to he her guide and eye.

So when they’re introduces Yang goes all up in Weiss’s face and touches and she’s like, ‘Whoa you have a scar!’

And Weiss is just blushing like mad.

But they end up being close cause Yang totally needed to get used to not seeing.

And there’s probably more but that’s all I’ve got for now.

I’ll doodle some for it tomorrow.

OVERWATCH
Tracer

“Cheers, love! The cavalry’s here!”

The former Overwatch agent known as Tracer is a time-jumping adventurer and an irrepressible force for good.

Lena Oxton (call sign: “Tracer”) was the youngest person ever inducted into Overwatch’s experimental flight program. Known for her fearless piloting skills, she was handpicked to test the prototype of a teleporting fighter, the Slipstream. But during its first flight, the aircraft’s teleportation matrix malfunctioned, and it disappeared. Lena was presumed dead.

She reappeared months later, but her ordeal had greatly changed her: her molecules had been desynchronized from the flow of time. Suffering from “chronal disassociation,” she was a living ghost, disappearing for hours and days at a time. Even for the brief moments she was present, she was unable to maintain physical form.

Overwatch’s doctors and scientists were stumped, and Tracer’s case seemed hopeless until a scientist named Winston  designed the chronal accelerator, a device capable of keeping Tracer anchored in the present. In addition, it gave Tracer the ability to control her own time, allowing her to speed it up and slow it down at will. With her newfound skills, she became one of Overwatch’s most effective agents.

Since Overwatch’s dissolution, Tracer has continued to right wrongs and fight the good fight wherever the opportunity presents itself.

Space dust is filled with building blocks for life

A study of teeny-tiny meteorite fragments revealed that two essential components of life on Earth as we know it, could have migrated to our planet on space dust.

Researchers discovered DNA and amino acids components in a smidgen of a space rock that fell over Murchison, Victoria, in Australia in September 1969. Previous studies of the meteorite revealed organic material, but the samples examined then were much larger. This study would lend more credence to the idea that life arose from outside of our planet, researchers said in a statement.

“Despite their small size, these interplanetary dust particles may have provided higher quantities and a steadier supply of extraterrestrial organic material to early Earth,” said Michael Callahan, a research physical scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md.

Amino acids are the basis of proteins, which are structures that make up hair, skin and other bits of living creatures. DNA is a molecule that contains information on building and running an organism.

Meteorites such as Murchison are rare types of space rocks: the carbonaceous chondrites make up less than 5 percent of meteorites found on Earth, NASA said. Further, the molecules discovered in these space rocks are usually in miniscule concentrations of parts-per-million or parts-per-billion.

These factors have researchers questioning how significant the carbon-rich rocks themselves were in bringing life to Earth. Space dust, however, is more plentiful as it is constantly available from comets and asteroids shedding debris in their travels through the solar system.

The Murchison study (a proof of concept for further work, the researchers say) found life’s building blocks in a sample that weighed about the same as a few eyebrow hairs. The 360-microgram sample was about 1,000 times smaller than a typical sample analyzed by researchers.

This micro-sample required a more sensitive technique than usual to extract the information scientists needed. A nanoflow liquid chromatography instrument organized the molecules, which were then ionized with a nanoelectrospray for analysis in a mass spectrometer.

NASA and other agencies have dealt with small sample sizes before, such as on the Stardust mission that collected particles from Comet Wild-2 and returned them to Earth in 2006. Researchers anticipate the techniques they are using today could be used for other missions in the solar system, especially for sample-return missions.

“This technology will also be extremely useful to search for amino acids and other potential chemical biosignatures in samples returned from Mars and eventually plume materials from the outer planet icy moons Enceladus and Europa,” said Goddard astrobiologist Daniel Glavin, who was co-author on the research.
