Neil Tyson on the Paradox of Our Brains–Self Deluding, and Capable of Science | The Intersection

One of the recent episodes of NOVA ScienceNow was entitled “How Does the Brain Work?” On this week’s Point of Inquiry, I asked Dr. Tyson about the episode and what it found. Here’s a transcript, from around minute 6:20 of the show:

Tyson: Science exists, in part, in large measure, because the data taking faculties of the human body are faulty. And what science does as an enterprise is provide ways to get data, acquire data from the natural world that don’t have to filter through your senses. And this ensures, or at least minimizes as far as possible, the capacity of your brain to fool itself.

So to the neuroscientist, the brain is this amazing organ. And to the physical scientist, it’s like, ‘get it out of here.’ Leave it at home. Just bring your box, and have the box make the measurements. So that’s an interesting duality.

The brain–you can survive. My favorite among these is how easily the brain recognizes patterns even when there are no patterns there. You can statistically show there are no patterns, but your brain creates patterns. And the long term explanation for that has always been, it’s better to think that’s a tiger in the bushes, and then run away from it, and have it not be a tiger, than for it to be a tiger and not know it’s there and then you get eaten.

So the people who did not see patterns in the history of the species got eaten by creatures that were in fact making patterns in the visual din of the forest.

Q: The birth of science is, of course, the attempt to override this–and Francis Bacon talked about the “Idols of the Mind,” and that’s essentially what we’re now understanding through neuroscience. But it suggests there’s something about human nature where, scientific thinking is always going to be kind of the kid who gets left out of the group.

Tyson: I think the, if it were natural to think scientifically, science as we currently practice it would have been going on for thousands of years. But it hasn’t. It’s relatively late in the activities of a culture. Science as we now practice it…this is a relatively modern, that’s been going on for no more than 400 years. And you look at how long civilizations have been around, and you say, there’s a disconnect there.

Clearly, it’s not natural to think this way; otherwise, we would have been doing it from the beginning. And meanwhile, mathematics is the language of the universe–fascinatingly so–and yet science and math tend to be the two subjects that you will commonly hear people complain about in their time in school.

And so, I remain perennially intrigued by that fact: that the operations of the universe can be understood through your fluency in math and science, and it’s math and science that give people the greatest challenges in the school system.

Again, you can listen to the full episode here.


How To Build a Laser Tractor Beam (in Theory) | 80beats

Light is pushy. The physical pressure of photons is what allows for solar sail space missions that ride on sunlight, and what allows for dreams of lasers that will push those sails even faster. And light can trap objects, too: Optical tweezers can hold tiny objects in place. Pulling an object with light, however, is another matter. Though it’s counter-intuitive to think you could create backward-tugging force with a forward propagating laser and create a real-life tractor beam, the authors of a new physics paper write that they have shown a way it could be done.

Jun Chen’s research team says that the key is to use not a regular laser beam, but instead what’s called a Bessel beam. Viewed head-on, a Bessel beam looks like one intense point surrounded by concentric circles—what you might see when you toss a stone into a lake. The central point in a Bessel beam suffers much less diffraction than a standard laser, and so scientists can use them for precision operations like punching a hole in a cell.


The stars above, the luminescence below | Bad Astronomy

Sometimes the strangeness and beauty of nature come together in a scene so lovely, so surreal, that words fail. Such is the case in Phil Hart’s spectacular gallery of pictures showing bioluminescence in Gippsland Lakes in Victoria, Australia:

Oh, my. Can you believe this is real? I had to compress the file to get it to work on the blog, so please click it to see it in higher-resolution, and also look at the other astonishing pictures in his gallery.

Phil has a page describing in detail the pictures. In this case, a 1.5 hour exposure shows the glow from the trillions of Noctiluca Scintillans protists in the lake, as well as the trails of stars as they circle the southern celestial pole. That light on the horizon is not the Moon, but a house or some other man-made object. I love how the reflection curves and breaks up near the shore.

Phil’s pictures are simply breath-taking, and you just have to go and take a look. I am continually astonished at just how beautiful and surprising nature can be. It’s thrilling to see such disparate pieces ...

Taurus XL Fairing Fails To Separate – Again – Another Satellite Lost

NASA's Glory Satellite Fails To Reach Orbit

"NASA's Glory mission launched from Vandenberg Air Force Base in California Friday at 5:09:45 a.m. EST failed to reach orbit. Telemetry indicated the fairing, the protective shell atop the Taurus XL rocket, did not separate as expected about three minutes after launch."

Education Satellites Hitch Ride on Glory Mission

"P-PODs are aluminum containers measuring about 5 inches square by about 16 inches long. One P-POD will carry three CubeSats as an auxiliary payload aboard a Taurus XL on NASA's Glory mission."

NASA Creates Glory Satellite Mishap Investigation Board

"NASA's previous launch attempt of an Earth science spacecraft, the Orbiting Carbon Observatory onboard a Taurus XL on Feb. 24, 2009, also failed to reach orbit when the fairing did not separate. NASA's Orbiting Carbon Observatory Mishap Investigation Board reviewed launch data and the fairing separation system design, and developed a corrective action plan. The plan was implemented by Taurus XL manufacturer Orbital Sciences Corporation. In October 2010, NASA's Flight Planning Board confirmed the successful closure of the corrective actions."

NASA Buzzroom Is Broken. Please Fix It. (Updated with SOMD Response)

Keith's note: Yesterday I made note of a broken website - NASA Buzzroom's video page. One feature of this site is to grab videos posted on YouTube - automatically - and post them on a nasa.gov webpage and add a comment feature. Nice idea - it lets people see what others think about NASA. One small problem - humans are not in the loop at NASA. At one point I found a video that had been on nasa.gov for weeks that depicted a bloody lynching and featured a non-stop stream of profanity. NASA eventually got around to deleting it - once I complained (Google cached version).

I complained about lots of other videos that simply had no reason whatsoever to be on a taxpayer-funded space agency website. Eventually, once someone at NASA saw these videos mentioned by me, they were removed. This process seems to be working backwards. I find these videos simply by looking at the video page. NASA deletes them - but only when I make public note of their location. The NASA folks seem to be utterly incapable of making a decision as to what is in appropriate on their own - or identifying inappropriate videos that have been on their site for weeks (or longer). Nor are they able to fix the problem inherent in this website's design in the first place. Given the way they set up this site, it would seem that no one in SOMD's crack Internet squad ever tested this website before putting it online.

To compound things, they simply take videos off of their webpage because one person (me) complains. That's not right. As such, they clearly don't have any established guidelines for removal of videos either.

Right now a clip from the notoriously horrid Howard the Duck from the 1980s is gracing a nasa.gov page. It is harmless but pointless when it comes to space exploration. The NASA SOMD Internet guys will eventually delete it (this is the video on YouTube). But they will only delete it because I complained. FAIL.

Curiously, while NASA told me - officially - that the NASA lawyers had told them - that they could not link to this rather popular video "NASA - The Frontier Is Everywhere" that went viral a month or so ago, this NASA Buzzroom website links to it. So ... there is a bright side to the way this page works. Too bad the people who run this site do not take its design or upkeep seriously.

Pseudoscience and Profane Videos Featured Online at NASA.gov, earlier post

Keith's update: Beth Beck from SOMD sent me this in response to an inquiry as to how content is approve for posting on NASA Buzzroom. She is responsible for this page at NASA.gov. The full exchange is below. In a nutshell whoever is responsible for this website is incompetent and should be relieved of this responsibility. You see, this is the sort of material that the current process allows to be posted and approved:

Beth Beck: "Regarding the Buzzroom content collection process: The website automatically pulls content through social media aggregation tools under the following conditions:

* Directly originated from the official accounts: @nasa, @Lori_Garver, @StationCDRKelly, @Astro_Flow, @Astro_Cady, @Astro_Ron or @ShuttleCDRKelly (tweeters at the top box)
* Containing one of the words: nasa, nasatweetup, nasaed or nasatech.

The existing filtering system provides some limited filtering of incoming data that meets these criteria. Filtering is intended to remove r out tweets that are profane or have letters that aren't in the English alphabet.

There is no posting of info other than tweeting from the top box on the front page. NASA personnel review the content of the site, pull down content that is offensive, and update the filters as we see a problem. We had been in the process of considering other solutions involving a potential moderation interface and a popup box to explain the Buzzroom process, and will continue to review potential improvements. This is a collection site to gather the conversation in one place, not a place for creating new official NASA content which would require editorial review. We don't have editors who review twitter accounts, at this time, though that could change as time goes by."

My response: "The website that you are responsible for allowed a video to be posted on a nasa.gov web page that feature a graphic of an African American male with a noose around his neck with blood dripping down - and obtained substantial profanity and racial slurs. Your team then let it sit there for weeks until I complained - and then did not take it down for hours after you were informed. The original page was posted here.

A cached version of that page is here - a screen grab is here

Your response is incomplete and farcical to say the least since the process you describe allows such objectionable material to be posted  and reviewed and approved.  That means that this video was APPROVED for posting by your process. How on God's Earth could such a video EVER be approved? Whoever is responsible for this website is incompetent and should be relieved of this responsibility.  That appears to be you."

NASA ISS Payload Integration: Forever Slow?

Concept to Implementation in as Little as Six Months

"The National Laboratory Office sponsored some payloads that went into orbit in as little as 6 months, but that is not the norm at this time. A developer is already in the assembly process on their end for the payload, rather than in the development stage of their idea. An amazing turnaround like this is for known re-flight science, not for new payloads being assembled. What we are trying to do with National Lab is to use the processes and manage the integration in such a way that we can bring things in later than the normal flow. This is contingent on the National Laboratory model of the commercial or government agency having their funding and development ready to bring to the table. If they are waiting for anticipated funds to move forward with development, this significantly delays the progress."

Keith's note: Nice words but actions, as they say, speak louder. NASA's Space Station team (Mark Uhran et al) have had 20 years to figure this out and yet it still takes years, ponderous paperwork, and large piles of money to get virtually any payload onto the ISS. If Uhran's team really wants to be a "National Laboratory" in more ways than just name, then they need to do vastly better in this regard. Already (see below), things that could have been led by NASA in the past decade or so via on-orbit research had surged ahead on the ground because the agency has dragged its feet and is incapable and/or unwilling to try and find a way to make this amazing facility useful within the time frames that industry and academia work IN THE REAL WORLD.

Alas, the ISS National LAB CAN simply seeks to replicate all of NASA's current bad habits, adds a new name and logo and calls it "new". It is not "new" by any stretch of the imagination and NASA is only doing this because Congress got frustrated and ordered them to do so - in law.

Nanoracks are indeed cool and are in synch with the experimental mindset resident within many business and universities these days. If NASA is really paying attention and not just treating these Nanorack-class payloads as a novelty, they could serve to transform the ponderous process NASA uses to put payloads on the ISS. If, that is, NASA really wants this to happen and is not just doing this to pay lip service to a trendy concept. Right now, by the author's own admission these fast integration times are "not the norm at this time."

It needs to be the norm - for all payloads.

Using the ISS: Once Again NASA Has Been Left in the Dust, ealier post

"With the research results presented in these two papers, it would seem that structural information for biological molecules can now be obtained from vanishingly small biological samples - so called "nanocrystals" using a hard X-ray laser - on Earth - no space station required. So much for the official story NASA has told for 20 years that the ISS is crucial for such work."

HD Video From The Edge of Space – Director’s Cut

Keith's note: This is a much longer version of the previously released video - with music. If at all possible watch this at 720p resolution. As the payload slowly rotates you will see Discovery's vapor trail at the Earth's limb. The payload (with camera) swings to the west (where the sun is) and then swings back to the east, past Discovery's vapor trail, around to the west again and then continues to rotate to the east toward the fading vapor trail.

Educational Balloon Provides Space Shuttle Launch Images and Video From Over 110,000 feet

"Last week a balloon with a student-oriented payload shot high resolution photos and video from an altitude of over 110,000 feet of Space Shuttle Discovery as it climbed into space.These images and video were released today as part of a mission report provided by Quest for Stars representative Bobby Russell at the Next-Generation Suborbital Researchers Conference (NSRC) at the University of Central Florida."

GAO on NASA: Assessment of Selected Large-Scale Projects

GAO Report: NASA: Assessment of Selected Large-Scale Projects

"GAO assessed 21 NASA projects with a combined life-cycle cost that exceeds $68 billion. Of those 21 projects, 16 had entered the implementation phase where cost and schedule baselines were established. Development costs for the 16 projects had an average growth of $94 million--or 14.6 percent--and schedules grew by an average of 8 months. The total increase in development costs for these projects was $1.5 billion. GAO found that 5 of the 16 projects were responsible for the overwhelming majority of this increase. The issue of cost growth is more significant than the 14.6 percent average would indicate because it does not capture the cost growth that occurred before several projects reported baselines in response to a statutory requirement in 2005."

NASA OIG: NASA’s Facilities Maintenance

NASA OIG: Audit of NASA's Facilities Maintenance

"Many of NASA's facilities are in degraded condition and its maintenance backlog continues to grow each year. NASA's deferred maintenance estimate for all its facilities increased from $1.90 billion in fiscal year (FY) 2005 to $2.55 billion in FY 2010. Continued deferral of facility maintenance could result in unsafe working conditions and higher annual maintenance costs. From FY 2005 through FY 2009, deferred maintenance as a percentage of current replacement value increased, indicating that NASA's facilities were deteriorating. Although the overall deferred maintenance estimate in FY 2010 increased by approximately $6 million, deferred maintenance as a percentage of current replacement value decreased, indicating a slight improvement in the condition of NASA's facilities. This occurred due to NASA's efforts to replace or refurbish aged facilities."

Discarding The Shuttle

Discarding Shuttle: The Hidden Cost, Paul Spudis, Air & Space

"On February 15, 2011 a symposium entitled "U.S. Human Spaceflight: Continuity and Stability" was held at Rice University's James A. Baker Institute of Public Policy. Organized by George Abbey, the resident space expert at the Baker Institute, one might have suspected that it would be Shuttle-centric and indeed, it was. Many pertinent points relevant to the current discussion about NASA's human space program and its future (or lack thereof) came out of the presentations at this symposium."

NASA OIG on Webb and Recovery Act Funds

NASA OIG: NASA's Use of Recovery Act Funding for the James Webb Space Telescope Project

"Following multiple schedule delays and substantial cost growth, in 2009 the JWST Project received $75 million in Recovery Act funding intended to sustain the Project's workforce at a consistent level and maintain the baseline schedule for key development activities. We found that in using these funds, the JWST Project adequately addressed the requirements of the Recovery Act and related OMB guidance and delivered measureable outcomes consistent with Agency program and project plans and the goals of the Act. Specifically, we found that the $75 million in Recovery Act funds enabled 454 jobs to be retained on the JWST Project in the fourth quarter of FY 2009 and 149 jobs in the first quarter of FY 2010."

2011 Next-Gen Suborbital Researchers Conference a Hit, 2012 Follow-up Conference Planned

Suborbital

Washington, D.C. – The Commercial Spaceflight Federation is pleased to announce that the Next-Generation Suborbital Researchers Conference (NSRC) held in Orlando, Florida, this week set records for the number of presentations, sponsors and attendees. The annual conference brings the research and education communities together with suborbital vehicle providers and government funding agencies to explore the exciting new era of suborbital spaceflight.  CSF is a proud co-sponsor of the event, which was attended by about 350 people.

NSRC organizing chairman Dr. Alan Stern of Southwest Research Institute stated, “When we first conceived the idea for NSRC, many people were skeptical that such a meeting would generate much interest. Some even thought the research and education communities were simply not interested in suborbital science.  But just as in 2010, people have voted with their feet and come to NSRC by the hundreds. And once again we heard an amazing variety of proposals to exploit the capabilities of next-gen suborbital spaceflight — in fact, the number of presentations by researchers and educators increased 40 percent over last year.”

Stern added, “Clearly, many people are very interested in the capabilities that next-gen suborbital can provide to the research and education communities.”

Bretton Alexander, president of the Commercial Spaceflight Federation, stated, “The interest from researchers in these new commercial suborbital spacecraft was immediately apparent at this week’s Florida conference.  The excitement in the air was contagious. It’s becoming increasingly clear that scientists and educators can’t wait to put payloads and experiments onboard these vehicles.”

In addition to featuring more than 120 presentations spread among 20 technical sessions, this year’s NSRC also featured four discussion panels, a press conference, presentations or booths by 25 sponsors, and a public evening presentation by Virgin Galactic CEO George Whitesides.

“This year’s NSRC, like 2010’s, has been a galvanizing event for both the suborbital industry and the space research and education communities, demonstrating that the level of researcher and educator interest in next-gen suborbital is dramatically growing,” added Stern. “In response to the high turnout at NSRC in Orlando, we are today announcing that NSRC-2012 will take place in the San Francisco area next February 27-29, and will be hosted by NASA Ames Research Center. I’m looking forward to that already!”
