NASA Chief Tells the Critics of Exploration Plan: "Get Over It"

mknewman Re:Radiation... (196 comments)

True, or a plasma jet (highly charged) coming out the back toward the sun. Brussard Polywell Fusion http://en.wikipedia.org/wiki/P... reactors that the Navy is building for next generation of ships (electromagnetic catapults and rail guns) would build a nice infrastructure not only for the interplanetary ship but also for the on-planet outpost.

Microsoft's Attempt To Convert Users From Windows XP Backfires

For my wife's computer was to wipe Windows and install Linux. She's getting used to it, and other than the way it looks sees very little difference. For me, it's way more supportable and stable.

Tesla Touts Cross-Country Trip, Aims For World Record

mknewman Re:But Does it Scale? (357 comments)

The Tesla Superchargers are not in heavily populated areas. They are along major routes in areas that aren't served by other charging possibilities. Also, if you look at http://www.teslamotors.com/sup... you will see that by 2015 they will have many, many more superchargers than the current cross country list. Eventually you will be able to do a battery swap. $60 and 90 seconds. Or you can wait for a charge and in an hour get a 'free' charge. Yes, I'm a fan, and no, I cannot afford one currently, but by the time the Model E comes out I will definately in the market. I just hope it doesn't look like a Smart and has performance similar to the current Model S.

Cold War Spoils: Amateur Builds Telescope With 70-Inch Lens

mknewman My big lens story (101 comments)

Years and years ago, around 1976, I had a tube type TV that went fritz so I took it to an Austin, Tx TV repair shop. The guy took it in the back to work on and while he was doing it I looked around his shop and there were quite a few very nice amateur astronomy photos, Jupiter, Saturn, the Moon and such. I was taking some astronomy classes at UT. When he came out we got talking and he told me he was into astronomy. Now, this shop was a WRECK, much like most TV repair shops I have ever seen. pretty much a dump. He asked me to come in the back to 'See something'. The guy was about 6'6" tall and BIG, and rough looking, and I am NOT, so I declined, but he insisted so I finally went through a maze of old junk, narrow dark halls, and finally got to the back of the store. I was kinda scared. He pointed to something on the ground. It was a round plug of glass on a large wooden palate. My jaw dropped, I asked him if it was what I thought and he confirmed it was a slug for a 6 ft telescope. I believe he said he got it at auction when a Swiss observatory had two made and the first worked out, so he got it cheap. It was unfinished, just a blob of glass, but at the time I'd only seen telescopes in the 36" range and this was huge! He was grinning ear to ear, and I was astounded. I believe his name was Chuck Knesek but I may be wrong or only close. It's been 35+ years. I never saw him again. If anyone knows what happened to him or his slug I'd love to know.

Leak: Almost a Third of Samsung Galaxy Gear Smartwatches Are Being Returned

mknewman Re:My Pebble does what I want out of a smartwatch. (365 comments)

I also have a Pebble, wear it a lot, like it enough, but hate having to charge it. Also, my phone doesn't do BT 4.0 so it uses a lot of power from the phone and the watch, and I have to charge the watch every 3-4 days (they say a week on 4.0). There is not enough room for more than 8 watch faces, and I wish it was color rather than B/W. I knew right from the start that Samsung's watch was going to be a dismal failure because it was way over priced, ugly as can be, and very little functionality.

First 'Habitable Zone' Galactic Bulge Exoplanet Found

Could a Grace Hopper Get Hired In Today's Silicon Valley?

mknewman Admiral Grace Hopper (608 comments)

Having met http://en.wikipedia.org/wiki/Grace_hopper briefly while I was at http://en.wikipedia.org/wiki/University_of_Texas_at_Austin back in the '70s I can say without a doubt she would be highly regarded in the current environment. She is known for COBOL but her accomplishments are many, including very early compilers and standards for FORTRAN. She was very influential to me. If she was 40 today I would easily imagine her leading a Silicon Valley company, as her tenure in the Navy was very similar, requiring leadership and technical capabilities, but she chose military service for her career, making what I consider very significant advances in computer science. She really was quite an imposing figure for a 90 lb grandmotherly woman. I wish I could have known her better. During many of her lectures, she illustrated a nanosecond using salvaged obsolete Bell System 25 pair telephone cable, cut it to 11.8 inch (30 cm) lengths, the distance that light travels in one nanosecond, and handed out the individual wires to her listeners. One of her great quips: "The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, "Do you think we can do this?" I say, "Try it." And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances."

Finance Firm Bloomberg Goes In For $80,000 On Ubuntu Edge Project

mknewman It's a great deal now. (98 comments)

The lower price is a great deal. It's much more powerful than phones currently on the market and is right in the same price range. I don't really understand why sales have stalled as this is going to be 2-3 years ahead of the market. Either that or it will drive the market to produce better phones. I for one bought 2. I'm surprised a bunch haven't been snapped up to sell on the secondary market, ie thEbay.

Elon Musknsays larger batteries on the way

mknewman mknewman writes  |  about 2 months ago

mknewman (557587) writes "ving a friendly chat with a group of Tesla owners in Norway, brand CEO Elon Musk intimated that more-powerful batteries could be on the way for the Model S. The most potent battery pack currently offered in the Model S holds 85 kWh of juice, or enough for 265 miles of driving.

Musk wasnâ(TM)t terribly specific, however: âoeThere is the potential for bigger battery packs in the future, but it would probably be maybe next year or something like that. The main focus is . . . how do we reduce the cost per kWh of storage in the battery pack?â In other words, Musk seems less concerned with stronger battery packs than making cheaper battery packs for the upcoming mid-size sedan, which is expected to be unveiled at the 2015 Detroit auto show.

âoeOur goal is to drop the cost per kWh by 30 percent to 40 percent.â And for that, Tesla would need to build more production capacity in the form of a âoegigafactory,â capable of churning out 30 gigawatt-hours annuallyâ"which Musk claims is more than the entire worldâ(TM)s lithium-ion factory production in 2012."

Virgin Galactic unveils it's other rocket engine

mknewman mknewman writes  |  about 3 months ago

mknewman (557587) writes "Two types of Newton engines have been designed for use on Virgin Galactic's two-stage LauncherOne rocket, which is destined to carry satellites into orbit from the WhiteKnightTwo carrier airplane starting as early as 2016. Future generations of the Newton could conceivably send rocket planes from, say, New York to London in 45 minutes.

The NewtonOne, an upper-stage engine designed to provide 3,500 pounds of thrust, has been run for its projected full mission duration of five minutes, Ringuette told NBC News during a tour of the test site. The NewtonTwo, which would serve as LauncherOne's first-stage engine, has been hot-fired for just a few seconds at a time so far. When it's ready for prime time, Virgin Galactic expects it to blast away for about two and a half minutes, with 47,500 pounds of thrust."

MoviePass institutes Countdown Timer "Feature"

mknewman mknewman writes  |  about 6 months ago

mknewman (557587) writes "MoviePass, the all you can eat, one movie per day service that models themselves after gym memberships where people buy the service and never use it, has driven one more stake through their user's hearts (gratuitous post-Halloween reference) in a 10/31/2013 email message where they describe new Features (?!) added to the apps:

"We're also excited to introduce a new feature: The Countdown Clock. This clock counts down the time until your next available screening. You will still be able to go to a movie each day, but there will be a 24-hour period between screenings. Your MoviePass app has already been updated, and you will notice these changes the next time you see a movie."

This constitutes a change in the terms of service and after a phone call they have confirmed that another announcement will allow users currently under contract to drop out within 14 days. There is heated discussion going on the MoviePass Facebook page."

WIMPs found?

mknewman mknewman writes  |  1 year,7 days

mknewman (557587) writes "Between 2006 and 2008 about four dozen physicists buried 19 Germanium-based detectors and 11 silicon-based detectors deep in a mine in Minnesota. They believed the Germanium detectors might be just right to capture the rare, but theoretically possible collision between a WIMP and an atomic nucleus. The silicon detectors were just there to confirm the result — i.e. if a Germanium detector recorded such a collision and a silicon detector did not, that would be good evidence for a WIMP.

After taking their data for three years the scientists got a ho-hum result — the Germanium detectors recorded two events, when on average they would have expected to see 0.9 events during the time period. This was not statistically significant, and moreover, they later concluded these events were attributable to the leakage of electrons.

Since the primary detectors showed no significant results, data collected by the silicon detectors, which could only detect WIMPs up to a mass of about 15 GeV were not analyzed.

Then, after some considerations, the physicists came to believe that maybe the WIMPs weren’t really, really big. So they went back and studied the silicon detector data and found three events, when they would have expected just 0.7 events during the time period of data taking. This is statistically significant.

So they published their results on Monday (see paper). Based upon their statistical analysis, they are 99.8 percent sure they have observed some WIMPs at a mass of about 8 GeV. But in particle physics, certainty doesn’t come until they are 99.9999 percent sure."

Space station's antimatter detector finds its first evidence of dark matter

mknewman mknewman writes  |  1 year,21 days

mknewman (557587) writes "Scientists say a $2 billion antimatter-hunting experiment on the International Space Station has detected its first hints of dark matter, the mysterious stuff that makes up almost a quarter of the universe.

The evidence from the Alpha Magnetic Spectrometer, revealed Wednesday at Europe's CERN particle physics lab, is based on an excess in the cosmic production of anti-electrons, also known as positrons. The AMS research team can't yet completely rule out other explanations for the bump, but the fresh findings provide the best clues yet as to the nature of dark matter."

SiriusXM arbritrarly restricting mobile apps to it's high speed data service

mknewman mknewman writes  |  1 year,26 days

mknewman (557587) writes "I am a Lifetime member on SiriusXM and have low speed Internet access, which is free with the account. It works fine on desktop platforms but not on mobile devices. The Android app says to upgrade to High Speed Data when I log in. Talking to the tech support they acknowledge this and basically say to upgrade, at $3.50 per month. Three problems with this, I don't want to pay $3.50 per month for service I already bought, and don't need the high speed fidelity as the low speed sounds just fine, especially on talk shows, and lastly the high speed data will use up more of my monthly allotment.

I have created an onliine petition to request them to unrestrict this. Please sign it if you agree.

NASA considering L2 outpost

mknewman mknewman writes  |  about a year and a half ago

mknewman (557587) writes "NASA has secretly been working on a plan to develop a manned outpost on the far side of the moon, but the lofty plan has been kept quiet until after the presidential election, according to media reports.

According to Space.com, the plan has probably already been cleared by the Obama administration. Officials kept the plan under wraps in case Mitt Romney won the presidential election.

The plan would set up a manned station in an area of space called the "earth moon libration point," CNN reported. The spot is a point in space where the gravitational forces of the moon and Earth are roughly balanced."

NRO gives NASA two space spy telescopes more powerful than Hubble

mknewman mknewman writes  |  about 2 years ago

mknewman (557587) writes ""The U.S. government's secret space program has decided to give NASA two telescopes as big as, and even more powerful than, the Hubble Space Telescope. Designed for surveillance, the telescopes from the National Reconnaissance Office were no longer needed for spy missions and can now be used to study the heavens. They have 2.4-meter (7.9 feet) mirrors, just like the Hubble. They also have an additional feature that the civilian space telescopes lack: A maneuverable secondary mirror that makes it possible to obtain more focused images. These telescopes will have 100 times the resolving power of the Hubble, according to David Spergel, a Princeton astrophysicist and co-chair of the National Academies advisory panel on astronomy and astrophysics.""

Did the universe begin as a simple 1-D line?

mknewman mknewman writes  |  about 2 years ago

mknewman (557587) writes "A refreshingly simple new idea has emerged in the complicated world of high energy physics. It proposes that the early universe was a one-dimensional line. Not an exploding sphere, not a chaotic ball of fire. Just a simple line of pure energy.

Over time, as that line grew, it crisscrossed and intersected itself more and more, gradually forming a tightly interwoven fabric, which, at large distances, appeared as a 2-D plane. More time passed and the 2-D universe expanded and twisted about, eventually creating a web — the 3-D universe we see today.

This concept, called "vanishing dimensions" to describe what happens the farther one looks back in time, has been gaining traction within the high energy physics community in recent months."

Galactic births came early

mknewman mknewman writes  |  about 3 years ago

mknewman (557587) writes "A distant galaxy with stars that began forming just 200 million years after the big bang has been discovered. The finding addresses questions about when the first galaxies arose and how early the universe evolved, scientists report.

The galaxy was spotted with the Hubble Space Telescope. It is visible through a cluster of galaxies called Abell 383, whose powerful gravity bends the rays of light like a magnifying glass. The so-called gravitational lens amplifies light from the distant galaxy, making it appear 11 times brighter and allowing detailed observations.

Infrared data from Hubble and NASA's Spitzer Space Telescope show the galaxy's stars formed when the universe was 200 million years old. Observations with the W.M. Keck Observatory on Muna Kea in Hawaii revealed the observed light from the galaxy dates to when the universe was 950 million years old. The universe formed about 13.7 billion years ago."
