What good is scholarship when a layman can see right through it? There’s an unsatisfying emptiness at the heart of modern secular science.Some scientists just don’t get it. Ponder the scientist who says that everything evolves, and the only truth is that there are no truths. How can such a person not see that the statement is self-refuting? Consider a book review by Anil Ananthaswamy in Nature. Ananthaswamy is certainly a learned man. But in “A physicist probes the metaphysical,” where he “examines Alan Lightman’s reflections on the tensions between empiricism and experience,” he falls right into his own materialistic pit.As a physicist, he knows there are no absolutes. The idea of a fixed and motionless Earth was disproved in 1851 by the “slow rotation of the plane of a swinging pendulum” — physicist Léon Foucault’s experiment — which could be explained only if the planet, not the pendulum, was rotating. Discoveries of the electron and radioactivity showed us that even atoms, once thought indestructible, were anything but. Next, Albert Einstein demolished Newtonian notions of absolute space and time. Then came quantum mechanics, with its claims of uncertainty and indeterminism.For anyone looking to science for assurance, the bottom falls out. So, Lightman looks past it. “I am a scientist, but I am not a swinging bob on a string,” he writes.After a brief account of Lightman’s imaginary dialogue with philosophers and religious figures, Ananthaswamy proceeds to argue that Lightman really is a bob on a string. But he doesn’t see that he is one, too. He speaks as if he has scientific authority to embrace truth with a capital T, when he just said there aren’t any absolutes. Who is he kidding but himself?Therein lies the book’s Achilles heel: it makes little mention of the research on perception that calls into doubt the ‘truth’ of subjective experiences, no matter how real or exalted they feel. Modern neuroscience tells us that what we perceive is not a bottom-up reconstruction by the brain of what’s out there. Rather, it is the brain’s prediction about the probable causes of sensory inputs.Someone should tap Anil on the shoulder and say, ‘Pssst… your book review is a subjective experience. It has no truth in it, no matter how exalted it makes you feel.’Reviewers such as Ananthaswamy routinely employ logic and conscience as if these really are absolute and timeless, to the extent that humans can aspire to them. But as Lightman unsuccessfully tried to convince him, even scientists cannot live with the meaninglessness of materialism. Look at how he dismisses Christian certainty:“Augustine’s certainties were absolute,” Lightman writes, contrasting these immutable religious ideas — such as the immortal soul — with science’s ever-evolving view. Yet, he argues, science, too, longs for an absolute in a final ‘theory of everything’, and has its article of faith: “that the physical world is a territory of order and logic”.Lightman’s scope is sweeping, but he doesn’t dig deeply enough. For instance, he expresses disbelief in bardo — the Tibetan Buddhist term signifying the transitory state between death and rebirth. He writes: “I ask for some kind of evidence for all things I believe — even if it is evidence from a personal or transcendent experience. And I insist on evidence for any statements that concern the physical world.” Certainly, there is no ‘evidence’ for bardo, independent of the subjective experiences of Tibetan Buddhists. But Lightman stands by his own subjective experience of perceived ‘oneness’ with something larger than ourselves. A rigorous scientific approach would question the veracity of all subjective experiences, not just those that seem unreasonable at first blush.Lightman’s failure to see his own preference for subjective experience is what Anil calls the book’s “Achilles heel.” Well, if it’s an Achilles heel for Lightman, it is just as much one for Ananthaswamy. Science collapses into the very subjectivist pit that Lightman desperately sought to avoid.What makes someone believe or reject science? Quality of recordings (Science Daily). Here’s another case where some scientists just don’t get it. They worry about public doubt about some of their pompous claims. Some ‘researchers’ at Australian National University had an ‘Aha!’ moment. They hypothesized that the reason people reject science is a factor of recording quality. Improve the sound, and people will believe. They ran experiments that seemed to confirm their hypothesis. And yet much of the so-called science (including evolutionary materialism) that the public doubts is not recorded; it’s in print! This shows the shallow thinking behind some experimental science. It’s orthogonal to the real problem. It’s like focusing on the static in a TV program instead of the message. We would say the real problem behind “what makes someone believe or reject science” is the content, not the medium.My path to contentment (Science Magazine). This is a poignant short autobiography by Edmond Sanganyado, a poor man from Zimbabwe who aspired to be a scientist. He made his family and his tribe proud, becoming the first in his village to get a PhD. But did it lead to a contented life? He found himself disillusioned with the processes in Big Science that led to a rat race to get ahead. Try as he did, he missed out on prestigious positions he longed for. He was haunted by a fear of failure, even though people back home respected him. His balloon deflated when an ideal position in Europe came and went; he didn’t get the job.With that, my desire to be respected and valued by top researchers died. I was done trying to join the elite. After all, I couldn’t change the grad school I attended or the ranking of the journals in which I had published. And I remembered the words of my mental health counselor in grad school, when the stress of writing a dissertation, job hunting, and trying to be there for my young family had driven me into depression: “Edmond, you do not need documented validation for you to know your worth.” At that time, the advice didn’t make sense. After all, I needed good publications to graduate. I needed better publications to get a postdoc and ultimately a tenured position. But now, it finally sank in. The rat race had to stop. I resolved that what mattered most was my commitment and diligence rather than what others thought of my scientific contributions. I could do great science at a small, unknown university. So I decided to take the position in China.I’ve been here a year now. Navigating the language and cultural barriers has been an enjoyable adventure. Focusing on what excites me rather than trying to fulfill the expectations of academia has been liberating. And whenever I find myself slipping back into old ways of thinking, I remember my wife’s question: “How many orphaned kids from an unknown farming town graduated from high school and have an undergrad degree or a Ph.D.?” With that, I am proud of what I have accomplished, and that is enough.Did anyone think to ask Dr Sanganyado whether contentment can be found in a test tube? Did anyone ask him if contentment is a product of mindless evolution? Did anyone ask him if validation, longing, respect, liberation, and pride of accomplishment are mere subjective experiences with no connection to reality? Learning from Ananthaswamy might have sent the poor PhD from Zimbabwe back into depression, and despair.Did anyone think to teach Dr Sanganyado the Christian secret of contentment? “But godliness with contentment is great gain, for we brought nothing into the world, and we cannot take anything out of the world” (I Timothy 6:6-7). The pursuit of godliness must come prior to the pursuit of the other things. The Apostle Paul’s circumstances swayed between respect and great need. But with godliness as his priority, he was able to say, “I have learned in whatever situation I am to be content” (Philippians 4:11).(Visited 393 times, 1 visits today)FacebookTwitterPinterestSave分享0
Share Facebook Twitter Google + LinkedIn Pinterest Dry Conditions ContinueLimited rain fell over the week, extending a dry spell as growers gear up for harvest, according to Cheryl Turner, Ohio State Statistician for the USDA’s National Agricultural Statistics Service. There were 5.6 days available for fieldwork for the week ending September 17, 2017. Very little residual rainfall from Hurricane Irma was available, and most of the state’s rain fell in southern and central Ohio. Temperatures were slightly above normal in the northeast part of the state, and a couple of degrees cooler than normal in the southwest. The harvest of corn silage continued, and farmers began harvesting early maturity soybeans and high moisture corn. However, the wet conditions prevalent at the start of the season that caused planting delays and replanting of many fields has resulted in a lot of variability in maturity stages at this point. Some fields could still benefit from precipitation. Crop condition ratings remained steady, but hay and pasture conditions declined slightly. Some growers began to seed winter wheat.For crop progress numbers around Ohio, click here.
A version of Microsoft’s upcoming Windows 8 operating system has been published to the Web, but there are several reasons that potential pirates may not be able take full advantage of the leak. A “non-boot” version of Windows 8 Enterprise-N appeared on The Pirate Bay, a notorious site for sharing copyrighted software and other works, as well as other sites on the Web.Members or supporters of The Pirate Bay also posted instructions on how to get the uploaded software into an .ISO format, which could be burned to optical media.Windows 8 – Two Weeks EarlyMicrosoft representatives didn’t immediately confirm the leak, which occurred a day after Windows 8 was released to manufacturing (RTM). The first day that users – in this case, developers – should have had access to it was Aug. 15, when the final “RTM” builds become available to Microsoft Developer Network (MSDN) or Technet subscribers. The Enterprise-N version lacks Windows Media Player, a concession to the European Union which ordered Microsoft to strip out the utility to allow other media player vendors to compete fairly.Commenters to The Pirate Bay confirmed that they could get the software up and running, although various error messages were reported and the software was reportedly “slow as hell to download,” in the words of one.A Semi-Legitimate Use?Although the version of Windows 8 on the file-sharing seems clearly intended for software pirates, there might be one semi-legitimate use for it: as “backup media” in case of a problem with a user’s machine. Although Microsoft provides the option for users to buy Windows 8 on a physical disc, the days of “recovery discs” are long gone. So far, Microsoft hasn’t published (or widely published, at least) the locations for .ISO versions of Windows 8. With Windows 7, those files and how to find legitimate copies of them are more widely known.But the Windows 8 (and Windows 7) .ISO file is just one piece of the puzzle. Without a corresponding license key, Windows 8 may just run in trial mode. Eventually – exactly how long isn’t yet clear – that trial mode should expire, and the pirate will likely be back to square one.With Windows 7, Microsoft allowed users of the Windows 7 consumer versions 30 days to enter a valid license key. But enterprise users were offered a < href=“http://technet.microsoft.com/en-us/evalcenter/cc442495.aspx”>90-day trial. However, enterprise users still were forced to enter a valid license key before a 10-day period had expired. At the end of the 10 days, Windows 7 would automatically reboot every hour. The same thing would happen at the end of the 90-day trial.Microsoft hasn’t said how long the RTM version of Windows 8 will operate without a valid license key, however.Microsoft Fights PiracyMicrosoft has worked diligently to cut back on piracy, including suing Chinese resellers and engaging in various technical methods to block pirates. For example, ExtremeTech noted last year that generic volume license keys that pirates exploited wouldn’t be so easily accessible; instead, the installer will ping a Microsoft Web page for the unique key. (The preview version of Windows 8 used a standard, published key, but that’s different.)The bottom line? Owning a valid copy of the software is one thing, but holding a valid license is quite another. That’s not to say a working “keygen” license key generator to create those licenses won’t be eventually be developed and released; a Google search of The Pirate Bay site finds several files that at least claim to be working Windows 7 keygens. But until then, all a potential Windows 8 pirate can claim is access to a potentially dodgy piece of software. They’d probably be better off running the free preview version. markhachman Related Posts IT + Project Management: A Love Affair Massive Non-Desk Workforce is an Opportunity fo… Tags:#enterprise#Microsoft 3 Areas of Your Business that Need Tech Now Cognitive Automation is the Immediate Future of…

IO-Link SSP 3.3 and Bluetooth BLE are widely accepted as industry standards for data exchange with the sensor level. At this year’s SPS, Contrinex presents several new series of compatible devices. While the focus is on data, highlights also include ceramic-coated inductive sensors for use in welding cells.Contrinex’s new cloud-ready smart sensors are perfect for live data monitoring from the heart of an application. By simply configuring an IO-Link parameter, users can output and display sensor data in real time. A selection of predictive maintenance features is also available. Setup is easy, since all data structures are compatible with the Smart Sensor Profile IO-Link SSP 3.3. In SIO mode, these inductive sensors also redefine the benchmark for binary use. By setting one of the IO pins as the input, other signal sources can trigger teach-in of the Smart Sensor, synchronization with other sensors, histogram data logging and basic AND/OR operations. The sensors will be available in 2020.The new YBES light curtains include a Bluetooth-BLE interface. It enables wireless remote configuration and the provision of real-time status or diagnostic data via a smartphone. While providing more functionality (EDM, Restart Interlock, beam coding etc.) and ease of use, installation costs can also be reduced as safety relays are not needed. YBES light curtains are suitable for the highest Type 4 safety requirements of Category 4, PL e and Safety Integrity Level SIL 3. They offer blind zone-free installation and an integrated alignment system.The portfolio of RFID read/write modules with IO-Link interface V1.1 now includes new C44 types (40 x 40 mm) with IP68/IP69K protection. With two operating modes and a selectable “Automatic” mode, their user-friendly design helps reduce programming costs, simplify debugging and support predictive maintenance. When used in SIO mode, 2 outputs are available for configuration onto various signal sources. Transponder history, alarm flags, password protection and a Scan UID function are also available.The Contrinex Weld-Immune range of inductive sensors now includes ceramic-coated types. Alongside excellent immunity to magnetic fields from welding equipment and mechanical shock resistance, the new sensors also feature a robust weld spatter-resistant coating. This coating increases sensor longevity, eases cleaning and helps reduce machine downtime. The new sensors will be available in early 2020.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Chips & Components Continue Reading Previous CEVA: second-generation AI processor for deep neural network workloadsNext Squeezing speech-to-text inference models onto small MCUs

They are almost devoid of hydrogen, which is unusual, as hydrogen is the most abundant chemical element in the universe. EHes are characterized by relatively sharp and strong lines of neutral helium, which indicates low surface gravities and atmospheres dominated by helium. Besides helium, these stars also have significant amounts of carbon, nitrogen and oxygen. EHe was first detected in 1942.The discovery of GALEX J184559.8−413827 was announced in 2011 and was based on the data provided by NASA’s Galaxy Evolution Explorer (GALEX) satellite. Given that the star was classified as a helium-rich “hot subdwarf,” it was put on a target list for observations of chemically peculiar objects with the high-resolution spectrograph (HRS) on the Southern Africa Large Telescope (SALT), located near Sutherland, South Africa.Now, Simon Jeffery of the Armagh Observatory and Planetarium in College Hill, Northern Ireland, presents the results of new observations of GALEX J184559.8−413827 conducted with HRS in March 2017. According to Jeffery, the high-resolution spectrum obtained with the use of HRS indicates that the observed object is a nitrogen-rich EHe star.”A spectroscopic survey of stars classified as helium-rich subdwarfs, especially He-sdB or sdOD using 8m-class telescopes has been undertaken. This paper reports an observation of one such star obtained with the high-resolution spectrograph on the Southern Africa Large Telescope. (…) SALT HRS observations of a faint-blue star previously classified He-sdB (Vennes et al. 2011) demonstrate it to be a nitrogen-rich EHe star similar to the pulsating EHe star V652 Her,” the paper reads.Jeffrey acknowledged that GALEX J184559.8−413827 is four magnitudes fainter than V652 Her. Spectroscopic similarities with V652 Her suggest the new EHe star has similar evolutionary status, which suggests that it formed as a result of a double helium white dwarf merger. Moreover, it also means that GALEX J184559.8−413827 could evolve to become a helium and nitrogen-rich hot subdwarf within about 100,000 years.Notably, GALEX J184559.8−413827 is the first EHe star to be discovered for nearly 40 years. This highlights the extreme rarity of such stars.The question that remains unanswered is whether GALEX J184559.8−413827 also pulsates like V652 Her. So far, no evidence of any periodic variability of the new EHe star was found. Jeffery concluded that his study is promising when it comes to future detections of new EHe stars.”This discovery suggests that there are more EHe stars waiting to be found, at least with relatively low luminosities. A higher signal-to-noise spectrum will allow abundances and other parameters to be refined further,” he wrote in the paper. More information: GALEX J184559.8-413827: a new extreme helium star identified using SALT, arXiv:1706.03377 [astro-ph.SR] arxiv.org/abs/1706.03377AbstractA high-resolution spectrum of the helium-rich ‘hot subdwarf’ GALEX J184559.8-413827 (J1845-4138) obtained with SALT HRS demonstrates it to be the first extreme helium (EHe) star to be discovered in nearly 40 years. A quantitative analysis demonstrates it to have an atmosphere described by Teff = 26 170 +/- 750 K, log g /(cm s^-2) = 4.22 +/- 0.10, and a surface chemistry characterised by CNO-processed helium, a 1% contamination of hydrogen (by number), and a metallicity 0.4 dex subsolar. Its distance and position are consistent with membership of the Galactic bulge. Its sharp absorption lines place strong constraints on both the rotation and microturbulent velocities. Spectroscopically, J1845-4138 closely resembles the pulsating EHe star V652 Her, generally considered to be the product of a double helium white dwarf merger evolving to become a helium-rich sdO star. (Phys.org)—Astronomers have identified another rare example of an extreme helium star. The star, designated GALEX J184559.8−413827 (or J1845−4138 for short), was initially classified as a faint helium-rich “hot subdwarf,” but new spectroscopic observations reveal that this star is more hydrogen-deficient than previously thought. The finding is available in a paper published June 11 on arXiv.org. Explore further
