Study suggest turning off mobile phone etc. devices to not be distracted every couple second when new SMS arrives..

What with Robert Graves? https://en.wikipedia.org/wiki/Robert_Graves Author of "I, Claudius" https://en.wikipedia.org/wiki/I,_Claudius "King Jesus" https://en.wikipedia.org/wiki/King_Jesus "Claudius the God and his Wife Messalina" What with James Clavell? https://en.wikipedia.org/wiki/James_Clavell "Shogun" https://en.wikipedia.org/wiki/Shōgun_(novel) "Tai-Pan" https://en.wikipedia.org/wiki/Tai-Pan_(novel)

I would bother more about hardware specification than OS.. (as long it's Windows) ps. Check whether your external devices are compatible with 10 (empirically, not just by reading websites)... If not, you might be screwed, having to buy more stuff like printer/scanner/digital camera etc. Really? I am comfortable only with WinXP.. And AmigaOS (especially with DOpus Magellan/MUI)...

The more they would read Bible, the less they would read koran...

In laboratory free neutrons are created by bombarding f.e. Deuterium by high energy alpha particle. [math]D^+ + 2.22 MeV \rightarrow p^+ + n^0[/math] (because Deuterium has the lowest energy needed to split it) There are some other unstable isotopes that after bombarding them with high energy particles are releasing free neutrons. F.e. Uranium-235 while fission release ~3 new free neutrons, after bombarding it by 1 free neutron. Neutron is unstable particle, with half-life ~10 minutes, mean-life ~15 minutes. So soon after creation, they decay back to: [math]n^0 \rightarrow p^+ + e^- + \bar{v}_e + 0.782 MeV[/math]

Hello! I made paid application for Android. Published it. And noticed weird message "application is not compatible with your device" after going to Google Play Store website of my application, from either desktop computer and devices. They used to work with application when I was sending them through HTTP/FTP. There is plentiful of threads about "android application is not compatible with your device" on stackexchange etc. websites for programmers. But nothing what they wrote, worked in my case. (one of the most interesting was that some devices have partitions, and have to have application .apk file size smaller than f.e. 32 MB, otherwise devices (mentioned some HTC IIRC), refuse to work with app. People bypassed it by compressing PNG to JPG to reduce file size (obviously there could be used download further data from net by app, but much more complicated, and require your own servers forever available) ). So, I wrote to Google Support, and got following message: "Thanks for contacting Google Play Developer Support. Its against Google Payments policies to purchase your own app, and you'll receive an error message if you try to purchase your own app on Google Play. Its also normal to see the message This app is incompatible with all of your devices due to the same reason. If youd like see what your apps look like from the perspective of a Google Play user, I recommend logging into Google Play with an email address other than the primary email address for your Developer Console. Also, we do provide a method for developers to test their licensing-enabled apps. You can find more information about setting up a testing environment in the Android Developers Help Center. Please let me know if you have any other questions. Regards, Ginny W. Google Play Developer Support" My reply: "Thanks for reply. It makes some sense. But I would suggest changing message to f.e. "You cannot purchase your own application". You would save a ton of time replying for messages like mine own, if developers and users would know why their device is not supported. I saw on Internet plentiful people have problems with "device is unsupported". The more clearer will be explained why it's not supported, the easier will be to find solution... So if f.e. app requires camera, extend message "Application is not supported by your device because [you have no camera] or other message (if app requires some hardware not present in device). etc etc. Just mine suggestion. Send it to higher level manager." Would you like to add something to my reply to Google Developer Support.. ? Best Regards!

"The typical visual absolute magnitude of Type Ia supernovae is Mv = −19.3 (about 5 billion times brighter than the Sun), with little variation.[14]" https://en.wikipedia.org/wiki/Type_Ia_supernova

Even your old CRT TV is particle accelerator.. The largest cost is purchase of vacuum pump device (~$600). Vacuum flask could be used ($10 the last time I bought it 1L volume). Both from chemistry equipment shop. Rectifying diodes and capacitors for Cockcroft-Walton high voltage generator from electronic shop (you could use it also for discharge tube with some gas as medium and observe spectral lines of different gases). The rest of needed things could be found on scrapyard. Build Cloud Chamber to observe cosmic rays, and unstable element isotopes decays.. Cost $50 or so. Aquarium could be reused lated. You should start from finding local supplier of dry ice.

What the real advantages you would have from this display type? Unable to use in darkness,night.. Disadvantage. Little power consumption less. My 24" LED monitor, takes 19.3 W (just measured with watt meter), while the rest of desktop machine up to 500 W (probably average around 200-300 W). That's 5-10% energy less used. 19.3 W * 3600s * 14h/d * 30 d/m / 3.6e6 = 8.106 kWh per month * 0.62 / 3.78 = $1.33 on electricity bill less per month. That's 5% of my total. Optimization always should be started from things that are consuming the most of energy/money/time etc. If you optimize computer program, you run profiler, informing which function is running the slowest and CPU spend the most of its time. You don't start optimize from things that would give barely difference.

If somebody would have NaOH placed in container that is not hermetic, NaOH+CO2 (from air, for months/years) -> NaHCO3 and Na2CO3 After adding almost any stronger acid will release CO2 gas bubbles. From my wikipedia of Sodium Hydroxide, Google translated: "The solid white substance of the crystal structure . It is hygroscopic , easily also combines with carbon dioxide from the air ( forming a coating of sodium carbonate ), so it should be kept in tightly closed containers ." (there would be needed also some red acid to mimics OP observations). ps. I do agree that it's most likely indicator, from what EE described.

Then why do you introduce it? Nobody mentioned measuring gas density, prior you. I said only about measuring gas volume, in graduated cylinder.. Not really, if you don't know concentration. f.e. ethanol mixed with water has density between 0.789 g/cm3 to 1.0 g/cm3 If it's 100% ethanol, 0% water, density is 0.789 g/cm3, If it's 0% ethanol, 100% water, density is 1 g/cm3. If there are used both, density is somewhere in between them. (let's pretend air pressure doesn't matter)

If it releases gas during reaction, you should measure precise mass of either compound, and put graduated cylinder above it, to catch gas and measure its volume. 1 L = ~ 0.04464 mol at room temperature or so. So you will know how much mass/moles of NaOH gave which volume of gas in result. Then check out which gas it is. If it's Hydrogen, fire will cause explosion. If it's Oxygen, fire should be more intense. If it's non-flammable gas, such as Carbon Dioxide or Nitrogen, fire should disappear. According to Internet methyl red is red solid, not (or barely) soluble in water, and soluble in ethanol.

I am using coffee grinder, bought just to mill chemical compounds, then could be used mortar and pestle to smash it even more to fine dust.

Some people in the past mentioned it's related (at least in their case) to used web browser. They said they can quote in one web browser, and can't quote in other one. I am using Mozilla Firefox, and quote function works as expected (as you can see above). You could do it manually though. Just enter [ quote ] prior text, and [ /quote ] after text, without spaces obviously. Eventually switch to raw text mode (the top left button in full editor), then you can copy/edit the all tags. How can you not being able to copy text from website? It's built-in web browser functionality. Web site must intercept RMB context menu to prevent user from using copy functionality (but it still can be bypassed by using Show Source Code). Maybe it's unexpected revelation of virus/Trojan/browser extension/plugin installed and intercepting your data.. ?

Plutonium-238 half-life is just 87.7 years. It's manmade and utilized by humans. Plutonium-244 half-life is 8.00(9)*107 years.. https://en.wikipedia.org/wiki/Isotopes_of_plutonium How can galaxy be rich with Plutonium if it'll all decay within couple hundred millions years? It would have to be produced in larger amount than is decaying..

I saw your video on YouTube where you are showing your solar panels. What I would do is connect them to voltmeter, ampere meter, place above them digital camera, in time lapse mode (f.e. make photo every 1 minute). Send frames to computer, glue them together to movie, and check how it's changing over one whole day (with 30 FPS, 1 minute delay timelapse, 18h would be 36 seconds long) Do you have some old satellite dish? Its curvature could be used to make template. Use f.e. paper put for a few seconds to water, and place on satellite dish, many pages of paper, until you have something looking like dish, but paper one. Wait until its dry. It should be pretty solid (but not waterproof, so you could try painting it to protect it). Place and glue on it broken to little pieces mirrors. Then use it to concentrate Sun energy on your solar panels, and record timelapse video from whole day again, to compare difference. If there will be significant improvement, prepare couple such "concentrators".

Which rock do you have in mind.. ? Pretty common rock is Calcium Carbonate CaCO3. https://en.wikipedia.org/wiki/Calcium_carbonate It's remains of dead millions years ago sea living organisms, such as shells of snails, trilobites. https://en.wikipedia.org/wiki/Trilobite "The exoskeleton is composed of calcite and calcium phosphate minerals in a lattice of chitin that covers the upper surface (dorsal) of the trilobite" Blended to dust, mixed with a lot of water, it could be used as cheap way to decrease acidity, fertilizer, or to fight with pest (f.e. paint bottom of fruit trees) Prior using it you should check pH of your soil (electronic device can be bought for $10 in Leroy Merlin), and read requirements of every your plant. Wrong fertilizer or too large dose can kill them. You can check whether you have CaCO3 by using dust with acetic acid. It should make Calcium Acetate and release plentiful of Carbon Dioxide gas. Calcium Acetate, unlike Calcium Carbonate, is pretty good soluble in water, so used dust should disappear.

Are not you supposed to write source code by yourself? Not try to find ready somebody else source code? Start from finding 68k instruction set, and learn them, at least the one needed for project: https://www.google.pl/?q=motorola+68000+instruction+set Make function waiting 1 second, then make loop for 25*60 seconds calling above wait 1 second function.

Magnetic field lines the best is to visualize with Compass Array device like this one: It costed ~30 usd here. There are 2D and 3D versions. In 3D version compasses can spin in either axis. When you will be moving magnet above it, compasses will change direction instantly. When you will place electromagnet above it, and turn it on or off, swap current direction, compasses will be adjusting their directions depending on current direction.

The really poor people want to be in jail because they will get food for free, and they won't have to search for food in trashcans.. Couple months ago, prisoner was released (end of sentence), and killed girl. He told police and judge, he did it because he wanted to return to jail, as he could not survive on freedom.. Not surprisingly, nobody wants ex-prisoner-employee... Now he has life sentence. Happened not once, nor twice, that retired person started committing crimes to be imprisoned (even some silliness). On freedom had pension disallowing to survive a week.. Homeless people are starting doing some silliness to be imprisoned during autumn-winter here.

If somebody would be slightly more intelligent than average, and desperate to get a job, would investigate what criminal activities/sins made boss/manager/director of company where he/she wants to apply for a job, and "suggest" he/she would be good employee (somebody could call it "blackmailing"). If somebody would be slightly more intelligent than above person, would look at devices currently existing, find a way to improve them a bit, persuade investors to invest money in his/her project, make worldwide/country patent, and become his/her own boss, with majority of shares in newly created company producing more efficient devices. If somebody would be a lot more intelligent that them, would not bother about job, money or anything material.. That's not correct. https://en.wikipedia.org/wiki/Asiatic_lion There is ~523 Asiatic wild lions. ps. IQ test cannot have questions testing Earth's exclusive knowledge. If extraterrestrial life form would land on Earth, he/she/it should be able to perform test. How can he/she/it do it without even knowing what is "lion","dog","mouse",etc. That's not IQ test.. IQ test should be universal for entire Universe life forms.

Then maybe you should learn how to convert Joules to electron Volts, and vice versa? I was talking about abundance of elements. Hydrogen-1 is nearly 74%, while Helium-4 is nearly 24%. The rest is pretty meaningless minute amount. https://en.wikipedia.org/wiki/Abundance_of_the_chemical_elements scroll to section "Abundance of elements in the Universe"

That depends on how these ages of life were spent. Farmer from 3rd world country, not reading any books, because he has not learned it, will most likely have only useful knowledge about vegetables and animals he worked with entire his life.

That reminds me "hypnosis spiral S/F"..

Sunshaker, you should learn first how to create matter and antimatter: http://www.scienceforums.net/topic/92274-say-you-believe-or-else/?p=893302 Even our Sun is creating antimatter (positrons), and it's giving 7.65% of energy that everybody receive on the Earth everyday. http://www.scienceforums.net/topic/85656-solar-fusion-neutrinos-and-age-of-solar-system/ ps. There is minute amount of elements with higher atomic number (proton quantity Z) than 2 in Universe.
