Windows XP Pro runs smoothly on either Core 2 Duo, and mine Core i7 machines.. I don't recall having also problems with Windows ME. Win98 I never had. Obviously there might be problems related to lack of drivers for modern hardware though. Without dedicated drivers, gfx card will run in software frame-buffer mode like in BIOS (no GPU acceleration so everything slooow), built-in mb sfx card won't play, built-in Ethernet card won't send/receive data, USB won't work etc. etc.

These things are correlated. See inverse-square law. [math]P=\frac{P_0}{4*\pi*r^2}[/math] r - distance from Sun to Earth P0 - energy emitted per second. P - energy received per second per m2. Neither power is constant (Sun cycles), nor distance between Sun and Earth, because of elliptical orbit 147 mln km-152 mln km depending on date.

See this thread. I explained fusion process in the Sun very detail way: http://www.scienceforums.net/topic/85656-solar-fusion-neutrinos-and-age-of-solar-system/ f.e. liquid water (that's majority of Earth's surface) is transforming to gaseous state. It takes energy to do so. CO2 + energy -> C + O2, vegetables are consuming carbon dioxide and energy, and carbon is used to build their cells, while Oxygen is released to atmosphere. But majority of energy stored at day, is simply released during night.

Learn how to calculate decay energy (article from my signature), then apply to any unstable isotope (there is 3142 isotopes of 118 elements, majority unstable, so pick up randomly few and calculate D.E.) You will see that (anti)neutrino that's emitted while Beta Decay Plus/Minus, has positive mass, and positive energy. BTW, there is no single energy that has neutrino. It's varying. f.e. Anti-neutrino from Tritium decay has between ~0 to 18.6 keV energy.

Smell has to warn living organism against dangerous molecules. It can't be triggered by the most common substances, because it would be useless feature. Brain/nervous system would be flood with data.

It's indeed very useful. Perfect for self recording video bloggers. You know what you will get, and where camera see center (so you can place your body/head there) while it's already on tripod and you couple meters away. You can also start recording movie/make photo from that range. Camera analyze move of your hand and you control special cursor on screen. IIRC you can see this feature in this review Did you also get AC adapter? http://www.nikonusa.com/en/Nikon-Products/Product/Power-Adapters/EH-67-AC-Adapter.html (it's mentioned on Accessories tab of your link) It will allow to run digital camera long time without batteries. Otherwise they will be gone within 30 minutes or so. You plug it in instead of batteries and second end to home power 230 V/110 V. See also this https://support.nikonusa.com/app/answers/detail/a_id/570/~/can-i-do-time-lapse-photography-with-my-coolpix-camera%3F (for your camera, it might be different model, try to search for it)

Check by yourself on YouTube https://www.youtube.com/results?search_query=sirens+doppler+effect

Yes. Record sound using f.e. digital camera video recorder while police/ambulance/fire fighters will be going.. Then compare sound, when they're approaching, and when they're receding you. If you will be following car with siren, you won't see difference, as both you and that car have similar/equal velocity. Somebody driving car with 70 km/h has speed [math]19.44\frac{m}{s}[/math]. That's 5.7% of speed of sound (340 m/s). Somebody driving car with 100 km/h has speed [math]27.77\frac{m}{s}[/math]. That's 8.17% of speed of sound.

Do you have polarization filters? Do you have source of polarized light to examine in experiment by yourself? Did you even see it on your own eyes? If source of light would be already polarized, your code would fail..

Place laser on fast moving vehicle and turn it on. Laser beam send to receiver. Compare with exactly the same stationary laser. Don't you have ambulance/police/fire department in your area? Difference between sound from vehicle that is approaching/receding is clearly noticeable.

First of all, c'mon, select whole Visual Studio project, zip it and attach. It must works without having to do anything. Nobody will be writing entire program just for your little snippet of code to work.. Secondly, you didn't randomize polarization angle, but you walk through all possible values with constant increment.

My Nikon S6600 writes 1.16 GB per 10 minutes of movie at best quality Full HD (1920x1080), continuous. So on 32 GB card it'll be enough for 275 minutes (4h 35 mins). With lower quality, obviously longer. Probably at 1280x720 it would exceed 10h. But with time lapse (this model doesn't have it automatic, but there are external devices), it would be completely differently calculated, as it's not movie, but image sequence.

That's why I like digital cameras with time lapse feature. You place it on tripod. Set time lapse 1 minute...or.. 1 hour.. Then living. And return days, weeks, months later and glue frames together to one movie. AC adapter needed to camera working non-stop, to not run out of battery. I am doing it with experiments taking long time. Place voltmeter, ampere meter, watt meter, thermometer etc. etc. in front of camera on tripod. Press record. And we have movie. Then just read values at the most interesting moments and enter them to SpreadSheet/Excel.

In democratic countries nobody is going to jail just because YouTube said so. Producer of movie can complain on police, then police might find and arrest person, then it goes to court. It can take months or years. But I never heard about such a case..

That depends on definition what is "illegal video". f.e. video made by somebody else, that you used and uploaded, f.e. some Hollywood movie. They're removed when YouTube is informed by original producer or movie making company that has rights for it. If you will use music that you don't have rights for, it will be also removed. Porno/controversy is another story. I made by myself, and uploaded to YouTube approximately 120 videos. None was removed. Below YT video there are buttons, More, and Report. If somebody will press it, YouTube admins are informed about something wrong with video, and taking look at it.

In western country- probably without problem. In yours, I don't know. I have not seen bad sectors for ages. Couple my disks were running for years constantly 24h/7d in server machine. The main rule is to not spin/move disk while it's running, don't walk with laptop (unless it's SSD), don't shutdown by button but nicely close system software friendly way, use UPS to prevent sudden power off when there is no energy, etc. precautions.. If you will follow rules, chance to get bad sectors decrease.. If you don't care about rules, get SSD next time. Downloading 700 MB takes 70 seconds here.. (couple years ago it would take 47 seconds, but they were sold to worser provider) Let me guess- Hobbit 3rd?

I have no idea what is scilab, but in C/C++ programming rand() function is returning results always the same way in a row. You have to use srand(time()) or similar instead of time() to have real pseudo-random values, every time different. http://www.cplusplus.com/reference/cstdlib/rand/ http://www.cplusplus.com/reference/cstdlib/srand/ Typical application is using rand()/srand(), so try searching for how to feed srand() (shortcut from random seed). http://en.wikipedia.org/wiki/Random_seed Maybe this will help a bit https://help.scilab.org/docs/5.3.3/en_US/rand.html Description "Warning: without a seed, the sequence will remain the same from a session to the other."

Equilibrium between forces from two massive bodies canceling each other is not the same as anti-gravity.

Interactive brain is using Macromedia Flash. Try Chrome, it has built-in flash. It's completely different technique. It's 3D modeled and pre-rendered to sequence of images, that are later showed in right order. Like in Diablo 1 or other isometric '90 games.

Gold, Platinum or Palladium metal, or clean Graphite, for electrodes should be used to produce Hydrogen and Oxygen. And not dissolve electrodes. I am personally using Gold. But you have to use 24 carat Gold, not 14 nor 18 as these have just 58.3% and 75% of Gold.

Are you familiar with Rydberg formula (1888 year)? http://en.wikipedia.org/wiki/Rydberg_formula Which is extension from older Balmer formula (1885 year)? http://en.wikipedia.org/wiki/Balmer_series They both have n parameter, full integer positive. Data for Balmer series are gathered while ionization of Hydrogen gas by high voltage. Equation is describing observation made in laboratory. Schrödinger equation is just extension made 36 years later.

Methane has mass ~[math]16\frac{g}{mol}[/math], so density ~[math]0.716\frac{g}{L}[/math] while CO2 and N2O have ~[math]44\frac{g}{mol}[/math] and density ~[math]1.977\frac{g}{L}[/math] Methane will simply reach much higher altitude in atmosphere, because of its lightness. CO2 is "eaten" by vegetables, and with time its concentration is decreasing when vegetables are growing. While methane will still be in upper atmosphere.

Such devices (balloons) have smaller density than air. Density is mass divided by volume. But density of air is not constant but changing with altitude. So at some higher altitude air will have again smaller density than balloon, disallowing it to fly above this limit. Balloon with attached engines is called Airship http://en.wikipedia.org/wiki/Airship (therefor you can control it and fly where you want) The most famous was Hindenburg http://en.wikipedia.org/wiki/LZ_129_Hindenburg If you want to make something floating in air, increase volume, with same mass as before. f.e. suppose so we have tank with liquid Hydrogen, heat it, and it'll become gas, and fill balloon and whole device will start flying. If you want to land, cool it down and balloon will decrease volume.

It's any ball that was confirmed to have normal weight. f.e. if A=B then either A and B is good.
